How are you supposed to get the input - word by word in a loop or in one line?
What are your errors? Can you post the code?

[programming02]

Public Class Form1

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim arr(30) As String
Dim line As String

For i As Integer = 0 To 30
arr(i) = InputBox(i)
Next

For i As Integer = 0 To 30
Label1.Text &= arr(i) & vbCrLf


Next

For i As Integer = 0 To 30
If (arr(i) = "End") Then

Next


End Sub
End Class

[Thomas1965]

Try this:

Public Class Form1

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load

  Dim Words(30) As String
  Dim WordCount As Integer = 0
  Dim Input As String = ""

  While (WordCount < 30 AndAlso Input <> "End")
    Input = InputBox("Enter Word " & CStr(WordCount), "Input")
    If Input = "End" Then
      Exit While
    Else
      Words(WordCount) = Input
      WordCount = WordCount + 1
    End If
  End While

  Label1.Text = String.Join(" ", Words, 0, WordCount)

End Sub
End Class

[Thomas1965]

How do you want to show them - Label, TextBox, MessageBox.....????????????????

[programming02]

show them in Label

[programming02]

Trim method in vb.net

my code :

Public Class Form1

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Dim name As String

name = TextBox1.Text
Label2.Text = name.Trim & name


End Sub
End Class

--------------------------------------------
input: sa ra


output : sara sarasara sara

show them in Label please;

[Thomas1965]

Trim removes only leading and trailing spaces in a string. If you want to delete spaces in the middle you need to use the Remove function.

[Thomas1965]

Maybe sth. like that:

Label2.Text = "Purchases: " & Purchase.ToString() & vbCrLf & "Total: " & Total.ToString()
