FIX: Private Enum Statements Cause an Application Error (223133)


The information in this article applies to:

  • Microsoft Visual Basic Learning Edition for Windows 6.0
  • Microsoft Visual Basic Professional Edition for Windows 6.0
  • Microsoft Visual Basic Enterprise Edition for Windows 6.0
This article was previously published under Q223133

SYMPTOMS

A user-created ActiveX control contains several private Enum statements. When this user control is added to a Visual Basic project and the project containing the usercontrol is run, an application error occurs that terminates Visual Basic.

RESOLUTION

You can work around this behavior by declaring your Enum statements as Public rather than Private.

STATUS

Microsoft has confirmed that this is a bug in the Microsoft products that are listed at the beginning of this article. This bug was corrected in Visual Studio 6.0 Service Pack 3.

MORE INFORMATION

This section demonstrates how to create a project that reproduces the bug behavior. The section assumes you are familiar with creating an ActiveX control and adding it to a Standard EXE project.

Steps to Reproduce Behavior

  1. Start a new Standard EXE project in Visual Basic. Form1 is created by default.
  2. On the File menu, click Add Project to add a new ActiveX Control project to the project group. UserControl1 is created by default.
  3. Paste the following code into the General Declarations section of UserControl1: 
    Option Explicit
Private Enum Test1
   Var1
End Enum

Private Enum Test2
   Var2
End Enum

Private Enum Test3
   Var3
End Enum

Private Enum Test4
   Var4
End Enum
  4. Close all the Windows associated with the UserControl. Add a UserControl1 control to Form1.
  5. On the Run menu, select Start, or press the F5 key to start the program. The following error message is displayed:
    This program has performed an illegal operation and will be shut down.
    If the problem persists, contact the program vendor.
