vb.net - Tips for debugging likely Crystal Reports hang in ASP.NET -


Trying to keep this small: Our shipping personnel sent on using a windows mobile-enabled barcode scanner Order the customer to scan the serial number of the item. This data is presented through the asmx web service and a report is automatically showing customer information to a client printer and shows details of the item to be sent. It all happens in an intranet environment.

Recently, I was using the Microsoft Report Engine which was created in the Viewer Studio (.rlcc file) and code generated to generate the report and printed without user intervention.

Recently, I took part in some reports in MS reports against formatting limitations and instead applied reports in Crystal Reports (10.5.3700). This code works fine, but after running for a day or more for a few hours, the ASP.NET Worker process is hanging (not sure that it is a proper term). Without throwing an exception, the generating / printing process always keeps running. Recycling the apple, for a while, everything works again.

The report is using the "push" mode, where the report is given a dataset typed instead of reaching the database itself. To extract the CR ReportDocument.PrintToPrinter () method from the equation, I have considered exporting PDFs or similar reports, and then the result is printing the file independently. But I have yet to do this Great way is not found.

To search for the problem, I have read all the complaints about the buggy bug, but I hope there is a bug in my code which is for cleaning after the report is printed. Import CrystalDecisions.CrystalReports.Engine Import CrystalDecisions.ReportAppServer Import CrystalDecisions.Shared Public Class CrystalReport Personal _report ReportDocument Public Sub-New (ByVal Path as String) _report = New ReportDocument (as) _report.Load (path) end subsystem sub-set data source (data dataset as data dataset) _report.SetDataSource (dataset) termination sub-public sub addParameter (string as object, byVal name as ByVal value) dim crParameterFieldDefinitions ParameterFieldDefinitions = _report.DataDefinition.ParameterFields dim crParameter1 Dimam ParameterFieldDefi Nition = crParameterFieldDefinitions.Item (name) Dim parameterValue CrystalDecisions.Shared.ParameterDiscreteValue = New CrystalDecisions.Shared.ParameterDiscreteValue () P ArameterValue.Value = Value crParameter1.CurrentValues.Add (parameterValue) crParameter1.ApplyCurrentValues ​​(crParameter1.CurrentValues ) And sub-public all print end (by-by-printer path) _report.PrintOptions.PrinterName = PrinterPath _report.PrintToPrinter (1, true, 0, 0) closed () End sub personal sub-lock () _report.Close () _report.Dispose () _report = Nothing else from the other end class sub

Any ideas for debugging this further? I've never had to resort to real Windows debugging (WinDbg, Process Explorer, etc.), so any recommendation which would be great to try first on debugging equipment.

Thank you.

You are trying to get your report object on off () ing and settlement () Page_Unload trying the status of your ASP Can the .NET page talk about a problem on Microsoft ASP.NET platforms where the report reaches the maximum number of processing jobs, but I think that may be related to this issue.

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
