Visual basic . NET!
This occurs with some code as follows:
[code]
Private Sub button7_Click_1(ByVal sender As Object, ByVal e As EventArgs) Handles button7.Click
' do some stuff
End Sub
[/code]
instead you need to add a line above it, so completed it shall read as :
[code]
Public WithEvents button7 As Button
Private Sub button7_Click_1(ByVal sender As Object, ByVal e As EventArgs) Handles button7.Click
'do some stuff
End Sub
[/code]
Now remember if the end of the private sub says Handles cboStuff.SelectedIndexChange or some stuff, you need to declare the withevents as
Public WithEvents cboStuff as ComboBox
Hope it helps.
