Hello,
I am trying to access the COM object implemented by the remote data module.
Borland Help
says that
 AppServer property of the TRemoteServer returns the interface pointer and
gives an example.

IMyObjectDisp AnObject(LPDISPATCH(MyRemoteServer->AppServer));

AnObject->DoSomething();

However this coude does not even compile. I tried to cast it to the
IMyObject and the call DoSomething however
I get an Access Violation..
Does anybody has a sample code that works correctly.

Thanks

I have made just what you are talking about.  Here is a snip of my
code.

I have made a method on the com interface that is called QuerySet.
This will set the SQL area of a TQuery component

try
               {
               DCOMConnection->Connected = true;
               }
           catch(...)
               {
               ShowMessage("Unable to Connect to the Remote Server!");
               ClientDataSet->Active = false;
               DCOMConnection->Connected = false;
               return;
               }
        IDispatch* disp = (IDispatch*)(DCOMConnection->AppServer);
        IMyObjectDisp MyObject((IMyObject*)disp);
        String SQL = "SELECT * from WhatEver";
        MyObject.QuerySet(WideString(SQL).Detach());
        ClientDataSet->Active = true;

After I set the SQL in the TQuery Component I then Activate the
ClientDataSet.

Hope this helps.
