we can't use some API functions in VC++6 such as AlphaBlend or AnimateWindow and so on. Please tell us how can we do. you can sened your answer to : mohsennowruzi@gmail.com or to: abolfazlk@gmail.com thanks a lot

Anyhow, the API calls you want were written AFTER VC6 ( who still uses VC6 ? ) You need to download and install a platform SDK to be able to compile against libraries that include these newer calls.

I don't know about the SDK thing. I had the same problem before in my BugReporter[^] project, and I found that I just had to set the version number higher for WIN_IE or WINVER (can't remember which) in my stdafx.h file. Certain structs, constants, and functions are preprocessed out if your Internet Explorer and/or Windows version isn't high enough My articles www.stillwaterexpress.com BlackDice

AND regardless of the 'WINVER or other settings, if the VC6 header files on your syetm are 'old' enough, and plenty of them are using the riginal installation media (even with the SP5 updates), the API is not even declared in the older header files. Thus your need to downlaod the newer platform SDK libraries and header files AND define the WINVER and other definitions sufficiently high enough. It is not always sufficient to only do one or the other of the two tasks.

I stand corrected. However, the reason I saw it only as the #define's is because I actually had this problem using VC7! So in my case, I already had the correct header files on my system, but the stdafx.h file that was generated when I started my project didn't add the #define's correctly. (I'm more asking than telling) Is this correct? My articles www.stillwaterexpress.com BlackDice

Yes. VC6 - Download newer Platform SDK and add defines. VC7 - Just adjust the defines. At some point, even the VC7 default installation of header files and libraries will be too old, and then it will also need the platform SDK and defines to see the newer API. Using the recent platform SDK and proper defines, and I can build a VC6 program using all the latest Windows XP API just fine.
