[login to view URL] able to detect the screen change event.
[login to view URL] able to get the changed area and generate a image;
[login to view URL] small program should be able run as .exe without any additional installation.
1. Use c or c++ language;
2. Use mirror driver to detect and capture the screen changes(mirror driver is very important).
3. Be able to run in main window operating systems(win7, XP...).
4. Performance should be good. The CPU and memory using rate should be acceptable.
PS: we just need a critical algorithm, not a complete system. So UI can be simple. If you are interested, welcome contact with me. Thanks.
The thing i really care is how to detect the screen has been changed.
Our requirement is to monitor the whole PC screen not specific messages. So how to get a notification that tells me the screen has been changed. We need to call "Mirror Driver" or other ways to hook some system API calls(gdi32.dll probably).
If you think you are able to do these(especially detect this screen changes), feel free to contact with me.
