    Setting focus

    I have a form containing a tab control
    I want focus set to a particular text box when the form opens.

    However doing this in the load form event
    If TabControl1.Sel ectedIndex = 0 Then
    If txtFileName.Can Focus Then
    txtFileName.Foc us()
    End If

    End If
    I get false from canfocus.

    I can do it fine in the tabcontrol.sele ctedindexchange d event so why
    can't I do it in load?

    Thanks

      Controls have not necessarily completed their initilization in the
      form's load event. A control to receive the focus, must be enabled,
      visible, and have a handle. You may want to move this code to the forms
      activated event - though, you will want to put a flag to make sure this
      only happens the first time the activated event fires.

      You might also make this happen if you do something like:

      Me.Visible = True
      Me.Refresh
      If txtFileName.Can Focus Then
      txtFileName.Foc us ()
      End If

      In your load event. This will force the form to become visible and
      redraw it self....
