Controls

[ChrisO]

I'm using a dialog based MFC app to create a simple calculator app.
How do I display the input from the user and the results of the calculation on the screen.
I've tried using an edit control but this isnt correct as I dont want the user to edit the results I just want to display it.

Also what function do I use to display

Why not use an edit control in read-only mode? Use the control properties in the dialog editor to set this style. If you want to output alpha-numeric characters to a window, you can use TextOut or DrawText. Don't let the function names confuse you - t

You can also use a static control. If you process the WM_CTLCOLORSTATIC message. it can look just like an edit control but is
uneditable by the user. Display your numbers by using m_static.SetWindowText();

Just another alternative. I like this method because an edit control becomes gray if readonly.

Good luck.

I would suggest a CEdit derived class which doesn't allow any input from the user -- that way the user could still copy the contents of the edit control to the clipboard.

GetDlgItem(ID_EDIT)->EnableWindow(FALSE);//disable the edit ctrl
GetDlgItem(ID_EDIT)->EnableWindow(TRUE);//Enable the edit ctrl
alternatively use static text contol instead
