You should just need this:
[Edit]
Use it like this:
.lib "user32.dll" FindWindow%(ClassName$,Caption$):"FindWindowA" ShowWindow%( hWnd, nCmdShow ) : "ShowWindow"You can copy and paste the Const values (SW_HIDE etc) from Robs code.
[Edit]
Use it like this:
hWnd = FindWindow( "Blitz Runtime Class", "my caption" ) ShowWindow( hWnd, SW_HIDE )
