IDispatchEx::GetMemberProperties

Retrieves a member's properties.

HRESULT GetMemberProperties(
   DISPID id,
   DWORD grfdexFetch,
   DWORD *pgrfdex
);

Returns one of the following values:

Parameters

id

Identifies the member. Uses GetDispID or GetNextDispID to obtain the dispatch identifier.

grfdexFetch

Determines which properties to retrieve. This can be a combination of the values listed under pgrfdex and/or a combination of the following values:

Value	Meaning
grfdexPropCanAll	Combines fdexPropCanGet, fdexPropCanPut, fdexPropCanPutRef, fdexPropCanCall, fdexPropCanConstruct and fdexPropCanSourceEvents.
grfdexPropCannotAll	Combines fdexPropCannotGet, fdexPropCannotPut, fdexPropCannotPutRef, fdexPropCannotCall, fdexPropCannotConstruct and fdexPropCannotSourceEvents.
grfdexPropExtraAll	Combines fdexPropNoSideEffects and fdexPropDynamicType.
grfdexPropAll	Combines grfdexPropCanAll, grfdexPropCannotAll and grfdexPropExtraAll.

pgrfdex

Address of a DWORD that receives the requested properties. This can be a combination of the following values:

Value	Meaning
fdexPropCanGet	The member can be obtained using DISPATCH_PROPERTYGET.
fdexPropCannotGet	The member cannot be obtained using DISPATCH_PROPERTYGET.
fdexPropCanPut	The member can be set using DISPATCH_PROPERTYPUT.
fdexPropCannotPut	The member cannot be set using DISPATCH_PROPERTYPUT.
fdexPropCanPutRef	The member can be set using DISPATCH_PROPERTYPUTREF.
fdexPropCannotPutRef	The member cannot be set using DISPATCH_PROPERTYPUTREF.
fdexPropNoSideEffects	The member does not have any side effects. For example, a debugger could safely get/set/call this member without changing the state of the script being debugged.
fdexPropDynamicType	The member is dynamic and can change during the lifetime of the object.
fdexPropCanCall	The member can be called as a method using DISPATCH_METHOD.
fdexPropCannotCall	The member cannot be called as a method using DISPATCH_METHOD.
fdexPropCanConstruct	The member can be called as a constructor using DISPATCH_CONSTRUCT.
fdexPropCannotConstruct	The member cannot be called as a constructor using DISPATCH_CONSTRUCT.
fdexPropCanSourceEvents	The member can fire events.
fdexPropCannotSourceEvents	The member cannot fire events.

Example

BSTR bstrName;
   DISPID dispid;
   IDispatch *pdex; 
   DWORD dwProps;
   // Assign to pdex and bstrName
   pdex->GetDispID(bstrName, fdexNameCaseSensitive, &dispid);
   pdex->GetMemberProperties(dispid, grfdexPropAll, &dwProps);
   if (dwProps & fdexPropCanPut)
      // Assign to member
