Overriding the Click Method on a pre-defined mmButton
Versions des environnements
We have an mmButtonCancel on most of our data entry / maintenance forms. In some cases we want to add additional functionality to the click method. I would expect that the way to do this in VB.Net would be to override the cilck method in mmButtonCancel (i.e. mmButtonCancel_Click), or the derived cancel button on the mmMaintenanceForm (i.e. mmbtnCancel). We've made several attempts but as soon as we double click on the button on the form to bring forward the code template shown below, we get an immediate error:
"Handles clause requires a WithEvents variable defined in the containing type or one of its base types."
----------
Private Sub mmbtnCancel_Click_1( ByVal sender As System.Object, ByVal e As System.EventArgs) Handles mmbtnCancel.Click
End Sub
----------
How do we get past this error and override the click method of the button?
Thanks,
Frank
