George,

All I was trying to do originally was to get a handle (hWnd) to a
form that I could feed to a DLL call to point to where the display
output of my Video Capture card was shown in...

After many tries to get just a regular handle to a form/window,
it looks like MS is not supplying that information to us for VFP.

It looks like I'm going to have to try using the FoxHWnd control
as my capture window....That will probably work....

As for the SetFocus() Win32 API call, I was just using it to test if
I had the correct Window Value...Being that that didn't work, I had
to Get the title to see which window handle it pointed to...
I think MS doesn't want us to get to that low of a level and just
make everyone do OOP...


Apparently the only valid Window handles you can get for VFP are the
Main Window and Form windows.....All the other controls are handled
in a different manner in VFP.....(Some kind of a bitmap thing...I don't
know the details..)

As I said before, the only call that gets the correct handle for a
Define Window is the GetWindow call...

I wonder if VBasic and VC++ are destined to go this route or what...

(Thanks for all your work on this issue....)

I created an identical form and did the same thing, simply changing the element number. In the click event of the command button on each form, I called the SetFocus API call, using the element of the array that applied to the other form. I'm sure you get the idea of how to apply this.
