      this->tabPage1 = gcnew TabPage;
      this->tabPage2 = gcnew TabPage;
      array<Control^>^temp0 = {this->tabPage1,this->tabPage2};
      this->tabControl1->Controls->AddRange( temp0 );
      this->tabControl1->Padding = Point(15,10);
      this->tabControl1->Location = Point(35,25);
      this->tabControl1->Size = System::Drawing::Size( 220, 220 );
