well without knowing more details on your table structure and code this is kind of a vague question.

Basically you are just going to issue sql statements to return a set of customers

SELECT * FROM CUSTOMERS WHERE NAME LIKE 'Jo%'

would return customers name John Joe etc

you would then bind the result set to a grid etc and allow the user to select the customer they want, then you would instantiate a form for that customer ...

I'm ok with the SQL statement, i just want the VB.net source code, uhhmm.. i just cant figure out how the code is, just like a basic searching query.... like a text box... and a button , when i fill in the customerID in the text box, after i click on button , the result will return.

thats a pretty big change done you think ? Imports System
Imports System.Data
Imports System.Data.SqlClient

Module Module1

    Sub Main()
        Dim sConnectionString As String
        ' Modify the following code to correctly connect to your SQL Server.
        sConnectionString = "Password=StrongPassword;User ID=UserName;" & _
                            "Initial Catalog=pubs;" & _
                            "Data Source=(local)"

        Dim objConn As New SqlConnection(sConnectionString)
        objConn.Open()

        ' Create an instance of a DataAdapter.
        Dim daAuthors As _
            New SqlDataAdapter("Select * From Authors", objConn)

        ' Create an instance of a DataSet, and retrieve data from the Authors table.
        Dim dsPubs As New DataSet("Pubs")
        daAuthors.FillSchema(dsPubs, SchemaType.Source, "Authors")
        daAuthors.Fill(dsPubs, "Authors")

        '*****************
        'BEGIN ADD CODE
        ' Create a new instance of a DataTable
        Dim tblAuthors As DataTable
        tblAuthors = dsPubs.Tables("Authors")

        Dim drCurrent As DataRow

        drCurrent("address") = "1956 Arlington Pl."
        drCurrent("city") = "Winnipeg"
        drCurrent("state") = "MB"
        drCurrent("contract") = 1

        Dim dv As DataView = New DataView(tblAuthors)
        dv.RowFilter = "au_fname = 'George'"
        Dim i As Integer
        Dim msg As String = "Found " & dv.Count & " records named George "
        Dim ids As String = ""
        For i = 0 To dv.Count - 1
            ids &= dv(i)("au_id").ToString() & " "
        Next
        MessageBox.Show(Msg & " ids are " & ids)

        'Pass that new object into the Add method of the DataTable.Rows collection.
        tblAuthors.Rows.Add(drCurrent)
        MsgBox("Add was successful.")

        'END ADD CODE    
        '*****************
        'BEGIN EDIT CODE

        drCurrent = tblAuthors.Rows.Find("213-46-8915")
        drCurrent.BeginEdit()
        drCurrent("phone") = "342" & drCurrent("phone").ToString.Substring(3)
        drCurrent.EndEdit()
        MsgBox("Record edited successfully")

        'END EDIT CODE  
        '*****************

        MsgBox("SQL Server updated successfully" & Chr(13) & Chr(13) & "Check Server Explorer to see changes")
    End Sub

End Module

is an example of a quick search (can return multiple records) but I would take a look at the datagrid example for displaying your results.
