  - by joeb

  I'm trying to create an inheritable class(OF t) in vb.net that I will pass it a class of objects.

  Iam trying to pass the value stored in the variable fieldCSV to file data.csv...Ive used javascript and php to do this..

• Accessing and encoding of properties files

  - by NoozNooz42

  I'm used to work with properties files, for example from Ant. Where I can simply reference the property file doing something like that: <property file="webapp_DO_NOT_COMMIT.properties"/> (the file is so named because our DVCS is configured as to never commit files containing "DO_NOT_COMMIT" to prevent committing credentials/passwords/etc.) Here's a very simple .properties file example: passwd=brokencleartextpassword Now I want to put some configuration in another, similar, properties file that I need to access from my Java code. How should I go about it? I also have another related question: is the character encoding of .properties file defined by any spec?

• PHP MySQL Insert Data

  - by happyCoding25

  Hello, Im trying to insert data into a table in MySQL. I found/modified some code from w3Schools and still couldn't get it working. Heres what I have so far: <?php $rusername=$_POST['username']; $rname=$_POST['name']; $remail=$_POST['emailadr']; $rpassword=$_POST['pass']; $rconfirmpassword=$_POST['cpass']; if ($rpassword==$rconfirmpassword) { $con = mysql_connect("host","user","password"); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("mydbname ", $con); } mysql_query("INSERT INTO members (id, username, password) VALUES ('4', $rusername, $rpassword)"); ?> Did I mistype something? To my understanding "members" is the name of the table. If anyone knows whats wrong I appreciate the help. Thanks

• Best way to use Cradle with Express.js (CouchDB, Node.js)

  - by Costa

  I'm building my website ( http://tedxgramercy.jit.su ) with express.js and so far I've been using the http.request method in node to access couch, and that's been cool. I've learned lots about how http, couch, and node work, which is awesome. Anyways, I'm thinking of moving over to cradle now (Let me know if you have a strong opinion about this) and I'd like to know the "right" way to set this up. Should I... require() cradle and make a new connection to my db in each separate route? create my database connection once, and then just pass that connection by require()ing the connection in each route? (if so, how do I do that?) Thanks!!!

• How to handle #(hash) character in SEO friendly url?

  - by arvinsim

  How do you bypass the default behaviour if #(hash) which is to go to a specific part of a page? The problem that I have is that the # character is a part of the SEO friendly url which is a title and the #(hash) is part of the content (i.e. like with C#). I can't retrieve the whole string and I only get the characters before the #. Example: www.domain.com/C#-programming-book in this example I only get 'C' and not the '-programming-book' part. I am not using any javascript at the moment and would like to only use a PHP solution for this. Before anyone suggests that I used url encoding, the criteria for the seo friendly url is that it should be human readable and easily remembered. So converting the hash to '%23' does not pass the criteria. Is there no way around it?

• How to use the merge command

  - by Vaccano

  Say I have a table called Employee (has ID, NAME, ADDRESS, and PHONE columns). (Not my real problem, but simplified to make the question easier.) If I call a sproc called UpdateEmployee and I pass in a @Name, @Address, @Phone and @ID. Can merge be used to easily check to see if the ID exists? If it does to update the name, address and phone? and if it does not to insert them? I see examples on the net, but they are huge and hairy. I would like a nice simple example if possible. (We recently upgraded to SQL 2008, so I am new to the merge command.)

• MVC3 application I want javascript methods to fire on passed in route values

  - by DavieDave

  I have an MVC3 application in Visual Studio 2010. I have a view with several dropdowns that do javascript calls to populate dropdowns based on the selected value, some of which are disabled initially. That all works great with the initial state of nothing. If I however pass routevalues to the dropdowns from a redirect to this action, I do get the value set correctly but it's not enabled like it should be on the dropdown for example and when I post the form, the ones that are greyed out are not passed back on the form. How can I correct this?

• php string to array and split

  - by RussP

  Hi folks Looking for suggestions as to the best way to do this (I know there are many options): take a variable like this: $args = ('post_type=post&order_by=DESC&limit=10'); the create a function to convert that variable into parts like this: $post_type = post; $order_by = DESC; $limit= 10; Reason is I want a client to be able to use a string like the first to pass variables to a sql query in much the same way (but doesn't have to be exact) as you can do it in WordPress.

• Passing Session[] and Request[] to Methods in C#

  - by NYARROW

  In C#, How do you pass the Session[] and Request[] objects to a method? I would like to use a method to parse out Session and Request paramaters for a .aspx page to reduce the size of my Page_Load method. I am passing quite a few variables, and need to support both POSTand GET methods. For most calls, not all variables are present, so I have to test every variable multiple ways, and the code gets long... This is what I am trying to do, but I can't seem to properly identify the Session and Request paramaters (this code will not compile, because the arrays are indexed by number) static string getParam( System.Web.SessionState.HttpSessionState[] Session, System.Web.HttpRequest[] Request, string id) { string rslt = ""; try { rslt = Session[id].ToString(); } catch { try { rslt = Request[id].ToString(); } catch { } } return rslt; } From Page_Load, I want to call this method as follows to retrieve the "MODE" paramater: string rslt; rslt = getParam(Session, Request, "MODE"); Thanks!

• How to check if people liked my Facebook FanPage

  - by user2372419

  There are many questions and answers about this. But nowadays Facebook changes their Privacy. Any Application that request for user_likes permission must be review by Facebook before using. I've tried many times to explain to Facebook review team about my app, but they did not accept, because my application (a web game using HTML5 and JavaScript) require people like my fan page before play. So my question is: Is there any to bypass Facebook privacy? I have a Like Box on the same page as the game screen (where i need to check Like), so any solution (like: analyze DOM elements, capture screen can pass through image recognition) will fine.

• Boost Shared Pointers and Memory Management

  - by Izza

  I began using boost rather recently and am impressed by the functionality and APIs provided. In using boost::shared_ptr, when I check the program with Valgrind, I found a considerable number of "Still reachable" memory leaks. As per the documentation of Valgrind, these are not a problem. However, since I used to use the standard C++ library only, I always made sure that any program written is completely free from memory leaks. My question is, are these memory leaks something to worry about? I tried using reset(), however it only decrements the reference count, doesn't deallocate memory. Can I safely ignore these, or any way to forcibly deallocate the memory allocated by boost::shared_ptr? Thank you.

• PHP callback function not being called

  - by Industrial

  Hi everyone, I've got the following code: function _callback_memcache_failure($host, $port) { print "memcache '$host:$port' failed"; } $this->memcache = new Memcache; $this->memcache->addServer('192.168.1.35', '11211', 0, 50, 10, TRUE, _callback_memcache_failure('192.168.1.35','11211')); The server is online and running (verified!), but the Failure callback function is being called at each connection. Why is that? Reference: PHP documentation: Memcache::addServer - failure_callback Allows the user to specify a callback function to run upon encountering an error. The callback is run before failover is attempted. The function takes two parameters, the hostname and port of the failed server .

• object consisting of jQuery element

  - by Adam Kiss

  hello, current code I've built function to do something over collection of jQuery elements: var collection = $([]); //empty collection I add them with: collection = collection.add(e); and remove with: collection = collection.not(e); It's pretty straightforward solution, works nicely. problem Now, I would like to have an object consisting of various settings set to any jQuery element, i.e.: function addObject(e){ var o = { alpha: .6 //float base: {r: 255, g: 255, b: 255} //color object } e.data('settings', o); } But when I pass jQuery object/element to function (i.e. as e), calling e.data doesn't work, although it would be simplest and really nice solution. question If I have an "collection" of jQuery elements, what is the simplest way of storing some data for each element of set?

• How can I store and access SQLite databases from a central location?

  - by Brian Ramsay

  I have installed SQLite on my UNIX system, and am planning on accessing it from PHP. However, the database is created in the directory I initialize it in, and if a script runs in a different directory a new database is created in the same directory. Is there an option for SQLite (or the PHP wrappers) to create the databases in one location, and have those databases accessible just by name outside of that directory? Ideally, I'd like to be able to do something like $db=new SQLiteDatabase("db.test"); in any directory and have it reference the same database, if that makes sense.

• Updating GUI Component from a different class C# WPF

  - by Boardy

  Hi all, I am trying to update a GUI component (DataGrid) in one class from a different class. I am using C# and WPF Forms. When I used the standard WF forms I could pass a reference to the GUI component as a parameter to the function that needed to do the work with the DataGrid. However, I do not know how I can do this in WPF. I have Class1 which has the GUI component and I need Class3 to run the function inside Class2 which will automatically update the GUI display of the Datagrid found in Class1. Any help with this would be much appreciated.

• .NET web service call slower when performed asynchronously

  - by joelt

  I have an ASP.NET site, and some pages need to call a web service. I used Visual Studio's "Add Web Reference" to auto-generate classes and methods for the web service. When I call the service synchronously, i.e. objService.MethodName("param1"), a call might take a second or so. When I call it asynchronously, i.e., objService.BeginMethodName("param1", AddressOf MyCallback, Nothing), it typically takes about 6 seconds. When debugging, it appears that the bulk of the time is spent waiting between the completion of the BeginMethodName call and the beginning of MyCallback. Does the thread switching really incur that much overhead? Is there another reason for this?

• Windows XP batch file concat

  - by dls

  I'm trying to accomplish the following ridiculous task: I have a text file containing a set of fully qualified filesnames. I want to iterate through the file and append each line to a common variable, that can be passed to a command line tool. For example, the file might be: C:\dir\test.txt C:\WINDOWS\test2.txt C:\text3.txt and I'd like to assign them to some variable 'a' such that: a = "C:\dir\test.txt C:\WINDOWS\test2.txt C:\text2.txt" A secondary question is - what is a good batch file reference? I'm finding some stuff in the Windows material, and a lot of home-grown websites, but nothing particularly complete. Thanks!

• c++ classes & lua

  - by anon

  I want to have C++ objects that I can read/write in both C++ & Lua. I have looked at: http://www.lua.org/pil/28.html However, I do not like that solution, since my objects have constructors & destructors (and they are important as I use RAII and these take care of reference counts). What I don't like in the PIL solution is that the object is allocated in Lua's heap. What i want instead, is to create hte C++ object on my own, and just have lua have a way to do get/set on them. Does anyone have a good tutorial/link on this? Tanks!

• 2 ajax forms on the same page posting same textbox

  - by rod

  Hi All, Is it possible to post, say like a value in a textbox, to 2 different ajax forms that are on the same page? It doesn't have to be at the same time? What I'm trying to do is this: I have a search page that searches for customers and displays them on a paged grid. Users can specify up to 5 parameters (5 textboxes) to narrow the search. On the same page I have an export option. Well since I want all the customers for the search and not just the paged data I need a way to post back to the server for this option passing the same parameters used in the grid. I'm using a ViewModel which would be nice if I can pass that back to the server rather than the individual search fields that are backed by the view model. Thanks, rodchar

• Is there a way to get the current UIEvent being handled?

  - by not-

  I'm working in a class that is a delegate of another class; this other class is in a third-party library that I'd like to avoid changing if at all possible. The original class is handling a -touchesEnded event, and is delegating responsibility to me, but it doesn't pass the UIEvent itself to me. Is there a way to get a handle to the current event in progress? It's a double-tap handler, and all that is passed to me is the view being touched, and the point at which the touch occurred. I want to know exactly how many touches are involved in the event. Thanks! randy

• Ajax image upload and javascript edit on the fly with ASP.NET MVC (without saving to disk)

  - by gavss

  1) Uploadimage action gets requests from form posts. <form action="/content/uploadimage" method="post" enctype="multipart/form-data"> It reads HttpPostedFileBase stream data and sends it to the response. I need to show the image in a div container instead of sending it to the response as a file so that users can manipulate the image using jcrop. Image source is generated at runtime. I can't pass an action name to the src attribute. Is this possible using MVC and without using control viewstate? 2) I don't want to use flash or silverlight. Is there an easy ajax alternative to the method I use to get files from user?

• correct technical term for this pattern

  - by Oliver A.

  sometimes I use a pattern which is very similar to the singleton pattern: There is one default instance which and a static get method to aces it. But you may create other instances and pass it as optional parameter and if you want to and you can even replace the default instance with a instance from a child class. So it is NO SINGLETON at all but it is used like one singleton in most cases. Anyone got an idea who to call something like this ? Maybe half*** singleton? domiton?

• How to convert unicode character to its escaped ascii equivalent in c#

  - by Grant

  Hi, i am beginning with a string containing an encoded unicode character "& #xfc;". I pass the string to an object that performs some logic and returns another string. That string is converting the original encoded character to its unicode equivalent "ü". I need to get the original encoded character back but so far am not able. I have tried using the HttpUtility.HtmlEncode() method but that is returning "& #252;" which is not the same. Can anyone help?
