I am using the CBuilder4, patch#1.

I created a multitier app, registered successfully, but when i try to
connect the ClientDataSet to the provider, i get an error message "no such
interface supported".

I read some messages that there is a problem in the new patch of the
CBuilder4, so i reinstalled the original version and it works FINE.

In fact i need the patch, becase other problems are solved.

Others suggested to replace the definition "IProviderPtr" with IProvider*,
but when i do that, other compile error apears.

If someone  already solved the problem, in the patch#1, please send me a
message

Best regards

It sounds like dbclient.dll is not present on the server, or that it has not
been registered. Copy dbclient to the server's winnt\system32 directory, and
run regsvr32 on it. You should do the same thing to stdvcl40.dll.

For debugging, you may want to test the server and the client on the server
machine.

In fact its a BUG in the SP1 of the CBuilder , the code that is generated in
the Implementation DataModal :

  *Value = IProv
should be :
 *Value = (IProvider *) IProv
