These examples come from HFG's interrogation of Microsoft's Northwind sample database.

  

It can be seen that the name of the control is ctlPageNumber, which should be a Text Box, but these are Lines and the Rectangle should not be there at all, but it has been given the same name as the Lines.

The example below shows a Rectangle again getting mixed in with Text Box Types.

It must be said that these examples are from the Northwind database Reports and the naming here is not as critical as on Forms but one should strive to do better.
