  Hello

  We’ve encounter a problem with Active Reports 9.2 and 11.3 (possibly more but this was tested on these two). When we create a few threads that run SectionReport.LoadLayout instruction on a template that has an image in it sometimes the application will throw an exception:

  Exception form displayed for Value cannot be null.
  
  Parameter name: input
  
  Stack Trace:
  
  at System.IO.BinaryReader…ctor(Stream input, Encoding encoding, Boolean leaveOpen)
  
  at GrapeCity.ActiveReports.SectionReportModel.Picture.ReadXml(XmlNode controlNode)
  
  at GrapeCity.ActiveReports.SectionReportModel.ControlCollection.ReadXml(XmlNode sectionNode, SectionReport report)
  
  at GrapeCity.ActiveReports.SectionCollection.ReadXml(XmlNode sectionsNode)
  
  at GrapeCity.ActiveReports.SectionReport.#Qyb(XmlDocument layoutDoc, Boolean checkNames)
  
  at GrapeCity.ActiveReports.SectionReport.LoadLayout(XmlReader reader, ArrayList& errors)
  
  at GrapeCity.ActiveReports.SectionReport.LoadLayout(XmlReader reader)

  We attach the screenshot and a sample application that can be used to reproduce the problem. Please help us resolve this issue.
  
  PLEASE NOTE: The problem cannot be reproduced 100% of the time, if you cannot reproduce the issue change the ‘k’ value in MergeReport.cs, recompile and try again a few times. This problem happens around 10 - 20% of the times.

  Hello Adrian,

  Could you please use the following line of code and see if the issue resolve:

  
   public void createDocument()
          {
              SectionReport report = new SectionReport();      
              XmlTextReader xmlR = null;
  
              string path = System.IO.Path.GetDirectoryName(Assembly.GetEntryAssembly().Location) + @"\..\..\..\Resources\template.rpx";
  
              try
              {
                  xmlR = new System.Xml.XmlTextReader(path);
                  report.LoadLayout(xmlR);
                  xmlR.Close();
              }
              catch (Exception ex)
              {
                  throw ex;
              }
              lock (locker)
              {
                  t++;
              }
          }
  
  

  I have tested 7-8 times with above code and no issue occurs at my end.

  Thanks,
  
  Mohit

  Hello

  Thank you for your suggestion. Unfortunately the exception still occurs, I have tried both with try catch to make the code the same, and without to see full stack in console window. I attached the screenshots below.
  
  Again I had to try a few times before the exception occurred.
  
  This test was done on Active reports 11.3

  Thank you for your response.

  Can you tell me if this fix will be available in the next release of Active Reports (I assume 12.2) and if there is any release date for that version?
