Lightbox Info Board : SQLの窓

この場合、リストボックスのスタイルを「ソート」にすると、追加されるたびにソートされます


LRESULT CALLBACK About( HWND hDlg, UINT message, WPARAM wParam, LPARAM lParam )
{
	switch( message ) {
		case WM_INITDIALOG:
			return TRUE;

		case WM_COMMAND:

				LOWORD(wParam) == IDCANCEL ) {

				return TRUE;
			}
			if( LOWORD(wParam) == IDC_BUTTON1 ) {
				char szBuffer[128];

				GetDlgItemText( hDlg, IDC_EDIT1, szBuffer, 128 );
				SendMessage(
					GetDlgItem( hDlg, IDC_LIST1),
					LB_ADDSTRING,
					0L,
					(LPARAM)(LPCTSTR)szBuffer
				);
			}
			break;
	}
	return FALSE;
}
