I'm using MIDAS for the first time and have hit a snag.

I'm following the simple MIDAS example in CPPB4 Unleashed (using CPPB4
Enterprise with Patch 1 installed). My MIDAS server has an exported
TProvider which is connected to a valid TTable, and it has been
registered.

The client uses a TDCOMConnection, and it starts the server properly
(the server is running on my local machine). It has a TClientDataset
that references the server's provider.

This is the problem: as soon as the TClientDataset's Active property is
set to true, the following error occurs:

"src->QueryInterface(GetIID(),(LPVOID*)(&intf)). No such interface
exists ..."

I know what it means, but not what's causing it. Does anyone?


Thanks...
