  • Visual Studio web tests: Can a coded webtest be run through the Web Test Editor run view?

    - by Frank Rosario
    Hello, Full disclosure, I'm new to Visual Studio Web Tests and coding for them. I've written a webtest; coded in VB; it runs great. Our QA engineer wants to use this script for performance testing; but he wants the nice GUI that comes when you build a WebTest with the VS WebTest Editor and run it. Is there a way to run a coded webtest through this view? He wants to be able to view each test as it runs to see which pages are having issues, but within the GUI he's used to. Alternatively, I know I could just code something that writes out to a log file; but before I go with that solution; I just wanted to see if this is possible. Any constructive input is greatly appreciated.

  • ie7 preserve whitespace on dynamically injected text

    - by Rajat
    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <script type="text/javascript"> function init(){ document.getElementById('test2').innerHTML = '1 2'; } </script> <style type="text/css"> #test{ white-space:pre; } #test2{ white-space:pre; } </style> <title></title> </head> <body onload="init();"> <div id="test"> 1 2 </div> <div id="test2"></div> </body> </html> Here is an example page showing my problem. I have two divs. Each has this text '1 2' with white-space. The only difference is that one is injected dynamically and one is in the html itself. If you open the above page in IE7, the text in div test2 doesn't respect white space. How can i get the same behavior for the text that is dynamically injected?? P.S. My doctype is triggering standards mode on IE7.

  • Thread-safe initialization of function-local static const objects

    - by sbi
    This question made me question a practice I had been following for years. For thread-safe initialization of function-local static const objects I protect the actual construction of the object, but not the initialization of the function-local reference referring to it. Something like this: namspace { const some_type& create_const_thingy() { lock my_lock(some_mutex); static const some_type the_const_thingy; return the_const_thingy; } } void use_const_thingy() { static const some_type& the_const_thingy = create_const_thingy(); // use the_const_thingy } The idea is that locking takes time, and if the reference is overwritten by several threads, it won't matter. I'd be interested if this is safe enough in practice? safe according to The Rules? (I know, the current standard doesn't even know what "concurrency" is, but what about trampling over an already initialized reference? And do other standards, like POSIX, have something to say that's relevant to this?) For the inquiring minds: Many such function-local static const objects I used are maps which are initialized from const arrays upon first use and used for lookup. For example, I have a few XML parsers where tag name strings are mapped to enum values, so I could later switch over the tags enum values.

  • C++ enumerations and compiler dependency

    - by dougie
    I currently have code with an enum where one value is set and the rest are left to be set by the compiler using the previous value +1, or so I hope. Is this functionality within an enumerated type compiler dependant, an example is below to clarify. enum FUNC_ERROR_CODE { FUNC_SUCCESS, FUNC_ERROR_1 = 24, FUNC_ERROR_2, FUNC_ERROR_3 } Is it safe to assume that FUNC_ERROR_2 will have the value 25 and FUNC_ERROR_3 will have the value 26, regardless of compliler used. I'm coding this so as a function can return an integer value, 0 is always success and any other value can signify failure.

  • How to communicate/share a session between pages over HTTP and HTTPS

    - by spirytus
    What is common practice for coding web applications where part of the site has to be secured (e.g. checkout section) and part not necessarily, let's say homepage? As far as I know sharing sessions in between HTTP and HTTPS parts of the site is not easily possible (or is it?). What would be common approach if I wanted to display on HTTP page like homepage, shopping cart data (items) that users ordered on HTTPS pages? How those two parts of the site would communicate if necessary? Also isn't it security flaw in popular shopping carts as it seems that many of these have only checkout pages secured (SSL) and the rest not? I'm using PHP if it makes any difference.

  • AJAX vs ActiveX/Flash for browser-based game

    - by iconiK
    I have been following the usage of JavaScript for the past few years, and with the release of extremely fast scripting engines (V8, SquirrelFish Extrene, TraceMonkey, etc.) the possibilities of JavaScript have increased dramatically. However, the usage share of Internet Explorer coupled with it's total lack of support for recent standards makes me want to drop a bomb on Microsoft's HQ, as it creates a huge amount of problems for any website. The game will need to be pretty dynamic client-side, with animations and other eye-candy things, but not a full-blown game like those that run directly in the OS using DirectX or OpenGL. However, this might be a little stretch for JavaScript and will certainly feel extremely slow in Internet Explorer (given that the current IE engine can be hundreds of times slower than SFX; gotta see what IE9 will bring), would it be better to just do the whole thing in Flash? I know this means requiring the plug-in AND I have no experience whatsoever with Flash (other than browsing YouTube :P). It also means I can't just output directly from PHP, I would have to use XML or some other format to pass data to it (JSON is directly integrated in JS and PHP can deal with it easily). Another idea would be to provide an alternative interface just for IE, though I don't know how (ActiveX maybe? or with Flash, then why not just provide it to all browsers) or totally not supporting it and requiring the use of other browsers, although this is plain stupid from a business perspective. So here am I, wondering what approach to take and thus asking for your advice. How should I build the client-side? AJAX in all browsers, Flash in all browsers or a mix (AJAX for "modern" browsers and something else for the "grandpa": IE).

  • What should I consider when deploying a new web farm?

    - by tsilb
    My web app has been chugging along just great in Production for years with one App server and one Web server. Now we're moving to a multi-server environment with 2 App and 3 Web servers. I have enough time to make changes before the go-live. As a Developer, what considerations should I take into account from coding, deployment, and architectural/ecosystem management perspectives? Already on my list: Remove tight-coupling between servers Applicable files (i.e. downloadables) stored in IMAGE fields in SQL instead of files on app server Deployment: Take out node out of the farm at a time

  • Emacs & PHP indenting question

    - by Danny
    Hi all, I'm a bit new to using emacs for webdevelopment. I am using php-mode and i am happy with it. There is only one issue i have which causes me a lot of problems because of our company's coding style. When i have a function, e.g.: $instance = new Model('foo', 'bar'); And I want to indent it like this: $instance = new Model( 'foo', 'bar' ); Emacs does the following when i insert a newline before the first argument and indents it like this: $instance = new Model( 'foo', 'bar' ); Can anyone point me in a direction on how i can configure/change this? Thanks in advance

  • Which are your favorite programming language gadgets?

    - by FerranB
    There are some gadgets/features for programming languages that I like a lot because they save a lot of coding or simply because they are magical or nice. Some of my favorites are: C++ increment/decrement operator: my_array[++c]; C++ assign and sum or substract (...): a += b C# yield return: yield return 1; C# foreach: foreach (MyClass x in MyCollection) PLSQL for loop: for c in (select col1, col2 from mytable) PLSQL pipe row: for i in 1..x loop pipe row(i); end loop; Python Array access operator: a[:1] PLSQL ref cursors. Which are yours?

  • HOWTO: Deserialize WCF message using OperationContract

    - by Stefan
    Hi, I succeeded in building a WCF client generated by svcutil.exe from the WSDL. Using the generated client proxy class I can call the web service of an external service supplier. I also succeeded in coding a message inspector, as I need to log both raw XML request and response as full SOAP message to the database. For an emergency szenario I also need to be able to "import" a raw XML response. I found many hints on using XMLSerializer or deserializing WCF messages based on the message contract. But how can I deserialize a raw XML response based on an operation contract? For a first test I use one of the logged raw responses, save it to a file and now try to deserialize it to the response type as generated in the client proxy. Somehow I must succeed in calling DeserializeReply() from class ClientOperation. But how to get there? I happily acced any help as I'm quite new to WCF... TIA, Stefan

  • Chipmunk physics: Velocity question

    - by Johannes Jensen
    I'm making an iPhone game where the main actor is a ball that rolls depending on the device's accelerometer rotation. I haven't started on this part of the coding yet, but I was wondering if you guys had a nice way of solving this: I tried looking a little into chipmunk, and I noticed that bodies have the property v, which is a point containing x and y velocities. I was thinking it'd be a bad idea to just do like: playerBody->v = ccp(accelerometer.x * 5, playerBody->v.y); because it'd just roll up of walls and stuff, is there a better solution to do this?

  • non-copyable objects and value initialization: g++ vs msvc

    - by R Samuel Klatchko
    I'm seeing some different behavior between g++ and msvc around value initializing non-copyable objects. Consider a class that is non-copyable: class noncopyable_base { public: noncopyable_base() {} private: noncopyable_base(const noncopyable_base &); noncopyable_base &operator=(const noncopyable_base &); }; class noncopyable : private noncopyable_base { public: noncopyable() : x_(0) {} noncopyable(int x) : x_(x) {} private: int x_; }; and a template that uses value initialization so that the value will get a known value even when the type is POD: template <class T> void doit() { T t = T(); ... } and trying to use those together: doit<noncopyable>(); This works fine on msvc as of VC++ 9.0 but fails on every version of g++ I tested this with (including version 4.5.0) because the copy constructor is private. Two questions: Which behavior is standards compliant? Any suggestion of how to work around this in gcc (and to be clear, changing that to T t; is not an acceptable solution as this breaks POD types). P.S. I see the same problem with boost::noncopyable.

  • Performance Difference between HttpContext user and Thread user

    - by atrueresistance
    I am wondering what the difference between HttpContext.Current.User.Identity.Name.ToString.ToLower and Thread.CurrentPrincipal.Identity.Name.ToString.ToLower. Both methods grab the username in my asp.net 3.5 web service. I decided to figure out if there was any difference in performance using a little program. Running from full Stop to Start Debugging in every run. Dim st As DateTime = DateAndTime.Now Try 'user = HttpContext.Current.User.Identity.Name.ToString.ToLower user = Thread.CurrentPrincipal.Identity.Name.ToString.ToLower Dim dif As TimeSpan = Now.Subtract(st) Dim break As String = "nothing" Catch ex As Exception user = "Undefined" End Try I set a breakpoint on break to read the value of dif. The results were the same for both methods. dif.Milliseconds 0 Integer dif.Ticks 0 Long Using a longer duration, loop 5,000 times results in these figures. Thread Method run 1 dif.Milliseconds 125 Integer dif.Ticks 1250000 Long run 2 dif.Milliseconds 0 Integer dif.Ticks 0 Long run 3 dif.Milliseconds 0 Integer dif.Ticks 0 Long HttpContext Method run 1 dif.Milliseconds 15 Integer dif.Ticks 156250 Long run 2 dif.Milliseconds 156 Integer dif.Ticks 1562500 Long run 3 dif.Milliseconds 0 Integer dif.Ticks 0 Long So I guess what is more prefered, or more compliant with webservice standards? If there is some type of a performance advantage, I can't really tell. Which one scales to larger environments easier?

  • Flex: Would a computational engine for a Connect-4 type game be too slow?

    - by Robusto
    OK, I was just fooling around in my spare time and have made this cool interface and game-playing code for a Connect-4 type game, written in Flex and playable by 2 human players in Flash. It accurately detects wins, etc. I'm smart enough to know that I've done the easy part. Before I dig into an AI for game play, I wanted to ask if this is the kind of thing that can really be handled computationally by a Flash plugin. It seems to me that for every turn up until the end there are 8 possible moves, 8 responses to each move, etc. So wouldn't a perfect engine have to be able to potentially see 8^8 moves (over 16 million), and a fairly good engine see up to a million? I don't know game coding so this is new to me. What's a reasonable move horizon for such a game to be able to see?

  • jQuery AJAX converting variable string to html styled text

    - by sadmicrowave
    I've got an AJAX transmission of a variable string in my primary coding language (Visual FoxPro 9) that looks like this: AjaxResponse = CREATEOBJECT("Custom") lcMessage = "<li class='hello'>Hello</li>" AjaxResponse.AddProperty("Reply", lcMessage) Response.ContentType = "text/html" Response.Write(AjaxResponse.Reply) While using the jQuery function .ajax() I've created a success: function that looks like this: $.ajax({ url: 'index?Proc=GetUuserHistory', dataType: "html", success: function(data){ $("div#history-text").text(data); }; }); My problem is that the text inserting into 'div#history-text' is unformatted and contains the li tags still. I've tried substituting the .text for .prepend, .append, and .html with no luck...is there a way to convert this string back to html format after its been received using Ajax?

    Hello, I am new to this, I just reading about how I should not edit code on the live production server. I don't know anything about source control or SVN. I would like to start coding on a test server then once everything is confirmed working, I want to send all the files over to the production server. How should I go about this? I am on mac os x and was looking into apps like http://versionsapp.com/ but I am not sure if this is the right solution. What do you suggest?

  • CSS filters - sometimes working, sometimes not?

    - by a2h
    I'm on the verge of pulling my hair out over this. Here I have a block of perfectly functioning CSS: #admin .block.mode.off { opacity: 0.25; -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(opacity=25)"; filter: progid:DXImageTransform.Microsoft.Alpha(opacity=25); } Meanwhile... Internet Explorer 8 couldn't care less about my filter declarations here: #admin .drop .tabs { margin-bottom: 12px; } #admin .drop .tab { margin-right: 4px; } #admin .drop .tab.off { cursor: pointer; opacity: 0.5; -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(opacity=50)"; filter: progid:DXImageTransform.Microsoft.Alpha(opacity=50); } #admin .drop .tab.off:hover { text-shadow: 0px 0px 4px #fff; } #admin .drop .tab.on { cursor: default; text-shadow: 0px 0px 4px #fff; -ms-filter: "progid:DXImageTransform.Microsoft.Glow(color=#fff, strength=4)"; filter: progid:DXImageTransform.Microsoft.Glow(color=#fff, strength=4); } My document shows in IE8 Standards, and I am assuming the developer tools are a load of tuna, because the functioning block shows up in its CSS tab as: filter: progid:DXImageTransform.Microsoft.Alpha(opacity=25); opacity: 0.25 Does anyone have any ideas?

  • simile exhibit ie7 bug

    - by two7s_clash
    'm using to Exhibit to, pretty simply, display some data on historical events and book publication dates: http://f1shw1ck.com/timeline3/exhibit.html Everything works fine, and I have been able to get the timeline running as wanted, until I try to take control of the timeline with a timelineConfig script. After I add this, my timeline continues to work as expected on all browsers, except for IE. Curiously enough, band 0 initializes and is rendered correctly, but band 1 shows no events and does not sync to the band above. But it is picking up the width: 10%", intervalUnit: Timeline.DateTime.DECADE, intervalPixels: 60 specifications, as they are rendered correctly. Since everything works until I call ex:configuration="timelineConfig", since everything works in the other browsers, and since everything almost works in IE, up to the event painting, I have to imagine this is a javascript coding error on my part, but I just can't see it. All I get in my console is Failed to create view View As Timeline." Incidentally, having or not having the gotoYear function seemingly does nothing to change... Thanks for any tips.

  • Inconsistent height of text input elements between Firefox and WebKit

    - by Trevor Burnham
    OK, I realize that this is something of an eternal question, but here goes: I've got a single text input, <input type="text" name="whatever" /> and I've specified its font-family, font-size and padding. Yet, even on the same machine (my Mac, let's say), the input has a different height in Firefox (3.6) than it does in Chrome or Safari. Specifically, Firefox adds a little bit more padding below the text. And no, specifying height in pixels doesn't achieve consistency either. Is there any way to achieve text input height consistency across Gecko- and WebKit-based browsers (let alone IE and Opera) without resorting to JavaScript? And if I must use JavaScript, has someone already devised a jQuery plugin or something to easily do this? Update: Here's what not to do. The jqTransform plugin lets you skin form elements and promises that they'll look the same across browsers. Here's how the demo input looks in Chrome 5 on my Mac: and here's how the same input looks in Firefox 3.6.4: I haven't altered these screenshots in any way, just cropped them. Now, my first reaction is, "Ugh, I don't want to support Firefox." But there are currently more Firefox users than Safari and Chrome users combined, so that's not an option. Someone, please help! I just want my forms to look the same across modern, standards-compliant browsers! And by "look the same," I'm not talking about the outline on selection or anything like that; I'm just talking about having the same width, height, and text placement!

  • Office Interop addins installer?

    - by jimbojw
    I have three C# Solutions in Visual Stuido 2008, one each for Word, Excel and PowerPoint using interop to hook various events. In each Solution, I have exactly one class, the one created by default when using File - New - Project - Visual C# - Office - 2007. Now that I have my addins working properly, it's time to create an installer. I understand that I may also have to distribute the PIAs. I would like my installer to register itself such that it can be uninstalled via the normal Add/Remove Programs mechanism. My organization is somewhat standardized around WiX for creating installers, but I'm open to any suggestions. How do I produce an MSI or EXE capable of installing my addins? GUI/wizard for the installer is not necessary. I'm happy to RTFM - so far all the tutorials I've found only explain how to create the project and do some of the coding. Maybe I'm using the wrong search terms? Thanks in advance for any help!

  • Dynamically determining table name given field name in SQL server

    - by Salman A
    Strange situation: I am trying to remove some hard coding from my code. There is a situation where I have a field, lets say "CityID", and using this information, I want to find out which table contains a primary key called CityID. Logically, you'd say that it's probably a table called "City" but it's not... that table is called "Cities". There are some other inconsistencies in database naming hence I can never be sure if removing the string "ID" and finding out the plural will be sufficient. Note: Once I figure out that CityID refers to a table called Cities, I will perform a join to replace CityID with city name on the fly. I will appreciate if someonw can also tell me how to find out the first varchar field in a table given its name.

  • int considered harmful?

    - by Chris Becke
    Working on code meant to be portable between Win32 and Win64 and Cocoa, I am really struggling to get to grips with what the @#$% the various standards committees involved over the past decades were thinking when they first came up with, and then perpetuated, the crime against humanity that is the C native typeset - char, short, int and long. On the one hand, as a old-school c++ programmer, there are few statements that were as elegant and/or as simple as for(int i=0; i<some_max; i++) but now, it seems that, in the general case, this code can never be correct. Oh sure, given a particular version of MSVC or GCC, with specific targets, the size of 'int' can be safely assumed. But, in the case of writing very generic c/c++ code that might one day be used on 16 bit hardware, or 128, or just be exposed to a particularly weirdly setup 32/64 bit compiler, how does use int in c++ code in a way that the resulting program would have predictable behavior in any and all possible c++ compilers that implemented c++ according to spec. To resolve these unpredictabilities, C99 and C++98 introduced size_t, uintptr_t, ptrdiff_t, int8_t, int16_t, int32_t, int16_t and so on. Which leaves me thinking that a raw int, anywhere in pure c++ code, should really be considered harmful, as there is some (completely c++xx conforming) compiler, thats going to produce an unexpected or incorrect result with it. (and probably be a attack vector as well)

  • How extensible should code actually be?

    - by griegs
    I've just started a new job and one of the things my new boss talked to me about was code longevity. I've always coded to make my code infinently extensible and adaptable. I figured that if someone was going to change my code in the future then it should be easy to do. But I never really had a clear idea on how far into the future that should be. So my new boss told me not to bother coding for anything more that 3 years into the future and his reasoning was that technology changes, programs expire etc. At first I was kinda taken aback and thought he was a whack job but the longer I think about it the more I'm warming to the concept. Does anyone else have an opinion on how far into the future you should code to?

  • Finding the best folder for all users on a Windows machine

    - by reallyjoel
    We are making a game which will add a level editor feature soon. We want the user to be able to put levels he's downloaded in a folder and then play it in the game, without any hassle. So, we're looking for a folder that anybody can find, open, write, read, and is multiuser. On Windows Vista / 7, the folder /Users/Public/ look like a great candidate. However, It's not listed in the .net enum System.Environment.SpecialFolder. I have went through them all, and checked what they yield on different Windows versions, and none live up to my requirements. I did find Environment.SpecialFolder.CommonApplicationData, that kinda works, but that folder is hidden (C:\ProgramData) and I assume most users don't display hidden folders. As it stands now, it looks like we'll have to settle for the personal documents folder, but we'd really like a multi user folder? Anyone have any tips? (Hard coding c:\Users\Public\ is out of the question, it will only work on english systems)
