Using: Borland C++Builder v3.0

I cannot seem to be able to set the Port property of a TServerSocket at 
runtime as follows:

  ServerSocket1->Port = MyPort;

I get a link error:

[LinkerError] Unresolved external 'Scktcomp::TAbstractSocket::SetPortA(int) 
__fastcall' referenced from D:\JON\CHARTINGTEST\GUI.OBJ.

Yes, I know I should be using a newer version of _everything_.

Am I missing something here? Is there an easy fix for this? I've looked at 
the source, but a cure isn't jumping out at me. Alternatively, is there a 
better socket component that is simple and lite like TServerSocket that I 
could use in C++Builder v3.0?

That is a long-standing problem caused by Microsoft's headers, not the
VCL's.  This is documented on Borland's website:

    How do I get rid of the unresolved external to SetPortA when using
Socket components?

Thanks - worked like a charm. I just moved the ScktComp.hpp header file up 
to the top of the list. No more link problems.
