You need to redraw the field after you set the handle for it (assuming you're
not doing this elsewhere). Do this with FldDrawField(fldLogin). I'm pretty
rusty with my C/C++ but I think there may also be a problem with the line:
newText = rP->login. This may set the newText pointer to point to the data in
rP->login and not actually copy that data to the allocated space for newText.
You may try StrCopy(newText, rP->login) instead.
Hope this helps.
