windows10命令提示符的MSG命令的获取会话名称时的错误5、错误1722分别是什么意思？
windows10命令提示符的MSG命令的获取会话名称时的错误5、错误1722是设置错误造成的，解决方法为：
1、对于磁盘中的剩余的可用空间，可使用diskpart命令将其创建为分区。
2、在命令提示符窗口输入命令“create partition logical”。
3、按【Enter】键即可成功的将磁盘中的剩余的可用空间创建为分区。
4、使用“list volum”命令查看磁盘中的卷，即可看到新创建的卷4没有驱动器号。
5、在命令提示符窗口输入命令“select volume 4”，按【Enter】键选择卷并给予其焦点。
6、在命令提示符窗口输入命令“assign letter=F”，按【Enter】键即可成功将驱动号F分配给卷4。
windows无法停用Generic-MS/MS-Pro USB Device设备，原因是某个程序正在使用它。但我什么也没插？
如题。也就是说真的有程序在使用USB设备的文件。所以，办法就是找到访问的程序，然后关闭它，或关闭它所打开的文件。如果是您打开了USB设备的文件，则很容易知道和处理，以下常见的打开的文件但又不易发现的情况，请参考： -windowsgenericmsg
1.音乐视频播放器打开了
2.杀毒软件对访问的文件进行查杀
3.杀毒软件定时扫描
4.其他网络上的入侵或本机木马程序在访问
5.USB设备上本身有活动病毒文件正在被自动运行
6.在文件浏览器浏览USB设备文件
由于 Windows 无法加载这个设备所需的驱动程序，导致这个设备工作异常。 (代码 31)这个怎么解决？
这是因为接口没有安装驱动。
1、首先需要在”控制面板“列表里，找到并点击名称为”设备管理器“按钮选项：
2、接着需要在接下来页面框中点击”网络适配器“，在其列表右击选择”更新驱动程序“按钮：
3、最后只需要在接下来弹出的页面框中点击”自动搜索更新的驱动程序软件“按钮选项即可解决问题：
Qt怎样处理Windows消息
Qt处理Windows消息的方法
一、用到的头文件和函数
首先，要想在Qt工程中处理Windows消息，你必须包含对应的Windows头文件windows.h。如果还需要用到一些扩展的组件，则还要包含windowsx.h。
此外，你需要实现继承自QWidget类的虚函数nativeEvent。这个函数名也很好记，即本地事件。注意，这是一个保护类型成员。
该函数的声明为
virtual bool
nativeEvent(const QByteArray eventType, void *message, long *result);
注意，在Windows平台上，事件类型标识为 "windows_generic_MSG"，消息类型为MSG*，返回值类型为LRESULT。
二、示例
首先，我们在类中声明nativeEvent函数。
接着，我们对参数类型进行转换。
然后，就可以像往常一样通过switch来处理Windows消息了。
在此需要提醒大家注意的是，如果我们处理完相应的消息后，不再想让Qt执行默认的事件处理，就返回true，表示消息已处理；否则，就返回false，执行完指定的操作后再执行默认处理。
Qt的窗口消息处理函数是哪个
重写窗体的nativeEvent事件，就可以了。
示例代码:
函数声明:
protected:
bool nativeEvent(const QByteArray eventType, void *message, long *result);
函数定义:
bool GWSMainWindow::nativeEvent(const QByteArray eventType, void *message, long *result)
{
if (eventType == "windows_generic_MSG")
{
MSG* msg = reinterpret_castMSG*(message);
switch (msg-message)
{
case WM_COPYDATA:
{
COPYDATASTRUCT *copyData = (COPYDATASTRUCT*)msg-lParam;
int nDataSize = copyData-cbData;
if(nDataSize 0)
{
char* ch = new char[nDataSize];
memcpy(ch, copyData-lpData, nDataSize);
QString strMsg = QString::fromUtf8(ch);
delete [] ch;
m_msgList.append(strMsg);
int nIndex = m_msgList.count() - 1;
PostMessage((HWND)this-winId(), MYWM_HANDLECOPYDATA, copyData-dwData, nIndex);
}
return true;
}
case MYWM_HANDLECOPYDATA://自定义消息
{
return handleCopyDataMsg(msg-lParam, msg-wParam);
}
case MYWM_UPDATESOFTMGRICON:
{
int nCount = (int)msg-lParam;
m_pSysTitleWidget-updateSoftMgrIcon(nCount);
return true;
}
default:
return QWidget::nativeEvent(eventType, message, result);
}
}
else
return QWidget::nativeEvent(eventType, message, result);
}
高手进阶：给WINDOWS服务加上描述
; 当我们创建一个WINDOWS服务后 却发觉我们所创建的服务没有相关的描述 （你可以打开服务管理器程序查看） 而System ServiceProcess ServiceBase这些相关的类都没有提供这方面的信息 同样如果我们需要给我们的服务加上恰当的描述 我们也只能通过非托管代码来处理 -windowsgenericmsg

在安装完成后 我们对服务进行 这里可以修改的内容包括服务的描述 服务的故障处理等
如果你在安装时 需要对服务进行自动处于运行状态 或卸载时需要自动将服务也卸载 你只要注册
this beforeuninstall+=new InstallEventHandler(ProjectInstaller_BeforeUninstall); this Committed+=new InstallEventHandler(ProjectInstaller_Committed);-windowsgenericmsg
这二个事件
mitted事件 在这里可以将安装的服务进行调整到运行状态
