XL97: Problems When you use Macro to Add Control to UserForm

• Microsoft Excel 97 for Windows

SYMPTOMS

In Microsoft Excel 97, you may have difficulty adding a control to a UserForm programmatically. For example, if you run the following macro code:

   Sub Add_Control_Test()

       Set y = UserForm1.Controls.Add("Forms.CheckBox.1","MyControl",true)

   End Sub

CAUSE

The aforementioned macro will not add the control to the UserForm because this syntax for the Add method only applies during run-time. That means you have to include this macro code in an event procedure tied to the UserForm.

The Visual Basic procedures in this article are provided 'as is' and Microsoft does not guarantee that they can be used in all situations. While Microsoft support engineers can help explain the functionality of a particular macro, they will not modify these examples to provide added functionality, nor will they help you construct macros to meet your specific needs. If you have limited programming experience, you may want to consult one of the Microsoft Solution Providers. Solution Providers offer a wide range of fee-based services, including creating custom macros.

If you want use the above macro to add a check box control to a UserForm during run time, do the following:

1. Open a new Microsoft Excel workbook.

2. In the Visual Basic Editor, insert a new UserForm.

3. With the UserForm active, click Code on the View menu.

4. Click the Procedure drop-down in the UserForm1(Code) window and select Initialize in the drop-down list.

1. Add code to this subroutine so it resembles the following:

      Private Sub UserForm_Initialize()
   
          Set y = UserForm1.Controls.Add("Forms.CheckBox.1","MyControl",true)
   
      End Sub
   
   

1. Click the Procedure drop-down in the UserForm1(Code) window and select AddControl in the drop-down list.

2. Add code to this subroutine so it resembles the following:

      Private Sub UserForm_AddControl(ByVal Control As MSForms.Control)
   
          UserForm1.Controls(CheckBox1).Caption = "test"
   
      End Sub
   
   

3. Click the UserForm window to activate the UserForm.

4. Press the F5 key to run the UserForm.

NOTE: When you dismiss the UserForm, the check box will not remain on the UserForm.

To programmatically add a control to a UserForm so that it becomes part of the UserForm, you must add it during Design Time. To programmatically add a control during Design Time, do the following:

1. Working with the same project from above, click Module on the Insert menu to add a module sheet to the project.

2. In the new module sheet, enter the following code:

         Sub Design_time_control()
   
             Set x = Application.VBE.ActiveVBProject.VBComponents. _
                 Item("UserForm1").Designer. _
                 Controls.Add("Forms.CheckBox.1", "MyCheckbox", True)
   
             x.Caption = "test"
   
         End Sub
   
   

3. Place your cursor somewhere within the code you entered in Step 2.

4. Press the F5 key to run the macro.

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
