Hera s the function UpdateWindowsList WindowMenu   that you must call after any operations are performed on Tabs Here windowToolStripMenuItem is the menu item added to Window Menu to menu strip   public void UpdateWindowsList WindowMenu               get all tab pages from tabControl1       TabControl TabPageCollection tabcoll   tabControl1 TabPages           get  windowToolStripMenuItem drop down menu items count       int n   windowToolStripMenuItem DropDownItems Count           remove all menu items from of windowToolStripMenuItem       for  int i   n - 1  i  gt  2  i--                    windowToolStripMenuItem DropDownItems RemoveAt i                    read each tabpage from tabcoll and add each tabpage text to windowToolStripMenuItem       foreach  TabPage tabpage in tabcoll                      create Toolstripmenuitem           ToolStripMenuItem menuitem   new ToolStripMenuItem              String s   tabpage Text            menuitem Text   s             if  tabControl1 SelectedTab    tabpage                            menuitem Checked   true                        else                           menuitem Checked   false                           add menuitem to windowToolStripMenuItem           windowToolStripMenuItem DropDownItems Add menuitem                add click events to each added menuitem           menuitem Click    new System EventHandler WindowListEvent Click                  private void WindowListEvent Click object sender  EventArgs e              casting ToolStripMenuItem to ToolStripItem       ToolStripItem toolstripitem    ToolStripItem sender           create collection of tabs of tabContro1         check every tab text is equal to clicked menuitem then select the tab       TabControl TabPageCollection tabcoll   tabControl1 TabPages        foreach  TabPage tb in tabcoll                    if  toolstripitem Text    tb Text                            tabControl1 SelectedTab   tb                  call UpdateWindowsList WindowMenu   to perform changes on menuitems               UpdateWindowsList WindowMenu

Here   s some code you can use to get a list of all the open windows  Actually  you get a dictionary where each item is a KeyValuePair where the key is the handle  hWnd  of the window and the value is its title  It also finds pop-up windows  such as those created by MessageBox Show  using System Runtime InteropServices  using HWND   System IntPtr        lt summary gt Contains functionality to get all the open windows  lt  summary gt  public static class OpenWindowGetter          lt summary gt Returns a dictionary that contains the handle and title of all the open windows  lt  summary gt         lt returns gt A dictionary that contains the handle and title of all the open windows  lt  returns gt    public static IDictionary lt HWND  string gt  GetOpenWindows           HWND shellWindow   GetShellWindow        Dictionary lt HWND  string gt  windows   new Dictionary lt HWND  string gt          EnumWindows delegate HWND hWnd  int lParam              if  hWnd    shellWindow  return true        if   IsWindowVisible hWnd   return true         int length   GetWindowTextLength hWnd         if  length    0  return true         StringBuilder builder   new StringBuilder length         GetWindowText hWnd  builder  length   1          windows hWnd    builder ToString          return true          0        return windows         private delegate bool EnumWindowsProc HWND hWnd  int lParam       DllImport  quot USER32 DLL quot      private static extern bool EnumWindows EnumWindowsProc enumFunc  int lParam       DllImport  quot USER32 DLL quot      private static extern int GetWindowText HWND hWnd  StringBuilder lpString  int nMaxCount       DllImport  quot USER32 DLL quot      private static extern int GetWindowTextLength HWND hWnd       DllImport  quot USER32 DLL quot      private static extern bool IsWindowVisible HWND hWnd       DllImport  quot USER32 DLL quot      private static extern IntPtr GetShellWindow       And here   s some code that uses it  foreach KeyValuePair lt IntPtr  string gt  window in OpenWindowGetter GetOpenWindows        IntPtr handle   window Key    string title   window Value     Console WriteLine  quot  0    1  quot   handle  title      Credit  http   www tcx be blog 2006 list-open-windows
