  • ASP.NET MVC Routes

    - by MVCDummy09
    Can I see one example that would make this piece of code compile? public IEnumerable<RouteBase> Routes { get { return new List<Route>() { new Route(...) } } } What would you do if RouteCollection.MapRoute() didn't exist? I'm trying to put my Controller in charge of mapping routes, not Global.asax.cs. public IEnumerable<RouteBase> Routes is a member of my Controller. If the Controller is responsible for a Route, it's a bad idea to decouple the Route by using routes.MapRoute() in Global.asax.cs.

  • Temp file that exists only in RAM?

    - by Auraomega
    I'm trying to write an encrpytion using the OTP method. In keeping with the security theories I need the plain text documents to be stored only in memory and never ever written to a physical drive. The tmpnam command appears to be what I need, but from what I can see it saves the file on the disk and not the RAM. Using C++ is there any (platform independent) method that allows a file to exist only in RAM? I would like to avoid using a RAM disk method if possible. Thanks Edit: Thanks, its more just a learning thing for me, I'm new to encryption and just working through different methods, I don't actually plan on using many of them (esspecially OTP due to doubling the original file size because of the "pad"). If I'm totally honest, I'm a Linux user so ditching Windows wouldn't be too bad, I'm looking into using RAM disks for now as FUSE seems a bit overkill for a "learning" thing.

  • privmsg system db schema

    - by Bartek
    I'm making a PM-system on my site. And I want to know ultimate db schema. I have always just used only 1 table. But my users have started complained that the messages in their outbox suddently dissapers =D Thats because if the other users deletes it, the one who sent it wont see it to. So im thinking of making another table with the same fields So im thinking something like this: privmsgs id | to | from | subject | message | date -- -- ---- ------- ------- ---- 1 76 893 blabla. blabla. 20100404 sent_msgs id | to | from | subject | message | date -- -- ---- ------- ------- ---- 1 76 893 blabla. blabla. 20100404 Whatya think? Sorry for my bad english

  • iPhone modal view inside another modal view?

    - by Rick
    My App uses a modal view when users add a new foo. The user selects a foo type using this modal view. Depending on what type is selected, the user needs to be asked for more information. I'd like to use another modal view to ask for this extra information. I've tried to create the new modal view like the first one (which works great) and it leads to stack overflow/“Loading Stack Frames” error in Xcode. Am I going about this in completely the wrong way i.e. is this just a really bad idea? Should I rethink the UI itself? UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:addController]; [self presentModalViewController:navigationController animated:YES];

  • Are database triggers evil?

    - by WW
    Are database triggers a bad idea? In my experience they are evil, because they can result in surprising side effects, and are difficult to debug (especially when one trigger fires another). Often developers do not even think of looking if there is a trigger. On the other hand, it seems like if you have logic that must occur evertime a new FOO is created in the database then the most foolproof place to put it is an insert trigger on the FOO table. The only time we're using triggers is for really simple things like setting the ModifiedDate.

  • What ports does Advantage Database Server need?

    - by asherber
    I have an application which uses ADS and I am attempting to deploy it in a Windows network environment with a rather restrictive firewall. I am having a problem configuring firewall ports appropriately. ADS lives on \server, and it's listening on port 1234. When \client tries to connect to \server\tables, I get Error 6420 (Discovery process failed). When \client tries to connect to \server:1234\tables, I get error 6097, bad IP address specified in the connection path. \server is pingable from \client, and I can telnet to \server:1234. If I try to connect from a client machine inside the firewall, either connection path works fine. It seems there must be something else I need to open in the firewall. Any ideas? Thanks, Aaron.

  • Volume group disappeared, LVs still available

    - by Ben
    I've run into an issue with my KVM host which runs VMs on a LVM volume. As of last night the logical volumes are no longer seen as such (I can't create snapshots of them even though I have been for months now). Running any scans all result in nothing being found: [root@apollo ~]# pvscan No matching physical volumes found [root@apollo ~]# vgscan Reading all physical volumes. This may take a while... No volume groups found root@apollo ~]# lvscan No volume groups found If I try restoring the VG conf backup from /etc/lvm/backups/vg0 I get the following error: [root@apollo ~]# vgcfgrestore -f /etc/lvm/backup/vg0 vg0 Couldn't find device with uuid 20zG25-H8MU-UQPf-u0hD-NftW-ngsC-mG63dt.

  • How to improve my LDAP schema?

    - by asmaier
    Hello, I have a OpenLDAP Database and it holds some project objects that look like dn: cn=Proj1,ou=Project,ou=ua,dc=org cn: Proj1 objectClass: top objectClass: posixGroup member: 001ag member: 002ag System: ABEL System: PCx Budget: ABEL:1000000:0.3 Budget: PCx:300000:0.3 One can see that the Budget attribute is a ":"-separated string, where the first part holds the name of the system the budget is for, the second part holds some budget (which may change every month) and the last entry is a conversion factor for the budget of that system. Seeing this, I thought this is bad database design, since attribute values should always be atomic. But how can I improve that in LDAP, so that I can do a direct ldapsearch or a direct ldapmodify of the budget of System "ABEL" instead of writing a script, that will have to parse and split the ":"-separated string?

  • Why is it preferable to call a static method statically from within an instance of the method's clas

    - by javanix
    If I create an instance of a class in Java, why is it preferable to call a static method of that same class statically, rather than using this.method()? I get a warning from Eclipse when I try to call static method staticMethod() from within the custom class's constructor via this.staticMethod(). public MyClass() { this.staticMethod(); } vs public MyClass() { MyClass.staticMethod(); } Can anyone explain why this is a bad thing to do? It seems to me like the compiler should already have allocated an instance of the object, so statically allocating memory would be unneeded overhead.

  • Best way to implement a Rest API with PHP on Wamp web server

    - by DomingoSL
    Hello, i own a web server running windows (WAMP). I want to know the best way to implement a Rest API (a very simple one) in order to let a user do something. Diagram flow: I have programming skills, in fact, i developed some time ago a web server in VB6 who process the querys and when it find the command (http:/serverIP/webform.php?cmd=run&item=any) it do something, but know i really want to develop a solution using the WAMP server. Some people consider the solution of executing a exe when a command is detected a bad solution for security issues, but this specific proyect i have is for the use of only some people (trusted people) who dont have intentions of hacking the server. So, what do you think? Remember: Its not a public API, its for some people and some programs who will use the API Its a very simple one, only one command using POST or GET. Thanks

  • NHibernate transaction management in ASP.NET MVC - how should it be done?

    - by adrin
    I am writing a simple ASP.NET MVC using session per request and transaction per request patterns (custom HttpModule). It seems to work properly, but.. the performance is terrible (a simple page loads ~7 seconds). For every http request, graphical resources incuding (all images on the site) a transaction is created and that seems to delay the loading times (without the transactions loading times per one image are ~1-10 ms with transactions they are over 1 second). What is the proper way to manage transactions in ASP.NET MVC + NH stack? When i've put all transactions into my repository methods, for some obscure reasons I got 'implicit transactions' warning in NHProf (the SQL statements were executed outside transaction, even that in code session.Save()/Update()/etc methods were invoked within transaction 'using' scope and before transaction.Commit() call) BTW are implicit transactions really bad?

  • Dispelling the UIImage imageNamed: FUD

    - by Roger Nolan
    I see a lot of people saying imageNamed is bad but equal numbers of people saying the performance is good - especially when rendering UITableViews. See this SO question for example or this article on iPhoneDeveloperTips.com UIImage's imageNamed method used to leak so it was best avoided but has been fixed in recent releases. I'd like to understand the caching algorithm better in order to make a reasoned decision about where I can trust the system to cache my images and where I need to go the extra mile and do it myself. My current basic understanding is that it's a simple NSMutableDictionary of UIImages referenced by filename. It gets bigger and when memory runs out it gets a lot smaller. For example, does anyone know for sure that the image cache behind imageNamed does not respond to didReceiveMemoryWarning? It seems unlikely that Apple would not do this. If you have any insight into the caching algorithm, please post it here.

  • Logging which is the best way

    - by Tony
    Hi People who talk about loggers here never talke about EventLog, I think this is good for windows system. Is it reliable, or I found it dead in some bad morning? Why not logging everything at SQLServer, I am creating E-Commerce website, if SQL server down the website will be down anyway. but I am worry about temporally connection failure, what do u think? Why everyone like files, it can be in great size, too big to handle, or maybe I will create another file when a file is too big, and I can create a file with a date. Some one tried MS Enterprise library? talk to me about it. Thanks

  • Methods for ensuring security between users in multi-user applications

    - by Emilio
    I'm writing a multiuser application (.NET - C#) in which each user's data is separated from the others and there is no data that's common between users. It's critical to ensure that no user has access to another user's data. What are some approaches for implementing security at the database level and/or in the application architecture to to accomplish this? For example (and this is totally made up - I'm not suggesting it's a good or bad approach) including a userID column in all data tables might be an approach. I'm developing the app in C# (asp.net) and SQL Server 2008. I'm looking for options that are are either native in the tools I'm using or general patterns.

  • Verify my form workflow

    - by Shackrock
    I have a form, with some sensitive info (CC numbers). My work flow is: One page to take all form items Upon submission, values are validated. If all is well, all data is stored in a session variable, and the page reloads and displays this info from the session variable. If everything is ok on the review page, the user clicks submit and the session variable is sent to another form for processing (sending payment). Upon success, the session is destroyed. Upon failure (bad CC number, for example) - the user is sent back to the form, with all of the fields filled in just like before, so that they can check for errors and try again (session is NOT destroyed). Does anyone see anything wrong with this, from a security or best practices stand point? UPDATE I'm thinking I can get rid of a step - storing the info in a session EVER. Just have a one page checkout, no review page... makes sense.

  • React to change on a static property

    - by Stiggler
    I'm re-writing an MXML item renderer in pure AS. A problem I can't seem to get past is how to have each item renderer react to a change on a static property on the item renderer class. In the MXML version, I have the following binding set up on the item renderer: instanceProperty={callInstanceFunction(ItemRenderer.staticProperty)} What would be the equivalent way of setting this up in AS (using BindingUtils, I assume)? UPDATE: So I thought the following wasn't working, but it appears as if Flex is suppressing errors thrown in the instanceFunction, making it appear as if the binding itself is bad. BindingUtils.bindSetter(instanceFunction, ItemRenderer, "staticProperty"); However, when instanceFunction is called, already initialized variables on the given instance are all null, which was the cause of the errors referenced above. Any ideas why this is?

  • Fix/Bypass "Cannot connect to the real website-blocked" error in Google Chrome with OpenDNS blocking

    - by George H
    I have a large problem with Chrome in my organisation. I use DNS to manage web site blocking, for sites which are not appropriate and are potentially a risk to the organisation where I do this. I only want to use Chrome over the network, as Internet Explorer has compatibility problems with some sites that we use (We cannot change this either or use different sites). Therefore using internet explorer is not a solution. I do not want to install a different browser, for multiple reasons. Mainly because of the difficulty of rewriting the customised add-ons that we use. However, recently, I have had lots of problems with Chrome SSL Errors. I cannot use my custom OpenDNS block pages, which uses the contact form to request an unblocking. Chrome often blocks OpenDNS for sites (a good example is Facebook) that request HTTPS. Some sites like https://internetbadguys.com (OpenDNS example) This means that chrome refuses to load the blocking page, explaining that the site is blocked. Instead they often call IT support, but they want a solution, as they are sick of getting lots of SSL errors. I have tried looking into ways to turning this off. I have tried: Typing "proceed". That didn't work. Typing "proceed", pressing enter. Didn't work I cannot find phishing and anti-malware any more in Chrome, from the internet guides. Not using HTTPS. However there is an automatic redirect to HTTPS on most sites. Therefore the error keeps coming up. Checking my clocks. They were correct. Does anyone have an idea on how to disabling, bypassing or working around this "feature"? EDIT: This is an example what I am talking about - I found that on google images. I do not block google. EDIT 2: My clocks are correct. I cannot stop using OpenDNS either. EDIT 3: My question is: How do I stop chrome from refusing to load pages that are blocked by OpenDNS, where the server has explicitly requested HTTPS.

  • How to add a another value to a key in python

    - by Nanowatt
    First I'm sorry this might be a dumb question but I'm trying to self learn python and I can't find the answer to my question. I want to make a phonebook and I need to add an email to an already existing name. That name has already a phone number attached. I have this first code: phonebook = {} phonebook ['ana'] = '12345' phonebook ['maria']= '23456' , '[email protected]' def add_contact(): name = raw_input ("Please enter a name:") number = raw_input ("Please enter a number:") phonebook[name] = number Then I wanted to add an email to the name "ana" for example: ana: 12345, [email protected]. I created this code but instead of addend a new value (the email), it just changes the old one, removing the number: def add_email(): name = raw_input("Please enter a name:") email = raw_input("Please enter an email:") phonebook[name] = email I tried .append() too but it didn't work. Can you help me? And I'm sorry if the code is bad, I'm just trying to learn and I'm a bit noob yet :)

  • In LaTeX prefer figures on text-heavy pages.

    - by bjarkef
    Hi LaTeX seems to have a preference for placing figures together on a page, and placing surrounding text on a separate page. Can I somehow change that balance a bit, as I prefer figures to break up the text to avoid too black text-heavy pages. Example: \section{Some section} [Half a page of text] \begin{figure} [...] \caption{Figure text 1} \end{figure} [Half a page of text] \begin{figure} [...] \caption{Figure text 2} \end{figure} [More text] So what LaTeX usually does is to stack the two half pages of text on a single page, and the figures on the following page. I believe this really gives a bad balance, and bores the reader. So can I change that somehow? I know about postfixing the \begin{figure} with [ht!], but often it does not really matter. I would like to configure the balancing algorithms in LaTeX to naturally prefer pages with combined figures and text.

  • Freelancer's problem and legal actions

    - by user198003
    Hi, Last year, I worked as a free lancer on one project. Unfortunately, person I worked for, decided that he is not happy about my work, and he decided to fired me. After 7 months, he called me, and ask to me return "his" money. In any other case, he will sue me. His version is that I have to give him 1500 euros, but my version is that he own me another 1500. I have no contract, only emails and Excel file with counted hours. What do I have to do? I don't want to give him back 1500, because it was my work, and his bad management. Also, I do not want my 1500, because I think it's not fair from my side. What should I do?

  • Unkillable console windows

    - by rep_movsd
    I'm developing an OpenGL based 2d simulation with GLUT under Visual C++ 2008, sometimes when I have an assert() or unhandled exception and break into the debugger, the GLUT display window closes, but the console window remains open.They just cant be killed!!! They do not show up with Task manager, Process Explorer or any other tool, I cannot find the window handle using the Spy++ tool either. Worst thing is they prevent my system (Windows XP) from shutting down, I have to manually poweroff (and of course I have to run chkdsk on my drives and invariably it finds and fixes minor errors after bad shutdowns) Has anyone come across such an issue?

  • Java Memory Management

    - by Tara Singh
    I am designing a client-server chat application in Java. This is a secure application where the messages are exchanged using cryptographic algorithms. I have one server and it can support many clients. My problem is that when one client logs on the server it works fine, but when another user logs into the system, the server starts giving me bad padding exceptions for the encrypted text. I am not able to figure out the problem, according to my logic, when new connection request to server is made, the server creates a thread for listening to the client. Is it possible that once the instance of thread class is created, it does all the processing correctly for the first client, but not for the second client because the variables in server listener thread class already have some previous value, and thus the encrypted text is not decrypted properly? Please advise how I can make this process more robust so that the number of clients does not affect how well the server functions.

  • Why does asp.net mvc form submits itself on button clicks when javascript function error?

    hi guys, i'm new to the asp.net mvc, and while working on this, i used very basic asp.net mvc stuff like beginform, etc. i used a lot of jquery codes this round for client side validation, ajax data retrieval, and other gui works. and i used a combinations of html inputs buttons, etc and the asp.net mvc type of controls. what i noticed is that whenever i click on a button control, which sometimes are tied to either jquery oclick events, when there's a javascript error, the page will just go on and submit. why is this happening and what am i missing here? my bad for the dumb questions.. thanks
