• MembershipProvider, IPrincipal, IIdentity?

  - by MRFerocius

  Hello guys; I have a conceptual question... I am making an Intranet application (Web platform) for a company. I have a SQL Server DB with these tables: Users (userID, userName, userPass, roleID) Roles (roleID, roleName) Pages (pageID, pageURL) RolesXPages(pageID, roleID) How is the best way to create a structure to store all this information while the user navigates the site, I mean, on the thread I should be able to check his role, his pages (the ones he can access) I have been reading and there is a lot of stuff there where Im confused, I saw the MembershipProvider, IPrincipal, IIdentity, etc classes but Im not sure what should be the best one for me. Any thoughts... Thanks in advance! Edit: Everytime gets more confusing... I just want to handle those structures at runtime and be able to mantain state during page callbacks or changing pages...

• WebTest Visual Studio Test problems with amf call

  - by Lieven Cardoen

  If I browse to a flex application when recording with VS Test, I can see the calls to WebORB (amf calls). However, when stopping the recording this is what happens: First, Visual Studio detects dynamic parameters, but stays around 20%, and never gets through it. Second, if I cancel the detecting dynamic parameters, and run the web test, the calls to WebORB (amf calls) do not work. In fact, in VS2010, the call to WebORB stays on Submitting... Now, this web test, does it only record url's and query string variables, or does it record the whole request? If it records the whole request, the call to WebORB should work, but it doesn't.

• List of objects to JSON to Html Table?

  - by DaveDev

  If I have a list of objects IEnumerable<MyType> myTypes; Is it possible for me to return this to the client as JSON return Json(myTypes); and if so, is it possible for me to convert this (now JSON format) list to a when it gets to the client? Is there any jQuery plugin to do this? The thing is, there's loads of other stuff I need to send as JSON also, so generating a table with a PartialView and embedding that into the JSON is a extra complexity that I'd like to avoid. Thanks.

• calling wcf from asp.net mvc - authorization error

  - by niao

  Greetings, My asp.net mvc application calls WCF service. Everything is ok on my localhost (WinXP, IIS6). When I moved on production server where Win2008 Server and IIS7 are used my application gets authorization error while connecting to WCF service. ASP.NET MVC works ok but when it calls some methods on my WCF Service an error is thrown. The funny thing is that when I calls the same WCF Production service from the same ASP.NET MVC application hosted on my localhost it works ok. Can someone please help me with this. I think it's authorization problem which can be fixed on IIS7. Am I right?

• A very weired problem with texbox control in C# .net

  - by Kazoom

  Well i know textbox is a very simple user control, perhaps the first input control ever made. I have been facing a very frustrating problem with this simple control. I programatically add a textbox in my user control. From ui i am able to edit it like a normal textbox. however, i am not able to read the user inputed value in the program. my program all the time sees the old value with which my text box was initialized. i textchange event getting triggered but the value never gets updated. This seemingly looks to be some innocuous bug in the code, but the program is very simple and it does not seem to be having any bug. Any guidelines on this issue?

• Indy FTP, large files and NAT routers

  - by Lobuno

  Hello! I have been using Indy to transfers files via FTP for years now but have not been able to find a satisfactory solution for the following problem. When a user is uploading a large file, behind a router, sometimes the following happens: the file is uploaded OK, but under the mean time the command channel gets disconnected because of a timeout. Normally this doesn't happens with a direct connection to the server, because the server "knows" that a transfer is being taking place on the data channel. Some routers are not aware of this, though and the command channel is closed. Many programs send a NOOP command periodically to keep the command channel alive even if this is not part of the standard FTP specification. My question: how do I do that? Do I send the NOOP command in the OnWork event? Does this cause any collateral damage in some way, like, do I need to process some response? How do I best solve this problem?

• Flex 4 Spark VideoDisplay in Popup causes memory leak

  - by Ben

  Hi, I'm currently building an air app with FB 4. I have a custom control that contains a VideoDisplay control, and which loaded using the PopupManager. Using the profiler, i've noticed that every time the my popup is loaded the memory for it gets allocated, but when it's closed the memory is never recovered. There's nothing else holding a reference to the popup. And if I don't set the source of the VideoDisplay object, then there is no leak - but as soon as the source is set I get a leak. I can't see any method to force close the stream or anything on the spark VideoDisplay control. Any idea or suggestions? EDIT: I have tried setting the source to null before closing the popup but that doesn't change anything. Also, I'm not holding any event listener to the video

• PHP Curl's Proxy feature causes no information to be returned

  - by Grant David Bachman

  I'm working on a PHP script right now which sends requests to our school's servers to get real-time information about class sizes for different courses. The script runs perfectly fine when I don't use a proxy, returning a string full of course numbers and available seats. However, I want to make this a service for the students, and I'm afraid that if I make too many requests my ip will get blocked. So I'm attempting to do this through a proxy, with no success. As soon as I add the CURLOPT_HTTPPROXYTUNNEL and CURLOPT_PROXY fields to my requests nothing gets returned. I'm not even sure how to troubleshoot it at this point since I'm not getting an error message of any kind. Does anyone know what's going on or how to at least troubleshoot it?

• From iPhone OS to cocoa on OSX...

  - by David

  Hi - this is quite a basic OSX/cocoa question. I come from an iPhone OS development background. I'm now trying to write apps for OSX, but I don't understand where cocoa on OSX decides where the program gets control. I can see the main function, but where does program control go from there? Say for example I want to programatically create a window with an NSView in it once the app has finished launching - how would I do that? There is no app delegate created that I can see, in iPhone OS I would wait for the - (void) applicationDidFinishLaunching:(UIApplication *)application method to be called. I really don't want to use the Interface Builder or NIB files to setup my window/view. How would I go about this? Any help would be much appreciated - Cheers, David

• How can I stop Silverlight DataForm immediately saving changes back to underlying object?

  - by Simon_Weaver

  I have a Silverlight master-details DataForm where the DataForm represents a street address. When I edit the Address1 textbox, the value gets automatically committed to the bound Address object once focus leaves the textbox. If I hit the Cancel button, then any changes are undone because Address implements IEditableObject and saves its state. The problem is that since any change is immediately propagated to the underlying object it will be shown in the master grid before the user has actually hit Save. I also have other locations where this data is shown. This is not a very good user experience. I've tried OneWay binding but then I can't commit back without manually copying all the fields over. The only thing I can think of doing is to create a copy of the data first or using OneWay binding, but they both seem a little clumsy. Does DataForm support this way of working?

• What is the least intrusive way to display WPF tooltip on focus?

  - by Andrey Shchekin

  What is the minimum number of steps required to display a tooltip when the following control gets focus? <TextBox ToolTip="Hello there!" ... /> I tried the following in GotFocus private void ..._GotFocus(object sender, RoutedEventArgs e) { var element = (FrameworkElement)sender; var tooltip = element.ToolTip; if (!(tooltip is ToolTip)) { tooltip = new ToolTip { Content = tooltip }; element.ToolTip = tooltip; } ((ToolTip)tooltip).IsOpen = true; } However, it seems to ignore the ToolTipService.Placement for this control and SystemParameters.ToolTipPopupAnimationKey set up level higher. How can I make it work and honor all settings that generally work for tooltips (except the timing, obviously)?

• How to stop SWF inside of a jQuery UI tab from reloading

  - by Raul Agrait

  I have a SWF movie inside of a jQuery UI tab, and the problem I'm having is that the SWF gets reloaded everytime I click away from the tab, onto another tab, and then click back. I can inspect the DOM and see that the div containing the SWF is still in the DOM when I click away, so I don't know why this it seems to reload it when I click back to the tab. I added the following CSS rules to try to prevent the display being set to: none, but the Flash movie is still reloading: .ui-tabs .ui-tabs-hide { display: block !important; position: absolute; left: -10000px; }

• Jquery UI Slider focus issue

  - by Webbo

  I have a problem with the jQuery UI Slider. The issue also appears on the demo. It is more obvious in Chrome - if you go to http://jqueryui.com/demos/slider/#steps and slide the slider, you'll not see anything wrong. If you then click "New Window" or go to (http://jqueryui.com/demos/slider/steps.html) to view the demo in a new window and try sliding the slider, you'll see the handle of the slider gets a focus box around it during dragging. I am having this problem and I cannot seem to fix it. Can anyone point me in the right direction?

• VS2010 / Code Analysis: Turn off a rule for a project without custom ruleset....

  - by TomTom

  ...any change? The scenario is this: For our company we develop a standard how code should look. This will be the MS full rule set as it looks now. For some specific projects we may want to turn off specific rules. Simply because for a specific project this is a "known exception". Example? CA1026 - while perfectly ok in most cases, there are 1-2 specific libraries we dont want to change those. We also want to avoid having a custom rule set. OTOH putting in a suppress attribute on every occurance gets pretty convoluted pretty fast. Any way to turn off a code analysis warning for a complete assembly without a custom rule set? We rather have that in a specific file (GlobalSuppressions.cs) than in a rule set for maintenance reasons, and to be more explicit ;)

• Jabber integration into site and multiple domains

  - by Jamie

  Hi all, I'm creating a centralised web product, i.e. a customer gets assigned a personal domain, for example company1.example.com or company2.example.com and can then use our service. I'm planning to integrate a jabber service into the website. I have already found a decent jabber client library which I can use for the site. I know that jabberd2 uses mysql, which is perfect because I want to use the web interface to add users, delete users, view message logs etc. However, my problem is when I have two companies or more. I would like a jabber server which can host multiple domains, i.e. jabber.company1.example.com, jabber.company2.example.com Do you have any experience of this? And do you know of a good jabber server which will do this? Any help would be hugely appreciated!

• ASP.NET FormsAuthentication Cookie Problem

  - by Niels Bosma

  We use FormAuthentication to manage logins and I have a case where a customer complains where he can login from one computer but to from another. I can see in my logs that his authentican is successfull but he gets bumped back to the login page. I can reproduce the symptons by disabling cookies so I asked the customer to test if cookies are enabled on http://www.tempesttech.com/cookies/cookietest1.asp, but this came out positive. What have I missed? Is there any antivirus/security software that can mess up (ASP.NET) cookies? The user is using IE7 and claims to have F-secure installed.

• How to use RadSpell within a Telerik MVC Grid editor popup?

  - by Brian David Berman

  Is it possible to use RadSpell within a Telerik MVC Grid editor popup? I have followed some of the examples online to use RadSpell with ASP.NET MVC (http://www.telerik.com/help/aspnet-ajax/mvc-using-spellchecker.html and http://www.telerik.com/help/aspnet-ajax/spell-client-side-api.html) and I am able to attach multiple text controls to check but the display gets messed up when using Telerik MVC Grid editor popups since it's already in a modal. Sometimes it will randomly pick another div on the page and treats it like it's the main window (it will gray out just a portion of the page and I'll see the RadSpell popup peeking through but it's unusable). It seems like it chooses different places in the DOM to inject the iframe/radwindow for RadSpell as well. Any ideas? I didn't include any code because my implementation is a mess and I'd prefer to start with something simpler, from scratch.

• Alternative to Nested Loop For Comparison

  - by KGVT

  I'm currently writing a program that needs to compare each file in an ArrayList of variable size. Right now, the way I'm doing this is through a nested code loop: if(tempList.size()>1){ for(int i=0;i<=tempList.size()-1;i++) //Nested loops. I should feel dirty? for(int j=i+1;j<=tempList.size()-1;j++){ //*Gets sorted. System.out.println(checkBytes(tempList.get(i), tempList.get(j))); } } I've read a few differing opinions on the necessity of nested loops, and I was wondering if anyone had a more efficient alternative. At a glance, each comparison is going to need to be done, either way, so the performance should be fairly steady, but I'm moderately convinced there's a cleaner way to do this. Any pointers?

• Perl graph garbage collection usage

  - by Kevin

  Hi, I have built a tiny application in Perl that displays a graph over time. It graphs garbage collection usage over time. I use gnuplot to display the actual graph. This works fine if the time period is short, like a few hours. However, as the time increases (say a few days), the graph becomes difficult to read as the information gets crammed. Note that there is a tool called gcviewer which performs a similar function, it works by allowing you to choose the percentage of the graph. http://www.tagtraum.com/gcviewer.html Ideally I would like to take this further by adding the ability to "move" within the graph. I am not a developer but am good at scripting, so if there is some module in Perl which would provide this functionality it would be excellent! However, if it cannot be done in Perl, I am not averse to learning a new technology. Inputs are highly appreciated. Thanks!

• When creating a new IIS web site, how can I add it to an existing application pool?

  - by Ian Robinson

  I have successfully automated the process of creating a new IIS website, however the code I've written doesn't care about application pools, it just gets added to DefaultAppPool. However I'd like to add this newly created site to an existing application pool. Here is the code I'm using to create the new website. var w3Svc = new DirectoryEntry(string.Format("IIS://{0}/w3svc", webserver)); var newsite = new object[] { serverComment, new object[] { serverBindings }, homeDirectory }; var websiteId = w3Svc.Invoke("CreateNewSite", newsite); site.Invoke("Start", null); site.CommitChanges(); <update Although this is not directly related to the question, here are some sample values being used above. This might help someone understand exactly what the code above is doing more easily. webServer: "localhost" serverComment: "testing.dev" serverBindings: ":80:testing.dev" homeDirectory: "c:\inetpub\wwwroot\testing\" </update If I know the name of the application pool that I'd like this web site to be in, how can I find it and add this site to it?

• Question about XML deserialization in .net

  - by ryudice

  Hi, I'm trying to deserialize an XML that comes from a web service but I do not know how to tell the serializer how to handlke this piece of xml: <Movimientos> <Movimientos> <NOM_ASOC>pI22E7P30KWB9KeUnI+JlMRBr7biS0JOJKo1JLJCy2ucI7n3MTFWkY5DhHyoPrWs</NOM_ASOC> <FEC1>RZq60KwjWAYPG269X4r9lRZrjbQo8eRqIOmE8qa5p/0=</FEC1> <IDENT_CLIE>IYbofEiD+wOCJ+ujYTUxgsWJTnGfVU+jcQyhzgQralM=</IDENT_CLIE> </Movimientos> <Movimientos> As you can see, the child tag uses the same tag as its parent, I suppose this is wrong however the webservice is provided by an external company and that wont change it, is there any way or any library to tidy up XML or how can I use an attribute on my class so that the serializer gets it right? thanks for any help.

• Advice on HTTPS connections using Ruby on Rails

  - by user502052

  Since I am developing a "secure" OAuth protocol for my RoR3 apps, I need to send protected information over the internet, so I need to use HTTPS connections (SSL/TSL). I read How to Cure Net::HTTP’s Risky Default HTTPS Behavior aticle that mentions the 'always_verify_ssl_certificates' gem, but, since I want to be more "pure" (it means: I do not want to install other gems, but I try to do everything with Ruby on Rails) as possible, I want to do that work without installing new gems. I read about 'open_uri' (it is also mentioned in the linked article: "open_uri is a common exception - it gets things right!") that is from the Ruby OOPL and I think it can do the same work. So, for my needs, is 'open_uri' the best choice (although it is more complicated of 'always_verify_ssl_certificates' gem)? If so, can someone help me using that (with an example, if possible) because I have not found good guides about?

• DotNetOpenAuth DesktopConsumer with GData help needed

• Java: where should I put anonymous listener logic code?

  - by tulskiy

  Hi, we had a debate at work about what is the best practice for using listeners in java: whether listener logic should stay in the anonymous class, or it should be in a separate method, for example: button.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { // code here } }); or button.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { buttonPressed(); } }); private void buttonPressed() { // code here } which is the recommended way in terms of readability and maintainability? I prefer to keep the code inside the listener and only if gets too large, make it an inner class. Here I assume that the code is not duplicated anywhere else. Thank you.
