Question

我有一个Windows应用程序,将《2008年晶报告》用作报告工具。在很长一段时间里,它的工作被罚款,但昨天,当我试图装上任何报告时,我发现这一错误:

CrystalDecisions.CrystalReports.Engine.DataSourceException: Unknown Query Engine Error
Error in File C:UsersMagdyAppDataLocalTemp
pt_Stock_Cost {DC276D4F-79F4-43B9-8168-24E6B7BF490A}.rpt:

   at CrystalDecisions.CrystalReports.Engine.ReportDocument.SetDataSourceInternal(Object val, Type type)

   at Diamonds.UIL.Forms.frm_ReportViewer.Load_Report(String File_FullPath, DataSet DS) in E:DevelopmentBitcoDiamondProjectDiamond 2.0.1DiamondsUILReportsFormsViewerfrm_ReportViewer.cs:line 256

这里使用的代码I用于报告的数据来源:

DataSet ds = new DataSet();
reportDocument_.Load(File_FullPath);
reportDocument_.SetDataSource(ds);

d> 可以是分类数据组。

在有些争.之后,我发现了一些结果,即我应该有网络服务,在窗户中使用轮椅。虽然我认为这是为了网络应用,而不是窗口。我在尝试时双倍,而上述两倍例外,但都没有帮助。

I m using Visual Studio 2010, C# 4.0, Windows Application

Any ideas what could be wrong?

Answer 1

If you compile in VS2010 (or VS2012) on a Win7 machine, try adding the following to the app.config:

<startup useLegacyV2RuntimeActivationPolicy="true">
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
</startup>

如果这种工作(如我的机器)在VS2010年进行温XP机器的汇编。
