• Part 8: How to name EBS Customizations

  - by volker.eckardt(at)oracle.com

  You might wonder why I am discussing this here. The reason is simple: nearly every project has a bit different naming conventions, which makes a the life always a bit complicated (for developers, but also setup responsible, and also for consultants).  Although we always create a document to describe the technical object naming conventions, I have rarely seen a dedicated document  with functional naming conventions. To be precisely, from my stand point, there should always be one global naming definition for an implementation! Let me discuss some related questions: What is the best convention for the customization reference? How to name database objects (tables, packages etc.)? How to name functional objects like Value Sets, Concurrent Programs, etc. How to separate customizations from standard objects best? What is the best convention for the customization reference? The customization reference is the key you use to reference your customization from other lists, from the project plan etc. Usually it is something like XXHU_CONV_22 (HU=customer abbreviation, CONV=Conversion object #22) or XXFA_DEPRN_RPT_02 (FA=Fixed Assets, DEPRN=Short object group, here depreciation, RPT=Report, 02=2nd report in this area) As this is just a reference (not an object name yet), I would prefer the second option. XX=Customization, FA=Main EBS Module linked (you may have sometimes more, but FA is the main) DEPRN_RPT=Short name to specify the customization 02=a unique number Important here is that the HU isn’t used, because XX is enough to mark a custom object, and the 3rd+4th char can be used by the EBS module short name. How to name database objects (tables, packages etc.)? I was leading different developer teams, and I know that one common way is it to take the Customization reference and add more chars behind to classify the object (like _V for view and _T1 for triggers etc.). The only concern I have with this approach is the reusability. If you name your view XXFA_DEPRN_RPT_02_V, no one will by choice reuse this nice view, as it seams to be specific for this CEMLI. My suggestion is rather to name the view XXFA_DEPRN_PERIODS_V and allow herewith reusability for other CEMLIs (although the view will be deployed primarily with CEMLI package XXFA_DEPRN_RPT_02). (check also one of the following Blogs where I will talk about deployment.) How to name Value Sets, Concurrent Programs, etc. For Value Sets I would go with the same convention as for database objects, starting with XX<Module> …. For Concurrent Programs the situation is a bit different. This “object” is seen and used by a lot of users, and they will search for. In many projects it is common to start again with the company short name, or with XX. My proposal would differ. If you have created your own report and you name it “XX: Invoice Report”, the user has to remember that this report does not start with “I”, it starts with X. Would you like typing an X if you are looking for an Invoice report? No, you wouldn’t! So my advise would be to name it:   “Invoice Report (XXAP)”. Still we know it is custom (because of the XXAP), but the end user will type the key “i” to get it (and will see similar reports starting also with “i”). I hope that the general schema behind has now become obvious. How to separate customizations from standard objects best? I would not have this section here if the naming would not play an important role. Unfortunately, we can not always link a custom application to our own object, therefore the naming is really important. In the file system structure we use our $XXyy_TOP, in JAVA_TOP it is perhaps also “xx” in front. But in the database itself? Although there are different concepts in place, still many implementations are using the standard “apps” approach, means custom objects are stored in the apps schema (which should not cause any trouble). Final advise: review the naming conventions regularly, once a month. You may have to add more! And, publish them! To summarize: Technical and functional customized objects should always follow a naming convention. This naming convention should be project wide, and only one place shall be used to maintain (like in a Wiki). If the name is for the end user, rather put a customization identifier at the end; if it is an internal name, start with XX…

• Google Analytics recording event based on <a> title attribute

  - by rlsaj

  I am declaring: var title = (typeof(el.attr('title')) != 'undefined' ) ? el.attr('title') :""; and then have the following: else if (title.match(/^"Matching Content"\:/i)) { elEv.category = "Matching Content Click"; elEv.action = "click-Matching-Content"; elEv.label = href.replace(/^https?\:\/\//i, ''); elEv.non_i = true; elEv.loc = href; } However, using Google Analytics debugger this is not being recorded. Any suggestions? The complete function is: if (typeof jQuery != 'undefined') { jQuery(document).ready(function gLinkTracking($) { var filetypes = /\.(avi|csv|dat|dmg|doc.*|exe|flv|gif|jpg|mov|mp3|mp4|msi|pdf|png|ppt.*|rar|swf|txt|wav|wma|wmv|xls.*|zip)$/i; var baseHref = ''; if (jQuery('base').attr('href') != undefined) baseHref = jQuery('base').attr('href'); jQuery('a').on('click', function (event) { var el = jQuery(this); var track = true; var href = (typeof(el.attr('href')) != 'undefined' ) ? el.attr('href') :""; var title = (typeof(el.attr('title')) != 'undefined' ) ? el.attr('title') :""; var isThisDomain = href.match(document.domain.split('.').reverse()[1] + '.' + document.domain.split('.').reverse()[0]); if (!href.match(/^javascript:/i)) { var elEv = []; elEv.value=0, elEv.non_i=false; if (href.match(/^mailto\:/i)) { elEv.category = "Email link"; elEv.action = "click-email"; elEv.label = href.replace(/^mailto\:/i, ''); elEv.loc = href; } else if (title.match(/^"Matching Content"\:/i)) { elEv.category = "Matching Content Click"; elEv.action = "click-Matching-Content"; elEv.label = href.replace(/^https?\:\/\//i, ''); elEv.non_i = true; elEv.loc = href; } else if (href.match(filetypes)) { var extension = (/[.]/.exec(href)) ? /[^.]+$/.exec(href) : undefined; elEv.category = "File Downloaded"; elEv.action = "click-" + extension[0]; elEv.label = href.replace(/ /g,"-"); elEv.loc = baseHref + href; } else if (href.match(/^https?\:/i) && !isThisDomain) { elEv.category = "External link"; elEv.action = "click-external"; elEv.label = href.replace(/^https?\:\/\//i, ''); elEv.non_i = true; elEv.loc = href; } else if (href.match(/^tel\:/i)) { elEv.category = "Telephone link"; elEv.action = "click-telephone"; elEv.label = href.replace(/^tel\:/i, ''); elEv.loc = href; } else track = false; if (track) { _gaq.push(['_trackEvent', elEv.category.toLowerCase(), elEv.action.toLowerCase(), elEv.label.toLowerCase(), elEv.value, elEv.non_i]); if ( el.attr('target') == undefined || el.attr('target').toLowerCase() != '_blank') { setTimeout(function() { location.href = elEv.loc; }, 400); return false; } } } }); }); }

• Clouds, Clouds, Clouds Everywhere, Not a Drop of Rain!

  - by sxkumar

  At the recently concluded Oracle OpenWorld 2012, the center of discussion was clearly Cloud. Over the five action packed days, I got to meet a large number of customers and most of them had serious interest in all things cloud.  Public Cloud - particularly the Oracle Cloud - clearly got a lot of attention and interest. I think the use cases and the value proposition for public cloud is pretty straight forward. However, when it comes to private cloud, there were some interesting revelations.  Well, I shouldn’t really call them revelations since they are pretty consistent with what I have heard from customers at other conferences as well as during 1:1 interactions. While the interest in enterprise private cloud remains to be very high, only a handful of enterprises have truly embarked on a journey to create what the purists would call true private cloud - with capabilities such as self-service and chargeback/show back. For a large majority, today's reality is simply consolidation and virtualization - and they are quite far off from creating an agile, self-service and transparent IT infrastructure which is what the enterprise cloud is all about.  Even a handful of those who have actually implemented a close-to-real enterprise private cloud have taken an infrastructure centric approach and are seeing only limited business upside. Quite a few were frank enough to admit that chargeback and self-service isn’t something that they see an immediate need for.  This is in quite contrast to the picture being painted by all those surveys out there that show a large number of enterprises having already implemented an enterprise private cloud.  On the face of it, this seems quite contrary to the observations outlined above. So what exactly is the reality? Well, the reality is that there is undoubtedly a huge amount of interest among enterprises about transforming their legacy IT environment - which is often seen as too rigid, too fragmented, and ultimately too expensive - to something more agile, transparent and business-focused. At the same time however, there is a great deal of confusion among CIOs and architects about how to get there. This isn't very surprising given all the buzz and hype surrounding cloud computing. Every IT vendor claims to have the most unique solution and there isn't a single IT product out there that does not have a cloud angle to it. Add to this the chatter on the blogosphere, it will get even a sane mind spinning.  Consequently, most  enterprises are still struggling to fully understand the concept and value of enterprise private cloud.  Even among those who have chosen to move forward relatively early, quite a few have made their decisions more based on vendor influence/preferences rather than what their businesses actually need.  Clearly, there is a disconnect between the promise of the enterprise private cloud and the current adoption trends.  So what is the way forward?  I certainly do not claim to have all the answers. But here is a perspective that many cloud practitioners have found useful and thus worth sharing. To take a step back, the fundamental premise of the enterprise private cloud is IT transformation. It is the quest to create a more agile, transparent and efficient IT infrastructure that is driven more by business needs rather than constrained by operational and procedural inefficiencies. It is the new way of delivering and consuming IT services - where the IT organizations operate more like enablers of  strategic services rather than just being the gatekeepers of IT resources. In an enterprise private cloud environment, IT organizations are expected to empower the end users via self-service access/control and provide the business stakeholders a transparent view of how the resources are being used, what’s the cost of delivering a given service, how well are the customers being served, etc.  But the most important thing to note here is the enterprise private cloud is not just an IT project, rather it is a business initiative to create an IT setup that is more aligned with the needs of today's dynamic and highly competitive business environment. Surprised? You shouldn’t be. Just remember how the business users have been at the forefront of public cloud adoption within enterprises and private cloud is no exception.   Such a broad-based transformation makes cloud more than a technology initiative. It requires people (organizational) and process changes as well, and these changes are as critical as is the choice of right tools and technology. In my next blog,  I will share how essential it is for enterprise cloud technology to go hand-in hand with process re-engineering and organization changes to unlock true value of  enterprise cloud. I am sharing a short video from my session "Managing your private Cloud" at Oracle OpenWorld 2012. More videos from this session will be posted at the recently introduced Zero to Cloud resource page. Many other experts of Oracle enterprise private cloud solution will join me on this blog "Zero to Cloud"  and share best practices , deployment tips and information on how to plan, build, deploy, monitor, manage , meter and optimize the enterprise private cloud. We look forward to your feedback, suggestions and having an engaging conversion with you on this blog.

• Why is this beat detection code failing to register some beats properly?

  - by Quincy

  I made this SoundAnalyzer class to detect beats in songs: class SoundAnalyzer { public SoundBuffer soundData; public Sound sound; public List<double> beatMarkers = new List<double>(); public SoundAnalyzer(string path) { soundData = new SoundBuffer(path); sound = new Sound(soundData); } // C = threshold, N = size of history buffer / 1024 B = bands public void PlaceBeatMarkers(float C, int N, int B) { List<double>[] instantEnergyList = new List<double>[B]; GetEnergyList(B, ref instantEnergyList); for (int i = 0; i < B; i++) { PlaceMarkers(instantEnergyList[i], N, C); } beatMarkers.Sort(); } private short[] getRange(int begin, int end, short[] array) { short[] result = new short[end - begin]; for (int i = 0; i < end - begin; i++) { result[i] = array[begin + i]; } return result; } // get a array of with a list of energy for each band private void GetEnergyList(int B, ref List<double>[] instantEnergyList) { for (int i = 0; i < B; i++) { instantEnergyList[i] = new List<double>(); } short[] samples = soundData.Samples; float timePerSample = 1 / (float)soundData.SampleRate; int sampleIndex = 0; int nextSamples = 1024; int samplesPerBand = nextSamples / B; // for the whole song while (sampleIndex + nextSamples < samples.Length) { complex[] FFT = FastFourier.Calculate(getRange(sampleIndex, nextSamples + sampleIndex, samples)); // foreach band for (int i = 0; i < B; i++) { double energy = 0; for (int j = 0; j < samplesPerBand; j++) energy += FFT[i * samplesPerBand + j].GetMagnitude(); energy /= samplesPerBand; instantEnergyList[i].Add(energy); } if (sampleIndex + nextSamples >= samples.Length) nextSamples = samples.Length - sampleIndex - 1; sampleIndex += nextSamples; samplesPerBand = nextSamples / B; } } // place the actual markers private void PlaceMarkers(List<double> instantEnergyList, int N, float C) { double timePerSample = 1 / (double)soundData.SampleRate; int index = N; int numInBuffer = index; double historyBuffer = 0; //Fill the history buffer with n * instant energy for (int i = 0; i < index; i++) { historyBuffer += instantEnergyList[i]; } // If instantEnergy / samples in buffer < instantEnergy for the next sample then add beatmarker. while (index + 1 < instantEnergyList.Count) { if(instantEnergyList[index + 1] > (historyBuffer / numInBuffer) * C) beatMarkers.Add((index + 1) * 1024 * timePerSample); historyBuffer -= instantEnergyList[index - numInBuffer]; historyBuffer += instantEnergyList[index + 1]; index++; } } } For some reason it's only detecting beats from 637 sec to around 641 sec, and I have no idea why. I know the beats are being inserted from multiple bands since I am finding duplicates, and it seems that it's assigning a beat to each instant energy value in between those values. It's modeled after this: http://www.flipcode.com/misc/BeatDetectionAlgorithms.pdf So why won't the beats register properly?

• C++ strongly typed typedef

  - by Kian

  I've been trying to think of a way of declaring strongly typed typedefs, to catch a certain class of bugs in the compilation stage. It's often the case that I'll typedef an int into several types of ids, or a vector to position or velocity: typedef int EntityID; typedef int ModelID; typedef Vector3 Position; typedef Vector3 Velocity; This can make the intent of code more clear, but after a long night of coding one might make silly mistakes like comparing different kinds of ids, or adding a position to a velocity perhaps. EntityID eID; ModelID mID; if ( eID == mID ) // <- Compiler sees nothing wrong { /*bug*/ } Position p; Velocity v; Position newP = p + v; // bug, meant p + v*s but compiler sees nothing wrong Unfortunately, suggestions I've found for strongly typed typedefs include using boost, which at least for me isn't a possibility (I do have c++11 at least). So after a bit of thinking, I came upon this idea, and wanted to run it by someone. First, you declare the base type as a template. The template parameter isn't used for anything in the definition, however: template < typename T > class IDType { unsigned int m_id; public: IDType( unsigned int const& i_id ): m_id {i_id} {}; friend bool operator==<T>( IDType<T> const& i_lhs, IDType<T> const& i_rhs ); }; Friend functions actually need to be forward declared before the class definition, which requires a forward declaration of the template class. We then define all the members for the base type, just remembering that it's a template class. Finally, when we want to use it, we typedef it as: class EntityT; typedef IDType<EntityT> EntityID; class ModelT; typedef IDType<ModelT> ModelID; The types are now entirely separate. Functions that take an EntityID will throw a compiler error if you try to feed them a ModelID instead, for example. Aside from having to declare the base types as templates, with the issues that entails, it's also fairly compact. I was hoping anyone had comments or critiques about this idea? One issue that came to mind while writing this, in the case of positions and velocities for example, would be that I can't convert between types as freely as before. Where before multiplying a vector by a scalar would give another vector, so I could do: typedef float Time; typedef Vector3 Position; typedef Vector3 Velocity; Time t = 1.0f; Position p = { 0.0f }; Velocity v = { 1.0f, 0.0f, 0.0f }; Position newP = p + v*t; With my strongly typed typedef I'd have to tell the compiler that multypling a Velocity by a Time results in a Position. class TimeT; typedef Float<TimeT> Time; class PositionT; typedef Vector3<PositionT> Position; class VelocityT; typedef Vector3<VelocityT> Velocity; Time t = 1.0f; Position p = { 0.0f }; Velocity v = { 1.0f, 0.0f, 0.0f }; Position newP = p + v*t; // Compiler error To solve this, I think I'd have to specialize every conversion explicitly, which can be kind of a bother. On the other hand, this limitation can help prevent other kinds of errors (say, multiplying a Velocity by a Distance, perhaps, which wouldn't make sense in this domain). So I'm torn, and wondering if people have any opinions on my original issue, or my approach to solving it.

• IsNumeric() Broken? Only up to a point.

  - by Phil Factor

  In SQL Server, probably the best-known 'broken' function is poor ISNUMERIC() . The documentation says 'ISNUMERIC returns 1 when the input expression evaluates to a valid numeric data type; otherwise it returns 0. ISNUMERIC returns 1 for some characters that are not numbers, such as plus (+), minus (-), and valid currency symbols such as the dollar sign ($).'Although it will take numeric data types (No, I don't understand why either), its main use is supposed to be to test strings to make sure that you can convert them to whatever numeric datatype you are using (int, numeric, bigint, money, smallint, smallmoney, tinyint, float, decimal, or real). It wouldn't actually be of much use anyway, since each datatype has different rules. You actually need a RegEx to do a reasonably safe check. The other snag is that the IsNumeric() function  is a bit broken. SELECT ISNUMERIC(',')This cheerfully returns 1, since it believes that a comma is a currency symbol (not a thousands-separator) and you meant to say 0, in this strange currency.  However, SELECT ISNUMERIC(N'£')isn't recognized as currency.  '+' and  '-' is seen to be numeric, which is stretching it a bit. You'll see that what it allows isn't really broken except that it doesn't recognize Unicode currency symbols: It just tells you that one numeric type is likely to accept the string if you do an explicit conversion to it using the string. Both these work fine, so poor IsNumeric has to follow suit. SELECT  CAST('0E0' AS FLOAT)SELECT  CAST (',' AS MONEY) but it is harder to predict which data type will accept a '+' sign. SELECT  CAST ('+' AS money) --0.00SELECT  CAST ('+' AS INT)   --0SELECT  CAST ('+' AS numeric)/* Msg 8115, Level 16, State 6, Line 4 Arithmetic overflow error converting varchar to data type numeric.*/SELECT  CAST ('+' AS FLOAT)/*Msg 8114, Level 16, State 5, Line 5Error converting data type varchar to float.*/> So we can begin to say that the maybe IsNumeric isn't really broken, but is answering a silly question 'Is there some numeric datatype to which i can convert this string? Almost, but not quite. The bug is that it doesn't understand Unicode currency characters such as the euro or franc which are actually valid when used in the CAST function. (perhaps they're delaying fixing the euro bug just in case it isn't necessary).SELECT ISNUMERIC (N'?23.67') --0SELECT  CAST (N'?23.67' AS money) --23.67SELECT ISNUMERIC (N'£100.20') --1SELECT  CAST (N'£100.20' AS money) --100.20 Also the CAST function itself is quirky in that it cannot convert perfectly reasonable string-representations of integers into integersSELECT ISNUMERIC('200,000')       --1SELECT  CAST ('200,000' AS INT)   --0/*Msg 245, Level 16, State 1, Line 2Conversion failed when converting the varchar value '200,000' to data type int.*/  A more sensible question is 'Is this an integer or decimal number'. This cuts out a lot of the apparent quirkiness. We do this by the '+E0' trick. If we want to include floats in the check, we'll need to make it a bit more complicated. Here is a small test-rig. SELECT  PossibleNumber,         ISNUMERIC(CAST(PossibleNumber AS NVARCHAR(20)) + 'E+00') AS Hack,        ISNUMERIC (PossibleNumber + CASE WHEN PossibleNumber LIKE '%E%'                                          THEN '' ELSE 'E+00' END) AS Hackier,        ISNUMERIC(PossibleNumber) AS RawIsNumericFROM    (SELECT CAST(',' AS NVARCHAR(10)) AS PossibleNumber          UNION SELECT '£' UNION SELECT '.'         UNION SELECT '56' UNION SELECT '456.67890'         UNION SELECT '0E0' UNION SELECT '-'         UNION SELECT '-' UNION SELECT '.'         UNION  SELECT N'?' UNION SELECT N'¢'        UNION  SELECT N'?' UNION SELECT N'?34.56'         UNION SELECT '-345' UNION SELECT '3.332228E+09') AS examples Which gives the result ... PossibleNumber Hack Hackier RawIsNumeric-------------- ----------- ----------- ------------? 0 0 0- 0 0 1, 0 0 1. 0 0 1¢ 0 0 1£ 0 0 1? 0 0 0?34.56 0 0 00E0 0 1 13.332228E+09 0 1 1-345 1 1 1456.67890 1 1 156 1 1 1 I suspect that this is as far as you'll get before you abandon IsNumeric in favour of a regex. You can only get part of the way with the LIKE wildcards, because you cannot specify quantifiers. You'll need full-blown Regex strings like these ..[-+]?\b[0-9]+(\.[0-9]+)?\b #INT or REAL[-+]?\b[0-9]{1,3}\b #TINYINT[-+]?\b[0-9]{1,5}\b #SMALLINT.. but you'll get even these to fail to catch numbers out of range.So is IsNumeric() an out and out rogue function? Not really, I'd say, but then it would need a damned good lawyer.

• sp_send_dbmail attach files stored as varbinary in database

  - by Mindstorm Interactive

  I have a two part question relating to sending query results as attachments using sp_send_dbmail. Problem 1: Only basic .txt files will open. Any other format like .pdf or .jpg are corrupted. Problem 2: When attempting to send multiple attachments, I receive one file with all file names glued together. I'm running SQL Server 2005 and I have a table storing uploaded documents: CREATE TABLE [dbo].[EmailAttachment]( [EmailAttachmentID] [int] IDENTITY(1,1) NOT NULL, [MassEmailID] [int] NULL, -- foreign key [FileData] [varbinary](max) NOT NULL, [FileName] [varchar](100) NOT NULL, [MimeType] [varchar](100) NOT NULL I also have a MassEmail table with standard email stuff. Here is the SQL Send Mail script. For brevity, I've excluded declare statements. while ( (select count(MassEmailID) from MassEmail where status = 20 )>0) begin select @MassEmailID = Min(MassEmailID) from MassEmail where status = 20 select @Subject = [Subject] from MassEmail where MassEmailID = @MassEmailID select @Body = Body from MassEmail where MassEmailID = @MassEmailID set @query = 'set nocount on; select cast(FileData as varchar(max)) from Mydatabase.dbo.EmailAttachment where MassEmailID = '+ CAST(@MassEmailID as varchar(100)) select @filename = '' select @filename = COALESCE(@filename+ ',', '') +FileName from EmailAttachment where MassEmailID = @MassEmailID exec msdb.dbo.sp_send_dbmail @profile_name = 'MASS_EMAIL', @recipients = '[email protected]', @subject = @Subject, @body =@Body, @body_format ='HTML', @query = @query, @query_attachment_filename = @filename, @attach_query_result_as_file = 1, @query_result_separator = '; ', @query_no_truncate = 1, @query_result_header = 0; update MassEmailset status= 30,SendDate = GetDate() where MassEmailID = @MassEmailID end I am able to successfully read files from the database so I know the binary data is not corrupted. .txt files only read when I cast FilaData to varchar. But clearly original headers are lost. It's also worth noting that attachment file sizes are different than the original files. That is most likely due to improper encoding as well. So I'm hoping there's a way to create file headers using the stored mimetype, or some way to include file headers in the binary data? I'm also not confident in the values of the last few parameters, and I know coalesce is not quite right, because it prepends the first file name with a comma. But good documentation is nearly impossible to find. Please help!

• KnpLabs / DoctrineBehaviors Translatable - currentLocale = null

  - by Ruben

  Using the trait \Knp\DoctrineBehaviors\Model\Translatable\Translation inside an Entity, I see that the property currentLocale is never setted , so we always obtain the default locale ('en') in all the calls to $this->translate(). If I change this getDefaultLocale, all the translations are made correctly, so I think that is no problem with the fallback. I tried debug the currentLocaleCallable. I see that if I put a "var_dump ($this-container-get('request'));" in the contructor of currentLocaleCallable, the request have a locale to null. And outside the request has the correct locale.It seems that container is not in the scope: request , i don't know how can I get it to work I post an issue in github https://github.com/KnpLabs/DoctrineBehaviors/issues/71 EDITED This service is defined in vendor/knplabs/doctrine-behaviors/config/orm-services.yml and is: knp.doctrine_behaviors.reflection.class_analyzer: class: "%knp.doctrine_behaviors.reflection.class_analyzer.class%" public: false knp.doctrine_behaviors.translatable_listener: class: "%knp.doctrine_behaviors.translatable_listener.class%" public: false arguments: - "@knp.doctrine_behaviors.reflection.class_analyzer" - "%knp.doctrine_behaviors.reflection.is_recursive%" - "@knp.doctrine_behaviors.translatable_listener.current_locale_callable" tags: - { name: doctrine.event_subscriber } knp.doctrine_behaviors.translatable_listener.current_locale_callable: class: "%knp.doctrine_behaviors.translatable_listener.current_locale_callable.class%" arguments: - "@service_container" # lazy request resolution public: false EDIT 2: My composer.json "php": ">=5.3.3", "symfony/symfony": "2.3.*", "doctrine/orm": ">=2.2.3,<2.4-dev", "doctrine/doctrine-bundle": "1.2.*", "twig/extensions": "1.0.*", "symfony/assetic-bundle": "2.3.*", "symfony/swiftmailer-bundle": "2.3.*", "symfony/monolog-bundle": "2.3.*", "sensio/distribution-bundle": "2.3.*", "sensio/framework-extra-bundle": "2.3.*", "sensio/generator-bundle": "2.3.*", "incenteev/composer-parameter-handler": "~2.0", "friendsofsymfony/user-bundle": "1.3.*", "avalanche123/imagine-bundle": "v2.1", "raulfraile/ladybug-bundle": "~1.0", "genemu/form-bundle": "2.2.*", "friendsofsymfony/rest-bundle": "0.12.0", "stof/doctrine-extensions-bundle": "dev-master", "sonata-project/admin-bundle": "dev-master", "a2lix/translation-form-bundle": "1.*@dev", "sonata-project/user-bundle": "dev-master", "psliwa/pdf-bundle": "dev-master", "jms/serializer-bundle": "dev-master", "jms/di-extra-bundle": "dev-master", "knplabs/doctrine-behaviors": "dev-master", "sonata-project/doctrine-orm-admin-bundle": "dev-master", "knplabs/knp-paginator-bundle": "dev-master", "friendsofsymfony/jsrouting-bundle": "~1.1", "zendframework/zend-validator": ">=2.0.0-rc2", "zendframework/zend-barcode": ">=2.0.0-rc2"

• Reporting services 2008: ReportExecution2005.asmx does not exist

  Hi everyone, I'm trying to generate a report directly from the code (to send it by mail after). I make this in a windows service. So here is what I'm doing: Dim rview As New ReportViewer() Dim reportServerAddress As String = "http://server/Reports_client" rview.ServerReport.ReportServerUrl = New Uri(reportServerAddress) Dim paramList As New List(Of Microsoft.Reporting.WinForms.ReportParameter) paramList.Add(New Microsoft.Reporting.WinForms.ReportParameter("param1", t.Value)) paramList.Add(New Microsoft.Reporting.WinForms.ReportParameter("CurrentDate", Date.Now)) Dim reportsDirectory As String = "AppName.Reports" Dim reportPath As String = String.Format("/{0}/{1}", reportsDirectory, reportName) rview.ServerReport.ReportPath = reportPath rview.ServerReport.SetParameters(paramList) 'This is where I get the exception Dim mimeType, encoding, extension, deviceInfo As String Dim streamids As String() Dim warnings As Microsoft.Reporting.WinForms.Warning() deviceInfo = "<DeviceInfo><SimplePageHeaders>True</SimplePageHeaders></DeviceInfo>" Dim format As String = "PDF" Dim bytes As Byte() = rview.ServerReport.Render(format, deviceInfo, mimeType, encoding, extension, streamids, warnings) When debugging this code, I can see it throws a MissingEndpointException where I make the SetParameters(paramList) with this message: The attempt to connect to the report server failed.

• DataSet does not support System.Nullable<>

  - by a_m0d

  I'm trying to set the DataSource for a Crystal Reports report, but I've run into a few problems. I've been following a guide written by Mohammad Mahdi Ramezanpour, and have managed to get all the way to the last part now (setting the DataSource). However, I have a problem that Mohammad does not seem to have - when I pass the results of my query to the report, I end up with the following exception: DataSet does not support System.Nullable< This is the query I am using: public IQueryable<Part> GetPartsToDisplayOnStockReport() { return from part in db.Parts where part.showOnStockReport == true select part; } and the way I pass it to the Report: public ActionResult ViewStockReport() { StockReport stockReport = new StockReport(); var parts = ordersRepository.GetPartsToDisplayOnStockReport().ToList(); stockReport.SetDataSource(parts); Stream stream = stockReport.ExportToStream(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat); return File(stream, "application/pdf"); } I have also tried changing my query to this code, in the hope that it would fix my problem: return (from part in db.Parts where part.showOnStockReport == true select part) ?? db.Parts.DefaultIfEmpty(); but it still complained about the same problem. How can I pass the results of this query to my report, to use it as a data source? Also, if each of my Parts object contains other objects / collections of other objects, will I be able to reference them in the report with a datasource like this?

• iTextSharp 5.0 Footer is not displaying

  - by Rick Make

  I am trying to create a simple footer that would display on the bottom of each page of the pdf document. I created a class that inherits from PdfPageEventHelper and it is set properly because the OnEndPage() method is called. But my temporary footer is not displaying. Is there something wrong that I am doing in my OnEndPage() method: public override void OnEndPage(PdfWriter writer, Document document) { base.OnEndPage(writer, document); int pageN = writer.PageNumber; String text = "Page " + pageN + " of "; float len = bf.GetWidthPoint(text, 8); Rectangle pageSize = document.PageSize; cb.SetRGBColorFill(100, 100, 100); cb.BeginText(); cb.SetFontAndSize(bf, 8); cb.SetTextMatrix(pageSize.GetLeft(40), pageSize.GetBottom(30)); cb.ShowText(text); cb.EndText(); cb.AddTemplate(template, pageSize.GetLeft(40) + len, pageSize.GetBottom(30)); cb.BeginText(); cb.SetFontAndSize(bf, 8); cb.ShowTextAligned(PdfContentByte.ALIGN_RIGHT, "Printed On " + PrintTime.ToString(), pageSize.GetRight(40), pageSize.GetBottom(30), 0); cb.EndText(); }

• kanban scrumish tool(s) to get started

  - by Davide

  After investigating a little bit scrum and kanban, I finally read this answer and decided to start using kanban, picking something from scrum (note that I'm working mostly by myself, and I do have read this question and its answers). Now, my question is: which tool would be best to get started? whiteboard and postit agilezen.com JIRA with greenhopper a spreadsheet (possibly on Google Docs) brightgreenprojects.com Agilo Target Process something else (please specify) Notes about each: I would lean towards the whiteboard, but there are several drawbacks (e.g. cannot make automatic charts, time measurements, metrics, and sometimes I work from home - where I need it most - and it's not convenient to carry :-) I don't want to remember another username/password (I promised to myself to signup only to OpenID-enabled services) My employer has JIRA but my group doesn't use it - I might ask for an account (it shouldn't require another password) and maybe later involve the rest of the group. But I don't know if they are using greenhopper and if it's a big deal installing it. I generally hate spreadsheets maybe overkill? I'd be happy to have a localhost instance, but it could be problematic to give access to the whole group (per network/firewalls) - not a deal-breaker but surely a concern What I'd like to get from this? being more productive tracking how much time I spend in any given task, possibly discussing the issue with my supervisor tracking what "blocks" me most often immediately see where I am compared to my schedule manage in a better way my long todo list (e.g. answering faster to the "what I should do next?" question) Do you have any suggestion? Note on the scrumish tag: read the Henrik Kniberg's PDF. He first introduced the definition of scrumish on page 9.

• Dynamically create and save image with Django and PIL/Django-Photologue

  - by Travis

  I want to generate a page of html with dynamic content and then save the result as an image as well as display the page to the user. So, user signs up to attend conference and gives their name and org. That data is combined with html/css elements to show what their id badge for the conference will look like (their name and org on top of our conference logo background) for preview. Upon approval, the page is saved on the server to an image format (PNG, PDF or JPG) to be printed onto a physical badge by an admin later. I am using Django and django-photologue powered by PIL. The view might look like this # app/views.py def badgepreview(request, attendee_id): u = User.objects.get(id=attendee_id) name = u.name org = u.org return render_to_response('app/badgepreview.html', {'name':name,'org':org,}, context_instance = RequestContext(request), ) The template could look like this {# templates/app/badgepreview.html #} {% extends "base.html" %} {% block page_body %} <div style='background:url(/site_media/img/logo_bg.png) no-repeat;'> <h4>{{ name }}</h4> <h4>{{ org }}</h4> </div> {% endblock %} simple, but how do I save the result? Or is there a better way to get this done?

• input type file alternative and file upload best practice

  - by Ioxp

  Background: I am working on a file upload page that will extend an existing web portal. This page will allow for an end user to upload files from there local computer to our network (the files will not be stored on the web server, rather a remote workstation). The end user will have the ability to view the data that they have submitted by hyper-linking the files that have been uploaded on this page. Question 1: Is there an ASP.net alternative to the <input type="file" runat="server" /> HTML tag? The reason for asking is i would rather use an image button and display the file as an asp label on the portal to keep with a consistent style. Question 2: So i understand that giving the end user the ability to upload files to the server and then turn around to show them the data that they posted poses a security threat. So far i am using the id.PostedFile.ContentType and the file extension to reject the data if its not an accepted format (i.e. "text/plain", "application/pdf", "application/vnd.ms-excel", or "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"). Also the location where the files are uploaded to has a sufficient amount of virus and malware protection and this is not a concern. What, from the C# point of view, additional steps should i take to ensure that the end user cant take advantage and compromise the system in regards to allowing them to upload files?

• Exporting from SSRS 2008 ReportViewer to Excel Causes Duplicate Columns

  - by Daniel Coffman

  I have a report that groups months by quarters, so each quarter has three months and the display of the months under the quarter is toggled by the quarter header. It looks just fine in the ReportViewer, but when exporting to Excel the first month in the quarter with data is duplicated and appended to the end of the quarter group. Here is what it looks like in the ReportViewer (with Quarters 2 and 4 expanded, note May and June do not have any data and show blank columns by design): http://i.imgur.com/MykZE.png This is how it looks when exported to Excel: http://i.imgur.com/zfLuk.png The collapsed Quarter should only show the LAST month in the quarter. You can see that in the Excel export July is inserted in Q1 even though it should be hidden entirely since that quarter is collapsed, December is appended to Q2, January is inserted into Q3, and April is duplicated and appended to Q4. Exporting the any format OTHER than Excel works correctly and does not insert these columns. A similar bug for rows was filed and marked as "by design": http://connect.microsoft.com/SQLServer/feedback/details/508823/reporting-services-2008-group-by-export-to-excel-duplicate-rows-csv-ok-pdf-ok How do I stop the export to Excel feature from inserting these duplicate columns?

• Source-to-source compiler framework wanted

  - by cheungcc_2000

  Dear all, I used to use OpenC++ (http://opencxx.sourceforge.net/opencxx/html/overview.html) to perform code generation like: Source: class MyKeyword A { public: void myMethod(inarg double x, inarg const std::vector<int>& y, outarg double& z); }; Generated: class A { public: void myMethod(const string& x, double& y); // generated method below: void _myMehtod(const string& serializedInput, string& serializedOutput) { double x; std::vector<int> y; // deserialized x and y from serializedInput double z; myMethod(x, y, z); } }; This kind of code generation directly matches the use case in the tutorial of OpenC++ (http://www.csg.is.titech.ac.jp/~chiba/opencxx/tutorial.pdf) by writing a meta-level program for handling "MyKeyword", "inarg" and "outarg" and performing the code generation. However, OpenC++ is sort of out-of-date and inactive now, and my code generator can only work on g++ 3.2 and it triggers error on parsing header files of g++ of higher version. I have looked at VivaCore, but it does not provide the infra-structure for compiling meta-level program. I'm also looking at LLVM, but I cannot find documentation that tutor me on working out my source-to-source compilation usage. I'm also aware of the ROSE compiler framework, but I'm not sure whether it suits my usage, and whether its proprietary C++ front-end binary can be used in a commercial product, and whether a Windows version is available. Any comments and pointers to specific tutorial/paper/documentation are much appreciated.

• Merge Word Documents (Office Interop & .NET), Keeping Formatting

  - by mbmccormick

  I'm having some difficulty merging multiple word documents together using Microsoft Office Interop Assemblies (Office 2007) and ASP.NET 3.5. I'm able to merge the documents, but some of my formatting is missing (namely the fonts and images). My current merge code is shown below. private void CombineDocuments() { object wdPageBreak = 7; object wdStory = 6; object oMissing = System.Reflection.Missing.Value; object oFalse = false; object oTrue = true; string fileDirectory = @"C:\documents\"; Microsoft.Office.Interop.Word.Application WordApp = new Microsoft.Office.Interop.Word.Application(); Microsoft.Office.Interop.Word.Document wDoc = WordApp.Documents.Add(ref oMissing, ref oMissing, ref oMissing, ref oMissing); string[] wordFiles = Directory.GetFiles(fileDirectory, "*.doc"); for (int i = 0; i < wordFiles.Length; i++) { string file = wordFiles[i]; wDoc.Application.Selection.Range.InsertFile(file, ref oMissing, ref oMissing, ref oMissing, ref oFalse); wDoc.Application.Selection.Range.InsertBreak(ref wdPageBreak); wDoc.Application.Selection.EndKey(ref wdStory, ref oMissing); } string combineDocName = Path.Combine(fileDirectory, "Merged Document.doc"); if (File.Exists(combineDocName)) File.Delete(combineDocName); object combineDocNameObj = combineDocName; wDoc.SaveAs(ref combineDocNameObj, ref m_WordDocumentType, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing); } I don't care necessarily how this is accomplished. It could output via PDF if it had to. I just want the formatting to carry over. Any help or hints that you could provide me with would be appreciated! Thanks!

• Storing a digital signature for bookings on a web based system

  - by Duncan

  I have a web based bookings system built for a UK higher education client to allow students to sign out equipment (laptops, camera's etc). It's been in use successfully for a couple of years, in the current workflow equipment is collected and the booking is printed, signed by the student and kept until the equipment is returned. They are emailed a pdf copy of the booking and reminders if equipment is outstanding. Students can login and prebook equipment using their university LDAP credentials, the booking is then authorised by staff for later collection, but can also walk in and have equipment booked out by staff. They would like to remove the signed paper part of the process and replace this with some sort of digital signature. The suggestion was a graphics tablet but with a web based system this would require a local software package and in my view be impractical. My thought is that students would enter their LDAP username and password upon collection of the equipment, verifying their identity and effectively digitally signing the booking. My question is what would be best to store as a signature or whether to simply authenticate the user and use a boolean flag to indicate that this has been done could be deemed sufficient?

• ScriptSharp ClockLabel example with 0.6.2

  - by Hugh Powell

  Hi folks, I'm developing in Visual Studio 2010 and I've just downloaded and installed Script# 0.6.2 for VS 2010. I'm trying to follow the clock example in the Read Me pdf but can't get it to compile. I've created a new Script# Class Library project inside my solution called Clock, renamed the .cs file to ClockBehaviour and added the following code as per the example: using System; using System.DHTML; using ScriptFX; using ScriptFX.UI; namespace Clock { public class ClockBehavior : Behavior { private int _intervalCookie; public ClockBehavior(DOMElement domElement, string id) : base(domElement, id) { _intervalCookie = Window.SetInterval(OnTimer, 1000); } public override void Dispose() { if (_intervalCookie != 0) { Window.ClearInterval(_intervalCookie); } base.Dispose(); } private void OnTimer() { DateTime dateTime = new DateTime(); DOMElement.InnerHTML = dateTime.Format("T"); } } } When I try and compile the project I get errors saying that the System.DHMTL, ScriptFX and ScriptFX.UI namespaces could not be found (and some others, but I guess by fixing these errors the others will fall out). It feels like I'm not referencing the correct projects/dlls. In the References for the project I have mscorlib and Script.Web. I've tried using the object browser find the classes (such as Behavior) in other namespaces but with no luck. I've added all of the .dlls from the ScriptSharp folder in Program Files but the namespaces still can't be found. Any help would be very much appreciated, Thanks, Hugh
