I want to make my "Help" menu item appear on the right side of the window
I got the source to do this in Delphi - worx fine...but i cant translate the code to C . I'm a Delphi coder and I soon moved to Borland C Builder 4
...I'm SO confused....
Does anyone know any good reference material for such situation?

You can do it via the menu resource, instead of doing it through code. In the MENUITEM of the resource, use \a to right align the menuitem.

MENUITEM text, result, [[optionlist]]  

Parameters
text
A string that indicates the name of the menu item.
The string can contain the escape characters \t and \a. The \t character inserts a tab in the string and is used to align text in columns. Tab characters should be used only in menus, not in menu bars. (For information on menus, see POPUP Resource.) The \a character aligns all text that follows it flush right to the menu bar or pop-up menu.

in fact I need an explanation why doesnt this fine Delphi code work when translated to C:

var
    MMI: TMenuItemInfo;
    MyMenu: hMenu;
    Buffer: array[0..79] of Char;

begin
     MyMenu := GetMenu(Handle);
     MMI.cbSize := SizeOf(MMI);
     MMI.fMask := MIIM_TYPE;
     MMI.dwTypeData := Buffer;
     MMI.cch := SizeOf(Buffer);
     GetMenuItemInfo(MyMenu, 1, True, MMI);
     MMI.fType := MMI.fType or MFT_RIGHTJUSTIFY;
     SetMenuItemInfo(MyMenu, 1, True, MMI);

Any ideas?

void __fastcall TForm1::FormCreate(TObject *Sender)
{
    LPMENUITEMINFO lpmii;
    HMENU M;
    char buffer[110];

  M = GetMenu(Handle);

  lpmii->cbSize = sizeof(lpmii);
  lpmii->fMask = MIIM_TYPE;
  lpmii->dwTypeData = buffer;
  lpmii->cch = sizeof(buffer);

  if (!GetMenuItemInfo(M,1,True, lpmii)) ShowMessage("Failed!" );
// Failes HERE!

//  lpmii->fType = lpmii->fType || MFT_RIGHTJUSTIFY;
//  SetMenuItemInfo(GetMenu(Handle), 1, True, lpmii);
//  ShowMessage(IntToStr(GetMenuString(M,1,title,50,MF_BYPOSITION)));

I'm a BAD C translater!
Also I cant find how to declare string types in C!!! ALL Win functions that are supposed to work with PChars aways fail!...and I tought coding in C for Windows would be easier.... :(

//  lpmii->fType = lpmii->fType || MFT_RIGHTJUSTIFY;

should be

lpmii->fType = lpmii->fType | MFT_RIGHTJUSTIFY;

Notice the || should be |

OK, but it seems my proggie failes before it reaches this line -> notice that it's commented above - My GetMenuItemInfo function FAILES! );

  if (!GetMenuItemInfo(M,1,True, lpmii)) ShowMessage("Failed!" );

That's because you should be using an object and not a pointer to an object:

{
  MENUITEMINFO mii;
  // rest is same
  ZeroMemory(&mii, sizeof(mii)); //Add this line to zero out the buffer before using
  mii.cbSize = sizeof(mii);
  mii.fMask = MIIM_TYPE;
  mii.dwTypeData = buffer;
  mii.cch = sizeof(buffer);

  if (!GetMenuItemInfo(M, 1, True, &mii)) ShowMessage("Failed!" );

THANX!
Finally it workx!
It seems a bit too confusing for me, but I think I should go through some tutorials first, before continuing with C++ ...
....I'd be glad to return the favour, of course if I can...
