  • Run both Authorize Filter and Action Filter on unauthenticated ASP.NET MVC request

    - by Bryan Migliorisi
    I have decorated my base controller with a couple of action filters. They work fine. One of those filters sets up the request - does things like set the culture based on the domain, etc. I also have a handful of actions that require authorization using the Authorize attribute. My problem is that when an user attempts to request a page they are not authorized to access, the authorization filter kicks in and redirects them to a page telling them that they cannot vie the page. The issue is that the action filters never run so the culture and other request data is never set. This effectively causes language to be wrong in the view and other data to be missing. I know that authorization filters run first but my question is this: How can I design this such that I can ensure that certain methods are always run before the view is returned, regardless of the authorization. Hope that makes sense.

  • Facebook Application Tab URL

    - by Paul
    I have a facebook application that can be added to fan pages as a tab. The application requires that users are authenticated in order to use it. This can be accomplished by using requirelogin=1 in a link which is visible only to users who have NOT added the application. This part works fine. However, after the user has given my application permission from the dhtml pop up that requirelogin opens, I want the tab to reload. In order to do that, I need the full URL to be included in the link as follows: <a href="http://www.facebook.com/pages/PAGE_NAME/PAGE_ID?v=app_APP_ID" requirelogin=1>Authorize</a> I cannot figure out how to get the full url or, at least, the PAGE_NAME to build this url dynamically. Seems like the app should be able to know where it is without any special permissions.

  • PHP Flush: How Often and Best Practises

    - by Cory Dee
    I just finished reading this post: http://developer.yahoo.com/performance/rules.html#flush and have already implemented a flush after the top portion of my page loads (head, css, top banner/search/nav). Is there any performance hit in flushing? Is there such a thing as doing it too often? What are the best practices? If I am going to hit an external API for data, would it make sense to flush before hand so that the user isn't waiting on that data to come back, and can at least get some data before hand? Thanks to everyone in advance.

  • How can I define custom 'contentGroups' in a custom Flex 4 component?

    - by swidnikk
    The spark panel component for example can be written like this And its skin file will handle layout of the contentGroup, controlBarGroup, and titleDisplay. Notice, however that the contentGroup is doesn't appear in the code above and that the controlBarGroup accepts child mxml components. Now say I want to create a custom component that defines various required and non-required skinparts, such as 'headerGroup', 'navigationGroup', and 'accountPreferencesGroup'. I'd like to write this custom component like this The motivation here is that I can now create a couple different skin files to change the look and layout of those subgroups. Reading source of the spark panel, there are some calls within the mx_internal namespace such as getMXMLContent() which is a method of the spark group component, but which I have no access to. Does the description above make sense? How can I create custom 'contentGroups' in my custom Flex4 component that can use nested mxml child components? Should I approach this a different way?

  • SQL - .NET - SqlParameters - AddWithValue - Are there any negative performance implications when Par

    - by hamlin11
    http://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlparametercollection.addwithvalue.aspx I'm used to adding sql parameters to a sqlCommand using the add() function. This allows me to specify the type of the sqlParameter, but it requires another line to set the value. It's nice to use the AddWithValue function, but it skips the "specify the parameter type" step. I'm guessing this causes the parameters to be sent over as strings contained within single quotes (''), but I'm not sure. Is this the case, and does this cause significantly slower performance of the stored procedures? Note: I understand that it is nice to validate user data on the .NET side of things by specifying the data type for params -- I'm only concerned about reflection-type overhead of AddWithValue either on the .NET or SQL side.

  • Is it possible to reset NSURLConnection after providing credentials?

    - by John
    I am calling a REST service that requires basic auth and I respond to the didReceiveAuthenticationChallenge delegate OK NSURLCredential *credential = [[NSURLCredential alloc] initWithUser:self.user password:self.password persistence:NSURLCredentialPersistenceForSession]; [[challenge sender] useCredential:credential forAuthenticationChallenge:challenge]; [credential release]; The Credentials are valid for the Session but I would like for my App to be able to switch between servers and therefore need to "reset" the Session so it asks again for a challenge. I can of course try the option of not storing the credentials for the Session and supply them for each call but this does not seem like a good idea. Any ideas would be appreciated!

  • Check ReturnUrl is valid before redirecting

    - by Josh
    I'm using ASP.NET Membership and Form Authentication and before redirecting to the returnURL I wanted to validate it. For those unfamiliar with the workflow, basically if you request a page that requires that you are authenticated, you are redirected to a login page. In the URL string you'll see a parameter called returnURL, e.g. http://example.com/login.aspx?ReturnUrl=%2fprotected%2fdefault.aspx Whether you use this in a redirect such as Response.Redirect(returnURL) or indirectly through the FormsAuthentication.RedirectFromLoginPage method, it passes without validating returnURL. FormsAuthentication.RedirectFromLoginPage does have a security check that it is isn't leaving the domain, but that still doesn't stop someone from putting enough random characters to cause an error. I tried using System.IO.File.Exists(Server.MapPath(returnURL)) but given enough illegal characters it cause Server.MapPath to error. Note: URLEncoding doesn't work because we are not cleaning a parameter, but the primary URL. Any other suggestions for validating or cleaning the returnURL value?

  • Win CE 6.0 client using WCF Services

    - by Sean
    We have a Win CE 6.0 device that is required to consume services that will be provided using WCF. We are attempting to reduce bandwidth usage as much as possible and with a simple test we have found that using UDP instead of HTTP saved significant data usage. I understand there are limitations regarding WCF on .NET Compact Framework 3.5 devices and was curious what people thought would be the appropriate way forward. Would it make sense to develop a custom UDP binding, and would that work for both sides? Any feedback would be appreciated. Thanks.

  • Show soft keyboard when Activity starts

    - by Al
    I have 2 activities, A and B. When A starts, it checks for a condition and if true, it calls startActivityForResult() to start B. B only takes text input so it makes sense for the soft keyboard to automatically pop up when B start. When the activity starts, the EditText already has focus and it ready for input. The problem is that the keyboard never shows up, even with windowSoftInputMode="stateAlwaysVisible" set in the manifest under the <activity> tag for B. I also tried with the value set to stateVisible. Since it doesn't show up automatically, I have to tap the EditText to make it show. Anyone know what the solution might be?

  • Oracle analytic functions for "the attribute from the row with the max date"

    - by tpdi
    I'm refactoring a colleague's code, and I have several cases where he's using a cursor to get "the latest row that matches some predicate": His technique is to write the join as a cursor, order it by the date field descending, open the cursor, get the first row, and close the cursor. This requires calling a cursor for each row of the result set that drives this, which is costly for many rows. I'd prefer to be able to join, but what something cheaper than a correlated subquery: select a.id_shared_by_several_rows, a.foo from audit_trail a where a.entry_date = (select max(a.entry_date) from audit_trail b where b.id_shared_by_several_rows = a.id_shared_by_several_rows ); I'm guessing that since this is a common need, there's an Oracle analytic function that does this?

  • Dependency Injection with Custom Membership Provider

    - by alastairs
    I have an ASP.NET MVC web application that implements a custom membership provider. The custom membership provider takes a UserRepository to its constructor that provides an interface between the membership provider and NHibernate. The UserRepository is provided by the Ninject IoC container. Obviously, however, this doesn't work when the provider is instantiated by .NET: the parameterless constructor does not have a UserRepository and cannot create one (the UserRepository requires an NHibernate session be passed to its constructor), which then means that the provider cannot access its data store. How can I resolve my object dependency? It's probably worth noting that this is an existing application that has been retrofitted with Ninject. Previously I used parameterless constructors that were able to create their required dependencies in conjunction with the parametered constructors to assist unit testing. Any thoughts, or have I built myself into a corner here?

  • Microsoft flexgrid Control : Run-time error '438' Object doesnt support this property or method

    - by Dan
    I am maintaining a legacy Microsoft Access application that is using the Microsoft Flexgrid 6.0. It recently started causing the following error: Run-time error '438' Object doesn't support this property or method People say that this error can be caused by the KB960715 security update being applied, which sets killbits on various ActiveX control methods which were deemed a security risk. But this or no other security update has been applied recently. Others say that installing Microsoft Visual Basic 6.0 Service Pack 6 Cumulative Update will update the flex grid. This requires VB6 to be installed as a prerequisite so I installed that on my PC and then the update, and retrieved the updated MsFlxGrd.ocx file(Version: 6.1.98.12) and copied to the application machine, but the error still prevails. Someone here says you can disable the killbit in the registry. But there are afew hundred nodes in the location they suggest, none of which has the same guid as the one they point out. Any ideas?

  • Having problems building Cairo on x64 CentOS

    - by Vnuk
    I've done this many times on 32 bit CentOS and everything went ok without a hitch. But now, on x64 CentOS, I can't get cairo to find pixman. Pixman 0.18.0 is installed in /usr/local/lib (which I believe is the usual location). Configure for Cairo 1.8.10 can't find it: checking for cairo's image surface backend feature... checking for pixman... no no checking whether cairo's image surface backend feature could be enabled... no (requires pixman-1 >= 0.12.0 http://cairographics.org/releases/) configure: error: mandatory image surface backend feature could not be enabled I've tried setting environment variable pixman_LIBS=/usr/local/lib but wihtout any luck. Any idea what is going wrong? Is it possible for me to see where is cairo's configure looking for pixman? Search paths or something like that?

  • Can't get SubSonic insert to work

    - by Darkwater23
    I'm trying to insert a record into a table without using the SubSonic object in a VB.Net Windows app. (It will take too long to explain why.) Dim q As New SubSonic.Query("tablename") q.QueryType = SubSonic.QueryType.Insert q.AddUpdateSetting("Description", txtDescription.Text) q.Execute() This just updates all the rows in the table. I read in one post that instead of AddUpdateSetting, I should use AddWhere, but that didn't make any sense to me. I don't need a where clause at all. Searching for all:QueryType.Insert at subsonicproject.com didn't return anything (which I thought was weird). Can anyone tell me how to fix this query? Thanks!

  • Python (pdb) - Queueing up commands to execute

    - by kpatelPro
    I am implementing a "breakpoint" system for use in my Python development that will allow me to call a function that, in essence, calls pdb.set_trace(); Some of the functionality that I would like to implement requires me to control pdb from code while I am within a set_trace context. Example: disableList = [] def breakpoint(name=None): def d(): disableList.append(name) #**** #issue 'run' command to pdb so user #does not have to type 'c' #**** if name in disableList: return print "Use d() to disable breakpoint, 'c' to continue" pdb.set_trace(); In the above example, how do I implement the comments demarked by the #**** ? In other parts of this system, I would like to issue an 'up' command, or two sequential 'up' commands without leaving the pdb session (so the user ends up at a pdb prompt but up two levels on the call stack. Thanks!

  • Workflow Foundation 4 WorkflowServiceHost Message Correlation

    - by Lygpt
    I have 2 methods on a workflow service hosted in WorkflowServiceHost. The first method is called and starts the regular workflow sequence - talking to other web services, database work etc but on some occassions will pause and persist to db (as-in the delay activity) and wait for some human action to take place before continuing. I need my second method to be able to hook into this persisted workflow, change a local variable and then continuing processing. I have looked at message based correlation in workflow but can only seem to find examples where some kind of infinite while loop keeps the workflow instance active so that the second service method call can arrive whilst it's still running. Because my workflow instance will be delayed/persisted, the second service call doesn't seem to get anywhere (I can't have an infinite while loop keeping the workflow instance active). I hope this makes sense - cheers!

  • How to redirect wordpress post links that are using post_id to new url struture of postname

What I did was change links from: http://blog.mydomain.com/articles/123 To: http://blog.mydomain.com/articles/this-is-a-smaple Is there anyway to direct any links linking to the pages ID number to the postname???? The old url structure is still being published throughout our RSS feed on facebook. So I am trying to catch those people that are or maybe clicking on our links on our facebook posts and redirect them to that posts postname url? Does that make sense? Thanks and help would do

  • pchart pie chart legend and graph not correlating

    - by madphp
    Hi, I have ten values in the dataset, numbers 1 - 10 and corresponding values. Some of the values are coming back as zero, so they are not added to the chart, BUT, the legend is still listing 1 - 10. Because theres values missing in the chart, the colour coding is knocked off. ie Item 1, has a value of zero, its passed over in the chart, the colour in the legend is red, Item 2, has a value of 4, the percentage is calculated, and the chart gives it the colour red which is the colour for item 1 in the legend. Hope that makes sense. How can I print the legend just for the values that are displayed in the chart? --Mark

  • Doxygen ignoring inherited functions, when class inherits privately but the functions declared publi

    - by MichaelM
    Sorry for long winded title, this makes a lot more sense with an example. Suppose we have a class A: class A { public: void someFunction(); void someOtherFunction(); }; And another class that privately inherits from A. However, we re-declare one of the inherited functions as public: class B : private A { public: A::someFunction; } When this code is processed by Doxygen, it does not recognise the public declaration of someFunction in class B. Instead, it shows someFunction as a privately inherited function. This is incorrect. Is anybody aware of how to fix this? Cheers

  • SSL Login in iFrame

    - by Karsten
    My UI prototype requires me to show the sites login info all the time. Either I should show the usual username and password textbox or "you are logged in as". The last bit don't have to be secure, as it's only info to the user, nothing I will use server side. But the first part should send secure to the server. It seems that I would have to use https for all pages on the site then. I would like to only use ssl for the things that are required to be secure. One way is putting the login information into a https://../login.aspx and show it on my mainpage as an IFrame. One disadvantage I can see is that the user won't know that https is being used, unless they read the IFrame src in the source code. What do you think?

  • Finding first alphabetic character in a DB2 database field

    - by Paul Alan Taylor
    I'm doing a bit of work which requires me to truncate DB2 character-based fields. Essentially, I need to discard all text which is found at or after the first alphabetic character. e.g. 102048994BLAHBLAHBLAH becomes:- 102048994 In SQL Server, this would be a doddle - PATINDEX would swoop in and save the day. Much celebration would ensue. My problem is that I need to do this in DB2. Worse, the result needs to be used in a join query, also in DB2. I can't find an easy way to do this. Is there a PATINDEX equivalent in DB2? Is there another way to solve this problem? If need be, I'll hardcode 26 chained LOCATE functions to get my result, but if there is a better way, I am all ears.

  • CodeIgniter & Datamapper as frontend, Django Admin as backend, database tables inconsistent

    - by Rasiel
    I created a database for a site i'm doing using Django as the admin backend. However because the server where the site is hosted on, won't be able to support Python, I find myself needing to do the front end in PHP and as such i've decided to use CodeIgniter along with Datamapper to map the models/relationship. However DataMapper requires the tables to be in a specific format for it to work, and Django maps its tables differently, using the App name as the prefix in the table. I've tried using the prefix & join_prefix vars in datamapper but still doesn't map them correctly. Has anyone used a combination of this? and if so how have the fixed the issue of db table names being inconsistent? Is there anything out there that i can use to make them work together?

  • Where is sdl-config installed on MacOS 10.6 (Snow Leopard)

    - by jmglov
    After installing SDL and SDL-devel in MacOS X 10.6 (Snow Leopard), trying to configure some source code that requires SDL yields: checking for sdl-config... no checking for SDL - version >= 1.2.0... no *** The sdl-config script installed by SDL could not be found *** If SDL was installed in PREFIX, make sure PREFIX/bin is in *** your path, or set the SDL_CONFIG environment variable to the *** full path to sdl-config. configure: error: *** SDL version 1.2.0 not found! Does anyone know where to find sdl-config? I guess I can build SDL from source, but why should I have to, when there exist pre-built packages?

  • Convert binary information to regular data type without outside modules in python.

    - by vgm64
    Hello World. I'm tasked with reading a poorly formatted binary file and taking in the variables. Although I need to do it in C++ (ROOT, specifically), I've decided to do it in python because python makes sense to me, but my plan is to get it working in python and then tackle re-writing in in C++, so using easy to use python modules won't get me too far later down the road. Basically, I do this: In [5]: some_value Out[5]: '\x00I' In [6]: ''.join([str(ord(i)) for i in some_value]) Out[6]: '073' In [7]: int(''.join([str(ord(i)) for i in some_value])) Out[7]: 73 And I know there has to be a better way. What do you think?

  • Rails Oauth Desktop Plugins

    - by Ryan
    I am creating a rails application that I also wish to work as a native app on the iPhone and Android. In order to facilitate this, I was thinking about becoming an OAuth provider. Is there a rails OAuth plugin that will work like this, or is there a better solution to protect the API? Note: I have found pelle's OAuth plugin, and it looks very robust, but it looks like it requires a callback URI, which the native apps would not have. Is it possible to just convert this over without much trouble?
