System informations?

[janis]

Hi,
now to get system informations like processor type (value Mhz), available memory, processor usage, memory usage ...

System.Management.Instrumentation which are wrappers around WMI classes.

Here is class I did some months back. It uses the WMI classes and assumes that WMI is installed on the client machine.

Thanks for answers, but how to do that with some other computer in network, and how to get memory or processor usage? What I saw, everything get only sistem informations but not currently usage.

You want Performance Counters, and yes they can be read across a network. If you have one of the bigger version of VS .NET (I know for sure Enterprise has it, possibly the one below) then you can create a connection in Server Explorer to a target server, drill into it and see what performance counters it exposes (different OSes may not expose the same counters) and drag/drop it onto your form.

While you don't want to rely on this for a generic utility that will be run against many different servers, it will give you a good idea of how it is done programatically - the code for initializing the counter is up in the "Windows Form Designer generated code" portion of your form's code. An example from my machine:

Friend WithEvents PerformanceCounter1 As System.Diagnostics.PerformanceCounter
    Friend WithEvents PerformanceCounter2 As System.Diagnostics.PerformanceCounter
    <System.Diagnostics.DebuggerStepThrough()> Private Sub InitializeComponent()
        Me.PerformanceCounter1 = New System.Diagnostics.PerformanceCounter()
        Me.PerformanceCounter2 = New System.Diagnostics.PerformanceCounter()
        CType(Me.PerformanceCounter1, System.ComponentModel.ISupportInitialize).BeginInit()
        CType(Me.PerformanceCounter2, System.ComponentModel.ISupportInitialize).BeginInit()
        '
        'PerformanceCounter1
        '
        Me.PerformanceCounter1.CategoryName = ".NET CLR Networking"
        Me.PerformanceCounter1.CounterName = "Bytes Sent"
        '
        'PerformanceCounter2
        '
        Me.PerformanceCounter2.CategoryName = "Processor"
        Me.PerformanceCounter2.CounterName = "% Processor Time"
        Me.PerformanceCounter2.InstanceName = "_Total"
        Me.PerformanceCounter2.MachineName = [b]"mymachinename"[/b]
