Changing static text in dialog box at runtime - c++

Question

I have created a dialog box and linked it to the menu item. In this case the menu item is Help -> Statistics. It all works. So when I run the program, click on the menu Help, then Statistics, a dialog box pops up.
I also have a static text box in the dialog box. How do you change the text of this static text box at runtime?
P.S: Though I have a dialog box up and running, I do not have the handle for the dialog box. If any of your solutions involve knowing the handle to the dialog box, please tell me how to retrieve it. Thanks.
EDIT:
class CStatisticsDlg : public CDialogEx
{
public:
CStatisticsDlg();
// Dialog Data
enum { IDD = IDD_STATISTICS };
protected:
virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV support
// Implementation
protected:
DECLARE_MESSAGE_MAP()
public:
};
CStatisticsDlg::CStatisticsDlg() : CDialogEx(CStatisticsDlg::IDD)
{
}
void CStatisticsDlg::DoDataExchange(CDataExchange* pDX)
{
CDialogEx::DoDataExchange(pDX);
}
BEGIN_MESSAGE_MAP(CStatisticsDlg, CDialogEx)
END_MESSAGE_MAP()

In Class Wizard, create a CString member variable for the label. Note: by default, labels don't have a custom id so you have to give it one like IDC_MY_LABEL.
Somewhere before showing the dialog call m_strMyLabel.SetWindowText("blah");
If you need to do it while the dialog is open you have to call UpdateData(FALSE)
Edit: if you don't want to create a member variable you can
**corrected - typing from memory....
// Find the label
// if called from within CStatusDlg class
CWnd *label = GetDlgItem(IDC_MY_LABEL);
label->SetWindowText("blah");
// If called from elsewhere
CStatusDlg dlg..... // create the dialog
CWnd *label = dlg.GetDlgItem(IDC_MY_LABEL);
label->SetWindowText("blah");
