How to fill up these details for connecting a mdf file to crystal report vb2010

[charuwaka]

I have made a crystal report to assign a database to it i created a module with following code and added this module to my form

Collapse | Copy Code
Imports System.Data.SqlClient
Imports System.Data.Sql

Module Module1
Public acscmd As New SqlCommand
Public acsconn As New SqlConnection
Public acsda As New SqlDataAdapter
Public acsds As New DataSet
Public strsql As String
Public Strreportname As String
Sub Connect()
acsconn.ConnectionString = "Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\Items.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True;"
acsconn.Open()
If acsconn.State = ConnectionState.Open Then
MsgBox("Connected")
End If
End Sub

End Module

and in form 2 i dropped a crystal report viewer and crystal report document for that i write this code and a print button
Collapse | Copy Code
Imports CrystalDecisions.CrystalReports.Engine


Public Class Form2


Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
strsql = "select * from Items"
acscmd.CommandText = strsql
acscmd.Connection = acsconn
acsda.SelectCommand = acscmd
acsda.Fill(acsds)
Strreportname = "CrystalReport1"
Dim Strreportpath As String = Application.StartupPath & "\" & Strreportname & ".rpt"
If Not IO.File.Exists(Strreportpath) Then
Throw (New Exception("Unable to load report charu"))

End If

Dim rptdocument As New CrystalDecisions.CrystalReports.Engine.ReportDocument
rptdocument.Load(Strreportpath)
rptdocument.SetDataSource(acsds.Tables(0))
CrystalReportViewer1.ShowRefreshButton = False
CrystalReportViewer1.ShowCloseButton = False
CrystalReportViewer1.ShowGroupTreeButton = False
CrystalReportViewer1.ReportSource = rptdocument

End Sub

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim cryRpt As New ReportDocument
cryRpt.Load("C:\Users\Dell\Desktop\WindowsApplication3\WindowsApplication3\CrystalReport1.rpt")
