Video Capture

I am programming in Delphi 7. Using:

SFhWnd:=capCreateCaptureWindow ( 'SFWindow',
WS_CHILD or WS_VISIBLE ,
WebCamLeft,WebCamTop, WebCamWidth,WebCamHeight,
MainForm.Handle,0);
capCaptureGetSetup(SFhWnd,@VideoCapturePararameters,sizeof(VideoCapturePararameters));
VideoCapturePararameters.fYield:=true;
capCaptureSetSetup( SFhWnd,@VideoCapturePararameters,sizeof(VideoCapturePararameters));

capCaptureSequence (SFhWnd); etc . . .

To capture input from WebCam to file.
How do I get the program to return control to MainForm without actually clicking with the mouse on the form.
(That works) I wish to process the WebCam input in realt time.
[I have tried SetPriorityClass(MainForm.Handle,HIGH_PRIORITY_CLASS)]
I do not know how to set two threads going which may be an answer?

Did you mean SetForegroundWindow(handle) ?

SetForegroundWindow(handle) is not the problem - the main program 'freezes' (I assume by having lost focus) , though the recording continues and the video window stays live. I have tried running the video on another form and using MainForm.Setfocus - it does not work.

Problem now solved by myself - re-wrote the code from scratch and the program no longer freezes.
(VideoCapturePararameters.fYield:=true; now seems to be working!)

If you have solved your problem yourself.
Then you can ask to have this question [PAQ] & [Refunded]

I would PAQ it for the simple reason, that someone might find your own information handy.
