  • Regex to use each letter only once?

    - by gtcaz
    Is it possible to construct a PCRE-style regular expression that will only match each letter in a list only once? For example, if you have the letters "lrsa" and you try matching a word list against: ^[lrsa]*m[lrsa]*$ you're going to match "lams" (valid), but also "lamas" (invalid for our purposes because you only had one "a"). If your letter set was "lrsaa", you would want to match "lamas". Is this possible with regular expressions, or should I handle it programmatically?

  • Removing Database References from an ASP.NET MVC Site

    - by Maxim Z.
    I'm building a very simple ASP.NET MVC site that doesn't require a database and doesn't have user accounts or any other special ASP.NET stuff. When I first created the site with the ASP.NET MVC 1.0 site template in Visual Studio, the web.config page was configured to automatically connect to SQL Server Express as a User Instance. Can I completely remove this dependency? If so, how do I get rid of all this database stuff?

  • Bizarre Son of Suckerfish ie6/ie7 problem - 2 letters from right-most dropdown menu also appearing o

    - by Kevin Burke
    I'm interning for an NGO in India and trying to fix their website, including updating their menu so it's not the last item on the page to load, and it's centered on the screen. Everything works well enough but when I try out my new menu in IE6, I get this weird error where the content below the menu is padded an extra 30px or so and the material in the right-most drop down appears on the far left of the screen, always visible. When I drop down the rightmost link ("Publications") the content appears both in the correct location and in the same spot on the far left of the screen, and changes color when I hover as well. It's tough to describe, so it would probably be best if you took a look: visit http://sevamandir.org/a30/aboutus.htm in your IE6/IE7 browser to see for yourself. I really appreciate your help. Also I'm using a 1000px wide monitor, if there's more hijinks going on outside that space I'd like to know about that too. I took a look at the problem again and it's even weirder than I thought. Only two letters of the bottom-most drop down menu item are shown, no matter how many items are in the left-most drop down menu. When I delete the left-most drop down menu, the bottom item from the next left-most item shows up in the same space. The padding between the menu and the content is always the same. When I hover over the real menu item, the two letters on the left hand side change color to match the hover color. Unfortunately many people that visit our website are using old browsers so IE6 support is pretty crucial, this problem is really weird though, and I would appreciate some help. I uploaded a file with the entire style.css sheet in the and HTML code below, at http://sevamandir.org/a30/aboutus.htm. Here's the relevant code: in the html head: <script> sfHover = function() { var sfEls = document.getElementById("nav").getElementsByTagName("LI"); for (var i=0; i<sfEls.length; i++) { sfEls[i].onmouseover=function() { this.className+=" sfhover"; } sfEls[i].onmouseout=function() { this.className=this.className.replace(new RegExp(" sfhover\\b"), ""); } } } if (window.attachEvent) window.attachEvent("onload", sfHover); </script> text surrounding the menu - the menu is simply <ul id="nav"><li></li></ul> etc. <!--begin catchphrase--> <div style="float:left; height:27px; width:520px; margin:0px; font:16px Arial, Helvetica, sans-serif; font-weight:bold; color:#769841;"> Transforming lives through democratic &amp; participatory development </div> <?php include("menu.php"); ?> </div><!-- end header --> <!--begin main text div--> <div id="maincontent"> Relevant menu CSS: #nav, #nav ul { font:bold 11px Verdana, sans-serif; float: left; width: 980px; list-style: none; line-height: 1; background: white; font-weight: bold; padding: 0; border: solid #769841; border-width: 0; margin: 0 0 1em 0; } #nav a { display: block; width: 140px; /*this is the total width of the upper menu*/ w\idth: 120px; /*this is the width less horizontal padding */ padding: 5px 10px 5px 10px; /*horiz padding is the 2nd & 4th items here - goes Top Right Bottom Left */ color: #ffffff; background:#b6791e; text-decoration: none; } #nav a.daddy { background: url(rightarrow2.gif) center right no-repeat; } #nav li { float: left; padding: 0; width: 140px; /*this needs to be updated to match top #nav a */ background:#b6791e; } #nav li:hover, #nav li a:hover, #nav li:hover a { background:#769841; } #nav li:hover li a { background:#ffffff; color:#769841; } #nav li ul { position: absolute; left: -999em; height: auto; width: 14.4em; w\idth: 13.9em; font-weight: bold; border-width: 0.25em; /*green border around dropdown menu*/ margin: 0; } #nav li ul a { background:#ffffff; color:#769841; } #nav li li { padding-right: 1em; width: 13em; background:#ffffff; } #nav li ul a { width: 13em; w\idth: 9em; } #nav li ul ul { margin: -1.75em 0 0 14em; } #nav li:hover ul ul, #nav li:hover ul ul ul, #nav li.sfhover ul ul, #nav li.sfhover ul ul ul { left: -999em; } #nav li:hover ul, #nav li li:hover ul, #nav li li li:hover ul, #nav li.sfhover ul, #nav li li.sfhover ul, #nav li li li.sfhover ul { left: auto; } #nav li:hover, #nav li.sfhover, { background: #769841; color:#ffe400; } #nav li a:hover, #nav li li a:hover, #nav li:hover li:hover, #nav li.sfhover a:hover { background: #769841; color:#ffe400; }

  • CSS3's border-radius property and border-collapse:collapse don't mix. How can I use border-radius to

    - by vamin
    Edit - Original Title: Is there an alternative way to achieve border-collapse:collapse in CSS (in order to have a collapsed, rounded corner table)? Since it turns out that simply getting the table's borders to collapse does not solve the root problem, I have updated the title to better reflect the discussion. I am trying to make a table with rounded corners using the CSS3 border-radius property. The table styles I'm using look something like this: table { -moz-border-radius:10px; -webkit-border-radius:10px; border-radius:10px} Here's the problem. I also want to set the border-collapse:collapse property, and when that is set border-radius no longer works (at least in Firefox)(edit- I thought this might just be a difference in mozilla's implementation, but it turns out this is the way it's supposed to work according to the w3c). Is there a CSS-based way I can get the same effect as border-collapse:collapse without actually using it? Edits: I've made a simple page to demonstrate the problem here (Firefox/Safari only). It seems that a large part of the problem is that setting the table to have rounded corners does not affect the corners of the corner td elements. If the table was all one color, this wouldn't be a problem since I could just make the top and bottom td corners rounded for the first and last row respectively. However, I am using different background colors for the table to differentiate the headings and for striping, so the inner td elements would show their rounded corners as well. Summary of proposed solutions: Surrounding the table with another element with round corners doesn't work because the table's square corners "bleed through." Specifying border width to 0 doesn't collapse the table. Bottom td corners still square after setting cellspacing to zero. Using javascript instead- works by avoiding the problem. Possible solutions: The tables are generated in php, so I could just apply a different class to each of the outer th/tds and style each corner separately. I'd rather not do this, since it's not very elegant and a bit of a pain to apply to multiple tables, so please keep suggestions coming. Possible solution 2 is to use javascript (jQuery, specifically) to style the corners. This solution also works, but still not quite what I'm looking for (I know I'm picky). I have two reservations: 1) this is a very lightweight site, and I'd like to keep javascript to the barest minimum 2) part of the appeal that using border-radius has for me is graceful degradation and progressive enhancement. By using border-radius for all rounded corners, I hope to have a consistently rounded site in CSS3-capable browsers and a consistently square site in others (I'm looking at you, IE). I know that trying to do this with CSS3 today may seem needless, but I have my reasons. I would also like to point out that this problem is a result of the w3c speficication, not poor CSS3 support, so any solution will still be relevant and useful when CSS3 has more widespread support.

  • buffer overrun throw return address

    - by user156144
    Hi, When I throw in a method A, it causes buffer overrun but when I return, it runs fine. I thought throw moves execution to the caller method so the address it goes to should be the same as return address, but i am obviuosly wrong. Is there a way to see what address throw goes to in Visual Studio debugger? Thank you

  • How can I add HTTP request caching to an application using ASIHTTPRequests?

    - by smokey_the_bear
    I'm using ASIHttpRequests and an ASINetworkQueue in an iphone app to retrieve some 100k XML files and a lot of thumbnails from a web service. I'd like to cache the requests in the style of NSURLCache. ASI doesn't seem to support caching as is, and I looked at the code and it drops to C to create the requests, so inserting the NSURLCache layer seemed tricky. What's the best way to implement this?

  • Example open source client-server code projects

    - by Ricket
    I'm still trying to determine an answer to my question from a few minutes ago, "Should client-server code be written in one 'project' or two?" and I think it would benefit me to see how other projects organize their code (and hopefully deduce the pros and cons of why they chose to do it that way). What are some open source client-server projects which might be best to look at and mimic their code organization style? Java is preferred but not required.

  • How to combine designable components with dependency injection

    - by Wim Coenen
    When creating a designable .NET component, you are required to provide a default constructor. From the IComponent documentation: To be a component, a class must implement the IComponent interface and provide a basic constructor that requires no parameters or a single parameter of type IContainer. This makes it impossible to do dependency injection via constructor arguments. (Extra constructors could be provided, but the designer would ignore them.) Some alternatives we're considering: Service Locator Don't use dependency injection, instead use the service locator pattern to acquire dependencies. This seems to be what IComponent.Site.GetService is for. I guess we could create a reusable ISite implementation (ConfigurableServiceLocator?) which can be configured with the necessary dependencies. But how does this work in a designer context? Dependency Injection via properties Inject dependencies via properties. Provide default instances if they are necessary to show the component in a designer. Document which properties need to be injected. Inject dependencies with an Initialize method This is much like injection via properties but it keeps the list of dependencies that need to be injected in one place. This way the list of required dependencies is documented implicitly, and the compiler will assists you with errors when the list changes. Any idea what the best practice is here? How do you do it? edit: I have removed "(e.g. a WinForms UserControl)" since I intended the question to be about components in general. Components are all about inversion of control (see section 8.3.1 of the UMLv2 specification) so I don't think that "you shouldn't inject any services" is a good answer. edit 2: It took some playing with WPF and the MVVM pattern to finally "get" Mark's answer. I see now that visual controls are indeed a special case. As for using non-visual components on designer surfaces, I think the .NET component model is fundamentally incompatible with dependency injection. It appears to be designed around the service locator pattern instead. Maybe this will start to change with the infrastructure that was added in .NET 4.0 in the System.ComponentModel.Composition namespace.

  • JSF 2.0 Dynamic Views

    - by Robe Eleckers
    Hello, I'm working on a web project which uses JSF 2.0, PrimeFaces and PrettyFaces as main frameworks / libraries. The pages have the following (common) structure: Header, Content, Footer. Header: The Header always contains the same menu. This menu is a custom component, which generates a recursive html <ul><li> list containing <a href="url"> html links, this is all rendered with a custom renderer. The link looks like 'domain.com/website/datatable.xhtml?ref=2'. Where the ref=2 used to load the correct content from the database. I use prettyfaces to store this request value in a backingbean. Question 1: Is it ok to render the <a href> links myself, or should I better add an HTMLCommandLink from my UIComponent and render that in the encodeBegin/End? Question 2: I think passing variables like this is not really the JSF 2.0 style, how to do this in a better way? Content: The content contains dynamic data. It can be a (primefaces) datatable, build with dynamic data from the database. It can also be a text page, also loaded from the database. Or a series of graphs. You got the point, it's dynamic. The content is based on the link pressed in the header menu. If the content is of type datatable, then I put the ref=2 variable to a DataTableBean (via prettyfaces), which then loads the correct datatable from the database. If the content is of type chart, I'll put it on the ChartBean. Question 3: Is this a normal setup? Ideally I would like to update my content via Ajax. I hope it's clear :)

  • How to automate building and deploying a BPEL application

    I need to automate the building and deployment of (several) BPEL applications to a weblogic server. I now do it using jDeveloper 11g, but I guess there should be some command line tools to do it.
