• TFS: How do I view .cs files in the VS IDE when viewing details of a shelveset?

  - by Josh Leonard

  For our code review process we open the details of a shelveset to see all files that have been worked on. Right clicking and choosing "Compare" works great for existing ( modified ) files. But, when a file has been added I just want to view the file. Double clicking ( or right click - view ) opens .cs ( and .sql )files in notepad. When I try to open a .PRC file ( extension for our stored procedures ) I get a prompt that allows me to choose what program to use for viewing. Does anyone know how to get this prompt to show up for .cs files ( and all other files, for that matter ) Thanks!

• code deployment options

  - by bobinabottle

  We've been looking at automating our server and code deployments. We've already decided on puppet for our server configurations, but are looking for a more "push" style tool to use for code deployments. I'm currently looking at either using capistrano or fabric, but I'm not sure what would be the most mature to use? We deploy a number of different services, none of which are currenlty written in rails or django, so we don't mind about language. What would be the best one to build custom deployment scripts? Or have I missed another tool out there? We are also considering git pushing with hooks for deployment, but feel it will be limited/hacky in what we want to achieve with it. Any thoughts or experience would be great to hear. Cheers

• Qt: any way to automatically generate QSharedData-based structures?

  - by Eye of Hell

  Hello. Qt has a build-in supprt for creating objects with integrated reference counting via QSharedData and QSharedDataPointer. All wordks great, but for each such object i need to write a lot of code: QSharedData-based implementation class with constructor and copy constructor, object class itsef with accessor methods for each filed. For a simple structures with 5-10 fields this requires really lot of near same code. Is it some ways to automate such classes generation? Maybe it's some generators exists that take a short description and automatically generates implementation class and object class with all accessors?

• Improve performance writing 10 million records to text file using windows service

  - by user1039583

  I'm fetching more than 10 millions of records from database and writing to a text file. It takes hours of time to complete this operation. Is there any option to use TPL features here? It would be great if someone could get me started implementing this with the TPL. using (FileStream fStream = new FileStream("d:\\file.txt", FileMode.OpenOrCreate, FileAccess.ReadWrite)) { BufferedStream bStream = new BufferedStream(fStream); TextWriter writer = new StreamWriter(bStream); for (int i = 0; i < 100000000; i++) { writer.WriteLine(i); } bStream.Flush(); writer.Flush(); // empty buffer; fStream.Flush(); }

• Single page app with high number of images working extremely slow on iOS8 safari/Webview

  - by NikhilWanpal

  We are working on a WebView (not WKWebView, yet) app, are are observing that the app runs extremely slow on iOS 8. The same app runs smooth on lower versions of OS like iOS7 and iOS6. So we tried it in safari on iOS8 and the performance is similar to iOS6 and 7. The app is filled with images and many are high resolution. While trying to trace the issue (trial and error!) we reduced the sizes and resolutions of the images and the performance improved, but it is still not at par with versions 6 and 7. We are unable to find any such issues reported elsewhere and are stuck. It would be great if we could get some pointers on this one.

• How to respond to any kind of interruption?

  - by mystify

  My app is playing a pretty complex animation. It's like a flipbook. What I do is: I have a huge loop with selectors, and after every delayed call the next one is called. Now someone calls the user and the device suddenly shows up this fat green status bar and maybe some big pick-up-the-phone-call overlay. Or: The alarm clock rings, and a big alert sheet appears in front of just about everything. It would be great to just pause the whole animation in case of ANY interruption. Probably I've also missed like 5 more possible interruptions. How are you doing that? How do you get notified for all interruptions and then call one single -stopEverything method?

• jquery - setting a limit of items, that can be dragged into a list

  - by maschek

  Hi, i have this two lists, from which i can move items from one to another with jquery ui and connect lists, with ajax. If an item is pulled over, a message is generated in a php file and then it appears on screen. Now i want that for example the right list should be allowed to contain ten items at max. It would be great if it would be possible with jquery, that if there is already ten items in the list and you go and drag the eleventh, if then the item would somehow vanish, maybe with a little effekt. I think maybe reading out db in the php-file if theres already ten items, and so on. But i have currently no idea, if and in case if in which way, jquery would support this kind of behaviour. Can you give me some advise? Greetings, maschek

• Scala Eclipse IDE suddenly ignoring breakpoints

  - by malsmith

  I've been using Scala 2.8RC1 and Scala Eclipse plugin for 2.8 RC1 happily for a few days. However, last night after adding a couple jar files to my environment (apache http client jars) the debugger just stopped stopping at breakpoints in scala code. Java code stops fine at breakpoints. I tried creating a new mimimal scala app breakpoints don't stop. I've tried switching to sun-jre-1.6.0.20 from the openjdk-1.6.18 I had been using. I've switched to the scala 2.8 nightly and also eclipse plugin for scala nightly builds. No luck. I would greatly appreciate ideas for fixes. Rather frustrating as the initial experience with 2.8 was really great.

• FastCGI, PHP, Sendmail, and Codeigniter

  - by Kyle J. Dye

  Hi Everyone. I am experiencing an odd issue. I just switched to FastCGI (Apache) because of the big performance boost. Everything is working great, except when I attempt to use sendmail (Codeigniter Class or just raw PHP). I have tested with and without CI and still get a 500 internal server error when trying to send. Could this be getting caused by a discrepency in how FastCGI utilizes sendmail? Has anyone else experienced this issue? Also, the email will send, it just errors afterwards. Please let me know a solution if you have one! Thanks! :)

• $("body").scrollTop() doesn't update in safari

  - by Kristoffer Nolgren

  I'm working on a website: http://beta.projektopia.se/ the body has several background-images that are updated on scroll like this: $(document).ready(function(){ $(document).scroll(function(){ var scrollfactor=$("body").scrollTop()*0.2; var centerscrollpos =scrollfactor+613; var docheight = $(document).height(); var windowheight = $(window).height(); var bottompos = (docheight-980)-((docheight-windowheight)*0.2)+scrollfactor; var scrollpos = 'center '+scrollfactor+'px,center '+bottompos+'px, center '+ centerscrollpos+'px,center 0px'; $("body").css("background-position", scrollpos); }); }); Lots of calculations, but the important thing is that a scrollpos is created that should change the position of the background when you scroll, to create a parallax-effect. It works great in chrome, but in firefox, the variable scrollfactor, that is suppose to get the current scroll-position, doesn't update. ps, some people have this issue due to lack of correct doctype. I believe i have declared it correctly like this: <!DOCTYPE html>

• WYSIWYG editor that is intergrated with Ruby on Rails

  - by atmorell

  Hello, I have worked with Ruby on Rails for the last four years. So far I have used textmate for writing the code. This is working great as long as I don't need to do any decent presentation. I was wondering if there is any WYSIWYG editor out there that can intergrate with Rails. Something like Dreamweaver with the ability to browse Objects etc. If I have opened the _show.erb I create a div and selete @user.email. etc. Any suggestions?

• gcalFeed is not a function?

  - by fossildesigns

  I set up a calendar for the department at the university where I work (http://www.uwsp.edu/conted/calendar/default.aspx), this works just great. I then turned around and uploaded all the jquery files and fullcalendar.css to my development server (http://fossilfoundry.com/test/test.htm). When the page loads I get a JavaScript Error stating that $.fullCalendar.gcalFeed is not a function. All the files are local to the .htm page. I've checked everything I can think of. Any ideas why this won't run?

• Haskell: reading multiple command line arguments

  - by Survot

  Hi all, Okay, so I am making a program in Haskell that needs to change certain words based on two command line arguments. I have made the replace function and everything works great, but I am stumped getting it to work with command line arguments. Here is the main code: (replace function not included) main = do text <- getContents (command1:command2:_) <- getArgs putStrLn (replace (read command1) (read command2) text) So for intstance in the terminal I want to be able to type something like: "--- cat textfile.txt | ./replace oldword newword" I know this code is close since I have seen others do it this way. O_o Thanks for any help

• How to create a user customizable database (like Zoho creator) in Rails?

  - by martjno

  I'm learning Rails, and the target of my experiments is to realize something similar to Zoho Creator, Flexlist or Mytaskhelper, i.e. an app where the user can create his own database schema and views. What's the best strategy to pursue this? I saw something about the Entity-Attribute-Value but I'm not sure whether it's the best strategy or if there is some support in Rails for it. If there was any tutorial in Rails about a similar project it would be great. Probably it's not the easiest star for learning a new language and framework, but it would be something I really plan to do since a long time.

• sharepoint spweb and spsite disposal

  - by user327045

  I've been using the following code in a .NET 1.1 SharePoint 2003 environment and it works great: try { site = SPControl.GetContextSite(Context); web = site.OpenWeb(); ... } catch (Exception export) { output.Write("Caught Exception: <br/><br/>"); output.Write(export.Message + "<br><br>"); output.Write(export.StackTrace); } finally { if (web != null) web.Dispose(); if (site != null) site.Dispose(); } However, I'm currently porting the code to a .NET 2.0 SharePoint 2007 environment and I get the following error message: "Trying to use an SPWeb object that has been closed or disposed and is no longer valid." If I comment out the Dispose() code, it works fine. But won't this cause memory leaks? What's the best way to fix the problem?

• MySQL searching using many 'like' operators: is there a better way?

  - by DrAgonmoray

  I have a page that gets all rows from a table in a database, then displays the rows in an HTML table. That works great, but now I want to implement a 'search' feature. There is a searchbox, and search-terms are separated by a space. I am going to make it search three fields for the search terms, 'make' 'model' and 'type.' These three fields are VARCHAR(30). Currently if I wanted to search using 3 terms (say 'cool' 'abc' and '123') my query would look something like this. SELECT * FROM table WHERE make LIKE '%cool%' OR make LIKE '%abc%' OR make LIKE '%123%' OR model LIKE '%cool%' OR model LIKE '%abc%' OR model LIKE '%123%' OR type LIKE '%cool%' OR type LIKE '%abc%' OR type LIKE '%123%' That looks really bad, and it will get even worse if there are more search terms or more fields to search. My question to you: is there a better way to search? If so, what?

• understanding memory mapping in directx

  - by numerical25

  So my question is ... " When your using the mapping feature to write into a memory buffer, are you really just saving the whole procedure into a queue so directX executes it when finished with other tasks???" I ask this question because this is my perception of mapping when writing to a buffer. I just want to make sure my perception is correct. I understand that the monitor moves extremely slow in compared to the processor, and I am sure the processor can execute 10 times the amount the screen can refresh. So is this one of the reason you should map when writing to a buffer. so each procedure can be done in a orderly fashion. If someone could elaborate, that would be great. thanks

• What is the max LINQ Expression Trees can do?

  - by yeeen

  What is the maximun that LINQ expression Tree can do? Can it define a class? How about a method, with all the declared name, modifiers, parametertype and return type? Must the program always define the tree himself? Is it possible to generate the tree from a given C# file? Where can I get resources to learn about writing basic to advanced Expression Tree and Expression Tree Visitor? (articles and videos will be great) Thanks for those who are able to help...

• Can I use meteor for this?

  - by nitelord

  I'm looking for a way to create an app which has a realtime web interface as well as an API which can be called by a node.js client while sharing most of its code. I'd like to be able to manage data, monitor and execute tasks inside of my app via browser, but also have an automation/scheduling program which connects to my web app and tells it to run various tasks and get results of each task. Unfortunately it doesn't look like I can connect to Meteor from the server, so I'm wondering if there's another approach? Is what I described even possible using Meteor? I have done some testing using socket.io and I think I may be able to do it this way, but Meteor seems like it'd be really great for the realtime user interface.

• After changing position labels of items are gone

  - by unresolved_external

  I have FrameLayout, which has buttondeclared like this: <Button android:id="@+id/button_face_popup_more" android:layout_alignParentRight="true" android:layout_width="wrap_content" android:layout_height="wrap_content" android:padding="10dp" android:text="@string/more" android:textColor="#1c1c1c" android:textSize="15dp" android:singleLine="true" android:ellipsize="end" /> When I add it to the ViewGroup in the first time, everything is great. But when I need to replace it according to screen size: if ( screenHeight < h + popupRect.top ) { removeView(mPopupView); //((Button) mPopupView.findViewById(R.id.button_face_popup_more)).setText(R.string.more); addView(mPopupView, popupRect.left, screenHeight - h, popupRect.width()); } I got button with no label. What can be the issue? Almost forgot when I check in debug mText filed of that button in both cases, when it is displayeed and when it is not, it equals "".

• Best method of Zend Framework caching

  - by iamthejeff

  I have a blog built using Zend Framework, which I realize might be a bit overkill for a blog alone, but I am planning on adding other features in the future. Nevertheless, I've noticed pages could be a little speedier. I've done a basic caching method that basically captures everything in index.php (Core frontend and File backend), which works great, but unfortunately it also prevents dynamic page contents from updating (messages like "this was posted 5 minutes ago", etc) until the cache period expires. So my question is what would be the best method of caching to improve performance? I am doing fairly basic queries which are mostly simple selects, not many joins or anything fancy (using Zend_Db_Table), and even on a small database page loads are a little sluggish. Is it worth it to cache queries or should I focus my time elsewhere?

• How? Encrypt and Decrypt user membership passwords in ASP.NET

  - by smdrager

  We are creating a new site using ASP.NET membership provider for user registration and log in. Our old system encrypted user passwords so that we could recover them if we needed to. I am having a great deal of trouble figuring out if it is possible to use ASP.NET membership functions to simply encrypt the password when the user registers and then unencrypt it so I can see it. Documentation for this is neigh non-existant. I know how to configure Web.config to have it store passwords as encrypted ala passwordFormat="Hashed" in the provider and assigning a validationKey in the machineKey, however it seems like the password still gets hashed (though perhaps it is just well encrypted). Either way I cannot decifer how the password can be recovered (by us) if neccessary. Thanks!

• Sliding & Fading controls on a C# form

  - by Tommy

  Hey there, I'm trying to implement a way to slide&fade controls around (more than one at the same time possibly) elegantly. So in other words, say i had a picture in the top left corner, and a texbox in the bottom right corner, i'd like to be able to have them slide. not just snap. slide, to the opposite corners and replace eachothers position. Ive been working for awhile but have not come up with anything efficient, even just some of the basic math calculations would be a great start.

• Merging contents of two lists based on a if-loop

  - by chavanak

  I have a minor problem while checking for elements in a list: I have two files with contents something like this file 1: file2: 47 358 47 48 450 49 49 56 50 I parsed both files into two lists and used the following code to check for i in file_1: for j in file_2: j = j.split() if i == j[1]: x=' '.join(j) I am now trying to get a "0" if the value of file_1 is not there in file_2 for example, value "48" is not there is file_2 so I need to get the output like (with only one space in between the two numbers): output_file: 358 47 0 48 450 49 56 50 I tried using the dictionary approach but I didn't quite get what I wanted (actually I don't know how to use dictionary in python correctly ;)). Any help will be great.

• How to tell a UITableView to preload all Rows?

  - by Infinite

  Is there a way to tell a UITableView to preload all rows? The tableView is supposed to show several comments (up to 80 comments). So my CommentCell uses a Setter to adapt the cell to a specific comment. -(void)setComment:(Comment *)newComment { if (newComment != comment) { [comment release]; comment = [newComment retain]; /* * set the cells view variables here */ } } This specific setter takes quite a bunch of processing resources and scrolling gets kinda laggy. I am using a comment-specific reuseIdentifier instead of a static cellIdentifier when calling dequeueReusableCellWithIdentifier: in order to assure, that "newComment" equals the old "comment". And in fact this does work great when scrolling over cells which have already been loaded. But when scrolling through the comments for the first time, it still lags like hell. Which leads me to my question: Is there a way to tell the tableview to preload all cells? (which I doubt) or Do I have to implement my own cache instead of relying on "dequeueReusableCellWithIdentifier:"?
