  • Dynamically assigning properties on a non data bound ASP.NET control

    - by thinknow
    For example, let's say I have a HyperLink: <asp:HyperLink runat="server" Text="Foo" NavigateUrl="foo.aspx" /> How can I set the NavigateUrl on the server side, without having to go the code-behind? This doesn't work of course: <asp:HyperLink runat="server" Text="Foo" NavigateUrl="<%= urlString %>" /> (where urlString might be a string I created earlier in the page) And this doesn't work because the HyperLink is not within a data bound control: <asp:HyperLink runat="server" Text="Foo" NavigateUrl='<%# urlString %>' /> I guess I could just use a standard anchor element: <a href="<%= urlString %>">Foo</a> But I'd rather not mix up HTML and ASP.NET controls, and it would be handy to be able to do this for other controls. Surely there must be a way?

  • What is it that automatically checks config changes (such as those in /etc) into git?

    - by Brandon
    I remember reading on the ubuntu forums some time ago about a program to automatically check configuration changes into version control for you. It was (of course) not Ubuntu-specific. I'm pretty sure it used git, though it may have been svn, or perhaps even able to work with multiple different VCSs. My Googling has turned up nothing, and I'd rather not roll my own script if someone has already done this well. Of course I could just manually check things in, but there are reasons I'd like it done automatically. (I'm actually planning to use this for my LastSession.plist file for Safari, so when the #@$%^*&! thing crashes, and I don't restore everything, and then Leopard crashes, the fact that it has such lousy session management won't mean I lose the dozens of windows with dozens of tabs I had open.)

  • When is performance gain significant enough to implement that optimization?

    - by Zwei steinen
    Hi, following the text book, I do measure performance whenever I try optimizing my code. Sometimes, however, the performance gain is rather small and I can't decisively decide whether I should implement that optimization. For example, when a fix shortens an average response time of 100ms to 90ms under some conditions, should I implement that fix? What if it shortens 200ms to 190ms? How many condition should I try before I can conclude that it will be beneficial overall? I guess it's not possible to give a straight forward answer to this, as it depends on too many things, but is there a good rule of thumb that I should follow? Are there any guideline/best-practices?

  • Java Jersey RESTful services

    - by pHk
    Rather new to REST and Jersey, and I'm trying out some basic examples. I've got one particular question though, which I haven't really found an answer for yet (don't really know how to look for this): how would you go about storing/defining common services so that they are stateful and accessible to all/some resources? For instance, a logger instance (Log4J or whatever). Do I have to manually initialize this and store it in the HttpSession? Is there a "best practice" way of doing this so that my logger is accessible to all/some resources? Thanks a lot.

  • Drupal Views pulling Data Fields

    - by askon
    I'm a little new to drupal but have been using things like devel module and theme developer to speed up the learning process. My question, is it possible to theme an entire views BLOCK from a single views tpl.php page OR even a preprocess? When I'm grabbing the $view object I can see results $node-result, it has all of the results, but it doesn't have all my views fields. I'm missing things like, node path, taxonomy titles and paths, etc. From my understanding, Drupal wants you to individually theme EACH output field. It seems rather superfluous to create so many extra templates when I've already got over HALF of my results coming through the $view object Would outputting node over field make this easier? Or am going in the wrong direction with $view-result? Thanks!

  • Do i *have* to use ObservableCollection in Silverlight WCF client?

    - by Simon_Weaver
    When accessing Silverlight in WCF you get proxies generated with ObservableCollection Thats fine when you're databinding, but a little clumsy when you're just calling a method. For instance the following service method : [OperationContract] public SearchOrdersMsgOut SearchOrders(ShippingStatusType[] shippingStatuses, string[] orderId) { } gets generated with ObservableCollection. What! They're just parameters. Why would I ever want to 'observe' them? I'm fine if I have to do this - but it seems like there should be a way to force simple array structures when I know I'm never databinding - especially on input messages. I'd much rather do this : searchCriteria.PaymentStatus = new [] { PaymentStatusType.PaymentFailed, PaymentStatusType.Unpaid }; than this : searchCriteria.PaymentStatus = new ObservableCollection<PaymentStatusType> { PaymentStatusType.PaymentFailed, PaymentStatusType.Unpaid }; Is there a way? PS. I do actually use a SearchCriteria object for my search criteria - but I simplified for this example wondering if parameters were handled differently.

  • What are some of the practical cons to using ASMX webservices?

    - by Earlz
    Hello, at my workplace we are about to start a big project. My boss (a programmer, this is a startup) wishes to use ASMX webservices for this purpose. I do not want to start off a new program using deprecated technology and would like to show him this. I dislike WCF at this moment because it has such an extreme learning curve, but I'd rather learn it than use an unsupported technology. The problem I'm having is that I can not find any practical list of cons and downfalls when compared to WCF so that I can convince my boss to not use them. And saying "it's not as powerful" is not an adequate explanation. What exactly can it not do that we may need it to do for a webservice that is not meant to be shared externally? (as in, we don't support third-parties using our webservices unless they are using one of our clients. )

  • WCF Service Library Reference in a Web Form (asp.net)

    - by Abu Hamzah
    i am not sure if this is the correct way of doing but i read that you not suppose to have a WCF Service Library reference in your web form project rather you add endpoints to your web.config, is that true? here is what i have done: 1) create a WCF service library project 2) create a simple service called "MyService.svc" WebForm: 1) Create a web project 2) create a WCF Service and in it i have this code <%@ ServiceHost Language="C#" Service="WCFJQuery.ContactBLL.Implementation.ContactUs" Factory="System.ServiceModel.Activation.WebScriptServiceHostFactory" %> 3) right click on the web proejct and "Add Reference" and add teh MyService.dll reference from WCF service library project. is this something how you suppose to do?

  • If you're not supposed to use Regular Expressions to parse HTML, then how are HTML parsers written?

    - by Andy E
    I see questions every day asking how to parse or extract something from some HTML string and the first answer/comment is always "Don't use RegEx to parse HTML, lest you feel the wrath!" (that last part is sometimes omitted). This is rather confusing for me, I always thought that in general, the best way to parse any complicated string is to use a regular expression. So how does a HTML parser work? Doesn't it use regular expressions to parse. One particular argument for using a regular expression is that there's not always a parsing alternative (such as JavaScript, where DOMDocument isn't a universally available option). jQuery, for instance, seems to manage just fine using a regex to convert a HTML string to DOM nodes. Not sure whether or not to CW this, it's a genuine question that I want to be answered and not really intended to be a discussion thread.

  • HLSL: Enforce Constant Register Limit at Compile Time

    - by Andrew Russell
    In HLSL, is there any way to limit the number of constant registers that the compiler uses? Specifically, if I have something like: float4 foobar[300]; In a vs_2_0 vertex shader, the compiler will merrily generate the effect with more than 256 constant registers. But a 2.0 vertex shader is only guaranteed to have access to 256 constant registers, so when I try to use the effect, it fails in an obscure and GPU-dependent way at runtime. I would much rather have it fail at compile time. This problem is especially annoying as the compiler itself allocates constant registers behind the scenes, on top of the ones I am asking for. I have to check the assembly to see if I'm over the limit. Ideally I'd like to do this in HLSL (I'm using the XNA content pipeline), but if there's a flag that can be passed to the compiler that would also be interesting.

  • Multiple records with one request in RESTful system

    - by keithjgrant
    All the examples I've seen regarding a RESTful architecture have dealt with a single record. For example, a GET request to mydomain.com/foo/53 to get foo 53 or a POST to mydomain.com/foo to create a new Foo. But what about multiple records? Being able to request a series of Foos by id or post an array of new Foos generally would be more efficient with a single API request rather than dozens of individual requests. Would you "overload" mydomain.com/foo to handle requests for both a single or multiple records? Or would you add a mydomain.com/foo-multiple to handle plural POSTs and GETs? I'm designing a system that may potentially need to get many records at once (something akin to mydomain.com/foo/53,54,66,86,87) But since I haven't seen any examples of this, I'm wondering if there's something I'm just not getting about a RESTful architecture that makes this approach "wrong".

  • What is the point in using a "real" database modeling tool?

    - by cdeszaq
    We currently have a 10 year old nasty, spaghetti-code-style SQL Server database that we are soon looking to pretty much re-write from scratch as part of a re-write to a large web application. (The existing application will serve as the functional requirements for the next incarnation of the app). Some have suggested we use Visio to do all the diagramming and to generate the DDL, but others have suggested we use a dedicated database design tool, rather than a diagramming tool that is able to export DDL. Is there any benefit to using "real" DB design tools, such as ModelRight, over general tools like Visio? If so, what are those specific benefits? Edit: In a nutshell, what can real/dedicated tools do that something like Visio can't, and how much do these capabilities matter (from a best-practices standpoint, for example)

  • Easy way to apply Joomla template styling to my own content

    - by Joey Adams
    I have an application that is mainly a bunch of PHP files included in a Joomla! application by Jumi. I want to make the site look nicer, but I'd rather not reinvent the wheel. There is a RocketTheme template installed on the site, and I'd like to be able to leverage it or some of the other CSS used alongside it. Specifically, I want to decorate tables. Should I search for and include CSS classes directly into my tags by searching through the template's classes, or is there a framework I could use that automatically adds the right classes based on the current theme?

  • Getting websites to detect our mobile browser

    - by Chromatix
    I've been asked to find out a sensible way to make the majority of popular websites detect our browser - which is functionally complete, but is running on rather constrained hardware - as a "mobile" browser. The idea is that the heaviest popular websites seem to have mobile versions, which render much faster and fit better on the screen. I've looked at the inverse question, which tells me that there isn't an obvious standard way of doing it - http://www.brainhandles.com/techno-thoughts/detecting-mobile-browsers is a case in point. This is borne out by looking at a variety of User-Agent strings from popular mobile and desktop browsers. So far the best idea we can come up with is to add "Mobile" to the string somewhere, since this is the main visible difference between Safari for iPad/iPhone and for Windows/Mac. Does anyone have a better idea?

  • C# console applications all 16bit?

    - by Jon
    Hi all, I was reading up about NTVDM.exe as I build a quick test console app and it crashed on a friends machine complaining about this EXE. As I understand it all DOS cmd windows (C# console apps included) run as 16bit not 32bit. Is this true? Does this mean all my works console app back office apps are running as 16bit rather than making the most of the 32bit available? What about Windows services? As I believe we wrote it as a console app then made it run as a windows service? Thanks

  • Insert rownumber repeatedly in records in t-sql.

    - by jeff
    Hi, I want to insert a row number in a records like counting rows in a specific number of range. example output: RowNumber ID Name 1 20 a 2 21 b 3 22 c 1 23 d 2 24 e 3 25 f 1 26 g 2 27 h 3 28 i 1 29 j 2 30 k I rather to try using the rownumber() over (partition by order by column name) but my real records are not containing columns that will count into 1-3 rownumber. I already try to loop each of record to insert a row count 1-3 but this loop affects the performance of the query. The query will use for the RDL report, that is why as much as possible the performance of the query must be good. any suggestions are welcome. Thanks

  • Customising event delegates in the jQuery validation plug-in

    - by Russell
    I am currently setting up the jQuery validation plug-in for use in our project. By default, there are some events automatically set up for handling. I.e. focus in/out, key up events on all inputs fire validation. I want it to only fire when the submit button is clicked. This functionality seems to be in-built into the plug-in, which is making it difficult to do this (without modifying the plug-in code, Not What I Want To Do). I have found the eventDelegate function calls in the plugin code prototype method: $(this.currentForm) .validateDelegate(":text, :password, :file, select, textarea", "focusin focusout keyup", delegate) .validateDelegate(":radio, :checkbox, select, option", "click", delegate); When I remove these lines from the plug-in I get my result, however I would much rather do something Outside the plug-in to achieve this. Can anybody please help me? If you need any more details, please let me know. I have searched google with little success. Thanks

  • PHP getimagesize with ampersand in string creates errors

    - by RobHardgood
    I'm using the getimagesize function in PHP, and the path string contains an ampersand, which otherwise is fine. The page gives me errors where getimagesize() is called. Looking at the source code, though, I see the ampersand is being passed through as & rather than just & I presume this is causing errors because PHP doesn't need to convert it to the html tag in order to find the path, right? Here is the error: Warning: getimagesize(image.php?name=username&pic=picture) [function.getimagesize]: failed to open stream: No such file or directory

  • ezpublish for practical e-commerce?

    - by Olaseni
    For while now I have been using ezpublish as a framework, and CMS when my web projects are based on PHP, and I must say, I have grown accustomed to it because of its flexibility for most scenarios. However, I've had to build e-commerce sites now and then, and ezpublish includes a webshop that caters for the e-commerce needs of your installation, and of-course with all the tools you need to extend, should you need to. Is it worthwhile and optimal to use the inbuilt webshop for an e-commerce solution, or should I rather go with an all out e-commerce solution like Magento, which has made a significant impact in that sector?

  • Does Objective-C have a Standard Library?

    - by Roman A. Taycher
    Most somewhat modern programming languages have a standard library? It is my impression is that there isn't a decent sized standard library for Obj-C , rather that it relies mostly/all on Cocoa and that (plus people not wanting to use GNUstep) is why Obj-C is only used on macs)? Is this true/to what extent? Are there any standard obj-c collections? (note I haven't done any Obj-C programming and am not to likely to try it in the near future, I'm just curious). P.S. are there a any decent non-Cocoa/Gnustep Libraries? are they non-apple, are they open source, well documented?

  • Memory leak with preg_replace

    - by Silvio Donnini
    I'm using the preg_replace function to replace accents in a string, I'm working with UTF-8. I have incurred in what seems to be a memory leak, but I can't isolate the root cause, my code is rather simple: preg_replace( array_keys($aToNoAccents), array_values($aToNoAccents), $sText ); where $aToNoAccents is an associative array with entries like '~[A]~u' => 'A', '~[C]~u' => 'C',. My script prints this error for the above line: Fatal error: Allowed memory size of 1073741824 bytes exhausted (tried to allocate 3039 bytes) Obviously it's not a matter of increasing the allowed memory for PHP, (a 1Gb footprint is way off the scale of my application). Also, that line is executed thousands of times without problems but, just for some cases which are difficult to reproduce, it yields the error. Is anyone aware of memory problems with preg_replace and UTF-8 strings? Am I to use special care in passing actual parameters to such function? I'm using PHP 5.2.6-3 with Suhosin-Patch thanks Silvio

  • How to Access a Private Variable?

    - by SoulBeaver
    This question isn't meant to sound as blatantly insulting as it probably is right now. This is a homework assignment, and the spec sheet is scarce and poorly designed to say the least. We have a function: double refuel( int liter, GasStation *gs ) { // TODO: Access private variable MaxFuel of gs and decrement. } Sound simple enough? It should be, but the class GasStation comes with no function that accesses the private variable MaxFuel. So how can I access it anyway using the function refuel? I'm not considering creating a function setFuel( int liter ) because the teacher always complains rather energetically if I change his specification. So... I guess I have to do some sort of hack around it, but I'm not sure how to go about this without explicitely changing the only function in GasStation and giving it a parameter so that I can call it here. Any hints perhaps?

  • LRU caches in C

    - by lazyconfabulator
    I need to cache a large (but variable) number of smallish (1 kilobyte to 10 megabytes) files in memory, for a C application (in a *nix environment). Since I don't want to eat all my memory, I'd like to set hard memory limit (say, 64 megabytes) and push files into a hash table with the file name as the key and dispose of the entries with the least use. What I believe I need is an LRU cache. Really, I'd rather not roll my own so if someone knows where I can find a workable library, please point the way? Failing that, can someone provide a simple example of an LRU cache in C? Related posts indicated that a hash table with a doubly-linked list, but I'm not even clear on how a doubly-linked list keeps LRU. Side note: I realize this is almost exactly the function of memcache, but it's not an option for me. I also took a look at the source hoping to enlighten myself on LRU caching, with no success.

  • Query to show images with recent posts in Wordpress sidebar/widget

    - by Peter
    To show recent items from a Wordpress category in a widget I'm using this code... <ul> <?php $recent = new WP_Query("cat=1231&showposts=5"); while($recent->have_posts()) : $recent->the_post();?> <li><a href="<?php the_permalink() ?>" rel="bookmark"> <?php the_title(); ?> </a></li> <?php endwhile; ?> </ul> ...but how can I make this query also display the first image in each post, and is there any way to set a 'default' image in case there is no image? Is there also a way to use thumbnails here, rather than loading the full size image and using HTML to resize?

  • Building a complete online payment gateway like Paypal

    - by John Stewart
    So this question isn't about integrating an existing payment gateway into my site. This is more of a architectural question. I want to build a system similar to Paypal. Now I understand that Paypal offers a lot of features under the roof and I can't implement all of them at once. I want to implement the core functionality of Paypal and other such services. So my question is (rather discussion is) around how would one go about building such a system. Some points to discuss: Handle payments through existing banks. I am guessing that I would need access to local bank protocols to get this. Allow users to securely store and process their payments How does Paypal handle the transactions? Thoughts?
