  Have a complex report that works fine in AR12.2. Did upgrade to AR13.1 (latest) and did run same report. id did notice that A lot of memory (about 2Gb) where allocated and get the Out of memory error in the .Run cmd.
  
  I use the %temp% folder as cachetodisk path and can see that tmp files are created but byte size is “0” for every file…

  When i run same report in AR12.2 the tmp files are growing as the report progress. and memory consuming is about 400Mb vs 2Gb

  Hello mohitg !
  
  The link to the AR13 hotfix made my report come up and it worked 1st time in debug x86, the second time i run it i got out of memory…
  
  The memory consumption peaked at 1Gb ram but dropped down and peaked up 1Gb a couple of times.

  Its difficult to send you code samples for this but i provided the files in attached file.
  
  We have a global SectionReport document where we Add pages for each report that is created.
  
  The main loop for the report that we get the error in is like this:

  pdoc6_A4p = new Rpt6.Rpt06_A4p();
  
  pdoc6_A4p.Document.Name = Properties.Resources.IDS_RappName_6;
  
  pdoc6_A4p.strXmlFile = strXmlFile;
  
  pdoc6_A4p.iStartPage = iStartPage;
  
  pdoc6_A4p.bMultiRpt = bMultiRpt;

  pdoc6_A4p.Document.CacheToDisk = true;
  
  pdoc6_A4p.Document.CacheToDiskLocation = System.IO.Path.GetTempPath();

  try
  
  {
  
  pdoc6_A4p.Run(true); <— Here it stops with exception after a while …
  
  }
  
  catch (Exception err)
  
  {
  
  MessageBox.Show(err.Message, “Rpt6”, MessageBoxButtons.OK,
  
  MessageBoxIcon.Error);

     pdoc6_A4p.Dispose();
     pdoc6_A4p = null;
    throw;
  

  }

  pdoc6_A4p.Document.Bookmarks.Clear();
  
  Bookmark bk = new Bookmark();
  
  bk.Label = Properties.Resources.IDS_RappName_6;
  
  bk.PageNumber = iStartPage;
  
  pDoc.Document.Bookmarks.Add(bk);

  for (int i = 0; i < pdoc6_A4p.Document.Pages.Count; i++)
  
  {
  
  pDoc.Document.Pages.Add(pdoc6_A4p.Document.Pages[i]);
  
  }
  
  …

  the build i was running in AR12: 12.2.13986.0

  Hello,

  What I understood from this, you got an exception on executing the report second time in the same application instance. You are facing the same problem with AR12 and AR13. If my understanding is correct then please dispose the report object before executing it the second time. Using the following line of code to dispose the object:

  rpt.Document.Dispose();
  rpt.Dispose();
  rpt=null;
  

  Please explain if my understanding is incorrect. Also If the problem occurs while executing the application second time, then please after using the above code in FormClosing event.

  Hope it helps.

  Thanks.

  Hello,

  In AR12 i do not get any error, and can execute the report several times without closing the application.

  And if i add “pdoc6_A4p.Document.Dispose();” i get error in the main report document “pDoc” because we “Add” all pages from “pdoc6_A4p” to the “pDoc” object in this example.

  The “pDoc” is loaded into viewer later on when all reports are generated.

  Hello,

  Is there any reason that you do not assign the static resources like image in the ReportStart event handler.

  Thanks,

  The only image i assign dynamic in report is the Company logotype in the ReportStart event. ?
  
  All other images is assigned in subreports detail/group section. Can i save memory consumption if i add the ReportStart event for each of the subreports and assign the images in the event instead ?

  Hello Jorgan,

  If the image is the same throughout the report then I will recommend you to set in the ReportStart event. It will save memory consumption in the report.

  However, if the image is different in every detail section then I will recommend you to set in the Format event of Detail section. Also, we are working on the hotfix for you.

  Hope it clarifies.

  Thanks.
