I am using a TTcpClient and it works fine if I set the Active property 
to true in the object inspector. If I try to change the Active property 
in code with a (TCP->Active = true;) I get the following error. Is this 
somehow caused by something I may have done.

[Linker Error] Error: Unresolved external '__fastcall 
Sockets::TBaseSocket::SetActive(char)'


Thanks for the Assistance.

There is no SetActive() method in TBaseSocket that takes a char as input. 
TBaseSocket::SetActive() takes a bool instead:

    void __fastcall SetActive(bool Value);
    __property bool Active = {read=FActive, write=SetActive, default=0};

I am aware that it should be a bool but I am passing it a bool and I get 
the Linker Error.

My code compiles and runs and communicates over the TCP connection but 
if I add the following code.

void __fastcall TISDMainForm::Button1Click(TObject *Sender)
{
	bool SetSocketActive;

   	SetSocketActive = true;
	MyTcpClient->Active = SetSocketActive;
}

I get

[Linker Error] Error: Unresolved external '__fastcall 
Sockets::TBaseSocket::SetActive(char)'

I tested this in another program that was empty except for this code and 
it worked fine so there must be something in my project that is causing 
  this. I am not overriding anything in Sockets. I guess I will have to 
reassemble the project piece by piece until I find the part that causes 
this.

Do you have SetSocketActive defined anywhere else, by chance?  Maybe as a 
function that returns a 'char'?  Or maybe there is a macro that is 
redefining 'true' to be a 'char' instead of a 'bool'?  Do you have the same 
error if you change the variable's name, or remove the variable altogether?
