#include "objbase.h"
void __fastcall TForm1::Button1Click(TObject *Sender)
{
TGUID guid;
WideChar WCLID[128];
int Start;
CoCreateGuid(&guid);
StringFromGUID2(guid,WCLID,sizeof(WCLID)/2);
Edit1->Text = WideCharToString(WCLID);
Start = Edit1->Text.Length()-12;
Edit2->Text = Edit1->Text.SubString(Start,12);
}
