regarding enabling of textbox

well i wish to control the disabling of a edit box by user selecting from a set of option button that is a edit box placed front of that particular option button should be enabled if the user selects that option.......please tell me how can i do so.......the above controls are placed on a dialog box that is been called from the view.cpp.....................
i have disabled the edit boxes initially by properties pane.......

EnableWindow(TRUE);

sorry but how to use this??and where to use this??my control name is IDC_EDIT4 and variable associated is m_z

If m_z is a control variable, then you can say:

Code:

---

m_z.EnableWindow(TRUE); // or FALSE

---

On the other hand you can say:

Code:

---

CWnd* wnd = GetDlgItem(IDC_EDIT4);
wnd->EnableWindow(TRUE); // or FALSE

---
