I don’t think it’s possible, at least with any certainty. The whole point of a virtual printer is to imitate a real one as closely as possible, so any differences you can identify are basically just bugs in the virtual printer. That said, you can make some guesses based on the PortName. Just for a … Read more
System.Environment.ProcessorCount returns the number of logical processors http://msdn.microsoft.com/en-us/library/system.environment.processorcount.aspx For physical processor count you’d probably need to use WMI – the following metadata is supported in XP/Win2k3 upwards (Functionality enabled in SP’s prior to Vista/Win2k8). Win32_ComputerSystem.NumberOfProcessors returns physical count Win32_ComputerSystem.NumberOfLogicalProcessors returns logical (duh!) Be cautious that HyperThreaded CPUs appear identical to multicore’d CPU’s yet the performance … Read more
For the record, the PowerShell code is: Get-WmiObject -Class Win32_DesktopMonitor | Select-Object ScreenWidth,ScreenHeight I get the same values in Landscape or in Portrait mode. UPDATE: In a multi monitor environment you can get the info for all monitors with: PS> Add-Type -AssemblyName System.Windows.Forms PS> [System.Windows.Forms.Screen]::AllScreens BitsPerPixel : 32 Bounds : {X=0,Y=0,Width=1280,Height=800} DeviceName : \\.\DISPLAY1 Primary … Read more
You can use pywinrm library instead which is cross-platform compatible. Here is a simple code example: #!/usr/bin/env python import winrm # Create winrm connection. sess = winrm.Session(‘https://10.0.0.1’, auth=(‘username’, ‘password’), transport=”kerberos”) result = sess.run_cmd(‘ipconfig’, [‘/all’]) Install library via: pip install pywinrm requests_kerberos. Here is another example from this page to run Powershell script on a remote … Read more
The Win32_DeviceChangeEvent reports just the type of event that occurred and the Time of the event (uint64, representing 100-nanosecond intervals after January 1, 1601, UTC). No that much useful if you also want to know what arrived or was removed. I suggest to use instead the WqlEventQuery class, setting its EventClassName to __InstanceOperationEvent. This system … Read more
I don’t know of any books specific to Java, but If I can offer some advice it would be to just start with WMI MSDN documentation. Also, since WMI is a COM based API, I would look into using a Java to COM bridge for accessing the API. Any one of the following should work: … Read more
I learned that WMI cannot create files on a remote host, and it cannot copy files over a network connection: http://msdn.microsoft.com/en-us/library/windows/desktop/aa389288%28v=vs.85%29.aspx However, it can run a cmd process. Here’s Frank White’s code in C sharp, followed by his example: https://stackoverflow.com/a/8913231/1569434 InputParameters(“CommandLine”) = “cmd /c echo myFTPCommands > c:\ftpscript.txt” You will need four things to use … Read more
No, it can’t be guaranteed that it will be unique, as the processor might not even support the CPUID instruction, in which case, the call can’t be guaranteed to succeed. Also, you are neglecting that a machine might have multiple processors in it, so getting the id of a single processor doesn’t help. As others … Read more
For others who may come by here, maybe take a look at : http://openhardwaremonitor.org/ Follow that link and at first you might think, “Hey, that’s an application, and that is why it was removed. The question was how to do this from C# code, not to find an application that can tell me the temperature…” … Read more
This Class performs a series of queries on the WMI Win32_DiskDrive class and its associators: Win32_DiskDriveToDiskPartition and CIM_LogicalDiskBasedOnPartition, to retrieve informations on the active USB Drives on a System (local or remote). It might seem redundant (probably because it is), since you just asked for the USB Drives Serial Number. But, you never know what … Read more
