Hello!

I'm using this code to detect the cpu temperature.
But I get the error: "The type or namespace name 'ManagementClass' could not be found (are you missing a using directive or an assembly reference?)", But I think I use all usings I need.

I'm using visual C# 2010

This is my code:

using System;
using System.Windows.Forms;
using System.Management;

namespace Heater
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {

            ManagementClass processClass = new ManagementClass(@"root\WMI:MSAcpi_ThermalZoneTemperature");

            foreach (ManagementObject service in processClass.GetInstances())
            {
                MessageBox.Show("CPU Temperature: " + service.GetPropertyValue("CurrentTemperature"));
            }
        }


        static decimal ConvertToCelsius(string reading)
        {

            return (decimal.Parse(reading) / 10 - 273.15m);

        }
    }
}

I want the output to label1, but that's not important now, because the script isn't working.

If I remove all unused usings, system.management is gone too!

Thanks in advance!

PS: sorry for my worse English :/

I guess you are compiling for "Client profile" and need to compile for the "Full framework".

Ok, but how to that in MS Visual C# 2010?!?

- Display project properties (from contextual menu)
- Application tab
- Target framework
- Select appropriate target framework.

Client profile is a subset of the full framework that essentially contains classes that are mostly used by regular applications.

Oooups. I was wrong. This class is in Client profile.

You simply need to add the appropriate reference to your project. The information is in MSDN documentation (link above). In your case, it will be System.Management assembly that must be added.

as the error suggests, you need two things: a using directive (or a heavy duty keyboard and a lot of time) and a reference.

I think you did the using directive yourself, without having the required reference. My advice is:

1.
Take care of the reference first, use Solution Pane, Add Reference; the MSDN doc on the class of interest tells you which one you need.

2.
Once the ref is in place, Intellisense will guide you trough the using directive.

I only can find this, but what do you mean? Do I miss a piece of code?

Luc Pattyn30-Apr-11 2:59

and that page says:
Assembly: System.Management (in System.Management.dll)

So add the reference to your project as I told you.

Better... but it's a directive, not a statement. Roll eyes | :rolleyes:

If you look here: http://stackoverflow.com/questions/119568/best-practice-to-make-a-multi-language-application-in-c-winforms[^] there is a discussion of the various ways to achieve this. The way you have selected is not necessarily the best: it requires a version of SQLServer to be available to each PC on which your app will run, which may not be possible or desirable.

However:

public void changelanguage(object code) {
    con.Open();
    SqlCommand com = new SqlCommand();
    SqlDataReader dr;
    com.Parameters.AddWithValue("language", code);
    com.CommandText = "SELECT translated FROM translation WHERE languagecode=@language";
    dr=com.ExecuteReader();
    while (dr.Read()) {
        if ((string) dr["textinenglish"] == theWordIWantToTranslate) {
            ...
            }
        }
    }

BTW: Please remember that you are responsible for Close-ing and Dispose-ing all of the SQLCommand and SQLConnection objects you create!

Real men don't use instructions. They are only the manufacturers opinion on how to put the thing together.

Don't forget the @.

And, yeah, that doesn't look like the best way to do it.
