DirectDraw on WinNT4
-
Hi. My application was designed for Win2000 only (I use DirectX 7). And I plan to detect attempt to run this on WinNT4 , because there is error message "The procedure entry point DirectDrawCreateEx could not be located in the dynamic link library DDRAW.dll, but this message show up before WinMain call. Thanks for advise.

Afaik you can't run DirectX > 3 on Windows NT 4.0. ( Execute-buffers, you've got to love them... ;) ) -=jarl=-
I know this, but I need only valid error report, maybe like this: "This program requiedWin98/2000 only" :) I need to detect OS version BEFORE the program say "...Entry Point for DirectDrawCreateEx was not found..." I think that in DDRAW.dll in DllEntryPoint there is call of DirectDrawCreateEx and i have this error message before Step IN to WinMain

As you have found, the OS loader is trying to bring in functions / dlls that aren't there. There are two ways around this. Actually, they are effectively the same, but you do different things. 1/ Delay load (e.g.) ddraw.dll and catch the DirectDrawCreateEx function failure with an exception handler, or 2/ Explicitly load the function using LoadLibrary and GetProcAddress.
