hi, I want to change the conecction to my report on ejecution time, I'm working with visual basic 2005 and crystal reports 2008, but I just can't do that because the report(using the crystalreport viewer to see the report) doesn't change the database nor the server, I have been trying with the next code


Imports CrystalDecisions.Shared

Imports CrystalDecisions.CrystalReports.Engine


Dim crTableLogonInfo As New TableLogOnInfo

Dim crConnectionInfo As New ConnectionInfo

next: crvhistorial is the name of the crystalreportviewer

Private Sub SetDBLogonForReport(ByVal myConnectionInfo As ConnectionInfo)

Dim crTableLogonInfos As TableLogOnInfos = Me.crvhistorial.LogOnInfo

For Each myTableLogOnInfo As TableLogOnInfo In crTableLogonInfos

myTableLogOnInfo.ConnectionInfo = myConnectionInfo


End Sub

Private Sub ConfigureCrystalReports()

Dim myConnectionInfo As ConnectionInfo = New ConnectionInfo()

myConnectionInfo.IntegratedSecurity = True

myConnectionInfo.DatabaseName = dll.conexionsql.Database

myConnectionInfo.ServerName = dll.conexionsql.DataSource


End Sub


at the from's load I call the procedure: ConfigureCrystalReports()

    Try this code,

    Imports CrystalDecisions.CrystalReports.Engine
    Imports CrystalDecisions.Web
    Imports CrystalDecisions.Shared
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
            Dim crTables As Tables
            Dim crDatabase As Database
            Dim crConnectioninfo As ConnectionInfo
            Dim crTablellogonInfo As TableLogOnInfo
            Dim rd As New ReportDocument()
            rd.Load("Give here the path of your report")
            crConnectioninfo = New ConnectionInfo()
            crConnectioninfo.ServerName = ""
            crConnectioninfo.DatabaseName = ""
            crConnectioninfo.UserID = ""
            crConnectioninfo.Password = ""
            crDatabase = rd.Database
            crTables = crDatabase.Tables
            For Each crTable As CrystalDecisions.CrystalReports.Engine.Table In crTables
                crTablellogonInfo = crTable.LogOnInfo
                crTablellogonInfo.ConnectionInfo = crConnectioninfo
                crTable.Location = crTable.Location
        CrystalReportViewer1.ReportSource = rd
        End Sub
