CE驱动动态加载卸载

加载：

#define DEV_KEY TEXT("Drivers\\Builtin\\WCDMA")
BOOL CGPRSCTRLDlg::Load()
{
    //DWORD dwParam = 89;
    //HANDLE hd = ActivateDeviceEx(DEV_KEY,NULL,0,&dwParam);  

    HANDLE hd = ActivateDeviceEx(DEV_KEY,NULL,,NULL);
    if(INVALID_HANDLE_VALUE==hd)
    {
        return FALSE;
    }
    else
    {
        return TRUE;
    }

}

卸载：

BOOL CGPRSCTRLDlg::Unload(const wstring &strDev)
{
    BOOL bRes = FALSE;

    HANDLE hFind = INVALID_HANDLE_VALUE;
    __try
    {
        if(strDev.empty() != FALSE)
        {
            RETAILMSG(DEBUGMESSAGE, (TEXT("[CGPRSCTRLDlg] Unload leave1\r\n")));
            __leave;
        }

        //确定搜索的方式
        DeviceSearchType searchType;
        ] == ':')
        {
            searchType = DeviceSearchByLegacyName;
        }
        else
        {
            searchType = DeviceSearchByDeviceName;
        }

        DEVMGR_DEVICE_INFORMATION devInfo = {};
        devInfo.dwSize = sizeof(devInfo);

        //寻找驱动的句柄
        hFind = FindFirstDevice(searchType,strDev.c_str(),&devInfo);
        if(hFind == INVALID_HANDLE_VALUE)
        {
            RETAILMSG(DEBUGMESSAGE, (TEXT("[CGPRSCTRLDlg]  Unload leave2\r\n")));
            __leave;
        }

        //卸载驱动
        bRes = DeactivateDevice(devInfo.hDevice);
        RETAILMSG(DEBUGMESSAGE, (TEXT("[CGPRSCTRLDlg] DeactivateDevice\r\n")));
    }
    __finally
    {
        FindClose(hFind);
    }
    return bRes;

}

调用：

//加载
Load();

//卸载
Unload(_T("COM6:"));
