PRB: Align Property Setting Causes Toolbar to Fill the Form

• Standard, Professional, and Enterprise Editions of Microsoft Visual Basic, 16-bit and 32-bit, for Windows, version 4.0

SYMPTOMS

When you change the align property to the left or right position, the control's width stays the same, the height changes to the height of the form, and the control becomes aligned with the desired side.

CAUSE

This is by design. All controls that have an align property behave like This. This includes the 3D panel, ProgressBar, StatusBar, and Toolbar controls.

The toolbar control's default align setting is top, so in this case, the toolbar's width is the width of the form. When you change the align property to the left or right, the width stays the same (form's width), and the height becomes equal to the form. As a result, the toolbar takes up the entire form.

RESOLUTION

To work around this in code, you must set the width or height to the values you want when you change the align property. In addition, You might want to change the toolbar's BorderStyle property to 1-fixed single to make the toolbar border more visible.

STATUS

This behavior is by design.

MORE INFORMATION

Steps to Reproduce Behavior

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

2. Add a command button and a toolbar to Form1.

3. Place the following code in the command button click event:

      Private Sub Command1_Click()
         If Toolbar1.Align < 4 Then
            Toolbar1.Align = Toolbar1.Align + 1
         Else
            Toolbar1.Align = 0
         End If
      End Sub
   
   

4. Change the toolbar's BorderStyle property to 1-fixed single.

5. Run the program, and click the command button twice. The toolbar moves from top to bottom. Then it moves from bottom to the entire screen. All the other controls on the form are hidden from view.
