Failed to open the connection [Crystal Report]
提问by Harvey
I'm receiving this error when I load the form that uses Crystal Report:
我在加载使用 Crystal Report 的表单时收到此错误：
Failed to open the connection Details: [Database Vendor Code: 17] Failed to open the connection. ReportMonthly {...}.rpt Details: [Database Vendor Code: 17]
无法打开连接详细信息：[数据库供应商代码：17] 无法打开连接。ReportMonthly {...}.rpt 详细信息：[数据库供应商代码：17]
I've researched on google about this error and so I find this site. I tried the steps or the instructions there but it didn't work meaning the same error.
我在谷歌上研究过这个错误，所以我找到了这个网站。我尝试了那里的步骤或说明，但没有奏效，这意味着同样的错误。
Here is the part of the code in my form:
这是我表单中的代码部分：
Private Sub FRViolators_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.ShowReport(My.Application.Info.DirectoryPath & "\ReportMonthly.rpt")
End Sub
Public Sub ShowReport(ByVal strReportPath As String)
Dim rptDoc As CrystalDecisions.CrystalReports.Engine.ReportDocument
rptDoc = New ReportDocument
rptDoc.Load(strReportPath)
CrystalReportViewer1.ReportSource = rptDoc
CrystalReportViewer1.Refresh()
End Sub

Create the connection manual
创建连接手册
rptDoc.Load(strReportPath)
rptDoc.SetDatabaseLogon("user", "password", "host", "dbname");
CrystalReportViewer1.ReportSource = rptDoc
CrystalReportViewer1.Refresh()
