• Simulating Ajax failures for QA testing

  - by womp

  Our first ASP.Net MVC/jQuery product is about to go to QA, and we're looking for a way for our QA guys to easily be able to simulate bad Ajax requests (without modifying the application code). A typical integration/UI test plan might be: Load page, click button "DoStuff" "DoStuff" fails Attempt button "DoStuff" again "DoStuff" succeeds Verify application state This is a simple test case - there will be cases with multiple failures and successes interspersed. Aside from "unplug your network cable" I'm looking for an easy way for our guys to simulate intermittent bad server responses. I'm open to any ideas so I won't go into too many details about our application setup or dependencies. How have you handled this?

• Service Layer Pattern - Could we avoid the service layer on a specific case?

  - by lidermin

  Hi, we are trying to implement an application using the Service Layer Pattern cause our application needs to connect to other multiple applications too, and googling on the web, we found this link of a demonstrative graphic for the "right" way of apply the pattern: martinfowler.com - Service Layer Pattern But now we have a question: what if our system needs to implement some business logic, only for our application (like some maintenance data for the system itself) that we don't need to share with other systems. Based on this graphic: As it seems, it will be unnecesary to implement a service layer just for that; it will be more practical to avoid the service layer, and just go from User Interface to the Business Layer (for example). What should be the right way in this case to implement the Service Layer Pattern? What do you suggest us for a scenario like the one I told you? Thanks in advance.

• Identify Executable Creating Network Traffice

  - by jeffspost

  I've got some application on my Windows XP machine that is generating an HTTP request to aaronsw.com every half hour. We've trapped the packets in wireshark, but wireshark doesn't tell what application generated the packets. Is there any utility that looks at network traffic AND tells what executable produced the traffic?

• directx audio video error message in debugmode

  - by clamp

  I have a c#/winforms application that uses directx to play some video and audio. whenever i start my application in debugmode i get this annoying message. i can click "continue" and everything seems to work fine. but i still want to get rid of this message. it does not show up in releasemode. Managed Debugging Assistant 'LoaderLock' has detected a problem in 'C:\pathtoexe.exe'. Additional Information: DLL 'C:\WINDOWS\assembly\GAC\Microsoft.DirectX.AudioVideoPlayback\1.0.2902.0__31bf3856ad364e35\Microsoft.DirectX.AudioVideoPlayback.dll' is attempting managed execution inside OS Loader lock. Do not attempt to run managed code inside a DllMain or image initialization function since doing so can cause the application to hang.

• Performance problem Loading Dataset inside a virtual.

  - by ShaneH

  Host Configuration: HP EliteBook 8530w 4G Ram Win7 Ultimate 64Bit RC SQL Server 2005 64bit Developer Edition Virtual: Windows Virtual PC 1G Ram allocated Integration Services installed Windows XP 64bit Up to date service packs and .Net framework through 3.5 SP1 Sharing the Gigabit network adapter of the Host I have a simple .Net console application which loads a dataset of approximately 37K rows. Running the application on the host executes in approximately 4 seconds. Running inside the virtual takes 729 seconds. The size of the application grows to about 65Mb when the dataset is finished loading, no calculated columns or event handlers are attached. [edit] I changed the virtual to use a loopback adapter to communicate with the host and performance is now on par with running on hardware. Any ideas as to why it would going over the network adapter be almost 200x longer? TraceRt shows that the connection is only one hop. Thanks, Shane Holder

• Can I get information about the IIS7 virtual directory from Application_Start?

  - by Keith

  I have 3 IIS7 virtual directories which point to the same physical directory. Each one has a unique host headers bound to it and each one runs in its own app pool. Ultimately, 3 instances of the same ASP.NET application. In the Application_Start event handler of global.asax I would like to identify which instance of the application is running (to conditionally execute some code). Since the Request object is not available, I cannot interrogate the current URL so I would like to interrogate the binding information of the current virtual directory? Since the host header binding is unique for each site, it would allow me to identify which application instance is starting up. Does anyone know how to do this or have a better suggestion?

• Modular enterprise architecture using MVC and Orchard CMS

  - by MrJD

  I'm making a large scale MVC application using Orchard. And I'm going to be separating my logic into modules. I'm also trying to heavily decouple the application for maximum extensibility and testability. I have a rudimentary understanding of IoC, Repository Pattern, Unit of Work pattern and Service Layer pattern. I've made myself a diagram. I'm wondering if it is correct and if there is anything I have missed regarding an extensible application. Note that each module is a separate project.

• Does Windows 7 have a Kiosk Mode?

  - by Jordan

  I'm writing a Kiosk on a Windows 7 computer. The Kiosk is on a touch screen computer, that will not have a keyboard. The application is a WPF application running the .NET Framework version 3.5. I'm having problems with the progress bar task bar showing up (blinking) at the bottom of the screen. This unfortunately gives the user access to the background operating system. Is there someway to lock a full screen application window into the front of the screen without using it on-top-of-everything mode. Some sort of Kiosk mode, or some tool that was designed for this.

• Permissions required to look up a domain user's group memberships

  - by adrianbanks

  I am writing some code to look up the members of particular domain groups. Does the user that this application runs as need any particular permissions on the domain to get this information? Background: I have already determined that the application needs to be run as a domain user to be able to query information from the domain. I have a list of group names and for each group, I need to look up the members of that group on the domain and get their names/usernames.

• Asp.net cached objects staying in memory

  - by GordonB

  I have a asp.net web forms app that uses System.Web.Caching.Cache to cache xml data from a number of web services for 2 hours. webCacheObj.Remove(dataCacheKey) webCacheObj.Insert(dataCacheKey, dataToCache, Nothing, DateTime.Now.AddHours(2), Nothing) Every 90 minutes a Microsoft Search Server hits a particular (spider) page which calls the code to put the objects into the cache. The issue i have is that over a period of time, the memory usage of the application grows exponentially. Lets say that in a week, the memory usage of the application pool grows to over 1gb. I'm using IIS7 and no application pool recycling is currently enabled.

• Remote script execution on Windows 2003 server - alternatives to PSEXEC

  - by chickeninabiscuit

  We are wanting to deploy our application to our Test server from our Hudson server. I'd like to be able to have hudson copy the application files and start a script that would run locally on our Test server. We can't use psexec because of a cross domain policy. Currently we are doing this manually, by RDPing to the Test server and checking out the code from subversion manually. Are there alternatives to PSExec that can bypass the cross domain policy problem?

• Limiting the number of threads executing a method at a single time.

  - by Steve_

  We have a situation where we want to limit the number of paralell requests our application can make to its application server. We have potentially 100+ background threads running that will want to at some point make a call to the application server but only want 5 threads to be able to call SendMessage() (or whatever the method will be) at any one time. What is the best way of achieving this? I have considered using some sort of gatekeeper object that blocks threads coming into the method until the number of threads executing in it has dropped below the threshold. Would this be a reasonable solution or am I overlooking the fact that this might be dirty/dangerous? We are developing in C#.NET 3.5. Thanks, Steve

• I can't change HTTP request header Content-Type value using jQuery

  - by Matt

  Hi I tried to override HTTP request header content by using jQuery's AJAX function. It looks like this $.ajax({ type : "POST", url : url, data : data, contentType: "application/x-www-form-urlencoded;charset=big5", beforeSend: function(xhr) { xhr.setRequestHeader("Accept-Charset","big5"); xhr.setRequestHeader("Content-Type","application/x-www-form-urlencoded;charset=big5"); }, success: function(rs) { target.html(rs); } }); Content-Type header is default to "application/x-www-form-urlencoded; charset=UTF-8", but it obviously I can't override its value no matter I use 'contentType' or 'beforeSend' approaches. Could anyone adivse me a hint that how do I or can I change the HTTP request's content-type value? thanks a lot. btw, is there any good documentation that I can study JavaScript's XMLHttpRequest's encoding handling?

• I've created a database table using Visual Studio for my C# program. Now what?

  - by Kevin

  Hi! I'm very new to C#, so please forgive me if I've overlooked something here. I've created a database using Visual Studio (add new item service-based database) called LoadForecast.mdf. I then created a table called ForecastsDB and added some fields. My main question is this: I've created a console application with the intention of writing some data to the newly created database. I've added LoadForecast.mdf as a data source for my program, but is there anything else I should do? I saw an example where the next step was adding a "data diagram", but this was for a visual application, not a console application. Do I still need to diagram the database for my console app? I just want to be able to write new records out to my database table and wasn't sure if there were any other things I needed to do for the VS environment to be "aware" of my database. Thanks for any advise!

• function taking in an input image and different kernel size

  - by drifterOcean19

  I have this filtering function that takes an input image, performs convolution using a given kernel, and returns the resulting image. However, I can't seem to work it out how to make it takes different kernel sizes.For example instead of pre-defined 3x3 kernel as below in the code, it could instead take 5x5 or 7x7. and then the user could input the type of kernel/filter they want(Depending on the intended effect). I can't seem to put my head around it. i'm quite new to matlab. function [newImg] = kernelFunc(imgB) img=imread(imgB); figure,imshow(img); img2=zeros(size(img)+2); newImg=zeros(size(img)); for rgb=1:3 for x=1:size(img,1) for y=1:size(img,2) img2(x+1,y+1,rgb)=img(x,y,rgb); end end end for rgb=1:3 for i= 1:size(img2,1)-2 for j=1:size(img2,2)-2 window=zeros(9,1); inc=1; for x=1:3 for y=1:3 window(inc)=img2(i+x-1,j+y-1,rgb); inc=inc+1; end end kernel=[1;2;1;2;4;2;1;2;1]/16; med=window.*kernel; disp(med); med=sum(med); med=floor(med); newImg(i,j,rgb)=med; end end end newImg=uint8(newImg); figure,imshow(newImg); end

  How can I play Blu-Ray movies via Windows Media Centre on Windows 8? If I choose the "play dvd" option, I get an error: Cannot Play Disc To play this DVD, you must first install a playback application that supports Blu-ray Disc.

• How can I display a dialog box for making a choice before a CALL is processed in android?

  - by jsight

  I would like to intercept outgoing calls and pass them to a VOIP application. I see that the Google Voice application has a feature for displaying a question before each call is actually initiated. It provides the user with the choice: Initiate call via Google Voice Initiate call via standard call I would like a way to do something similar with my application (so that not all calls have to be routed through it). At the moment, I can intercept CALL events via a BroadcastReceiver, however, these are not allowed to open dialogs (thus making it possible to display the choice). What is the best way of achieving this goal?

• Moving from WCF RIA RC to Release: best practices?

  - by Duncan Bayne

  I have an existing WCF RIA project built on the Release Candidate; I'm now moving to the Release version & have discovered many changes. David Scruggs made the following comment on his (MSDN) blog: "If you’ve written anything in SIlverlight 4 RIA Services, you’ll need to rewrite it. There has been a lot of refactoring and namespace moves." Having made a brief attempt to compile the old solution with the new RIA framework I'm inclined to agree. My current plan is to: remove the Silverlight Business Application projects from the Solution rebuild the EF4 items from the database create a new Silverlight Business Application project re-add the files (XAML, CS) from the old Silverlight Business Application project Does this sound like a reasonable approach? I think it's cleaner than trying to manually alter the existing project.

• How to enter text into the "Write something..." box on Facebook and click Submit

  - by Peter Payne

  Hello, I am trying to manipulate Facebook pages in various ways, using Javascript browser elements. I'd need to be able to insert some text into the top "Type something..." box that shows on my site's fan page (or alternately, "click into" the field and I can type the text using GUI scripting), then click the "submit" button as if i'd done it by hand. It's tricky since the page is very Ajax heavy and I can't find the names of the elements I need to manipulate, let alone how to manipulate them as they're not using traditional form fields I'm used to. Can anyone help me figure out how to do this with javascript commands, which I'd be calling from Applescript on the Mac? Many thanks in advance. UPDATE Thanks for the comments below. Believe me, I am not trying to do anything spammy or douchy, mainly posting links to products that have gone live on page facebook page, but do it during the business day when people are on rather than at strange hours of the day. I am located in Japan so my sleep period is right when people are using FB. The solution I came up with for clicking the button was got using UI Browser, an outstanding tool if you're trying to script on the Mac. The script that clicked the button for me was: tell application "Safari" activate set thename to name of (get current tab of window 1) delay 3 tell application "System Events" tell process "Safari" try click button "Share" of group 1 of group 2 of list 3 of group 9 of UI element 1 of scroll area 1 of group 3 of window thename -- this one works on the mini? on error click button "Share" of group 1 of group 2 of list 3 of group 9 of UI element 1 of scroll area 1 of group 2 of window thename -- did not work end try end tell end tell end tell Hope this is useful to anyone.
