Using MapX With CBuilder 4
In addition to the material in Using MapX With CBuilder 3...
-
In any places referring to MFC CMap... types, change them to ::CMap... because the type library now exports these types, though they are not MFC classes in the export.
-
Include file MapXLib_TLB.h is now MapXLib_OCX.h
-
MapXDisp is now CMapXDisp.
-
The RequestData closure signature is now
void __fastcall RequestData(System::TObject * Sender, BSTR DataSetName, long Row, short Field, TVariant* Value, TOLEBOOL* Done)rather thanvoid __fastcall RequestData(TObject *Sender, BSTR DataSetName, long Row, short Field, tagVARIANT *Value, VARIANT_BOOL *Done); - Those pesky underscores in some property names (like Datasets_) are now gone.
