anotherthing: i'm using VC++6, why CreateTimerQueueTimer() isn't in list?
how can i use it without a problems?
From MSDN October 2000:and perhaps you will need the latest SDK (from February 2003) compatible with VC++6.0Quote:
Requirements
Windows NT/2000: Requires Windows 2000.
Windows 95/98: Unsupported.
Header: Declared in Winbase.h; include Windows.h.
Library: Use Kernel32.lib.
sorry where i get that?Quote:

Define "can't execute the exe"
BTW, could you install VC++6.0 on your windows7?

yes i could and was easy. but i install the Visual Studio 98(and better install SP6 for correct the errors).
But why do you execute it directly?Quote:

What messages do you get?
BTW, you have to be an Admin to install anything!
thanks i did by cmd window and extract it and is installingQuote:

ok.. installed and the VC++6 IDE have it on options. but it stills not in list the CreateTimerQueueTimer():(
Did you define the appropriate SDK Headers?
For Windows 200 it must be
_WIN32_WINNT >= 0x0500 and WINVER >= 0x0500
sorry what you mean?Quote:
