Private Sub btnNewStudent_Click(sender As Object, e As EventArgs) Handles btnNewStudent.Click
        Dim name As String = InputBox("Enter the Student's Name", "Name", "Student Name")
        name = StrConv(name, vbProperCase)
        addStudent(name)
        If name = "" Then
            errorMessage("Please Enter a Name")
            lstStudents.Items.Remove("")
        End If
End Sub

When I try to make name into ProperCase, it comes up with an error. I've done a similar thing for items in an array making them UpperCase which works perfectly. But for some reason, this doesn't?

What am I doing wrong xD

Try using Globalization

    Dim ti As Globalization.TextInfo = Globalization.CultureInfo.CurrentCulture.TextInfo
    name = ti.ToTitleCase(name)

Changing Case
