Assuming that s is a class member you should check if the dialog exists already and create it only if not. Otherwise you have multiple dead dialogs.

You are setting nX to the left of the rectangle of a list control item which is usually zero. Use the debugger to check the values you are passing.

Solution 1

Where first parameter=left margin
second = top
third = width
fourth = height

CRect rect =CRect(150, 40, 831, 576);

m_CDialog1->MoveWindow(rect);
m_CDialog1->ShowWindow(SW_SHOW);
