SUMMARY

This article describes how to use the Toolbar control in the 32-bit version of Visual Basic 4.0 to allow programmers to add buttons to the Toolbar but not ComboBoxes. If you create a ComboBox at design time and place it on top of the Toolbar, the ComboBox will not appear when the program is run. This behavior occurs because the Toolbar has a higher precedence than the ComboBox on the Z-order.

To put a ComboBox on a Toolbar, create a button on the Toolbar to act as a place holder, and position the ComboBox above the place holder in the Z-order, because you cannot place the ComboBox inside the place holder directly.

The following code sample showing how this effect can be achieved.

MORE INFORMATION

Start a new Visual Basic project. Form1 is created by default.
Place a ComboBox on the form.
Place a Toolbar on the form.

Add the following code to the Form1 code window:

   Option Explicit

   Private Sub Form_Load()
      Dim btn As Button
      Me.Show
      Set btn = Toolbar1.Buttons.Add()
      btn.Style = tbrSeparator
      Set btn = Toolbar1.Buttons.Add()
      btn.Style = tbrPlaceholder
      btn.Key = "ComboBox"
      btn.Width = 2000

      DoEvents

      With Combo1     
         .ZOrder 0
         .Width = Toolbar1.Buttons("ComboBox").Width
         .Top = Toolbar1.Buttons("ComboBox").Top
         .Left = Toolbar1.Buttons("ComboBox").Left
      End With
   End Sub

Press the F5 key to run the project. The Form should load with a ComboBox in the Toolbar.
