Here, the old VB6 function StrConv is used to attempt to convert the words to proper case, let’s look at Figure 3 to see if it worked: If you look closely though, you will notice that the words that are entirely in Upper case have not been changed… Let’s hope Button3 works better! Private Sub Button3_Click(sender As Object, e As EventArgs) _ĭim strOutput As String = StrConv(strInput, _ The result after clicking Button2 is shown in Figure 2: Here, you make use of the CultureInfo object to help set the case for the words. Private Sub Button2_Click(sender As Object, e As EventArgs) _ This is not what we want! If all the words were completely in lower case, the code would have worked. The result after clicking Button1 is shown in Figure 1:Īs you can see, the code behind Button1 fails to change all the words to proper case and it cuts off some text. You will be using it with the other buttons as well. I have made use of the following text inside the TextBox to see if this code would work in a real-world situation: ThIS iS really REALLY a SiMpLe test for YOU to SeE This code tries to emulate some string functions by looping through each character and attempting to change it to an uppercase letter.

StrOutput = (strOutput & ' ' & strInput(j)) StrInput(i).Substring(1, strInput(i).Length - 1))įor j As Integer = 0 To strInput.Rank + 1 StrInput(i) = (strInput(i).Substring(0, 1).ToUpper & _ The CodeĪdd the following code behind Button1: Private Sub Button1_Click(sender As Object, e As EventArgs) _įor i As Integer = 0 To strInput.Rank + 1

Do not worry too much about the names for the objects this example makes use of the default names. On the Form, add four buttons and one TextBox. Now, there are various quick ways to do this, but to figure out which method is the best is what you should be looking for.Ĭreate a new Visual Basic Windows Forms application. This is known as Title Case or Proper Case. In this article, I will show you different ways to change each letter of a word in a sentence to upper case. It is, however, up to us (as developers) to determine the correct way to achieve our goals. As you may or may not know: strings are strange creatures! I say so because there are so many ways to do a certain task.
