For this article, we will create a program that will count the number of words in a TextBox. But we will just use the RichTextBox instead of TextBox :)

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 one RichTextBox named RichTextBox1 and a Button named Button1 labeled as "Get Number of Words". You must design your layout like this:



3. Now put add this code for your code module. This code is for Button1_Click. This will trigger to count the number of words in your RichTextBox.

1. Private
   
   Sub
   
   Button1_Click(
   
   ByVal
   
   sender As
   
   System.
   
   Object
   
   , ByVal
   
   e As
   
   System.
   
   EventArgs
   
   )
   
   Handles
   
   Button1.
   
   Click
   
2. Dim
   
   strInput As
   
   String
   
3. strInput =
   
   RichTextBox1.
   
   Text
   
4. Dim
   
   strSplit(
   
   )
   
   As
   
   String
   
5. strSplit =
   
   strInput.
   
   Split
   
   (
   
   CChar
   
   (
   
   " "
   
   )
   
   )
   
6. MsgBox
   
   (
   
   "Number of words: "
   
   &
   
   strSplit.
   
   Length
   
   )
   
7. End
   
   Sub
   

Explanation:

We have initialized variable strInput as String to hold the value inputted in the RichTextBox. We also declare variable strSplit as string to split the words inputted in the RichTextBox. We use the CChar function to find the spacing of the text. Then we create a MessageBox to display the number of words using the Length function.
