how to find all data in my first listview to another

Can you please explain what you mean by this?

Comments
and I thought I was the only one who din not comprehend that

i have 2 excel files namely "Account.xls" and the other one is "Call and Visit.xls" all the data in "Account.xls" is go to listview1 and the "Call and Visit.xls" data go to the Listview2

in the picture i upload you will see they have both an "AM" Column Name..

I want to find all the "AM" in my Listview1 to the Listview2 any idea?

I want to find all the "AM" in my Listview1 to the Listview2

Still unclear. Do you mean you want to find all AM values from ListView1 that exist in ListView2 or do you want to find all AM values from ListView2 that exist in ListView1? Or do you want something else entirely?

Whatever it is that you want, how do you want to present the results?

i want to find all AM values from ListView1 that exist in ListView2

after finding all the AM in the listview1 to listview2 i will sum all their calls and visits by Month (January to December)

My take is you want to take the items in column 1 in listview1 and add them to column 1 in listview2, and that both columns show "AM". This code will do that:

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        For I = 0 To ListView1.Items.Count - 1
            ListView2.Items.Add(ListView1.Items(I).Text)
        Next

    End Sub

A warning this code isn't generic to moving text from any column to another. This will only move item.text from listview.column(0) to listview.column(0)

No its not add..

i already have the data in Column1 in the listview2

if the **Column1 in Listview1** is exist in the **Column1 in Listview2** then
'execute the code

it is something related into this code but i try to figure it out.

Dim query As String
For Each item As ListViewItem In ListView1.Items
query = "Select * from [Calls and Visits$] where AM like '" & item.SubItems(1).Text & "%'"
'execute the query and do something with the results
Next

after finding all the AM in the listview1 to listview2 i will sum all their calls and visits by Month (January to December)

You already have that data in ListView2.

Yes i already have it but i want to do to find a specific "AM" from the listview1 to listview2

Maybe this is closer to what you want

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim NewItems As New List(Of ListViewItem)
        For I = 0 To ListView1.Items.Count - 1
            For J = 0 To ListView2.Items.Count - 1
                If ListView2.Items(J).Text = ListView1.Items(I).Text Then
                    NewItems.Add(ListView1.Items(I))
                End If
            Next
        Next
        MessageBox.Show(NewItems.Count)
    End Sub

This creates a list of items from listview1 that exist in listview2.

Just a guess, but I think Zick may be a user of google translate or something similar. Hence the odd wording.

Based on this:

Dim query As String
For Each item As ListViewItem In ListView1.Items
query = "Select * from [Calls and Visits$] where AM like '" & item.SubItems(1).Text & "%'"
'execute the query and do something with the results
Next

and this

after finding all the AM in the listview1 to listview2 i will sum all their calls and visits by Month (January to December)

I believe that he wants to search ListView2 for each "AM" entry in ListView1 and compute a yearly "Call" and "Visits" total per "AM" entry.

Perhaps Something Like this:

Hi @TnTinMN thanks for the reply i already got the code for this thanks to @tinstaffl

your code work perfectly fine and i can use it for the future works :)
Thanks again.
