  • open encrypted file with php

    - by stormdrain
    Hi, I'm looking for a way to open encrypted files that are stored on a server. I'm using mcrypt to encrypt the files. I was initially going to create a class that would open the file, decrypt it, write it to a new location, then open that. But I have convinced myself there is a better way (I just don't know what it is). It seems like there should be a way to stream it (?) to the browser once it's decrypted. The initial setup would just link to the file location and the browser would take over (e.g. .pdf files would bring up a dialogue offering to open or save the file). If possible, I'd like it to do the same after decoding. Pointers? Advice? Bueller? Thanks!

  • Mobile Specific Site Development. Where to start?

    - by Andy
    I'm beginning the process of learning the ins and outs of developing sites for mobile web browsers. Are there any good resources/communities online that discuss mobile specific site development issues? My initial understanding is that to cover different phones you need to build one site that is enabled for browsers with the webkit engine (iphone, android, etc.) and another more basic site for other older browsers, is this assumption correct? Also what does developing for webkit mean exactly? How is it different than just using javascript/css/html? Is it the same except that you limit yourself to webkit specific functions and css? I looked on the webkit site, but it didn't explain it in those terms. Are there any other snafus I need to watch out for when developing for mobile browsers?

  • IIS 7 Can't read data from ASP.Net application services tables

    - by vikp
    Hi, I'm working on deploying a web application written in C# with ASP.Net Application services databases. The application runs fine on the development machine. Windows Server 2003 has been built to test the application. The database has been scripted across using MS SQL Server GUI. ASP.Net application services tables were created using an utility. The connection strings are stored in the web.config and connectionStrings.config. The application connects to the database successfully, but then it times out after 10 seconds.

  • Code igniter authentication code in controller security question

    - by Prime Studios
    I have a main controller to handle the very front-end of my authentication system, it handles login, logout, update user info, etc. functions that I anticipate calling by POST'ing from views/forms. What about something like a "delete_user" function though? My thoughts are a button in someones admin panel would say "Delete Account" and it would post to "/auth/delete", and the function would delete the user based on their session username or id. This seems a bit open ended, you could send out a link to someone and when they opened it while in that application it would delete their account.. Whats the best way to handle this?

  • How to manage end user documentation for a project under continuous integration?

    - by mcdon
    I have a project under continuous integration and would like to add end user documentation to the project. The end user documentation is a user manual, not API documentation. In our environment we use windows, c#, msbuild, cruisecontrol.net and subversion. We are currently using DocToHelp to create our help file, which is based on an msword document. I'm looking for some guidance on how to manage the end user documentation. What documentation tools should I use? Should any of the documentation tools be part of the build script? Should the output files from the documentation tool be stored in subversion? What type of help files would be best to use?

  • Can this be done using Facebook Connect?

    - by SLoret
    Here is the sequence of events I would like to see happen: Visitor shows up to my site and clicks the connect button Visitor authorizes the connection by logging into their facebook account My site records their authorization My site posts to their wall "Sally just joined http://foo.com. A website about foo." Much later, my site can post other updates to the users wall using the stored authorization from step 3. Sally doesn't have to be actively on my site at the time this post to their wall happens. Thanks in advance.

  • How would you implement database updates via email?

    - by jules
    I'm building a public website which has its own domain name with pop/smtp mail services. I'm considering giving users the option to update their data via email - something similar to the functionality found in Flickr or Blogger where you email posts to a special email address. The email data is then processed and stored in the underlying database for the website. I'm using ASP.NET and SQL Server and using a shared hosting service. Any ideas how one would implement this, or if it's even possible using shared hosting? Thanks

  • Add version control to existing SQL Server database

    - by ederbf
    I am part of a development team currently working with a database that does not have any kind of source control. We work with SQL Server 2008 R2 and have always managed the DB directly with SSMS. It now has ~340 tables and ~1600 stored procedures, plus a few triggers and views, so it is not a small DB. My goal is to have the DB under version control, so I have been reading articles, like Scott Allen's series (http://bitly.com/9cJmGR) and many old SO related questions. But I am still unable to decide on how to proceed. What I'm thinking of is to script the database schema in one file, then procedures, triggers and views in one file each. Then keep everything versioned under Mercurial. But of course, every member of the team can access SSMS and directly change the schema and procedures, with the possibility that any of us can forget to replicate those changes in the versioned files. What better options are there? And, did I forget any element worth having source control of?

  • PHP - Frameworks, ORM, Encapsulation.

    - by Ian
    Programming languages/environments aside, are there many developers who are using a framework in PHP, ORM and still abide by encapsulation for the DAL/BLL? I'm managing a team of a few developers and am finding that most of the frameworks require me to do daily code inspection because my developers are using the built in ORM. Right now, I've been using a tool to generate the classes and CRUD myself, with an area for them to write additional queries/functions. What's been happening though, is they are creating vulnerabilities by not doing proper checks on data permission, or allowing the key fields to be manipulated in the form. Any suggestions, other than get a new team and a new language (I've seen Python/Ruby frameworks have the same issues).

  • Webbrowser control and cookies

    - by Mike
    Hello! I have a webbrowser control in my program and what I want to do is to delete all the cookies stored in my computer. The problem is that for example I'm in some site, and then I decide I want to delete all the cookies, so I do it by the command "Kill()" but the problem is that the cookies remain and this site still can recognize me, and to complete the kill command I need to close my program and enter it again. The webbrowser control uses Internet Explorer, and I think when you enter IE it somehow loads all the cookies into it so if you delete your cookies, they remain there. So I'm wondering how can I delete my cookies, completely delete them without the need to close my program and enter it once again. Any help will be appreciated!

  • Creating an object relational schema from a Class diagram

    - by Caylem
    Hi Ladies and Gents. I'd like some help converting the following UML diagram: UML Diagram The diagram shows 4 classes and is related to a Loyalty card scheme for an imaginary supermarket. I'd like to create an object relational data base schema from it for use with Oracle 10g/11g. Not sure where to begin, if somebody could give me a head start that would be great. Looking for actually starting the schema, show abstraction, constraints, types(subtypes, supertypes) methods and functions. Note: I'm not looking for anyone to make any comments regarding the actual classes and whether changes should be made to the Diagram, just the schema. Thanks

  • Is it possible to convert Gregorian to Hijri date in Vb ?

    - by ahmed
    Hi, I have a table in sql where the date format is stored in Hijri. Now I am working on a vb.net application where I have to let the user update that dateField. So is it possible that if I place a datepicker(which is in Gregorian) and user selects the date and its converts into Hijri date before updating. I mean when the user selects the date and clicks the save button the date should be updated in hijri format in the sql . For now , the user is entering the date manually on a tms AdvEdit. Is there any code available to accomplish this task. Thanking you all in advance for your time and consideration.

  • [Python] How can I speed up unpickling large objects if I have plenty of RAM?

    - by conradlee
    It's taking me up to an hour to read a 1-gigabyte NetworkX graph data structure using cPickle (its 1-GB when stored on disk as a binary pickle file). Note that the file quickly loads into memory. In other words, if I run: import cPickle as pickle f = open("bigNetworkXGraph.pickle","rb") binary_data = f.read() # This part doesn't take long graph = pickle.loads(binary_data) # This takes ages How can I speed this last operation up? Note that I have tried pickling the data both in using both binary protocols (1 and 2), and it doesn't seem to make much difference which protocol I use. Also note that although I am using the "loads" (meaning "load string") function above, it is loading binary data, not ascii-data. I have 128gb of RAM on the system I'm using, so I'm hoping that somebody will tell me how to increase some read buffer buried in the pickle implementation.

  • Viewing Crystal Reports other than through custom developed webform or winform apps

    - by Andrew
    At work we currently have a custom in-house built winforms app for the business users to view reports. It has role-based security and several administrator functions. My boss is thinking about getting me to port this app to webforms. My question is, are there options other than custom built winforms and webforms apps for deploying/viewing/administrating Crystal Reports at an enterprise level (role-based security, easy report deployment, etc)? I'm thinking about third-party packages or perhaps applications provided by Microsoft/Business Objects/SAP? We are using Crystal Reports 11.5.

  • Should I use implicit conversions to enforce preconditions?

    - by Malvolio
    It occurs to me that I could use use implicit conversions to both announce and enforce preconditions. Consider this: object NonNegativeDouble { implicit def int2nnd(d : Double) : NonNegativeDouble = new NonNegativeDouble(d) implicit def nnd2int(d : NonNegativeDouble) : Double = d.v def sqrt(n : NonNegativeDouble) : NonNegativeDouble = scala.math.sqrt(n) } class NonNegativeDouble(val v : Double ) { if (v < 0) { throw new IllegalArgumentException("negative value") } } object Test { def t1 = { val d : Double = NonNegativeDouble.sqrt(3.0); printf("%f\n", d); val n : Double = NonNegativeDouble.sqrt(-3.0); } } Ignore for the moment the actual vacuity of the example: my point is, the subclass NonNegativeDouble expresses the notion that a function only takes a subset of the entire range of the class's values. First is this: A good idea, a bad idea, or an obvious idea everybody else already knows about Second, this would be most useful with basic types, like Int and String. Those classes are final, of course, so is there a good way to not only use the restricted type in functions (that's what the second implicit is for) but also delegate to all methods on the underlying value (short of hand-implementing every delegation)?

  • How do I get callgrind to dump source line information?

    - by Jeremybub
    I'm trying to profile a shared library on GNU/Linux which does real-time audio processing, so performance is important. I run another program which hooks it up to the audio input and output of my system, and profile that with callgrind. Looking at the results in KCacheGrind, I get great information about what functions are taking up most of my time. However, it won't let me look at the line by line information, and instead says I need to compile it with debugging symbols and run the profiling again. The program which I am profiling is not compiled with debug symbols, but the library is. And I know this, because interestingly, source code annotations for cachegrind work fine. When I run callgrind, it says the default is to dump source line information, but it just isn't doing that. Is there some way I could force it to, or figure out what's stopping it?

  • Rails + Dragonfly gem: Saving image in a directory structure based on ActiveRecord object attributes

    - by Allen Bargi
    I'm using dragonfly gem to manage images and attachments in my rails app and I need to store images in a specific directory structure based on my user model. let' say I have user model which has a name and each user has many albums, which have a name also, then I want the images to be stored in "#{RAILS_ROOT}/public/system/#{user.name}/#{user.album.name}/#{suffix}" I've managed to changed the root_path in dragon fly and I even overrided relative_storage_path like this: class MyDataStore < Dragonfly::DataStorage::FileDataStore private def relative_storage_path(suffix) "#{suffix}" end end but still, I don't know how I can pass the ActiveRecord object attributes like user.name and user.album.name to relative_storage_path to create my ideal path. do you have any idea how I can do such a thing?

  • How to deploy a Java Swing application with an embedded JavaDB database?

    - by Jonas
    I have implemented an Java Swing application that uses an embedded JavaDB database. The database need to be stored somewhere and the database tables need to be created at the first run. What is the preferred way to do these procedures? Should I always create the database in the local directory, and first check if the database file exist, and if it doesn't exist let the user create the tables (or at least show a message that the tables will be created). Or should I let the user choose a path? but then I have to save the path somewhere. Should I save the path with Preferences.systemRoot();, and check if that variable is set on startup? If the user choses a path and save it in the Preferences, can I get any problems with user permissions? or should it be safe wherever the user store the database? Or how do I handle this? Any other suggestions for this procedure?

    Hello, I am trying to use regular expression to search a document fo a UUID number and replace the end of it with a new number. The code I have so far is: read_file = open('test.txt', 'r+') write_file = open('test.txt', 'w') r = re.compile(r'(self.uid\s*=\s*5EFF837F-EFC2-4c32-A3D4\s*)(\S+)') for l in read_file: m1 = r.match(l) if m1: new=(str,m1.group(2)) new?????? This where I get stuck. The file test.txt has the below UUID stored in it: self.uid = '5EFF837F-EFC2-4c32-A3D4-D15C7F9E1F22' I want to replace the part D15C7F9E1F22.

I have made a wallfollower robot program which has two files 1. a C program to communicate with hardware(I think we can not directly use Erlang for this) and 2. Erlang program to call these functions. I want to know where(platforms) I can run this robot. Is it possible to run this robot over micro-controller(8051 or ARM7) based hardware? Is it possible to convert Erlang program into C code or directly into .hex file? If any one have any idea please help asap. Thanks.

  • cfgrid boolean column as Yes/No

    - by Gene R
    I have a boolean type column in an html cfgrid. The data is stored in the database as 1/0 and is returned from CF as such. I want the user to see Yes/No instead of 1/0. I tried QuerySetCell, and couldn't get it to work. The form is editable, when you double click the cell, the checkboxes show and it updates as it should. The only issue is the display. <cfform> <cfgrid name="blah" format="html" bind="mycfccall" selectmode="edit"> <cfgridcolumn name="bitCol" header="Is it" width="75" type="boolean"> </cfgrid> </cfform> Thanks in advance...

  • "import as" leads to unresolved import error, "from .. import" does not

    - by Markus R.
    I'm trying to write some plugins for the irc bot supybot with eclipse/pydev. Pydev gives me errors about unresolved imports on supybot-modules/packages (e. g. import supybot.utils as utils), but works ok on e. g. "from supybot.commands import *". So I guess I set up dydev correctly, as it finds the wanted modules. The problem must be in pydev/eclipse, as the bot works correct and in eric5 I get also no errors about that. Removing the interpreter and setting it up didn't help. Any other ideas on how to fix this? System: Arch Linux, Eclipse Juno, PyDev 2.7.1, wanted (and set up) python interpreter is 2.7, supybot is installed in site-packages for Python 2.7. Edit: Just noticed: PyDev doesn't mark the "from ... import *" as error, but if I use functions imported from there I get an error on that function.

  • How to disable log4j logging from Java code

    - by Erel Segal Halevi
    I use a legacy library that writes logs using log4j. My default log4j.properties file directs the log to the console, but in some specific functions of my main program, I would like to disable logging altogether (from all classes). I tried this: Logger.getLogger(BasicImplementation.class.getName()).setLevel(Level.OFF); where "BasicImplementation" is one of the main classes that does logging, but it didn't work - the logs are still written to the console. Here is my log4j.properties: log4j.rootLogger=warn, stdout log4j.logger.ac.biu.nlp.nlp.engineml=info, logfile log4j.logger.org.BIU.utils.logging.ExperimentLogger=warn log4j.appender.stdout = org.apache.log4j.ConsoleAppender log4j.appender.stdout.layout = org.apache.log4j.PatternLayout log4j.appender.stdout.layout.ConversionPattern = %-5p %d{HH:mm:ss} [%t]: %m%n log4j.appender.logfile = ac.biu.nlp.nlp.log.BackupOlderFileAppender log4j.appender.logfile.append=false log4j.appender.logfile.layout = org.apache.log4j.PatternLayout log4j.appender.logfile.layout.ConversionPattern = %-5p %d{HH:mm:ss} [%t]: %m%n log4j.appender.logfile.File = logfile.log
