referencing form control labels in VBA

I need to hide the labels on a sheet if a certain cell has a specific value. The labels are not activeX labels, but are the form control labels. I know how to loop through activeX controls. See code below. But how do I code this for the form control label?

   For Each OleObj In ActiveSheet.OLEObjects
      If OleObj.progID = "Forms.Label.1" Then
         OleObj.Object.Visible = False
      End If
  Next OleObj
