I posted a meesage today (Problems with a TClientDataSet at 9:57).
I could resolve the that problem, but now I have another one:

The client cannot connect with the server, there is a message like this:

'scr->QueryInterface(GetIID(),(LPVOID*)(&intf))'. this interface is not
possible @c:\...\INCLUDE\VCL\utilcls.h/1024

I use a TDCOMConnection in the client and a TDataSetProvider in the
server.

Juan,

All of the providers on the server have a function get_<provider name>.
In every one of those functions you will have to change:
  *Value = IProv;
to:
  *Value = (IProvider *)IProv;

HTH,
Steve Pietrykoski
