Hello! As a self-taught casual programmer, i'm having a bit of trouble with Delphi 3. I'm trying to play about with the TCP demo application. It works fine on my machine but when I try it other pc's I get the following error:

Exception EOleSysError in module DCHAT.EXE at 00032EF9. Class not registered.

I think its got something to do with setting up ActiveX and STDVCL32.dll but other than this I'm totally stuck! Any help would be greatly apreciated.

Cheers,
Tarquin

The demo is using the NetManage Internet Controls which are wrappers to ActiveX controls. Since they don't exist on a machine without Delphi installed, you need to copy and register the ActiveX server.

The file is located in your windows SYSTEM or SYSTEM32 directory and is called WINSCK.OCX. You can also find it on your Delphi CD in the RUNIMAGE\DELPHI30\WINDOWS\SYSTEM32 folder. Copy this file to the windows SYSTEM or SYSTEM32 folder.

After you copy the file, type "REGSRVR32 C:\WINDOWS\SYSTEM\WINSCK.OCX" or "REGSRVR32 C:\WINNT\SYSTEM32\WINSCK.OCX" at the command prompt.

Cheers! Are the NetManage Internet Controls okay, or is there a better set of controls out there? [ideally freeware]

um, that doesn't work. I get the following error:

"LoadLibrary("winsck.ocx")
failed GetLastError returns 0x00000485"

Cheers!

I see that others have given you some pretty good help, but I'll toss out a couple more ideas...

>nmocod.dll,nmsckn.dll,nmorenu.dll
>Anyone know the status on distributing these and the ocx?

Ah, NetManage and Delphi 3! That takes me way back some years. I fondly remember D3 as one of the "great" Delphi releases.

Since the prefix on each of those DLLs is "nm," I suspect they're part of the NetManage suite of goodies, and you should be fine deploying them along with the OCX.

Somebody asked if there were better components than NetManage.  Well, in my opinion, yes.  I'm very fond of the Indy Sockets components for TCP/IP communication:
http://www.indyproject.org/index.en.aspx

The thing is, I'm not sure Indy supports Delphi 3.  Delphi 4 is mentioned on their Downloads area.

One nice thing about Indy is that there are no DLLs or OCXs to deploy along with your application. The Indy code compiles right into your application.

One more thing: If you're going to deploy your program on other machines, and if it has dependencies on other files, I highly recommend that you deploy via a setup program. There are many free - and commercial - installation building programs.  My favorite happens to be free.

It's Inno Setup:
http://www.jrsoftware.org/isinfo.php

While you're downloading that, be sure to grab a copy of ISTool:
http://www.jrsoftware.org/isinfo.php

ISTool is also free, and provides a nice GUI for Inno Setup. Between the two, you have a killer install making toolkit.
