MFC使用roid设置全选与反选

//全选
void AllResultsListThcDlg::OnBnRadioAllSelect()
{
	// TODO: 在此添加控件通知处理程序代码
	for (int i = 0; i < list_studentMark.GetItemCount(); i++) {
		list_studentMark.SetCheck(i, TRUE);
		list_studentMark.SetItemState(i, LVIS_SELECTED, LVIS_SELECTED);
	}

}
//反选
//GetCheck()、SetCheck()、GetItemState()、SetItemState()
//获取和设置复选框的状态(打钩否)、获取和设置某一行的状态(选中否)。
void AllResultsListThcDlg::OnBnInvertSelect()
{
	BOOL state;
	for (int i = 0; i < list_studentMark.GetItemCount(); i++) {
		state = list_studentMark.GetCheck(i);
		if (state == FALSE) {
			list_studentMark.SetItemState(i, LVIS_SELECTED, LVIS_SELECTED);
			list_studentMark.SetCheck(i, TRUE);
		}
		else {
			list_studentMark.SetItemState(i, ~LVIS_SELECTED, LVIS_SELECTED);
			list_studentMark.SetCheck(i, FALSE);
		}
	}
}
