In your example UDTVariable1 is declared but never used, and TreaderParty is
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....

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.

This is part of your header. Does your IDL compile fine?
Could it be just a typo in the struct name compared to your
IDL file?
As far as Brian's concern about Automation-compatibility,
you can check this FAQ article if Automation is a concern
for you too:

Hi All,
I want to pass a structure in my ATL function. On defining signatures
of the ATL function i am getting this error
error MIDL2025 : syntax error : expecting a type specification near
"TreaderParty"
These are the signature i declared for my function
STDMETHOD(MakeCall)(/*[in]*/ TreaderParty TTreaderParty, /*[out,
retval]*/ BSTR**bstrArr);
Any help ...
Regards,
Rachana
