FIX: Functions Exported Incorrectly in MASM 6.1 WINDLL Sample

RESOLUTION

There are two solutions (described below) to the problem. If you have the Microsoft Windows Software Development Kit (SDK), you can choose either solution. The SDK is relevant because RC.EXE is required to build SYSDATA.EXE. RC.EXE is shipped with the SDK and is not included with MASM.

• If you have the SDK, you can rebuild SYSDATA.EXE using SYSDATA.MAK. This uses the import library produced from building SYSINFO.DLL--SYSINFO.LIB. When you run the rebuilt SYSDATA.EXE, the correct data is displayed.
• If you do not have the SDK, you need to first modify SYSINFO.DEF so that it resembles the following:

        EXPORTS
                GetSysTime   @1
                GetSysDate   @2
                GetSysInfo   @3
                WEP          @4   RESIDENTNAME
  						

  After making the changes, rebuild SYSINFO.DLL using SYSINFO.MAK. When you then run SYSDATA.EXE, it will correctly reference the functions within the rebuilt SYSINFO.DLL and display the correct data.
