  • symfony save submitted form to database

    - by Sejanus
    Maybe I am missing something, but in symfony examples, in form submission action there's nothing which indicates form data is saved to database. (link). How can I save everything to db? Example from the link: public function executeSubmit($request) { $this->forward404Unless($request->isMethod('post')); $params = array( 'name' => $request->getParameter('name'), 'email' => $request->getParameter('email'), 'message' => $request->getParameter('message'), ); $this->redirect('contact/thankyou?'.http_build_query($params)); }

  • Advanced command line argument parsing in Java?

    - by Bishop87
    Does anyone have any java examples for parsing a series of command line arguements in a robust way? I'm looking to be able to handle something like: java myapp [-l language] [-d int] [-f file1 file2 file3] I want to do this in a robust way so I can provide logical error messages to the user if they mistake a command line-option. Some of these options I'd like to make optional, etc, etc. Also, the -f file list should be able to handle a list of files. Is there some library out there to assist me in handling this?

  • Loading and storing encryption keys from a config source

    - by Hassan Syed
    I am writing an application which has an authenticity mechanism, using HMAC-sha1, plus a CBC-blowfish pass over the data for good measure. This requires 2 keys and one ivec. I have looked at Crypto++ but the documentation is very poor (for example the HMAC documentation). So I am going oldschool and use Openssl. Whats the best way to generate and load these keys using library functions and tools ? I don't require a secure-socket therefore a x.509 certificate probably does not make sense, unless, of-course, I am missing something. So, do I need to write my own config file, or is there any infrastructure in openssl for this ? If so, could you direct me to some documentation or examples for this.

  • How to implement filter system in SQL?

    - by sadvaw
    Right now I am planning to add a filter system to my site. Examples: (ID=apple, COLOR=red, TASTE=sweet, ORIGIN=US) (ID=mango, COLOR=yellow, TASTE=sweet, ORIGIN=MEXICO) (ID=banana, COLOR=yellow, TASTE=bitter-sweet, ORIGIN=US) so now I am interested in doing the following: SELECT ID FROM thisTable WHERE COLOR='yellow' AND TASTE='SWEET' But my problem is I am doing this for multiple categories in my site, and the columns are NOT consistent. (like if the table is for handphones, then it will be BRAND, 3G-ENABLED, PRICE, COLOR, WAVELENGTH, etc) how could I design a general schema that allows this? Right now I am planning on doing: table(ID, KEY, VALUE) This allows arbitary number of columns, but for the query, I am using SELECT ID FROM table WHERE (KEY=X1 AND VALUE=V1) AND (KEY=X2 AND VALUE=V2), .. which returns an empty set. Can someone recommend a good solution to this? Note that the number of columns WILL change regularly

  • Matrix multiplication in java (RE-POST)

    - by Chapax
    Apologies for the re-post; the earlier time I'd posted I did not have all the details. My colleague, who quit the firm was a C# programmer, was forced to write Java code that involved (large, dense) matrix multiplication. He's coded his own DataTable class in Java, in order to be able to a) create indexes to sort and join with other DataTables b) do matrix multiplication. The code in its current form is NOT maintainable/extensible. I want to clean up the code, and thought using something like R within Java will help me focus on business logic rather than sorting, joining, matrix multiplication, etc. Plus, I'm very new to the concept of DataTable; I just want to replace the DataTable with 2D arrays, and let R handle the rest. (I currently do not know how to join 2 large datasets in java very efficiently Please let me know what you think. Also, are there any simple examples that I can take a look at?

  • How can one connect to an RFCOMM device other than another phone in Android?

    - by Charles Duffy
    The Android API provides examples of using listenUsingRfcommWithServiceRecord() to set up a socket and createRfcommSocketToServiceRecord() to connect to that socket. I'm trying to connect to an embedded device with a BlueSMiRF Gold chip. My working Python code (using the PyBluez library), which I'd like to port to Android, is as follows: sock = bluetooth.BluetoothSocket(proto=bluetooth.RFCOMM) sock.connect((device_addr, 1)) return sock.makefile() ...so the service to connect to is simply defined as channel 1, without any SDP lookup. As the only documented mechanism I see in the Android API does SDP lookup of a UUID, I'm slightly at a loss.

  • IIS 7.5 powershell module usage issues

    - by pmcgrath
    Has anyone managed to use this module with success, i'm running 32bit Windows 7, where i have opened an administrator shell using run as administrator, i have imported the WebAdministration module and then attempted to use the commands with some issues, have provided two examples here Websites I created a web site with the following command new-website -name testsite -port 80 -hostheader testsite -physicalpath c:\temp Then i attempted to get the sites details using the command get-website -name testsite but it always returns all sites, seems to ignore the -name parameter. Only way i can get the site is using a filter get-website | ? { $_.name -eq 'testsite' } | get-member When i use appcmd it works as expected using the following command C:\> C:\Windows\System32\inetsrv\appcmd.exe list site testsite AppPools When i try to list the apppools using the following command dir iis:\apppools i get the following error Get-ChildItem : Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)) Yet when i use appcmd as follows i get all the apppools as expected without any error C:\Windows\System32\inetsrv\appcmd.exe list apppool Has anyone successfully managed to use the WebAdministration module ? Thanks in advance Pat

  • Is Stopwatch really broken?

    - by Jakub Šturc
    At MSDN page for Stopwatch class I discovered link to interesting article which makes following statement about Stopwatch: However there are some serious issues: This can be unreliable on a PC with multiple processors. Due to a bug in the BIOS, Start() and Stop() must be executed on the same processor to get a correct result. This is unreliable on processors that do not have a constant clock speed (most processors can reduce the clock speed to conserve energy). This is explained in detail here. I am little confused. I've seen tons of examples of using Stopwatch and nobody mention this drawbacks. How serious is this? Should I avoid using Stopwatch?

  • Create iPhone app programmatically, in its entirety

    - by miorel
    I recently became interested in iPhone app development, so I've been looking at online tutorials, and also reading a book, trying out the examples as I go along. I'm getting better, but one of the things I still find quite annoying about the usual development model is that I really have no idea what the SDK is really doing behind the scenes to make the app "work" because Apple protects me from this. For example, when I make connections on interface builder, this presumably corresponds to code being generated somewhere... Where that code is and what it does and how it works are not obvious (to me). So I'm wondering, is it possible to create an iPhone app entirely programmatically? That is, have execution start in some main method, which will then programmatically create any views, register event listeners, etc. And if yes, what are some good resources for something like this?

  • Where's all the XPCOM user documentation?

    - by Graham Paulson
    Google can't find much user documentation for XPCOM. Sure, it can find endless references to making new XPCOM components in C++, but that's utterly useless to anyone who needs to know how to use the existing components from JavaScript. This is a huge gap, occasionally touched on by trivial examples of creating an instance and calling a method. Has nobody with a more in-depth knowledge of the componentry written anything about its use? Using components with multiple interfaces? Implementing listeners for handling asynchronous behaviour? "Rapid Application Development with Mozilla" is no help (great breadth but little depth). Spotty references that exist to the defunct XULPlanet redirect to Mozilla Development Center, but that's pretty useless. Mozilla Development Center articles point back to XULPlanet, which is a joke. Is this the best an army of open source advocates can muster to promote the extension of The Beast?

  • Push data to flex client

    - by KensoDev
    Howday, I want to push data to flex clients. I am talking about anywhere between 5000-15000 concurrent users, need to get data every time a currency is changed so that means lots of changes for lots of users. I have been looking into WebOrb.net, but the performance seem very poor (100 users concurrent) for a product so pricy (we purchased a license). So, I have to look into alternatives, I know there's fluorineFx but it seems no one is really using it for products and it lacks in examples and documentation. My question is: what products can answer my needs (.net backend) and what are the performance I can expect out of these products? Thanks

  • grails metaprogramming

    - by Don
    Hi, My understanding is that there are two obvious places in a Grails app where one can do meta-programming: The init closure of Bootstrap.groovy The doWithDynamicMethods closure of a plugin The meta-programming I'm referring to here should be visible throughout the metaprogramming, typical examples include adding (or replacing) methods of 3rd party classes. String.metaClass.myCustomMethod = { /* implementation omitted */ } The disadvantage of (1), is that the metaprogramming won't be applied when the application is dynamically reloaded. The disadvantage of (2) is that I need to create and maintain an entire plugin just for the sake of a little metaprogramming. Is there a better place to do this kind of metaprogramming? Thanks, Don

  • How to handle downgrade subscription for SaaS application

    - by user635800
    I am currently launching a SaaS web application. I want to have subscription packages such as: Premium: 5 users, 20 widgets, 20 MB storage Basic: 2 users, 10 widgets, 50 MB storage I want to allow companies to upgrade and downgrade packages at any time. The problem I am having is what if the company is on the premium package and has 5 users, 20 widgets, and wants to downgrade to the "basic" package. How do I handle that? Do I flag an error and say "You cannot downgrade" or do I take them to a page to remove the "extra" users and widgets? Any advice or examples of how other companies do it would be great!!

  • SQL Split function.

    - by Wardy
    Hi guys, I'm looking for a way to do this ... SELECT FirstName, LastName, Split(AddressBlock, ' ', 1), Split(AddressBlock, ' ', 2), PostCode FROM Contacts The arguments I want to pass are ... The address The separator (current situation requires 2 spaces but this might be a comma or a space followed by a comma) or something else (it varies). The address part I want to return (i don't always need all parts of the split result). I seem to be able to find a few examples of splitting functions about the internet but they return a table containing the entire set of split parts. My SQL skills aren't that great so I need the answer to be ultra simple. I'm always working with nvarchar data and the function needs to be reusable.

  • What is the C# equivalent of java.util.regex?

    - by peter.murray.rust
    I am converting Java code to C# and need to replace the use of Java's regex. A typical use is import java.util.regex.Matcher; import java.util.regex.Pattern; //... String myString = "B12"; Pattern pattern = Pattern.compile("[A-Za-z](\\d+)"); Matcher matcher = Pattern.matcher(myString); String serial = (matcher.matches()) ? matcher.group(1) : null; which should extract a capture group from a matched target string. I'd be grateful for simple examples. EDIT: I have now added the C# equivalent of the code as an answer. EDIT: Here is a tutorial on the use of the actual expressions. EDIT: Here is a useful comparison of C# and Java (and Perl.)

  • WSDL for other protocols different than SOAP?

    - by SDReyes
    From wikipedia: The Web Services Description Language (WSDL, pronounced 'wiz-d?l') is an XML-based language that provides a model for describing Web services. But in most cases, I found that WSDL is used in conjunction with SOAP. but as far as I know, if the WSDL is a language to describe web services. there should be possible to describe another kind of web services different from SOAP. is this possible? any examples? Thanks!

  • How do I use Zend Cache on this particular problem

    - by davykiash
    I have an action that renders two different view scripts based on whether the user is logged in or not. class IndexController extends Zend_Controller_Action { .... public function indexAction() { $auth = Zend_Auth::getInstance(); if($auth->hasIdentity()) { $this->render('indexregistered'); return; } else { $this->render('indexpublic'); return; } } .... } I have seen quite some useful examples on how to use the Zend Cache and they seem to be based on the fact that the action renders one particular script. What am really looking at is the best approach to cache the the indexpublic script does get quite some hits and I would live to avoid the Zend MVC overhead if possible.

  • Pulling out two separate words from a string using reg expressions?

    - by Marvin
    I need to improve on a regular expression I'm using. Currently, here it is: ^[a-zA-Z\s/-]+ I'm using it to pull out medication names from a variety of formulation strings, for example: SULFAMETHOXAZOLE-TRIMETHOPRIM 200-40 MG/5ML PO SUSP AMOX TR/POTASSIUM CLAVULANATE 125 mg-31.25 mg ORAL TABLET, CHEWABLE AMOXICILLIN TRIHYDRATE 125 mg ORAL TABLET, CHEWABLE AMOX TR/POTASSIUM CLAVULANATE 125 mg-31.25 mg ORAL TABLET, CHEWABLE Amoxicillin 1000 MG / Clavulanate 62.5 MG Extended Release Tablet The resulting matches on these examples are: SULFAMETHOXAZOLE-TRIMETHOPRIM AMOX TR/POTASSIUM CLAVULANATE AMOXICILLIN TRIHYDRATE AMOX TR/POTASSIUM CLAVULANATE Amoxicillin The first four are what I want, but on the fifth, I really need "Amoxicillin / Clavulanate". How would I pull out patterns like "Amoxicillin / Clavulanate" (in fifth row) while missing patterns like "MG/5 ML" (in the first row)?

  • DNS Lookup in ASP / ASP.Net

    - by Dave Forgac
    I have a Windows server that is intermittently losing the ability to lookup DNS information. I'm trying to get to the root cause of the problem but in the mean time I'd like to be able to monitor whether the server can perform lookups. Basically, it should attempt to lookup some common hostnames and the display 'Success' if the lookups are successful. I see lots of examples of doing this with third party components in ASP but I would prefer to be able to do this with a single ASP / ASP.Net script that would be portable and not require anything additional be installed.

  • How the return type is determined in a method that uses Linq2Sql?

    - by Richard77
    Hello, I've usually have difficulties with return types when it comes to linq. I'll explain by the following examples. Let's say I have a Table Products with ProductID, Name, Category, and Price as columns : 1) IQueryable<Product public IQueryable<Product> GetChildrenProducts() { return (from pd in db.Products where pd.Category == "Children" select pd); } 2) Product public Product GetProduct(int id) { return (from pd in db.Products where pd.ProductID == id select pd).FirstOrDefault(); } Now, if I decide to select, for instance, only one column (Price or Name) or even 2 or 3 columns (Name and Price), but in any case, less than the 4 columns, what's going to be the return type? I mean this: public returnType GetSomeInformation() { return (from pd in db.Products select new { pd.Name, pd.Price } } What SHOULD BE the returnType for the GetSomeInformation()? Thanks for helping

  • Accessing protected REST endpoint with JQuery

    - by Andy
    I have a site where members login to their account (FormsAuth). I would like to set up a RESTful service that I can access using jQuery. I would like to protect these services using the same FormsAuth. How would a third-party site be able to access these services? They would need to pass in the Principal/Identity to the service, right? I've only seen examples of Basic Authentication (which Twitter uses and jQuery supports). I'm very new to WCT/REST, so not sure how this should be done.
