QQ received a custom expression failure will show a red fork. The last two days are always received by someone else's "unknown expression" (Figure 1), asked each other, said the other party did not send pictures or expressions.
After giving full play to my intelligence and wisdom, finally found the cause of the problem, and has been confirmed by friends-all use of the coral version of QQ friends have more or less encountered this situation. Since it is the reason of "worm", then analyze the configuration file of "worm" son. After the full play of my intelligence, finally found a solution.
Coral version QQ has the initiative to detect the other side of the IP address function, especially in the case of not getting the other IP address, and the other side of the chat, will be through the message to actively detect the IP address of each other, and the beginning of the other side of the IP address information, will not be detected when sending messages, This is why it is not the reason to send "unknown expression" to everyone who chats with each other.
Know the cause of the problem, solve it is simple, into the Coral QQ directory, called "Coralqq.ini" configuration file, find the "msgdetectip=1" line, change it to "msgdetectip=0" Turn off the probe IP function when sending messages ( As shown in Figure 2).
To solve the problem, The hateful "unknown expression" has finally been killed! Do not want to chat QQ time automatically send "unknown expression" friends, turn off the automatic detection of IP function try it.
