• How to usedo a project-wide sweep for "Remove redundant catch" using Resharper?

  - by David McClelland

  I am dealing with a large old codebase that has a lot of these: try { ... } catch { throw; } Resharper helpfully marks these and offers the option to "Remove redundant catch", but I don't like having to go through one-by-one, I would like to wipe them out all at once. Is there a way to do that with Resharper, possibly by integrating it in with "Code cleanup"?

• Unit testing MVC.net Redirection

  - by Dan

  How do I Unit Test a MVC redirection? public ActionResult Create(Product product) { _productTask.Save(product); return RedirectToAction("Success"); } public ActionResult Success() { return View(); } Is Ayende's approach still the best way to go, with preview 5: public static void RenderView(this Controller self, string action) { typeof(Controller).GetMethod("RenderView").Invoke(self,new object[] { action} ); } Seems odd to have to do this, especially as the MVC team have said they are writing the framework to be testable.

• Why does firefox round-trip to the server to determine whether my files are modifed?

  - by erikkallen

  I have some static content on my web site that I have set up caching for (using Asp.NET MVC). According to Firebug, the first time I open the page, Firefox sends this request: GET /CoreContent/Core.css?asm=0.7.3614.34951 Host: 127.0.0.1:3916 User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.1.5) Gecko/20091102 Firefox/3.5.5 (.NET CLR 3.5.30729) Accept: text/css,*/*;q=0.1 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 300 Connection: keep-alive Referer: http://127.0.0.1:3916/Edit/1/101 Cookie: .ASPXAUTH=52312E5A802C1A079E2BA29AA2BFBC5A38058977B84452D62ED52855D4164659B4307661EC73A307BFFB2ED3871C67CB3A9AAFDB3A75A99AC0A21C63A6AADE9A11A7138C672E75125D9FF3EFFBD9BF62 Pragma: no-cache Cache-Control: no-cache Which my server replies to with this: Server: ASP.NET Development Server/9.0.0.0 Date: Mon, 23 Nov 2009 18:44:41 GMT X-AspNet-Version: 2.0.50727 X-AspNetMvc-Version: 1.0 Cache-Control: public, max-age=31535671 Expires: Tue, 23 Nov 2010 18:39:12 GMT Last-Modified: Mon, 23 Nov 2009 18:39:12 GMT Vary: * Content-Type: text/css Content-Length: 15006 Connection: Close So far, so good. However, if I refresh Firefox (not a cache-clearing refresh, just a normal one), during that refresh cycle Firefox will once again go to the server with this request: GET /CoreContent/Core.css?asm=0.7.3614.34951 Host: 127.0.0.1:3916 User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.1.5) Gecko/20091102 Firefox/3.5.5 (.NET CLR 3.5.30729) Accept: text/css,*/*;q=0.1 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 300 Connection: keep-alive Referer: http://127.0.0.1:3916/Edit/1/101 Cookie: .ASPXAUTH=52312E5A802C1A079E2BA29AA2BFBC5A38058977B84452D62ED52855D4164659B4307661EC73A307BFFB2ED3871C67CB3A9AAFDB3A75A99AC0A21C63A6AADE9A11A7138C672E75125D9FF3EFFBD9BF62 If-Modified-Since: Mon, 23 Nov 2009 18:39:20 GMT Cache-Control: max-age=0 to which my server responds 304 Not Modified. Why does Firefox issue this second request? In the first response, I said that the cache does not expire for a year (I intend to use query parameters whenever things change). Do I have to add another response header to prevent this extra roundtrip? Edit: It does not matter whether I press refresh, or whether I go to the page again (or a different URL, which references the same external files). Firefox does the same again. Also, I don't claim this to be a bug in FF, I just wonder if there is another header I can set which means "This document will never change, don't bother me again".

• How do you persist a class on PostBack in an ASP.NET 3.5 Web Forms project?

  - by Kyle Noland

  How do I persist an ASP.Net class on PostBack? I've already taken the time to go to the database and fill my object with values when the page loads initially, so how can I save this object in an elegant way on a PostBack? The page that contains the custom object posts back to itself. For what it's worth I'm using C# in an ASP.NET 3.5 Web Forms application.

What's the best way to go about this while maintaining the RESTful philosophy?

• Lisp data security/validation

  - by Wayne Werner

  This is really just a conceptual question for me at this point. In Lisp, programs are data and data are programs. The REPL does exactly that - reads and then evaluates. So how does one go about getting input from the user in a secure way? Obviously it's possible - I mean viaweb - now Yahoo!Stores is pretty secure, so how is it done?

• What (software) usb sniffers are available for windows?

  - by frankster

  Are there any software drivers for windows 7 (64-bit) that can report the data transferred between some application software and a usb device? I have tried snoopy (http://sourceforge.net/projects/usbsnoop/) but I can't get it working. Possibly I would need to go down the route of installing an earlier version of windows. Any other suggestions?

• How do I preserve folds in VIM when cutting and pasting?

  - by eeeeaaii

  In vim, you can create a fold with zf, so if is %, you can neatly fold a delimited block. is there a way to select some text in visual mode and automatically fold that? I've noticed that if I select a closed fold and use dd to delete it, then go somewhere else and use P to paste it, the fold will disappear and the fold will be expanded. I want to cut the folded stuff and paste it and have it paste with the folds still intact and closed.

• Object of type "X" cannot be converted to object of type "X"

  - by Benjol

  (Can't believe this hasn't already been asked, but I can't find a dup) In Visual Studio with lots of projects, when I first open the solution, I sometimes get the warning Object of type "X" cannot be converted to object of type "X". Generally rebuilding seems to make it go away, but does anyone know what this is caused by, and how to avoid it? UPDATE I read somewhere that deleting all your resx files and rebuilding can help. I unthinkingly tried this. Not a good idea...

• Changing background image of a Drupal page based on user's selection...?

  - by Sambo

  Hi I'm trying to give my users the functionality to change what the background image used on a page is. The list of background images will be a small number that won't really change. I thought I could add a few Taxonomy terms...one for each background type...then apply a class to the body tag when the page is viewed. Does this sound feasible and if so how would I go about doing it? Thanks Sam

• If a jQuery function calls itself in its completion callback, is that a recursive danger to the stac

  - by NXT

  Hi, I'm writing a little jQuery component that animates in response to button presses and also should go automatically as well. I was just wondering if this function recursive or not, I can't quite work it out. function animate_next_internal() { $('#sc_thumbnails').animate( { top: '-=106' }, 500, function() { animate_next_internal(); } ); } My actual function is more complicated to allow for stops and starts, this is just a simplified example.

• How to Compute a Database Column in .NET

  - by Michael

  I have a Database named CarsType.accdb there are four fields in the data base Item_Name, Item_Num, Item_Qty, Item_Cost. I am able to get the database to display my data in VisualBasic but I am not sure how to get the total cost to appear in my label (lblTotalCost).

• Attributes don't inherit?

  - by Stebi

  I played with attributes and assumed that they are inherited but it doesn't seem so: type [MyAttribute] TClass1 = class end; TClass2 = class(TClass1) end; TClass2 doesn't have the Attribute "MyAttribute" although it inherits from Class1. Is there any possibility to make an attribute inheritable? Or do I have to go up the class hierarchy and search for attributes?

• How to wrap two unmannaged C++ functions into two managed C# functions?

  - by Gbps

  I've got two unmanaged C++ functions, Compress and Decompress. The arguments and returns go as followed: unsigned char* Compress (unsigned char*,int) unsigned char* Decompress (unsigned char*,int) Where all uchars are arrays of uchars. Could someone please help me lay out a way to convert these into managed C# code using the Byte[] array instead of unsigned char*? Thank you very much!

• Which Java version do you mostly (have to) work with?

  - by ferdystschenko

  While from version 5 on, Java provides many extremely useful features like annotations, enums, generics, etc., 1.4 is still in use in many enterprise projects. So I'm wondering what the chances are that you still have to work with 1.4, thus being forced to go without JPA, EJB3 etc. In your answer, please also state the branch of company you work for. Which are the reasons for not switching to Java 5? Thanks, Armin

• Move 3 rectangles up in their X but keep order of rectangles

  - by Nicolas Martel

  I have 3 rectangles being rendered here. Let's say i wanted to move them all above the line yet keep their order, how would i go about that?

  I'm trying to remove the background image on a page that's being loaded via an iframe within a lightbox effect.
