• PHP - Looking for an HTML Generator/Manager

  - by John Himmelman

  I'm trying to find a tool that I can use to generate markup programatically (non-irl word). Here is an example of what I'm trying to accomplish in pseudo-code... $htmlDoc = new HTML_Document(); $htmlDoc->setTitle('Cool Title'); $htmlDoc->addJs('some_js_file.js'); $htmlDoc->addStylesheet('some_css_file.css'); $divElement = new HTML_Element_Div(); $htmlDoc->append('body', $divElement); $output = $htmlDoc->generate(); What is the best tool for this?

• can I read exactly one UDP packet off a socket?

  - by Brian Palmer

  Using UNIX socket APIs on Linux, is there any way to guarantee that I read one UDP packet, and only one UDP packet? I'm currently reading packets off a non-blocking socket using recvmsg, with a buffer size a little larger than the MTU of our internal network. This should ensure that I can always receive the full UDP packet, but I'm not sure I can guarantee that I'll never receive more than one packet per recvmsg call, if the packets are small. The recvmsg man pages reference the MSG_WAITALL option, which attempts to wait until the buffer is filled. We're not using this, so does that imply that recvmsg will always return after one datagram is read? Is there any way to guarantee this? Ideally I'd like a cross-UNIX solution, but if that doesn't exist is there something Linux specific?

• .Net with single .exe without .NET Framework installation

  - by user156144

  I wrote my simple desktop program in C#. I am reluctant to distribute it on the internet because i am not sure if users will go through pain of installing the .Net Framework. My target users are non-tech savvy users. I am very familiar with MFC and I probably can write this program in MFC in a month. MFC is nice because I don't have to worry about distributing other components. It will be one nice single executable. So my real question is this: Is it possible to write .Net app without worrying about distributing .Net Framework? Update I found another solution: If you are using Innosetup, there is a script that installs .net framework. http://www.codeproject.com/KB/install/dotnetfx_innosetup_instal.aspx

• Does salesforce.com have a timezone field that is DST aware?

  - by vfilby

  I am mailing out reminders to potential customers and the time is getting converted to our servers timezone EST (I think it is currently using EDT though as appropriate). I need to store the timezone for the potential customer and translate the time into their current timezone. I can store the offset but I am worried about daylight savings time. I can always store a non-DST offset but that causes issues when the signup appointment is scheduled before DST but occurs after DST. Ideally I would like to store a timezone and have salesforce translate the datetime to that timezone accounting for DST if necessary. How can I do this?

• How do I load content with ujs, jquery and rails?

  - by Joseph Silvashy

  I'm trying to figure out the best way to insert content into a light box using rails UJS. I have a link that looks like this: <%= link_to "login", login_path, :remote => true %> Which produces html as such: <a data-remote="true" href="/login">login</a> So this all works great, and I've created the view file: user_sessions/new.js.erb which also loads just fine, but my question what is the preferred method of inserting appending the html into the page? Like I already have the login form on the non-js page, so can't I just load that partial into the page? Any ideas would be very welcomed.

• Recommendations for a google finance-like interactive chart control

  - by Chris Farmer

  I need some sort of interactive chart control for my .NET-based web app. I have some wide XY charts, and the user should be able to interactively scroll and zoom into a specific window on the x axis. Something that acts similar to the google finance control would be nice, but without the need for the date labels or the news event annotations. Also, I'd prefer to avoid Flash, if that's even possible. Can someone please give some recommendations of something that might come close? EDIT: the "real" google timeline visualization is for date-based data. I just have numeric data. I tried to use that control for non-date data, but it seems to always want to show a date and demands that the first data column actually be a date.

• Anyone up to creating a tomcat based alternative for GAE?

  - by bach

  Hi, If we had the possibility to run GAE app without any code change on our servlet engine that would be great because: in case that google changes their billing policy we can just jump to our own server or in case their current policy doesn't fit our app needs we can do stuff which is not allowed in the GAE, compromising a 1 JVM, 1 DB We don't actually need a distributed system but more of a realtime system with synchronize, true locking mechanisms, other servers/software installed on the server machine, socket interface etc... Such a package should include at least: TomCat (or equivalent) DataNucleus Access Platform (Task Queue service) Any idea if it's easy to get such a thing or if it's already exist somewhere? Thanks

• Learning JavaScript... Should I skip straight to the good stuff (the frameworks)?

  - by Grogs

  I learnt HTML/CSS a good few years back, then PHP a little later. I've recently become interesting in web development again, just started playing with frameworks like Django and RoR. I'm curious as to how much time/effort I should spend learning straight JS before looking at frameworks. I've been reading through a let of articles called Mastering AJAX by Brett McLaughlin which seems quite good, but I'm seeing a lot of stuff (such as cross browser compatibility - even for things like XMLHttpRequest) coming up which look like they would be non-issues if using a framework. So, should I keep reading through these articles and try to build stuff using basic JS, or should I just start looking into jQuery and the like? Also, I've been watching a few videos regarding GWT from Google I/O. I've been learning Java over the last year, built a few medium sized apps in it. I'm wondering if GWT is something that's worth going straight to, along with gQuery?

• Linking to libcrypto for Leopard?

  - by adib

  Hi I am using Mac OS X 10.6 SDK and my deployment target is set to Mac OS 10.5. I'm linking to libcrypto (AquaticPrime requires this) and found out that my app doesn't launch on Leopard. The error is dyld: Library not loaded: /usr/lib/libcrypto.0.9.8.dylib I've tried the following workarounds but none of them work: Linking directly to libcrypto.0.9.7.dylib (the 10.6 SDK refuses to link directly with libcrypto.0.9.7.dylib. Copying the 10.5 SDK's version of libcrypto.0.9.7.dylib to the 10.6 lib directory and try t link with it (this time the link process succeeded but in Leopard the app still tries to lookup the non-existent libcrypto.0.9.8.dylib file and thus won't launch). Copying libcrypto.0.9.7.dylib from a Mac OS X 10.5.8 installation and link with it (the link was successful but the app still looks for libcrypto.0.9.8.dylib). Is there a way to link to this library and still use the 10.6 SDK? Thanks.

• How can I get Hudson to be able to access JUnit?

  - by Bedwyr Humphreys

  I've got Hudson running on TOMCAT, it can build my Netbeans project using the ant build.xml, but it won't run any of my unit tests because of what I assume is a problem with the classpath: package org.junit does not exist [javac] import org.junit.After; [javac] ^ But I've got the junit-4.8.1.jar on the classpath in /etc/environment and I can successfuly run the junit tests from a console using java org.junit.runner.JUnitCore org.junit.tests.AllTests My CLASSPATH is set to /home/bedwyr/junit4.8.1/junit-4.8.1.jar:. Am I going wrong somewhere or is there anything else I need to set? [edit] What I did was to export/include (using the ide) all libraries (including Junit) hudson then reads all it needs from the subversion repo. I then ran into an issue with exposing hudson to the internet, and pretty soon gave up on tomcat on ubuntu server (again, to do with the tomcat security manager) - glassfish is a lot smoother and that's where I am now - apache front end with ajp_proxy to hudson on glassfish.

• What is the most stupid coded solution you have read/improved/witnessed?

  - by Rigo Vides

  And for stupid I mean Illogical, non-effective, complex(the bad way), ugly code style. I will start: We had a requirement there when we needed to hide certain objects given the press of a button. So this framework we were using at the time provided a way to tag objects and retrieve all the objects with a certain tag in a complete iterable collection. So I presented the most logically solution given these conditions to my partner: Me: you know, tag all the objects we needed to hide with the same tag, then call the function to get them all, iterate trough them and make them hidden. Partner: I don't know, that is hardcoding for me... Me: So what do you suggest? 20 mins later... Partner: I don't know... let's put a tag to all the objects to be hidden like this, 1, 2, 3, 4, 5, 6, 7 (and so for each object to be hidden), Then we make a for from 1 to n (where n was the number of objects to hide) and we hide them all there!

• Chrome Extension: How to display tab objects?

  - by Jalleluhah

  I am in the process of designing an extension for Google Chrome that helps to organize tabs (I know, there are many that already exist; that doesn't matter). I wish to open a popup window that will display tabs as objects (i.e., in the same way that it is displayed in the tab bar at the top of the browser). One way of doing this would be to pull various details (ID, Title, URL, etc.) from each tab, create a class and make instantiations of it upon the opening of each tab using these data, but this seems rather convoluted considering that what I want is sitting right there in the tab bar. Is there any simpler way to achieve this? In addition, I have seen several apps that utilize page previews. Is there something in the API that allows direct access to these?

• Is it wrong to get feedback from Stack Overflow on a live system architecture?

  - by hal10001

  I am the technical director at a startup, and I will eventually be tasked with implementing a "real" system architecture when we hire more programmers. Right now our clients are small enough, and it is just me, so documented deployments, source control, unit tests and quality assurance servers are non-existent. Eventually I will need to devise a work-flow and architecture patterns for the majority of the work we will do (e-commerce). If I posted an architecture diagram, and asked for feedback, would that be a misuse of the Stack Overflow system? I don't want to get into that battle of "hey, don't ask us to do your job for you", but the reality is that any programmer who eventually moves into this realm will have to figure it out with feedback from other developers. HighScalability.com is what comes to mind when I think about this sorta thing in terms of the knowledge I need. So if this is not the right kind of forum for that, then any book recommendations or white papers you can recommend would be appreciated.

• Do you have to install the REST starter kit in asp.net to access APIs?

  - by jonhobbs

  Hi, I'm currently trying to access a REST API for the first time using visual web developer 2008 express edition. Every article I have found says you have to install the WCF REST starter kit which is a .msi file, which would suggest that I have to install it on my machine and presumably our server too. My question is this. Is there a non installable version that I can use, e.g. just by dropping DLLs into the Bin directory and then using the classes contained. Or is there more to it than that and am I just getting very confused about how it works? Jon

• Tool(s) to lower the friction of programming against Interfaces in Visual Studio C#?

  - by John

  Hi I am a relatively new user of Visual Studio and I am trying "program against interfaces". I can see that when I create a class I can "Extract Interface" from the Refactor menu but you seem to only get one shot at this. ie. If I add a read only property FullName to my Customer class I would like to be able to right click and update the interface. At the moment I can only create a new interface from the Refactor menu. I want to update the interface I have already created not create new one. So the kind of tool I would be looking for would display check boxes for all valid members of the class with those already in the interface checked. It would also be handy to be able to to create the initial interface file in a different project (in the same solution), and for the tool to keep track of this. Does such a tool / add in / menu item exist (other than Ctrl C / V)? Thanks, John

• NSNumberFormatter customize?

  - by Frederick C. Lee

  I wish to use NSNumberFormatter to merely attached a percent ('%') to the supplied number WITHOUT having it multiplied by 100. The canned kCFNumberFormatterPercentStyle automatically x100 which I don't want. For example, converting 5.0 to 5.0% versus 500%. Using the following: NSNumberFormatter *percentFormatter = [[NSNumberFormatter alloc] init]; [percentFormatter setNumberFormat:@"##0.00%;-##0.00%"]; But 'setNumberFormat' doesn't exist in NSNumberFomatter. I need to use this NSNumberFormatter for my Core-Plot label. How can I customize NSNumberFormat? Ric.

• Why is the modal dialog in MFC actually internally modeless?

  - by pythiyam

  This question arose in my miind after reading this article: http://www.codeproject.com/Articles/3911/The-singular-non-modality-of-MFC-modal-dialogs. He mentions that the modal dialog in MFC is not strictly modal, but implemented as a modeless dialog(internally) with bells and whistles to make it behave as a modal one. Specifically, he says: The MFC command routing mechanism uses a combination of message maps and virtual functions to achieve what it does and a true modal dialog will totally wreck this mechanism because then the modal message loop is controlled outside the scope of the MFC command routing machinery Could anyone elucidate this statement? An example of what would have gone wrong if they had tried to implement a truly modal dialog would greatly clear things up.

• DTO and mapper generation from Domain Objects

  - by Nicolas

  I have plenty of java domain objects that I need to transform to DTOs. Please, don't start with the anti-pattern thing, the Domain Objects are what they are because of a long history, and I can't modify them (or not too much, see below). So, of course, we've passed the age of doing all that manually. I've looked around, and dozer seems the framework of choice for DTO mapping. But... what I'd really like is this: annotate classes and fields that I want in DTO, and run a tool that would generate the DTOs and the mappers. Does that sound too unreasonable? Does such a tool already exist?

• Can I resolve ASP.NET "~" app paths to the website root without a Control being present?

  - by jdk

  I want to Resolve "~/whatever" from inside non-Page contexts such as Global.asax (HttpApplication), HttpModule, HttpHandler, etc. but can only find the Resolution methods specific to Controls (and Page). I think the app should have enough knowledge to be able to map this outside the Page context. No? Or at least it makes sense to me it should be resolvable in other circumstances, wherever the app root is known. Update: The reason being I'm sticking ~ paths in the web.configuration files. Update 2: I'm trying to resolve them to the website root such as Control.Resolve(..) URL does, not to a file system path.

• Minimalistic PHP template engine with caching but not Smarty?

  - by Pekka

  There are loads of questions for "the right" PHP template engine, but none of them is focused on caching. Does anybody know a lightweight, high-quality, PHP 5 based template engine that does the following out of the box: Low-level templating functions (Replacements, loops, and filtering, maybe conditionals) Caching of the parsed results with the possibility to set an individual TTL per item, and of course to force a reload programmatically Extremely easy usage (like Smarty's) Modest in polluting the namespace (the ideal solution would be one class to interact with from the outside application) But not Smarty. I have nothing against, and often use, Smarty, but I am looking for something a bit simpler and leaner. I took a look at Fabien Potencier's Twig that looks very nice and compiles templates into PHP code, but it doesn't do any actual caching beyond that. I need and want a template engine, as I need to completely separate code and presentation in a way that a HTML designer can understand later on, so please no fundamental discussions about whether template engines in PHP make sense. Those discussions are important, but they already exist on SO.

• Methods in super that will be subclassed anyway (Cocoa)

  - by Michael Matheus

  Sorry if this is a repost but I couldn't quite search for it because I can't explain it in a few words. I have a super class with lots of methods but they will always (not all of them) be subclassed. From the super I need to access (read only) those methods. I could either leave the methods in super empty or I could just not type them in super but call them anyway like so [self myMethod] and it will call my subclassed method even if it doesn't exist in super. This works but Xcode gives me an error though. 'superclass' may not respond to '-subclassmethod' What should I do?

• Get the number of calendar weeks between 2 dates in C#

  - by Phil Scholtes

  For the purposes of this question, let's assume the user will be from the US and will use the standard Gregorian calendar. So, a calendar week starts on Sunday and ends on Saturday. What I'm trying to do is determine the number of calendar weeks that exist between two dates. A perfect example of my problem exists in October 2010. Between 10/16 and 10/31 there are 4 calendar weeks. View a picture of October 2010 October 10 - October 16 October 17 - October 23 October 24 - October 30 October 31 - November 6 I'd prefer to stay away from any hardcoded logic like: if (Day == DayOfWeek.Saturday && LastDayOfMonth == 31) { ... } Can anyone think of a logical way to do this?
