Klasse wo aufrufen?

snowleopard

Grünschnabel
Hallo!
Ich hab mich vor kurzem mit Visual c++ angefreundet und
bin nun auf mein erstes problem gestoßen:
ich will eine klasse mit

ClientSocket* sockClient = new ClientSocket;

"global" in einem MDI-child aufrufen. Ohne MDI-child konnte ich
dies einfach an einer stelle im quellcode definieren (siehe ROT).:confused:

funktionieren tuts auch alles wenn ich den oben besagten quellcodeschnipsel
direkt an der stelle ganz unten (siehe GRÜN) einfüge, dann jedoch ist die funktion
nur für den button verfügbar und nicht für andere buttons.


nun die sicherlich lächerliche frage (hey ich bin erst ne woche dabei^^)
wie muss ich den quellcodeschnipsel einfügen damit ich auch mit anderen
buttons auf die funktionen der klasse zugreifen kann? =)

würde mich tierisch über hilfe freuen, fettes mauz!

#include "Socket.h"
#include "WinSock2.h"

using namespace System::ComponentModel;

using namespace System::Windows::Forms;
using namespace System::Data;

using namespace System::Threading; // für timer
using namespace System::Runtime::InteropServices;//Für Marshal
