Re: Want to pass a structure in my ATL function call

Hi Alexander,

Yes initialy I declared the Structure in the header file but that
should be declared in the idl file. After the declartion of Structure i
am getting these errors
********************
error MIDL2096 : duplicated attribute : [helpstring] [ Type
'UDTVariable1' ( Interface '__MIDL_itf_Structure_0209' ) ]

********************
This is my idl file....
*******************************************************

// Structure.idl : IDL source for Structure.dll
//

// This file will be processed by the MIDL tool to
// produce the type library (Structure.tlb) and marshalling code.

import "oaidl.idl";
import "ocidl.idl";

    [
        object,
        uuid(CABFB498-2561-47C9-A991-BBF98A8C7331),
        dual,
        helpstring("Imyclass Interface"),
        pointer_default(unique)
    ]
    interface Imyclass : IDispatch
    {

// [id(1), helpstring("method MakeCall")] HRESULT MakeCall(/*[in]*/
TreaderParty TTreaderParty, /*[out, retval]*/ BSTR**bstrArr);
    };

[
    uuid(3BE26CA5-53C4-4542-AD7A-378D0B416FB5),
    version(1.0),
    helpstring("Structure 1.0 Type Library")
]

 typedef
    [
        uuid(84D5D628-EFFD-4274-8627-2275DC8315E0),
        version(1.0),
        helpstring("A Demo UDT variable for VB projects")
    ]
    struct UDTVariable {
        [helpstring("Special case variant")] BSTR Special;
        [helpstring("Name of the variable")] BSTR Name;
        [helpstring("Value of the variable")] long Value;
    } UDTVariable1;

library STRUCTURELib
{
    importlib("stdole32.tlb");
    importlib("stdole2.tlb");

    [
        uuid(84D5D628-EFFD-4274-8627-2275DC8315E0),
        helpstring("myclass Class")
    ]
    coclass myclass
    {
        [default] interface Imyclass;
    };
};

Might be i am doing something wrong in the declartion of the Structure.
Please tell me the cause and the solution to get rid with this problem.
