[Linker Warning] Public symbol '_CRInvoiceDate' defined in both module D:\LTDMS\LTDMSA\DMMAIN.OBJ and D:\LTDMS\LTDMSA\ADVER.OBJ [Linker Warning] Public symbol '_CRInvoiceDate' defined in both module D:\LTDMS\LTDMSA\DMMAIN.OBJ and D:\LTDMS\LTDMSA\APPDATEFORM.OBJ [Linker Warning] Public symbol '_CRInvoiceDate' defined in both module D:\LTDMS\LTDMSA\DMMAIN.OBJ and D:\LTDMS\LTDMSA\ASSOC.OBJ [Linker Warning] Public symbol '_CRInvoiceDate' defined in both module D:\LTDMS\LTDMSA\DMMAIN.OBJ and D:\LTDMS\LTDMSA\ASSOCID.OBJ [Linker Warning] Public symbol '_CRInvoiceDate' defined in both module D:\LTDMS\LTDMSA\DMMAIN.OBJ and D:\LTDMS\LTDMSA\BUDGET.OBJ I did a make and a build and got 750+ of these babies. App okay but what would suddenly cause this? Particularly since a project file search yielded no instances of CRInvoiceDate!!! Thanks.

You should be declaring the actual variable in a ..cpp file and then use an 'extern' statement in the header file. Quote: I did a make and a build and got 750+ of these babies. App okay but what would suddenly cause this? Particularly since a project file search yielded no instances of CRInvoiceDate!!! It obviously has to be declared somewhere. Did you recently install/upgrade any components/libraries? What happens when you try to use the code editor's "Find Declaration" feature?
