MFC ListBox DeleteString

For the code below, it will not be able to clear all ListBox string.
int c= m_list.GetCount ();
for(int k=0;k<c;k++)
m_list.DeleteString (i);

The problem is that the index will become 0 ~ n-1 (not 1 ~ n) after you delete index 0.  You need to modify the code below to make the task success.

int c= m_list.GetCount ();
for(int k=0;k<c;k++)
m_list.DeleteString (0);
