    Hello,

    I need to make COM IntetrOp at runtime using reflections. My native COM Object's exposed methods have some parameters as pointers (DWORD*) and some double pointers (DWORD**) and some are user defined types(e.g SomeUDTType objSmeUDTType) and its pointer to pointer(i.e. SomeUDTType **pSomeUDTType).

    I need to pass pointers to pointers. For now how can I be able to populate "object" array as pointers to pointers of SomeUDTType.

    Native COM exposed method :

    STDMETHODIMP MyCallableMethod(DWORD *value_1,BSTR *bstrName,WESContext **a_wesContext

    tlbImp generated output:

    DTINIDLLib.RuntimeCallingClass.MyCallableMethod(ref uint, ref string, System.IntrPtr)


    Regards
    Usman
