2.4.105 ExternName

Office

The ExternName record specifies an external defined name, a User Defined Function (UDF) reference on a XLL or COMadd-in, a DDE data item or an OLE data item, depending on the value of the virtPath field in the preceding SupBook record. If the cch field in the preceding SupBook record is 0x3A01, then this record specifies a UDF reference. Otherwise if the virtPath field in the preceding SupBook record conforms to the ole-link rule specified in the VirtualPath ABNF, then this record specifies a DDE data item or an OLE data item. Otherwise, this record specifies an external defined name.

C - fWantPict (1 bit): A bit that specifies whether this record's linked data uses a picture format. The value MUST be 0 if this record specifies an external defined name or a UDF reference on a XLL or COM add-in.

D - fOle (1 bit): A bit that, together with the value of fOleLink, specifies the structure of body. The value MUST be 0 if this record is an external defined name, an OLE data item or a UDF reference on a XLL or COM add-in. If this value is 1, fOleLink MUST be 0.

E - fOleLink (1 bit): A bit that, together with the value of fOle, specifies the structure of body. The value MUST be 0 if this record is an external defined name or a UDF reference on a XLL or COM add-in. If this value is 1, fOle MUST be 0 and this record specifies an OLE data item.

cf (10 bits): A signed integer that specifies the type of the cached clipboard format for a DDE data item or an OLE data item. The value MUST be 0 if this record is an external defined name or a UDF reference on a XLL or COM add-in. The value MUST be one of the values in the following table:
