Using dispatch interfaces with TCP/IP or HTTP When you are using TCP/IP or HTTP, you can't use true early binding, but because the remote data module uses a dual interface, you can use the application server's dispinterface to improve performance over simple late binding. The dispinterface has the same name as the remote data module's interface, with the string 'Disp' appended. You can assign the AppServer property to a variable of this type to obtain the dispinterface. Thus:
var TempInterface: IMyAppServerDisp; begin TempInterface :=IMyAppServerDisp(IDispatch(MyConnection.AppServer)); ... TempInterface.SpecialMethod(x,y); ... end;
Note
To use the dispinterface, you must add the _TLB unit that is generated when you save the type library to the uses clause of your client module.
