Finds the first string in a list box that contains the specified prefix without changing the list-box selection.

int FindString(
   int nStartAfter,
   LPCTSTR lpszItem 
) const;



Contains the zero-based index of the item before the first item to be searched. When the search reaches the bottom of the list box, it continues from the top of the list box back to the item specified by nStartAfter. If nStartAfter is –1, the entire list box is searched from the beginning.


Points to the null-terminated string that contains the prefix to search for. The search is case independent, so this string may contain any combination of uppercase and lowercase letters.

The zero-based index of the matching item, or LB_ERR if the search was unsuccessful.

Use the SelectString member function to both find and select a string.

// The pointer to my list box.
extern CListBox* pmyListBox;
// The string to match.
extern LPCTSTR lpszmyString;

// Delete all items that begin with the specified string.
int nIndex = 0;
while ((nIndex=pmyListBox->FindString(nIndex, lpszmyString)) != LB_ERR)
   pmyListBox->DeleteString( nIndex );
