  • Most pain-free time registration software for developers ?

    - by driis
    I work as a consultant in a medium-sized firm. We need to keep track of time spent on individual tasks and which customers to bill to. Our current system for doing this is an old in-house system, that needs to be retired for various reasons. Most developers don't like registering time, so I am looking for the best tool for this job, that minimizes the time needed to register time. Must have features: Must be simple and easy to use. Must have reporting feature to use for billing. Must have an API, so we can integrate in-house tools. Registering time should be based on hours worked (ie. today, worked on Customer A, Task B from 8 AM to 12 AM). TFS integration is a plus, but not needed (ie. register time on a work item) May be open source or a paid product; doesn't really matter. What would you recommend ?

  • Writing a "Hello World" Device Driver for kernel 2.6 using Eclipse

    - by Isaac
    Goal I am trying to write a simple device driver on Ubuntu. I want to do this using Eclipse (or a better IDE that is suitable for driver programming). Here is the code: #include <linux/module.h> static int __init hello_world( void ) { printk( "hello world!\n" ); return 0; } static void __exit goodbye_world( void ) { printk( "goodbye world!\n" ); } module_init( hello_world ); module_exit( goodbye_world ); My effort After some research, I decided to use Eclipse CTD for developing the driver (while I am still not sure if it supports multi-threading debugging tools). So I: Installed Ubuntu 11.04 desktop x86 on a VMWare virtual machine, Installed eclipse-cdt and linux-headers-2.6.38-8 using Synaptic Package Manager, Created a C Project named TestDriver1 and copy-pasted above code to it, Changed the default build command, make, to the following customized build command: make -C /lib/modules/2.6.38-8-generic/build M=/home/isaac/workspace/TestDriver1 The problem I get an error when I try to build this project using eclipse. Here is the log for the build: **** Build of configuration Debug for project TestDriver1 **** make -C /lib/modules/2.6.38-8-generic/build M=/home/isaac/workspace/TestDriver1 all make: Entering directory '/usr/src/linux-headers-2.6.38-8-generic' make: *** No rule to make target vmlinux', needed byall'. Stop. make: Leaving directory '/usr/src/linux-headers-2.6.38-8-generic' Interestingly, I get no error when I use shell instead of eclipse to build this project. To use shell, I just create a Makefile containing obj-m += TestDriver1.o and use the above make command to build. So, something must be wrong with the eclipse Makefile. Maybe it is looking for the vmlinux architecture (?) or something while current architecture is x86. Maybe it's because of VMWare? As I understood, eclipse creates the makefiles automatically and modifying it manually would cause errors in the future OR make managing makefile difficult. So, how can I compile this project on eclipse?

  • Java Champion Jorge Vargas on Extreme Programming, Geolocalization, and Latin American Programmers

    - by Janice J. Heiss
    In a new interview, up on otn/java, titled “An Interview with Java Champion Jorge Vargas,” Jorge Vargas, a leading Mexican developer, discusses the process of introducing companies to Enterprise JavaBeans through the application of Extreme Programming. Among other things, he gives workshops about building code with agile techniques and creates a master project to build all apps based on Scrum, XP methods and Kanban. He focuses on building core components such as security, login, and menus. Vargas remarks, “This may sound easy, but it’s not—the process takes months and hundreds of hours, but it can be controlled, and with small iterations, we can translate customer requirements and problems of legacy systems to the new system.” In regard to his work with geolocalization, he says: “We have launched a beta program of Yumbling, a geolocalization-based app, with mobile clients for BlackBerry, iPhone, Android, and Nokia, with a Web interface. The first challenge was to design a simple universal mechanism providing information to all clients and to minimize maintenance provision to them. I try not to generalize a lot—to avoid low performance or misunderstanding in processing data. We use the latest Java EE technology—during the last five years, I’ve taught people how to use Java EE efficiently.” Check out the interview here.

  • release management system - architectural question

    - by Sonic Soul
    Every place i've worked created their own release process, and all of them worked pretty well, however it took pretty good effort (and often a dedicated team) to manage releases. I am currently at a new place, and about to design such a system, however this time the team is very lean and we won't have dedicated resources to releasing. It will be up to development manager until the system is proofed enough for other developers to use. we're using Subversion as code repository, Team City as the build server, Jira issue tracker, Oracle db. I was thinking about writing a basic workflow app, that will let developers create a new manifest which will specify the following items. release details (who, jira issues etc) workflow step (dev, test, uat, prod approved, prod released) source files that last item is where it can get hairy. especially with database scripts. Figured I'd ask if there is a good pattern, or off the shelf product that could help with the database part, or perhaps the whole process. I briefly tested Red Gate Oracle deployment tool, but it didn't work out as well as I had hoped (from 1 day of testing at least) Questions: I think I could get around releasing of our code with something like Octopus Deploy straight from Team City. I am not clear however, how I could create a simple database deployment part, that will track which version of which script (from subversion) has been deployed where. Is there already some utility I could utilize for navigating subversion to choose which scripts should be released, instead of writing one from scratch. I'd just need it to produce some manifest of paths + versions.

  • Visual web page designer for Django?

    - by Robert Oschler
    I'm just starting my Django learning so pardon me if any part of this question is off-base. I have done a lot of web searching for information on the equivalent of a visual web page designer for Django and I don't seem to be getting very far. I have experience with Delphi (Object Pascal), C, C++, Python, PHP, Java, and Javascript and have created and maintained several web sites that included MySQL database dependent content. For the longest time I've been using one of the standard WYSIWIG designers to design the actual web pages, with any needed back end programming done via Forms or AJAX calls that call server side PHP scripts. I have grown tired of the quirks, bugs, and other annoyances associated with the program. Also, I find myself hungry for the functionality and reliability a good MVC based framework would provide me so I could really express myself with custom code easily. So I am turning to Django/Python. However, I'm still a junkie for a good WYSIWIG designer for the layout of web pages. I know there are some out there that thrive on opening up a text editor, possibly with some code editor tools to assist, and pounding out pages. But I do adore a drag and drop editor for simple page layout, especially for things like embedded images, tables, buttons, etc. I found a few open source projects on GitHub but they seem to be focused on HTML web forms, not a generic web page editor. So can I get what I want here? The supreme goal would be to find not only a web page editor that creates Django compatible web pages, but if I dare say it, have a design editor that could add Python code stubs to various page elements in the style of the Delph/VCL or VB design editors. Note, I also have the Wing IDE Professional IDE, version 2.0. As a side note, if you know of any really cool, fun, or time-saving Python libraries that are designed for easy integration into Django please tell me about them. -- roschler

  • #SQLMug - Like a collectors set of 5 x geeky SQL Mugs?

    - by Greg Low
    Hi Folks,For a while, I've been wanting to get some great SQL mugs printed for SQL Down Under but I need further inspiration so here's your chance to get a collectors set of 5 SQL mugs:Send me (greg @ sqldownunder . com) a great line to go onto the mugs, along with your country and a delivery address. I'll pick the best 5 and get mugs printed with those sayings. If you're one of the 5, I'll send you a collectors set with one of each of the 5. Simple enough?Here are some ideas I've already received to get you started:Chuck Norris gets NULL. Nothing compares to him either.ALTER MUG  SET SINGLE_USER  WITH ROLLBACK IMMEDIATE;DENY CONTROL  ON OBJECT::MUG  TO public;knock knock who's there? sp_ sp_who? spid 1, spid 2, spid 3, spid 4... ALTER DATABASE CriticalDB SET ChuckNorrisMode = ON WITH NOWAIT;I'll probably cut off new entries around the end of April.

  • Do you think that exposure to BASIC can mutilate your mind? [closed]

    - by bigown
    It is practically impossible to teach good programming to students that have had a prior exposure to BASIC: as potential programmers they are mentally mutilated beyond hope of regeneration -- Edsger W. Dijkstra I have deep respect to Dijkstra but I don't agree with everything he said/wrote. I disagree specially with this quote on linked paper wrote 35 years ago about the Dartmouth BASIC implementation. Many of my coworkers or friends programmers started with BASIC, questions below have answers that indicate many programmers had their first experience on programming at BASIC. AFAIK many good programmers started at BASIC programming. I'm not talking about Visual Basic or other "modern" dialects of BASIC running on machines full of resources. I'm talking about old times BASIC running on "toy" computer, that the programmer had to worry about saving small numbers that need not be calculated as a string to save a measly byte because the computer had only a few hundreds of them, or have to use computed goto for lack of a more powerful feature, and many other things which require the programmer to think much before doing something and forcing the programmer to be creative. If you had experience with old time BASIC on a machine with limited resources (have in mind that a simple micro-controller today has much more resources than a computer in 1975, do you think that BASIC help your mind to find better solutions, to think like an engineer or BASIC drag you to dark side of programming and mutilated you mentally? Is good to learn a programming language running on a computer full of resources where the novice programmer can do all wrong and the program runs without big problems? Or is it better to learn where the programmer can't go wrong? What can you say about the BASIC have helped you to be a better/worse programmer? Would you teach old BASIC running on a 2KB (virtual) machine to a coming programmer? Sure, only exposure to BASIC is bad. Maybe you share my opinion that modern BASIC doesn't help too much because modern BASIC, as long other programming languages, gives facilities which allow the programmer doesn't think deeper. Additional information: Why BASIC?

  • SQL SERVER – Weekly Series – Memory Lane – #039

    - by Pinal Dave
    Here is the list of selected articles of SQLAuthority.com across all these years. Instead of just listing all the articles I have selected a few of my most favorite articles and have listed them here with additional notes below it. Let me know which one of the following is your favorite article from memory lane. 2007 FQL – Facebook Query Language Facebook list following advantages of FQL: Condensed XML reduces bandwidth and parsing costs. More complex requests can reduce the number of requests necessary. Provides a single consistent, unified interface for all of your data. It’s fun! UDF – Get the Day of the Week Function The day of the week can be retrieved in SQL Server by using the DatePart function. The value returned by the function is between 1 (Sunday) and 7 (Saturday). To convert this to a string representing the day of the week, use a CASE statement. UDF – Function to Get Previous And Next Work Day – Exclude Saturday and Sunday While reading ColdFusion blog of Ben Nadel Getting the Previous Day In ColdFusion, Excluding Saturday And Sunday, I realize that I use similar function on my SQL Server Database. This function excludes the Weekends (Saturday and Sunday), and it gets previous as well as next work day.

DBCC SHRINKFILE Takes Long Time to Run If you are DBA who are involved with Database Maintenance and file group maintenance, you must have experience that many times DBCC SHRINKFILE operations takes a long time but any other operations with Database are relatively quicker. mssqlsystemresource – Resource Database The purpose of resource database is to facilitates upgrading to the new version of SQL Server without any hassle. In previous versions whenever version of SQL Server was upgraded all the previous version system objects needs to be dropped and new version system objects to be created. 2009 Puzzle – Write Script to Generate Primary Key and Foreign Key In SQL Server Management Studio (SSMS), there is no option to script all the keys. If one is required to script keys they will have to manually script each key one at a time. If database has many tables, generating one key at a time can be a very intricate task. I want to throw a question to all of you if any of you have scripts for the same purpose. Maximizing View of SQL Server Management Studio – Full Screen – New Screen I had explained the following two different methods: 1) Open Results in Separate Tab - This is a very interesting method as result pan shows up in a different tab instead of the splitting screen horizontally. 2) Open SSMS in Full Screen - This works always and to its best. Not many people are aware of this method; hence, very few people use it to enhance performance. 2010 Find Queries using Parallelism from Cached Plan T-SQL script gets all the queries and their execution plan where parallelism operations are kicked up. Pay attention there is TOP 10 is used, if you have lots of transactional operations, I suggest that you change TOP 10 to TOP 50 This is the list of the all the articles in the series of computed columns.

SQL SERVER – Interview Questions and Answers – Guest Post by Malathi Mahadevan – Day 26 of 31 Malachi had asked a simple question which has several answers. Each answer makes you think and ponder about the reality of the IT world. Look at the simple question – ‘What is the toughest challenge you have faced in your present job and how did you handle it’? and its various answers. Each answer has its own story. SQL SERVER – Interview Questions and Answers – Guest Post by Rick Morelan – Day 27 of 31 Rick Morelan of Joes2Pros has written an excellent blog post on the subject how to find top N values. Most people are fully aware of how the TOP keyword works with a SELECT statement. After years preparing so many students to pass the SQL Certification I noticed they were pretty well prepared for job interviews too. Yes, they would do well in the interview but not great. There seemed to be a few questions that would come up repeatedly for almost everyone. Rick addresses similar questions in his lucid writing skills. 2012 Observation of Top with Index and Order of Resultset SQL Server has lots of things to learn and share. It is amazing to see how people evaluate and understand different techniques and styles differently when implementing. The real reason may be absolutely different but we may blame something totally different for the incorrect results. Read the blog post to learn more. How do I Record Video and Webcast How to Convert Hex to Decimal or INT Earlier I asked regarding a question about how to convert Hex to Decimal. I promised that I will post an answer with Due Credit to the author but never got around to post a blog post around it. Read the original post over here SQL SERVER – Question – How to Convert Hex to Decimal. Query to Get Unique Distinct Data Based on Condition – Eliminate Duplicate Data from Resultset The natural reaction will be to suggest DISTINCT or GROUP BY. However, not all the questions can be solved by DISTINCT or GROUP BY. Let us see the following example, where a user wanted only latest records to be displayed. Let us see the example to understand further.

  • How does the PPA fit into the scenario of publishing an application to the Ubuntu Software Center?

    - by Mridang Agarwalla
    I've been going through docs for the past couple of hours but I haven't understood what the PPA is? I have a cross-platform Java application that I'd like to publish to the Ubuntu Software Center. My application is open-source and I'm using Github. Apparently, publishing applications to the store isn't as simple as uploading a deb package - am I right? I need to create an account on Launchpad and put all my code there. I don't intend to move from Git to Bzr merely for the sake of publishing to the app store but luckily, one is able to set up source-code mirroring from Github to Launchpad. Since my application is still very premature, it'll have updates fairly often. When I build my application on my machine, do I simply go my Ubuntu App Developer page and upload the new DEB package or do they build my application from source? What exactly is the PPA for? I don't think I'll need too many of the Launchpad features so I'd like to stick to Github if possible. (Publishing for Ubuntu really isn't trivial. I can see why there are so many developers out there who haven't published their applications to the Ubuntu Software Center. Publishing an Android applications has been the easiest so far.)

Edit n°1 installed xsane (via Ubuntu Software Center), launched it and get the following: Clicking on "Help" yields: I tried 4) man sane-dll which yields No manual entry for sane-dll I uninstalled "Simple Scan": didn't help. I tried 3) but aborted due to unsettling warning ;) wasn't that brave (or desperate). Maybe it's due to 1) and I'm stuck with it? Is it really not possible that a driver for either Windoze or Mac OS would also support scanning via Ubuntu? Edit n°2 Resorted to Windows XP and the Network TWAIN Driver ScanRouter or the "lite" version (which I found elsewhere) might also work (under Linux??); but it's more than I need. Thought about WINE, but also that seems to rely on SANE... So still no luck with this device's scanning capabilities with Linux (but good enough (via xp) for my purposes)...

  • handling various frame layouts in android

    - by vaibhav
    i'm new to game development and am trying create a Contra or the old tmnt game (but a simple one) like game for android. for the game i decided to divide my main screen in three parts - upper for stats,mid for the game and lower for controls. my main.xml is <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <FrameLayout android:id="@+id/upper_bar" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="1" > </FrameLayout> <FrameLayout android:id="@+id/fl" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="0.5" > </FrameLayout> <FrameLayout android:id="@+id/low_bar" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="0.85" > </FrameLayout> </LinearLayout> so i have created the gameview and gameloopthread classes for the mid surface(which is pretty standard). my problem is that how do i draw in the upper and lower frame layouts? should i make new classes for view and thread for each layout , should i do all this in the gameview class itself or is there any better way to implement this?

  • JavaServer Faces 2.0 for the Cloud

    - by Janice J. Heiss
    A new article now up on otn/java by Deepak Vohra titled “JSF 2.0 for the Cloud, Part One,” shows how JavaServer Faces 2.0 provides features ideally suited for the virtualized computing resources of the cloud. The article focuses on @ManagedBean annotation, implicit navigation, and resource handling. Vohra illustrates how the container-based model found in Java EE 7, which allows portable applications to target single machines as well as large clusters, is well suited to the cloud architecture. From the article-- “Cloud services might not have been a factor when JavaServer Faces 2.0 (JSF 2.0) was developed, but JSF 2.0 provides features ideally suited for the cloud, for example:•    The path-based resource handling in JSF 2.0 makes handling virtualized resources much easier and provides scalability with composite components.•    REST-style GET requests and bookmarkable URLs in JSF 2.0 support the cloud architecture. Representational State Transfer (REST) software architecture is based on transferring the representation of resources identified by URIs. A RESTful resource or service is made available as a URI path. Resources can be accessed in various formats, such as XML, HTML, plain text, PDF, JPEG, and JSON, among others. REST offers the advantages of being simple, lightweight, and fast.•    Ajax support in JSF 2.0 is integrable with Software as a Service (SaaS) by providing interactive browser-based Web applications.” In Part Two of the series, Vohra will examine features such as Ajax support, view parameters, preemptive navigation, event handling, and bookmarkable URLs.Have a look at the article here.

  • 2D Side Scrolling game and "walk over ground" collision detection

    - by Fire-Dragon-DoL
    The question is not hard, I'm writing a game engine for 2D side scrolling games, however I'm thinking to my 2D side scrolling game and I always come up with the problem of "how should I do collision with the ground". I think I couldn't handle the collision with ground (ground for me is "where the player walk", so something heavily used) in a per-pixel way, and I can't even do it with simple shape comparison (because the ground can be tilted), so what's the correct way? I'know what tiles are and i've read about it, but how much should be big each tile to not appear like a stairs?Are there any other approach? I watched this game and is very nice how he walks on ground: http://www.youtube.com/watch?v=DmSAQwbbig8&feature=player_embedded If there are "platforms" in mid air, how should I handle them?I can walk over them but I can't pass "inside". Imagine a platform in mid air, it allows you to walk over it but limit you because you can't jump in the area she fits Sorry for my english, it's not my native language and this topic has a lot of keywords I don't know so I have to use workarounds Thanks for any answer Additional informations and suggestions: I'm doing a game course in this period and I asked them how to do this, they suggested me this approach (a QuadTree): -All map is divided into "big nodes" -Each bigger node has sub nodes, to find where the player is -You can find player's node with a ray on player position -When you find the node where the player is, you can do collision check through all pixels (which can be 100-200px nothing more) Here is an example, however i didn't show very well the bigger nodes because i'm not very good with photoshop :P How is this approach?

  • How to ...set up new Java environment - largely interfaces...

    - by Chris Kimpton
    Hi, Looks like I need to setup a new Java environment for some interfaces we need to build. Say our system is X and we need to interfaces to systems A, B and C. Then we will be writing interfaces X-A, X-B, X-C. Our system has a bus within it, so the publishing on our side will be to the bus and the interface processes will be taking from the bus and mapping to the destination system. Its for a vendor based system - so most of the core code we can't touch. Currently thinking we will have several processes, one per interface we need to do. The question is how to structure things. Several of the APIs we need to work with are Java based. We could go EJB, but prefer to keep it simple, one process per interface, so that we can restart them individually. Similarly SOA seems overkill, although I am probably mixing my thoughts about implementations of it compared to the concepts behind it... Currently thinking that something Spring based is the way to go. In true, "leverage a new tech if possible"-style, I am thinking maybe we can shoe horn some jruby into this, perhaps to make the APIs more readable, perhaps event-machine-like and to make the interface code more business-friendly, perhaps even storing the mapping code in the DB, as ruby snippets that get mixed in... but thats an aside... So, any comments/thoughts on the Spring approach - anything more up-to-date/relevant these days. EDIT: Looking a JRuby further, I am tempted to write it fully in JRuby... in which case do we need any frameworks at all, perhaps some gems to make things clearer... Thanks in advance, Chris

  • AJAX Control Toolkit - Globalization (Language)

    - by Guilherme Cardoso
    For those who use AjaxToolKit controls presenting a language-dependent data (the CalendarExternder with the names of the months and weeks, for example) you can change the language to be presented in a simple way. In Web.Config let's define the primary culture as follows: < system . web > <System. Web> < globalization uiCulture = "pt-pt" culture = "pt-pt" /> <Globalization UICulture = "en-us" culture = "en-us" /> ... ...  In this example I'm using Portuguese. To finish it is necessary to change our ScriptManager. Be it the ToolScriptManager AjaxToolKit or belonging to the ScriptManager's framework. NET, the properties as a vibrant and true are the EnableScriptGlobalization EnableScriptLocalization. < cc1 : ToolkitScriptManager ID = "ToolkitScriptManager1" runat = "server" EnableScriptGlobalization = "true" EnableScriptLocalization = "true" > <Cc1: ToolkitScriptManager ID = "ToolkitScriptManager1" runat = "server" EnableScriptGlobalization = "true" EnableScriptLocalization = "true"> </ cc1 : ToolkitScriptManager > </ Cc1: ToolkitScriptManager> or < asp : ScriptManager ID = "ScriptManager1" runat = "server" EnableScriptGlobalization = "true" EnableScriptLocalization = "true" > <Asp: ScriptManager ID = "ScriptManager1" runat = "server" EnableScriptGlobalization = "true" EnableScriptLocalization = "true"> </ asp : ScriptManager > </ Asp: ScriptManager>   Like hus we use the controls on AjaxToolKit, always using the Portuguese language. It is important that AjaxTookKit is updated to avoid shortages or errors in translation, though I have not updated by this error in the ModalPopup the latest version, and any controls that I have used are translated correctly.

You will get choice of Gift Card brand based on your preference and country location. Puzzle 1: What will be the outcome and why? DECLARE @x REAL; SET @x = 9E-40 SELECT @x; The outcome here is obvious as I have used negative number in assignment. What is the reason behind the same? Puzzle 2: Why will be the outcome different from Puzzle 1: DECLARE @y REAL; SET @y = 9E+40 SELECT @y; The outcome of this puzzle very different from puzzle 1  as I have used positive number. There is number six (6) in the resultset why? Msg 232, Level 16, State 2, Line 2 Arithmetic overflow error for type real, value = 90000000000000006000000000000000000000000.000000.

  • Find The Bug

    - by Alois Kraus
    What does this code print and why?             HashSet<int> set = new HashSet<int>();             int[] data = new int[] { 1, 2, 1, 2 };             var unique = from i in data                          where set.Add(i)                          select i;   // Compiles to: var unique = Enumerable.Where(data, (i) => set.Add(i));             foreach (var i in unique)             {                 Console.WriteLine("First: {0}", i);             }               foreach (var i in unique)             {                 Console.WriteLine("Second: {0}", i);             }   The output is: First: 1 First: 2 Why is there no output of the second loop? The reason is that LINQ does not cache the results of the collection but it does recalculate the contents for every new enumeration again. Since I have used state (the Hashset does decide which entries are part of the output) I do arrive with an empty sequence since Add of the Hashset will return false for all values I have already passed in leaving nothing to return a second time. The solution is quite simple: Use the Distinct extension method or cache the results by calling .ToList() or ToArray() for the result of the LINQ query. Lession Learned: Do never forget to think about state in Where clauses!

  • Enum.HasFlag

    - by Scott Dorman
    An enumerated type, also called an enumeration (or just an enum for short), is simply a way to create a numeric type restricted to a predetermined set of valid values with meaningful names for those values. While most enumerations represent discrete values, or well-known combinations of those values, sometimes you want to combine values in an arbitrary fashion. These enumerations are known as flags enumerations because the values represent flags which can be set or unset. To combine multiple enumeration values, you use the logical OR operator. For example, consider the following: public enum FileAccess { None = 0, Read = 1, Write = 2, }   class Program { static void Main(string[] args) { FileAccess access = FileAccess.Read | FileAccess.Write; Console.WriteLine(access); } } The output of this simple console application is: The value 3 is the numeric value associated with the combination of FileAccess.Read and FileAccess.Write. Clearly, this isn’t the best representation. What you really want is for the output to look like: To achieve this result, you simply add the Flags attribute to the enumeration. The Flags attribute changes how the string representation of the enumeration value is displayed when using the ToString() method. Although the .NET Framework does not require it, enumerations that will be used to represent flags should be decorated with the Flags attribute since it provides a clear indication of intent. One “problem” with Flags enumerations is determining when a particular flag is set. The code to do this isn’t particularly difficult, but unless you use it regularly it can be easy to forget. To test if the access variable has the FileAccess.Read flag set, you would use the following code: (access & FileAccess.Read) == FileAccess.Read Starting with .NET 4, a HasFlag static method has been added to the Enum class which allows you to easily perform these tests: access.HasFlag(FileAccess.Read) This method follows one of the “themes” for the .NET Framework 4, which is to simplify and reduce the amount of boilerplate code like this you must write.

  • Technical development decision for my newly established software company

    - by test test
    I have a new software company where I am planning to develop CRM system. So I have settled down on the technological approach I am going to use:- I will use an open source Java-based CRM engine. I will use a third party reporting tool named JasperReports for providing reports capabilities for the CRM. I will develop the interface and any customization which the customer might ask for using asp.net mvc framework since my knowledge and experience are based on asp.net. And I will use the CRM API to integrate my asp.net web application with the Java-based CRM. I have developed a simple demo which integrate these three main components (CRM engine, asp.net application and the reporting tool) and they worked well. But I am afraid of the following risk that I might face if I go with the above approach: I should hire developers with different skills and experience: Developers with Java skills to be able to modify the Java-based CRM and writing plug-ins -when needed- to extend the CRM capabilities. Other developers with asp.net skills to be able to build the application such as application forms, the portal from where users will be able to start the CRM processes, searching capabilities, etc. So might the above point raise some risks when I start hiring a new team and start building the CRM application, OR I am on the right track at this early stage?

  • C# with keyword equivalent

    - by oazabir
    There’s no with keyword in C#, like Visual Basic. So you end up writing code like this: this.StatusProgressBar.IsIndeterminate = false; this.StatusProgressBar.Visibility = Visibility.Visible; this.StatusProgressBar.Minimum = 0; this.StatusProgressBar.Maximum = 100; this.StatusProgressBar.Value = percentage; Here’s a work around to this: With.A<ProgressBar>(this.StatusProgressBar, (p) => { p.IsIndeterminate = false; p.Visibility = Visibility.Visible; p.Minimum = 0; p.Maximum = 100; p.Value = percentage; }); Saves you repeatedly typing the same class instance or control name over and over again. It also makes code more readable since it clearly says that you are working with a progress bar control within the block. It you are setting properties of several controls one after another, it’s easier to read such code this way since you will have dedicated block for each control. It’s a very simple one line function that does it: public static class With { public static void A<T>(T item, Action<T> work) { work(item); } } You could argue that you can just do this: var p = this.StatusProgressBar; p.IsIndeterminate = false; p.Visibility = Visibility.Visible; p.Minimum = 0; p.Maximum = 100; p.Value = percentage; But it’s not elegant. You are introducing a variable “p” in the local scope of the whole function. This goes against naming conventions. Morever, you can’t limit the scope of “p” within a certain place in the function.
