  • XAML-based applications - Event Naming Conventions for C#

    - by user118190
    For event handling, I am starting to see many coders doing this: XButton.Click += OnXButtonClicked() ... void OnXButtonClicked() { ... } Where did this On_ convention come from? It just doesn't feel right in terms of methods. I am starting to see this as well and am wondering what others thought: XButton.Click += HandleXButtonClick() ... void HandleXButtonClick() { ... } When using intellisense, Visual Studio handles these like so: XButton.Click += XButton_Click; ... void XButton_Click(object sender, RoutedEventArgs e) { ... } I am seeking some advice on these naming conventions and would greatly appreciate some advice.

  • Safari 5 vs. Safari 4 : Are there any compatibility differences?

    - by Cole
    I recently obtained a Mac so I could test our sites on Safari and Firefox for Mac OS. Now that Safari 5 is out, I'm not sure what I should do about upgrading. I presume what works on Safari 5 works on Safari 4, but I can't be sure, and vice versa. So, I don't know if I should upgrade and test on Safari 5 or keep on with Safari 4. Are there any major differences between these two version in terms of CSS (2.1) handling or JavaScript? When do you think the majority of people will have Safari 5 instead of 4? All thoughts appreciated.

  • A way to ensure that a system tray icon is removed... guaranteed

    - by Brian R. Bondy
    Is there a way to guarantee that your system tray icon is removed? To add the system tray icon you do: Shell_NotifyIcon(NIM_ADD, &m_tnd); To remove the system tray icon you do: Shell_NotifyIcon(NIM_DELETE, &m_tnd); What I want to know: what if you application crashes? The icon stays in your system tray until you mouse over. Is there a way to guarantee that the icon will be removed, even when the application crashes? I would prefer not to use structured exception handling for various reasons. Another case that I want to handle is when the process is killed, but doesn't necessarily crash.

  • How to get data from a incoming email and then copy data to some directory

    - by Zegnhabi
    First of all, I have some time reading this page and I find very interesting, the content also has many questions and are very entertaining. My question is about handling my incoming mail server, no matter if you use PHP, Perl, or Python. I do not care, what if I want is the result which should be as close to: I send an email to [email protected], this post will add a case such as photos, then when the mail reaches the server, the server takes to process mail and copy the attached files, in this case the photos to a folder / home / public_html / photos and then, if possible notify you if it was successful or not. In advance thank you very much. And I hope and can be done. ñ_ñ

  • Is there a slick way to deploy my silverlight app and change settings programmatically?

    - by MIke S.
    I am fairly new to web development. I am at the point of deployment (for testing). I have a few places (maybe 4 places) where I had to add a URI that was non-relative into the appliation. So now, at deployment, those need to be changed. Is there a slick way of handling this? By slick I mean not manually going through the app and changing the URIs or a blanket find and replace (too risky). I only have 4 places to change now, but this could easily change and cause deployment issues. I am using a Microsoft technology stack. Silverlight, ASP.NET, RIA, etc. Development is done in Visual Studio 2010. I noticed that the web projects have a nifty transformation for the web.config...which is nice. Is there an equivalent mechanism for silverlight resources? Any other ways? Any thoughts?

  • Notify via email if something wrong got happened in the shell script

    - by Nevzz03
    fileexist=0 for i in $( ls /data/read-only/clv/daily/Finished-HADOOP_EXPORT_&processDate#.done); do mv /data/read-only/clv/daily/Finished-HADOOP_EXPORT_&processDate#.done /data/read-only/clv/daily/archieve-wip/ fileexist=1 done --some other script below Above is the shell script I have in which in the for loop, I am moving some files. I want to notify myself via email if something wrong got happened in the moving process, as I am running this script on the Hadoop Cluster, so it might be possible that cluster went down while this was running etc etc. So how can I have better error handling mechanism in this shell script? Any thoughts?

  • Unboxing object containing a value which is known to be assignable to an integer variable

    - by Wim Coenen
    If I have an object instance and I know it is actually a boxed integer, then I can simply cast it back to int like this: object o = GetSomethingByName("foo"); int i = (int)o; However, I don't actually know that the value is an integer. I only know that it can be assigned to an integer. For example, it could be a byte, and the above code would throw InvalidCastException in that case. Instead I would have to do this: object o = GetSomethingByName("foo"); int i = (int)(byte)o; The value could also be a short, or something else which can be assigned to an int. How do I generalize my code to handle all those cases (without handling each possibility separately)?

  • error reporting issues

    - by SunnyOne
    I'm still entangled in error handling problems. After having read and tried lots of different scripts, I still do not have an overall insight on the problem. I made a syntax error on purpose and get the following error message : Parse error: syntax error, unexpected '{' in /home/directory/public_html/mypage.php on line 10 To understand how it work, as a first step, I'd like to remove this message(which I'am able to do) and replace it by a custom one. How can I customize this message ? Thanks a lot.

  • Set the mouseover Attribute of a div using JQuery

    - by Abs
    Hello all, I would like to set an attribute for a div. I have done this: $('#row-img_1').onmouseover = function (){ alert('foo'); }; $('#row-img_2').onmouseout = function (){ alert('foo2'); }; However, the above has not worked, it does not alert when mouse is over or when it moves out. I have also tried the $('#row-img_1').attr(); and I could not get this to work either. I am aware that I should be using a more effective event handling system but my divs are dynamically generated. Plus this is a small project. ;) Thanks all for any help.

  • minifying patched javascript files

    - by Stacia
    I'm writing a Rails app and I've partially integrated in this nice little patch to the in line ajax editor: http://inplacericheditor.box.re/ The problem is, on that page I have tinymce, prototype and scriptaculous included. In Firefox at least there's a big lag when all this stuff is loading. I was hoping to fix it by compressing the files so I checked out a plugin for rails called Smurf. It seemed to do what it was supposed to do nicely, but it choked on the little patch files that are included with the Ajax editor thing. THe patch files look like this: Object.extend(Ajax.InPlaceEditor.prototype, { handleAJAXFailure: function(transport) Alternatively, should I just be catching them instead of worrying about minfying them? I know I'm running on development and that Apache would maybe be handling serving the js files differently..It just seems like a lot of things to serve on one page.

  • Looking for a specific kind of WEB framework, no malarkey please

    - by Hello you all men
    We do maintenence on a number of systems. I'm finally in a place where I'm teh fucking boss for once, and have to design a large system that will have a long maintenance contract. There's a couple of tasks I find myself always repeating: 1) similar tasks for users with JS and those without 2) similar things for contents and rss/atom feeds, etc. To combat these I will need appropriate handling of assets (think JS files, CSS, themes/templates, etc.), excellent auth/user systems, javascript/ajax forethought, appropriate model setups. Codeigniter fails on many of these. Basically, with enough time I could build this system with Zend, but I'm curious what else is out there as Zend is also kind of a heavy-weight. We need something that is Rapid but maintainable, CodeIgniter is not maintainable. We will have a lot of AJAX APIs in place for the design team to play with. At first I thought jQuery was cool, but now I'm looking at Dojo.

  • .net MVC, dealing with json and Areas

    - by JoseMarmolejos
    When not using areas dealing with the url for the JsonResults from the clientside is not much of a pain, usually you can get away with hardcoding the url into your json calls and get away with it. Problem arises when you have different areas and you don't want to update all your links when you move a controller (and its views) from one area to the other. I'm not very satisfied with the way I'm handling this scenario by having this chunk of code inside every view: <script type="text/javascript"> var ControllerActions = { JsonSearch: '<%= Url.Action("JsonSearch") %>/', JsonDelete: '<%= Url.Action("JsonDelete") %>/', Edit: '<%= Url.Action("Edit") %>/', Delete: '<%= Url.Action("Delete") %>/' } </script> While it does work no matter where I place the views/controllers I wonder if there's a more elegant to do this.

  • What is the difference between panic and an assert?

    - by acidzombie24
    Go doesn't provide assertions. They are undeniably convenient, but our experience has been that programmers use them as a crutch to avoid thinking about proper error handling and reporting. However it has print and println which does panic like print, aborts execution after printing panicln like println, aborts execution after printing Isnt that the same thing as an assert? Why would they claim the above but have panic? i can see it leading to the same problems but adding an error msg to the end of it which can easily be abused. Am i missing something?

  • How do I read long lines from a text file in C++?

    - by sonofdelphi
    I am using the following code for reading lines from a text-file. What is the best method for handling the case where the line is greater than the limit SIZE_MAX_LINE? void TextFileReader::read(string inFilename) { ifstream xInFile(inFilename.c_str()); if(!xInFile){ return; } char acLine[SIZE_MAX_LINE + 1]; while(xInFile){ xInFile.getline(acLine, SIZE_MAX_LINE); if(xInFile){ m_sStream.append(acLine); //Appending read line to string } } xInFile.close(); }

  • apply CSS style to particular elements dynamically

    - by WHITECOLOR
    I have a div with paragraphs inside: <div> <p>...</p> <p>...</p> </div> I want dynamically to apply a certain style to paragraphs inside this div. Is it possible to do that without handling each paragraph element, but just attach somehow style to div element and all inside paragraphs would be affected? Maybe with jquery. It sounds for me like dynamical change of the stylesheet, is it possbile? Thanks.

  • Connecting to TFS via ASP.NET, jQuery and Phonegap

    - by Tony D.
    I want to develop a mobile application that would allow the user the ability to run a suite of automated test cases housed in TFS. This is something I thought of this morning so it's all still very preliminary. But I'm curious as to what would be the best route for something like this? Or if it's even possible? Because the mobile devices from the users will vary from iphones to droids, I would probably want to incorporate something like Phonegap for it's cross platform capabilities. My initial thought was to develop in ASP.net/C# (which would be stored on a remote server), and have jQuery make calls to that server. Not sure if that would be the most appropriate way of handling this. I'm not too familiar with JSON but I have seen it as a suggestion on various sites to handle the returned data. Any thoughts or suggestions are appreciated. Thanks.

  • How to disable typing in values in Dojo's NumberSpinner?

    - by callie16
    Hi, is there a way to disable typing in of values in the NumberSpinner of Dojo? Or is there a way for me to set back a previous value to it? Here's a sample situation: I have a spinner where the range is 1-3. However, the user types in an invalid value... say, a letter. The usual error handling happens. However, if the user deletes the value and focuses out (e.g. goes to another widget/control/etc. in the page), the spinner stays blank. Either I reset it to the last valid value or I disable typing so that the user can just use the up and down arrows to manipulate the widget. Any thoughts? Thanks!

  • Firefox DOMParser problem

    - by Michael
    For some reason DOMParser is adding some additional #text elements for each newline \n for this url http://rt.com/Root.rss ...as well as many other RSS I've tried. I checked cnn/bbc feeds, they don't have newlines and dom parser handling them nicely. So I have to add the following before parsing it var xmlText = htmlText.replace(/\n[ ]*/g, ""); var xmlDoc = parser.parseFromString(xmlText, "text/xml"); Server is returning text/xml. var channel = xmlDoc.documentElement.childNodes[0]; this returning \n without my code above and channel with correction.

  • [C#] Creating standalone, console (shell) for domain-specific operations

    - by mr.b
    Say that I have a system service, and I want to offer a low-level maintenance access to it. For that purpose, I'd like to create a standalone, console application that somehow connects to server process and lets user type in commands, allow it to use auto-completion and auto-suggestion on single/double TAB press (just like linux bash shell, mysql cli, cmd.exe, and countless others), allow command line editing capabilities (history, cursor keys to move around text..), etc. Now, it's not that much of a problem to create something like that by rolling my own from scratch, handling user input, scanning pressed keys, and doing correct actions. But, why reinvent the wheel? Is there some library/framework that helps with this kind of problems, just like readline library that offers improved command-line editing capabilities under linux? Of course, this new "shell" would respond only to valid, domain-specific commands, and would suggest valid arguments, options, switches... Any ideas? Thanks!

  • VB.NET Inputbox - How to identify when the Cancel Button is pressed?

    - by The Sasquatch
    I have a simple windows application that pops up an input box for users to enter in a date to do searches. How do I identify if the user clicked on the Cancel button, or merely pressed OK without entering any data as both appear to return the same value? I have found some examples of handling this in VB 6 but none of them really function in the .NET world. Ideally I would like to know how to handle the empty OK and the Cancel seperately, but I would be totally ok with just a good way to handle the cancel.

  • Why is there "data" and "newtype" in Haskell?

    - by martingw
    To me it seems that a newtype definition is just a data definition that obeys some restrictions (only one constructor and such), and that due to these restrictions the runtime system can handle newtypes more efficiently. Ok, and the handling of pattern matching for undefined values is slightly different. But suppose Haskell would only knew data definitions, no newtypes: Couldn't the compiler find out for himself whether a given data definition obeys these restrictions, and automatically treat it more efficiently? I'm sure I'm missing out on something, these Haskell designers are so clever, there must be some deeper reason for this...

  • How to distinguish date at midnight from date w/o time in Oracle?

    - by Swiety
    I would like to distinguish date at midnight (i.e. '12/05/2010 00:00:00') from date without time specified (i.e. '12/05/2010'). This value is provided by user, sometimes it is only date which is important, sometimes it is date and time and later the application is expected to show the time only when it was explicitly provided. So for the following inputs I would expect the following outputs: for '12/05/2010' I would expect '12/05/2010' for '12/05/2010 09:23' I would expect '12/05/2010 09:23' for '12/05/2010 00:00' I would expect '12/05/2010 00:00' I know I can model it in two separate columns, date and time, but I was wondering was there any way of handling this in single date column?

  • Programming Exercises for Learning Purposes?

    - by cam
    Are there any programming exercises that apply to any language? Before I got my first job, I thought I knew C# pretty well, then I was thrown right into the deep end, and now I know I have a good command over the language. I would like to apply the same method to other languages, but unfortunately, I'm sort of stuck with C# at work. Ideally, something similar (but broader in scope) to Project Euler is ideal. Project Euler helped me learn a ton of C++/F#, some math, algorithms, handling bignums, etc. I'm looking for something like this.
