• Wordpress auto excerpts from post content?

  - by Scott B

  I'm trying to create an auto generated post excerpt from the current page's post content using a function in my theme's header file. The post excerpt will be used as the page's meta description. Can someone give me an idea of how you might go about this once you've got the post content into a string variable? The somewhat tricky part is that, in order to predict a viable stopping point for the post excerpt, I'd like to specify that the cutoff point be the end of the first paragraph of text. And for that reason, it does not make sense to load the entire post content into the string I'm using. Can I grab the first paragraph without having to load the entire post content string? And I'm not certain how to test for that in php. Would regex be the only way?

• How to determine what in my script is blocking my HTML rendering?

  - by Vicki

  I have a web application that uses quite a bit of JavaScript. When the page loads, it's very clear visually that something is blocking the rendering of a particular portion of the web site. This portion is generated by a Tabber Tabify JavaScript library. How can I determine what's blocking the HTML rendering specifically so that I can modify my code to prevent this blocking? Can I use Firebug, or some other tool, to walk through my HTML/JavaScript to determine where the HTML rendering is being blocked and if so, how? UPDATE: YSlow gives my web-application a score of "A" and Page Speed give a score of 94/100. UPDATE 2: The live site is linked below. http://www.uptownelite.com/index.uncompressed.html?city=Dallas,TX What I'm specifically referring too is the actual Tabs themselves being rendering (and NOT the panel content inside the tab panes). It seems strange to me that the Tab headings themselves are taking so long to generate on the first (empty cache) page load.

• Password reset by email without a database table

  - by jpatokal

  The normal flow for resetting a user's password by mail is this: Generate a random string and store it in a database table Email string to user User clicks on link containing string String is validated against database; if it matches, user's pw is reset However, maintaining a table and expiring old strings etc seems like a bit of an unnecessary hassle. Are there any obvious flaws in this alternative approach? Generate a MD5 hash of the user's existing password Email hash string to user User clicks on link containing string String is validated by hashing existing pw again; if it matches, user's pw is reset Note that the user's password is already stored in a hashed and salted form, and I'm just hashing it once more to get a unique but repeatable string. And yes, there is one obvious "flaw": the reset link thus generated will not expire until the user changes their password (clicks the link). I don't really see why this would be a problem though -- if the mailbox is compromised, the user is screwed anyway.

• Link objects as fields in UML diagram

  - by fearofawhackplanet

  I'm trying to generate a diagram for a design document. I've generated a class diagram in VS. At the moment it's just a bunch of unconnected boxes as there isn't any inheritance going on. It feels like it would be more useful if I could show how the objects interact through properties and parameters. As an example, a Boy class has a method Kiss which takes a Girl object. How can I show that Boy and Girl interact by connecting this in the diagram? Is there a notation for this in UML? Or is there another type of diagram that shows this? Can I make VS draw this connection for me somehow? Or is this a silly/useless idea? It just doesn't feel like a proper diagram unless it's got some lines on it somewhere :)

• SpringSource Roo Controller Removal

  - by Steve Wall

  Hello, Environment: Windows XP, SpringSource Tool Suite 2.3.2, Roo 1.0.2.Release, Java 1.6.0_10, tc Server 6.0 I'm using the canned Roo generated code. I created an entity and associated controller. Then deleted both classes. The problem I'm seeing is the Roo created home page still shows the "Create/List" section for the deleted classes. I'm executing this within the tc Server, within Eclipse. Any ideas on how to get Roo to update the home page? Thanks, Steve

• ASP.NET - ViewState: empty placeholder generates view state

  - by Budda

  On my web-page I have PlaceHolder, not controls are loaded into it. <asp:PlaceHolder ID="PlaceHolderStatMain" runat="server"> </asp:PlaceHolder> I am looking the ViewState generated for the page, it is the following: <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/wEPDwUJLTg1NDkyNTUzD2QWAgIDD2QWAgIND2QWAmYPZBYCAgEPZBYCZg9kFgJmD2QWBmYPFQEYL3N0YXRfc3RhZGl1bS9sZWFndWVfV0VGZAIBDxUBGC9zdGF0X3N0YWRpdW0vbGVhZ3VlX0VFRmQCAg8VARgvc3RhdF9zdGFkaXVtL2xlYWd1ZV9GQ1VkZEuSBUr5LFL6WfCehNBJgjrq0GzwWCWN2qlU70V7LAAb" /> When I set EnableViewState to false: <asp:PlaceHolder ID="PlaceHolderStatMain" runat="server" EnableViewState="false"> </asp:PlaceHolder> The viewstate content was decreased significantly: <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/wEPDwUJLTg1NDkyNTUzZGTTn8Y28VwmpE/K7yPPkLFvhrqMdU8THijFW/BMFzk0tQ==" /> Question: how to remove 'useless' viewstate content without disabling viewstate for placeholder himself (I would like other control loaded into placeholder to has viewstate)? Is it possible at all? Any thought are welcome! P.S. I am using ASP.NET 4.0

• Sandcastle setup - Navigation to webpage was canceled.

  - by Prof Plum

  I am try to use Sandcastle Help File Builder, but can't quite get it to work. Here is what I have done: 1) installed the program; works like normal 2) enabled xml in the project I want documentation for that gets generated in the /bin 3) created a new sandcastle help file project 4) added the C# project as (its a WCF service in case that matters) a documentation service 5) ran the "build" to generate the help file 6) went to "documentation"/"view help file"/"view help file" in the GUI 7) The file opens and contains the appopriate "folders", but every page says "Navigation to the webpage was canceled" I have seen the xml file in the /bin and it contains all of my /// comments, so why are they not showing up in the help file? Any ideas?

• Why .NET Boolean has TrueLiteral and TrueString?

  - by user309937

  Why in Boolean type there are two fields with the same value? internal const int True = 1; internal const int False = 0; internal const string TrueLiteral = "True"; internal const string FalseLiteral = "False"; and public static readonly string TrueString; public static readonly string FalseString; static Boolean() { TrueString = "True"; FalseString = "False"; } in reflector generated code, methods don't use those strings but: public string ToString(IFormatProvider provider) { if (!this) { return "False"; } return "True"; } would't it be better to use those const values?

• In Drupal, how to change the values passed to Pathauto?

  - by Vinicius Pinto

  I have Pathauto configured to generate an alias based on the title of a node, for a specific content type. The problem is that I want to make small changes in this title before Pathauto uses it to generate the alias. The first comment in this post suggests the use of hook_token_values, but I couldn't really understand how to use it, even after reading the docs. In my tests, when I implement this hook, the alias generated is always "array", which means I'm missing something. Any help? Thanks.

• Is testability alone justification for dependency injection?

  - by fearofawhackplanet

  The advantages of DI, as far as I am aware, are: Reduced Dependencies More Reusable Code More Testable Code More Readable Code Say I have a repository, OrderRepository, which acts as a repository for an Order object generated through a Linq to Sql dbml. I can't make my orders repository generic as it performs mapping between the Linq Order entity and my own Order POCO domain class. Since the OrderRepository by necessity is dependent on a specific Linq to Sql DataContext, parameter passing of the DataContext can't really be said to make the code reuseable or reduce dependencies in any meaningful way. It also makes the code harder to read, as to instantiate the repository I now need to write new OrdersRepository(new MyLinqDataContext()) which additionally is contrary to the main purpose of the repository, that being to abstract/hide the existence of the DataContext from consuming code. So in general I think this would be a pretty horrible design, but it would give the benefit of facilitating unit testing. Is this enough justification? Or is there a third way? I'd be very interested in hearing opinions.

• Returning the value of an identity column during/after SQL INSERT command

  - by Adam Kane

  Using VS 2010, with ASP.NET, and .NET 3.0, and C#... When I use a System.Web.UI.WebControls.SqlDataSource and call its Insert() method to insert a new row, and that table has an identity column, I'd like my method to return the value of that column. For example, in my SQL 2005 table, I've got: Customer.Id Customer.FirstName Customer.LastName Where Customer.Id is an identity colum. When I call my method InsertNewCustomerRecord( "John", "Smith" ), I'd like to be able to return the Customer.Id that gets automatically generated in the database. Sorry for such a roughly posed question. Let me know if I can add better detail. Thanks.

• Simple File-based Record Storage with Fast Text Searching for Compact Framework and Silverlight

  - by Eric Farr

  I have a single table with lots of records ( 100k) that I need to be able to index and search on several text fields. The easiest searches will have the first part of the string specified (eg, LIKE 'ABC%' in SQL). The tougher searches will need to search for any substring within the text fields (eg, LIKE '%ABC%' in SQL). I need to run on the Compact Framework. SQL Compact is a memory hog and overkill for my one table. Besides, I'd like to be able to run on Silverlight 4 eventually. The file and indexes can be generated on the full .NET Framework and I only need read capability on the Compact Framework. My records are not especially large and can be expressed in fix length format. I'm looking for some existing code or libraries to avoid having to write a file-based BTree implementation from scratch.

• Any Way to Further Customize Embedded Google Calendar?

  - by user117737

  I'd like to embed a few Google Calendars for my client's web site. The "Google Embeddable Calendar Helper" provides very few customization options. Updating the hex code for the background color in the generated source only works if you pick one of the ~70 standard Google Calendar bg colors. (I can tweak the "border" selector because at least it's in an actual statement.) A "view-source" on the rendered page shows a CSS file loaded from the iframe, but I obviously can't change anything in there. And I assume I can't force an override of selectors with my own CSS file because I have no way of "injecting" it into the iframe. Does anyone know of a (non-API) way of tweaking the colors, fonts, and other CSS thingies in an embedded Google Calendar? Thanks in advance...

• Detect aborted connection during ASIO request

  - by Tim Sylvester

  Is there an established way to determine whether the other end of a TCP connection is closed in the asio framework without sending any data? Using Boost.asio for a server process, if the client times out or otherwise disconnects before the server has responded to a request, the server doesn't find this out until it has finished the request and generated a response to send, when the send immediately generates a connection-aborted error. For some long-running requests, this can lead to clients canceling and retrying over and over, piling up many instances of the same request running in parallel, making them take even longer and "snowballing" into an avalanche that makes the server unusable. Essentially hitting F5 over and over is a denial-of-service attack. Unfortunately I can't start sending a response until the request is complete, so "streaming" the result out is not an option, I need to be able to check at key points during the request processing and stop that processing if the client has given up.

• How to preserve struct member identifiers when compiling to LLVM IR with Clang?

  - by smokris

  Say I have the following C structure definition: struct stringStructure { char *stringVariable; }; For the above, Clang produces the following LLVM IR: %struct.stringStructure = type { i8* } ...which includes everything in my definition except the variable identifier stringVariable. I'd like to find some way to export the identifier into the generated LLVM IR, so that I can refer to it by name from my application (which uses the LLVM C++ API). I've tried adding the annotate attribute, as follows: char *stringVariable __attribute__((annotate("stringVariable"))); ...but the annotation doesn't seem to make it through (the structure is still just defined as type { i8* }). Any ideas?

• Virtual StringTree's hint windows are left out on the screen

  - by Edwin

  Hi, See this screenshot, in the middle it's the small hint windows that are generated by a TVirtualStringTree control and were left out on the screen, these hint windows will remain there until the application exits. the problem happens when the treeview's hint is shown and the mouse leaves quickly to the window next to it. Any idea about how to avoid this or how to clear those un-erased hint windows if it's difficult to avid this? Few days ago I asked a similar question, while the hint windows in the screenshots look the same, the are not the same problem. That problem, the hint text never shows and only that kind of uncompleted hint windows are shown; This problem, the hint text shows but the hint windows are not completely erased in a case (as I described above). Hope it's clear.

• Implement keyboard control in JavaScript Grid

  - by Vanco

  I finished building a JavaScript grid control, end everything works fine. Paging, button navigation, column sorting, etc. The cells in the grid are DIVs which are generated using Mootools 1.2.4 (which is heavily used throughout the control). I want to implement keyboard control for the grid, both for paging (page up/page down) and for moving with arrow keys inside the rows/cells of the grid. I think that I have to attach an event handler on each cell of the grid and detect what key is being pressed in order to take an appropriate action. But, I can't set the focus on the cells. What am I missing? How do I do this? Any help is appreciated.

• How should I compensate for a bad WSDL?

  - by Brabster

  I've come across several examples of SOAP-based web services where automated tooling fails to build a client that works. Investigating these examples leads me to believe that the WSDL the service uses to describe itself doesn't quite match the service that's being provided. Maybe a wrong type somewhere, a different data structure - something. I'm unsure what the most appropriate response is - if we assume that the obvious one (get the provider to fix their stuff) isn't available. Some options I can think of: Make a fixed WSDL? Hack the generated code? Any other options? No good options? What good experiences have people had? What works in a real environment? Thanks

• Entity Framework associations killing performance

  - by Chris

  Here is the performance test i am looking at. I have 8 different entities that are table per type. Some of the entities contain over 100 thousand rows. This particular application does several recursive calculations on the client so I think it may be best to preload the data instead of lazy loading. If there are no associations I can load the entire database in about 3 seconds. As I add associations in any way the performance starts to drastically decline. I am loading all the data the same way (just calling toList() on the entity attached to the context). I ran the test with edmx generated classes and self tracking entities and had similar results. I am sure if I were to try and deal with the associations myself, similar to how I would in a dataset, the performance problem would go away. On the other hand I am pretty sure this is not how the entity framework was intended to being used. Any thoughts or ideas?

• How to handle concurrency control in ASP.NET Dynamic Data?

  - by Andrew

  I've been quite impressed with dynamic data and how easy and quick it is to get a simple site up and running. I'm planning on using it for a simple internal HR admin site for registering people's skills/degrees/etc. I've been watching the intro videos at www.asp.net/dynamicdata and one thing they never mention is how to handle concurrency control. It seems that DD does not handle it right out of the box (unless there is some setting I haven't seen) as I manually generated a change conflict exception and the app failed without any user friendly message. Anybody know if DD handles it out of the box? Or do you have to somehow build it into the site?

• cakephp filter index pages according to foreign keys

  - by Marki

  Hi there, I'm pretty new to CakePHP and was missing a crucial feature not generated as scaffold: filtering. What do I have to do to provide dropdowns or multi-selects on the index pages for each field that is a (foreign) key, thereby allowing to filter the table ("OR" inside multi-select, "AND" between different multi-selects, if any)? From what my websearch has shown me there are many more people trying to accomplish the same thing, although I couldn't find anything that would work for me because either they have text fields and do wildcard filtering, or the plugins they propose only work for 1.2 whereas i now started with 1.3 etc. etc. Can someone alleviate the confusion and maybe present some working code or direct me to the definitive guide[tm] where this matter has been solved? Thx

• How to set response header in JAX-RS so that user sees download popup for Excel?

  - by masato-san

  I wrote code that generate Excel file using REST JAX-RS and I confirmed that the generated Excel file is in GlassFish server directory. But my goal is when user click on the button (which generate Excel .xls), I want download popup to show up asking user whether to save or open the .xls file just like any other web services doing for downloading any type of files. According to my search, the step is: generate Excel .xls (DONE) write the excel to stream in JAX-RS file, set response header to something like, String fileName = "Blah_Report.xls"; response.setHeader("Content-Disposition", "attachment; filename=" + fileName); My question is I'm doing all of this in JAX-RS file and I don't have HttpServletResponse object available. According to the answer from Add Response Header to JAX-RS Webservice He says: You can inject a reference to the actual HttpServletResponse via the @Context annotation in your webservice and use addHeader() etc. to add your header. I can't really figure what exactly that means without sample code..

• how to draw a line between two labels in a panel where labels are added during runtime

  - by vybhav

  A panel contains two labels which are generated by mouse clicks on the panel. I want to connect these two labels by drawing a line between them probably by dragging the mouse pointer from one label to another. There are two events here - one is clicking on the panel to generate the labels and the second is connecting these two labels (mouse pressed, mouse dragged and mouse released events). Both these event need to call the repaint() method but for different purposes. But there can be only one paint() method. The problem is when I connect these two labels, the line comes up but the rest of the components on the panel disappear.
