    Please explain what you mean. Do you mean the SIZE of the file?

    Just the overall memory usage of the computer.

    Really doesn't matter anymore, with SWAP FILES and all. Perhaps if you told exactly what the problem that you're having, or trying to solve?

    Re: Visual Basic 2010 displaying RAM usage.

    I run servers with 32GB's of RAM, I want to run a visual basic "coded" program to monitor the RAM usage and put it in a listbox, i have already done it with CPU usage, I just want to know how to do it with RAM.

    Re: Visual Basic 2010 displaying RAM usage.

    see if you like this (attached vs 2010 project):
    Code:
    Public Class frmWinCounter
        Protected cpuCounter As System.Diagnostics.PerformanceCounter
        Protected ramCounter As System.Diagnostics.PerformanceCounter
        Protected tmr As System.Timers.Timer
        Sub New()
    
            ' This call is required by the designer.
            InitializeComponent()
    
            tmr = New System.Timers.Timer(500)
            AddHandler tmr.Elapsed, AddressOf Me.tmr_Elapsed
    
            ' Add any initialization after the InitializeComponent() call.
            cpuCounter = New System.Diagnostics.PerformanceCounter()
            cpuCounter.CategoryName = "Processor"
            cpuCounter.CounterName = "% Processor Time"
            cpuCounter.InstanceName = "_Total"
            ramCounter = New System.Diagnostics.PerformanceCounter("Memory", "Available MBytes")
            'init cpu counter 
            Dim tmp As Single = cpuCounter.NextValue()
    
        End Sub
        Private Sub btnCheckRamCpu_Click(sender As System.Object, e As System.EventArgs) Handles btnCheckRamCpu.Click
            tmr.Enabled = Not tmr.Enabled
            If tmr.Enabled Then
                btnCheckRamCpu.Text = "Stop monitor ram cpu"
            Else
                btnCheckRamCpu.Text = "Start monitor ram cpu"
            End If
        End Sub
    
        Private Delegate Sub dlgUpdateUI(ByVal ctl As Control, ByVal text As String)
    
        Private Sub tmr_Elapsed(sender As Object, e As Timers.ElapsedEventArgs)
            Dim cpumsg As String = "Cpu usage: " & cpuCounter.NextValue().ToString("#0") + "%"
            Dim rammsg As String = "Ram usage: " & ramCounter.NextValue().ToString("###,###,##0") + " Mb"
            If Me.InvokeRequired Then
                Dim d As New dlgUpdateUI(AddressOf SetLblText)
                Me.Invoke(d, lblCpu, cpumsg)
                Me.Invoke(d, lblRam, rammsg)
            Else
    
                SetLblText(lblCpu, cpumsg)
    
                SetLblText(lblRam, rammsg)
            End If
        End Sub
    
        Private Sub frmWinCounter_FormClosing(sender As System.Object, e As System.Windows.Forms.FormClosingEventArgs) Handles MyBase.FormClosing
            tmr.Enabled = False
        End Sub
    
        Private Sub SetLblText(lbl As Label, sText As String)
            lbl.Text = sText
        End Sub
    
    End Class

    Re: Visual Basic 2010 displaying RAM usage.

    PS: Much easier in Powershell

    Code:
    while ($true)
    {
    Start-Sleep -s 15
    cls
    ‘CPU Load is’ Get-WmiObject win32_processor | select LoadPercentage  |fl
    }
    Updates every 15 seconds

    Powershell
    and you could also get info about ram:
    http://mintywhite.com/windows-7/7mai...ick-windows-7/
    but this is vb.net forum...
    so you should call wmi through net, like here:
