PRB: LostFocus of Textbox Control Has Different Behavior

• Microsoft Visual Basic Professional and Enterprise Editions for Windows, versions 4.0, 5.0, 6.0

SYMPTOMS

In Visual Basic version 4.0, when a TextBox control has focus and a toolbar is clicked, the LostFocus event of the TextBox is executed. Visual Basic 5.0 and later does not behave the same way and the LostFocus event is not executed.

RESOLUTION

The toolbar is behaving similar to a menu, which is more appropriate.

Do not use a toolbar, in Visual Basic version 5.0, if you want the LostFocus event of the TextBox control executed when the toolbar is clicked.

Instead, have a CommandButton control on the form if executing LostFocus is important to the applications design.

STATUS

This behavior is by design.

MORE INFORMATION

Steps to Reproduce Behavior

1. Create a Standard EXE project with 1 form. Add Microsoft Common Controls by clicking Components on the Project menu.



2. Place a toolbar on the form.



3. Add a TextBox control to the form and place one button on the toolbar by right-clicking the toolbar and clicking Properties.



4. Place a MsgBox command in the textbox LostFocus event:

   
         MsgBox "LostFocus Event of TextBox Control" 




5. While the textbox has focus, click the Toolbar control. Note that Visual Basic version 4.0 displays the MsgBox, while Visual Basic version 5.0 does not.
