    Problem with Crystalreports

    Problem with reports
    I have a problem

    I created
    Vb.net project 2015 with sql

    After I cleared the project and tried the project at the client


    An error appears when the reports are shown by the crystal Report

    Code:
          Dim rpt As New WaznRep
    
           For Each DSC As CrystalDecisions.Shared.IConnectionInfo In rpt.DataSourceConnections
               (DSC.SetLogon(muser, mpass)
               DSC.SetConnection(mserver, mdb, False)
           Next
           ReportV1.CrystalReportViewer1.ReportSource = rpt
           ReportV1.ShowDialog()

    It does not connect to the database
    This message appears and the name of the database is empty

    But from my device everything works

    And I used the last code to connect to the database

    Code:
            Dim rpt1 As New WaznRep
            Dim ConInfo As New CrystalDecisions.Shared.TableLogOnInfo
            ConInfo.ConnectionInfo.ServerName = mserver
            ConInfo.ConnectionInfo.DatabaseName = mdb
            ConInfo.ConnectionInfo.UserID = muser
            ConInfo.ConnectionInfo.Password = mpass
            rpt1.Database.Tables(0).ApplyLogOnInfo(ConInfo)
            ReportV1.CrystalReportViewer1.ReportSource = rpt1
            ReportV1.CrystalReportViewer1.RefreshReport()
            ReportV1.ShowDialog()
