VB.Net Project Application Settings Store and Retrieve Information
In this tutorial, you will learn how to use VB.Net Project Application Settings usefulness in terms of storing and retrieving data without the use of mySQL or SQL Server databases.
Create a new VB.Net Windows Application Form and add these objects to your interface. (follow the example image).
Retrieving Application Settings
Next, on the Solution Explorer, right click the name of your project and go to Properties. After going to Properties tab, at the left side tab, select Settings and add the following settings for us to retrieve its value depending on the called name setting. (see image below).
On your Form1, double click the form and add this line of code to your Form1.
[vbnet]
Public Class Form1
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
TextBox1.Text = My.Settings("Website")
TextBox2.Text = My.Settings("Blogsite")
End Sub
End Class
[/vbnet]After adding this line of code, try to run your project. The expected output should be like the example image below.
Storing Application Settings
We are now going to create a button that will serve as the storing code or updating our application setting’s value.
Add a new button and double click it for us to insert this line of code.
[vbnet]
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
My.Settings("Website") = TextBox1.Text
My.Settings("Blogsite") = TextBox2.Text
My.Settings.Save()
End Sub
[/vbnet]After that, try to change your current Website and Blogsite application settings and click the Save button.
After saving the values, try to exit your program and run it again. You will notice that your updated values are loaded instead of our set values.
