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

Very late reply.

You should have been directed towards Ruby/DL in the  
standard library.

This is now preferred to Win32API which is in the process  
of being obsoleted.
