I am having trouble getting the window handle of a running application.  I
do not want to match based on window caption text.

I have tried the following:

1) FindWindow - When I specify only the class name I get nothing in return.
Example: FindWindow("WindowsApplication1.Form1", null) returns IntPtr.Zero.

2) Process.GetProcessesByName - This gives me the process but I can't seem
to get the window handle from there.  The MainWindowHandle property returns
IntPtr.Zero if the window is hidden or set to not visible.

3) EnumWindows - Cannot find a way to get the window handle without matching
on caption text.

Any ideas???

Wrong class name. The class name for the window will be something like:
"WindowsForms10.Window.8.app7e" even though the actual class name for your
form may be something like "WindowsApplication1.Form1" - but the class name
will be different for different versions of your app so don't count on it to
always be the same - I think it is assigned by the runtime since it is
"hosting" the app like in a virtual machine.

Use a windows spy app to see what the class name is to pass to FindWindow.

I still have not found a solution.  I did find this article but have not yet
deciphered it:

What are you trying to accomplish? If you are trying to prevent multiple
instances of your app (which you did not mention in your original post) then
you can find a good example in C# here:
