Instance of another application

I know how to check the instance of the application that is running.
But how can you check the instance of another application that
might be running?  I have tried to use the Windows API call to
FindWindow(...,...) but I may be calling it wrong.  If someone could
point me in the right direction I would appreciate it.

Thanks -- jr

FindWindow(0, "WindowCaptionHere")

I tried FindWindow(0,"CAPTION") already.  I think
my problem is in the declaration of the function.
Is there anything wrong with this?:::

Declare Function FindWindow Lib "User32" Alias
"FindWindowA" (ByVal lpClassName As String,
ByVal lpCaption As String) As Long

I tried without the alias and it wouldn't compile.
Maybe the return type is wrong?  I know the
Function returns an hWnd but the compiler
did not like that either.
