• In the context of an asp.net website, what's the most efficient way to check whether a User has acce

  - by scaramouch

  I have a webpage that you pass in an id parameter (via a querystring), which it then uses to fetch data from a database. Typically, a user would navigate to this page from another page that lists only those records that the user has access to. However, if they go directly to the page by typing in the URL in the Address Bar, they can effectively view any record they like. Eg. If they were to type something like http://localhost/TestSite/ClientAdmin/ManageLocation.aspx?LocationID=5 into their Address Bar, they can access the database record with the LocationID equal to five - even though they shouldn't have access to it. Now, I could solve this by doing a database check every time the page is loaded to see whether the current user has access to the record they're trying to view. However this doesn't seem very efficient given that in most cases a user won't be trying to access a record that isn't theirs. Does anyone have a better suggestion? Thanks.

• which one consume less resources? opening text file or make an sql query,both a thousand times ?

  - by imin

  hi I've a php website which displays recipes www.trymasak.my, to be exact. The recipes being displayed at the index page is updated about once a day. To get the latest recipes, I just use a mysql query which is something like "select recipe_name, page_views, image from table order by last_updated". So if I got 10000 visitors a day, obviously the query would be made 10000 times a day. A friend told me a better way (in terms of reducing server load) is when I update the recipes, I just put in the latest recipe details (names,images etc) into a text file, and make my page instead of querying a same query for 10,000 times, just get the data from the text file. Is his suggestion really better? If yes, which is the best php command should I use to open, read and close the text file? thanks

• Method for demonstrating iPad application in online meetings

  - by competent_tech

  We have recently developed an iPad application and now need to start demonstrating it to customers and prospects as part of our overall product suite during webinars. As part of our Agile methodology, we also need to periodically review the application with key customers without having to distribute it since the application is not a standalone application and requires a connection to web services installed at each customer site. We have searched high and low for any solution that doesn't involve rooting the device but have been unable to find one. The most common suggestion seems to be to point a webcam at the device, but that comes across as very unprofessional. I know that there are VGA out adapters that can be plugged into the iPad and we have used these to present through a projector when the customer is physically present, but this is a relatively rare occurrence. Perhaps there are solutions that we are unaware of that can be used to send VGA output back into a desktop device for screen sharing?

• How to set up two models having a has_many association with each other

  - by daz13

  I'm looking for a suggestion on how to set up two models, Teacher and Subject. A Teacher can have many Subjects, and a Subject can have many Teachers. Another thing to consider in the relationship between the two models is that a Teacher can create a Subject and add other Teachers to the Subject. I think I'm solid on the basics of the set up for each model: for teacher.rb: has_many :subjects for subject.rb: has_many :teachers and the teachers table should have a subject_id column and the subject table should have a teacher_id column. What I'm not sure about is how to set up the views (and corresponding controller methods) to allow the addition of a Teacher to a Subject. Any suggestions (or links to examples) are greatly appreciated. I haven't been able to find anything on this exact case.

• Can I define which characters are allowed to 'break' a word?

  - by zneak

  Hey guys, I'm showing up veeeery long URLs in my Safari extension. Obviously, they can't fit on a single line. Currently, word breaking rules make it so most URLs are on two lines: the first one is rather short and ends with the ? symbol, and the other is ridiculously long and contains all the rest of the GET parameters. I'd like to make it so words also break on the & symbol, without screwing up copy-paste if possible. I've tried to replace every & with &\u00ad (& + the soft hyphen character), but it's kind of weird to see the hyphen after the & when there really isn't any in the URL. I thought there was something in store with CSS3 for that kind of problem, but I can't find it. Any suggestion welcome, as long as it works with Safari.

• sum of timespans

  - by frenchie

  I have a collection of objects that include a timespan variable: MyObject { TimeSpan TheDuration {get;set;} } I want to use linq to sum those times. Of course, (from r in MyCollection select r.TheDuration).Sum(); doesn't work! I'm thinking of changing the datatype of TheDuration to an int and then summing it and converting the sum to a TimeSpan. That'll be messy because each TheDuration in my collection is used in as a timespan somewhere else. Any suggestion on this summation?

• How to distribute the chance to display each SWF evenly among banner collection?

  - by Michael Mao

  Hi all: I am working on The ausdcf.org to try adding several banner ads in swf format to the top. Everything starts to work, but I've got several questions that need your help: The client chose not to go with Google AdManager, but prefer a "minimal approach" to do this task. What I am trying to do is sort of "mimicking" the way Google AdManager does for banners, that is, to split the chance of each particular swf to be shown to the visitor evenly among the banner collection. Definitely I can add some jQuery code to do this from client-side, a random number generator and if-else statement would work - just $.load() it! However, what if I'd like to make sure those disabled Javascript (is there any now btw?) still be able to see different swfs in each visit. Any suggestion on how to approach this? Many thanks in advance.

• NullPointerException when accessing image files in a .jar file

  - by user548240

  Hi, I have pretty much tried everything but still have this same problem. I have the following setup: I have a images.jar containing a folder called 'images' in which there are multiple image files. I add images.jar to the java build path of the project in eclipse, and i've been trying to use the following code to access the individual images in the jar: URL url = this.getClass().getResource("images/a.png"); ImageIcon icon = new ImageIcon (url); Unfortunately, the URL object is always NULL. I don't think this has anything to do with where I put images.jar file as it is added to the classpath in eclipse. I have also tried using the path '/images/a.png', but still the same problem. Any suggestion would be extremely welcome! Thanks.

• How can I filter out the "My Computer"-option in a SWT DirectoryDialog?

  - by Superfisi

  Hello *, in our Eclipse RCP application running on Windows XP we use a DirectoryDialog, in which the user should... ahmm... choose a directory! :D The problem is: If the user selects the "My Computer"-option (in German Windows "Arbeitsplatz") the Dialog returns null. The DirectoryDialog provides a method setFilterPath(String path) in which I put the File.pathSeparatorChar (to remain OS-independant). My suggestion was that if there has to be a file separator in the directory the "My Computer"-option would be ignored cause it is null - for example the "OK"-button would be greyed out or sth. like that... but it is also valid to klick "OK". Any suggestions from your side? :D Thanks in advance! Alex

• Mapview on tablet: How can I center the map with an offset?

  - by Waza_Be

  Hint: Here is a similar post with HTML. In the current tablet implementation of my app, I have a fullscreen MapView with some informations displayed in a RelativeLayout on a left panel, like this: (My layout is quite trivial, and I guess there is no need to post it for readability) The problem comes when I want to center the map on a specific point... If I use this code: mapController.setCenter(point); I will of course get the point in the center of the screen and not in the center of the empty area. I have really no idea where I could start to turn the offset of the left panel into map coordinates... Thanks a lot for any help or suggestion

• [Java] Listening for TCP and UDP requests on the same port

  - by user339328

  I am writing a Client/Server set of programs Depending on the operation requested by the client, I use make TCP or UDP request. Implementing the client side is straight-forward, since I can easily open connection with any protocol and send the request to the server-side. On the servers-side, on the other hand, I would like to listen both for UDP and TCP connections on the same port. Moreover, I like the the server to open new thread for each connection request. I have adopted the approach explained in: link text I have extended this code sample by creating new threads for each TCP/UDP request. This works correctly if I use TCP only, but it fails when I attempt to make UDP bindings. Please give me any suggestion how can I correct this. tnx

• JQuery-code on different content pages

  - by Ockonal

  Hello, I have a site with menu, which reloads content. Content is dynamically loadable, using ajax and php-script. At different content pages I need in different jquery-plugins. But If I'm writing including need plugin directly in some content page, I get a big lags during loading. So, now I'm includgin all plugins into main page... And it's not the best idea... Any suggestion? UPD: I have a div with content. Content is shown with effects (rolling up/down). When part of menu is clicked, I'm sending ajax-responce to the php script, which reads need text from database and returns it to the main page, from which I sent the responce. Than I'm pasting that content into a div and roll id down. So I'll include jquery-plugins in content pages, the animation of rolling will'nt be normal.

• ASP.NET permissions issues

  - by Paul

  Im using Windows Server 2008, IIS7, .NET 4 and when I use the FileUpload control to save a file to a directory I get : Access to the path 'C:\xxx\Websites\CMS\Admin\test' is denied. I have given the test folder full control permissions for NETWORK SERVICE but it makes no difference. I have given full control to the Everyone user but makes no difference. It might have something to do with the fact that up in the CMS folder there is a MVC web application and in the CMS\Admin folder there is a web forms web application. It is the web forms web application that is trying to upload the file and getting the permissions error. Can anyone offer a suggestion.

• Finding Most Recent Order for a Particular Item

  - by visitor

  I'm trying to write a SQL Query for DB2 Version 8 which retrieves the most recent order of a specific part for a list of users. The query receives a parameter which contains a list of customerId numbers and the partId number. For example, Order Table OrderID PartID CustomerID OrderTime I initially wanted to try: Select * from Order where OrderId = ( Select orderId from Order where partId = #requestedPartId# and customerId = #customerId# Order by orderTime desc fetch first 1 rows only ); The problem with the above query is that it only works for a single user and my query needs to include multiple users. Does anyone have a suggestion about how I could expand the above query to work for multiple users? If I remove my "fetch first 1 rows only," then it will return all rows instead of the most recent. I also tried using Max(OrderTime), but I couldn't find a way to return the OrderId from the sub-select. Thanks! Note: DB2 Version 8 does not support the SQL "TOP" function.

• Building a jar to be used in an eclipse PDE?

  - by tul

  I have written an application that use a third party library. I have then packaged this as an executable jar using the maven-assembly-plugin (producing a jar with all dependencies including some of the third-party jars). Next I need to add this jar to a PDE project so it can be launched from eclipse. But to make this work I need to add some of the thirs-party dependencies to my PDE project which is already located in the packaged jar. So I get duplicated dependencies. Any ideas on how to avoid this? Or suggestion to documentation that describes how this is done properly?

• .BAT Switches Parsing

  - by giiYanJ

  Erm.. I'm working with a switches parsing in BAT files, which goes like this: <commands> -a -b -x -y -z -u abc ...... The user may input a lot of switch, or none. So I used looped shift to make parsing infinite switches possible: :loop IF "%1"=="-a" ... SHIFT GOTO loop But when the script ends, I always get cmd executing the switches and showing up error like '-n' is not recognized as an internal... So, someone got any idea? Thanks a lot... P/S: Make solution sticks with BAT script if possible as using other language may cause dependencies problem as this script is aimed on ANY computer with Windows. Finally, thanks again =) EDIT: Tried shf301 suggestion, i found out that I used DEL %0 to delete itself but it seems the %0 is shifted into the arguments because of the SHIFT command.
