How to lock an edit box?

Hi, all

I want to create an edit box and have it locked (not disable), so the content (the text) in the control can still be selected but not modified/edited. I am using regular Windows API, no MFC.

Thanks in advance :)

Create the edit box with the ES_READONLY style.

But I want to be able to lock and unlock the edit box during runtime. Isn't there any window message that could be sent?

Edit:
Sorry I should have mentioned that earlier :(

Wuppy :D

I found it, the EM_SETREADONLY message.
Thanks adrianxw, it was your tip on ES_READONLY that helped me find it :)
