SYMPTOMS

If you move a procedure to the beginning of a class module above a Enum or Type statement and then recompile the project with Binary Compatibility set, a version incompatibility error similar to the following occurs where "Test" is the name of an Enum:
"Enum "Test" exists in the version-compatible component, but not in the current project"

RESOLUTION

If the procedure is placed below the Enum and Type Statements, the project recompiles with no compatibility error.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article.

Steps to Reproduce Behavior

  1. Create a new ActiveX DLL project in Visual Basic. Class1 is created by default.
  2. Paste the following code into Class1: 
          Public Type Type1
         i As Integer
      End Type

      Public Enum Test
         Red
         Yellow
         Green
      End Enum

      Public Sub Test3()
      End Sub
  3. In the Property window of Class1, set Instancing to GlobalMultiuse.
  4. Compile Project1.Dll by selecting Make Project1.Dll from the File menu.
  5. From the Project Menu, select Project1 Properties, click the Component tab, and then check Binary Compatibility.
  6. In Class1, move the section of Sub Test3() to be above Enum Test.
  7. Re-Compile the project as "Project2.dll" by selecting Make Project1.dll from the File menu. Change the filename to Project2. Note that the following error occurs:
    "Enum "Test" exists in the version-compatible component, but not in the current project"
    If you move Sub Test3() back to its original position and recompile as Project2.dll, then it compiles successfully.
