Write simple WMI program

(Diagram: 淺談CIM與WMI-名詞介紹)

WMI (Windows Management Instrumentation) provide a kind of easy way to let you query data from your system (Ex: OS version, share folder name ... etc).

It is easy to understand, using WMI to query information is the same with query data from database. You can just using "SELECT * from Win32_Process" to find out all exist process in your computer.

There are some examples which describe how to create it using C# or C++ code.

1. Example: Creating a WMI Application(C++)
2. WMI Sample  (using C#)

using System.Management;

//This is equivalent to "SELECT * FROM Win32_Service"
SelectQuery sysSQL = new SelectQuery("Win32_bios");

MnagementObjectSearcher sysRet =
   new ManagementObjectSearcher(sysSQL);

// Display each entry for Win32_bios
foreach (ManagementObject sysInfo in sysRet.Get())
{
  this.textBox1.Text = "Bios version: " + sysInfo["version"].ToString();
}
