I need to save my app's screenshot...

you can simply change 800x600(640x480/1024x768,...)
int x=800;
int y=600;

//use of GetDC()->m_hDC and see result.

//one interesting for you if you want to use of other

CImage m_Image;
m_Image.Attach(hMainBmp);
m_Image.Save("c:\\test.bmp");//use of jpg instead bmp but if you can zip your file its good.
m_Image.Detach();
DeleteDC(m_hdcMem);
DeleteObject(hMainBmp );
DeleteObject(m_OldBitmap);
