The information in this article applies to:

- Microsoft Visual Basic Learning Edition for Windows, version 6.0 
- Microsoft Visual Basic Professional Edition for Windows, version 6.0 
- Microsoft Visual Basic Enterprise Edition for Windows, version 6.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

An ImageCombo control on an MDIForm initially appears empty. Even when an item
is selected from the drop-down list it does not display any images.

CAUSE
=====

When on an MDIForm, the ImageCombo does not initially bind to its ImageList nor
does it display its text. So the image(s) does not appear if the ImageList
property of the ImageCombo was set at design-time.

RESOLUTION
==========

To make the image(s) appear, set the ImageList property of the ImageCombo at
run-time when on an MDIForm. To make the text display, set the focus to the
ImageCombo. Note that making the ImageCombo's TabIndex = 0 will not work.

STATUS
======

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

This bug was corrected in Visual Studio 6.0 Service Pack 3.

Steps To Reproduce
------------------

1. Create a Standard EXE project in Visual Basic. Form1 is created by default.

2. Select Components from the Project menu, select Microsoft Windows Common
  Controls 6.0," and click OK.

3. Add an MDIForm, MDIForm1, to the project.

4. Choose Properties from the Project menu and make MDIForm1 the Startup Object.

5. Place a PictureBox onto MDIForm1.

6. Place an ImageList control and an ImageCombo into the PictureBox.

7. Alternate-click on ImageList and select Properties. Select the tab and insert
  an image into the ImageList.

8. From the Custom Properties of the ImageCombo, set the ImageList property to
  ImageList1.

9. Place the following into the MDIForm's module:

        Private Sub MDIForm_Load()
           ImageCombo1.ComboItems.Add , "Key1", "Test", 1, 1
           ImageCombo1.SelectedItem = ImageCombo1.ComboItems(1)
        End Sub

10. Run the project and note that the ImageCombo is initially blank.

11. Try to pick the item from the list. Note that at no time does the image
  appear, but the Text appears after the list has been dropped.

12. Close the project.

13. Change the code above (from step 9) to the following:

        Private Sub MDIForm_Load()
           ImageCombo1.ImageList = ImageList1   ' set ImageList at run-time
           ImageCombo1.ComboItems.Add , "Key1", "Test", 1, 1
           ImageCombo1.SelectedItem = ImageCombo1.ComboItems(1)
           Me.Show  ' Show now rather than after this event finishes
           ImageCombo1.SetFocus  ' This makes the Text appear
        End Sub

14. From the properties window of the ImageCombo, set ImageList to <None>.

15. Run the project and note that the image and text now immediately appear in
  the ImageCombo.
