The UTF-8 language provides an encoding standard used on the internet for online URLs and e-mail communication. UTF-8 is used in Visual Basic coding for online communications, including links, URL submissions and sending e-mail to users. The Visual Basic language has an internal function that automatically encodes a string to UTF-8 standards. The results from the function return a byte array you can use to code your application.

    Create a byte array. This variable is defined and later used to hold the results of your UTF-8 conversion. The following code creates an array in Visual Basic:

    Dim arrBytes() As Byte

  2. 2

    Create a string that contains a URL. The following code shows you how to create a string for a URL:

    Dim url As String url = ""

    Replace "" with the URL you want to encode.

  3. 3

    Encode the string and store it in the byte array you created. The following code encodes the URL to UTF-8 standards:

    arrByte = Encoding.UTF8.GetBytes(url)

  4. 4

    Print out the results. These results are shown to the user or you can print out results for testing purposes. The following code creates a message box with the results:

    MsgBox arrBytes.ToString()
