Subject: ruby win32api call getMenuItemInfo

Hi all,

I have successfully managed to implement the following apis

findWindow=Win32API.new("user32.dll", "FindWindow", ['P','P'], 'N')
sendMessage=Win32API.new("user32.dll", "SendMessage",['N','N','N','P'],
'N')
getMenu=Win32API.new("user32.dll", "GetMenu", ['N'], 'N')
getMenuItemCount=Win32API.new("user32.dll", "GetMenuItemCount",['N'],
'N')
getSubMenu=Win32API.new("user32.dll", "GetSubMenu", ['N','N'], 'N')
deleteMenu=Win32API.new("user32.dll", "DeleteMenu", ['N','N','N',],'N')
drawMenuBar=Win32API.new("user32.dll", "DrawMenuBar", ['N'], 'N')
setWindowLong=Win32API.new("user32.dll", "SetWindowLong",['N','N','N'],
'N')

but am unable to get getMenuItemInfo to work, this is because it takes a
type structure and boolean as parameters and i can't figure it out...

this is what i have

getMenuItemInfo =Win32API.new("user32.dll", "GetMenuItemInfo",
['L','L','NEED','NEED'], 'L')

the api is as follows...

BOOL GetMenuItemInfo(
    HMENU hMenu,
    UINT uItem,
    BOOL fByPosition,
    LPMENUITEMINFO lpmii
);

typedef struct tagMENUITEMINFO {
  UINT    cbSize;
  UINT    fMask;
  UINT    fType;
  UINT    fState;
  UINT    wID;
  HMENU   hSubMenu;
  HBITMAP hbmpChecked;
  HBITMAP hbmpUnchecked;
  ULONG_PTR dwItemData;
  LPTSTR  dwTypeData;
  UINT    cch;
  HBITMAP hbmpItem;
} MENUITEMINFO, *LPMENUITEMINFO;

any help greatly appreciated...

Thanks

Ted
