IDC_RIGHT, IDC_CENTER not defined ?

[George Ginden]

OK I'm trying to implement text alignment in the edit control.
Now, one question how do I know (in the EDIT_WM_NCCreate for example) if 
the text alignment has been requested by the programmer ?

I guess the GetDlgItem function on es->hwndParent should do the job... 
but IDC_RIGHT and IDC_LEFT are not defined. So How can I get check for 
the requested alignment ?

Regards.
