Hi
I am trying to find the application from a hWnd handle.

ie. if the hWnd is to Internet explorer, I want to try to return
iexplore.exe (as per processes in Task Manager), or some other indicator
that its IE.

Can anyone help?

Thanks

Loop through the process list returned by
'System.Diagnostics.Process.GetProcesses' and compare the handle to the
'Process' objects' 'MainWindowHandle' property value.

Thanks for the reply.
I just found this, literally about 30 minutes ago, and got it working.

Thanks

The problem with MainWindowHandle is that there can only be one per
process, even though applications like Internet Explorer have multiple
top level windows in the same process.
