Hi there, I have a server and client application and now i want to access some records in a database. The setup i have now is that the client connects to the server using a dcom connection and then uses a clientdataset to get the data. The server has an ado connection to the database and uses ado queries to get the requested data. In between there is a dataprovider to link the clientdataset to the ado queries. This all works and i get the correct data but i have 3 problems: 1) The connection is really slow. It takes 0,3 seconds to get 1 dataset. 2) The client doesn't realise that the server is allready started and starts another server. So if my server is started in the general terminal session and a client request comes in another instance of the server executable is started. When the client isn't finished this instance also isn't closed. This is a problem propably caused by the dcom part in combination with the terminal server. 3) I can't use another ado connection in my general datamodule (outside the remote datamodule). It says then that the datasource isn't found. This isn't a big problem but it would be great if it gets resolved. Thanks in advance! With kind regards, Chris
