LinkNotify Event Example

The example is attached to a picture box control, Picture1, which has its LinkMode property set to 3 (Notify) and its LinkTopic and LinkItem properties set to specify picture data in the source.  When the source changes this data, the procedure updates the picture box immediately only if the picture box is on the active form (the form that has the focus); otherwise it sets a flag variable.  The example is for illustration only.

Sub Picture1_LinkNotify ()

   If Screen.ActiveForm Is Me Then

   Picture1.LinkRequest      ' Picture is on active form, so update.

   Else

      NewDataFlag = True     ' Assumed to be a module-level variable.

   End If

End Sub
