Get the total amount of pages from Win32_PrintJob

由 早过忘川 提交于 2020-01-21 03:48:05
问题 The Win32_PrintJob WMI class has lots of properties. (see: Win32_PrintJob on MSDN) I have a small .NET application that poles the printing jobs and displays the jobs' information. The TotalPages propery gives the amount of pages sent. But that figure DOESN'T take into account the number of copies requested by the user. So, if a user wants to print 5 copies of a two page document, the value of TotalPages will be 2, not 10. How can i get the number of copies for a printing job, or get the total

WMI returns information in different formats

由 爷，独闯天下 提交于 2020-01-17 11:17:52
问题 I want to read the hardware configuration to check if a license for my software is valid. Currently, I tried using WMI . This works fine on many machines for several weeks but sometimes, without an obvious reason, WMI returns the hardware configuration in a different format. For example, the serial number of the primary hard disc is converted from characters to a hex string, with all character hex values being swapped pair wise. I figured out that different Windows user types (admin/normal)

Set administrative privileges in C#

由 十年热恋 提交于 2020-01-17 01:44:10
问题 I have been writing many scripts using WMI and a lot of them only work if I start visual studio with "Run as Administrator". Is there a way to set that programmatically with .Net or other means? Eventually, these scripts will be run as .exes from Unity3D so I need to automate setting these rights before running them. Ideally I'm hoping this can all be done in C#. 回答1: This question was answered in the comments. The only way is to add a manifest file to your project that sets the required

WMI常见问题及解决方法

由 只谈情不闲聊 提交于 2020-01-16 02:31:32
一． 常见问题及解决方法 1. 当通过WMI添加服务器、Microsoft .NET、Exchange服务器时，提示“验证失败。请确认用户名和密码”。 解决方法: 请以<domainname>\<username>格式输入用户名 注意： OpManger中对于本地WMI验证，不需要输入用户名和密码。 2. 当以WMI模式监控Windows服务器时，内存利用率数据显示错误。 解决方法: 在WMI中，我们使用Win32_OperatingSystem获取Windows2003服务器的内存数据。在系统内存超过4GB时，则不能报告准确的信息。这是Windows 2003 SP1的一个问题。请参阅 http://support.microsoft.com/kb/906868/ 了解更多信息，并安装补丁。 3. 如何重建WMI类? 解决方法: MOF (受管理对象格式)文件是一个机制，通过它关于WMI类的信息进入WMI存储库。存储库中的类定义可能损坏，这种情况下， 重新编译MOF文件，用最初安装操作系统时的类定义将其复写和替换。 在命令提示符执行以下命令： Windows 2003/XP * c:\windows\system32\wbem\Mofcomp.exe c:\windows\system32\wbem\cimwin32.mof * c:\windows\system32\wbem

WMI: Get list of all serial (COM) ports including virtual ports

由 喜夏-厌秋 提交于 2020-01-14 05:20:07
问题 I'm currently working on a little C# program to interact with an Arduino microcontroller. The program has a combobox where you can choose the COM-port. The µc is connected by USB and a virtual COM-port (CH340). I use the code below to fill in the avaible COM-ports to the combobox. private void Form1_Load(object sender, EventArgs e) { string[] PortNames = SerialPort. GetPortNames(); comboBoxPort.Items.AddRange(PortNames); } The downside of this is, you have to take a look into the Device
