A QQ concealed chat software that is used for chatting in the office and does not want others to know.

This is a simple program that I used to do when I was not very busy. Refer to the enumeration source code to find the handle. Since the RichEdit in QQ is not a general RichEdit, it cannot directly send messages to it, so it has been ruined. However, I found a compromise to solve the problem: copy and paste the message to be sent using the analog keyboard, and then send it out.
The control on form1 contains a commondialog: cdlbg universal dialog box for opening files. A timer control: timer1 is used to check whether there are new messages; two text control text2. two pictureboxes: picture1 are used to load the background. Pictemp is used to temporarily store the image on the clipboard. There is a small bug in it, because there is no time to ignore it. It is worth looking at if anyone is interested in studying the handle, or sending and receiving the message mechanism.
I forgot to mention the purpose. This software can be used for QQ chat in the office and you don't want others to know about it. Loading the screen of your usual work, maybe the boss has always thought that you are focusing on your work.
The premise of using this small software is to open the dialog box for chatting with a person (no way, you cannot find the method that does not need to open the chat box. If you have any, please tell me, I will be grateful to you. :). Currently, you can only chat with one person at the same time. Haha, although the function is not very comprehensive, there is still a little bit of small practical, do not believe you try it.
