Title: COM/DCOM Server - Cookbook
Question: A Cookbook or step-by-step instructions for building a DCOM server.
(Note that this is just a small cookbook - it doesn't describe things in details - it's just a first step into the topic !!)
Answer:
To build a SERVER do the following:
1. Open a project (with a form) or an ActiveX-Library if you
want a DLL.
2. Add a 'Automation Object' (File/New). Name: FIRSTSERVER
3. Add methods with the help of the type-library-editor
4. Save and run
To build the CLIENT do the following:
1. Open a Project and save it.
2. Import the SERVER_TLB.PAS via uses for early-binding.
3. Call the server:
var srv: IFirstServer;
begin
srv := CoFirstServer.Create;
srv.Method1;
srv := nil;
end;
That's it !
Some hints for the DEPLOYMENT:
1. Server.exe must be registered at the clientPC and the serverPC:
Call "TREGSVR SERVER.EXE" in the DOSBOX.
2. Start DCOMCNFG.EXE at the clientPC
- Doubleclick the Classname of the server
- Choose the machine where the server should be executed.
- Have a close look at the security.
