GetWindow/GetModuleFileName

[Otto]

Tested with XP.
This code works here with FW but not with FWH.
FHW: msginfo(cTask) has always the same value.

Otto,

In 32 bits you have to use GetWindowLong() instead of GetWindowWord():

cTask = GetModuleFileName( GetWindowLong( hWnd, GWW_HINSTANCE ) )

Do you have a list of all the function I have to change.
Thanks in advance
Otto

Otto,

I suggest you to use and review Microsoft help files for Win16 and Win32 APIs. Its not a FWH issue.

Basically if we move from 16 bits to 32 bits, then we are going to use longs (32 bits) instead of words (16 bits).

You may find in Google a complete list of differences between both APIs.
