How can I override a handler for a Form ControlBox

How can I override a handler for a Form ControlBox

• Jim Ransford

  In Pocket PC applications, you either have an Minimize (X) or a Close (OK) button in the upper right corner. Minimize is the default, which keeps the application running in the background. You can change the X to OK by doing adding the following line to the Form's constructor or InitializeComponent() method:
  
  
  
  ' Change Minimize (x) to Close (ok)
  
  Me.MinizeButton = False
  
  
  
  To override the Closing event, add this method to your Form:
  
  
  
  Private Sub Form1_Closing(sender As Object, e As System.ComponentModel.CancelEventArgs) _
  
  Handles MyBase.Closing
  
  MsgBox("Closing App")
  
  ' do stuff
  
  End Sub

  What device are you targeting Only custom WinCE devices show you all controlbox elements; PPCs have either an "X" or an "OK" in the top right corner which you can control with the MinimizeBox property.
  
  See if handling the Closing/Closed events gets you where you want to be.

  I got this to work but the property name is:
  
  Me.MinimizeBox = False
  
  Probably the confusion is that "X" means close in Windows XP but Minimize in the mobile O.S., in my case I am using CE 5.0. So obviously the Closed event is not raised when the window is minimized, even though the X intuitively should be "close". Instead, "ok" means close. Just my two cents.
