Hello,

Hooking BitBlt function in the 'picpick.exe' program and call SendIpcMessage in callback function

Then on some PC's picpick program capture only white screen

if Do not use SendipcMessage then capture is ok.

I don't know why this problem to occur and wonder if there is a solution.

thanks.

How did you set the "handleMessages" parameter in the SendIpcMessage() call? Try if setting it to "false" fixes the problem? You should set it to "true" only if you expect a somewhat longer wait time until the IPC reply arrives.
