Autoit vs C# Getting Ram issue

[Kovacic 11]

This is a good question for someone familiar with both C# and autoit...

I'm not sure why this is but, when I bring up the installed RAM using C#, I get a different value than when I do with Autoit...

Here are the scripts..

 

Autoit:

$aMem = MemGetStats()
$kb = $aMem[1]
$mb = $kb / 1024
$gb = $mb / 1024
Msgbox(0,"Ram" ,"Size in KB: " & $KB & ", Size in MB: " & $MB & ", Size in GB: " & $GB)

C#:

using System.Reflection;
using System.Runtime.CompilerServices;
using System.Runtime.InteropServices;
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Management;
namespace WindowsApp1
{
    static class Program
    {
        static void Main()
        {
        string Query = "SELECT MaxCapacity FROM Win32_PhysicalMemoryArray";
            ManagementObjectSearcher searcher = new ManagementObjectSearcher(Query);
            foreach (ManagementObject WniPART in searcher.Get())
            {
                UInt32 SizeinKB = Convert.ToUInt32(WniPART.Properties["MaxCapacity"].Value);
                UInt32 SizeinMB = SizeinKB / 1024;
                UInt32 SizeinGB = SizeinMB / 1024;
                MessageBox.Show("Size in KB: " + SizeinKB + ", Size in MB: " + SizeinMB + ", Size in GB: " + SizeinGB);
            }
            
        }

    }
}

Can anyone shed some light as to why they report different RAM sizes? Some computers show a close amount, some show a completely different amount

Thanks!.

What are the numbers you're getting?

[Spider001 5]

Why you don't add

add a reference to "Microsoft.VisualBasic", then create an instance of the type Microsoft.VisualBasic.Devices.ComputerInfo. That corresponds to My.Computer.Info

And use

My.Computer.Info.TotalPhysicalMemory

My.Computer.Info.AvailablePhysicalMemory

Short way c#

Microsoft.VisualBasic.Devices.ComputerInfo.TotalPhysicalMemory

Or this way

Trying this now... Thank you!!

It might be due to integer rounding.

UInt32 SizeinMB = SizeinKB / 1024;

There's a winapi function called something like physicalinstalledmemory or something like that (no access to help file)

[Spider001 5]

'?do=embed' frameborder='0' data-embedContent>>

MsgBox(0, "Title", "GetPhysicallyInstalledSystemMemory = " & _GetPhysicallyInstalledSystemMemory()) 

Func _GetPhysicallyInstalledSystemMemory()     
$aRet = DllCall("Kernel32.dll", "int", "GetPhysicallyInstalledSystemMemory", "uint64*", "")     
If @error Then Return SetError(1, 0, 0)     
Return $aRet[1] 
EndFunc

Yes, there is also func in standard UDF's

_WinAPI_GetPhysicallyInstalledSystemMemory
