Problem is, I can't get the data out from the edit control whenever I type anything in

// Copy contents of edit control to a character array...
TCHAR szBuffer = new TCHAR[editctrl.GetWindowTextLength() + 1];
editctrl.GetWindowText(szBuffer, GetWindowTextLength() + 1);

// Copy contents of edit control to a CString...
CString str;
editctrl.GetWindowText(str);
