Hello im trying to develop a small app that i can use as a console to output data (strings). Right now i have a dialog based app and i use a Edit box to display a line (via CDialog::SetDlgItemText(IDC_EDIT1,msg) but when trying to add another line it just cancels the first line and rights the second. Is there a way to get it to start a new line and then write?(think quake3 startup app) Sorry if its a bit confusing.
