class CElemDesc
The CElemDesc class encapsulates a ELEMDESC structure.
ELEMDESC structures are part of FUNCDESC and VARDESC structures; they provide data on method parameters, method return types, and property types. See the Automation Programmer's Reference in the Platform Software Development Kit (SDK) for additional information.

| Method | Description |
| CElemDesc | Constructor. |
| AddUserDefinedData (ICreateTypeInfo *pctiDestInterface) | Adds user-defined data to the type information currently under construction. |
| Attach (ELEMDESC *pElemDesc, ITypeInfo *ptiSrc) | Attaches the CElemDesc object to an ELEMDESC structure. The ITypeInfo pointer is required only if the type of the ELEMDESC structure is VT_USERDEFINED. |
| Detach () | Detaches the CElemDesc object from the ELEMDESC structure. |
| GetArrayData (ARRAYDESC **pArrayDesc) | Returns an array descriptor for data of type VT_ARRAY. The array descriptor should point to a safe array that has a lifetime exceeding that of the CElemDesc object. If the type of CElemDesc is not VT_ARRAY, this method returns S_FALSE. |
| GetIDLDesc (IDLDESC *pIdlDesc) | Returns data in the IDLDESC structure. |
| GetName (BSTR *pbstrName) | Returns the name of an element. |
| CElemDesc *GetNext (); | Returns a pointer to the next CElemDesc object in a list. |
| GetParamdesc (PARAMDESC *pParamDesc) | Returns data in the PARAMDESC structure. |
| GetType (VARTYPE * pvt) | Returns the type of the CElemDesc object. |
| GetUserDefinedData (ITypeInfo **pptiSrc) | Returns an ITypeInfo pointer to data of type VT_USERDEFINED. The pointer is valid only within the source type information object supplied with either the constructor for the CElemDesc object or the CElemDesc::Attach method. If the CElemDesc type is not VT_USERDEFINED, this method returns S_FALSE. |
| Reset (ELEMDESC *pElemDesc) | Resets the internal ELEMDESC structure pointer to point to pElemDesc. |
| SetArrayData (ARRAYDESC *pArrayDesc) | Sets data for a member of type VT_ARRAY. Call this method after calling SetType with the type set to VT_ARRAY. The pArrayDesc must be a valid safe array descriptor with a lifetime exceeding that of the CElemDesc object. |
| SetIDLDesc (IDLDESC IdlDesc) | Sets data in the IDLDESC structure.` |
| SetName (BSTR bstrName) | Sets the name of an element. |
| CElemDesc *SetNext (CElemDesc * pNext) | Sets the next CElemDesc object in a list. |
| SetParamDesc (PARAMDESC ParamDesc) | Sets data in the PARAMDESC structure. |
| SetType (VARTYPE vt, int iIndirectionCt) | Sets the type of the CElemDesc object. Possible types are the same as those for an ELEMDESC object. Call SetType before you set any user defined data or array data. |
| SetUserDefinedData (ITypeInfo *ptiSrc) | Sets data for a member of type VT_USERDEFINED. The ITypeInfo pointer identifies the user-defined type. |
| Operator | Description |
| operator & | Copies the contents of one CElemDesc object to another. |
| operator ELEMDESC | Extracts the ELEMDESC structure from the CElemDesc object. |
