How to Implement the right-aligned effect of the Help menu in Total Commander on the menu bar

In Total Commander, how does one align the Help menu on the right of the menu bar? How does one use C?

Thank you for your guidance and finally found a solution.

[StructLayout (LayoutKind. Sequential)]
Public class MenuItemInfo
{
Public Int32 cbSize;
Public Int32 fMask;
Public Int32 fType;
Public Int32 fState;
Public Int32 wID;
Public IntPtr hSubMenu;
Public IntPtr hbmpChecked;
Public IntPtr hbmpUnchecked;
Public IntPtr dwItemData;
Public string dwTypeData;
Public Int32 cch;
}

[DllImport ("user32.dll", CharSet = CharSet. Auto)]
Public static extern bool GetMenuItemInfo (
HandleRef menuHandle,
Int32 itemIndex,
Bool byPosition,
[In, Out] MenuItemInfo menuItemInfo );

[DllImport ("user32.dll", CharSet = CharSet. Auto)]
Public static extern bool SetMenuItemInfo (
HandleRef menuHandle,
Int32 itemIndex,
Bool byPosition,
MenuItemInfo menuItemInfo );

Const Int32 MIIM_FTYPE = 0x00000100;
Const Int32 MFT_RIGHTJUSTIFY = 0x00004000;

Public static void RightJustifyMenuItem (MenuItem menuItem)
{
HandleRef menuHandle = new HandleRef (menuItem. Parent, menuItem. Parent. Handle );
MenuItemInfo menuItemInfo = new MenuItemInfo ();
MenuItemInfo. cbSize = Marshal. SizeOf (typeof (MenuItemInfo ));
MenuItemInfo. fMask = MIIM_FTYPE;
GetMenuItemInfo (menuHandle, menuItem. Index, true, menuItemInfo );
