-------------------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Visual Basic Learning Edition for Windows, version 5.0 
 - Microsoft Visual Basic Professional Edition for Windows, version 5.0 
 - Microsoft Visual Basic Enterprise Edition for Windows, version 5.0 
 - Microsoft Visual Basic Standard Edition, 32-bit, for Windows, version 4.0 
 - Microsoft Visual Basic Professional Edition, 32-bit, for Windows, version 4.0 
 - Microsoft Visual Basic Enterprise Edition, 32-bit, for Windows, version 4.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

The toolbar buttons on a Toolbar control do not appear at run-time. With Visual
Basic 5.0, a Toolbar control with buttons on it appears as an empty, gray band.
With Visual Basic 4.0, the Toolbar buttons appear but the Toolbar is not tall
enough to display the captions.

CAUSE
=====

The problem occurs due to a bug in Comctl32.dll version 4.00.950 that ships with
Windows 95.

RESOLUTION
==========

Use an ImageList control to add an image to at least one button, and then all
the buttons display correctly. To resolve this problem, install any newer
version of Comctl32.dll. You can download an updated version of Comctl32.dll
from the Microsoft Download Center. See the "References" section for more
information.

STATUS
======

This problem has been corrected in later versions of Comctl32.dll.

MORE INFORMATION
================

If you do not add any images to your Toolbar buttons, the buttons may not appear
at run-time. But, if you add a ToolTip and/or code behind the button's Click
Event, these will work properly when the mouse is placed over the button's
location. Also, the gray band is taller when a Caption is used.

Steps to Reproduce Behavior
---------------------------

1. Create a Standard EXE on new installation of Windows 95 (without Internet
   Explorer installed).

2. Add a reference to the Windows Common Controls.

3. Add a Toolbar control to Form1.

4. Add the following code to Form1:

         Private Sub Form_Load()
           Dim btnX As Button
           Set btnX = Toolbar1.Buttons.Add(, , "Test", tbrDefault)
         End Sub

5. Run the Project. Note that the Toolbar appears as an empty, gray band across
   the top of the Form. It should have a single button with "Test" as its
   Caption.
