• GUI to include a `.props` file to a VS 2010 project?

  - by jwfearn

  Visual Studio 2010 has no longer uses .vsprops files and instead uses .props files. To add a .vsprops file to a Visual Studio 2008 project, one could right-click the project icon in the Solution Explorer panel, choose Properties, go to the Configuration Properties | General section, and modify the Inherited Project Property Sheets property to contain a list of .vsprops paths. One could also modify the Visual Studio 2008 project file directly. Is there a way in the Visual Studio 2010 GUI to add .props files to a project? The Inherited Project Property Sheets property seems to have been removed. If manual editing of the project file is the only way to include .props files, where can one find documentation on doing it?

• Disposing of Objects with long living dependencies

  - by Ray Booysen

  public class ABC { public ABC(IEventableInstance dependency) { dependency.ANewEvent += MyEventHandler; } private void MyEventHandler(object sender, EventArgs e) { //Do Stuff } } Let us say that an instance of ABC is a long living object and that my dependency is an even longer running object. When an instance of ABC needs to be cleaned up, I have two options. One I could have a Cleanup() method to unsubscribe from the ANewEvent event or I could implement IDisposable and in the Dispose unwire the event. Now I have no control over whether the consumer will call the dispose method or even the Cleanup method should I go that route. Should I implement a Finaliser and unsubscribe then? It feels dirty but I do not want hanging instances of ABC around. Thoughts?

• Java Searchable JTree

  - by Studer

  I'm trying to use the Searchable JTree from girishchavan on a FileSystemModel from Sun. It didn't work the first time because Sun's Node implementation is a File so I transform it into DefaultMutableTreeNode to be compatible with Searchable JTree. I also edited Searchable JTree to match the path of a file. But it still doesn't work. As far as I can see, it seems that the Searchable JTree only detects the root of the original JTree and cannot go further. Maybe the Nodes are not bind to each others even if they display correctly in a JTree. How can I make it compatible ?

• Continuous builds and Agile vs commit often

  - by Mark Underwood

  Hi All, I'm just doing some formal training in Agile at the moment and one question I have is about the value of Continuous Builds vs value of committing to the version control system often. My understanding with version control is that its better to commit often, because then you have history and the ability to go back to previous changes in a fine grained way. My understanding with Agile and continuous build is that its there to put pressure on the developers to always have working code. That to break the source tree is a taboo thing to do. Now i agree with both of these sentiments, but it occurs to be that sometimes these might be working against each other. You maybe in the middle of a largish code change and want to commit code to make sure you have history, but this will break the source tree. Anybody got any thoughts on this? Cheers Mark.

• Does it take time to deallocate memory?

  - by jm1234567890

  I have a C++ program which, during execution, will allocate about 3-8Gb of memory to store a hash table (I use tr1/unordered_map) and various other data structures. However, at the end of execution, there will be a long pause before returning to shell. For example, at the very end of my main function I have std::cout << "End of execution" << endl; But the execution of my program will go something like $ ./program do stuff... End of execution [long pause of maybe 2 min] $ -- returns to shell Is this expected behavior or am I doing something wrong? I'm guessing that the program is deallocating the memory at the end. But, commercial applications which use large amounts of memory (such as photoshop) do not exhibit this pause when you close the application. Please advise :)

• Corporate Wiki Organization - Technical Documentation

  - by Dave Jarvis

  Corporations have documents describing various aspects of their technical systems, including: Custom Applications Custom Development Frameworks Third Party Applications Accounting Bug Tracking Network Management How To Guides User Manuals Software Tools Web Browsers Development IDEs Graphics GIMP xv Text Editing File Transfer ncFTP WinSCP Hardware Servers Web Database Exchange File Network Devices Printers What other items are missing from the list, and how would you organize it? (For example, would Software Tools make more sense under Third Party Applications?) Try to think about where you, a software developer, would expect to find the information by browsing (not searching). A few constraints: The structure should not go beyond three levels deep. Avoid the word "and" in favour of two different categories. Keep the structure general: it should appy as broadly as possible. Target audience is primarily technical.

• WebsiteSpark & Visual Studio 2010

  - by Amadiere

  Having a look around at WebsiteSpark from Microsoft - the deal is good (especially if you were looking to go down this path already). But I'm one of those people that likes to 'wait for the next version' if I'm in no rush to sign up. One question that's been bugging me is whether or not the program includes upgrades to Visual Studio and/or they will change the starting pack at some point? Currently, If you sign up now, you get 3 copies of Visual Studio 2008. If you're umming and ahhing about the scheme, is it worth waiting and hoping that they adapt their program so that it comes with VS2010? Or maybe that they'll offer free updates to those already in the scheme? (This question may be a little subjective I guess and it probably applies to the BizSpark side of things as well. Have there been any hints set in other Microsoft programs that might indicate the outcome? ).

• Looking to capture PageIndex on a gridview

  - by StevieB

  Hey, So I have a gridview which lists a bunch of jobs. On this gridview I have paging enabled, which works fine. When I hover over the Page Numbers i.e 1,2,3,4,.... the following is displayed javascript_DoPostBack('C100PlaceHolderGrievew','Page$1') Now my problem is as follows. When I click on one of the hyperlinks in this list i go to an edit details page. Once the user clicks on save I redirect the user back to the List page with gridview. What I would like to implement is that the gridview remembers what page they came from i.e Page 2. I know i can Use PageIndex to set this but Im not sure how to send across the value of "page" of the gridview so i can this.

• why can't I comment lines in visual mode

  - by Haiyuan Zhang

  I want to comment several lines in my .vimrc, the usual way I do it is :x,ys/^/"/ and x stands for the start line number and y stands for the line number of the last line. I read some post which said in visual mode this task can be done by the following step: 1 Select your lines with VISUAL BLOCK 2 press I to insert before all highlighted lines. 3 type your comment charact , in this case should be " 4 then ESC I fllowed the above steps and met met problems in step 2 . the thing is when I select the lines in Visual mode and press I , vim ( I use version7.2) go back to insert mode and the cursor back to the start of the first line. so if you continue to do the step 3 and step 4, you end up in just inserting " at the start the first line , far from what I want to achieve. so could you point out what's wrong with the recipe ? thanks in advance

• Easy to follow LaTeX tutorial on layout?

  - by lexu

  I want to layout a page using LaTeX and distribute text snippets/blocks in predefined locations. Something like this +--------------------------------------------------------+ | +-------------+ | | |bla bla bla| | | |bla bl ab lab| +-------------+ | | |bla bla bla| |bla bla bla| | | |bla bl ab lab| |bla bl ab lab| | | +-------------+ |bla bla bla| | | |bla bl ab lab| | | +-------------+ +----+ | | |more| | | Ich und Du |text| | | Müllers Kuh +----+ | | | +--------------------------------------------------------+ My guess is that I should go about this using a minipage or using boxes like \begin{minipage}[b][2cm]{8cm} \mbox{more} \newline \mbox{text} \newline \end{minipage} Is there a tutorial or a 'how to' page that you know, that shows me how to do this - not a list all LaTeX idioms, I have some books for that. But my books are more focused on command lists, scientific publishing and math ..

• Between a jsf page and a managed bean, why the getter method is called twice

  - by Bariscan

  Hi, I have a jsf page with a form has an outputtext in it. The value of outputtext component is called from a backing bean (or managed bean). I know when I code it as #{MyBean.myString} Jsf rename it and calls getMyString() method. However the wierd thing is, when I put a breakpoint to the getter method of this component, I see it is called twice during the page is being rendered. The outputtext is in a h:form, and it is the only component wich is bind to a backingbean. I mean, it is so wierd that jsf should get the value when it first come to the getter method, however it needs to go to the getter method twice. Can you explain what is the reason of this behaviour in jsf? Any help would be appreciated, Best wishes, Baris

• Android - Using Camera Intent but not updating correctly?

  - by Tyler

  Hello - I am using an intent to capture a picture: Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); i.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File(Environment.getExternalStorageDirectory(), "test.jpg"))); startActivityForResult(i, 2); And then once taken I do the following: sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, Uri.parse("file://" + Environment.getExternalStorageDirectory()))); launchGallery(); While the above seems to work the first time without issue, whenever I run through a second time (so test.jpg already exists) the image actually saves correctly to /sdcard/ but I am finding that the thumbnail does not update and when the gallery loads it shows the previous test.jpg image! I was under the impression that sendBroadcast should update the thumbnails, but it doesn't appear to be.. Is there some other way to go about this and ensure when I call my launchGallery(); method the most recent image I just took appears? Thanks!

• Haskell simple compilation bug

  - by fmsf

  I'm trying to run this code: let coins = [50, 25, 10, 5, 2,1] let candidate = 11 calculate :: [Int] calculate = [ calculate (x+candidate) | x <- coins, x > candidate] I've read some tutorials, and it worked out ok. I'm trying to solve some small problems to give-me a feel of the language. But I'm stuck at this. test.hs:3:0: parse error (possibly incorrect indentation) Can anyone tell me why? I've started with haskell today so please go easy on the explanations. I've tried to run it like: runghc test.hs ghc test.hs but with: ghci < test.hs it gives this one: <interactive>:1:10: parse error on input `=' Thanks

• Using Yii framework, what would be a right way to process an attribute before displaying it using CH

  - by Karolis

  Say I have this line of code in the view. <?php echo CHtml::activeTextField($model,'start_time'); ?> start_time is a UNIX timestamp. When just displaying it in a view I can apply functions like date() on it. Where should I apply the formatting when I'm displaying it in a form, by using the above line of code? (This case of timestamps/dates might be special, but I'm also interested in how would one go about if it wasn't a date and I just want to work with "value in database" < "different representations of the value in different views. Thanks =)

• How to convert an EntityCollection<T> to List<POCOObj>

  - by ggomez

  I have Entity Framework entities Events which have an EntityCollection of RSVP. I want to convert the EntityCollection of RSVP to a generic List< of a POCO class RSVP. So I want EntityCollection - List. What would be the best way to go about achieving this? So far I have this (it's missing the RSVP part) var events = from e in _entities.Event.Include("RSVP") select new BizObjects.Event { EventId = e.EventId, Name = e.Name, Location = e.Location, Organizer = e.Organizer, StartDate = e.StartDate, EndDate = e.EndDate, Description = e.Description, CreatedBy = e.CreatedBy, CreatedOn = e.CreatedOn, ModifiedBy = e.ModifiedBy, ModifiedOn = e.ModifiedOn, RSVPs = ??? }; Thanks.

• Dealing with UIImagePickerController to minimize memory useage

  - by Gordon Fontenot

  So, I have read the SO post on UIImagePickerController, UIImage, Memory and More, and I read the post on Memory Leak Problems with UIImagePickerController in iPhone. I have VASTLY increased my memory efficiency between these 2 posts, and I thank the OPs and the people that provided the answers. I just had a question on the answer provided in the Memory Leak question, which was (essentially): only have one instance of the controller throughout the programs runtime What would be the best way to go about this without causing memory leaks? Right now I am initiating it and releasing it on every use from within the view, and I am seeing exactly what the answer describes (Memory warnings and a crash after about 20 uses). Should I initiate the UIImagePickerController when I need it, but use a seperate class unrelated to the view to control it? How should I deal with releasing the controller if I do it this way?

• django admin app error (Model with property field): global name 'full_name' is not defined

  - by rxin

  This is my model: class Author(models.Model): first_name = models.CharField(max_length=200) last_name = models.CharField(max_length=200) middle_name = models.CharField(max_length=200, blank=True) def __unicode__(self): return full_name def _get_full_name(self): "Returns the person's full name." if self.middle_name == '': return "%s %s" % (self.first_name, self.last_name) else: return "%s %s %s" % (self.first_name, self.middle_name, self.last_name) full_name = property(_get_full_name) Everything is fine except when I go into admin interface, I see TemplateSyntaxError at /bibbase2/admin/bibbase2/author/ Caught an exception while rendering: global name 'full_name' is not defined It seems like the built-in admin app doesn't work with a property field. Is there something wrong with my code?

• Processing potentially large STDIN data, more than once

  - by d11wtq

  I'd like to provide an accessor on a class that provides an NSInputStream for STDIN, which may be several hundred megabytes (or gigabytes, though unlikely, perhaps) of data. When I caller gets this NSInputStream it should be able to read from it without worrying about exhausting the data it contains. In other words, another block of code may request the NSInputStream and will expect to be able to read from it. Without first copying all of the data into an NSData object which (I assume) would cause memory exhaustion, what are my options for handling this? The returned NSInputStream does not have to be the same instance, it simply needs to provide the same data. The best I can come up with right now is to copy STDIN to a temporary file and then return NSInputStream instances using that file. Is this pretty much the only way to handle it? Is there anything I should be cautious of if I go the temporary file route?

• Password Protected Wordpress MU

  - by HollerTrain

  I have a MU site related to Doctors and they will be publishing information that I cannot let outside sources and robots view. Is there a way that when you go to the main domain url, it shows a user/pass login for WP. I would set up the user/pass in the backend. Then they would login, then be able to view the website? I can't have it load up for anyone, I need the website to be password protected to even view the website in general. I know I can use .htaccess to have a user/pass, but it would be ideal to use the user/pass generated by WP so I don't have to mess with code when I create a user. Any help would be greatly appreciated.

• Strategy for Offline/Online data synchronization

  - by Adi

  My requirement is I have server J2EE web application and client J2EE web application. Sometimes client can go offline. When client comes online he should be able to synchronize changes to and fro. Also I should be able to control which rows/tables need to be synchronized based on some filters/rules. Is there any existing Java frameworks for doing it? If I need to implement on my own, what are the different strategies that you can suggest? One solution in my mind is maintaining sql logs and executing same statements at other side during synchronization. Do you see any problems with this strategy?

• Redirect Output of Capistrano

  - by Eric Lubow

  I have a Capistrano deploy file (Capfile) that is rather large, contains a few namespaces and generally has a lot of information already in it. My ultimate goal is, using the Tinder gem, paste the output of the entire deployment into Campfire. I have Tinder setup properly already. I looked into using the Capistrano capture method, but that only works for the first host. Additionally that would be a lot of work to go through and add something like: output << capture 'foocommand' Specifically, I am looking to capture the output of any deployment from that file into a variable (in addition to putting it to STDOUT so I can see it), then pass that output in the variable into a function called notify_campfire. Since the notify_campfire function is getting called at the end of a task (every task regardless of the namespace), it should have the task name available to it and the output (which is stored in that output variable). Any thoughts on how to accomplish this would be greatly appreciated.

• Adding scrollbars to UserControl

  - by Bevin

  I am trying to add vertical and horizontal scrollbars to my UserControl with the HorizontalScroll and VerticalScroll properties, but I am having extreme issues. My problem arises when I drag or manipulate the scroll box on the bar. When I let it go, it simply jumps back to the start position! I know of the AutoScroll property, but I do not want to use it since I want to be able to control every aspect of my scrollbars, and I don't want it to be done automatically. Also, according to the documentation, AutoScroll is for "[enabling] the user to scroll to any controls placed outside of its visible boundaries" which isn't what I want. I just want scrollbars. ...aaand I suppose I could add VScrollBar and HScrollBar to the control, but why should I do this when the scroll functionality already exists? Seems like a waste to me.

• Delphi Search Edit Component

  Hi, I need a delphi component for Delphi 2007 win32 that have features like Google search text box. ** While User writing search key it should fill/refresh the list with values, and user can select one of them. **User can go up and down list and can select one of them. **List should contain codes and text pair, so user can select text and I can get code for database operations. (Google can highlight the search text in List but I think it is not possible with Delphi 2007, so it is not excepted.) I tried Dev Express TcxMRUEdit, however it doesn't meet my needs

• Tarballing without git metadata

  - by zaf

  My source tree contains several directories which are using git source control and I need to tarball the whole tree excluding any references to the git metadata or custom log files. I thought I'd have a go using a combo of find/egrep/xargs/tar but somehow the tar file contains the .git directories and the *.log files. This is what I have: find -type f . | egrep -v '\.git|\.log' | xargs tar rvf ~/app.tar Can someone explain my misunderstanding here? Why is tar processing the files that find and egrep are filtering? I'm open to other techniques as well.
