• How to generalize view?

  - by MexicanHacker

  Hey guys, I'm in the process of designing a set of views that use the same model in my app, the difference is that some views will differ in Read Only and Modifiable fields. So for example for view A I want to be able to modify A.One but no A.Two properties and for view B I want to have B.One and B.Two as modifiable fields. I was thinking in having a map that will hold this information and iterate both the modifiable and non-modifiable lists in a generic view, but I was thinking that maybe I can get feedback from you guys. What do you think?

• How to use RedirectToAction to redirect to the default action of different controller?

  - by atbebtg

  I am trying to do a RedirectToAction from http://mywebsite/Home/ using the following code: return RedirectToAction("Index","Profile", new { id = formValues["id"] }); The above code will succesfully take me to http://mywebsite/Profile/Index/223224 What do I have to do to make it redirect to http://mywebsite/Profile/223224 Thank you. I figured out how to do this. First I have to add custom route rule: routes.MapRoute("Profile", "Profile/{id}", new { controller = "Profile", action = "Index", id = UrlParameter.Optional }); Then I can do the following: [AcceptVerbs(HttpVerbs.Post)] public RedirectResult Index(FormCollection formValues) { return Redirect("~/Survey/" + formValues["Id"]); }

• When is a program limited by the memory bandwidth?

  - by hanno

  I want to know if a program that I am using and which requires a lot of memory is limited by the memory bandwidth. When do you expect this to happen? Did it ever happen to you in a real life scenario? I found several articles discussing this issue, including http://www.cs.virginia.edu/~mccalpin/papers/bandwidth/node12.html http://www.cs.virginia.edu/~mccalpin/papers/bandwidth/node13.html http://ispass.org/ucas5/session2_3_ibm.pdf The first link is a bit old, but suggests that you need to perform less than about 1-40 floating point operations per floating point variable in order to see this effect (correct me if I'm wrong). How can I measure the memory bandwidth that a given program is using and how do I measure the (peak) bandwidth that my system can offer? I don't want to discuss any complicated cache issues here. I'm only interested in the communication between the CPU and the memory.

• How to write an unit test for WCF behaviors?

  - by katie77

  I am new to unit testing. How do I write a unit test for a method when I am extending a WCF behavior. Since I am not sure of when the class is being instantiated, or I can not change the method signature. In the behavior implementation, I am getting the header and looking up a value in the config. public class IncomingValidator : IDispatchMessageInspector { public object AfterReceiveRequest(ref Message request, IClientChannel channel, InstanceContext instanceContext) { // Grab the header and see if one of the particular values(read from config) is there. } public void BeforeSendReply(ref Message reply, object correlationState) { } }

• A better and faster way for eval?

  - by user1707250

  I want to build my queries dynamically and use the following snippet: --snip-- module.exports = { get : function(req, res, next) { var queryStr = "req.database.table('locations').get(parseInt(req.params.id))"; if (req.params.id) { if (req.fields) { queryStr += '.pick(' + req.fieldsStr + ')'; } console.log(queryStr); eval(queryStr).run(function(result) { console.log(result); res.send(result); }); } else if (!req.params.id) { --snip-- However introducing eval opens up my code to injection (req.fields is filled with url parameters) and I see the response time of my app increase from 7 to 11ms Is there a smarter way to accomplish what I did here? Please advice.

• Python: get windows OS version and architecture

  - by Thorfin

  First of all, I don't think this question is a duplicate of http://stackoverflow.com/questions/2208828/detect-64bit-os-windows-in-python because imho it has not been thoroughly answered. The only approaching answer is: Use sys.getwindowsversion() or the existence of PROGRAMFILES(X86) (if 'PROGRAMFILES(X86)' in os.environ) But: Can we completely rely on the windows environment variable PROGRAMFILES(X86)? I fear that anyone can create it, even if it's not present on the system. How can we use sys.getwindowsversion() to get the architecture? Regarding sys.getwindowsversion(): The link http://docs.python.org/library/sys.html#sys.getwindowsversion leads us to http://msdn.microsoft.com/en-us/library/ms724451%28VS.85%29.aspx but I don't see anything related to the architecture (32bit/64bit). Moreover, the platform element if the returned tuple seems to be independent of the architecture. One last note, I'm using python 2.5. Thanks!

• PHP: "Footer function"?

  - by Ricket

  I have a project. It has a good number of PHP files. Each of these files includes a standard header. They don't include a standard footer. Now I want to do something just before the end of every page. I can go through each page and add the footer code, but I was wondering if there is an easier way (and I think I've seen something like it before, though I might be mistaken). Is there a way to set a "hook" or "trigger" function that will be executed at the end of a page, from the included header PHP script? I'm thinking of something like set_error_handler but to handle a page close event. Or like C's atexit function.

• Why does this PNG file look so poorly when embedded as a resource in a Qt project?

  - by George Edison

  Here is the PNG file and what it looks like in a QWebView when accessed via http://sstatic.net/so/img/logo.png: When accessed via HTTP: <img src="http://sstatic.net/so/img/logo.png" width='250' height='61' /> When accessed via a resource: <img src="qrc:/images/logo.png" width='250' height='61' /> As you can see, the only modification was the src attribute of the image tag... why the drop in quality? Edit: The file is being shrunk via width: and height: in the style attribute, if that makes a difference. I updated the code.

• Understanding a lighttpd.conf file?

  - by AP257

  Hi all, I've been given a lighttpd.conf that someone else wrote and need help working out how to serve it. I'm 90% of the way there but stuck... The index.html page appears, but links and CSS files don't point to the right place. To clarify, the links and CSS files are all pointing to a 'file:///' URL. So styles.css in the HTML header points to file:///html/styles.css, whereas it should be going to http://url.com/styles.css Maybe url.rewrite or url.redirect isn't working properly? server.document-root = "~/html" server.port = 28001 mimetype.assign = ( ".html" => "text/html", ".txt" => "text/plain", ".jpg" => "image/jpeg", ".png" => "image/png" ) url.rewrite = ( "^(.*)/($|\?.*)" => "$1/index.html", "^(.*)/([^.?]+)($|\?.*)$" => "$1/$2.html" ) $HTTP["scheme"] == "http" { url.redirect = ( "^/platform/index.html$" => "/platform", "^/about/company.html$" => "/about/company",, ) }

• How can I simulate a click event via script?

  - by Scott B

  I have a jquery accordion style menu that I'd like to add some shortcut links to across the top. When one of these shortcuts is clicked, it should have the same effect as if the user clicked the corresponding a tag that serves as that panel's header... Here's some code... <div> Application Shortcuts > <a href="" onclick="simulateAclick("generalSettings")>Open General Settings</a> </div> <ul class="menu collapsible"> <li class='header'><a href='#' id="generalSettings">General Settings</a> <ul class='acitem'>...stuff goes here... In the example above, clicking on "Open General Settings" toggles the "acitem" UL's child elements visible. I'd just like to simulate a click on that element, from a link at the top of my app...

• VS2008 is very slow on a specific large C++ solution

  - by VioletRose

  I have a solution with 21 C++ projects and 1 VB.NET project. The IDE responds very slowly when I simply move the carret in a file or try to open the menu. The process seems to take 50% of CPU for each movement. It only happens with this solution and only on my machine. The solution has total of 2380 source and header files, of which 1280 are header files. I tried to remove all connection to the source control (Perforce) but it didn't help. Also, I have Visual Assist installed but even after removing it (uninstall), the same behavior continued. Any idea?

• How do you insert new entries into an Access db table through an ASP.net website?

  - by CGF

  I need to insert new records into an Access database. I'm using Visual Studio 2008 and firstly create a asp.net website. I can connect to the information in Access databse using dataview or gridview and can query a particular entry (ie. Proposal No. -brings up all details linking to that proposal). I can then edit the details of that proposal and this would update the Access Db. What I need to do is to have a form that simply enters new details for a new customer. ie. Enter name [__] Enter Adress[__]. Then for this to update the database. By using the gridview or dataview I am able to view all fields that exist in the table and edit them. Is there a way that I can get a blank gridview/dataview template (which includes all the fields in the table) and fill it out to then update the database? Thanks

• How do I link (dependency) properties in my ViewModel?

  - by mos

  Simplified example: I have an object that models a user. Users have a first name and a last name. The UserViewModel has a dependency property for my Models.User object. In the declaration of the UserView's xaml, I want to bind a couple of TextBlocks to the first and last name properties. What is the correct way to do this? Should I have readonly DependencyProperties for the name fields, and when the dependency property User is set, update them? Can the name fields be regular C# properties instead? Or, should I bind like this: <TextBlock Text="{Binding User.FirstName}" />

• Some websites to learn about MySQL tables and creating databases (The Do's and Don'ts)

  - by redsoxmaniac

  I am venturing on making a website with a database for baseball games for an intramural league. I have made databases before, but this project seems to have many fields that will require at least 3 tables. I want to make the tables correct, so that I can sort and gather information from multiple fields properly ( such as the team table querying total goals scored ). Is there a website where there is a MySQL tutorial on do's and don'ts for making somewhat complex databases? Not intro tutorials, but more around where you get into combining multiple pieces of information correctly. Any source would be helpful, thanks!

• Export Specific Page from MediaWiki

  - by wag2639

  We have an internal document wiki running on MediaWiki (latest stable). Is there a way we can export a specific page for a customer without giving them access to the entire wiki (which is currently behind a PAM-based authentication). Edit1: Sorry for the vagueness, I meant is there a way to syndicate a specific page so that they don't actually have access to the wiki but the content is still available and up-to-date. For example, the page I want them to see http://mysite.com/wiki/page_to_see Can I have it available at http://mysite.com/outsite_wiki

• Writing different structs to a file in C++? [on hold]

  - by user58053

  I need a way to write structures of three different kinds to a binary file, which later has to be searched. (As in, for example, struct A has two fields, an int and a char; struct B has int and a long; I need to output all structures whose int equals the one given from keyboard). I understand how to write structs of the same kind to a file and how to search them, but here I am just lost, best thing I came up with is declaring a struct containing all possibly needed fields and leaving the ones I don't need empty, but it really feels wrong, there HAS to be a better way to do that. I've read about binary files and could not find anything relevant, most examples and tutorials deal with writing one data type. Could anyone point me in the right direction? EDIT: I am looking for what @Jerry_coffin called database mode, and will probably use one of the existing database systems for that, best way to go, probably. Thank you everybody for the suggestions

• Force a page cache of Ajax content

  - by Webnet

  I have a page that is an search where the results are loaded via ajax. It then lists products on a page and you can click to view each product. I'd like to change this page where after you view a product if you click "back" on your browser it'll load the cache instead of forcing the user to search again. How can I achieve this? I currently have.... header('Cache-Control: private, max-age:3600'); header('Expires: '.gmdate('D, d M Y H:i:s \G\M\T', time() + 3600)); and it doesn't load the cache

Am I missing anything?

• why include() don't allow to work setcookie?

  - by Syom

  i need to set cookies in my page, but it returns Warning: Cannot modify header information - headers already sent by (output started at /home1/bsam/public_html/24kadr/index.php:1) in /home1/bsam/public_html/24kadr/basic_login.php on line 35 on line 1 i have include 'basic_login.php'; but even if i remoove include, ir returns the same warning on session_start, or mysql_connect. so i think these all functions use header when calling, but what can i do? at least i need to connect to database, and just after it i need to use setcookie(). so what can i do? thanks

• Using PHP to grab the absolute URL of the script?

  - by Rob

  Basically, I want my script to output its absolute URL, but I don't want to statically program it into the script. For example, if my current URL is http://example.com/script.php I want to be able to store it as a variable, or echo it. i.e. $url = http://example.com/script.php; But if I move the script to a different server/domain, I want it to automatically adjust to that, i.e. $url = http://example2.com/newscript.php; But I have no idea how to go about doing this. Any ideas?

• Compilation failing - no #include - boost

  - by jwoolard

  Hi, I'm trying to compile a third-party library, but g++ is complaining about the following line: typedef boost::shared_ptr<MessageConsumer> MessageConsumerPtr; The strange thing is, there is no #include directive in the file - and it is clearly supposed to be this way; there are about 60 files with the same (or very similar) issues. Clearly if there was an #include directive referencing the relevant boost header this would compile cleanly. My question is: how can I get g++ to somehow automagically find the relevant symbol (in all instances of this issue, it is a namespace that can't be found - usually std:: or boost::) by either automatically processing the relevant header (or some other mechanism). Thanks. Edit My current g++ call looks like: g++ -fPIC -O3 -DUSING_PCH -D_REENTRANT -I/usr/include/boost -I./ -c MessageInterpreter.cpp -o MessageInterpreter.o

• Fancybox2 Inline Content Gallery

  - by beefchimi

  I am trying to create a gallery of inline content with Fancybox 2, and am failing miserably. I checked out some other resources online and they seem to indicate doing this relatively easily, yet, I cannot seem to get it to work. Here is my fiddle: http://jsfiddle.net/beefchimi/jtxHd/2/ Now, I feel like the fiddle is not loading the resources, so thats a problem. But even with the resources this does not work, I get the fancybox error. Resources: http://fancyapps.com/fancybox/source/jquery.fancybox.pack.js?v=2.1.3 http://fancyapps.com/fancybox/source/jquery.fancybox.css?v=2.1.3 Any help would be greatly appreciated. EDIT: So I can't submit my question without including some code, because linking to jsfiddle isn't okay, so, here is my fancybox initialization, which you will also find in the jsfiddle: $(document).ready(function() { $('a.inlinepopup').fancybox({ 'width' : '75%', 'height' : '75%', 'autoScale' : false, 'type' : 'iframe' }); });

• How to allow three optional parameters in the URL by .htaccess?

  - by eij

  I have http://example.com and a PHP routing class that checks if some URL exists. I want to make a new route, which is: http://example.com/foo/bar/123 but as long as I open it, the Apache redirects me to an error page. So I'm using a .htaccess. The code is: RewriteEngine on RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*) /index.php [L] and it works, as long as I use http://example.com/foo, but once I add some other parameters, it redirects me to an error. I'm guessing that the rewrite code is wrong. Is it wrong? If yes, could you suggest me the good one? If no, where the problem could be located?
