I have button on my form that uses a selected record in a listbox (non multi-select) to run code that updates a table. The code itself works great so long as there is a record selected in the listbox. If no record is selected an error is thrown. I'd prefer the end user not to ever see that error. If the end user clicks the button and no records are selected, I'd like for nothing to happen at all. I've tried several variations of checking the listbox with an if / then statement to see if records are selected and if so to exit sub, but they all throw errors when no record is selected in the listbox.
Code:
If IsNull(Me!lstHeatTreatments) Then
Exit Sub
End If
Code:
If IsNull(Me.lstHeatTreatments) Then
Exit Sub
End If
Code:
If Me.lstHeatTreatments.Selected = False Then
Exit Sub
End If
