• How do I put data from multiple records into different columns?

  - by Bryan

  My two tables are titled analyzed and analyzedCopy3. I'm trying to put information from analyzedCopy3 into multiple columns in analyzed. Sample data from analyzedCopy3: readings_miu_id OriginalCol ColRSSIz 110001366 Frederick Road -108 110001366 Steel Street 110001366 Fifth Ave. 110001508 Steel Street -104 What I want to do is put the top 3 OriginalCol, ColRSSIz combinations into columns that I have in the table analyzed. In analyzed there is only one record for each unique readings_miu_id. Any ideas? Thanks in advance. Additional Info: By "top 3 OriginalCol, ColRSSIz combinations" I mean the first 3 combinations with the highest value in the ColRSSIz column. For any readings_miu_id there could be anywhere from 1 row of information to 6 rows of information. So at most I'm only wanting the top 3. If there is less than 3 rows for the readings_miu_id then the other columns need to be blank. Query that generates the table "analyzed": strSql4 = " SELECT readings_miu_id, Count(readings_miu_id) as NumberOfReads, First(PercentSuccessz) as PercentSuccess, First(Readingz)as Reading, First(MIUwindowz) as MIUwindow, First(SNz) as SN, First(Noisez) as Noise, First(RSSIz) as RSSI, First(ColRSSIz) as ColRSSI, First(MIURSSIz) as MIURSSI, First(Col1z) as Col1, First(Col1RSSIz) as Col1RSSI, First(Col2z) as Col2, First(Col2RSSIz) as Col2RSSI, First(Col3z) as Col3, First(Col3RSSIz) as Col3RSSI, First(Firmwarez) as Firmware, First(CFGDatez) as CFGDate, First(FreqCorrz) as FreqCorr, First(Activez) as Active, First(MeterTypez) as MeterType, First(OriginColz) as OriginCol, First(ColIDz) as ColID, First(Ownagez) as Ownage, First(SiteIDz) as SiteID, First(PremIDz) as PremID, First(prem_group1z) as prem_group1, First(prem_group2z) as prem_group2, First(ReadIDz) as ReadID, First(prem_addr1z) as prem_addr1 " & _ "INTO analyzed " & _ "FROM analyzedCopy2 " & _ "GROUP BY readings_miu_id, PremIDz; " DoCmd.SetWarnings False DoCmd.RunSQL strSql4 DoCmd.SetWarnings True

• How to use wget to grab copy of Google Code site documents?

  - by Alex Reynolds

  I have a Google Code project which has a lot of wiki'ed documentation. I would like to create a copy of this documentation for offline browsing. I would like to use wget or a similar utility. I have tried the following: $ wget --no-parent \ --recursive \ --page-requisites \ --html-extension \ --base="http://code.google.com/p/myProject/" \ "http://code.google.com/p/myProject/" The problem is that links from within the mirrored copy have links like: file:///p/myProject/documentName This renaming of links in this way causes 404 (not found) errors, since the links point to nowhere valid on the filesystem. What options should I use instead with wget, so that I can make a local copy of the site's documentation and other pages?

• Deprecated Methods in Code Base

  - by Jamie Taylor

  A lot of the code I've been working on recently, both professionally (read: at work) and in other spheres (read: at home, for friends/family/etc, or NOT FOR WORK), has been worked on, redesigned and re-implemented several times - where possible/required. This has been in an effort to make things smaller, faster more efficient, better and closer to spec (when requirements have changed). A down side to this is that I now have several code bases that have deprecated method blocks (and in some places small objects). I'm looking at making this code maintainable and easy to roll back on changes. I'm already using version control software in both instances, but I'm left wondering if there are any specific techniques that have been used by others for keeping the superseded methods without increasing the size of compiled outputs? At the minute, I'm simply wrapping the old code in C style multi line comments. Here's an example of what I mean (C style, psuedo-code): void main () { //Do some work //Foo(); //Deprecated method call Bar(); //New method } /***** Deprecated code ***** /// Summary of Method void Foo() { //Do some work } ***** Deprecated Code *****/ /// Summary of method void Bar() { //Do some work } I've added a C style example, simply because I'm more confident with the C style languages. I'm trying to put this question across as language agnostic (hence the tag), and would prefer language agnostic answers, if possible - since I see this question as more of a techniques and design question. I'd like to keep the old methods and blocks for a bunch of reasons, chief amongst them being the ability to quickly restore an older working method in the case of some tests failing, or some unforeseen circumstance. Is there a better way to do this (that multi line comments)? Are there any tools that will allow me to store these old methods in separate files? Is that even a good idea?

• C# 5.0 Async/Await Demo Code

  - by Paulo Morgado

  I’ve published the sample code I use to demonstrate the use of async/await in C# 5.0. You can find it here. Projects PauloMorgado.AyncDemo.WebServer This project is a simple web server implemented as a console application using Microsoft ASP.NET Web API self hosting and serves an image (with a delay) that is accessed by the other projects. This project has a dependency on Json.NET due to the fact the the Microsoft ASP.NET Web API hosting has a dependency on Json.NET. The application must be run on a command prompt with administrative privileges or a urlacl must be added to allow the use of the following command: netsh http add urlacl url=http://+:9090/ user=machine\username To remove the urlacl, just use the following command: netsh http delete urlacl url=http://+:9090/ PauloMorgado.AsyncDemo.WindowsForms This Windows Forms project contains three regions that must be uncommented one at a time: Sync with WebClient This code retrieves the image through a synchronous call using the WebClient class. Async with WebClient This code retrieves the image through an asynchronous call using the WebClient class. Async with HttpClient with cancelation This code retrieves the image through an asynchronous call with cancelation using the HttpClient class.

• LLBLGen Pro and JSON serialization

  - by FransBouma

  I accidentally removed a reply from my previous blogpost, and as this blog-engine here at weblogs.asp.net is apparently falling apart, I can't re-add it as it thought it would be wise to disable comment controls on all posts, except new ones. So I'll post the reply here as a quote and reply on it. 'Steven' asks: What would the future be for LLBLGen Pro to support JSON for serialization? Would it be worth the effort for a LLBLGenPro user to bother creating some code templates to produce additional JSON serializable classes? Or just create some basic POCO classes which could be used for exchange of client/server data and use DTO to map these back to LLBGenPro ones? If I understand the work around, it is at the expense of losing xml serialization. Well, as described in the previous post, to enable JSON serialization, you can do that with a couple of lines and some attribute assignments. However, indeed, the attributes might make the XML serialization not working, as described in the previous blogpost. This is the case if the service you're using serializes objects using the DataContract serializer: this serializer will give up to serialize the entity objects to XML as the entity objects implement IXmlSerializable and this is a no-go area for the DataContract serializer. However, if your service doesn't use a DataContract serializer, or you serialize the objects manually to Xml using an xml serializer, you're fine. When you want to switch to Xml serializing again, instead of JSON in WebApi, and you have decorated the entity classes with the data-contract attributes, you can switch off the DataContract serializer, by setting a global configuration setting: var xml = GlobalConfiguration.Configuration.Formatters.XmlFormatter; xml.UseXmlSerializer = true; This will make the WebApi use the XmlSerializer, and run the normal IXmlSerializable interface implementation.

• Is there an alternative to Google Code Search?

  - by blunders

  Per the Official Google Blog: Code Search, which was designed to help people search for open source code all over the web, will be shut down along with the Code Search API on January 15, 2012. Google Code Search is now gone, and since that makes it much harder to understand the features it presented, here's my attempt to render them via information I gathered from a cache of the page for the Search Options: The "In Search Box" just notes the syntax to type the command directly in the main search box instead of using the advance search interface. Package (In Search Box: "package:linux-2.6") Language (In Search Box: "lang:c++") (OPTIONS: any language, actionscript, ada, applescript, asp, assembly, autoconf, automake, awk, basic, bat, c, c#, c++, caja, cobol, coldfusion, configure, css, d, eiffel, erlang, fortran, go, haskell, inform, java, java, javascript, jsp, lex, limbo, lisp, lolcode, lua, m4, makefile, maple, mathematica, matlab, messagecatalog, modula2, modula3, objectivec, ocaml, pascal, perl, php, pod, prolog, proto, python, python, r, rebol, ruby, sas, scheme, scilab, sgml, shell, smalltalk, sml, sql, svg, tcl, tex, texinfo, troff, verilog, vhdl, vim, xslt, xul, yacc) File (In Search Box: "file:^.*.java$") Class (In Search Box: "class:HashMap") Function (In Search Box: "function:toString") License (In Search Box: "license:mozilla") (OPTIONS: null/any-license, aladdin/Aladdin-Public-License, artistic/Artistic-License, apache/Apache-License, apple/Apple-Public-Source-License, bsd/BSD-License, cpl/Common-Public-License, epl/Eclipse-Public-License, agpl/GNU-Affero-General-Public-License, gpl/GNU-General-Public-License, lgpl/GNU-Lesser-General-Public-License, disclaimer/Historical-Permission-Notice-and-Disclaimer, ibm/IBM-Public-License, lucent/Lucent-Public-License, mit/MIT-License, mozilla/Mozilla-Public-License, nasa/NASA-Open-Source-Agreement, python/Python-Software-Foundation-License, qpl/Q-Public-License, sleepycat/Sleepycat-License, zope/Zope-Public-License) Case Sensitive (In Search Box: "case:no") (OPTIONS: yes, no) Also of use in understanding the search tool would be the still live FAQs page for Google Code Search. Is there any code search engine that would fully replace Google Code Search's features?

• Is there a measure of code rot?

  - by DarenW

  I'm dealing, again, with a messy C++ application, tons of classes with confusing names, objects have pointers into each other and all over, longwinded Boost and STL data types, etc. (Pause and consider your favorite terror of messy legacy code. We probably have it.) The phrase "code rot" oft comes to mind when I work on this project. Is there a quantitative way to measure code rot? I wouldn't expect anything highly meaningful or scientific, since no other measure of code productivity or quality is so fine. I'm not looking for a mere opposite of measures of code quality, but specifically a measure of how many bad things happened after a series of maintenance software "engineers" have had turns hacking at the code. A general measure applying to any language, or many languages, would be great. If there's no such thing, at least for C++, which is a better than average language for creating messes. Maybe something involving a measure of topology of how objects connect during runtime, a count of chunks of commented out code, how mane files a typical variable's usage is scattered over, I don't know... but surely now, a decade into the 21st Century, someone has attempted to define some sort of rot measure. It would be especially interesting to automate a series of svn checkouts, measure the "rottenosity" of each, and plot the decay over time.

• As a solo programmer, of what use can Gerrit be?

  - by s.d

  Disclaimer: I'm aware of the questions How do I review my own code? and What advantages do continuous integration tools offer on a solo project?. I do feel that this question aims at a different set of answers though, as it is about a specific software, and not about general musings about the use of this or that practice or tech stack. I'm a solo programmer for an Eclipse RCP-based project. To be able to control myself and the quality of my software, I'm in the process of setting up a CSI stack. In this, I follow the Eclipse Common Build Infrastructure guidelines, with the exception that I will use Jenkins rather than Hudson. Sticking to these guidelines will hopefully help me in getting used to the Eclipse way of doing things, and I hope to be able to contribute some code to Eclipse in the future. However, CBI includes Gerrit, a code review software. While I think it's really helpful for teams, and I will employ it as soon as the team grows to at least two developers, I'm wondering how I could use it while I'm still solo. Question: Is there a use case for Gerrit that takes into account solo developers? Notes: I can imagine reviewing code myself after a certain amount of time to gain a little distance to it. This does complicate the workflow though, as code will only be built once it's been passed through code review. This might prove to be a "trap" as I might be tempted to quickly push bad code through Gerrit just to get it built. I'm very interested in hearing how other solo devs have made use of Gerrit.

• Smarty: Configurable Comments and Code Templates

  - by Martin Fousek

  Hello, today we would like to show you few improvements we have prepared in PHP Smarty Framework for NetBeans 7.3. So let's talk about adjustable toggle comment action and code templates. Configurable Comments As some of you requested we implemented toggle comment action with adjustable behavior. In NetBeans 7.3 you can choose in Options between commenting as a "Smarty comments everywhere" or "Language sensitive comments" in Smarty Templates. Toggle comment language sensitive: Toggle comment as Smarty comment everywhere: Code Templates In NetBeans 7.3 we will provide by default many code templates inside Smarty templates or directly inside Smarty tags. Available should be code templates for all built-in or custom functions and modifiers of Smarty 3.x. Besides that you should be able to define additional custom templates easily in Options -> Editor -> Code Templates for "Smarty Templates" or directly for "Smarty Markup" (which means code templates inside Smarty tag). You can also take advantage of selection's template which are able to wrap your code with chosen Smarty tag. That's all for today. As always, please test it and report all the issues or enhancements you find in NetBeans BugZilla (component php, subcomponent Smarty).

• Where to put code documentation?

  - by Patrick

  I am currently using two systems to write code documentation (am using C++): Documentation about methods and class members are added next to the code, using the Doxygen format. On a server Doxygen is run on the sources so the output can be seen in a web browser Overview pages (describing a set of classes, the structure of the application, example code, ...) is added to a Wiki I personally think that this approach is easy because the documentation about members and classes is really close to the code, while the overview pages are really easy to edit in the Wiki (and it's also easy to add images, tables, ...). A web browser allows you to see both documentations. My co-worker now suggests to put everything in Doxygen, because we can then create one big help file with everything in it (using either Microsoft's HTML WorkShop or Qt Assistant). My concern is that editing Doxygen-style documentation is much harder (compared to Wiki), especially when you want to add tables, images, ... (or is there a 'preview' tool for Doxygen that doesn't require you to generate the code before you can see the result?) What do big open-source (or closed source) projects use to write their code documentation? Do they also split this up between Doxygen-style and a Wiki? Or do they use another system? What is the most appropriate way to expose the documentation? Via a Web server/browser, or via a big (several 100MB) help file? Which approach do you take when writing code documentation?

• Generic software code style enforcer

  - by FuzziBear

  It seems to me to be a fairly common thing to do, where you have some code that you'd like to automatically run through a code style tool to catch when people break your coding style guide(s). Particularly if you're working on code that has multiple languages (which is becoming more common with web-language-x and javascript), you generally want to apply similar code style guides to both and have them enforced. I've done a bit of research, but I've only been able to find tools to enforce code style guidelines (not necessarily applying the code style, just telling you when you break code style guidelines) for a particular language. It would seem to me a reasonably trivial thing to do by just using current IDE rules for syntax highlighting (so that you don't check style guide rules inside quotes or strings, etc) and a whole lot of regexes to enforce some really generic things. Examples: if ( rather than if( checking lines with only whitespace Are there any tools that do this kind of really generic style checking? I'd prefer it to be easily configurable for different languages (because like it or not, some things would just not work cross language) and to add new "rules" to check new things.

• Legacy Code Retreat Questions

  - by MarkPearl

  I recently heard of the concept of a Legacy Code Retreat. Since I have attended and helped facilitate some normal Code Retreats I thought it might be interesting in trying a Legacy Code Retreat, but I have a few questions on how a legacy CR differs from a normal one. If anyone has attended a Legacy CR and has some suggestions on how best to host these event’s please leave a comment on what has worked for you in the past or if you have any answers to my questions below… Should you restrict the languages that people can do the sessions in? In the normal CR’s I have been involved in the past we have had people attend and code in their programming language of choice. A normal CR lends itself to  this because each session starts with no code. With a legacy CR each session seems to start with an existing code base. Is there some sort of limitation on the languages that people can work in during the sessions? If not, how do you give them a base to start from? What happens as the beginning of each session? In the normal CR that I have attended each session would have a constraint set on it – i.e. no if statements used, no primitives, etc. With a legacy CR it seems more like patterns for refactoring are learned. Does the facilitator explain the pattern used before the session starts or are they just given a code base to start from and an objective to achieve

• How to refactor a myriad of similar classes

  - by TobiMcNamobi

  I'm faced with similar classes A1, A2, ..., A100. Believe it or not but yeah, there are roughly hundred classes that almost look the same. None of these classes are unit tested (of course ;-) ). Each of theses classes is about 50 lines of code which is not too much by itself. Still this is way too much duplicated code. I consider the following options: Writing tests for A1, ..., A100. Then refactor by creating an abstract base class AA. Pro: I'm (near to totally) safe by the tests that nothing goes wrong. Con: Much effort. Duplication of test code. Writing tests for A1, A2. Abstracting the duplicated test code and using the abstraction to create the rest of the tests. Then create AA as in 1. Pro: Less effort than in 1 but maintaining a similar degree of safety. Con: I find generalized test code weird; it often seems ... incoherent (is this the right word?). Normally I prefer specialized test code for specialized classes. But that requires a good design which is my goal of this whole refactoring. Writing AA first, testing it with mock classes. Then inheriting A1, ..., A100 successively. Pro: Fastest way to eliminate duplicates. Con: Most Ax classes look very much the same. But if not, there is the danger of changing the code by inheriting from AA. Other options ... At first I went for 3. because the Ax classes are really very similar to each other. But now I'm a bit unsure if this is the right way (from a unit testing enthusiast's perspective).

• Mechanics of reasoning during programming interviews

  - by user129506

  This is not the usual "I don't want to write code during an interview", in this question the assumption is that I need to write code during an interview (think about the level of rewriting the quicksort or mergesort from scratch) I know how the algorithm work or I have a basic idea of how I should start working from there, i.e. I don't remember the algorithm by heart I noticed that even on a whiteboard, I always end up writing bugged code or code that doesn't compile. If there's a typo, whatever I usually live with that.. but when there's a crash due to some uncaught particular case I end up losing confidence in my skills. I realize that perhaps interviewers might want to look at how I write code and/or how I solve problems rather than proof-compiling my whiteboard code, but I'd like to ask how should I approach the above problem in mental terms, i.e. what mental steps should I follow when writing code for an interview with the two bullet points above. There must be a unique and agreed series of steps I should follow to avoid getting stuck/caught into particular exception cases (limit cases) that might end up wasting my time and my energies rather than focusing on the overall algorithm for the general case. I hope I made my point clear

• Invariant code contracts – using class-wide contracts

  - by DigiMortal

  It is possible to define invariant code contracts for classes. Invariant contracts should always hold true whatever member of class is called. In this posting I will show you how to use invariant code contracts so you understand how they work and how they should be tested. This is my randomizer class I am using to demonstrate code contracts. I added one method for invariant code contracts. Currently there is one contract that makes sure that random number generator is not null. public class Randomizer {     private IRandomGenerator _generator;       private Randomizer() { }       public Randomizer(IRandomGenerator generator)     {         _generator = generator;     }       public int GetRandomFromRangeContracted(int min, int max)     {         Contract.Requires<ArgumentOutOfRangeException>(             min < max,             "Min must be less than max"         );           Contract.Ensures(             Contract.Result<int>() >= min &&             Contract.Result<int>() <= max,             "Return value is out of range"         );           return _generator.Next(min, max);     }       [ContractInvariantMethod]     private void ObjectInvariant()     {         Contract.Invariant(_generator != null);     } } Invariant code contracts are define in methods that have ContractInvariantMethod attribute. Some notes: It is good idea to define invariant methods as private. Don’t call invariant methods from your code because code contracts system does not allow it. Invariant methods are defined only as place where you can keep invariant contracts. Invariant methods are called only when call to some class member is made! The last note means that having invariant method and creating Randomizer object with null as argument does not automatically generate exception. We have to call at least one method from Randomizer class. Here is the test for generator. You can find more about contracted code testing from my posting Code Contracts: Unit testing contracted code. There is also explained why the exception handling in test is like it is. [TestMethod] [ExpectedException(typeof(Exception))] public void Should_fail_if_generator_is_null() {     try     {         var randomizer = new Randomizer(null);         randomizer.GetRandomFromRangeContracted(1, 4);     }     catch (Exception ex)     {         throw new Exception(ex.Message, ex);     } } Try out this code – with unit tests or with test application to see that invariant contracts are checked as soon as you call some member of Randomizer class.

• Simple Preferred time control using silverlight 3.

  - by mohanbrij

  Here I am going to show you a simple preferred time control, where you can select the day of the week and the time of the day. This can be used in lots of place where you may need to display the users preferred times. Sample screenshot is attached below. This control is developed using Silverlight 3 and VS2008, I am also attaching the source code with this post. This is a very basic example. You can download and customize if further for your requirement if you want. I am trying to explain in few words how this control works and what are the different ways in which you can customize it further. File: PreferredTimeControl.xaml, in this file I have just hardcoded the controls and their positions which you can see in the screenshot above. In this example, to change the start day of the week and time, you will have to go and change the design in XAML file, its not controlled by your properties or implementation classes. You can also customize it to change the start day of the week, Language, Display format, styles, etc, etc. File: PreferredTimeControl.xaml.cs, In this control using the code below, first I am taking all the checkbox from my form and store it in the Global Variable, which I can use across my page. List<CheckBox> checkBoxList; #region Constructor public PreferredTimeControl() { InitializeComponent(); GetCheckboxes();//Keep all the checkbox in List in the Load itself } #endregion #region Helper Methods private List<CheckBox> GetCheckboxes() { //Get all the CheckBoxes in the Form checkBoxList = new List<CheckBox>(); foreach (UIElement element in LayoutRoot.Children) { if (element.GetType().ToString() == "System.Windows.Controls.CheckBox") { checkBoxList.Add(element as CheckBox); } } return checkBoxList; } Then I am exposing the two methods which you can use in the container form to get and set the values in this controls. /// <summary> /// Set the Availability on the Form, with the Provided Timings /// </summary> /// <param name="selectedTimings">Provided timings comes from the DB in the form 11,12,13....37 /// Where 11 refers to Monday Morning, 12 Tuesday Morning, etc /// Here 1, 2, 3 is for Morning, Afternoon and Evening respectively, and for weekdays /// 1,2,3,4,5,6,7 where 1 is for Monday, Tuesday, Wednesday, Thrusday, Friday, Saturday and Sunday respectively /// So if we want Monday Morning, we can can denote it as 11, similarly for Saturday Evening we can write 36, etc /// </param> public void SetAvailibility(string selectedTimings) { foreach (CheckBox chk in checkBoxList) { chk.IsChecked = false; } if (!String.IsNullOrEmpty(selectedTimings)) { string[] selectedString = selectedTimings.Split(','); foreach (string selected in selectedString) { foreach (CheckBox chk in checkBoxList) { if (chk.Tag.ToString() == selected) { chk.IsChecked = true; } } } } } /// <summary> /// Gets the Availibility from the selected checkboxes /// </summary> /// <returns>String in the format of 11,12,13...41,42...31,32...37</returns> public string GetAvailibility() { string selectedText = string.Empty; foreach (CheckBox chk in GetCheckboxes()) { if (chk.IsChecked == true) { selectedText = chk.Tag.ToString() + "," + selectedText; } } return selectedText; }   In my example I am using the matrix format for Day and Time, for example Monday=1, Tuesday=2, Wednesday=3, Thursday = 4, Friday = 5, Saturday = 6, Sunday=7. And Morning = 1, Afternoon =2, Evening = 3. So if I want to represent Morning-Monday I will have to represent it as 11, Afternoon-Tuesday as 22, Morning-Wednesday as 13, etc. And in the other way to set the values in the control I am passing the values in the control in the same format as preferredTimeControl.SetAvailibility("11,12,13,16,23,22"); So this will set the checkbox value for Morning-Monday, Morning-Tuesday, Morning-Wednesday, Morning-Saturday, Afternoon of Tuesday and Afternoon of Wednesday. To implement this control, first I have to import this control in xmlns namespace as xmlns:controls="clr-namespace:PreferredTimeControlApp" and finally put in your page wherever you want, <Grid x:Name="LayoutRoot" Style="{StaticResource LayoutRootGridStyle}"> <Border x:Name="ContentBorder" Style="{StaticResource ContentBorderStyle}"> <controls:PreferredTimeControl x:Name="preferredTimeControl"></controls:PreferredTimeControl> </Border> </Grid> And in the code behind you can just include this code: private void InitializeControl() { preferredTimeControl.SetAvailibility("11,12,13,16,23,22"); } And you are ready to go. For more details you can refer to my code attached. I know there can be even simpler and better way to do this. Let me know if any other ideas. Sorry, Guys Still I have used Silverlight 3 and VS2008, as from the system I am uploading this is still not upgraded, but still you can use the same code with Silverlight 4 and VS2010 without any changes. May be just it will ask you to upgrade your project which will take care of rest. Download Source Code.   Thanks ~Brij

  I'm trying to add Dojo Toolkit to Zend Framework application, in my Bootstrap.php I defined following settings: protected function _initDoctype() { $this->bootstrap('view'); $view = $this->getResource('view'); Zend_Dojo::enableView($view); $view->doctype('XHTML1_STRICT'); $view ->headLink() ->appendStylesheet('/assets/css/global.css') ; $view ->dojo() ->enable() ->setCdnVersion('1.5') ->addStyleSheetModule('dijit.themes.claro') ; } All JavaScript functionality included correctly and working fine, however styling of forms and other widgets looks incomplete, no background,no images and no text styles, just basic layout defined. Did I missed something here?

• Milliseconds in DateTime.Now on .NET Compact Framework always zero?

  - by Marcel

  Hi all, i want to have a time stamp for logs on a Windows Mobile project. The accuracy must be in the range a hundred milliseconds at least. However my call to DateTime.Now returns a DateTime object with the Millisecond property set to zero. Also the Ticks property is rounded accordingly. How to get better time accuracy? Remember, that my code runs on on the Compact Framework, version 3.5. I use a HTC touch Pro 2 device.

• My first .net web app - should I go straight to MVC framework (c.f. ASP.net)

  - by Greg

  Hi, I'm done some WinForms work in C# but now moving to have to develop a web application front end in .NET (C#). I have experience developing web apps in Ruby on Rails (& a little with Java with JSP pages & struts mvc). Should I jump straight to MVC framework? (as opposed to going ASP.net) That is from the point of view of future direction for Microsoft & as well ease in ramping up from myself. Or if you like, given my experience to date, what would the pros/cons for me re MVC versus ASP.net? thanks

• Using Yii framework, what would be a right way to process an attribute before displaying it using CH

  - by Karolis

  Say I have this line of code in the view. <?php echo CHtml::activeTextField($model,'start_time'); ?> start_time is a UNIX timestamp. When just displaying it in a view I can apply functions like date() on it. Where should I apply the formatting when I'm displaying it in a form, by using the above line of code? (This case of timestamps/dates might be special, but I'm also interested in how would one go about if it wasn't a date and I just want to work with "value in database" < "different representations of the value in different views. Thanks =)

• What is the autoload class names structure, for the root "library" dir in a Zend Framework 1.10.2 pr

  - by Doron

  I have a project I created with Zend Framework 1.10.2. I usually use the application/models directory for new model files I create, and the auto loading is fine, so for example - My_Model_SampleClass is located application/models/SampleClass.php. However, I have just created a custom Exception class, and it does not fit in the models directory inside the application dir (at least the way I see it, I could be logically wrong), so I've created it in the root "library" dir, but I can't seem to find the correct class name + file name to use, so auto loading will be done correctly. BTW, I use a namespace for all custom classes I use, let's assume it's "My".

• Entity with Guid ID is not inserted by NHibernate

  - by DanK

  I am experimenting with NHibernate (version 2.1.0.4000) with Fluent NHibernate Automapping. My test set of entities persists fine with default integer IDs I am now trying to use Guid IDs with the entities. Unfortunately changing the Id property to a Guid seems to stop NHibernate inserting objects. Here is the entity class: public class User { public virtual int Id { get; private set; } public virtual string FirstName { get; set; } public virtual string LastName { get; set; } public virtual string Email { get; set; } public virtual string Password { get; set; } public virtual List<UserGroup> Groups { get; set; } } And here is the Fluent NHibernate configuration I am using: SessionFactory = Fluently.Configure() //.Database(SQLiteConfiguration.Standard.InMemory) .Database(MsSqlConfiguration.MsSql2008.ConnectionString(@"Data Source=.\SQLEXPRESS;Initial Catalog=NHibernateTest;Uid=NHibernateTest;Password=password").ShowSql()) .Mappings(m => m.AutoMappings.Add( AutoMap.AssemblyOf<TestEntities.User>() .UseOverridesFromAssemblyOf<UserGroupMappingOverride>())) .ExposeConfiguration(x => { x.SetProperty("current_session_context_class","web"); }) .ExposeConfiguration(Cfg => _configuration = Cfg) .BuildSessionFactory(); Here is the log output when using an integer ID: 16:23:14.287 [4] DEBUG NHibernate.Event.Default.DefaultSaveOrUpdateEventListener - saving transient instance 16:23:14.291 [4] DEBUG NHibernate.Event.Default.AbstractSaveEventListener - saving [TestEntities.User#<null>] 16:23:14.299 [4] DEBUG NHibernate.Event.Default.AbstractSaveEventListener - executing insertions 16:23:14.309 [4] DEBUG NHibernate.Event.Default.AbstractSaveEventListener - executing identity-insert immediately 16:23:14.313 [4] DEBUG NHibernate.Persister.Entity.AbstractEntityPersister - Inserting entity: TestEntities.User (native id) 16:23:14.321 [4] DEBUG NHibernate.AdoNet.AbstractBatcher - Opened new IDbCommand, open IDbCommands: 1 16:23:14.321 [4] DEBUG NHibernate.AdoNet.AbstractBatcher - Building an IDbCommand object for the SqlString: INSERT INTO [User] (FirstName, LastName, Email, Password) VALUES (?, ?, ?, ?); select SCOPE_IDENTITY() 16:23:14.322 [4] DEBUG NHibernate.Persister.Entity.AbstractEntityPersister - Dehydrating entity: [TestEntities.User#<null>] 16:23:14.323 [4] DEBUG NHibernate.Type.StringType - binding null to parameter: 0 16:23:14.323 [4] DEBUG NHibernate.Type.StringType - binding null to parameter: 1 16:23:14.323 [4] DEBUG NHibernate.Type.StringType - binding 'ertr' to parameter: 2 16:23:14.324 [4] DEBUG NHibernate.Type.StringType - binding 'tretret' to parameter: 3 16:23:14.329 [4] DEBUG NHibernate.SQL - INSERT INTO [User] (FirstName, LastName, Email, Password) VALUES (@p0, @p1, @p2, @p3); select SCOPE_IDENTITY();@p0 = NULL, @p1 = NULL, @p2 = 'ertr', @p3 = 'tretret' and here is the output when using a Guid: 16:50:14.008 [4] DEBUG NHibernate.Event.Default.DefaultSaveOrUpdateEventListener - saving transient instance 16:50:14.012 [4] DEBUG NHibernate.Event.Default.AbstractSaveEventListener - generated identifier: d74e1bd3-1c01-46c8-996c-9d370115780d, using strategy: NHibernate.Id.GuidCombGenerator 16:50:14.013 [4] DEBUG NHibernate.Event.Default.AbstractSaveEventListener - saving [TestEntities.User#d74e1bd3-1c01-46c8-996c-9d370115780d] This is where it silently fails, with no exception thrown or further log entries. It looks like it is generating the Guid ID correctly for the new object, but is just not getting any further than that. Is there something I need to do differently in order to use Guid IDs? Thanks, Dan.

• How do I move Zend Framework From Development to Production?

  - by dirtylogic

  I'm just wondering if anyone else has had problems moving the Zend Framework from development to production. I changed my docroot to the public folder, updated my library path, but it's still not working out for me. The IndexController is working just fine, but my ServiceController is giving me an internal server error. ServiceController <?php class ServiceController extends Zend_Controller_Action { public function amfAction() { require_once APPLICATION_PATH . '/models/MyClass.php'; $srv = new Zend_Amf_Server(); $srv->setClass('Model_MyClass', 'MyClass'); echo $srv->handle(); exit; } }

• Foreign key not stored in child entity (one-to-many)

  - by Kamil Los

  Hi, I'm quite new to hibernate and have stumbled on this problem, which I can't find solution for. When persisting parent object (with one-to-many relationship with child), the foreign-key to this parent is not stored in child's table. My classes: Parent.java @javax.persistence.Table(name = "PARENT") @Entity public class PARENT { private Integer id; @javax.persistence.Column(name = "ID") @Id @GeneratedValue(strategy=GenerationType.AUTO) public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } private Collection<Child> children; @OneToMany(mappedBy = "parent", fetch = FetchType.EAGER, cascade = {CascadeType.ALL}) @Cascade({org.hibernate.annotations.CascadeType.ALL}) public Collection<Child> getChildren() { return children; } public void setChildren(Collection<Child> children) { this.children = children; } } Child.java @javax.persistence.Table(name = "CHILD") @Entity @IdClass(Child.ChildId.class) public class Child { private String childId1; @Id public String getChildId1() { return childId1; } public void setChildId1(String childId1) { this.childId1 = childId1; } private String childId2; @Id public String getChildId2() { return childId2; } public void setChildId2(String childId2) { this.childId2 = childId2; } private Parent parent; @ManyToOne @javax.persistence.JoinColumn(name = "PARENT_ID", referencedColumnName = "ID") public Parent getParent() { return parent; } public void setParent(Operation parent) { this.parent = parent; } public static class ChildId implements Serializable { private String childId1; @javax.persistence.Column(name = "CHILD_ID1") public String getChildId1() { return childId1; } public void setChildId1(String childId1) { this.childId1 = childId1; } private String childId2; @javax.persistence.Column(name = "CHIILD_ID2") public String getChildId2() { return childId2; } public void setChildId2(String childId2) { this.childId2 = childId2; } public ChildId() { } @Override public boolean equals(Object o) { if (this == o) return true; if (o == null || getClass() != o.getClass()) return false; ChildId that = (ChildId) o; if (childId1 != null ? !childId1.equals(that.childId1) : that.childId1 != null) return false; if (childId2 != null ? !childId2.equals(that.childId2) : that.childId2 != null) return false; return true; } @Override public int hashCode() { int result = childId1 != null ? childId1.hashCode() : 0; result = 31 * result + (childId2 != null ? childId2.hashCode() : 0); return result; } } } Test.java public class Test() { private ParentDao parentDao; public void setParentDao(ParentDao parentDao) { this.parentDao = parentDao; } private ChildDao childDao; public void setChildDao(ChildDao childDao) { this.childDao = parentDao; } test1() { Parent parent = new Parent(); Child child = new Child(); child.setChildId1("a"); child.setChildId2("b"); ArrayList<Child> children = new ArrayList<Child>(); children.add(child); parent.setChildren(children); parent.setValue("value"); parentDao.save(parent); //calls hibernate's currentSession.saveOrUpdate(entity) } test2() { Parent parent = new Parent(); parent.setValue("value"); parentDao.save(parent); //calls hibernate's currentSession.saveOrUpdate(entity) Child child = new Child(); child.setChildId1("a"); child.setChildId2("b"); child.setParent(parent); childDao.save(); //calls hibernate's currentSession.saveOrUpdate(entity) } } When calling test1(), both entities get written to database, but field PARENT_ID in CHILD table stays empty. The only workaround I have so far is test2() - persisting parent first, and then the child. My goal is to persist parent and its children in one call to save() on Parent. Any ideas?
