Classic ASP to WCF using the Service Moniker

- by Jab

I am trying to consume a WCF logging service from classic ASP without deploy a Com wrapper. I found a method of doing so here. Here is the vb script, simplified. Dim addr addr = "service:mexAddress=""net.pipe://localhost/Services/Logging/LoggingManager/Mex""," _ & "address=""net.pipe://localhost/Services/Logging/LoggingManager/classic/""," _ & "contract=""ILoggingManagerClassic"", contractNamespace=""http://Services.Logging.Classic/""," _ & "binding=""NetNamedPipeBinding_ILoggingManagerClassic"", bindingNamespace=""http://Services.Logging.Classic/""" set objErrorLogger = GetObject(addr) Dim strError : strError = objErrorLogger.LogError("blahblah") This works on Server 2008, but fails with this error on Server 2003. Failed to do mex retrieval:Metadata contains a reference that cannot be resolved: net.pipe://localhost/Services/Logging/LoggingManager/Mex.. Only when running through ASP does it fail, a sample VBS file on the same machine using the same code works fine. I think it may be permission related, but don't know where to begin. Anyone have any ideas? EDIT - let me clarify that the WCF host is a windows service running as NETWORK SERVICE. If this belongs on server fault, a moderator can move it. I have an account there as well.

Building simple Reddit scraper

- by Bazant Fundator

Let's say that I would like to make a collection of images from reddit for my own amusement. I have ran the code on my development env and It haven't gone past the first page of posts (anything beyond requries the after string from the JSON. Additionally, When I turn on the validation, the whole loop breaks if the item doesn't pass it, not just the current iteration. I would be glad If you helped me understand mistakes I made. class Link include Mongoid::Document include Mongoid::Timestamps field :author, type: String field :url, type: String validates_uniqueness_of :url, # no duplicates validates :url, uniqueness :true end def fetch (count, after) count_s = count.to_s # convert count to string link = "http://reddit.com/r/aww/.json?count="+count_s+"&after="+after #so it can be used there res = HTTParty.get(link) # GET req. to the reddit server json = JSON.parse(res.body) # Parse the response if json['kind'] == "Listing" then # check if the retrieved item is a Listing for i in 1...(count) do # for each list item datum = json['data']['children'][i]['data'] #i-th element properties if datum['domain'].in?(["imgur.com", "i.imgur.com"]) then # fetch only imgur links Link.create!(author: datum['author'], url: datum['url']) # save to db end end count += 25 fetch(count, json['data']['after']) # if it retrieved the right kind of object, move on to the next page end end fetch(25," ") # run it

TDD vs. Unit testing

- by Walter

My company is fairly new to unit testing our code. I've been reading about TDD and unit testing for some time and am convinced of their value. I've attempted to convince our team that TDD is worth the effort of learning and changing our mindsets on how we program but it is a struggle. Which brings me to my question(s). There are many in the TDD community who are very religious about writing the test and then the code (and I'm with them), but for a team that is struggling with TDD does a compromise still bring added benefits? I can probably succeed in getting the team to write unit tests once the code is written (perhaps as a requirement for checking in code) and my assumption is that there is still value in writing those unit tests. What's the best way to bring a struggling team into TDD? And failing that is it still worth writing unit tests even if it is after the code is written? EDIT What I've taken away from this is that it is important for us to start unit testing, somewhere in the coding process. For those in the team who pickup the concept, start to move more towards TDD and testing first. Thanks for everyone's input. FOLLOW UP We recently started a new small project and a small portion of the team used TDD, the rest wrote unit tests after the code. After we wrapped up the coding portion of the project, those writing unit tests after the code were surprised to see the TDD coders already done and with more solid code. It was a good way to win over the skeptics. We still have a lot of growing pains ahead, but the battle of wills appears to be over. Thanks for everyone who offered advice!

Strange C++ performance difference?

- by STingRaySC

I just stumbled upon a change that seems to have counterintuitive performance ramifications. Can anyone provide a possible explanation for this behavior? Original code: for (int i = 0; i < ct; ++i) { // do some stuff... int iFreq = getFreq(i); double dFreq = iFreq; if (iFreq != 0) { // do some stuff with iFreq... // do some calculations with dFreq... } } While cleaning up this code during a "performance pass," I decided to move the definition of dFreq inside the if block, as it was only used inside the if. There are several calculations involving dFreq so I didn't eliminate it entirely as it does save the cost of multiple run-time conversions from int to double. I expected no performance difference, or if any at all, a negligible improvement. However, the perfomance decreased by nearly 10%. I have measured this many times, and this is indeed the only change I've made. The code snippet shown above executes inside a couple other loops. I get very consistent timings across runs and can definitely confirm that the change I'm describing decreases performance by ~10%. I would expect performance to increase because the int to double conversion would only occur when iFreq != 0. Chnaged code: for (int i = 0; i < ct; ++i) { // do some stuff... int iFreq = getFreq(i); if (iFreq != 0) { // do some stuff with iFreq... double dFreq = iFreq; // do some stuff with dFreq... } } Can anyone explain this? I am using VC++ 9.0 with /O2. I just want to understand what I'm not accounting for here.

"Work stealing" vs. "Work shrugging (tm)"?

- by John

Why is it that I can find lots of information on "work stealing" and nothing on a "work shrugging(tm)" as a load-balancing strategy? I am surprised because work-stealing seems to me to have an inherent weakness when implementating efficient fine-grained load-balancing. Vis:- Relying on consumer processors to implement distribution (by actively stealing) begs the question of what these processors do when they find no work? None of the work-stealing references and implementations I have come across so far address this issue satisfactorarily for me. They either:- 1) Manage not to disclose what they do with idle processors! [Cilk] (?anyone know?) 2) Have all idle processors sleep and wake periodically and scatter messages to the four winds to see if any work has arrived [e.g. JAWS] (= way too latent & inefficient for me). 3) Assume that it is acceptable to have processors "spinning" looking for work ( = non-starter for me!) Unless anyone thinks there is a solution for this I will move on to consider a "Work Shrugging(tm)" strategy. Having the task-producing processor distribute excess load seems to me inherently capable of a much more efficient implementation. However a quick google didn't show up anything under the heading of "Work Shrugging" so any pointers to prior-art would be welcome. tx Tags I would have added if I was allowed to [work-stealing]

Subversion versus Vault

- by WebDude

I'm currently reviewing the benefits of moving from SVN to a SourceGear Vault. Has anyone got advice or a link to a detailed comparison between the two? Bear in mind I would have to move my current Source Control system across which works strongly in SVN's favor Here is some info I have found out thus far from my own investigations. I have been taking some time tests between the two and vault seems to perform most operations much faster. Time tests used the same server as the repository, the same workstation client, and the same project. Time Comparisons SVN Add/Commit 12:30 Get Latest Revision 5:35 Tagging/Labelling 0:01 Branching N/A - I don't think true branching exists in SVN Vault Add/Commit 4:45 Get Latest Revision 0:51 Tagging/Labelling 0:30 Branching 3:23 (can't get this to format correctly) I also found an online source comparing some other points. This is the kind of information i'm looking for. Usage Comparisons Subversion is edit/merge/commit only. Vault allows you to do either edit/merge/commit or checkout/edit/checkin. Vault looks and acts just like VSS, which makes the learning curve effectively zero for VSS users. Vault has a VS plugin, but it only works if you're going to run in checkout-mode. Subversion has clients for pretty much every OS you can imagine; Vault has a GUI client for Windows and a command line client for Mono. Both will support remote work, since both use HTTP as their transport (Subversion uses extended DAV, Vault uses SOAP). Subversion installation, especially w/ Apache, is more complex. Subversion has a lot of third party support. Vault has just a few things. My question Has anyone got advice or a link to a detailed comparison between the two?

what's the correct way to release a new website?

- by kk

so i've been working on a website on and off for about a year now, and i'm finally at a point where it's functional enough to test out in a sort of private beta (not ready for live release). but i never thought about the correct process for doing this and what things i need to take care of. i've never released a public website before. some of the questions/concerns i have in mind: 1) is it against my MSDN license agreement to release a website using the software? 2) how do i protect my "idea"? is it a bad idea to find random people you don't know to test out your site? can you make them digitally sign some sort of NDA? 3) i'm using some open source code - any proper way to release open source code to live production? 4) how much traffic can a place like discountasp.net handle anyway? can hosting sites generally handle large volume of traffic? any comments/suggestions regarding the proper/safe way to release a public website would be appreciated. i've been working on this for a while and never actually sat down to think about the right way to move from a personal side project to a live production website.

Modified jQuery innerfade sluggish

- by Jay Hankins

HI. I am using the jQuery innerfade plugin to scroll through some images on my site. Innerfade is sluggish to move on Firefox 3.6.3, and IE 8. IE 8 is much worse than Firefox, and Chrome runs smoothly. Can you analyze my code to see what the problem is? I've used the modified innerfade from here: http://www.stylephp.com/2009/01/17/customizing-jquery-innerfade-plug-in-adding-controls-navigation-and-caption/ My sites are here: Without bg image: http://dl.dropbox.com/u/145908/doozie2/index.html With bg image: http://dl.dropbox.com/u/145908/doozie2/index2.html Removing my background image fixes the situation; it's not that big of a file. I don't understand why that is an issue. I am using a technique to resize the image to fit the browser window, as you can see in the CSS. Thanks so much. P.S. Sorry, I'm a new user so I can't post more than one link. Please copy and paste the address between <.

Right to Left UI in iPhone (Hebrew)

- by Reflog

Hello, I'm struggling in creating a RTL UI in iPhone application. The framework doesn't seem to have any support for RTL languages. The only thing is the alignment inside labels, which is nice, but it conflicts with other controls behaviour. The question is: Is there a working code for a RTL TableView? Something that would handle the disclosure buttons to be on the left, section titles to be right aligned, index view to be left aligned? As far as I understand I cannot move the index view of the tableview, i have to overlay some custom control... Any suggestions/pointers/examples? p.s. this is not a duplication of this question: http://stackoverflow.com/questions/1677988/right-to-left-alignment-for-uitableview since what I am looking for is a deeper customization, not just a new type of CellView. (Update: Mar 10) For now - I've removed support for indexView from the tableView at all, implemented the cells as custom views by myself (with disclosure buttons on the left), and customized the header/footer of the table as well. the only thing that is left is the Index View. Thanks in advance!

How to continuously scroll content within a DIV using jQuery?

- by Camsoft

Aim The aim is to a have a container DIV with a fixed height and width and have the HTML content within that DIV automatically scroll vertically continuously. Question Basically I've created the code below using jQuery to scroll (move) the child DIV vertically upwards until its outside the bounding parent box where the animation then completes which triggers an event handler which resets the position of the child DIV and starts the process again. This works fine, so the content scrolls up leaving a blank space and then starts from the bottom again and scrolls up. The problem I have is that the requirements for this is for the content to appear as if it was continuously repeating, see below diagram to better explain this, is there a way to do this? (I don't want to use 3rd party plug ins or libraries other than jQuery): What I have so far The HTML: <div id="scrollingContainer"> <div class="scroller"> <h1>This is a title</h1> <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Suspendisse at orci mi, id gravida tellus. Integer malesuada ante sit amet enim pulvinar congue. Donec pulvinar dolor et arcu posuere feugiat id et felis.</p> <p>More content....</p> </div> </div> The CSS: #scrollingContainer{ height: 300px; width: 300px; overflow: hidden; } #scrollingContainer DIV.scroller{ position: relative; } The JavaScript: /** * Scrolls the content DIV */ function scroll() { if($('DIV.scroller').height() > $('#scrollingContainer').height()) { var t = $('DIV.scroller').position().top + $('DIV.scroller').height(); /* Animate */ $('DIV.scroller').animate( { top: '-=' + t + 'px' } , 4000, 'linear', animationComplete); } } function animationComplete() { $(this).css('top', $('#scrollingContainer').height()); scroll(); }

Changing a sprites bitmap

- by numerical25

As of right now, I am trying to create a tiling effect for a game I am creating. I am using a tilesheet and I am loading the tiles to the sprite like so... this.graphics.beginBitmapFill(tileImage); this.graphics.drawRect(30, 0,tWidth ,tHeight ); var tileImage is the bitMapData. 30 is the Number of pixels to move retangle. then tWidth and tHeight is how big the rectangle is. which is 30x30 This is what I do to change the bitmap when I role over the tile this.graphics.clear(); this.graphics.beginBitmapFill(tileImage); this.graphics.drawRect(60, 0,tWidth ,tHeight ); I clear the sprite canvas. I then rewrite to another position on tileImage. My problem is.... It removes the old tile completely but the new tile positions farther to the right then where the old bitmap appeared. My tile sheet is only 90px wide by 30px height. On top of that, it appears my new tile is drawn behind the old tile. Is there any better way to perfect this. again, all i want is for the bitmap to change colors

Silverlight 4 race condition with DataGrid master details control

- by Simon_Weaver

Basically I want a DataGrid (master) and details (textbox), where DataGrid is disabled during edit of details (forcing people to save/cancel)... Here's what I have... I have a DataGrid which serves as my master data. <data:DataGrid IsEnabled="{Binding CanLoad,ElementName=dsReminders}" ItemsSource="{Binding Data, ElementName=dsReminders}" > Its data comes from a DomainDataSource: <riaControls:DomainDataSource Name="dsReminders" AutoLoad="True" ... I have a bound Textbox which is the 'details' (very simple right now). There are buttons (Save/Cancel) which should be enabled when user tries to edit the text. Unfortunately Silverlight doesn't support UpdateSourceTrigger=PropertyChanged so I have to raise an event: <TextBox Text="{Binding SelectedItem.AcknowledgedNote, Mode=TwoWay, UpdateSourceTrigger=Explicit, ElementName=gridReminders}" TextChanged="txtAcknowledgedNote_TextChanged"/> The event to handle this calls BindingExpression.UpdateSource to update the source immediately: private void txtAcknowledgedNote_TextChanged(object sender, TextChangedEventArgs e) { BindingExpression be = txtAcknowledgedNote.GetBindingExpression(TextBox.TextProperty); be.UpdateSource(); } IN other words - typing in the textbox causes CanLoad of the DomainDataSource to become False (because we're editing). This in turn disables the DataGrid (IsEnabled is bound to it) and enables 'Cancel' and 'Save' buttons. However I'm running up against a race condition if I move quickly through rows in the DataGrid (just clicking random rows). The TextChanged presumably is being called on the textbox and confusing the DomainDataSource which then thinks there's been a change. So how should I disable the DataGrid while editing without having the race condition? One obvious solution would be to use KeyDown events to trigger the call to UpdateSource but I always hate having to do that.

NAnt not running NUnit tests

- by ctford

I'm using NUnit 2.5 and NAnt 0.85 to compile a .NET 3.5 library. Because NAnt 0.85 doesn't support .NET 3.5 out of the box, I've added an entry for the 3.5 framework to NAnt.exe.config. 'MyLibrary' builds, but when I hit the "test" target to execute the NUnit tests, none of them seem to run. [nunit2] Tests run: 0, Failures: 0, Not run: 0, Time: 0.012 seconds Here are the entries in my NAnt.build file for the building and running the tests: <target name="build_tests" depends="build_core"> <mkdir dir="Target" /> <csc target="library" output="Target\Test.dll" debug="true"> <references> <include name="Target\MyLibrary.dll"/> <include name="Libraries\nunit.framework.dll"/> </references> <sources> <include name="Test\**\*.cs" /> </sources> </csc> </target> <target name="test" depends="build_tests"> <nunit2> <formatter type="Plain" /> <test assemblyname="Target\Test.dll" /> </nunit2> </target> Is there some versioning issue I need to be aware of? Test.dll runs fine in the NUnit GUI. The testing dll is definitely being found, because if I move it I get the following error: Failure executing test(s). If you assembly is not build using NUnit 2.2.8.0... Could not load file or assembly 'Test' or one of its dependencies... I would be grateful if anyone could point me in the right direction or describe a similary situation they have encountered. Edit I have since tried it with NAnt 0.86 beta 1, and the same problem occurs.

Heroku taps push weirdness...

- by holden

I have the strangest experience using taps to move data between my machine and heroku. It works fine except that it seems to loose 0s directly behind the decimal place for my geo coordinates. Ie 50.0519322 for some reason gets set to 50.519322... no idea why. When I pull the data from the remote location ie. heroku db:pull... it works fine, all decimal places intact on my machine, however, when i push it back to the remote server it loses these zeros. Especially directly behind the decimal place, though I haven't noticed it elsewhere yet. At first I was storing the lat and lng as simply numeric but refined it to: change_column :places, :lat, :numeric, :precision => 15, :scale => 10 change_column :places, :lng, :numeric, :precision => 15, :scale => 10 With no result, any ideas what's going on? From the console on the remote server i get the lat as being: #<BigDecimal:2aebcc5967c0,'0.50519322E2',18(18)> and my machine as: #<BigDecimal:10232f7c8,'0.50519322E2',12(16)> which is also odd, the second one because it shows up as 50.0519322 when i edit it thru my view but when i do to_f via console it gives me 50.519322

DWM and painting unresponsive apps

- by Doug Kavendek

In Vista and later, if an app becomes unresponsive, the Desktop Window Manager is able to handle redrawing it when necessary (move a window over it, drag it around, etc.) because it has kept a pixel buffer for it. Windows also tries to detect when an app has become unresponsive after some timeout, and tries to make the best of the situation -- I believe it dims out the window, adds "Not Responding" to its title bar, and perhaps some other effects. Now, we have a skinned app that uses window regions and layered windows, and it doesn't play well with these effects. We've been developing on XP, but have noticed a strange effect when testing on Vista. At some points the app may spend a few moments on some calculation or callback, and if it passes the unresponsive threshold (I've read that it's a five second timeout, but I cannot find a link), a strange graphical problem occurs: any pixels that would be 100% transparent due to the window regions turn black, which effectively makes the window rectangular again, with a black background. There seem to be other anomalies, with the original window's pixels being shifted a bit in some child dialogs. I am working on reducing such delays (ideally Windows will never need to step in like this), and trying to maintain responsiveness while it's busy, but I'd still like to figure out what is causing it to render like that, as I can't guarantee I can eliminate all delays. Basically, I just would like to know what Windows is doing when this happens, and how I can make my app behave properly with it. Skinned apps have to still work on Vista and later, so I need to figure out what I'm doing that's non-standard. I don't even know exactly how to look for information into how Windows now handles unresponsive apps, as my searches only return people having issues with apps that are unresponsive, or very rudimentary explanations of what the DWM does with such apps. Heck I'm not even 100% sure it's the DWM responsible, but it seems likely. Any potential leads? Photo of problem; screen shots won't capture the effect (note that the white dialog's buffer is shifted -- it is shifted exactly by the distance it has been offset from the main (blue) window):

uitableview reloadData issue

- by CocoaNewBee

I've been debugging my iphone app and found something interesting. I have a UIViewControllers with TabBarcontroller( 6 tabs). each tab is a UIViewController and it has a UITtableview. The viewDidLoad works and brings the initial data. On of the UITableView has a search bar. After the user touchs presses search some magic happens and I get an array with data. I cant see the new data in the tableview and the [tableView reloadData] has no effect outside viewDidLoad (first time). I can see the array holding the data and the dataSource is set to self. Yet, no displaying of data! so I 've tried [self.tableView reloadData] & [self.tableView setNeedsDisplay] Funny enough, the new data is not being displayed. However if I move the table up or down the cellForRowAtIndexPath is being fired and the first row shows data. can anyone shed some light on this mystery??? if there a [self.view refreshscreen] ??

Problem with UIScrollView

- by leon

Hi, Sorry for long winded post. I am trying to understand UIScrollView and running into very simple problem. I am creating a scroll view I am making this view 1.5 size larger then normal size Using UIScrollView I expect to see some edge elements of view out of bounds, but should be able to pan the view therefore bringing missing elements back to the visible area. However I am seeing that I can't just pan/scroll view anyway I want, instead view always wants to scroll up, as soon as move away my finger from the screen (touch end event). I am not handling any touches, etc - I just want to understand why does not scaled view stay put where I scroll it? CGRect viewFrame = self.view.frame ; viewFrame.size.width *= 1.5; viewFrame.size.height *= 1.5; CGSize mySize = viewFrame.size; [ ((UIScrollView *) self.view) setContentSize: mySize]; self.view.transform = CGAffineTransformMakeScale(1.5, 1.5); What I really trying to accomplish is something similar to Number on iPad (the same code will work on iPhone): There is a view with lots of controls on it (order entry form) User can zoom into the entire form so all elements look bigger user can pan the form therefore bringing various elements into the visible area of the screen. It seems that UIScrollView can should be able to handle zoom and pan actions (for now I am using Affine Transform to zoom in to the order entry form and iPad) Thanks

Not all TFS Build type files are getting copied

- by k4k4sh1

Because I have several builds sharing some assemblies containing common build tasks, I have one TFSBuild.proj for all builds and import different targets depending on the build, like the following: <Project DefaultTargets="DesktopBuild" xmlns="http://schemas.microsoft.com/developer/msbuild/2003" ToolsVersion="3.5"> <Import Project="Build_1.targets" Condition="'$(BuildDefinition)'=='Build_1'" /> <Import Project="Build_2.targets" Condition="'$(BuildDefinition)'=='Build_2'" /> <Import Project="Build_3.targets" Condition="'$(BuildDefinition)'=='Build_3'" /> </Project> Each target for a particular build has your usual content for a build type file, but in my case, I also reference some tasks inside assemblies checked into the same folder as TFSBuild.proj in source control. I wanted to add folders to contain some test build targets, since my folder was getting a bit full and cluttered. The following illustrates what I mean. $(TFS project)\build\ TFSBuild.proj Build_1.targets ... Assembly1.dll Assembly2.dll ... Folder\ Test_target_1.targets .... When I stated my build, however, I found that Test_target_1.targets and other files in Folder were not being copied to the build directory, while TFSBuild.proj and other files in the root level, as it were, of the build type folder were being copied. This caused my test build to not be able to reference files inside Folder, causing my build to immediately fail. I realize the simplest work-around would be to get rid of Folder and move all of its contents up to the build folder, but I would really like to have Folder if at all possible. Thanks for your help in advance.

Dynamically manipulate php cookies with javascript/jquery

Hi guys, I'm currently building a dynamic menu bar(vertical and horizontal). in the default position its vertical. the user have the option to show the horizontal position and hide and vertical. I am currently doing that with javascript/ jquery. in order to keep the menu bar in the horizontal position i am keeping a count with a cookie. the problem is that when i use the click function in javascript i want to change the value of the cookie. i have no knowledge of how to do this. Can anyone assist me with this. all help would be appreciated. <?php setcookie('menu', 1, time()+(86400)); ?> $(document).ready(function() { $('#temp').hide(); if(<?php echo $_COOKIE['menu'];?> == 1){ $('#topmenu').hide(); $('#sidemenu').floating().dropShadow().floating(); $('#sidemenu_bottom').hide(); }else{ $('#topmenu').show(); $('#topmenu').dropShadow(); $('#sidemenu').hide(); $('#sidemenu').removeShadow(); } $('#move').click(function(){ $('#sidemenu').hide("drop",{},2000); $('#sidemenu').removeShadow(); $('#topmenu').show(); $('#topmenu').dropShadow(); $('#sidemenu_bottom').show(); $('#sidemenu_bottom').floating().dropShadow().floating(); }); }); This is what i have so far and the default cookie is working as well as the javascript. its just to change the cookie value now. thanks.

Apache Tomcat under Windows: Changing webapps default directory

- by Maerch

I am deploying my Java application with Ant. Unfortunately my test deployment on the local machine doesn't work because of Vista. The Program Files directionaries are protected and i don't want to start Ant or Eclipse as an Admin. So i had the idea to move my webapps folder to a workspace subfolder, so i can use relative paths in Ant as well. The solutions seems to be to modify the Host element in the server.xml. With Linux it isn't such a deal: <Host name="localhost" appBase="/path/to/webapps" unpackWARs="true" autoDeploy="true" xmlValidation="false" xmlNamespaceAware="false"> But with Windows i don't get it right. I tried every possible combinations i could imagine, like: C://Users//maerch//Workspaces//Tomcat6.0_webapps C:/Users/maerch/Workspaces/Tomcat6.0_webapps C:\Users\maerch\Workspaces\Tomcat6.0_webapps C:\\Users\\maerch\\Workspaces\\Tomcat6.0_webapps C://Users//maerch//Workspaces//Tomcat6.0_webapps\\ C:/Users/maerch/Workspaces/Tomcat6.0_webapps/ C:\Users\maerch\Workspaces\Tomcat6.0_webapps\ C:\\Users\\maerch\\Workspaces\\Tomcat6.0_webapps\\ The path is also correct, but it doesn't work. There are also no error messages in the log files neither the browser shows a 404 message or anything else. Just a white page without title and so on. Can anyone help?

Fixed mouse pointer with jQuery draggable

- by MikeWyatt

I'm building a little game in HTML5. The canvas element is a viewport into the game world. The user can move the viewport's position in the world by clicking and dragging with the mouse on a small icon. The problem is that the scrolling stops when the mouse pointer hits the edge of the screen. In all likelihood, that will limit scrolling in one of the directions severely, since the icon will be in one of the corners of the page. The only technical solution I can think of would be to somehow fix the mouse pointer's position on the icon and detect the relative movement each frame. Basically I would just reset the pointer position back to the center of the icon after each drag event. Unfortunately, I'm fairly positive that this is not possible. Playing with the user's pointer is a big no-no from a usability and security standpoint. So, is there any other way to do what I want? I'm primarily looking for technical ideas here, but suggestions for a more appropriate interface would also be welcome.

"</a> </li>"; } echo ''; Current Output: School A School A School B School B School B School C School C Expected Output: School name displayed only once (distinct won't work because each school name has 2-3 product credentials School A School B School C Ability for User to click on a school. then the school names underneath will move down (toggle effect) and user can see product, username and password displayed for the school clicked (for example: user clicked on School A) School A productname1, username, password productname2, username, password School B School C

Flush separate Castle ActiveRecord Transaction, and refresh object in another Transaction

- by eanticev

I've got all of my ASP.NET requests wrapped in a Session and a Transaction that gets commited only at the very end of the request. At some point during execution of the request, I would like to insert an object and make it visible to other potential threads - i.e. split the insertion into a new transaction, commit that transaction, and move on. The reason is that the request in question hits an API that then chain hits another one of my pages (near-synchronously) to let me know that it processed, and thus double submits a transaction record, because the original request had not yet finished, and thus not committed the transaction record. So I've tried wrapping the insertion code with a new SessionScope, TransactionScope(TransactionMode.New), combination of both, flushing everything manually, etc. However, when I call Refresh on the object I'm still getting the old object state. Here's some code sample for what I'm seeing: Post outsidePost = Post.Find(id); // status of this post is Status.Old using (TransactionScope transaction = new TransactionScope(TransactionMode.New)) { Post p = Post.Find(id); p.Status = Status.New; // new status set here p.Update(); SessionScope.Current.Flush(); transaction.Flush(); transaction.VoteCommit(); } outsidePost.Refresh(); // refresh doesn't get the new status, status is still Status.Old Any suggestions, ideas, and comments are appreciated!
