FIX: Form Move Event Can Generate Error Message

ID: Q180767

The information in this article applies to:

SYMPTOMS

When the Move method of a form or control is used without all of the parameters, one of the following error messages is generated:

An error was encountered while running this program.
-or-
Wrong number of arguments or invalid property assignment.


RESOLUTION

The workaround is to use all of the parameters of the Move method.


STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article.

This problem was corrected in Windows CE Toolkit for Visual Basic 6.0.


MORE INFORMATION

Steps to Reproduce Behavior

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


  2. Add the following code to the Form1 code module:
    
      Private Sub Form_Load()
         On Error Resume Next
         Form1.Width = 200 * Screen.TwipsPerPixelX
         Form1.Height = 100 * Screen.TwipsPerPixelY
         'Center Form on screen
         Form1.Move (Screen.Width - Form1.Width) \ 2, _
            (Screen.Height - Form1.Height) \ 2
         'Display error information
         If Err.Number <> 0 Then
            MsgBox "Error: " & Err.Number & " - " & _
               Err.Description, vbInformation, "Error Message"
         End If
      End Sub


  3. Press the F5 key to run the project. A message box appears with the message "Error 450: Wrong number of arguments or invalid property assignment." NOTE: By trapping the error message, a more descriptive message can be displayed. Otherwise, the message "An error was encountered while running this program" appears.
