1.设置列表属性

#define Dim(arr)	(sizeof(arr) / sizeof(arr[0]))

const CString g_ListColumnText[] = {
	_T("DeviceID"),
	_T("BTName"),
	_T("BTAddress"),
	_T("PhoneBook"),
	_T("Connect"),
};

int g_ListColumnLen[] = {20, 40, 40, 20, 20,};

void CBTDemoDlg::InitDeviceInfoList(void)
{
	DWORD dwStyle = m_DeviceInfoList.GetExtendedStyle();
	dwStyle = dwStyle | LVS_EX_FULLROWSELECT | LVS_EX_GRIDLINES;
	m_DeviceInfoList.SetExtendedStyle(dwStyle);

	for (int index = 0; index < Dim(g_ListColumnLen); ++index)
	{
		m_DeviceInfoList.InsertColumn(index, g_ListColumnText[index], LVCFMT_LEFT, g_ListColumnLen[index] * 3);
	}
}

2.获取选择项中的某个字段

BOOL CBTDemoDlg::GetSelectItemAddress(wstring& strAddress)
{
	for (int index = 0; index < m_DeviceInfoList.GetItemCount(); ++index)
	{
		if (m_DeviceInfoList.GetItemState(index, LVIS_SELECTED) == LVIS_SELECTED)
		{
			CString strBtAddr = m_DeviceInfoList.GetItemText(index, 2);
			strAddress = strBtAddr.GetBuffer(0);
			m_DeviceInfoList.SetItemState(index, 0, LVIS_SELECTED);
			return TRUE;
		}
	}
	return FALSE;
}

3.修改列表的某项中的某些字段

BOOL CBTDemoDlg::ChangeItemStatus(const CString& strAddress, int nStatus, BOOL bConnect)
{
	for (int index = 0; index < m_DeviceInfoList.GetItemCount(); ++index)
	{
		if (m_DeviceInfoList.GetItemText(index, 2) == strAddress)
		{
			TCHAR szStatus[4] = {0};
			_stprintf(szStatus, _T("%d"), nStatus);
			m_DeviceInfoList.SetItemText(index, 3, szStatus);
			m_DeviceInfoList.SetItemText(index, 4, bConnect ? _T("Connect") : _T("Disconnect"));
			return TRUE;
		}
	}

	return FALSE;
}

4.删除列表中的某项

BOOL CBTDemoDlg::DeleteItem(const CString& strAddress)
{
	for (int index = 0; index < m_DeviceInfoList.GetItemCount(); ++index)
	{
		if (m_DeviceInfoList.GetItemText(index, 2) == strAddress)
		{
			m_DeviceInfoList.DeleteItem(index);
			return TRUE;
		}
	}
	return FALSE;
}

5.增加一选项

{
	_stprintf(szStatus, _T("%d"), pInfo->nStatus);
	int nIndex = m_DeviceInfoList.GetItemCount();
	m_DeviceInfoList.InsertItem(nIndex, _T("0"));
	m_DeviceInfoList.SetItemText(nIndex, 1, pInfo->deviceName.c_str());
	m_DeviceInfoList.SetItemText(nIndex, 2, pInfo->deviceAddr);
	m_DeviceInfoList.SetItemText(nIndex, 3, szStatus);
	m_DeviceInfoList.SetItemText(nIndex, 4, FALSE ? _T("Connect") : _T("Disconnect"));
}
