PRB: App Studio Does Not Evaluate RC File Constant Expression


The information in this article applies to:

  • The App Studio
    • Microsoft Visual C++ for Windows, 16-bit edition, versions 1.0, 1.5, 1.51, 1.52
    • Microsoft Visual C++, 32-bit Editions, versions 1.0, 2.0, 2.1, 4.0, 5.0, 6.0


An attempt to use a constant integer expression to define a resource identifier in an application's resource (.RC) file fails. App Studio version 1.x displays the following message:

Error RW2002: File not found: <resource>

Visual C++ version 2.x displays the same message if a .RC file containing a constant integer expression used to define a resource identifier is loaded into App Studio or opened in the development environment. Under these circumstances, Visual C++ versions 4.x and 5.0 display a similar, but slightly different message:

error RC2135: file not found: <resource>


Use a text editor to modify the resource file. Place the statements that include an expression into an "#ifndef APSTUDIO_INVOKED" block. App Studio does not automatically read that portion of the resource file for editing and App Studio does not list those resources as part of the .RC file. Use a text editor to make any further changes to those lines.


To demonstrate this situation, place the following statements into a resource (.RC) file:

   #define MyResourceID 3
   MyResourceID+2 bitmap MyBitmap.bmp 

To work around this situation, modify the resource file as follows:

   #define MyResourceID 3
   MyResourceID+2 bitmap MyBitmap.bmp
