How to set database login infos (connection info) for crystal report vb.net?

问题

I am having a little problem getting Crystal Reports to set the logon. I have it working in a number of reports but a couple for some reason have stopped working. Attached is my logon script, I have stepped through it and the logon info is all there after every step.
What is even more unusual is that the report in visual studio will open with information OK

Private Sub cmdPrint_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdPrint.Click
    Dim cryRpt As New ReportDocument
    Dim crTableLogonInfos As New TableLogOnInfos
    Dim crTableLogonInfo As New TableLogOnInfo
    Dim crConnectionInfo As New ConnectionInfo
    Dim crTables As Tables
    Dim crTable As Table
    cryRpt.Load("g:\dt2\rptMusterSheet.rpt")
    With crConnectionInfo
        .ServerName = "SERVERNAME"
        .DatabaseName = "DB NAME"
        .UserID = "sa"
        .Password = "xxxxxxx"
    End With
    crTables = cryRpt.Database.Tables
    For Each crTable In crTables
        crTableLogonInfo = crTable.LogOnInfo
        crTableLogonInfo.ConnectionInfo = crConnectionInfo
        crTable.ApplyLogOnInfo(crTableLogonInfo)
    Next
    CRV1.ReportSource = cryRpt
    CRV1.Refresh()
End Sub

after stepping through I get thisMessage Box

Try this ...

Dim mytableloginfos As New TableLogOnInfos()
mytableloginfos = CRV1.LogOnInfo
For Each myTableLogOnInfo As TableLogOnInfo In mytableloginfos
    myTableLogOnInfo.ConnectionInfo = crConnectionInfo
Next
