• vb.net auto detect dependency files for wix 3.7

  - by Khan

  I am in the process of learning WIX all thanks to MS for removing such a nice tool (vdproj) from the latest versions of visual studio. I have come to know that I can add my files (and dlls) to distribute in WIX using that tag. It is OK. But in vdproj it was very easy to add all files. I just need to right click in file view, and select 'add project output'. This was enough to add dozen of files that were required for my application. In visual studio 2012, and using WIX 3.7, what options do I have to automatically list all those dlls that are required by my application?

• How to create a static delegate from main-viewcontroller?

  - by geforce

  Hi, hope someone can help me on learning some new stuff about delegates in iOS-programming. I have a "MainViewController" which is the first VC when the app starts. I´ve a kind of modelselection with different UIImageViews and after choosing one of them, i´m pushing a new VC. I want to handle the modelChoice with a delegate, so all other viewControllers can listen to that and act based on the users choice. But does that mean that i have to alloc a new instance of that "MainViewController" in every VC? Whats the solution on that? How do i create (i think its called) static delegate? Would be great to learn that.. Thanks for sharing..

• Suggested C++ books?

  - by Josh Bradley

  Ok, I've had one semester of C++ and will be taking a second semester in it after I have taken a Data Structure class this fall. In the first class, we dealt mainly with C++ syntax and the textbook we used was ok, but now I'm wanting to go ahead and purchase a great C++ book that encompasses a lot of the programming concepts used today. I'm learning Objective-C on my own and was able to get through the whole object-oriented stuff pretty easily, along with other things like pointers, inheritance, delegation, etc. It doesn't have to exactly have EVERYTHING in it, but I do want to buy the book with the most information in it. Money is no problem. So my question is what book did you use or still use for C++? Is it a book that you can reference back to if you ever forget how to do something small, or would you have to go online and find the answer.

• How can I bind a LinkedList as ItemSource to ListView in WPF XAML?

  - by Jonas

  I'm learning WPF and would like to have a collection similar to a LinkedList, to where I can add and remove strings. And I want to have a ListView that listen to that collection with databinding. How can I do bind a simple list collection to a ListView in XAML? My idea (not working) is something like this: <Window ...> <Window.Resources> <LinkedList x:Key="myList"></LinkedList> <Window.Resources> <Grid> <ListView Height="100" HorizontalAlignment="Left" Margin="88,134,0,0" Name="listView1" VerticalAlignment="Top" Width="120" ItemsSource="{Binding Source={StaticResource myList}}"/> </Grid> </Window>

• Confusion in bind call in socket programming

  - by Tarun

  i was learning socket programming in unix using c/c++. I am confused with one function call bind(params..). Actually it takes the adreess structure "sockaddr_in" and we can create the structure in the following way sockaddr_in.*** = somthing.. sockaddr_in..s_addr htonl(INADDR_ANY) **Passing INADDR_ANY will alow to bind all local addresses** My question is , why do we need to use "INADDR_ANY" ? In my knowledge every machine can has only one unique IP Address. In this way there is only one address associated with the machien. Thye bind call should directly bind the socket to the single available address. Please explain what are the different scenarios and why is it so?

• Play a video with flash (with no controls, pause, etc) and stretch to full width and height of page.

  - by Tim

  Hi, I've managed this so far: [removed url] The plan is to have that video stretch across the whole page (the flash does, the video itself does not). Firstly: well aware of the issues - bad performance, horribly stretched/pixelated video. I know this. However a client wants it so we have to do it, simple as that. Does anyone have any ideas on how this can be achieved? I've been in touch with the creators of the flash video player I'm currently using and they've confirmed it isn't possible with that flash video player. Anyone know of any players where it is possible? Thanks, Tim

• How to loop in excel without VBA or macros?

  - by Jeff

  Is there a better way for me to write this formula? Did some googling on "excel loops," but no luck. I don't have VBA or macros installed (it's not an option to install them, unfortunately). =IF('testsheet'!$C$1 <= 99,'testsheet'!$A$1,"") & IF('testsheet'!$C$2 <= 99, 'testsheet'!$A$2,"") & IF('testsheet'!$C$3 <= 99, 'testsheet'!$A$3,"") & ... and so on through !$C$40, !$A$40 ... As it is, I'll have to repeat the above code 40 times in each cell and I have over 200 cells which need the code. sniff I'm pretty good with PHP/SQL, but just learning Excel.

• Using ASP.Net 4.0 for new Dev projects

  - by JBeckton

  I am currently in the early stages of developing a couple web applications, I have not written any code yet as I am still just gathering requirements and scoping things out. I want to target ASP.Net 4.0 winforms as the platform for these apps but I want to make sure there are no glaring issues with this new version before I commit. I understand that if I was porting an existing app from 2.0, 3.5 to 4.0 there may be issues but I am starting from scratch on these projects and plan to write these apps to support the new features of 4.0. Should I wait for the first service pack to come out? Just seems like more work to start with 3.5 now only to go back through and tweak things for 4.0 in just a few months or even before I finish the app. Our servers are Win 2K3 with IIS6 and MS SQL 2000, Should I expect any problems with VS 2010 and MS SQL 2000 in regards to Linq to SQL and EF?

• How to avoid becoming a programmer while still beign closely involved with computer science/Industry

  - by WeShallOvercome

  I am studying computer science (A masters at an Ivy league), however most of the jobs i find involve way too much of programming. And frankly programming is not an issue, however programming without a meaning (read financial institution (non trading), other non mainstream jobs) bore me to death! I dont want to end up becoming a .NET,C#, Java kind of programmer. Can someone tell where i should look for jobs if i wish to do some real computer science work such as Machine Learning etc. I don't mind programming but becoming a Financial Software dev at Bloomeberg or an SDET at Microsoft isn't actually one of my goals. [note: I have interviewed for intern both positions listed above, and thankfully i got an intern for a data mining position in a top 750 Alexa rank web company] Sorry if angered anyone with a subjective question

• No recent books on MPI: is it dying?

  - by Jono

  I've never used Message Passing Interface (MPI), but I've heard its name thrown about, most recently with Windows HPC Server. I had a quick look on amazon to see if there were any books on it, but they're all dated around 7 or more years ago. Is MPI still a valid technology choice for new applications, or has it been largely superceded by other distributed programming alternatives (e.g. DataSynapse GridServer)? As it's not really an implementation, but rather a standard, what is the likelihood (assuming it's not dead) that learning it will result in better design of distributed programming systems? Is there something else I should be looking at instead?

• How to keep up the interest in job?

  - by stranger

  Hi, I have been working as Software Developer for 6+ yrs. And I have worked from start ups to big companies. I always feel some elements missing in me and those are interest, passion etc. In short, I don't feel motivated while coming to work. This makes me think how my work-life balance will look like once I reach at more responsible positions. I don't want to change my field and I feel blessed as well but I think I am not working passionately for my learning, future growth, improvement, skills etc. Any pointers will be highly appreciated. Thx

• what is a TOPIC in Struts2

  - by nacho4d

  HI, I am learning struts 2 with Tiles 2 and the word "topic" shows up very frequently... What is a topic? for example: The sx:a tag (specifically the ajax a template) and the div tag support an ajax event system, providing the ability to broadcast events to topics. You can specify the topics to listen to using a comma separated list in the listenTopics attribute. What this means is that when a topic is published, usually through the ajax a template, the URL specified in the href attribute will be re-requested. Placeholder... Refresh

• Pros and Cons of Proprietary Software

  - by Jon Purdy

  Proprietary software is about as good as open-source software. There are so many problems with proprietary technologies, however, that I'm beginning to think it's best to avoid them: The software will only be maintained as long as the company exists (and profits). The level of security of the application is as unknowable as the source code. Alterations and derivative works, however necessary and beneficial, are disallowed. I simply don't see any point in even learning to use such systems as those created by Microsoft and Apple. Of course I don't pretend that ignorance is the superior option: one has to have a certain working knowledge simply because of the ubiquity of these things. I just don't see any reason why, as an independent developer, I should ever consider it a remotely good idea to actually use them. So that's the question, or discussion topic, or what have you: In what ways do developers benefit at all from using closed-source development software?

• Counting vowels in a string using recursion

  - by Daniel Love Jr

  In my python class we are learning about recursion. I understand that it's when a function calls itself, however for this particular assignment I can't figure out how exactly to get my function to call it self to get the desired results. I need to simply count the vowels in the string given to the function. def recVowelCount(s): 'return the number of vowels in s using a recursive computation' vowelcount = 0 vowels = "aEiou".lower() if s[0] in vowels: vowelcount += 1 else: ??? I'm really not sure where to go with this, it's quite frustrating. I came up with this in the end, thanks to some insight from here. def recVowelCount(s): 'return the number of vowels in s using a recursive computation' vowels = "aeiouAEIOU" if s == "": return 0 elif s[0] in vowels: return 1 + recVowelCount(s[1:]) else: return 0 + recVowelCount(s[1:])

• DependencyProperty Orientation problem

• Get list of running processes, get active process (and it's application) Flex/AIR

  - by Adam Kiss

  Hello, just a quickie (or maybe not:] ): Is it possible to get somehow list of running applications/processes and, while running in background, check which process is active? Additionally - if somehow, the answer was yes, is it possible to react for change of active window / application react just as if it was Event, or bind to it custom event (e.g. Event.SystemActiveAppChange)? Thank you for answers as well as pointers. EDIT: Due to probable missunderstanding, I mean local applications - on your win/mac/linux machine - I would like to (in process of learning of language) track what apps I use the most, make a little graph maybe? So, the point is: in AIR app, developed in FLEX, I would like to get/list all running applications/processes, as well as which one is active (on user's PC/Mac/Linux)

• Using scanf() in C++ programs is faster than using cin ?

  - by zeroDivisible

  Hello, I don't know if this is true, but when I was reading FAQ on one of the problem providing sites, I found something, that poke my attention: Check your input/output methods. In C++, using cin and cout is too slow. Use these, and you will guarantee not being able to solve any problem with a decent amount of input or output. Use printf and scanf instead. Can someone please clarify this? Is really using scanf() in C++ programs faster than using cin something ? If yes, that is it a good practice to use it in C++ programs? I thought that it was C specific, though I am just learning C++...

• Microsoft Team System Equivalent stack.

  - by Nix

  I am looking for a free alternative to TS. What would be the best alternative stack(source control, bug tracking, project management/planning, wiki, automated builds (ci))? Keeping in mind that it would be nice if they all integrated well. For example, it would be nice to be able to link bugs to source control, and then be able to link to a project plan and then be able to automate building. I do not have issues with using Microsoft project to manage project planing. I know i would like to use these....: SVN TeamCity NUnit But i am struggling to find a good Wiki/Project Planning/Bug tracking, that would integrate well. Any questions let me know.

• Attach 1 or more (non image) files to rails application, with having to install an image-processing

  - by Hinchy

  Hi all, I'm currently learning rails by creating a simple project management app. I've gotten to the point where I would like to be allow a user upload multiple files - pdfs, docs, xls etc. The user only needs to be able to attach one file at a time, but the possibilty to have multiple documents associated with a project is a must. I've spent quite a lot of time researching my options, and it appears the two main plugins are attachment_fu and paperclip. From what I've read though, these appear to concentrate specifically on the upload and subsequent resizing of images, something I couldn't care less about. Is there a simpler way to achieve what I'm trying? Thank you all in advance.

• Tracking/Counting Word Frequency

  - by Joel Martinez

  I'd like to get some community consensus on a good design to be able to store and query word frequency counts. I'm building an application in which I have to parse text inputs and store how many times a word has appeared (over time). So given the following inputs: "To Kill a Mocking Bird" "Mocking a piano player" Would store the following values: Word Count ------------- To 1 Kill 1 A 2 Mocking 2 Bird 1 Piano 1 Player 1 And later be able to quickly query for the count value of a given arbitrary word. My current plan is to simply store the words and counts in a database, and rely on caching word count values ... But I suspect that I won't get enough cache hits to make this a viable solution long term. Can anyone suggest algorithms, or data structures, or any other idea that might make this a well-performing solution?

• Is there a better way to do SELECT queries in MySQL and sort them in PHP than this way?

  - by Kent

  I am just learning PHP/MySQL, one this I am having to do a lot is displaying data that was previously inserted into the database out to the user's browser. So I am doing this: $select = mysql_query('SELECT * FROM pages'); while ($return = mysql_fetch_assoc($select)) { $title = $return['title']; $author = $return['author']; $content = $return['content']; } then I can use these variables through out the page. Now, doing it the above way isn't an issue when I only have 3 columns in a database but what if I am dealing with a huge database with many more columns. I have a nagging feeling that the pros do it in some more efficient way where they maybe loop through the table they are selecting from to find all columns it has and associate them with variables automatically. Is that the case? or is the above how you guys do it too?

• How do I use the Microsoft VSTO interfaces?

  - by user557554

  hi, I would like to create an addin for microsoft outlook, and am using the visual studio tools to do so. However I am really struggling to get my head around the use of interfaces within the VSTO environment - the resources on MSDN show many useful looking interfaces, but I am unsure how to use these interfaces to access data. For example I am trying to add a new folder into an IMAP account but am finding it very difficult to work out how to get outlook to do so. Can anyone recommend any good resources for learning how to use VSTO (I have VSTO for dummies, but it doesn't cover the level of detail I need, I have been using MSDN, but I have found it doesnt offer much information on how to use the interfaces etc.) thanks.

• Customized generation/filtering resources with maven

  - by zamza

  I wonder what is the Maven way in my situation. My application has a bunch of configuration files, let's call them profiles. Each profile configuration file is a *.properties file, that contains keys/values and some comments on these keys/values semantics. The idea is to generate these *.properties to have unified comments in all of them. My plan is to create a template.properties file that contains something like #Comments for key1/value1 key1=${key1.value} #Comments for key2/value2 key2=${key2.value} and a bunch of files like #profile_data_1.properties key1.value=profile_1_key_1_value key2.value=profile_1_key_2_value #profile_data_2.properties key1.value=profile_2_key_1_value key2.value=profile_2_key_2_value Then bind to generate-resources phase to create a copy of template.properties per profile_data_*, and filter that copy with profile_data_*.properties as a filter. The easiest way is probably to create an ant build file and use antrun plugin. But that is not a Maven way, is it? Other option is to create a Maven plugin for that tiny task. Somehow, I don't like that idea (plugin deployment is not what I want very much).
