In winsock.h, where all of the other WinSock functions and structures are
defined.

Did not include winsock.h?

>Did not include winsock.h?

Yea I deserved that.
Since I don't think its possible to look any more stupid...

Why was it not required in the console app?   A couple of messages
back. Did this somehow load it?
       hIcmp = LoadLibrary( "ICMP.DLL" );

Where is the default destructor?  
When I add this is says it has already been defined.
I can't seem to locate it, looked in header.


 __fastcall TForm1::~TForm1()
    {
        if( WasInitialized )
            WSACleanup();
    }

Is it onclose()?

Thanks

You probably included something else that then implicitally included
winsock.h for you.

No.

There is no such thing as a 'default' destructor, because a destructor
cannot be overloaded.  Now, if you are asking why TForm classes do not have
a destructor defined in the header file by default, it is becuse they don't
need one by default.  There is nothing in the default code of the class that
needs explicit destroying in your code, so the compiler-generated destructor
will suffice.  If you need to destroy something yourself, then you have to
add a destructor to your code as needed.

You probably did not define the destructor in your header file:

    public:
        __fastcall TForm1(TComponent *Owner);
        __fastcall ~TForm1(); // <-- add this manually

> Is it onclose()?

No.  That is an event that has nothing to do with the destructor.

Well I don't know where, since these 
#include <windows.h>
#include <stdio.h> 
are the only two includes in the original functioning console program.

Which is why I previously wondered why my console program worked
without winsock.h explicitly included. 

I had previously erroneously thought (prior to your redirection)
windows.h did it.

At first I wondered why I would have to define the destructor in my
header file, if it was complaining that it had already been defined.

But you are right.   I added it to the header and it quit complaining
that it had already been defined.   You can see my confusion with the
error message  "ALREADY DEFINED" !   So I guess by putting one in the
header you effectively override the one the compiler would have used.


So off to further learning

windows.h includes winsock.h

_WIN32_WINNT is set in windows.h to 0x0500 by default, unless defined by the
user's project in the Conditionals list.
