BUG: Toolbar Displays Multiple Selected Toggle Buttons

MORE INFORMATION

This problem occurs whenever the Value property of one of the toggle buttons is set to "1 - tbrPressed" before the control is first displayed on the screen at run-time. For example, setting this property at any of the following times will result in this problem:

1. Design time.
2. Form's Initialize event.
3. Form's Load event.

Despite the appearance of these buttons, only the last button selected actually has its Value property set to "1 - tbrPressed." All other toggle buttons within this toggle group have their Value property correctly set to "0 - tbrUnPressed."

Steps to Reproduce Behavior

1. Create a new Standard EXE project. Form1 is created by default.
2. Select Components from the Project menu and add a reference to the "Microsoft Windows Common Controls 6.0."
3. Add a Toolbar control to Form1.
4. View the custom property sheet for the Toolbar control, select the Buttons tab, and insert two buttons.
5. Set the Style property of both buttons to "2 - tbrButtonGroup."
6. Set button 1's Value property to "1 - tbrPressed" and leave button 2's Value as "0 - tbrUnPressed."
7. Paste the following code into Form1's code window:

          Private Sub Form_Click()
             Toolbar1.Buttons(2).Value = tbrPressed
          End Sub
   						

8. Run the sample project.
9. Click on the form, and note that both Toolbar buttons appear to be pressed.

WORKAROUND

1. Add a Timer control to Form1 in the previous project.
2. Set the Timer's Interval property to "1."
3. Add the following code to Form1:

          Private Sub Timer1_Timer()
             Toolbar1.Buttons(1).Value = tbrPressed
             Timer1.Enabled = False
          End Sub
   						

4. View the custom property sheet for the Toolbar control. Set the Value property of all Toolbar buttons to "0 - tbrUnPressed."
5. Run your sample and click on Form1. Note that the Toolbar's correct appearance is achieved.
