System::OleVariant is a special descendant of the Variant class that is used to represent COM interfaces or data that is passed over a COM interface. System::OleVariant inherits from Variant as a protected class so that it can prevent operations on AnsiString objects, which are not compatible with COM.. The syntax for using System::OleVariant is the same as that for using the Variant class.

One explanation is that OleVariant holds the entire string but that you are looking at the debugger tooltip. In older Delphi versions the debugger tooltip truncates at characters for strings held in a variant. Note that the debugger tooltip for a plain string does not truncate at this length. Try showing the variant in a dialog box and you will see that the entire string is present.

The syntax for using System::OleVariant is the same as that for using the Variant class. I have inherited an old Borland C++ Builder application which I now must migrate to a new development tool. The suggested way to go is with Embarcadero C++ Builder, and from my initial tests it seems AnsiString as default for type string in Embarcadero C++ Builder? Importing an Embarcadero C++ Builder XE3 DLL into Embarcadero C++. CreateOleObject creates a single uninitialized object of the class specified by the ClassName parameter. ClassName specifies the string representation of the Class ID (CLSID). CreateOleObject is used to create an object of a specified type when the CLSID is known and when the object is on a local or in-proc server. I used to forget about the difference between Variant and OleVariant, and used them like this: Use OleVariants for OLE, and Variants for non OLE. There is no need to manually clear them.
