Protected Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
      Dim cn As New SqlConnection("server=192.168.2.200;database=stupremat;user=adm;password=Stupremat0@")
      Dim stupremat2 As New SqlConnection("server=192.168.2.200;database=stupremat;user=adm;password=Stupremat0@")
      Dim stupremat As New SqlConnection("server=192.168.2.200;database=stupremat;user=adm;password=Stupremat0@")
      Dim substitution3 As New SqlConnection("server=192.168.2.200;database=SUBSTITUTION_SERVER;user=adm;password=Stupremat0@")
      Dim tabEmp As New DataTable
      tabEmp.Columns.Add("Emplacement")
      tabEmp.Columns.Add("Articles")
      tabEmp.Columns.Add("Substitution")
      tabEmp.Columns.Add("Designation")
      tabEmp.Columns.Add("Stock")
 
      If cn.State = ConnectionState.Open Then
          cn.Close()
      End If
 
      cn.Open()
 
      Dim cmd2 As New SqlCommand("SELECT [DP_No],[DP_Code],[DP_Intitule],[DP_Zone] FROM [STUPREMAT].[dbo].[F_DEPOTEMPL] where DP_Intitule = 'A0013' order by DP_Intitule", cn)
      Dim sqldata As New SqlDataAdapter(cmd2)
      sqldata.Fill(tabEmp)
 
      Dim rpt As New CRDemo
      rpt.SetDataSource(tabEmp)
      CrystalReportViewer1.ReportSource = rpt
      CrystalReportViewer1.DataBind() 
      cn.Close() 
  End Sub
