// This project demonstrates using client datasets in an ActiveForm.
// The ActiveForm in this project works just like the client in the
// EmpEdit example.  Before compiling and using this Active Library you
// should compile and run the Srvr example from the EmpEdit project group.
//
// For information on deploying ActiveForms, look for
// "ActiveX control:and .INF file, delpolying on the web" in the online
// help index.
