Thanks for the info, though it wasn't necessary. :) --Rick 04:59, 8 November 2007 (EST)

So you found something similar, or you just intend to rediscover/recompile for each new version? Not being snarky here, honestly curious.

Suspend

On another topic, I was looking at reveal's main.cpp and saw a bug. You're not suspending/resuming the process. The problem is that process handles are not thread handles, and SuspendThread() and friends use thread handles. You do this:

GetWindowThreadProcessId(window, &pid);
[...]
SuspendThread(process);
cleanMap(process);
ResumeThread(process);
CloseHandle(process);

But you need to do something like this:

thread = GetWindowThreadProcessId(window, &pid);
[...]
SuspendThread(thread);
cleanMap(process);
ResumeThread(thread);
CloseHandle(thread);
CloseHandle(process);

That's probably a leftover from having old code laying around, I know I fixed this in some other tools but forgot to update older ones. Thanks! --Rick 13:08, 8 November 2007 (EST)
