• Can you have a web application project produce multiple DLLS?

  - by chris

  I have a VS 2008 web application project that is getting large. My structure looks like: - WebRoot - Common/ - Foo/ - Bar/ - Baz/ so I end up with a single Webroot.dll that contains the code for common, foo, bar, and baz. Is it possible to set it so that I end up with common/ in webroot.dll, and code in foo ends up in foo.dll, bar in bar.dll, etc? Update: A couple of suggestions to move some stuff into class libraries. We already have a dozen or so separate class library projects as part of the solution; Foo, Bar and Baz contain nothing but web forms and the associated code-behinds, so moving them into separate class library projects is not feasible.

• mysql_fetch_object on complex objects

  - by Arsenal

  Say for example I have the follwoing DB structure Table book id title ... Table Author id name ... Table BookAuthor id bookid authorid And in PHP I have the following object class Book { var $id; var $title; var $authors = array(); function Book() {} } class Author { var $id; var $name; function Author(){} } Now, would it be possible using mysql_fetch_object to retrieve the bookobject including the authors as an array of author objects? If it's possible I'm pretty sure you'll need the basic inner join query SELECT * FROM tblbook INNER JOIN tblbookauthor on ... (wel you get the point) Is it possible? thanks!

• How do I parse this JSON with jQuery?

  - by Mike

  So I had this structure in xml and I was able to parse it successfully. Now what I have done is that I converted this xml into a JSON using www.xmltojson.org but I am not able to parse it . I am setting these files locally on we localhost web server: <script> $(function() { $.ajax({ url:'feed.json', dataType:'json', type:'GET', success:function(json) { /// what to do here }. error: { alert("Parse Failed"); } }); }); </script> I am trying to learn JSON, so I am little unsure as to where I am doing wrong, or even if that is the correct approah. Thanks Mikey.

• Is it good practice to initialize array in C/C++?

  - by sand

  I recently encountered a case where I need to compare two files (golden and expected) for verification of test results and even though the data written to both the files were same, the files does not match. On further investigation, I found that there is a structure which contains some integers and a char array of 64 bytes, and not all the bytes of char array were getting used in most of the cases and unused fields from the array contain random data and that was causing the mismatch. This brought me ask the question whether it is good practice to initialize the array in C/C++ as well, as it is done in Java?

• Django - User account with multiple identities

  - by Scott Willman

  Synopsis: Each User account has a UserProfile to hold extended info like phone numbers, addresses, etc. Then, a User account can have multiple Identities. There are multiple types of identities that hold different types of information. The structure would be like so: User |<-FK- UserProfile | |<-FK- IdentityType1 |<-FK- IdentityType1 |<-FK- IdentityType2 |<-FK- IdentityType3 (current) |<-FK- IdentityType3 |<-FK- IdentityType3 The User account can be connected to n number of Identities of different types but can only use one Identity at a time. Seemingly, the Django way would be to collect all of the connected identities (user.IdentityType1_set.select_related()) into a QuerySet and then check each one for some kind of 'current' field. Question: Can anyone think of a better way to select the 'current' marked Identity than doing three DB queries (one for each IdentityType)?

• Best way to store application images taken via camera

  - by Dave

  Hi all, I'm just looking for some insight into what would be the best way for me to store images as part of my app. I have an activity that represents a 'Job' which has a couple of edittext's and underneath was planning on using the Gallery component to show images relevant to this job. The job data is stored in a database (on the sdcard) so was also thinking of creating a table to store 'JobImages' and having each image stored as a byte array. But I'm not sure if it would be better to store the images directly on sdcard under a folder structure specific to my application and the job. E.g. using the job ID number as a folder name. Depending on which method I use will greatly determine the code that goes into an 'adapter' that allows me to bind to the gallery component so before I begin I was wondering if anyone has had the same design problem and what option they chose. Thanks, Dave

• CodeIgniter version 2.0 is stable enough to use?

  - by ajsie

  i want to port my application to CodeIgniter but i am wondering whether i should use their v2.0 or v1.72 (then when they release 2.0, upgrade it). i have never used a framework before so i don't exactly know what implies when upgrading a framework: what does it mean practically - i just move the folders and it will work? or do i have to change a lot of settings, file structure etc? could someone enlighten me about the upgrade process. and what would you use: v.1.72 or v2.0? if i'm using the latest version, is there a good documentation for it somewhere so you can read about how to use the new features: packages, drivers and so on. thanks

• What time function do I need to use with pthread_cond_timedwait?

  - by Vincent

  The pthread_cond_timedwait function needs an absolute time in a time timespec structure. What time function I'm suppose to use to obtain the absolute time. I saw a lot of example on the web and I found almost all time function used. (ftime, clock, gettimeofday, clock_gettime (with all possible CLOCK_...). The pthread_cond_timedwait uses an absolute time. Will this waiting time affected by changing the time of the machine? Also if I get the absolute time with one of the time function, if the time of the machine change between the get and the addition of the delta time this will affect the affect the wait time? Is there a possibility to wait for an event with a relative time instead?

• Design and Implementation with Prototyping Methodology

  - by Shahin

  I'm developing a game for my dissertation, and I'm using the spiral method approach. I'm having a bit of difficulty structuring my dissertation, specifically the design and implementation section. My solution was designed as much as possible initially, and then after each prototype implementation, the design was refined and extended and prototyped again (this was repeated a few times). My problem is how to structure this in my dissertation, my current idea is: Design Chapter Prototype 1 (Initial) Design Prototype 2 Design Prototype 3 Design Implementation Chapter Prototype 1 (Initial) Implementation Prototype 2 Implementation Prototype 3 Implementation Any suggestions?

• MVC Pages that require the user to be logged in

  - by keithjgrant

  I'm working on a little MVC framework and I'm wondering what the "best way" is to structure things so secure pages/controllers always ensure the user is logged in (and thus automatically redirects to a login page--or elsewhere--if not). Obviously, there are a lot of ways to do it, but I'm wondering what solution(s) are the most common or are considered the best practice. Some ideas I had: Explicitly call user->isLoggedIn() at the beginning of your controller action method? (Seems far too easy to forget and leave an important page unsecure on accident) Make your controller extend a secureController that always checks for login in the constructor? Do this check in the model when secure information is requested? (Seems like redundant calls would be made) Something else entirely? Note: I'm working in PHP, though the question is not language-dependent.

• Suggest Sphinx index scheme

  - by htf

  Hi. In a MySQL database I have documents of different type: some have text content, meta keys, descriptions, others have code, SKU number, size and brand name and so on. The problem is, I have to search something in all of these documents and then display a single page, where the results will be grouped by the document type, such as help page, blog post, item... It's not clear for me how to implement the Sphinx index: I want to have a single index to speed up queries, but since different docs have different structure - how can I group them? I was thinking about just concatenating them, but it just doesn't feel right.

• Best way to update UI from other classes?

  - by Jack

  I've got several nested classes, with the following structure: BackupLocation contains list of BackupClients BackupClients contains a list of BackupVersions BackupVersions contains a list of BackupFiles In my UI - Im populating a combo box with BackupLocations - and have several listboxes for the clients, versions, and files. When processing the BackupLocations - I can update my status bar easily because thats the top level class that the UI creates. But how can I update the status bar and progress bar on each file being processed? Since the BackupFiles are 3 levels deep, I cant see any way to update the UI. The actual processing of the files are within the BackupVersion class - which loads its files. I think it probably has something to do with events and delegates - but am unsure exactly how to proceed with this, any help would be appreciated.

• Should all presentational images be defined in CSS?

  - by Grant Crofton

  I've been learning (X)HTML & CSS recently, and one of the main principles is that HTML is for structure and CSS for presentation. With that in mind, it seems to me that a fair number of images on most sites are just for presentation and as such should be in the CSS (with a div or span to hold them in the HTML) - for example logos, header images, backgrounds. However, while the examples in my book put some images in CSS, they are still often in the HTML. (I'm just talking about 'presentational' images, not 'structural' ones which are a key part of the content, for example photos in a photo site). Should all such images be in CSS? Or are there technical or logical reasons to keep them in the HTML? Thanks, Grant

• getResourceAsStream() is always returning null

  - by Andreas Grech

  I have the following structure in a Java Web Application: TheProject -- [Web Pages] -- -- [WEB-INF] -- -- -- abc.txt -- -- index.jsp -- [Source Packages] -- -- [wservices] -- -- -- WS.java In WS.java, I am using the following code in a Web Method: InputStream fstream = this.getClass().getResourceAsStream("abc.txt"); But it is always returning a null. I need to read from that file, and I read that if you put the files in WEB-INF, you can access them with getResourceAsStream, yet the method is always returning a null. Any ideas of what I may be doing wrong? Btw, the strange thing is that this was working, but after I performed a Clean and Build on the Project, it suddenly stopped working :/

• C++ get method - returning by value or by reference

  - by HardCoder1986

  Hello! I've go a very simple question, but unfortunately I can't figure the answer myself. Suppose I've got some data structure that holds settings and acts like a settings map. I have a GetValue(const std::string& name) method, that returns the corresponding value. Now I'm trying to figure out - what kind of return-value approach would be better. The obvious one means making my method act like std::string GetValue(const std::string& name) and return a copy of the object and rely on RVO in performance meanings. The other one would mean making two methods std::string& GetValue(...) const std::string& GetValue(...) const which generally means duplicating code or using some evil constant casts to use one of these routines twice. #Q What would be your choice in this kind of situation and why?

• Is there a name for a pure-data Objective-C class?

  - by BrianEnigma

  This is less of a code-specific question and more of an Objective-C nomenclature question. In C you have struct for pure data. In Enterprise Java, you have "bean" classes that are purely member variables with getters and setters, but no business logic. In Adobe FLEX, you have "Value Objects". In Objective-C, is there a proper name for an object (descended from NSObject, of course) that simply has ivars and getters/setters (or @property/@synthesize, if you want to get fancy) and no real business logic? A more concrete example might be a simple class with getters and setters for filename, file size, description, and assorted other metadata. You could then take a bunch of these and easily throw them into a container (NSDictionary, NSArray) without the need for messy NSValue wrapping of a C struct. It is also a little more structure than putting, say, a bunch of loosely-typed child NSDictionaries into a parent container object.

• Insert into ... Select *, how to ignore identity?

  - by Haoest

  I have a temp table with the exact structure of a concrete table T. It was created like this: select top 0 * into #tmp from T After processing and filling in content into #tmp, I want to copy the content back to T like this: insert into T select * from #tmp This is okay as long as T doesn't have identity column, but in my case it does. Is there anyways I can ignore the auto-increment identity column from #tmp when I copy to T? My motivation is to avoid having to spell out every column name in the Insert Into list. EDIT: toggling identity_insert wouldn't work because the pkeys in #tmp may collide with those in T if rows were inserted into T outside of my script, that's if #tmp has auto-incremented the pkey to sync with T's in the first place.

• What is the term(s) used to describe programming language syntax?

  - by Mr Roys

  Is there an exact/correct term to describe this difference between the syntax/constructs of programming langauges e.g VB6 with its (if ... else ... endif) and C# with its curly braces for conditional statements. I'm using VB6 syntax and C# as examples since I'm more familiar with their syntax. For example, Visual Basic 6's syntax uses a more verbose, natural language like structure. If (id = 0) Then id = MyObject.Add(Me) Else Call MyObject.Update(Me) End If while C# has more concise syntax like: if (id == 0) { id = MyObject.Add(this); } else { MyObject.Update(this); } Conciseness? Natural languageness? Or is there a more "scientific" word for describing syntax?

• How to learn about Make, compiling

  - by drozzy

  Why is Make utility for installing stuff on Linux so complicated? I mean it is really hard to know exactly where stuff goes on the machine. /etc/local? usr local? non-local? It just seems like really chaotic directory structure. Is there some "guide" on how this works? I mean as a new programmer, coming into the world of compiling things - where does on start? Thanks.

• Can you simulate a boolean flag in XSLT?

  - by R.C.

  Hey guys, I'd like to simulate a flag in an xslt script. The idea is for template foo to set a flag (or a counter variable, or anything), so that it can be accessed from template bar. Bar isn't called from foo, but from a common parent template (otherwise I would pass a parameter to it). The structure is like this: <xsl:template match="bla"> <xsl:apply-templates select="foo"/> <!-- depending on the contents of foo... --> <xsl:apply-templates select="bar"/> <!-- ... different things should happen in bar --> </xsl:template> Any tricks are much appreciated.

• How to move many files in multiple different directories (on Linux)

  - by user1335982

  My problem is that I have too many files in single directory. I cannot "ls" the directory, cos is too large. I need to move all files in better directory structure. I'm using the last 3 digits from ID as folders in reverse way. For example ID 2018972 will gotta go in /2/7/9/img_2018972.jpg. I've created the directories, but now I need help with bash script. I know the IDs, there are in range 1,300,000 - 2,000,000. But I can't handle regular expressions. I wan't to move all files like this: /images/folder/img_2018972.jpg -> /images/2/7/9/img_2018972.jpg I will appreciate any help on this subject. Thanks!
