This is already done for you and depends on the life time of the dialog object. Also update the list control in a callable method other than OnInitDialog. So each time you call DoModal, it will be on the same object of the dialog class.

Keep the values in some sort of container (e.g., list, array).

What others said is right. You have to store the data - the data that's supposed to be shown - elsewhere and in order to show that data in the control, you have to feed that, may be through the dialog object, may be something like this.

CMyDialog : public CDialog
{
public:
CMyDialog(CListCtrlData *pd):m_pd(pd)...
BOOL OnInitDialog(...)
{
//...
// fill the list ctrl with the data
//...
}
private:
CListCtrlData *m_pd;
};

CListCtrlData gDataA;

void SomeFunction()
{
CMyDialog dlg(&gDataA);
dlg.DoModal();
}

CListCtrlData gDataB;

void SomeOtherFunction()
{
CMyDialog dlg(&gDataB);
dlg.DoModal();
}

If the data is supposed to be editable, just make sure that your data class has appropriate methods to update and call these methods from the relevant event handlers for the control.

this question leads to the great theme of separating data from the GUI => MVC http://en.wikipedia.org/wiki/Model_View_Controller[^] Do your homeworks... :-O Press F1 for help or google it. Greetings from Germany
