基于C++的设备自动检测添加_ondevicechange 多设备同时插入

#include <Dbt.h>

重写 OnDeviceChange

BOOL CX3Dlg::OnDeviceChange(UINT nEventType, DWORD dwData)
{
	char* s;
	DEV_BROADCAST_DEVICEINTERFACE* dbd = (DEV_BROADCAST_DEVICEINTERFACE*)dwData;
	switch (nEventType) {
	case DBT_DEVICEREMOVECOMPLETE: 
		if (s = strstr((char*)dbd->dbcc_name, "USB#VID_0483&PID_5740")) {
			X3LOG.Logger_Debug(__FILE__, __LINE__, "USB已移除!\n");
		}else if (s = strstr((char*)dbd->dbcc_name, "BTHENUM#")) {		
			if ((s = strstr((char*)dbd->dbcc_name, "BluetoothDevice_001B10"))
				|| (s = strstr((char*)dbd->dbcc_name, "BluetoothDevice_001B30"))) {
				X3LOG.Logger_Debug(__FILE__, __LINE__, "蓝牙已解绑!\n");
			}
		}
		break;
	case DBT_DEVICEARRIVAL:
		if (s = strstr((char*)dbd->dbcc_name, "USB#VID_0483&PID_5740")) {
				X3LOG.Logger_Debug(__FILE__, __LINE__, "USB已插入!\n");
		}
		else if (s = strstr((char*)dbd->dbcc_name, "BTHENUM#")) {
			if ((s = strstr((char*)dbd->dbcc_name, "BluetoothDevice_001B10")) || (s = strstr((char*)dbd->dbcc_name, "BluetoothDevice_001B30"))) {
				X3LOG.Logger_Debug(__FILE__, __LINE__, "蓝牙已配对!\n");
			}
		}
		break;
	default:
		break;
	}
	return TRUE;
}

 添加事件的监听：

BEGIN_MESSAGE_MAP(CX3Dlg, CDHtmlDialog)
	ON_WM_DEVICECHANGE()
END_MESSAGE_MAP()

 最重要的一步，在加载窗体的时候注册设备通知事件

void CX3Dlg::InitDBT(void * prama) {
	HDEVNOTIFY m_hDeviceNotify;
	CX3Dlg* dlg = (CX3Dlg*)prama;
	static const GUID GUID_DEVINTERFACE_LIST[] =
	{ 0x4d36e978, 0xe325, 0x11ce, { 0xbf, 0xc1, 0x08, 0x00, 0x2b, 0xe1, 0x03, 0x18 } };
	DEV_BROADCAST_DEVICEINTERFACE Filter;
	ZeroMemory(&Filter, sizeof(Filter));
	Filter.dbcc_size = sizeof(Filter);
	Filter.dbcc_devicetype = DBT_DEVTYP_DEVICEINTERFACE;
	for (int i = 0; i < sizeof(GUID_DEVINTERFACE_LIST) / sizeof(GUID); i++) {
		Filter.dbcc_classguid = GUID_DEVINTERFACE_LIST[i];
		m_hDeviceNotify = RegisterDeviceNotification(dlg->m_hWnd, &Filter, DEVICE_NOTIFY_ALL_INTERFACE_CLASSES);
		if (NULL == m_hDeviceNotify) {
			break;
		}
	}
}
