What has a BMP to do with a video ?

Please tell where you need a HWND for first.

What is "MYPROG" ?
Is it "MY WEBCAMCAP" or  "OTHER  PROGRAM WHERE I SHOW THE VIDEO"

Which program is executing that statement ?

Please start to explain better what is going on.

Until now you did not anything with FORM or DESKTOP. Do you mean the
use of a TForm ? Or using GetDesktopWindow() ? Then you should
have told also where you needed the handle for.

Better put all the code in the constructor. FormCreate() can be
tricky to use.

Please supply the type of used variables.

I see that you only very much later in your code check if the library
is loaded. Would not it be better to check that right now?

If you wanted to use that that better:

	HWND hForm = Handle;

This is never used inyour code. Please post as little code as possible
to reproduce the problem. (But with all types, that compiles).

After this statement you go on. Is that what should be done ?

Did you try with hForm = NULL already ?

Here you quoted all the code of your first post.
Please do not quote complete posts. We had read that already.
