CB_DELETESTRING
An
application sends a CB_DELETESTRING message to delete a string in the list box
of a combo box.
CB_DELETESTRING
wParam = (WPARAM) index; // item to delete
lParam = 0; // not used; must be zero
Parameters
index
Value of wParam.
Specifies the zero-based index of the string to delete.
Return Values
The return
value is a count of the strings remaining in the list. If the index
parameter specifies an index greater than the number of items in the list, the
return value is CB_ERR.
Remarks
If you create
the combo box with an owner-drawn style but without the CBS_HASSTRINGS style,
Windows sends a WM_DELETEITEM message to the owner of the combo box so the
application can free any additional data associated with the item.
