BUG: Setting Value Property of Toolbar to Zero Clears Button

MORE INFORMATION

Within a button group, one button and only one button should remain checked at all times. If another button is checked, the first button becomes cleared.

The only way to clear a button that is member of a button group is to check another member of that group.

This is the expected behavior.

Steps to Reproduce the Problem

1. Start Visual Basic, or on the File menu, click New Project (ALT, F, N).
2. Add a toolbar.
3. From the Toolbar Properties window, click the Custom property. Click the button to display the Toolbar Control Properties dialog box.
4. In the Toolbar Control Properties dialog box, select the Buttons tab.
5. Insert four buttons, each having a style of "Button Group."
6. Click OK to exit the Toolbar Control Properties dialog box.
7. Press F5 to run the application.
8. Click the various buttons and observe the selection behavior. Only one button is depressed at a time. You cannot clear a button that has been depressed.
9. Click CTRL+BREAK to halt the program.
10. Type the following code in the debug window:

           Toolbar1.Buttons(x).value=0  'where x = button # that is depressed
    						

    The result is that all buttons are now cleared.
