My code will not capitalize first letter of line

[Jesi523]

My input text from a .txt file is this is the first line this is the second line this is the third line I need to capitalize the first letter of each word by placing it in a textbox, I have the following code: Dim aString As String = My.Computer.FileSystem.ReadAllText("input.txt") Dim stringReturn As String If My.Computer.FileSystem.FileExists("input.txt") Then Me.xInputTextBox.Text = (Convert.ToString(aString.ToLower)) End If Do While (aString.IndexOf(Space(2)) >= 0) aString = aString.Replace(Space(2), Space(1)) Loop Dim caparray() As String = (aString.Split(" " & "ControlChars.NewLine")) For I As Integer = 0 To caparray.Length - 1 If caparray(I).Length = 1 Then caparray(I) = caparray(I).ToUpper Else ' ***join them back together caparray(I) = caparray(I).Substring(0, 1).ToUpper & caparray(I).Substring(1).ToLower End If Next stringReturn = String.Join(" ", caparray) Me.xInputTextBox.Text = (stringReturn.ToString) My output is then This Is The First Line this Is The Second Line this Is The Third Line It will not capitalize the first letter of the second and third line. Can someone please tell me what I am doing wrong? Thanks, Jesi

There is a newline but no space between Line and this, so to your algorithm they are just one word! A simple debug session would have told you that. You will have similar problems with punctuation: "aha" will be seen as a word starting with " not a. :)

Hi Jesi,

as always: 1. define the requirements as accurately as possible (what is a word, which words need capitalization, ...) 2. analyze, design, implement, test 3. iterate until satisfied. :)

stringReturn = String.Join(" ", caparray) I do not have your answer but what does this String.Join do, is it joining the first line to the second line and so on? Can you use vbcrlf to go to the next line or 'proper case' instead of 'upper case'.
