Macro Substitution in VB?

Your best bet will probably be to use a control array.  Name all your controls LED and set their index (0, 1, etc)

Make your sub

Sub Change_LED_To_Green(Index as Long)
  frmMain.LED(Index).LoadPicture("C:\Images\Green.Gif")
End Sub

I hate it when that happens :)

I know the feeling.

Alternatively you could enumerate the controls on the form looking for the appropriate one. e.g.

Sub Change_LED_to_Green(ControlName As String)

    Dim c As Control
    For Each c In frmMain.Controls
        If c.Name = ControlName Then
            Call c.LoadPicture ("C:\Images\Green.gif")
            Exit Sub
        End If
    Next c

End Sub

Actually you can do it like this:

     Sub Change_LED_to_Green(ControlName As Object)
         ControlName.LoadPicture ("C:\Images\Green.gif")
     End Sub

Then whenever you want to change a controls color to green you can just call:


     Change_LED_to_Green LED1


Hope this helps...

Cheers!??

Call Change_LED_to_Green("LED_1")
...
...
...
Sub Change_LED_to_Green(ControlName As String)
frmMain.Controls(ControlName).LoadPicture("C:\Images\Green.gif")
End Sub
