• Tips about a good class-structure for website? (php)

  - by Martti Laine

  Hello I'm creating a kind of massive network for users to register and login. I want to try using classes, but I've never used them (expect some mysql-wrappers etc). Could you provide some tips and sample-structure for my project? The idea is to simply have a index.php, which prints the whole page and does all the action. Index.php calls functions from classes inside other files. I need: user-class for checking if logged in and retrieving user-info different kind of "page"-classes for functions needed in those pages I'm not asking for full code, but just a start. I don't know, how to use public functions or anything like that. How to wrap these classes to work together? So no functions, just the structure! Martti Laine

• Very long tree control inside a <frame>

  - by ryancerium

  I have an tree control inside of a frame. It's quite tall, around 2000 pixels. Right now, we use the frame's scroll bars, which is mostly good. Unfortunately, when you select an item near the bottom of the list, the page reloads and the view goes back to the top of the list. I tried calling the tree control's ScrollNodeIntoView() function, but since we're not using the tree's scroll bars, it just thinks that it's displaying the full 2000 pixels and the control doesn't have its own scroll bar. I'm not much of an HTML guru, so I have two ideas, neither of which I know how to do. 1) Tell the frame to not to let the tree render all 2000 pixels and instead stay inside the viewable area. 2) Tell the tree to not render all 2000 pixels and instead stay within the viewable area. Setting the CSS height property on the within the frame doesn't do anything. Thanks.

• Sql Distinct Count of resulting table with no conditionals

  - by AfterImage

  Hello everyone, I want to count the number of accounts from the resulting table generated from this code. This way, I know how many people liked blue at one time. Select Distinct PEOPLE.FullName, PEOPLE.FavColor From PEOPLE Where FavColor='Blue' Lets say this is a history accounting of what people said their favorite color when they were asked so there may be multiple records of the same full name if asked again at a much later time; hence the distinct. The code I used may not be reusable in your answer so feel free to use what you think can work. I am sure I found a possible solution to my problem using declare and if statements but I lost that page... so I am left with no solution. However, I think there is a way to do it without using conditionals which is what I am asking and rather have. Thanks. Edit: My question is: From the code above, is there a way to count the number of accounts in the resulting table?

• Accessing entire netflix catalog via API v1.5

  - by Stone

  Netflix recently updated their API methods for obtaining the full Netflix catalog. I'm curious if anyone has had any success accessing these new xml documents and downloading them via API v1.5 (9/2012). Previously, you could download the entire Netflix catalog via one API call (which I had working perfectly). Now, there are supposedly two calls to make: one for dvd's and one for streaming movies. I cannot make these calls return anything except for an empty array. Please don't offer an answer unless you have personally downloaded the entire catalog via these new API's. Bonus points if you can tell me how to do it in Ruby. http://developer.netflix.com/blog/read/Update_Changes_for_the_Public_API

Any clue??

• What's the best way to call jQuery scripts, in HTML/PHP template, or seperate js file?

  - by j-man86

  StackOverflow is telling me this is a subjective question, but I think it's a matter of fact! I have a number of scripts that I'm using on different parts of my site. In terms of making fewer http requests, I know it's better to combine all of these scripts into one .js file. However, isn't a waste of time for a page to call a .js full of 10 or 15 different functions when it's only using one? The other method I am using is to use PHP conditional statements... <?php if( is_page() ) { > $(document).ready(function(){ ... }); <?php } ?> What's the best method or comination of these methods?

• Licensing Scripts

  - by Mr.K

  Hi, I've had my first nightmare client recently who was messing me around with payment for a project. So... I've come to an agreement with another client to use some of the sites scripting to build a site for them. But, now the original client wants their site too. I have made a deal to licence the reused parts of the site (some jQuery scripts and a dynamic flash gallery) rather than me signing over full copyright. However, I haven't got a clue how to do this. Can anyone point me in the right direction to read up on this? Thanks

• Ripping a CD to mp3 in C# - third party component or api out there?

  - by Jonathan Williamson

  We're working on a project that requires the ripping of audio tracks from CDs to MP3s (ideally also retrieving the track information from CDDB or similar). More background information: Various music labels send us CDs of music which we then deliver to people via an online delivery system. We're looking at automating the process of converting those CDs into MP3s with full track information where possible. We want to produce a simple desktop application that allows a member of editorial staff to setup the information about the new music we receive. To streamline the process we'd like to include the ripping of the audio and retrieval of the track information.

• How can I do this Aggrigate, group by, in query in LINQ?

  - by Ólafur Waage

  Please do not give me a full working example, I want to know how this is done rather than to get some code I can copy paste This is the query I need, and can't for the life of me create it in LINQ. SELECT * FROM dbo.Schedules s, dbo.Videos v WHERE s.VideoID = v.ID AND s.ID IN ( SELECT MAX(ID) FROM dbo.Schedules WHERE ChannelID = 1 GROUP BY VideoID ) ORDER BY v.Rating DESC, s.StartTime DESC I have the "IN" query in LINQ I think, it's something like this var uniqueList = from schedule in db.Schedules where schedule.ChannelID == channelID group schedule by schedule.VideoID into s select new { id = s.Max(i => i.ID) }; It is possibly wrong, but now I can not check in another query for this in a where clause uniqueList.Contains(schedule.ID) There is possibly a better way to write this query, if you have any idea I would love some hints. I get this error and it's not making much sense. The type arguments for method 'System.Linq.Queryable.Contains(System.Linq.IQueryable, TSource)' cannot be inferred from the usage. Try specifying the type arguments explicitly.

• How can I determine whether xml serializer can serialize a file

  - by ldsenow

  Hi, How can I determine whether xml serializer can serialize a file which is in a shared location and monitored by a file monitor. The file monitor has a list of parsers which are used to parse files in the shared folder. Once a file gets dropped into the folder, the file monitor will ask the registered parsers whether any of them can handle this file, if yes, the monitor will move the file out from the shared folder and assigns the task to the parser. Since some of the files are quite big, so I need to have a quick check on each parsers. How can I determine my xml parser can serialize the file without loading the full file into the memory?

• Errors in Decimal Calcs within def clean method?

  - by allanhenderson

  I'm attempting a few simple calculations in a def clean method following validation (basically spitting out a euro conversion of retrieved uk product price on the fly). I keep getting a TypeError. Full error reads: Cannot convert {'product': , 'invoice': , 'order_discount': Decimal("0.00"), 'order_price': {...}, 'order_adjust': None, 'order_value': None, 'DELETE': False, 'id': 92, 'quantity': 8} to Decimal so I guess django is passing through the entire cleaned_data form to Decimal method. Not sure where I'm going wrong - the code I'm working with is: def clean_order_price(self): cleaned_data = self.cleaned_data data = self.data order_price = cleaned_data.get("order_price") if not order_price: try: existing_price = ProductCostPrice.objects.get(supplier=data['supplier'], product_id=cleaned_data['product'], is_latest=True) except ProductCostPrice.DoesNotExist: existing_price = None if not existing_price: raise forms.ValidationError('No match found, please enter new price') else: if data['invoice_type'] == 1: return existing_price.cost_price_gross elif data['invoice_type'] == 2: exchange = EuroExchangeRate.objects.latest('exchange_date') calc = exchange.exchange_rate * float(existing_price.cost_price_gross) calc = Decimal(str(calc)) return calc return cleaned_data If the invoice is of type 2 (a euro invoice) then the system should grab the latest exchange rate and apply that to the matching UK pound price pulled through to get euro result. Should performing a decimal conversion be a problem within def clean method? Thanks

• Cloud Apps and Single Sign-On (AD integration)

  - by Pablo Alvim

  I've been investigating some cloud vendors and the ability to implement single sign-on with them, especially when it comes to AD (Active Directory) integration. So far I've learned that with Azure this is possible through ADFS and the AppFabric Access Control offer. In AWS, since it is possible to create a VPN and see EC2 instances as a natural extension of a private datacenter, I believe implementing SSO would be rather simple (not sure if I'm right on this one... Please correct me if I'm wrong). With App Engine though, even though there is some documentation on AD synchronization (not full integration) for Google Apps, I'm struggling to find out whether AD integration would be possible... Is there any strategy for that? Any bit of information on cloud apps and AD integration will be appreciated!

• Instance where embedded C++ compilers don't support multiple inheritance?

  - by Nathan

  I read a bit about a previous attempt to make a C++ standard for embedded platforms where they specifically said multiple inheritance was bad and thus not supported. From what I understand, this was never implemented as a mainstream thing and most embedded C++ compilers support most standard C++ constructs. Are there cases where a compiler on a current embedded platform (i.e. something not more than a few years old) absolutely does not support multiple inheritance? I don't really want to do multiple inheritance in a sense where I have a child with two full implementations of a class. What I am most interested in is inheriting from a single implementation of a class and then also inheriting one or more pure virtual classes as interfaces only. This is roughly equivalent to Java/.Net where I can extend only one class but implement as many interfaces as I need. In C++ this is all done through multiple inheritance rather than being able to specifically define an interface and declare a class implements it.

• Safe to cast pointer to a forward-declared class to its true base class in C++?

  - by Matt DiMeo

  In one header file I have: #include "BaseClass.h" // a forward declaration of DerivedClass, which extends class BaseClass. class DerivedClass ; class Foo { DerivedClass *derived ; void someMethod() { // this is the cast I'm worried about. ((BaseClass*)derived)->baseClassMethod() ; } }; Now, DerivedClass is (in its own header file) derived from BaseClass, but the compiler doesn't know that at the time it's reading the definition above for class Foo. However, Foo refers to DerivedClass pointers and DerivedClass refers to Foo pointers, so they can't both know each other's declaration. First question is whether it's safe (according to C++ spec, not in any given compiler) to cast a derived class pointer to its base class pointer type in the absence of a full definition of the derived class. Second question is whether there's a better approach. I'm aware I could move someMethod()'s body out of the class definition, but in this case it's important that it be inlined (part of an actual, measured hotspot - I'm not guessing).

• help with converting javascript function to php

  - by Haroldo

  My javascript isnt so great, but i found a brilliant looking function here I'm not sure what to do with this bit: var ranges = [], rstart, rend; full function: function getRanges(array) { var ranges = [], rstart, rend; for (var i = 0; i < array.length; i++) { rstart = array[i]; rend = rstart; while (array[i + 1] - array[i] == 1) { rend = array[i + 1]; // increment the index if the numbers sequential i++; } ranges.push(rstart == rend ? rstart+'' : rstart + '-' + rend); } return ranges; } getRanges([2,3,4,5,10,18,19,20]); // returns ["2-5", "10", "18-20"] getRanges([1,2,3,5,7,9,10,11,12,14 ]); // returns ["1-3", "5", "7", "9-12", "14"] getRanges([1,2,3,4,5,6,7,8,9,10]) // returns ["1-10"]

• How to generate Makefiles with Cmake to create tarballs of project?

  - by Rizo

  I like to keep my Makefiles flexible and multifunctional. One of the tasks I usually add to make command is tar, for example the following instruction does the job: tar: tar -cvf $(PROGNAME).tar $(SRCS) Makefile My question is: How can CMake be used to generate personalized commands like tar? I would like to see some code samples. For the full functionality it would be useful to create project's components and be able to use them as parameters. (Exempli gratia: archive only header files or some specific library). Thanks in advance for your answers!

• Asp.net Report Viewer - Custom filter parameters

  - by Chris

  Hi all, for a data warehouse project I need to know about some best practices regarding custom report viewer filters/parameters. Usually I use the standard parameter feature for reports, like multiple select boxes, check boxes, text boxes etc.. But for the current project some reports require more complex report parameters. E.g. a user wants to analyze some measures. For that the user needs to set a filter on a specific address. There are over 100.000 address to choose from, so he has to have the ability to search for an address (full text). Since such features cannot be done with the standard parameters, I will have to create custom params within a ASPX page which are then passed to the report viewer control. So my question is: Are there any best practices on how to create custom parameters? Did anyone had similar problems, if so, how did you solve it?

• how to insert page view of a node in another page in drupal

  - by sprugman

  I have a list of node ids and I want to display the 'page' view of each one. For various reasons, I don't want to do this with views, and don't think I should need a module. Just an API call to theme('node'). Something like: $nids = array(3,4,5); foreach ($nids as $nid) { $node = node_load($nid); $result .= theme('node', $node); } but I'm not getting back the full page view of the node. I added this to my node-[type].tpl.php file: if ($page) print "PAGE MODE "; else print "NOT PAGE "; if ($teaser) print "TEASER MODE "; else print "NOT TEASER "; and got: NOT PAGE NOT TEASER I seem to be in some kind of limbo. I suspect there's an argument that I add to the theme function, but the terms are all so general (theme, teaser, page, node), I'm having trouble with my google-fu.

• LINQ saving images to varbinary

  - by m4rc

  I'm having issues saving images to a varbinary(Max) field using LINQ. I can save files in the region of 10KB to the database no problems, but when it comes to files bigger than that, it's as though it doesn't even try. I've had a look in the SQL Server Profiler and when the file is around 10KB I can see the full insert statement in the detail pane. However, when the file is a bit bigger, the detail pane doesn't show anything, although any data besides the varbinary field is written to the database. The data is in the Data Object just before SubmitChanges so I can't figure out what's happening between now and then!

• jQuery Plugin: Adding Callback functionality

  - by dclowd9901

  I'm trying to give my plugin callback functionality, and I'd like for it to operate in a somewhat traditional way: myPlugin({options}, function() { /* code to execute */ }); or myPlugin({options}, anotherFunction()); How do I handle that parameter in the code? Is it treated as one full entity? I'm pretty sure I know where I'd place the executory code, but how do I get the code to execute? I can't seem to find a lot of literature on the topic, so thanks in advance for your help.

• arboroaks.net/lakelandhills verse lakelandhillsatarboroaks.com , which is best for SEO?

  - by Roeland

  I am trying to decide what is the best way to approach a site I built with SEO in mind. The site has a parent site (sort of a splash page) (arboroaks.net) and the 3 children sites. Parent site is one page, and each of the 3 child sites is about 8-10pages. Right now I have the 3 child sites set up as folders under arboroaks.net. For example, lakelandhills, a child site, would be arboroaks.net/lakelandhills. I have the full domain, arboroaksatlakelandhills.com redirect to this url (arboroaks.net/lakelandhills). My question is whether I should have the child sites be contained on their own domain or not. Think lakelandhillsatarboroaks.com/about-us.php verse arboroaks.net/lakelandhills/about-us.php. The main reason is obviously for SEO consideration. Thanks!

To me it seems that when a file is opened: 1. it would need to be parsed and decided what type of source file it is. Trusting the extension might not be full-proof a way to know what keywords/commands apply to what language a way to decide what color each keyword/command gets I want to do this on OS X, C++ or Objective-C Can anyone provide pointers on how I might get started with this?
