How to lock an edit box?
-
Hi, all I was wondering how to lock (not disable) an edit box during runtime, so the content (the text) in the control can still be selected but not modified/edited. I am using regular Windows API (no MFC) and I also want to be able to unlock the edit box. Thanks in advance :) Aidman » over and out We haven't inherited Earth from our parents, instead we have borrowed her from our children; an old Indian saying.

Either use the
ES_READONLYstyle when you create it, or theEM_SETREADONLYmessage (CEdit::SetReadOnlyif you use MFC) at any time after creatign the control

if you want to do this easily, you'll probably want to use CRichEditCtrl with the read only property enabled instead of CEdit

You can do that to an Edit, too...

doesn't setting read only on an Edit gray the box by default? If so, and I can remember it doing that, you'd have to subclass and override. That's why I suggested the rich edit instead.
yes it does - (I thought that would be ok with the asker) However, there's a message you can override in the dialog to proivde a different background brush. Peter

As others have mentioned, you use the EM_SETREADONLY message. However, this will cause the edit box to be grayed out. You can still select the text, copy it, etc.. If you want the control to look like a normal edit control, but be read-only, then you need to catch WM_CONTROLCOLOR and look for the controls window handle and return a brush that's the same as the users color preferences. I'd advise against that, though. It confuses users when a control looks editable, but really isn't. -- Where are we going? And why am I in this handbasket?
