Visual Studio嵌入式Crystal报表是否继续提示数据库登录？ [英] Visual Studio Embedded Crystal Report Keeps Prompting Database Login?

问题描述

我正在使用Visual Studio 2005开发带有组合框的表单，该组合框将值传递到嵌入式Crystal报表的参数中。我试图弄清楚为什么每次您尝试使用不同的组合框选择来运行报表时，它总是提示我进行数据库登录。

I'm using visual studio 2005 to develop a form with a combobox passing a value into the parameter of an embedded crystal report. I'm trying to figure out why it keeps prompting me for a database login every single time you try to run the report with a different combobox selection.

这是我的代码：

private Sub Form1_load... 
        Dim ConnName As String
        Dim ServerName As String
        Dim DBName As String
        Dim user As String
        Dim pass As String
        Dim gDBA As ADODB.Connection
        Dim records As ADODB.Recordset
        Dim datver As ADODB.Recordset
        Dim query As String


        '---OPEN THE DATABASE CONNECTIONS
        gDBA = New ADODB.Connection ': gDBA.CursorLocation = adUseServer
        'Added to prevent time out error
        gDBA.CommandTimeout = 1000 : gDBA.ConnectionTimeout = 1000

        gDBA.ConnectionString = "Server=svr13;Database=subscribers;User ID=KViews;Password=Solution;Trusted_Connection=True;"

        gDBA.Open("Data Source=Kaseya;Initial Catalog=subscribers;User Id=KViews;Password=Solution;", "KViews", "Solution")

        records = New ADODB.Recordset

        query = "select distinct groupname from _v_k order by groupname desc"
        'records.ActiveConnection = gDBA.ConnectionString
        records.CursorType = CursorTypeEnum.adOpenForwardOnly
        records.LockType = LockTypeEnum.adLockReadOnly

        records.Open(query, gDBA)
        Do While Not records.EOF
            ComboBox1.Items.Add(records.Fields("groupname").Value)
            records.MoveNext()

        Loop
end Sub 

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim selected As String
        selected = ComboBox1.Text

        Dim cryRpt As New ReportDocument
        cryRpt.Load("C:\Visual Studio 2005\Projects\WindowsApplication1\WindowsApplication1\CrystalReport1.rpt")
        cryRpt.SetDatabaseLogon("KViews", "Solutions", "svr13", "subscribers")


        cryRpt.SetParameterValue("companyname", selected)

        CrystalReportViewer1.ReportSource = cryRpt
        CrystalReportViewer1.Refresh()

    End Sub

我看了之前的帖子包含水晶报告的数据库登录提示

但这不是很有帮助。我找不到CMC禁用提示的位置。

but this wasn't very helpful. I couldn't find where a CMC was to disable the prompt.

有什么想法吗？预先感谢

Any ideas? thanks in advance

推荐答案

将其弄清楚了。以下行不正确

figured it out. the following line was incorrect

    cryRpt.SetDatabaseLogon("KViews", "Solutions", "svr13", "subscribers")

它应该是这样的：

    cryRpt.SetDatabaseLogon("KViews", "Solutions")

the登录提示不再显示。

the login prompt doesn't show up anymore.
