Dim spyinfo As Array

dispscreen.spylist.Items.Add(fstnam.Text)
Dim i As Integer = 0
i = dispscreen.spylist.Items.Count - 1
dispscreen.spylist.Items.Item(i).SubItems.Add(surnam.Text)
dispscreen.spylist.Items.Item(i).SubItems.Add(age1.Text)

' this part of the sub takes information that has been inputed into edit screen when the edit button has been clicked and replaces it by what was previously selected
If Me.Text = "Edit" Then
'dispscreen.spylist.Items(dispscreen.spylist.SelectedIndices.Item(0))
Dim i As Integer = 0

i = dispscreen.spylist.Items.Count - 1

dispscreen.spylist.Items.Item(i).SubItems.Add(cdenam.Text)
dispscreen.spylist.Items.Item(i).SubItems.Add(specskil.Text)
dispscreen.spylist.Items.Item(i).SubItems.Add(sex.Text)
dispscreen.spylist.Items.Item(i).SubItems.Add(distinmar.Text)
dispscreen.spylist.Items.Item(i).SubItems.Add(swbank.Text)

Me.Hide()
End If
End If
'this part of the sub sets the input screen back to a blank value it basically clears the formadd back to a blank state ready for the next spy to be added
fstnam.Text = ""
surnam.Text = ""
age1.Text = ""
cdenam.Text = ""
specskil.Text = ""
sex.Text = ""
distinmar.Text = ""
swbank.Text = ""
End Sub

First, post using the VBCODE /VBCODE tags it makes it easier to read

second, i dont think i really understand what you want.. whats not happening or any errors you're getting?

seems like you're trying to select an edit button and bring that "spys" info to the listview? where are you storing all this information?

VB Code:

Private Sub bttnadd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles bttnadd.Click
' this sub takes the informaiton that the user has inputed into frmaddedit and adds it to the list view under its approprate heading in spylist in the form display screen
If Me.Text = "Add" Then
Dim spyinfo As Array
 
dispscreen.spylist.Items.Add(fstnam.Text)
Dim i As Integer = 0
i = dispscreen.spylist.Items.Count - 1
dispscreen.spylist.Items.Item(i).SubItems.Add(surnam.Text)
dispscreen.spylist.Items.Item(i).SubItems.Add(age1.Text)
dispscreen.spylist.Items.Item(i).SubItems.Add(cdenam.Text)
dispscreen.spylist.Items.Item(i).SubItems.Add(specskil.Text)
dispscreen.spylist.Items.Item(i).SubItems.Add(sex.Text)
dispscreen.spylist.Items.Item(i).SubItems.Add(distinmar.Text)
dispscreen.spylist.Items.Item(i).SubItems.Add(swbank.Text)
 
Me.Hide()
Else
' this part of the sub takes information that has been inputed into edit screen when the edit button has been clicked and replaces it by what was previously selected
If Me.Text = "Edit" Then
'dispscreen.spylist.Items(dispscreen.spylist.SelectedIndices.Item(0))
Dim i As Integer = 0
 
i = dispscreen.spylist.Items.Count - 1
dispscreen.spylist.SelectedItems.Item(i).SubItems.Add(fstnam.Text)
dispscreen.spylist.SelectedItems.Item(i).SubItems.add(surnam.Text)
dispscreen.spylist.Items.Item(i).SubItems.Add(age1.Text)
dispscreen.spylist.Items.Item(i).SubItems.Add(cdenam.Text)
dispscreen.spylist.Items.Item(i).SubItems.Add(specskil.Text)
dispscreen.spylist.Items.Item(i).SubItems.Add(sex.Text)
dispscreen.spylist.Items.Item(i).SubItems.Add(distinmar.Text)
dispscreen.spylist.Items.Item(i).SubItems.Add(swbank.Text)
 
Me.Hide()
End If
End If
'this part of the sub sets the input screen back to a blank value it basically clears the formadd back to a blank state ready for the next spy to be added
fstnam.Text = ""
surnam.Text = ""
age1.Text = ""
cdenam.Text = ""
specskil.Text = ""
sex.Text = ""
distinmar.Text = ""
swbank.Text = ""
End Sub

In button edit click event do:
1. check to see if any thing is selected in the listview.
2. If something is selected... Pull that item's data (should include the index of the selected item too in case your user select multiple items) and pass it to the 2nd form where the user will do the edit.
3. In the 2nd form load event, load the data passed from the main form accordingly.
4. Now that the user have done editing and close the form... Back in the main form, you need to read back the info from the closing form including the index number, and update your listview item accordingly.
If you don't know how to do any of these, please say so... I'll be glad to give help where I can.

hi there, sorry i have no idea what to do with that can you help

Here a quick example I just made... Hope it helps.
Form1 has a ListView1, and a Button1 (click to edit selected items in ListView1)

VB Code:

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
 
        'This is used to load some dummy data to listview1 for testing purposes
        'ListView1 properties are set to: View = Details, FullRowSelect = True, MultiSelect = True
        ListView1.Columns.Add("First", 60, HorizontalAlignment.Left)
        ListView1.Columns.Add("Last", 60, HorizontalAlignment.Right)
        Dim itm As ListViewItem
        For i As Integer = 0 To 5
            itm = New ListViewItem(New String() {"First_" & i, "Last_" & i})
            ListView1.Items.Add(itm)
        Next
    End Sub
 
    Private Sub Button1_Click(ByVal sender As System.Object, _
                              ByVal e As System.EventArgs) Handles Button1.Click
        'Create a new instance of Form2 and pass values to it for each
        'selected item in listview1
        For Each itm As ListViewItem In ListView1.SelectedItems
            Dim frm2 As New Form2
            'Pass the index of selected item to this instance of Form2
            frm2.ItemIndex = itm.Index
            'Pass the actual item to this instance of Form2
            frm2.LvwItem = itm
            'Set the current instance of Form1 as the Owner of frm2 
            frm2.Owner = Me
            'Show this instance of Form2
            frm2.Show()
        Next
    End Sub

And the code for Form2... Form2 has only 2 textboxes (because an item in Form1's ListView1 has only 2 subitems...)

VB Code:

Private _ItemIndex As Integer
    Private _LvwItem As ListViewItem
 
    Public Property ItemIndex() As Integer
        Get
            Return _ItemIndex
        End Get
        Set(ByVal Value As Integer)
            _ItemIndex = Value
        End Set
    End Property
 
    Public Property LvwItem() As ListViewItem
        Get
            Return _LvwItem
        End Get
        Set(ByVal Value As ListViewItem)
            _LvwItem = Value
        End Set
    End Property
 
    Private Sub Form2_Load(ByVal sender As Object, _
                           ByVal e As System.EventArgs) _
                           Handles MyBase.Load
        If Not _LvwItem Is Nothing Then
            TextBox1.Text = _LvwItem.SubItems(0).Text
            TextBox2.Text = _LvwItem.SubItems(1).Text
        End If
 
    End Sub
 
    Private Sub Form2_Closing(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles MyBase.Closing
        'Create a new listViewItem with the updated info from textboxes
        'and assign it back to the same listview1 item in Form1 
        Dim lvwItm As New ListViewItem(New String() {TextBox1.Text, TextBox2.Text})
        CType(Me.Owner, Form1).ListView1.Items(_ItemIndex) = lvwItm
    End Sub

Thanks problem solved
