How to get the length of a dialog item text?

Im trying to get the dialog item text into a buffer. It works with GetDlgItemText(), but how do i get the length of the text so i can allocate the buffer before i read it in there? I want to be sure i always get the whole text. I could use always for example 10k buffer, but it would be nicer if there wasnt any chance that the user text isnt received completely.

Send the window handle, obtained by calling GetDlgItem, a WM_GETTEXTLENGTH message. Or if you prefer call GetWindowTextLength.
