System::Boolean
true to create the first of a series of nested units; false to create subsequent nested units.
Return Value
Type: System.ComponentModel.Design::UndoEngine::UndoUnit^A new UndoEngine::UndoUnit with a specified name.
The default implementation of the CreateUndoUnit method simply returns a new UndoEngine::UndoUnit.
By default, UndoEngine does nothing with the primary parameter, but some implementations of undo, such as those involving the COM Microsoft.VisualStudio.OLE.Interop.IOleParentUndoUnit design pattern, may need to identify the difference between a primary unit and its children.
