在Visual Studio 2019中的客户端计算机中，Crystal Report SP26 SetDataSource（）方法失败 [英] Crystal Report SP26 SetDataSource() Method failed in computers of clients in Visual Studio 2019

问题描述

我正在使用Visual Studio 2019和Crystal Report Service Pack 26.我的代码将数据读取到ADO.NET数据集中，并将这些数据设置为报告的数据源。在Visual Basic.Net中是这样的：

​I'm working on Visual Studio 2019 and Crystal Report Service Pack 26. My code read data into ADO.NET dataset and I set those datases as datasourse of my reports. something like this in Visual Basic.Net:

    Dim ds1 As New DataSet1()

    Dim myRep As New CrystalReport1
    taAccArticleFields_TBL.Fill(ds1.AccArticleFields_TBL)
    myRep.SetDataSource(ds1)
    crvReport.ReportSource = myRep

当我通过VS运行程序时，一切都很好，并且报告显示没有错误。但是，当我想在安装了CR26运行时的另一台计算机上运行程序时，在调用SetDataSource方法获取报告时出现错误，如下所示：

When I run program through VS all is good and reports show without error. But when I want to run my program on another computer which only has CR26 runtime installed, it gives an error on calling SetDataSource method for report as below:

System.Runtime.InteropServices.COMException (0x800002CD): Error in File temp_04020c6d-5b84-40d9-8558-bf87b6d5e554 4840_5464_{1C1D3ACF-9F25-45E2-B0EE-BB77F1DDA6B6}.rpt: Failed to load database information. 
at CrystalDecisions.ReportAppServer.Controllers.DatabaseControllerClass.ReplaceConnection(Object oldConnection, Object newConnection, Object parameterFields, Object crDBOptionUseDefault) 
at CrystalDecisions.CrystalReports.Engine.Table.SetDataSource(Object val, Type type) 
at CrystalDecisions.CrystalReports.Engine.ReportDocument.SetDataSourceInternal(Object val, Type type)

我遇到这与我编写的任何程序有关。有人有解决这个问题的想法吗？

I encounter this with any program I write. Does anyone have idea to solve this?

推荐答案

感谢@Julie，我发现缺少的文件需要使用Crystal运行ADO.Net报告。报告SP26。
不幸的是，在安装SP26运行时时，它不会复制需要Crystal Report从ADO.Net数据集中加载数据的 crdb_adoplus.dll 文件。

Thanks to @Julie I found missing file need to run ADO.Net report using Crystal Report SP26. Unfortunately, When you install SP26 run-time it doesn't copy crdb_adoplus.dll file which need to Crystal Report to load data from ADO.Net dataset.

这是解决方案：

• 在32位操作系统中：您必须从以下文件夹将crdb_adoplus.dll文件从开发人员计算机复制到客户端计算机：

• In 32bit operating systems: you have to copy crdb_adoplus.dll file from developer computer to client machine from following folder:

C：\Program Files（x86）\SAP BusinessObjects\Crystal Reports适用于.NET Framework 4.0\Common\SAP BusinessObjects Enterprise XI 4.0\win32_x86

C:\Program Files (x86)\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\Common\SAP BusinessObjects Enterprise XI 4.0\win32_x86

在64位操作系统中：从以下文件夹将crdb_adoplus.dll文件从开发人员计算机复制到客户端计算机：

In 64bit operating systems: you have to copy crdb_adoplus.dll file from developer computer to client machine from following folder:

C：\Program Files（x86）\SAP BusinessObjects\Crystal Reports for。 NET Framework 4.0-常见-SAP BusinessObjects Enterprise XI 4.0-win64_x64

C:\Program Files (x86)\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\Common\SAP BusinessObjects Enterprise XI 4.0\win64_x64

它可以正常工作。我希望SAP在以后的Service Pack中解决此问题。

And it work correctly. I hope SAP resolve this problem in the future service pack.
