conditional compilation .rc file does not work

[sree...@gmail.com]

Hi

I would like to have a version displayed as 6.4.xxx in 64bit build and
6.3.xxx in 32bit built using the same .rc file. Here is the code

#ifdef BUILD64
#define IDD_OPTION_TITLE "6.40.119"
#else
#define IDD_OPTION_TITLE "6.30.119"
#endif

I have defined BUILD64 only in x64 build in VS2008. But both in 32 and
64bit builds i see the version as 6.30.xxx. I changed BUILD64
definition to _AMD64 .. defined in VS. But that does not help. Does
coditional compilation not working in .rc file?

You do know that the preprocessor symbols for the resources are defined
separately from those of the compiler? [Exactly why, I have never been sure.]

See below...

Because it is a separate tool, run from a separate command line (CreateProcess call)? Does
not seem unreasonable that there might be a desire to have various settings.

Need to define preprocessor defines separately for .rc file.

1. Open your project in Visual Studio 2008
2. Right click on resource script file (e.g. app.rc) and select
"Properties"
3. At the top of the property page, select one platform like "Win32"
or
"x64".
4. In the left menu bar, select [Configuration Properties] /
[Resources] /
[General].
5. In the "Preprocessor Definitions" field, add "WIN32" for "Win32"
platform and "WIN64" for "x64" platform. The field value will become
"
WINXX;_UNICODE;UNICODE". (XX will be 32 or 64)
6. Click OK to close the window.
7. Right click on resource script file (e.g. app.rc) and select "View
Code".
8. In the code editor, add #ifdef and #elif to conditionally include
resources when compiling. Use "WIN32" and "WIN64" preprocessor
definitions
that we defined just now. Here is a sample code:
