• Pass information back from an iframe?

  - by ThinkBohemian

  Right now i'm building a firefox plugin that duplicates some functionality on my website. It takes in an email address and then returns information to the user. The easiest way to do this in the plugin is to use an Iframe and render that super simple form on my website. All of this works great, but to make the plugin really useful, i would like the plugin to have access to the information that the iframe renders, so it can use it in the current window that the user is in. Is it possible to pass information back through an Iframe in this manner? I know there are quite a few domain access restrictions with Iframes, so any help or insight is appreciated!!

• How to implement User base security not role base in asp.net?

• Size of assosiation in Hibernate criteria.

  - by trnl

  Hello guys. I've faced with a problem when querying with Hibernate Criteria in Grails. Take a look: def visitors = Client.withCriteria{ visits{ use ( TimeCategory ) {between('date',date,date+1.month-1)} } sizeGe("visits",params.from) sizeLe("visits",params.to) fetchMode("visits", FM.JOIN) }; I need only those clients, which has number of visits in month between from and to bounds. But now size* restrictions is being applied to all visits. So if client has one visit in this month, and visit in previous month. And if I set from=2, this client will be in result. But it should not be there. Any help is appreciated. Thanks, Vova.

• Database permissions and ORMs

  - by Jonn

  I've been using .NET's Entity Framework a lot lately and have absolutely no wish to go back to using Stored Procedures. Been shocked though that the company I'm building this project for had a policy where applications were only given accounts that only had permissions to access stored procedures! Apparently, they believe that there's a security risk involved in allowing applications to access the tables/views directly. I don't get this. My first question is, can someone enlighten me as to what kind of security risk applications having direct access to the database may pose? AND If that's the case, are there any other ORM solutions that can provide a workaround to this (I can't think of any logical possibility atm) that would allow me to circumvent the restrictions on the user account to be assigned to me? OR is my understanding that I'd need direct permissions for the tables and views wrong?

• Hibernate, select by id or unique column

  - by Nican

  I am using hibernate for Java, and I want to be able to select users by id or by name from the database. Nice thing about Hibernate is that it caches the result by id, but I seem to be unable to make it cache by name. static Session openSession = Factory.openSession(); public static User GetUser(int Id) { return (User) openSession.get(User.class, new Integer(Id)); } public static User GetUser( String Name ){ return (User) openSession.createCriteria( User.class ). add( Restrictions.eq("username", Name) ). uniqueResult(); } If I use GetUser(1) many times, hibernate will only show that it executed the first time. But every time I use GetUser("user1"), hibernate shows that it is executing a new query to database. What would be the best way to have the string identifier be cached also?

• Temporary files & folders on Windows

  - by GRIGORE-TURBODISEL

  Emulating multithreading by loading a DLL multiple times (it's designed for this). Since LoadLibrary() doesn't really allow it, the DLL copies itself into a temporary file, via GetTempPath() and GetTempFileName(). It's a small file and upon thread destruction it frees the library and deletes the temporary file. Problem now is that the number of threads is configurable (maniacs can pick 50, 100, more) which basically exposes the risk of running unstable, crash and not go through the usual "delete temporary files" routine. Is it okay if I just leave those temporary files to die there? Does the OS usually clean the up by itself? Or should I write an autocleanup routine? If yes, how can I go about saving another temporary file to hold a list with those files, and not hit UAC restrictions or otherwise? Any ideas?

• Python: Data Object or class

  - by arg20

  I enjoy all the python libraries for scraping websites and I am experimenting with BeautifulSoup and IMDB just for fun. As I come from Java, I have some Java-practices incorporated into my programming styles. I am trying to get the info of a certain movie, I can either create a Movie class or just use a dictionary with keys for the attributes. My question is, should I just use dictionaries when a class will only contain data and perhaps almost no behaviour? In other languages creating a type will help you enforce certain restrictions and because of type checks the IDE will help you program, this is not always the case in python, so what should I do? Should I resort to creating a class only when there's both, behaviour and data? Or create a movie class even though it'll probably be just a data container? This all depends on your model, in this particular case either one is fine but I'm wondering about what's a good practice.

• Best directory to store application data with read\write rights for all users?

  - by Wodzu

  Hi guys. Until Windows Vista I was saving my application data into the directory where the program was located. The most common place was "C:\Program Files\MyApplication". As we know, under Vista and later the common user does't have rights to write under "Program Files" folder. So my first idea was to save the application data under "All Useres\Application Data" folder. But it seams that this folder has writing restrictions too! So to sum up, my requirements are: Folder should exist under Windows XP and above Microsoft's systems. All useres of the system should read\write\creation rights to this folder and it subfolders and files. I want to have only one copy of file\files for all useres. Thanks for your time.

• store data in asp.net pages (Not Sessions)

  - by ARB

  I am creating 4 asp.net pages. first three pages have 'CONTINUE' button and last page has 'SUBMIT' button. I am not allowed to use Sessions to store first three pages data. and i need to use 'BACK' button on last three pages. when i click 'BACK' button i need to maintain the previous page data entered by user. As my pages do some postbacks, i cannot use javascript.history function. My restrictions are: As the application is served from a web farm, a session object cannot be used. However, for the purpose of this excersise, consider session object as database-like persistent space where you can store your data. your code should show an easy way to switch to a different persistent space. What is databse like persistent space and how to write a code to switch to different persistent space?... Please give me some idea on how to proceed.... Thank you

• Info on Seam's EntityQuery?

  - by Shadowman

  I've been working with Seam and JPA/Hibernate for quite some time, but have just started looking at making use of the EntityHome and EntityQuery classes more. EntityHome seems relatively straightforward in terms of what it is and how I can leverage it. But, EntityQuery is a bit less clear. I understand the ability to grab, for example, a list containing all of a given entity. However, I've also seen some examples using a RESTRICTIONS array. How exactly is this used? Are the OR conditions or AND conditions? Can anyone give me some more detailed information as to how EntityQuery is intended to be used? I've checked the few books I have on Seam and JPA, but none of them really reference the EntityQuery classes. It seems like I very useful mechanism, and I'd like to get some more use out of them if I can. Thanks!

• Regex to find a word, then extract a line containing the first occurence of a different word immedia

  - by Hinchy

  World's most convuluted title I know, an example should explain it better. I have a large txt file in the below format, though details and amount of lines will change everytime: Username: john_joe Owner: John Joe Account: CLI: Default: LGICMD: Flags: Primary days: Secondary days: No access restrictions Expiration: Pwdlifetime: Last Login: Maxjobs: Maxacctjobs: Maxdetach: Prclm: Prio: Queprio: CPU: Authorized Privileges: BYPASS Default Privileges: SYSPRV This sequence is repeated a couple of thousand times for different users. I need to find every user (ideally the entire first line of the above) that has SYSPRV under "Default Permissions". I know I could write an application to do this, I was just hoping their might be a nice regex I could use. Cheers

• Change a registry value in vb.net

  - by mhofer

  Hello, I have searched a lot to find a solution for my problem, but I can't find any specific solution. I need to change a value which is stored under HKEY_LOCAL_MACHINE\SOFTWARE\APP_NAME. It is not possible to use .NET's registry functions, since they have drastic restrictions. The following snippet should solve my problem: Dim regKey As RegistryKey Dim ver As Decimal regKey = My.Computer.Registry.LocalMachine.OpenSubKey("HKEY_LOCAL_MACHINE\SOFTWARE\APP_NAME", True) regKey.SetValue("IP", "192.168.10.15:18500") regKey.Close() Unfortunately, I get a NullReferenceExeption when I try to set the value. What should I do? I have imported Microsoft.Win32 and RegistryKey doesn't accept any constructor... cheers mike

• Associate specific file extensions with my delphi app - any library for this?

  - by michal

  Hi, so far if I had to associate the file extension with my application I used to simply modify the registry. However I haven't been doing it for years, and I'm afraid the things might have changed a bit. I have no idea how to prevent registry access restrictions in Windows 7 / Vista (if there are any for HKEY_CLASSES_ROOT). Thus I'm looking for some delphi library, unit, code snippet or whatever which works reliably under XP, Vista and 7. Is there any which handles "backup" as well? By backup I mean possibility to revert the changes to the previous association ... Thanks in advance, m.

• Viewing directory containing MIME encoded email messages

  - by Mark

  I have an application which generates and sends MIME encoded messages (javax.mail.internet.MimeMessage) through an SMTP server. As part of the development process only, I'd like to be able to view these messages rather than send them (I know the sending works just fine, but there are restrictions on the domains within the dev environment which makes it a little difficult) I thought the easiest way would be to save the text for each message to a directory, then point "an app" at the directory and check them over. So the question is, what would be a good app to use? Is it as simple as configuring Outlook or another email client to do it? Thanks

• How to read loaded image into a blob?

  - by Gajus Kuizinas

  I am facing same-origin policy restrictions when loading remote images. However DOM 0 Image object can be used to load a remote resource (this is essentially the same as creating an <img /> tag). var fr = new FileReader(), img = new Image(); img.src = 'http://distilleryimage8.s3.amazonaws.com/6cf25568491a11e2af8422000a9e28e9_7.jpg'; img.onload = function () { // how to get this image as a Blob object? }; Is there a way to read this resource into a Blob/arraybuffer object? This is not a duplicate of How to convert an image object to a binary blob as the latter does not rise with same-origin issues.

• Is directly executing SQL bad app design?

  - by Michael Lowman

  I'm developing an iOS application that's a manager/viewer for another project. The idea is the app will be able to process the data stored in a database into a number of visualizations-- the overall effect being similar to cacti. I'm making the visualizations fully user-configurable: the user defines what she wants to see and adds restrictions. She might specify, for instance, to graph a metric over the last three weeks with user accounts that are currently active and aren't based in the United States. My problem is that the only design I can think of is more or less passing direct SQL from the iOS app to the backend server to be executed against the database. I know it's bad practice and everything should be written in terms of stored procedures. But how else do I maintain enough flexiblity to keep fully user-defined queries? While the application does compose the SQL, direct SQL is never visible or injectable by the user. That's all abstracted away in UIDateTimeChoosers, UIPickerViews, and the like.

• Authorization/Licensing of Webservice

  - by Burhan

  I have developed a web service which accepts the login credentials from the XML message passed to it. I have concerns over this method as the developer who consumes the service can easily share the login credentials and my service can be called from some other application that uses the same credentials. Is there any way that I can issue a 'license' to some specific applications? So that, even if credentials are shared among the consuming apps, only authorized ones can successfully consume the service. P.S: I thought about implementing IP restrictions but that doesn't serve the purpose as we may have different applications installed on a same server (we do have such a scenario implemented).

• Java: Is it possible to have a generic class that only takes types that can be compared?

  - by mr popo

  I wanted to do something along the lines of: public class MyClass<T implements Comparable> { .... } But I can't, since, apparently, generics only accept restrictions with subclasses, and not interfaces. It's important that I'm able to compare the types inside the class, so how should I go about doing this? Ideally I'd be able to keep the type safety of Generics and not have to convert the T's to Object as well, or just not write a lot of code overall. In other words, the simplest the better.

  I can't figure out how to fetch n random rows from a criteria instance: Criteria criteria = session.createCriteria(Table.class); criteria.add(Restrictions.eq('fieldVariable', anyValue)); ... Then what? I can't find any doc with Criteria API Does it mean I should use HQL instead? Thanx! EDIT: I get the number of rows by: int max = criteria.setProjecxtion(Projections.rowCount()).uniqueResult(); How do I fetch n random rows with indexes between 0 and max? Thx again!

• Flex: How to create a floating notification message of sorts for a custom component?

  - by aberrant80

  I have a custom TextInput-based component for date and time with certain restrictions on what's considered "within range". But it's still fine to insert dates that are outside the range. When a user types in a date, on valueCommit, I'd like to be able to display a hovering notification to the user, to inform/warn them that the date is outside the accepted range. I'm thinking of notifications ala the Validators, but I'd rather not use the Validator mechanism because it's really not validation, just notification. Something like a tooltip, but it will only appear if the user changed the value. Maybe an effect of some sort? If anyone has any ideas or if anyone has done something like this, I'm all ears!

• How do I "think in AngularJS" if I have a jQuery background?

  - by Mark Rajcok

  How do I “think in AngularJS” if I have a jQuery background? Suppose I'm familiar with developing client-side applications in jQuery, but now I'd like to start using AngularJS. Can you describe the paradigm shift that is necessary? Here are a few questions that might help you frame an answer: How do I architect and design client-side web applications differently? What is the biggest difference? What should I stop doing/using; what should I start doing/using instead? Are there any server-side considerations/restrictions? I'm not looking for a detailed comparison between jQuery and AngularJS.

• Best way of obfuscating / encrypting form data on the iPhone

  - by cannyboy

  I want to create an app which holds sensitive information (imagine it's bank account details, thought it's not). The user enters this information on a form the first time the app starts up. I want this info to be saved, and available, any time the user uses the app (without having to enter a password). However, if the iPhone has a password lock on it, and is stolen, I don't want the data to be easily accessible from the file system. What is the best way of encrypting or obfuscating the data? There is not a lot of data, just a dozen NSStrings from the UITextFields on the form. I'm aware there are encryption export restrictions on the iPhone for non-US developers (I am in UK), so I would prefer to avoid going jumping through any of Apple's app submission hoops to get it on the store.
