• How to manage changes to reports in .NET?

  - by Craig Johnston

  If I need to offer the ability to create, view and print reports from a .NET app, I see that there are 2 options: use a reporting component such as Microsoft.Reporting.WinForms.ReportViewer or Crystal Reports which saves a .rpt or similar template file that can be modified as required without having to re-compile the app use System.Drawing.Printing for reporting and store report template data in a database, which keeps things simpler and avoids problems with bulky third party reporting components If I want to be able to modify a report template (which would include layout and data fields) without having to re-compile the app, would the first option above achieve this? If I wanted to be able to modify the template without re-compiling the app, how could this be achieved with the second option? How could you store data representing the templates in a database such that it could be modified without having to re-compile the app?

• Stored procs breaking overnight

  - by Chad

  We are running MS SQL 2005 and we have been experiencing a very peculiar problem the past few days. I have two procs, one that creates an hourly report of data. And another that calls it, puts its results in a temp table, and does some aggregations, and returns a summary. They work fine...until the next morning. The next morning, suddenly the calling report, complains about an invalid column name. The fix, is simply a recompile of the calling proc, and all works well again. How can this happen? It's happened three nights in a row since moving these procs into production.

  - by Mrouge

  I'm trying to parse an XML file I get from an external source but am having problems because there are unencoded XML entities in the text nodes. Essentially, I'm asking the same question as this, but for Perl instead of PHP. <report> <company>A & W</company> <company>Some Other Company with a < in Inc.</company> </report>

• Asp.Net Impersonation Fails On First Try But Succeeds on Second

  - by KevDog

  We are using RDLC's in a Asp.net web application. For reasons beyond our understanding, the first call to the database server fails with the following error: An error has occurred during report processing. Cannot open database "TryParkingIt2" requested by the login. The login failed. Login failed for user 'EXTRANET\OurServerNameHere$'. Run the report again, it works. Huh? Update Click the button the first time, it fails. Click the button again, it works. The account being impersonated is a domain account.

• Best method of including an abstract in a latex 'book'?

  - by olan

  Hello there. I've been looking for the answer to this question for a while now but can't seem to find it, so I'm hoping someone on here can help me. I'm writing up a thesis in Latex, and really like the \frontmatter, \mainmatter and \backmatter ability when using the "book" environment. However I need to add an abstract and the \begin{abstract} environment is undefined when creating a "book". If I change to a "report" however, I lose the functionality of the *matter terms. So what I really need to know is: is there a simple method of including an abstract in a "book" and have it formatted the same as it would be in a "report"? (i.e. centered vertically and horizontally with an 'abstract' heading) Thanks for any help! First post on stackoverflow after reading for months!

• rails rollback updates when task fails

  - by ash34

  Hi, I have the following "generate_report" method being called from a rake task, which gets a hash as an input, that contains the reported hours spent by each user on a task and outputs the data as a .csv report. desc "Task reporting" task :report, [:inp_dt] => [:environment] do |t, args| h = select_data(args.inp_dt) /* not shown here */ generate_report(h) end def generate_report(h) out_dir = File.dirname(__FILE__) + '/../../output' myfile = "#{out_dir}" + "/monthly_#{Date.today.strftime("%m%d%Y")}.csv" writer = CSV.open(myfile, 'w') h.each do |h,v| v.each do |key,val| writer << val end end writer.close end where h = {:BILL=>{:PROJA=>["CYR", "00876", "2", 24], :PROJB=>["EPR", "00876", "2", 16]}, :JANE=>{:PROJA=>["TRB", "049576", "2", 16]}} I would like to set/update a 'processed' flag for each reported transaction and only commit the update when the file is written correctly or rollback the updates when the task fails. How can I accomplish this. thanks, ash

• Possible Google Analytics Bug - Traffic Sources Total Visits not matching Total Visits in other repo

  - by SBAStats

  Hello, Has anyone else seen this issue? As of roughly 2 weeks ago, I get conflicting figures for the Total Visits metric between the Traffic Sources report and the other reports (e.g. Visitors, Dashboard). For example, for the week of 5/9/2010 through 5/15/2010, the Dashboard and Visitors reports both say 386 Visits. The Traffic Sources report says 157 Visits, and the 4 main source types (Search, Direct, Referral, Other) sum to 157 Visits, not 386. Any ideas? Is this a known bug, or could there be a configuration issue? Thanks.

• SSRS mysterious extra pages

  I have two reports that are setup with the same page dimensions- A4 portrait, with page margins of 1cm. When I run the reports seperately and print them they both come out as expected: fitting into the width constraint of the page. However, when I include one report as a subreport in the other and then run and print the "master" report I start to experience problems. Even though both reports appear I get extra blank pages appearing every other page in the output. I'm sure I'm missing a simple trick - probably with the page sizes of the two reports but I can't figure it out - any pointers? I don't mind changing the setup of the subreport as it will never be run as a seperate eport in the wild, I only included that step to prove that it did indeed fit within the page!

• How to nicely inform to the user that an unknown error has happened?

  - by Jaime Soriano

  There are several guidelines for error reporting, that are usually based on giving to the user useful information when he or she does something wrong, but to give this kind of information you need to be handling the error and know that it can happen. There are also tons of articles about designing 404 error pages. But, what can you do when it's a new, unhandled error provoked by a failure in the shoftware? Are there some guidelines about how to nicely report totally unexpected errors in a web site, as an unexpected error 500? What header message should be shown in that case? something like "Sorry, an unexpected error has ocurred" would be enough? What information should be given? Should it have mechanisms to help to report the failure to developers? Which ones?

• DynamicJasper(on Grails) Purposefully keep column or field blank(empty)

  - by petejoe

  Hi, I want to generate a pdf report, where a column(or cell/field) is left blank(empty) on purpose. This column actually does have a value but, I'm choosing not to display it. The column title still needs to be displayed. Example of where this could be useful: Blank(empty) column: A comments or notes column down one side of a report. Blank(empty) cell: A sudoku puzzle print-out. Much appreciated. DynamicJasper is Awesome! Thanks to the dj-team. Regards, Pete

• How can I test Windows Error Reporting?

  - by Deneb Meketa

  My company participates in Windows Error Reporting via Winqual. We'd like to add some additional data to our crash reports, using WERRegisterMemoryBlock. Obviously we'd like to make sure this is working before we ship our next version. How can we test it? Is there a way to locally preview precisely what is going to be sent? Does this realistically reproduce what we are going to be able to retrieve from Winqual? Alternatively, can we generate a real report from a developer machine, then retrieve the report from Winqual? How would we distinguish this test case from the rest of our Winqual data?

• No download dialog with FileResult

  - by majkinetor

  I am returning File result from action triggered by the form post event. I can't get download dialog. Instead, if I use: return File(Encoding.UTF8.GetBytes(reportPath), "text/plain", "Report.csv"); I get path to the file upon ajax execution in the target div. When I use return File(reportPath, "text/plain", "Report.csv"); I get content of the file in the target div. Any thoughts ? The action is declared as [HttpPost] public virtual ActionResult ExportFilter(Model model) { string outputFile = CreateReport(model); return File(....) }

• .rdlc reporting bound to Object Data Source in Three layer Application

  - by Saeedouv

  Hi, i have the following situation, i have a Reporting layer(stand alone) in asp.net application(NOT website, this means NO App_Code folder exists), and i want just to create Object Data Source to take an Object in a separate layer(lets say from Data Access Layer), and then to use that Object Data Source to create a report, i have spent my whole day working around that, tons of work around's and articles on the web, but does not mention what i really want to do, any answer is appriciated... just to make things more clear here, assume the following: i have a solution with the follwoing layers, UI Reporting(has NO Employees object) just a reference Business Logic Data Access Layer(Employees--GetEmployees(), all i need is as mentioned above, i want to create Object Data Source from Reporting layer, to take Employee object from DAL, and then use it's GetEmployees method to be added to report, i think its more clear now, since also Reporting layer has NO App_Code folder.

• .NET Free memory usage (how to prevent overallocation / release memory to the OS)

  - by Ronan Thibaudau

  I'm currently working on a website that makes large use of cached data to avoid roundtrips. At startup we get a "large" graph (hundreds of thouthands of different kinds of objects). Those objects are retrieved over WCF and deserialized (we use protocol buffers for serialization) I'm using redgate's memory profiler to debug memory issues (the memory didn't seem to fit with how much memory we should need "after" we're done initializing and end up with this report Now what we can gather from this report is that: 1) Most of the memory .NET allocated is free (it may have been rightfully allocated during deserialisation, but now that it's free, i'd like for it to return to the OS) 2) Memory is fragmented (which is bad, as everytime i refresh the cash i need to redo the memory hungry deserialisation process and this, in turn creates large object that may throw an OutOfMemoryException due to fragmentation) 3) I have no clue why the space is fragmented, because when i look at the large object heap, there are only 30 instances, 15 object[] are directly attached to the GC and totally unrelated to me, 1 is a char array also attached directly to the GC Heap, the remaining 15 are mine but are not the cause of this as i get the same report if i comment them out in code. So my question is, what can i do to go further with this? I'm not really sure what to look for in debugging / tools as it seems my memory is fragmented, but not by me, and huge amounts of free spaces are allocated by .net , which i can't release. Also please make sure you understand the question well before answering, i'm not looking for a way to free memory within .net (GC.Collect), but to free memory that is already free in .net , to the system as well as to defragment said memory. Note that a slow solution is fine, if it's possible to manually defragment the large heap i'd be all for it as i can call it at the end of RefreshCache and it's ok if it takes 1 or 2 second to run. Thanks for your help! A few notes i forgot: 1) The project is a .net 2.0 website, i get the same results running it in a .net 4 pool, idem if i run it in a .net 4 pool and convert it to .net 4 and recompile. 2) These are results of a release build, so debug build can not be the issue. 3) And this is probably quite important, i do not get these issues at all in the webdev server, only in IIS, in the webdev i get memory consumption rather close to my actual consumption (well more, but not 5-10X more!)

• Paging in SQL Server problems

  - by Manh Trinh

  I have searched for paging in SQL Server. I found most of the solution look like that What is the best way to paginate results in SQL Server But it don't meet my expectation. Here is my situation: I work on JasperReport, for that: to export the report I just need pass the any Select query into the template, it will auto generated out the report EX : I have a select query like this: Select * from table A I don't know any column names in table A. So I can't use Select ROW_NUMBER() Over (Order By columsName) And I also don't want it order by any columns. Anyone can help me do it? PS: In Oracle , it have rownum very helpful in this case. Select * from tableA where rownum > 100 and rownum <200 Paging with Oracle

• Ruby and Rails Async

  - by Edijs Petersons

  I need to perform long-running operation in ruby/rails asynchronously. Googling around one of the options I find is Sidekiq. class WeeklyReportWorker include Sidekiq::Worker def perform(user, product, year = Time.now.year, week = Date.today.cweek) report = WeeklyReport.build(user, product, year, week) report.save end end # call WeeklyReportWorker.perform_async('user', 'product') Everything works great! But there is a problem. If I keep calling this async method every few seconds, but the actual time heavy operation performs is one minute things won't work. Let me put it in example. 5.times { WeeklyReportWorker.perform_async('user', 'product') } Now my heavy operation will be performed 5 times. Optimally it should have performed only once or twice depending on whether execution of first operaton started before 5th async call was made. Do you have tips how to solve it?

• Locked visible cells Excel problem

  - by graham.reeds

  I have a problem with an Excel Template in Excel 2007. I need to remove a row from a summary report but the developer who created this report has somehow managed to set it so that only certain number of rows & columns are visible (in case you are interested it is A1:G30) - no headers, no grid, just blue nothingness. Deleting the offending line just peels back the white-ness. I want to change the resolution of the visible grid to A1:G29. I would ask on google but I haven't the foggiest what the tool would be called to do this (if I did I probably wouldn't be asking). Giving generic terms gives very generic results. I've been through every ribbon and came up blank. Help me out my misery - please!

• How to execute ant using java and captured the output?

  - by Iso

  Hi, I have an ant build file that contains JUnit test suite that I would like to execute. Currently I just right click and run the build file from Eclipse. I want to write a java code that can execute the ant build file automatically. So I just run the code and ant will be executed. Second is I want to capture the test result. Currently the result is based on JUnit HTML report. I want to make my own simple test report. I read there is JUnitResultFormatter but I can't find the instructional step by step how to use it. Can anyone point me the reference? Thanks in advance.

• In LaTeX, is there a way to get long lines along the margins?

  - by Christian Jonassen

  I'm working on a report, and some elements are outside the margins (but some are just barely outside the margins). I was wondering: Is there a way to make two vertical lines, one on each side, along the margins so that one can easily see if it goes outside them? (Googling it, I only found information about margin notes.) A figure is below: |report text goes here| |more text goes also h|ere |and so on and so fort|h It would certainly make correcting these kinds of mistakes very trivial. :) Feel free to post answers that would solve/show this problem in a more "LaTeX-correct" way, if that makes any sense at all.

• Errors with large data sources

  - by The Sheek Geek

  I'm doing some benchmarking on large data sources and binding/exporting data for reporting. I started with using a data set, filling it with 100000 rows and then attempting to open a crystal report with the retrieved data. I noticed that the data set filled just fine (took about 779 milliseconds) however, when attempting to export the data to the report or even bind to a gridview the application would fail with an OutOfMemoryException. Does anyone experienced this before or have an idea of how to get around it? It is very possible that clients will run reports for years worth of data and 100000 rows are not inconceivable. The application and the benchmark code are written in C# using ORACLE and SQL Server databases. I still have some data sources to test, but would like to know how to get around this just in case I don't find a better solution.

• SSRS doesn't honor the CanGrow Property when Exporting to Excel

  - by user181857

  I have a Table in an SSRS report. one of the Table Cells contains the Descriptions of Parts in an order. these descriptions could vary in length and for that reson i have set the "CanGrow" Property to True. when i try to export the report to Excel im expecting that if the text length would exceed the width of the Cell then the height of the cell would grow and the whole text would be shown. Unfortunately the SSRS Excel Generator keeps the height as is and so only the part of the text which fits the width of the cell would be shown. i would appreciate any help or input to solve this problem. Thanks

• SSRS Issue: Rounding to nearest .25

  - by D.R.

  I have an SSRS (2008) report that takes in a raw transactions, then groups and totals them. At the "Total" level, I would like to round the final numbers to the nearest .25, however I cannot find a method to do this. According to what I've read, the Round() function in SSRS only rounds to integers. I have found a couple ways to do it in SQL, but the problem is, I want to do all the calculations with the REAL numbers and just round the result so that I don't introduce a significant amount of error from the real numbers. Here's the best SQL solution I could find: dec(round(number * 4, 0)/4,11,2) as Nearest_Qtr Anyone know how I could do the equivalent in the actual SSRS report? Thanks in advance for the help!

• Screen orientation change forces data re-entry

  - by Timbermar

  I'm developing a simple app, only a handful of activities and nothing to complicated. The issue I'm having is that in a few of my activities I have EditText widgets, and when the screen is rotated, these widgets loose their values. They still visually, that is, on the handset screen, report their values from before the rotation, but to the code report their default values. An example, I have an activity with an EditText, I enter a number, 15, the calculator starts calculating, displays a result. If at this point I rotate to a different orientation, as expected the activity dies, reloads, shows the new orientation, my value of 15 is still in the EditText, however the calculator (the code) calculates as if it was 0, which is the initial value. I have not tried changing the initial value to see if it is really pulling from the default value, or just setting itself to 0 when I cast it as an int. If I didn't explain this well enough, let me know, I can add source code if I need to. Thanks.
