once again i want to clear that what i want to do. i don't want my application to be captured by Driver, means if my application is visible at my side then it should not capture in the desktop image, what i should get is , area behind my application in captured image and that should be transferred at remote site.
Now i think following should be solution for this ( please comment) (Technique 1)
-> i have to pass my application window to ExtEscape() with this option ExtEscape(hdc,WNDOBJ_SETUP,4,(LPCSTR)&hwnd, 0,(LPSTR)NULL);
->so my driver will track changes of that window and give its position in WndObjCallback in WndObj. now i will remove that area from my changed rectangle list so will not get the application in my captured image.
-> now my problem is that how can i get the data behind my application window?
i have other issue also while implementing this as below,
-> when i m sending my Mirror Sample window (from main.cxx file of sample with option -w) ExtEscape() is working fine but while i m sending my application window handle ExtEscape() fails it returns either 0 or -1. for -1 it gives error no 8 in GetLastError().
-> what i m sending is the same for both as this ExtEscape(hdc,WNDOBJ_SETUP,4,(LPCSTR)&hwnd, 0,(LPSTR)NULL); i have define WNDOBJ_SETUP in my application with 4354 as define in winddi.h , as i should mention that this application is working fine for capturing image.
-> so why this is happening ? whats the problem here? please help me out to figure out this problem?
-> is there any other way to solve this problem than Technique 1? please explain in details.
