PRB: MFC Control Panel Applet Shows ODBC Icon in Control Panel

RESOLUTION

If you are not using any of the functions exported by ODBCCP32.LIB, then select the Input category in the Project Settings for the linker, and specify "odbccp32.lib" in the "ignore libraries" field. This is equivalent to adding /nodefaultlib:"odbccp32.lib" in the linker command line.

However, if you have to link in the ODBCCP32.LIB file, then close the workspace, open the .mak file for the project as text, and add "odbccp32.lib" to the linker dependency line as shown in the example below. In the case of the NTCPLAPP sample, you should see lines similar to the following:

   "$(OUTDIR)\MyCplApp.cpl" : "$(OUTDIR)" $(DEF_FILE)$(LINK32_OBJS)
       $(LINK32) @<<
     $(LINK32_FLAGS) $(LINK32_OBJS)
				

These lines are the linker dependency and command line. Each target has these lines. Modify the last line as follows:

   $(LINK32_FLAGS) $(LINK32_OBJS)odbccp32.lib
					

This ensures that functions exported by the ODBCCP32.LIB file are searched last while linking. The CPlApplet is resolved to the one in your code because the .OBJ files are searched prior to the import libraries. If there are multiple targets, the modification needs to be made for all the targets.
