LBN_SELCHANGE Overview  Group

An application sends the LBN_SELCHANGE notification message when the selection in a list box is about to change. The parent window of the list box receives this notification message through the WM_COMMAND message.

LBN_SELCHANGE 

idListBox = (int) LOWORD(wParam);  // identifier of list box 

hwndListBox = (HWND) lParam;       // handle of list box 

 

Remarks

This notification message is not sent if the LB_SETCURSEL message changes the selection.

This notification message applies only to a list box that has the LBS_NOTIFY style.

For a multiple-selection list box, the LBN_SELCHANGE notification is sent whenever the user presses an arrow key, even if the selection does not change.
