In HTML, a marquee is a small section of the browser window that displays text that rolls across the screen. You use the MARQUEE element to create scrolling section. Here in this article, we will also create a marquee function using vb.net.

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 Timer named Timer1, Label named Label1 and NumericUpDown control named NumericUpdown1. You must design your interface like this:



3. Now put this code for your code module.

1. Public
   
   Class
   
   Form1
   
2. 
   
3. Private
   
   Sub
   
   Timer1_Tick(
   
   ByVal
   
   sender As
   
   System.
   
   Object
   
   , ByVal
   
   e As
   
   System.
   
   EventArgs
   
   )
   
   Handles
   
   Timer1.
   
   Tick
   
4. Timer1.
   
   Interval
   
   =
   
   NumericUpDown1.
   
   Value
   
5. Label1.
   
   Left
   
   =
   
   Label1.
   
   Left
   
   -
   
   10
   
6. If
   
   Label1.
   
   Left
   
   <
   
   0
   
   -
   
   Label1.
   
   Width
   
   Then
   
7. Label1.
   
   Left
   
   =
   
   Me
   
   .
   
   Width
   
8. End
   
   If
   
9. End
   
   Sub
   
10. 
    
11. Private
    
    Sub
    
    Form1_Load(
    
    ByVal
    
    sender As
    
    System.
    
    Object
    
    , ByVal
    
    e As
    
    System.
    
    EventArgs
    
    )
    
    Handles
    
    MyBase
    
    .
    
    Load
    
12. Timer1.
    
    Enabled
    
    =
    
    True
    
13. End
    
    Sub
    
14. End
    
    Class
    

Explanation:

We used Timer1 as a control to make the text moved with regards to the time as it ticks. The time interval of our timer1 is to be equal to the value inputted in NumericUpDown1. With the use NumericUpDown1, it can adjust the speed of the marquee text. Then the code below is used for moving text from right to left.

1. Label1.
   
   Left
   
   =
   
   Label1.
   
   Left
   
   -
   
   10
   
2. If
   
   Label1.
   
   Left
   
   <
   
   0
   
   -
   
   Label1.
   
   Width
   
   Then
   
3. Label1.
   
   Left
   
   =
   
   Me
   
   .
   
   Width
   
4. End
   
   If
   

Left properties here is for horizontal location. When the timer starts to tick, the label moved its location by decrementing by 10. If the label's left property is change to 0 then it will be equal to the with of the form making it to scroll again to the left.
