  • Dynamically creating/inserting into an associative array in PHP

    - by emil.mp
    I'm trying to build an associative array in PHP dynamically, and not quite getting my strategy right. Basically, I want to insert a value at a certain depth in the array structure, for instance: $array['first']['second']['third'] = $val; Now, the thing is, I'm not sure if that depth is available, and if it isn't, I want to create the keys (and arrays) for each level, and finally insert the value at the correct level. Since I'm doing this quite a lot in my code, I grew tired of doing a whole bunch of "array_key_exists", so I wanted to do a function that builds the array for me, given a list of the level keys. Any help on a good strategy for this is appreciated. I'm sure there is a pretty simple way, I'm just not getting it...

  • How should I do this (business logic) in Sql Server? A constraint?

    - by Pure.Krome
    Hi folks, I wish to add some type of business logic constraint to a table, but not sure how / where. I have a table with the following fields. ID INTEGER IDENTITY HubId INTEGER CategoryId INTEGER IsFeatured BIT Foo NVARCHAR(200) etc. So what i wish is that you can only have one featured thingy, per articleId + hubId. eg. 1, 1, 1, 1, 'blah' -- Ok. 2, 1, 2, 1, 'more blah' -- Also Ok 3, 1, 1, 1, 'aaa' -- constraint error 4, 1, 1, 0, 'asdasdad' -- Ok. 5, 1, 1, 0, 'bbbb' -- Ok. etc. so the third row to be inserterd would fail because that hub AND category already have a featured thingy. Is this possible?

  • Java Authenticator on a per connection basis?

    - by Martijn Laarman
    I'm building an Eclipse plugin that talks to a REST interface which uses Basic Authentication. When the authentication fails I would like to popup my plugin's settings dialog and retry. Normally I could use the static Authenticator.setDefault() to setup an authenticator for all HttpURLConnection's for this, but since I am writing a plugin I don't want to overwrite Eclipse's default Authenticator (org.eclipse.ui.internal.net.auth); I thought of setting my custom Authenticator before loading and putting Eclipse's default back afterwards, but I imagine this will cause all sorts of race issues with multithreading so I quickly lost that notion. Google searches yield all sorts of results basically telling me it's not possible: The Java URLConnection API should have a setAuthenticator(Authenticator) method for making it easier to use this class in multi-threaded context where authentication is required. Source If applications contains few third party plugins and each plugin use its own Authenticator what we should do? Each invocation of "Authenticator.setDefault()" method rewrite previously defined Authenticator... Source Are there any different approaches that might help me overcome this issue?

  • What Should be the Structure of a C++ Project?

    - by Ell
    I have recently started learning C++ and coming from a Ruby environment I have found it very hard to structure a project in a way that it still compiles correctly, I have been using Code::Blocks which is brilliant but a downside is that when I add a new header file or c++ source file, it will generate some code and even though it is only a mere 3 or 4 lines, I do not know what these lines do. First of all I would like to ask this question: What do these lines do? #ifndef TEXTGAME_H_INCLUDED #define TEXTGAME_H_INCLUDED #endif // TEXTGAME_H_INCLUDED My second question is, do I need to #include both the .h file and the .cpp file, and in which order. My third question is where can I find the GNU GCC Compiler that, I beleive, was packaged with Code::Blocks and how do I use it without Code::Blocks? I would rather develop in a notepad++ sort of way because that is what I'm used to in Ruby but since C++ is compiled, you may think differently (please give advice and views on that as well) Thanks in advance, ell.

  • Bandwidth Monitoring in asp.net

    - by asifch
    HI, We are developing a multi-tenant application in Asp.Net with separate DB for each tenant, in which one of the requirement is to monitor the bandwidth usage for each tenant, i have tried to search but not found much help on the topic,we want to monitor exactly how much bandwidth is being used for each tenant while each tenant can have its own top level domain or a sub domain or a combination of both. so what are the available options, the ones which i can think of can be 1. IIS Log Monitoring means a separate application which will calculate the bandwidth for each tenant. 2. Log Each Request and Response for a tenant from within the application and then calculate the total bandwidth usage based on that. 3. Use some third part components if available So what do you think will be the best approach, also if there is any other way to do this.

  • Persistent SQL Table lock from C#

    - by Chris
    I'm trying to create a persistent SQL (SQL Server 2005) lock on a table level. I'm not updating/querying the specified table, but I need to prevent a third party application from updating the locked table as a means to prevent transactions from being posted (the table I wish to lock is the key on their transaction that interferes with my processing). From my experience the table is only locked for the time a specific transaction is taking place. Any ideas? The 3rd party developer has logged this feature as an enhancement, but since they are in the middle of rolling out a major release I can expect to wait at least 6 months for this. I know that this isn't a great solution, since their software will fall over but it is of a critical enough nature that we're willing to live with the consequences.

  • Union - Same table, excluding previous results MySQL

    - by user82302124
    I'm trying to write a query that will: Run a query, give me (x) number of rows (limit 4) If that query didn't give me the 4 I need, run a second query limit 4-(x) and exclude the ids from the first query A third query that acts like the second I have this: (SELECT *, 1 as SORY_QUERY1 FROM xbamZ where state = 'Minnesota' and industry = 'Miscellaneous' and id != '229' limit 4) UNION (SELECT *, 2 FROM xbamZ where state = 'Minnesota' limit 2) UNION (SELECT *, 3 FROM xbamZ where industry = 'Miscellaneous' limit 1) How (or is?) do I do that? Am I close? This query gives me duplicates

  • Expected symbol problems with this function declaration

    - by Derek
    I am just getting back into the C programming realm and I am having an issue that I think is linker related. I am using cmake for the first time as well, so that could be adding to my frustration. I have included a third party header file that contains a typedef that my code is trying to use, and it has this line: typedef struct a a_t so my code has a_t *var; //later..... var->member;// this line throws the error which throws the error: dereferencing pointer to incomplete type So am I just missing another include file, or is this a linker issue? I am building this code in QtCreator and using cmake. I can dive on a_t to see that typedef declaration in the included header, but I can't seem to dive on "struct a" itself to see where it's coming from. Thanks

  • Forming a SOAP request message through WSDL

    - by Shahzad
    I'm very new to webservices. I'm trying to figure out how I can formulate a request message (and determine what the response message) would be based on the wsdl description that I have. This is from a third party web service. The WSDL description that I have access to gives me a bunch of information like <types> <message> <operation> etc. But in the examples that I've seen online, it's showing the request mesage within the "soap:envelope" tag. What am I missing? Eventually I'd like to be able to call this webservice using JQuery. But I can't even figure out how to formulate the request message let alone make an ajax call to it. any help would be appreciated.

  • DataGridView that always has one row selected

    - by Dan Neely
    I'm using a DGV to show a list of images with text captions as a picklist. Their must always be a one and only one selection made in the list. I can't find a way to prevent the user from clearing the selection with a control-click on the selected row. Is there a property in the designer I'm missing that could do this? If I have to override the behavior in the mouse click events are there other ways the user could clear the current selection that need covered as well? Is there a third approach I could take that's less cumbersome than my second idea?

  • Best approach to update a control after an Ajax request?

    - by Cuga
    I have a webpage that fires off an Ajax request which stores some data to a database and I want to update the webpage so that the user can see their changes have been submitted. There are at least 3 ways I can think of accomplishing this: Immediately update the webpage with plain JavaScript by grabbing the contents of the user's inputted text and immediately inserting it where it belongs. Have the ajax call return the stored text as the response, grab the response, and then insert this text where it belongs on the page using JavaScript Have the ajax call return a flag (say, true for successful db write, false otherwise), and if the flag is true, use JavaScript to grab the user's contents from the input control and insert it where it belongs elsewhere on the page Or another method not mentioned...? I don't mean this to be subjective, I just don't know which would be the best method to apply. My instinct tells me to go with the third item (return a flag, then update the field). Is this the best way? Thanks

  • Building a user subscription application

    - by Tristan O'Neil
    Hello, I'm trying to come up with the best way to handle user subscription and management for our magazine website. What I want to happen is a user purchases a subscription and they are granted online access of a certain membership role for a certain amount of time depending on how many years they subscribed for. I would also like the system to be able to send out emails when a subscription is almost up. I've seen some third party projects to help accomplish this but I'd prefer to write this from scratch as I want total control over how it works. Any suggestions would be helpful. The main thing I can't figure out is how to have an expiring membership. You must keep track of when the user signed up and how long until they should expire.

  • C++ obtaining milliseconds time on Linux -- clock() doesn't seem to work properly

    - by hasen j
    On Windows, clock() returns the time in milliseconds, but on this Linux box I'm working on, it rounds it to the nearest 1000 so the precision is only to the "second" level and not to the milliseconds level. I found a solution with Qt using the QTime class, instantiating an object and calling start() on it then calling elapsed() to get the number of milliseconds elapsed. I got kind of lucky because I'm working with Qt to begin with, but I'd like a solution that doesn't rely on third party libraries, Is there no standard way to do this? UPDATE Please don't recommend Boost .. If Boost and Qt can do it, surely it's not magic, there must be something standard that they're using!

  • Quick way to get an NSDictionary from an XML NSData representation?

    - by dontWatchMyProfile
    I've loaded an XML file as NSData into memory and parse over the elements using NSXMLParser. Although it works, it's a very ugly and hard to maintain code since there are about 150 different elements to parse. I know there are nice third-party solutions, but I want to keep it with the iPhone SDK for purpose of practice and fun. So I thought: Why not convert that XML file into an NSDictionary? Having this, I could use fast enumeration to go over the elements. Or is it just the same amount of ugly code needed to parse and process an XML right away with NSXMLParser? Would I build up an NSDictionary for every found node in the XML and create a huge one, containing the whole structure and data? Or is there an even simpler way?

  • Restricting deletion with NHibernate

    - by FrontSvin
    I'm using NHibernate (fluent) to access an old third-party database with a bunch of tables, that are not related in any explicit way. That is a child tables does have parentID columns which contains the primary key of the parent table, but there are no foreign key relations ensuring these relations. Ideally I would like to add some foreign keys, but cannot touch the database schema. My application works fine, but I would really like impose a referential integrity rule that would prohibit deletion of parent objects if they have children, e.i. something similar 'ON DELETE RESTRICT' but maintained by NHibernate. Any ideas on how to approach this would be appreciated. Should I look into the OnDelete() method on the IInterceptor interface, or are there other ways to solve this? Of course any solution will come with a performance penalty, but I can live with that.

  • Rebuild whole page on callback?

    - by AJ
    Hello, In asp.net is it a requirement to rebuild the whole page during every callback? For example my web page is split into three distinct areas and I have an update panel for each area. Lets say I want to update the third area, do I have to bother with any processing of the other two areas? For example lets say there is a grid view in area two. The update panel in area three callbacks to update its content. Do I have to rebind the grid in area two? Thanks, AJ

    You can see the fiddle here: http://jsfiddle.net/easeS/4/ Here is the html/css I have: #main div { float:left; width:30px; margin-right:10px; } #main { overflow:hidden; width:100px; height:50px; border:1px solid; } <div id="main"> <div>test1</div> <div>test2</div> <div>test3</div> </div> I'm not sure why but it bumps the third div down to a new line instead of hiding it. Any suggestions?

  • jquery: .attr() fails for child element

    - by user984003
    I'm going crazy staring at this. I need to change the attribute of an element, something which I have done many times before. But it fails. Now I can't even get jquery to show me the attribute that it has. Does it have to do with what is returned by find()? var c = new_photo_div.find('[class = photo]')[0]; alert(c); alert(new_photo_div.attr('class')); alert(c.attr('class')); The first alert correctly identifies the element: Object HTMLImageElement The second alert correctly gives me the class of new_photo_div. The third alert fails. No alert. I think it should say: photo

  • Logical Programming Problem

    - by user353060
    Hello, I've been trying to solve this problem for quite sometime but I am having trouble with it. Let's say on a trigger, you receive values. First trigger: You get 1 Second trigger: You get 1, 2 Third trigger: You get 1, 2, 3 So, I store 1. For 2nd trigger, I store 2 since 1 already exist. For 3rd trigger, I store 3 since 1,2 already exist so in total I have stored 1,2,3 As you can see, we can easily check for new values, if old != new. Here's come the problem: Fourth trigger: You get 1, 2, 4 For 4th trigger, I store 1, 2 because it exists but how do I check against 3 and remove 3 from store and check if 4 is new? If you are having problems understanding this, feel free to clarify. Thanks!

  • Python lxml - returns null list

    I cannot figure out what is wrong with the XPATH when trying to extract a value from a webpage table. The method seems correct as I can extract the page title and other attributes, but I cannot extract the third value, it always returns an empty list? from lxml import html import requests test_url = 'SC312226' page = ('https://www.opencompany.co.uk/company/'+test_url) print 'Now searching URL: '+page data = requests.get(page) tree = html.fromstring(data.text) print tree.xpath('//title/text()') # Get page title print tree.xpath('//a/@href') # Get href attribute of all links print tree.xpath('//*[@id="financial"]/table/tbody/tr/td[1]/table/tbody/tr[2]/td[1]/div[2]/text()') Unless i'm missing something, it would appear the XPATH is correct: Chrome screenshot I checked Chrome console, appears ok!

  • Which .NET data provider?

    - by worlds-apart89
    I am new to database programming, so I'd like help getting on the right track. I have read that there are Microsoft-defined and third-party data providers for data access. MSDN has information on data providers for SQL Server, OLE DB, ODBC, Oracle, as well as the EntityClient provider (Entity Framework). Which data provider is today's hottest, most-widely used model? Which one is the future? Also, I have seen Linq to SQL tutorials, but what category does L2S fall into?
