Description

While building one of my projects in the VC10 RC, i get a couple of RC4011 warnings from MS headers:

C:\Program Files\Microsoft Visual Studio 10.0\VC\include\string.h(54): warning RC4011: identifier truncated to '_CRT_SECURE_CPP_OVERLOAD_STANDA'
  
C:\Program Files\Microsoft Visual Studio 10.0\VC\include\string.h(76): warning RC4011: identifier truncated to '_CRT_SECURE_CPP_OVERLOAD_SECURE'

Why this issue is by design? In my .rc, I include only afxres.h and I get the pair of warnings all the time. It's really annoying.

MS please fixes this.

As of VS 2010 RTM, if you include windows.h in a resource file, the RC4011 error is returned by the resource compiler.

"c:\dev\...\.vcxproj" (default target) (1) ->
     (ResourceCompile target) ->
C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\INCLUDE\memory.h(49): warning RC4011: identifier truncated to '_CRT_SECURE_CPP_OVERLOAD_STANDA' ...        
C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\INCLUDE\memory.h(71): warning RC4011: identifier truncated to '_CRT_SECURE_CPP_OVERLOAD_SECURE' ...

How does one include windows.h in an rc file without having memory.h included?

Thank you for reporting this issue. It turns out this behavior is by design. Resource Compiler has several limitations because RC compiler supports only a subset of the statements a C compiler would support. To conditionally compile your code with the RC compiler, surround code that RC cannot compile with #ifndef RC_INVOKED and #endif.
For example in you test project, surround the #include string.h as follows
#ifndef RC_INVOKED
#include "string.h"
#endif

For more information related to the RC_INVOKED macro, refer to the documentation here http://msdn.microsoft.com/en-us/library/aa381032(VS.85).aspx

Thanks,

Attached test1.zip, containing a project that shows the warning.

It turns out that i'm seeing the warning from a .rc file that indirectly includes windef.h, but the same warning occurs if you #include "string.h" from a .rc file.
