Please help me:

How can I make Form1.MainMenu stick to right, without changing the BiDiMode of Form1. I mean any thing is ok but MainMenu1.

More Detail: I'm in XP with Delphi7 and like to run my application in any version of Windows.

var
  MenuItemInfo: TMenuItemInfo;
  Buffer: array[ 0..79 ] of Char;
begin
  MenuItemInfo.cbSize := 44; // Required for Windows 95
  MenuItemInfo.fMask := MIIM_TYPE;
  MenuItemInfo.dwTypeData := Buffer;
  MenuItemInfo.cch := SizeOf( Buffer );
  if GetMenuItemInfo( MainMenu1.Handle, MainMenu1.Items.IndexOf( Edit1 ), True, MenuItemInfo ) then begin
    MenuItemInfo.fType := MenuItemInfo.fType or MFT_RIGHTJUSTIFY;
    SetMenuItemInfo( MainMenu1.Handle, MainMenu1.Items.IndexOf( Edit1 ), True, MenuItemInfo );
  end;
end;

MainMenu1 is my main menu, Edit1 is the second menu-item in the top.

Dear Workshop Alex

Thank You. Your code works fine but there is some questions remaining:
1) How can I force menu items to be redrawn in order to make them appear at right? They are actually right aligned but their position before redrawing does not say so.
2) when I rename Edit1 every thing goes back. why is it so and how much can I trust in this code in special conditions (renaming, changing menuindex, closing form and so on)?

The problem with my solution is that while you explicitly tell the menu to be right-alighned once, the TMemu component isn't really aware of this yet. Thus, when the TMenu recreates the menu for whatever reason, (like renaming) it will bring the menu back to it's original position. Basically, you should inherit a new component from TMainMenu and add the functionality for this new right-alignment property, which is not an easy job. This new component could then respond to changes in the menu and make sure the MFT_RIGHTJUSTIFY is set for a specific menuitem.
Basically, the whole secret behind right-aligned menus is just this flag...
