| Features and Techniques > Using True DataControl in Different Containers > The NameSubstitute Property Must Be Used in VC++ |
Using True DataControl in VC++, you have to set its NameSubstitute property at design time. Set this property to the control name, what would be its Name property value in Visual Basic. This property is necessary because VC++ container does not supply its own Name property. True DataControl relies on Name for master-detail relationships.
