This tutorial will teach you how to create a program that will get the information of the battery of your laptop such as getting its percentage battery and if it is charging or not using vb.net language.

Now, let's start this tutorial!

1. Let's start with creating a Windows Form Application for this tutorial by following the following steps in Microsoft Visual Studio: Go to File, click New Project, and choose Windows Application.

2. Next, add only one ProgressBar on the Form and a Timer on it. Design like this:



3. Now, let's do the coding.

We will first code for the Tick Event of the Timer.

Declare first the variables for the System Information of the Power Status.

1. Dim
   
   psBattery As
   
   PowerStatus =
   
   SystemInformation.
   
   PowerStatus
   
2. Dim
   
   perFull As
   
   Single
   
   =
   
   psBattery.
   
   BatteryLifePercent
   

Get the Power status that is multiplied by 100.

1. If
   
   perFull *
   
   100
   
   >
   
   100
   
   Then
   
2. ProgressBar1.
   
   Value
   
   =
   
   100
   
3. ElseIf
   
   perFull *
   
   100
   
   <
   
   100
   
   Then
   
4. ProgressBar1.
   
   Value
   
   =
   
   perFull *
   
   100
   
5. End
   
   If
   

Now, we will get the percentage of the battery and determine if it is charging or not.

1. If
   
   psBattery.
   
   PowerLineStatus
   
   =
   
   PowerLineStatus.
   
   Online
   
   Then
   
2. Me
   
   .
   
   Text
   
   =
   
   "Battinfo - "
   
   &
   
   perFull *
   
   100
   
   &
   
   "%"
   
   &
   
   " charging!"
   
3. ElseIf
   
   psBattery.
   
   PowerLineStatus
   
   =
   
   PowerLineStatus.
   
   Offline
   
   Then
   
4. Me
   
   .
   
   Text
   
   =
   
   "Battinfo - "
   
   &
   
   perFull *
   
   100
   
   &
   
   "%"
   
   &
   
   " don´t charging"
   
5. End
   
   If
   

Lastly, just enable the Timer in your Form_Load.

1. Private
   
   Sub
   
   Form1_Load(
   
   ByVal
   
   sender As
   
   System.
   
   Object
   
   , ByVal
   
   e As
   
   System.
   
   EventArgs
   
   )
   
   Handles
   
   MyBase
   
   .
   
   Load
   
2. Timer1.
   
   Enabled
   
   =
   
   True
   
3. End
   
   Sub
