Below is my code to enter data into an array and retrieve the information
Entering the data seems to have no problems but when I click the button to retrieving the information it just presents 0's in the text box.
Public Class Form1
Dim Array(20) As String
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim counter As Integer
For counter = 0 To ListBox1.Items.Count - 1
Array(counter) = txtEnterMarks.Text(counter)
Next
Label1.Text = "omfg"
End Sub
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
For counter = 0 To Array.Length - 1
ListBox1.Items.Add(Array(counter))
Next
End Sub
End Class

Again .. try this different answer
Structure Student
Dim Name As String
Dim Mark As Integer
End Structure
To save your input in it :
Dim StudentsInfo as New List(Of Student)
Dim si As New Student
si.Name = txtEnterName.Text
si.mark = val(txtEnterMark.Text)
StudentsInfo.Add(si)
To get value from StudentsInfo
txtEnterName.Text = StudentsInfo(0).Name
txtEnterMark.Text = StudentsInfo(0).mark.ToString
About preserve it To ListView .. Again .. Try Mr. Google ...
