I've followed your advice to use the following:

DECLARE INTEGER GetActiveWindow IN WIN32API
DECLARE INTEGER ShowWindow IN WIN32API INTEGER hWnd, INTEGER ShowWindowMode
=ShowWindow(GetActiveWindow(),5)

I put the above statements in the Init method of the form but I still could not see my expected application appear as the top most window.

I have 2 applications called server1.exe and client.exe. The client.exe uses timer to check whether there is a signal (via DBF file) from the server1.exe to release current form (process form) and launch another form (lock form).

I click on the server1.exe to trigger the launch the Lock form, the Lock form load behind and not as the foremost window. Why?

Thanks again for your help,
