Hi!
I don't know what are you doing with SendMessage(). If you trying to send SC_MOVE command, then use next line:

param2 = 0xF010

It works under Win2000 and I hope will work under WinNT.
If it will not work, then add next lines after SendMessage():

DECLARE INTEGER GetLastError IN WIN32API
?GetLastError()

and tell me error code or find it's description itself using Error Lookup tool.

About working under Win98. Win95/98 and WinNT/2000 are different OS with different realization of API functions. Not always their behaviour identical.


>Thank you for the answer. What I don't understand: why it does work under Win98? The code I've posted is all the code I use. And it works. SendMessage() return value is 0 under WinNt.
