Real-time CPU temperature reading using OpenHardwareMonitorLib

Real-time CPU temperature reading using OpenHardwareMonitorLib


From the OpenHardwareMonitor.Org website, Open Source Code (C #) is used to read the temperature and voltage levels on the motherboard according to ChipSet.

Real-time CPU temperature reading using OpenHardwareMonitorLib is created using visual Basic .NET language.

First, find the number of CPUs that are available on the PC. Then, count how many cores are in the motherboard. Finally, display all the results in the ListView Control.

Then will create a dynamic progress bar (@Run Time) based on the number of CPU cores. Display the temperature in real-time the process of refreshing the temperature is at BackgroundWorker The timing is determined by Timer1 Control.

This project began when I intended to develop a tiny tool that used the free source OpenHardwareMonitorLib.dll to display the CPU temperature in a corner of the desktop (). Here’s the link to the website.

This library contains a wealth of hardware data, including numerous system temperatures that may be accessed via a Windows Management Interface (WMI).

However, I found the limited documentation confusing and had better luck directly using OHM’s public class enumerations, with the key being to call the Update methods for items and subitems correctly before attempting to enumerate them.

This timing is automatically turned on / off with a Boolean variable.

Thank You.

I hope this simple application will help you.

Frequently Asked Questions

How does this VB.NET project work?

Built with VB.NET WinForms (.NET Framework 4.5+) and SQL Server backend. Standard structure: Form designer to code-behind event handlers to ADO.NET data access layer to SQL Server. Login form for auth. Ready to extend for BSIT capstone scope.

What Visual Studio and SQL Server versions does this VB.NET project require?

Most projects use VB.NET WinForms on .NET Framework 4.5+ with SQL Server 2012 Express or higher. To run: install Visual Studio 2019 / 2022 (Community is free) with the ‘Desktop development with .NET’ workload, install SQL Server Express + SSMS, open the .sln file, build, run.

How do I set up the database for this VB.NET project?

Open SQL Server Management Studio (SSMS) and connect to your SQL Server (e.g. localhost\SQLEXPRESS). Right-click Databases, choose Restore Database OR New Database then import the included .sql script. Update the connection string in App.config (or in code-behind Module) with your server name + credentials. Rebuild and run.

Can I use this VB.NET project for a BSIT capstone or thesis?

Yes, VB.NET is one of the most accepted languages by Philippine BSIT panels. Extend it: add role-based access (admin/staff/customer login redirect), Crystal Reports or RDLC reports, dashboards with Chart control, audit log, multi-branch support. Pair with Chapter 1-5 documentation matching your panel’s rubric.

Why am I getting ‘connection error’ or ‘cannot find SQL Server’?

Three common VB.NET issues: (1) Connection error: SQL Server isn’t running. Open SQL Server Configuration Manager and verify SQL Server (SQLEXPRESS) service is started. (2) Wrong server name in connection string. Try .\SQLEXPRESS, (local)\SQLEXPRESS, or your machine name. (3) Login failed: SQL Server is set to ‘Windows-only’ authentication. Switch to Mixed Mode in SSMS Server Properties, Security.

Where can I find more VB.NET projects with source code?

Browse the VB.NET Projects hub for the full library. For C# WinForms alternatives see C# Projects. For ASP.NET web alternatives see ASP.NET Projects. For BSIT capstone idea lists see 150 Best Capstone Project Ideas.
