How to see others logging into QQ on the computer is invisible?

A new way to check the invisibility of QQ: When we chat on QQ, there are always some friends who are invisible because of something, which makes our chat unhappy. If you want to verify whether your QQ friends are online, you can use the QQ service of your mobile phone for verification. Recently, I found a simple way to dig out the invisible Q friends without using a mobile phone. 1. Double-click the QQ—— of the offline friend to be verified-the "Send Message" box appears; Click on "Voice Video Chat" on the left, and you can send him a video chat message. You requested a video and voice conversation with *XX*. Please wait for a reply or cancel the pending invitation (the other party is offline or invisible and may not be able to request your video. ) "; How about you cancel it right away? If the other person is invisible, his head will light up immediately. If he really goes offline, it will be dark naturally. In fact, if an invisible friend ignores the pop-up window, his avatar will not light up. If he refuses or closes the window before you press "Cancel", his avatar will light up. Generally, he hates that the window is always open there, and most of them will refuse or close it at once. When we use it, don't press "cancel", and basically we will get the answer later. The old way to check QQ stealth: When OICQ2000 launched the stealth function, many netizens asked how to check QQ stealth users. In the past, many softwares could find invisible users, but they were blocked by Tencent in a few days. Until now, there is no software to check QQ invisibility. Only the following indirect methods can be used: 1: Send information directly to users you suspect of invisibility. Principle: The information sent to offline users is actually sent to Tencent's server for temporary storage, and then sent to users after the other party goes online. In theory, there is no time delay in sending information to offline users, that is, sending information directly to Tencent's server. Information sent to invisible users is delayed. At this time, the process of sending information is: you → Tencent server → the server detects that the other party is online → send information to the other party's QQ. Therefore, by observing the sending speed of QQ information, we can simply judge whether the other party is online. There is almost no delay in sending information to offline users. 2. We use the "mobile QQ" service provided by Tencent, which can be used to find any online friend, whether he is invisible or not. To use this function, you must apply for mobile QQ service first. After the opening of "Mobile QQ Service", mobile phone users can communicate with QQ users' information through SMS server. Click here to learn more about mobile QQ.
