VBA Code Stops Working

The following code is called everytime the form is opened. It works great until the 5th opening and then mi开发者_如何学编程sses deleting one of the controls. Anyone know why this is?

 For Each cb In Forms(frmName).Controls
     If cb.ControlType = acCheckBox Then
         If Left(cb.Name, 3) = "clr" Then
            DeleteControl frmName, cb.Name
         End If
     ElseIf cb.ControlType = acLabel Then
         If Left(cb.Name, 3) = "clr" Then
            DeleteControl frmName, cb.Name
        End If
     End If
 Next

When you delete an item from a collection in Access the next item moves into that items spot. Thus when it comes to deleting items from a collection you must start at the end of the collection and go backward.

So replace the

For Each cb In Forms(frmName).Controls

line with

For counter = Forms(frmName).Controls.Count - 1 To 0 Step -1
set cb = Forms(frmName).Controls.Item(counter)

My next question though is what is your overall objective? It's unusual to be manipulating controls in design view programmatically.
