Warning: mymodule.arx allocates memory from both MSVCR90.DLL and MSVCR90D.

Anonymous · ‎05-10-2010

I am migrating some modules from AutoCAD 2007 (2008, 2009) to autocad 2010, and some modules show these message when loaded in debug mode.

Warning: mymodule.arx allocates memory from both
MSVCR90.DLL and MSVCR90D.DLL.

any particular reason fot them to start showing this just now? why was it ok in 2007?

thanks in advance

It looks like your project settings have changed, and your new project's
debug build is linking to the debug CRT library.

thanks, I kind of had that in mind, fixed the problem already.

there was actually anoter problem involved, at DllMain, when I called:

@ Global Scope:
{code}
AC_IMPLEMENT_EXTENSION_MODULE(myExtensionModule);
{code}
@ DllMain:
{code}
myExtensionModule.AttachInstance(hInstance);
{code}

it launched an assertion, caused because afxCurrentResourceHandle == NULL.

These somehow was caused because of a little modification I made at sdtafx.h. You guys probably know these piece of code:

{code}
// FOR PROD AUTOACAD WITH DEBUG ARX
#if defined(_DEBUG) && !defined(_DEBUG_WAS_DEFINED)
#define _DEBUG_WAS_DEFINED
#undef _DEBUG
#endif

// some code here (...)

// FOR PROD AUTOACAD WITH DEBUG ARX
#ifdef _DEBUG_WAS_DEFINED
#define _DEBUG
#undef _DEBUG_WAS_DEFINED
#endif
{code}

It was generating these error:

d:\program files\microsoft visual studio 9.0\vc\include\use_ansi.h(49) : fatal error C1189: #error : You have included some C++/C library header files with _DEBUG defined and some with _DEBUG not defined. This will not work correctly. Please have _DEBUG set or clear consistently.

So I removed the code above, these generated the problem at the topic, and the one concearning AttachInstance.
So I put the code back and added #include "use_ansi.h"

{code}
// FOR PROD AUTOACAD WITH DEBUG ARX
#if defined(_DEBUG) && !defined(_DEBUG_WAS_DEFINED)
#define _DEBUG_WAS_DEFINED
#undef _DEBUG
#endif

// some code here (...)

// the solution to my problems
#include "use_ansi.h"

// FOR PROD AUTOACAD WITH DEBUG ARX
#ifdef _DEBUG_WAS_DEFINED
#define _DEBUG
#undef _DEBUG_WAS_DEFINED
#endif
{code}

These solved both problems. I do not know if it is the best solution, but it worked so far...
If somebody knows a more polite solution please tell me.
