Its your project, not ours. You do it.

This sounds much like a homework assignment. That's why you're getting the answers you are.
And they're right, even if it's not homework. If someone else writes the code for you, it's not your work you're turning in and you don't deserve to get the credit for it. And, you just doing yourself a diservice because you won't be prepared for either the next class, or the next project assignment you get.

Hi, I'm using ado.net to connect to an access database. There are 2 tables "Collezione", bound to dgv1, and "Mazzo", bound to dgv2.
I have a problem with a button (see below for the code) that take a row from dgv1 and copy it in the dataset2 (das2) that is linked to dgv2. When the datarow that I want to copy it's just present in dataset2 I must increase the value in the quantity field in da2 without copy the row.
The code works, but when I copy the 3th different row it stops. Same thing when I try to increase the amount of the second row that I moved :S
Where I'm wrong? Thanks for help!
Here's the code of the button:
Private Sub btnAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAdd.Click
Dim dr As DataRow
dr = das2.Tables("Mazzo").NewRow()
'copy the data from dgv1 to a datarow
Dim i, indexRiga1, colonne1, righeDas2 As Integer
colonne1 = dgv1.ColumnCount - 1
indexRiga1 = dgv1.CurrentRow.Index
If dgv1.SelectedRows.Count > 0 Then
For i = 0 To colonne1
dr(i) = dgv1.Item(i, indexRiga1).Value
Next
dr(11) = 1 'it's the amount index
End If
'if dataSet2 is empty, add the row
righeDas2 = das2.Tables("Mazzo").Rows.Count - 1
If righeDas2 < 0 Then
das2.Tables("Mazzo").Rows.Add(dr)
End If
'if dataSet2 is not empy, try to find if datarow is just present
For i = 0 To righeDas2
If das2.Tables("Mazzo").Rows(i).Item("Nome") = dr(1) And _
das2.Tables("Mazzo").Rows(i).Item("Col") = dr(5) And _
das2.Tables("Mazzo").Rows(i).Item("Tipo") = dr(6) Then
dr(11) = das2.Tables("Mazzo").Rows(i).Item("Giocate") + 1 'increase the amount
das2.Tables("Mazzo").Rows(i).Delete()
das2.Tables("Mazzo").Rows.Add(dr)
End If
Else
das2.Tables("Mazzo").Rows.Add(dr)
End If
Next
End Sub

I'd love to be able to help you, but this code doesn't make any sense and your description of what you need it to do doesn't either.

I try to be more clear...
I have a access database. This database have 2 tables. The first table name is "Collezione" and the second "Mazzo".
In a form I have two datagridview one called "dgv1" and the last "dgv2". The first is bound to datas that are in "Collezione" and the other to data in "Mazzo".
I make a button that copy the report selected by user from dgv1 and add it to dgv2.
the problem is that the code doesn't work

You need to set AutoCompleteMode and AutoCompleteSource to do this. If you set AutoCompleteSource as CustomSource, then AutoCompleteCustomSource should also be populated with list of values.
The word "politics" describes the process so well: "Poli" in Latin meaning "many" and "tics" meaning "bloodsucking creatures."

******This is your windows application or class library project, but it should be "Public Module"******
Public Module TestModule
Public Sub Test()
MsgBox("Test successfully completed")
End Sub
End Module
******Below Code to your Current Project******
Imports System.Reflection
******Use the below code at any event or funtions******
Dim Path As String = "......\"
Dim FileName As String = "XXXX.dll" 'Or "XXXX.exe"
Dim FileAssembly As Assembly = Reflection.Assembly.LoadFile(Path & FileName)
Dim ModuleName As String = "TestModule"
Dim SubName As String = "Test"
Dim RefType As Type = FileAssembly.GetType(FileAssembly.GetName.Name & "." & ModuleName)
Dim MyForm As Form = New Form
RefType.InvokeMember(SubName, BindingFlags.InvokeMethod, Nothing, MyForm, Nothing)
Please tell me the above codes are working or not.......

Write code to copy your files to the appropraite places required, create and the registry keys and values you need, and modify any other configuration files. Shouldn't be too hard, just time consuming.

please give me any sample code
Thanks

I don't have any code that shows how to do it. And seriously, if you can't copy a file in code, you really don't have the skills to make an entire setup for you app.
The only thing I use are MSI installer editors, like InnoSetup, Wise Package Studio, or InstallShield. I just don't believe in reinventing the wheel.

An ASP.NET app is a bit more complicated, and no I don't have any sample setup projects. I just don't go through the MAJOR hassle of reinventing the setup project that comes with Visual Studio.
