I am having problems using the MFC template CArray. I am trying to create a CArray of a structure, nothing fancy, and I cannot get it to compile. I have used this successfully under VC++ 6.0 so it is probably just a matter of compiler flags and such. I have the 8.26 CD and have downloaded all the updates. In order to use the CArray<,> I need to include the file <afxtempl.h>. The problem is that if I do include it I get this message: Error: D:\PROGRAM FILES\DM\BIN\..\mfc\include\32-bit\afxtempl.h(305): no But if I do not include the file I get this message: Error: D:\PROJECTS\TESTDLG\CPrompt.h(66): 'CArray' is not a class template match for function '?_P(unsigned ,char *,int )' Thanks!

Yes, you are correct. The following 5 lines are present in MS VC++ files: #ifdef _DEBUG #define new DEBUG_NEW #undef THIS_FILE static char THIS_FILE[] = __FILE__; #endif However, Now I get the compile error, (even with the compiler setting for allowing new[] and delete[] operator overloading): Error: D:\PROGRAM FILES\DM\BIN\..\include\stddef.h(78): not an overloadable operator token.

Silly me! The problem with CArray<> was not due to any DEBUG issue, but with the use of new for arrays. Compiling with -Aa- solved the problem. Cheers!
