TComponent.GetTypeInfoCount Method

Returns the number of type information interfaces that an object provides (either 0 or 1).

function GetTypeInfoCount(out Count: Integer): HResult; stdcall;
__fastcall __stdcall HRESULT GetTypeInfoCount(int Count);

GetTypeInfoCount implements the IDispatch interface GetTypeInfoCount method. For components that support interfaces, GetTypeInfoCount calls this method for the interface supported by the component. The Count parameter points to a location that receives the number of type information interfaces provided by the object. If the object provides type information, this number is 1; otherwise the number is 0.
