设置reportviewer参数值时指针错误无效 [英] Invalid pointer error on setting reportviewer parameter values

问题描述

您好

我正在使用与VS2005捆绑在一起的水晶报告版本，网页报告查看器上的所有内容都能正常运行，直到我设置任何参数值。然后我收到以下错误：

 I'm using the crystal reports version bundled with VS2005, everything on the web reportviewer works perfectly until I set any parameter values. I then get the following error:

消息："无效指针"，

来源：rptcontrollers.dll，

我的rptcontroller DLL版本是：10.2.0.1093

My rptcontroller DLL version is: 10.2.0.1093

以下代码是我如何设置参数：

The following code is how I set the parameters:

Pa rameterFields pfsReport = new ParameterFields （）;

ParameterFields pfsReport = new ParameterFields();

ParameterDiscreteValue pdvReport = new ParameterDiscreteValue （）;

ParameterDiscreteValue pdvReport = new ParameterDiscreteValue();

pdvReport.Value = oReportParameterValues.ToString（）;

pdvReport.Value = oReportParameterValues.ToString();

ParameterField pfdReport = new ParameterField （）;

ParameterField pfdReport = new ParameterField();

pfdReport.CurrentValues.Add（pdvReport）;

pfdReport.CurrentValues.Add(pdvReport);

pfsReport.Add（pfdReport）;

pfsReport.Add(pfdReport);

rpvView.ParameterFieldInfo = pfsReport; // rpvView = ReportViewer

rpvView.ParameterFieldInfo = pfsReport; //rpvView = ReportViewer

rpvView.ReportSource = rptReport; // rptReport = ReportDocument

rpvView.ReportSource = rptReport; //rptReport = ReportDocument

rpvView.RefreshReport（）;

rpvView.RefreshReport();

有没有人得到我可以解决这个问题的任何答案，或者可能是另一种方法来添加不会产生相同错误的参数值？

Has anybody got any answers to how I can fix this, or maybe another way to add the parameter values that doesn't give the same error?
