Help, about mold. Please help me, my brother is very grateful.

Help, about mold. Please help me, my brother is very grateful. Simply put, molds are tools used to shape objects. (This is rotary-according to the different molding materials, molds can be divided into metal molds and non-metal molds. Metal molds are divided into: casting molds (non-ferrous metal die casting, steel castings) and forging molds; Non-metallic molds are divided into plastic molds and inorganic non-metallic molds. According to the different materials of the mold itself, the mold can be divided into sand mold, metal mold, vacuum mold, paraffin mold and so on. Among them, with the rapid development of polymer plastics, plastic molds are closely related to people's lives. Generally, plastic molds can be divided into injection molds, extrusion molds and gas-assisted molding molds.

Mass production of non-sheet metal steel parts-cold heading, die forging, metal die, etc.

Sheet metal discharge-hot rolling, cold rolling, hot rolling and cold rolling

Sheet metal processing-stretching, bulging, bending, stamping and blanking

Non-ferrous metals-die casting, powder metallurgy

Plastic parts-injection molding, blow molding (plastic bottles) and extrusion (pipe fittings)

Other classifications of molds:

Alloy mould

Metal plate mold

Plastic mold

Stamping tool

casting mould

extrusion die

Die casting die

I used to make injection molds. There are so many kinds that it is hard to say which one is more promising. As long as you are proficient in one thing, you can become popular. It depends on what you do, whether you make molds or design molds. Of course, it will be much easier to deal with computers when designing, but you should have a little professional knowledge. If it is only molding, the demand is not big, and more operations will do. Self-study may not be easy. After three years of modeling experience (not much, hehe), I think it's better to actually go to the factory to learn, and be an apprentice for one or two months to at least understand the basic process, so it's better to be a model or a designer in the future. Because it is not easy to learn by yourself just by looking at theoretical things, there are many differences between theory and practice. If you want to learn, you'd better find a factory. It is better to have acquaintances. It is recommended not to go to those training courses.

Please help my brother, thank you very much! You can study at night while working, which is the adult college entrance examination, because only in this way can you qualify for the English exam. After you have passed the exam, you have to face the entrusted exam before you can go abroad. This is simply too difficult. You can endure hardships in the army, but learning is more difficult than training. I advise you to take other roads, such as exporting labor services to the civil affairs department, and you can also make a lot of money. You are a demobilized soldier, and the Civil Affairs Bureau will give you priority. Because the state has given the Civil Affairs Bureau the task of supporting the army, the first thing they have to arrange is to demobilize soldiers. You can try. If you succeed, you can slowly find opportunities to study abroad and stay abroad.

About USB flash drive, I know how to access it. Please help me. I appreciate it. Try another computer to see if your computer is poisoned.

2. If the fault still exists, please take out the USB flash drive file and try.

3. If the test fails, it is estimated that there is something wrong with the USB flash drive.

Thanks to any elder brother and sister who can help me with my math problems: keep a number of three at a time (which means minus one is a multiple of three), two at a time (plus two is a multiple of four) and three at a time (plus two is a multiple of five), so the number of eggs is: the least common multiple of four and five minus two, which is also an integer multiple of three, less than 65433.

Big brother and big sister help. I am grateful to download another PPmate.

What you are using now is a virus, which can't be used.

It is good to download Dot from a regular website, but I don't know if there is such software.

Is a virus attack, pay attention to the virus database update or Kaspersky can solve it.

0X000000 This memory cannot be used as a read solution.

There are many reasons for this phenomenon. First, there is something wrong with the hardware, that is, the memory; second, there are many problems with the software.

One: Let's talk about hardware first:

Generally speaking, computer hardware is not easy to break down. Memory problems are unlikely (unless your memory is really a bunch of miscellaneous brands), and the main aspects are: 1. The memory stick is broken (mostly second-hand memory), 2. Using memory with quality problems, 3. There is too much dust in the golden finger of the memory inserted in the motherboard. 4。 Using different brands of memory with different capacities leads to incompatibility. 5。 Heat dissipation caused by overclocking. You can use the software MemTest to check the memory, and you can thoroughly check the stability of the memory.

Second, if not, troubleshoot the software.

Let's talk about the principle first: there is a place in memory where data is stored called a buffer. When a program puts data into the buffer, it needs a "function" provided by the operating system to apply it. If the memory allocation is successful, the function will return the address of the newly opened memory area to the application, and the application can use this memory through this address. This is "dynamic memory allocation", and the memory address is also the "cursor" in programming. Memory is not always available and inexhaustible, and sometimes memory allocation will fail. When the allocation fails, the system function will return a value of 0. At this point, the return value "0" no longer represents the newly enabled cursor, but a notification sent by the system to the application, indicating that an error has occurred. As an application, you should check whether the return value is 0 after each memory application. If so, it means that there is a fault and some measures need to be taken to save it, which enhances the "robustness" of the program. If the application does not check this error, it will regard this value as an available cursor allocated to it according to "thinking inertia" and continue to use this memory in subsequent executions. The real 0-address storage area stores the most important "interrupt descriptor table" in the computer system, which is absolutely not allowed to be used by applications. In an unprotected operating system (such as DOS), writing data to this address will cause an immediate crash, while in a robust operating system, such as Windows, this operation will be immediately captured by the protection mechanism of the system, and as a result, the operating system will forcibly close the wrong application to prevent its error from expanding. At this time, there will be an error that the memory cannot be "read", indicating that the referenced memory address is "0x00000000". There are many reasons for the failure of memory allocation, such as insufficient memory and mismatched system function versions. Therefore, this kind of allocation failure is common after the operating system has been used for a long time, a variety of applications (including virus programs installed unintentionally) have been installed, and a large number of system parameters and system files have been changed.

In an application that uses dynamic allocation, it sometimes happens that the program tries to read and write the memory that should be available, but for some reason, the expected available cursor fails. Maybe you "forgot" to ask the operating system for allocation, or maybe the program itself cancelled this memory at some point and "didn't pay attention" and so on. The logged-out memory is reclaimed by the system, and its access rights no longer belong to the application. Therefore, reading and writing operations will also trigger the protection mechanism of the system. The only final result of the program that attempts to "violate the law" is * * * to terminate the execution and recover all resources. The laws of the computer world are still much more effective and severe than human beings! A situation like this is a BUG in the program itself, and you can often reproduce the error in a specific operation sequence. The invalid cursor is not always 0, so the memory address in the error prompt is not necessarily "0x00000000", but it can also be other random numbers.

First of all, it is suggested that:

1, check the system for Trojan horses or viruses. In order to control the system, such programs often modify the system irresponsibly, resulting in abnormal operating system. We should strengthen our awareness of information security at ordinary times, and never be curious about executable programs with unknown sources.

2. Update the operating system so that the installer of the operating system can copy the correct version of the system file again and correct the system parameters. Sometimes there are bugs in the operating system itself, so pay attention to installing the officially released upgrade program.

3, try to use the latest official version of the application, Beta version, trial version will have bugs.

4. Delete and recreate the files in the Winnt\System32\Wbem\Repository folder: right-click My Computer on the desktop, and then click Manage. Under Services and Applications, click Services, and then close and stop the Windows Management Instrumentation service. Delete all files in the Winnt\System32\Wbem\Repository folder. Please back up these files before deleting them. ) Open services and applications, click Services, and then open and start the Windows Management Instrumentation service. When the service is restarted, these files will be recreated according to the information provided in the following registry key: HKEY _ local _ machine \ software \ Microsoft \ WBEM \ CIMOM \ autorecovermofs.

Here are a few examples to analyze:

Example1:"0x037 13644" memory referenced by "08ba9ef" instruction or "0x0000000" memory referenced by "0x70dcf39f" instruction appears in IE browser. The memory cannot be read. To terminate the program, click OK in the message box. After clicking OK, the message box "An internal error has occurred, and a window you are using is about to close" appears. After closing the prompt message, IE browser also closes. Solution:

1. Start-execute the window, enter "regsvr32 actxprxy.dll" and press enter, and an information dialog box "DLLRegisterServer in actxprxy.dll" will appear and confirm. Then execute the following commands in turn. Some people say this method is unnecessary, but re-register those. Dll will not damage the system. Anyway, it is enough to do everything to solve the problem. )

Registrar of shdocvw.dll 32

Registrar of oleaut32.dll 32

Registrar of actxprxy.dll 32

Registrar of ms.dll 32

Registrar of msjava.dll 32

Registrar of browseui.dll 32

Registrar of urlmon.dll 32

2. Repair or upgrade IE browser and patch the system at the same time. One of the repair methods I have seen is to restore the system to its initial state. It is recommended to upgrade IE to 6.0.

Example 2: Some application errors: "0x7cd64998" instruction refers to "0x 14c96730" memory. The memory cannot be read. Solution: Win XP's "pre-reading" technology, an optimization technology, has also been applied to applications. The system analyzes the previous startup of each application, then adds a virtual "memory image" describing the requirements of the application, and stores this information in the Windows\Prefetch folder. Once the image is created, the loading speed of the application software will be greatly improved. The read-ahead data of XP stores the information of the last eight system startup or application software startup. It is recommended to replace the virtual memory and delete all *. The PF file is placed in the windows\Prefetch directory, so that windows can collect the physical address of the program again.

Example 3: Double-click the "AutoRun.exe" file in the CD under XP to display the "0x00000078" memory referenced by the "0x77f745" instruction. Memory cannot be "written". To terminate the program, click OK, but it works normally in Windows 98. Solution: This may be a compatibility problem of the system. For winXP system, right-click the AutoRun.exe file, properties and compatibility, select Run this program in compatibility mode, and select Windows 98/Me. Win2000, if the SP is patched, just start execution, and enter: regsvr32c: \ winnt \ apppatch \ Slayer ui.dll. Right-click and the properties and compatibility options will also appear.

Example 4: An error occurred when closing RealOne Gold. It used to be normal, but recently the "0xffffffff" memory referenced by the "0xffffffff" command appears every time it is closed. Memory cannot be a "read" hint. Solution: When the input method used is Microsoft Pinyin Input Method 2003 and the language bar is hidden (no problem when it is not hidden), this problem will occur when RealOne is closed, so you can display the language bar before closing RealOne or use any other input method as the current input method to solve this problem.

Example 5: My hero Super Jieba can't play after surfing the Internet. Every time you are prompted that the memory "0xff0000 1 1" referenced by the command "0x060692f6" (every change) cannot be read. Please press OK to terminate the program. Solution: try to make up the hero's super solution. If it will be refilled, you can try to download the corresponding version of the patch from official website. Not yet, so I have to try another player.

Example 6: Double-click the shortcut of the game. The instruction "0x77f5cd0" refers to the memory "0xffffffff" and cannot be read, indicating that the Client.dat program is wrong. Solution: Recharge the latest driver of graphics card, and then download and install DirectX9.0.

Example 7: My friend sent me a message, and my computer got an error message: the memory "0x00303033" referenced by the instruction "0x772b548f" could not be "written", and then QQ automatically went offline, and then I opened QQ and found more than a dozen messages sent by him. Solution: This is that the other party uses the QQ BUG to send special code, and there is an error in QQ. Just patch or upgrade to the latest version and it will be fine.

Unable to read or write to memory solution keywords: unable to read and write to memory.

Several articles related to online search.

the first

Users who use the Windows operating system sometimes encounter the following error message:

The "0X" command refers to "0x00000000" memory, which cannot be read or written, and then the application is closed.

If you ask some "experts", the answer you get is often indignation and disdain like "Windows is so unstable". In fact, this error is not necessarily caused by the instability of Windows. This paper will briefly analyze the general reasons for this error.

1. The application could not check the memory allocation.

When a program needs a memory to store data, it needs to use the "function function" provided by the operating system to apply. If the memory allocation is successful, the function will return the address of the newly opened memory area to the application, and the application can use this memory through this address. This is "dynamic memory allocation", and the memory address is also the "cursor" in programming. Memory is not always available and inexhaustible, and sometimes memory allocation will fail. When the allocation fails, the system function will return a value of 0. At this point, the return value "0" no longer represents the newly enabled cursor, but a notification sent by the system to the application, indicating that an error has occurred. As an application, you should check whether the return value is 0 after each memory application. If it is, it means that something is wrong, and some measures need to be taken to save it, which enhances the "robustness" of the program. If the application does not check this error, it will regard this value as an available cursor allocated to it according to "thinking inertia" and continue to use this memory in subsequent executions. The real 0-address storage area stores the most important "interrupt descriptor table" in the computer system, which is absolutely not allowed to be used by applications. In an unprotected operating system (such as DOS), writing data to this address will cause an immediate crash, while in a robust operating system, such as Windows, this operation will be immediately captured by the protection mechanism of the system, and as a result, the operating system will forcibly close the wrong application to prevent its error from expanding. At this time, the above-mentioned "write memory" error will appear, indicating that the referenced memory address is "0x00000000". There are many reasons for the failure of memory allocation, such as insufficient memory and mismatched system function versions. Therefore, this kind of allocation failure is more common after the operating system has been used for a long time, various applications (including virus programs that have been unintentionally installed) have been installed, and a large number of system parameters and system files have been changed.

Second, the application referenced an abnormal memory cursor due to its own BUG.

In applications that use dynamic allocation, it sometimes happens that a program tries to read and write a memory that should be available, but for some reason, the expected available cursor fails. It may be "forgetting" to ask the operating system for allocation, or it may be that the program itself cancelled this memory at some point and "didn't pay attention". The logged-out memory is reclaimed by the system, and its access right no longer belongs to the application, so the reading and writing operation will also trigger the protection mechanism of the system, and the only final result of the program that attempts to "violate the law" is that * * * stops execution and recovers all resources. The laws of the computer world are still much more effective and severe than human beings! A situation like this is a BUG in the program itself, and you can often reproduce the error in a specific operation sequence. The invalid cursor is not always 0, so the memory address in the error prompt is not necessarily "0x00000000", but it can also be other random numbers. If the above error prompts often appear in the system, the following suggestions can be explained:

1. Check the system for Trojan virus. This program often irresponsibly modifies the system in order to control it.

Cause the operating system to be abnormal. We should strengthen our awareness of information security at ordinary times, and never be curious about executable programs with unknown sources.

2. Update the operating system so that the installer of the operating system can copy the correct version of the system file again and correct the system parameters.

Sometimes there are bugs in the operating system itself, so pay attention to installing the officially released upgrade program.

3. Try a new version of the application.

Mode:

Replace virtual memory

Answer:

So far, yes, that is, if it doesn't happen again when the next cold weather comes, it means this is the main reason.

Append:

If you use Ghost to restore OS, it is recommended to delete all *. PF file, because WINDOWS needs to collect the physical address of the program again.

Some applications will make errors in the "0x 14c96730" memory referenced by the "0x7cd64998" instruction. It follows that the memory cannot be "read".

Source:

Win XP's "pre-reading" technology

This optimization technique is also suitable for application software. The system analyzes the previous startup of each application software, then adds a virtual "memory image" describing the application requirements, and stores this information in the WINDOWSPREFETCH folder. Once the image is created, the loading speed of the application software will be greatly improved. The read-ahead data of XP stores the information of the last eight system startup or application software startup.

Postscript:

At present, this method is unique to the network (the code itself has been studying this problem for a long time), and it is also a common problem. Originally, some programs were read almost every day after the software was closed. ......

Not anymore.

the second

When executing some programs, sometimes there will be a memory error prompt (the content after 0x may be different), and then close the program.

0x instruction refers to 0x memory. The memory cannot be read.

The "0x" memory referenced by the "0x" instruction cannot be "written".

I wonder if you have ever seen such a fault.

Generally, this phenomenon has many aspects, one is hardware, that is, memory, and the other is software, which has many problems.

Let's talk about hardware first:

Generally speaking, memory problems are unlikely. The main aspects are: the memory stick is broken, the memory quality is problematic, and the memory of two different brands with different capacities is mixed, which is also prone to incompatibility. At the same time, pay attention to heat dissipation, especially after overclocking. You can use the software MemTest to check the memory, and you can thoroughly check the stability of the memory.

If you have dual memory, and this problem occurs when different brands of memory chips are mixed or you buy second-hand memory, then you should check whether there is a memory problem or it is incompatible with other hardware.

If not, troubleshoot the software.

Let's talk briefly about the principle first: there is a place in memory where data is stored called a buffer. When the program puts the data in one place, it will overflow because of insufficient space. For example, a bucket can only hold one catty of water. If you put two Jin of water in it, it will overflow. The system is displayed on the screen. This problem often appears in windows2000 and XP systems. Windows 2000/XP has very strict requirements on hardware. When encountering deadlock, overflow or illegal operation of resources similar to Windows 98, the above situation will occur in order to keep the system stable. In addition, it may also be caused by poor compatibility between hardware devices.

Let me give you an analysis from several examples:

Example 1: Open IE browser or "0x00000000" memory referenced by "0x70dcf39f" command will appear in a few minutes. The memory cannot be read. To terminate the program, click OK in the message box. After clicking OK, the message box "An internal error has occurred, and a window you are using is about to close" appears. After closing the prompt message, IE browser also closes. Solution: Repair or upgrade IE browser and patch it at the same time. I see that there is a repair method that Win2000 is self-upgrading, that is, Win2000 is upgraded to Win2000. In fact, this method is to restore the system to the initial state. For example, if your IE is upgraded to 6.0, it will be changed to IE5.0 after the upgrade.

Example 2: Double-click the "AutoRun.exe" file in the CD-ROM under windows xp to display the "0x00000078" memory referenced by the "0x77f745" command. Memory cannot be "written". To terminate the program, click OK, but it works normally in Windows 98. Solution: This may be a compatibility problem of the system. For winXP system, right-click the AutoRun.exe file, properties and compatibility, select Run this program in compatibility mode, and select Windows 98/Me. Win2000, if the SP is patched, just start execution, and enter: regsvr32c: \ winnt \ apppatch \ Slayer ui.dll. Right-click and the properties and compatibility options will also appear.

Example 3: An error occurred when closing RealOne Gold. It used to be normal, but recently the "0xffffffff" memory referenced by the "0xffffffff" command appears every time it is closed. Memory cannot be a "read" hint. Solution: When the input method used is Microsoft Pinyin Input Method 2003 and the language bar is hidden (no problem when it is not hidden), this problem will occur when RealOne is closed, so you can display the language bar before closing RealOne or use any other input method as the current input method to solve this problem.

Ex. 4: My hero Super Jieba can't play after surfing the Internet. Every time you are prompted that the memory "0xff0000 1 1" referenced by the command "0x060692f6" (every change) cannot be read. Please press OK to terminate the program. Solution: try to make up the hero's super solution. If it will be refilled, you can try to download the corresponding version of the patch from official website. Not yet, so I have to try another player.

Solution: This is that the other party uses the QQ BUG to send special code, and there is an error in QQ. Just patch or upgrade to the latest version and it will be fine.

Cause solution

1 The memory stick is broken. Replace the memory stick.

2 dual memory is not compatible with using the same brand of memory or only using one memory.

3 memory quality problems replace the memory stick

4. Heat dissipation problem Strengthen the internal heat dissipation of the chassis

5 Memory and motherboard are not inserted correctly, or other hardware is incompatible. Reinsert the memory or replace the slot.

There is something wrong with the hardware. Replace hard disk

7 driver problems recharge the driver. If it is a new system, the motherboard driver should be installed first.

8. The software is damaged and refilled.

9 software BUG patch or update to the latest version.

10 software is incompatible with the system. Patch the software or try the compatibility mode of the system.

1 1 There is a conflict between software and software. If any new software has been installed recently, try uninstalling it.

There is a problem with 12 software using other related software. Recharge related software. For example, there will be an error when playing a file in a certain format. Maybe there is something wrong with the decoder of this file.

13 virus protection

14 Antivirus software conflicts with the system or software. Because antivirus software enters the underlying monitoring system, it may conflict with some software. Try uninstalling it.

15 system itself has a problem. Sometimes the operating system itself has bugs. Pay attention to the installation of official updates, such as SP patches, and it is best to install them. If it doesn't work, refill the system or replace it with another version.

[Say it again]

Check whether you have Microsoft NET installed. Add/Remove Frames from Programs in Control Panel. If it is already installed, consider uninstalling it. Of course, if you need a net. The framework is in other programs in the future, and you can reinstall it.

In addition, if you use ATI graphics card and SP2 patch (some ATI graphics card drivers need to be in the normal working environment of NET. Framework). In this case, you can find an ATI graphics card driver that does not need the support of NET.Framework.

If the above two methods can't completely solve the problem, you can try using IE repair software to check whether there is a virus or something.

Microsoft network. The framework should be upgraded to version 1. 1.

[One more thing]

Method 1:

Friends of Microsoft News Group give directions: Start-Execute: REGSVR32 jscript.dll.

Start-Execution: REGSVR 32 vbscript.dll

But it doesn't solve-but it provides a way-to register all DLLs at once.

The search query method is as follows:

At the command prompt, enter cmd and press enter.

Used for% 1 in (%windir%\system32\*). regsvr32.exe/s % 1

If you enter this command correctly, you will see a fast scroll, otherwise ... otherwise failure will not have this effect. After entering the car, wait slowly (it takes some time 1-2 minutes) before opening it.

Method 2:

This is a typical problem ~ ~ ~ There are many reasons for this problem. Generally speaking, it is to patch the system for memory and change the slot for memory. [System patches can be updated online on the Microsoft Update website]

There are many reasons for this problem, so we can't simply draw a conclusion. It may be helpful to try the following:

1。 Make sure to use unmodified software (non-Chinese, cracked version)

2。 Try not to run other software when using the modified software. This is a temporary document. Some software may also be using temporary folders, causing interference. )

3。 Turn off all those desktop tools and memory sorting tools (you have at least two similar tools running). "

Treatment method:

Execute regedit to enter the registry file. Under the hook of HKEY _ local _ machine \ software \ Microsoft \ Windows \ currentversion \ Explorer \ Shelleexecute, there should be only one normal key value "{aeb6717e-7e19-1/kloc-0-"

[My personal final solution and opinion]

I tried many methods today, and finally found that the problem was Microsoft's NET.Framework. I upgraded this software and patched it. After a short period of calm, there was a situation that "the memory could not be read". Later, inspired by the above article, I uninstalled Microsoft's NET. Frames 1.0 and 1. 1, all is well.

In addition: if the above situation occurs when opening "My Computer" and "My Documents", there is another possibility that your right-click menu is too bloated, so just clean up the right-click menu problem at this time.

-

[Test Results]

Among the above methods, the most effective and thorough method is as follows:

At the command prompt, enter cmd and press enter.

Used for% 1 in (%windir%\system32\*). regsvr32.exe/s % 1

Skill If you are afraid of making mistakes, you can copy this command and click C: \ in the upper left corner of the command prompt box. Using the following "edit-paste" function, it is not easy to make mistakes. After the quick scrolling is completely still, don't start other programs in a hurry, wait patiently for a while, because the dll is still looking for a location. Don't do anything else until the indicator light stops flashing.

I'm grateful to you, big brothers and big sisters, for taking a look at the configuration? Computer configuration?

Urgent! Sincerely ask for help, please help me, thank you very much. There are still half a year. If you really make up your mind, there is still hope. You must hold out until the end. You can find a teacher to help you. Everyone should review. Maybe time is running out. The key is yourself. Teacher Zhao will mention it, and you will benefit a lot. In a word, you should study hard. Let's go
