tab strip.
using namespace System::Drawing;
using namespace System::Windows::Forms;
public ref class Form1: public Form

TabPage^ tabPage4 = gcnew TabPage;
TabPage^ tabPage5 = gcnew TabPage;
Label^ label1 = gcnew Label;
// Allows multiple rows of tabs in the tabControl1 tab strip.
tabControl1->Multiline = true;
tabControl1->SizeMode = TabSizeMode::FillToRight;
tabControl1->Padding = Point(15,5);
array<Control^>^temp0 = {tabPage1,tabPage2,tabPage3,tabPage4,tabPage5};
tabControl1->Controls->AddRange( temp0 );
tabControl1->Location = Point(35,65);
tabControl1->Size = System::Drawing::Size( 220, 180 );
// Gets the number of rows currently in the tabControl1 tab strip.
// Assigns int value to the rows variable.
int rows = tabControl1->RowCount;
label1->Text = System::String::Concat( "There are ", rows, " rows of tabs in the tabControl1 tab strip." );
