HOWTO: Center a Form in the Windows CE Toolkit for VB5

• Microsoft Windows CE Toolkit for Visual Basic 5.0

SUMMARY

This article describes how to center a form in the Windows CE Toolkit for Visual Basic 5.0 (VBCE).

MORE INFORMATION

To center a form in VBCE 5.0, use the Move method of the Form to reposition it on the screen.

The following example shows how to create a reusable routine that can be used to center any form in your project:

1. Create a new Windows CE project in Visual Basic 5.0. Form1 is created by default.



2. Size the form so that it will be somewhat smaller than the HPC screen.



3. From the Project menu, click Add module.



4. In the Module, add the following code:

   
         Public Sub CenterForm(Frm)
             'Do not try to use 'me' for the form reference (Frm).
             On Error Resume Next
             'Do not resize if Minimized or Maximized.
             If Frm.WindowState = 0 Then
                 Frm.Move (Screen.Width - Frm.Width) \ 2, _
                     (Screen.Height - Frm.Height) \ 2, _
                     Frm.Width, Frm.Height
             End If
   
         End Sub 




5. In the Form_Load event of the form, call the CenterForm procedure as follows: (Unlike regular Visual Basic, the 'Me' keyword cannot be used to refer to the form.)

   
         Private Sub Form_Load()
             CenterForm Form1
         End Sub 




6. Run the project, and note that when the form loads it is centered on the screen. Also note that VBCE 5.0 is unable to determine the height of the Windows CE taskbar. Therefore, the VBCE form is centered according to the metrics based on the full screen size.
