Reading screen image using winvnc

[Pick]

I am trying to use ultravnc to control a program that I don't have the source code for. I want to watch the screen looking for certain images in certain locations, then I'll do some mouse clicks. So, I added a routine into vncbuffer.cpp, and called it from vncdesktopthread.cpp near line 919, as shown below:

//Check all regions for changed and cached parts
//This is very cpu intensive, only check once for all viewers
if (!checkrgn.is_empty())

m_desktop->m_buffer.CheckRegion(changedrgn,cachedrgn, checkrgn);

//******START OF ADDED CODE
m_desktop->m_buffer.CheckScreen ();
//******END OF ADDED CODE

updates.add_changed(changedrgn);
updates.add_cached(cachedrgn);

Then, in my CheckScreen routine, I watch m_mainbuff for the images. (I've also tried watching m_backbuff.) I can see the images appear over on the vncviewer computer, so I know they're there and have been sent out. Sometimes my routine sees them and sometimes it doesn't. It seems as though there is another place in winvnc where the screen can be read and sent out. Does anyone know if there is? I've tried fiddling with the settings quite a bit and some things seem to help, but I haven't found anything that makes it work perfectly all the time. I am working with Windows 2000.

Hello,

VNC is porbably not what you want,
