You can learn how to use CExtGridCellVariant cells from the ProfUIS_Controls and SimpleGrids samples.

The VARIANT data structure is defined in OLE Automation API. That is why we used this type as is. The COleVariant class in the MFC library and the CComVariant class in the ATL library are designed as wrapper classes with additional functionality which we don’t need. Our CExtGridCellVariant grid cell class has the VARIANT data structure in the list of base class members and includes all the required APIs for using the VARIANT’s internal data formats as data of grid cell. So you should be able to assign any objects of wrapper classes around VARIANT data structure from our VARIANT-based grid cell objects. Besides our CExtGridCellVariant grid cell class includes support for 64-bit numeric types on old Windows OS versions and additional helper APIs which are needed for using VARIANT data inside grid cells.
