I use SetWindowText to put a string into an single line edit control. This string contains a '\t' tab character. One my computer this character is correctly resolved into space characters, but on a friend's computer it appears as one strange char (like a compressed rectangle). We both have WinXP SP2. If I copy this strange character into a text editor it is correctly displayed as several spaces. Does anyone know, how to fix this or what the reason might be?
Any help would be appreciated.
