Change Edit Box content when Button is clicked in mfc

Question

I have an Edit Box and a Button on a dialog. How can I change the content in the edit box runtime as the button is clicked? I have to read a new record from a file and post it in the Edit Box as the Button is clicked and I am using mfc.

Answer 1

Once you have trapped the button press, in most cases the easiest way to change text in an Edit Control is:

SetDlgItemText(IDC_EDIT_ID, "Desired Text String")

Where IDC_EDIT_ID is the ID of the Edit Control (set in the properties window)
