Hi all ,

I am a new hand to write a multi-tier program. So please help me.
My question descriptes below.
In my RDM, I create a method and it is decleared like
   THODIMP TRDMImpl::GetIndex(TVariantInParam vSymbol,  TVariant* vIndex)

In my client I call this method
   TDCOMConnection *DCOM;
   String sSymbol, sIndex;

   DCOM->AppServer.Exec(Function("GetIndex")<<sSymbol<<&sIndex);
Before executing this statement, I have done the initialize include new the
object, set the property Connect to true.
I know in the Server the vIndex has value, but in client the sIndex has no
value (=NULL).
Anybody can tell me how to get the value from Server by GetIndex.

Your early reply is highly appreciated.

Thanks all.
