Title: I'm having issues closing AHMI after I add new pages
Post by: pretengineer on April 03, 2025, 04:29:33 PM

The new page opens fine and everything works. The ReturnToMain button is working fine. But when I close the main form it breaks. This doesn't happen on the default Page2, only the one I added.

The part that is breaking is this (line highlighted). I've copied the code to the new page like it says to do. It all works fine until I start adding drivers so I think that's where the issue is but I can't figure out how to correct.

#Region "Constructor/Destructor"
    '****************************************************************
    '* UserControl overrides dispose to clean up the component list.
    '****************************************************************
    Protected Overrides Sub Dispose(ByVal disposing As Boolean)
        Try
            If disposing Then
                If SubScriptions IsNot Nothing Then
                    SubScriptions.dispose()
                End If
            End If
        Finally
            'V3.99p - added Try-Catch
            Try
                MyBase.Dispose(disposing)
            Catch
            End Try
        End Try
    End Sub
#End Region

That Try-Catch was added there to basically ignore the exception since it happens when the app is closing. You may have changed something to tell VS to break on all CLR exceptions.

In Visual Studio go to Debug->Windows->Exception Settings (Ctrl+Alt+E)
When the Exception Settings window opens, right click in it and select Restore Defaults.
