PRB: C2188 Error Including AFXWIN.H in an RC File PSS ID Number: Q102699 Article last modified on 03-07-1994

1.00

WINDOWS

= SYMPTOMS =

An attempt to compile resources for an application may fail and the Resource Compiler may generate the following message:

c:

/afx.h(18): error c2188 :#error : Microsoft Foundation Classes require C++ compilation (use a .cpp suffix)

= CAUSE =

The application’s resource (.RC) file includes the AFXWIN.H file. The error occurs because the AFXWIN.H file for version 1.0 of the Microsoft Foundation Classes does not include appropriate preprocessor directives to prevent it from being processed by the Resource Compiler.

= RESOLUTION =

Edit your .RC file to substitute AFXRES.H for AFXWIN.H in the .RC file to avoid this error message. The AFXWIN.H file for version 2.0 of the Microsoft Foundation Classes includes appropriate preprocessor directives to prevent it from being processed by the Resource Compiler; instead, it includes AFXRES.H.

= STATUS =

Microsoft has confirmed this to be a problem in Microsoft Foundation Classes version 1.0 for Windows. This problem was corrected in Microsoft Foundation Classes version 2.0 for Windows.

= MORE INFORMATION =

The following code example generates a C2188 error when you use the AFXWIN.H file for version 1.0 of the Microsoft Foundation Classes libraries for Windows:

Sample Code - TEST.RC
/  Command line needed: rc -r test.rc */
