Thanks. I can now properly display a Unicode menu and detect when menu 
items are clicked. However, I'm still wondering about one thing...

#define IDM_MENU_ITEM1 0x00001234
AppendMenuW(MyPopUpMenu,MF_STRING,IDM_MENU_ITEM1,MyWideString);

So, intercepting WM_COMMAND in WndProc when the menu item is clicked 
results in WParamLo containing 0x1234. Based on this value I can 
determine which menu item was actually clicked.

This works great. But I'm wondering if my arbitrary 0x1234 WParamLo 
value that isn't going to potentially run into conflicts with other UI 
actions (e.g. menu items generated by VCL).

Are there any rules as to which values I can use safely use for WParamLo  ?

Thanks,

Kris
