  • Multiple CodeSnippet in an XML .snippet file

    - by Frinavale
    I'm attempting to supplement the help features for my code by providing other developers with code snippets. These produce skeletons of code which demonstrate how to use/call my classes or methods. I've created a .snippet file and have placed it in the "%Visual Studio Folder%\Code Snippets\Visual Basic\My Snippets" folder. I've used the Code Snippets Manager and ensured that it included this folder so that I can access the snippets. Everything works well when I have 1 CodeSnippet tag within the root CodeSnippets tag.... When I add more than one CodeSnippet tag to the file (each with their own title, and their own code example) I'm experiencing something strange. The first CodeSnippet I've added contains code for adding something to my system, the second contains code for editing something in my system, and the third deleting something from the system. When I use the code snippet by right clicking and selecting "Insert Code Snippet", only the first code snippet in the file shows up as an option. When I select it, the code in the first CodeSnippet is inserted....but so is the code within the other CodeSnippet tags. Do you have to have a separate XML .snippet file for each code snippet you want to make available? After reading through MSDN about creating Code Snippets I was under the impression that this could all be done within one file. It seems that I'm not understanding something very basic here and would love to find the answer but apparently Code Snippets are under used so finding the answer has proven to be a little trickier than I first thought it would be. Thanks, -Frinny

  • SQL Server slow in production environment

    - by Lieven Cardoen
    I have a weird problem in a customer's production environment. I can't give any details on the infrastructure, except that SQL server runs on a virtual server. The data, log and filestream file are on another storage server (data and filestream together and log on a separate server). In our local Test environment, there's one particular query that executes with these durations: first we clear the cache 300ms (First time it takes longer, but from then on it's cached.) 20ms 15ms 17ms In the customer's production environment, the SQL Server is more powerful, these are the durations (I didn't have the rights to clear the cache. Will try this tomorrow). 2500ms 2600ms 2400ms The servers in the customer's production environment are more powerful but they do have virtual servers (we don't). What could be the cause... Not enough memory? Fragmentation? Physical storage? How would you tackle this performance problem? EDIT: Some people have asked me if the data set is equal and it is. I restored their database on our environment. It's true that this was the first thing I looked at. (@Everyone: I added the edit because it will be the first thing that many will think off).

  • Algorithm to get through a maze

    - by Sam
    Hello, We are currently programming a game (its a pretty unknown language: modula 2), And the problem we encountered is the following: we have a maze (not a perfect maze) in a 17 x 12 grid. The computer has to generate a way from the starting point (9, 12) to the end point (9, 1). I found some algorithms but they dont work when the robot has to go back: xxxxx x => x x xxx or: xxxxx x xxxxxx x x x x x xxxxxx x => x xxxxxxxxx I found a solution for the first example type but then the second type couldn't be solved and the solution I made up for the second type would cause the robot to get stuck in the first type of situation. It's a lot of code so i'll give the idea: WHILE (end destination not reached) DO { try to go right, if nothing blocks you: go right if you encounter a block, try up until you can go right, if you cant go up anymore try going down until you can go right, (starting from the place you first were blocked), if you cant go down anymore, try one step left and fill the spaces you tested with blocks. } This works for the first type of problem ... not for the second one. Now it could be that i started wrong so i am open for better algorithms or solutions specificaly to how i could improve my algorithm. Thanks a lot!!

  • Threading best practice when using SFTP in C#

    - by Christian
    Ok, this is more one of these "conceptual questions", but I hope I got some pointers in the right direction. First the desired scenario: I want to query an SFTP server for directory and file lists I want to upload or download files simulaneously Both things are pretty easy using a SFTP class provided by Tamir.SharpSsh, but if I only use one thread, it is kind of slow. Especially the recursion into subdirs gets very "UI blocking", because we are talking about 10.000 of directories. My basic approach is simple, create some kind of "pool" where I keep 10 open SFTP connections. Then query the first worker for a list of dirs. If this list was obtained, send the next free workers (e.g. 1-10, first one is also free again) to get the subdirectory details. As soon as there is a worker free, send him for the subsubdirs. And so on... I know the ThreadPool, simple Threads and did some Tests. What confuses me a little bit is the following: I basically need... A list of threads I create, say 10 Connect all threads to the server If a connection drops, create a new thread / sftp client If there is work to do, take the first free thread and handle the work I am currently not sure about the implementation details, especially the "work to do" and the "maintain list of threads" parts. Is it a good idea to: Enclose the work in an object, containing a job description (path) and a callback Send the threads into an infinite loop with 100ms wait to wait for work If SFTP is dead, either revive it, or kill the whole thread and create a new one How to encapsulate this, do I write my own "10ThreadsManager" or are there some out Ok, so far... Btw, I could also use PRISM events and commands, but I think the problem is unrelated. Perhaps the EventModel to signal a done processing of a "work package"... Thanks for any ideas, critic.. Chris

  • Selector and Iterating Through a Table Within a Div

    - by GregH
    I have been working on this and cannot get this iterator to work. I have the following HTML and am trying to iterate through all rows (except the first row) and extract the values in cells (td) 2 and 3 : <div id="statsId"> <table width="220" cellspacing="0" cellpadding="0" border="0"> <tbody> <tr> <td width="65"/> <td width="90"/> <td width="65"/> </tr> <tr style="font-weight: bold;"> <td align="left">$1.00</td> <td> <a href="#">UserID1</a> </td> <td>Single</td> </tr> <tr> <td align="left">$6.99</td> <td> <a href="#">UserID2</a> </td> <td>Multiple</td> </tr> <tr>... .....(snip) I tried the following iterator to iterate through all except the first row of the table that is a child of "div#statsID" and get the values of the 2nd and 3rd cells (in the example, the first extracted cells would have values of "UserID1" and "Single"), but it doesn't work. $('div#statsId > table tr:not(:nth-child(1))').each(function(i, ele) { var secondCol = $('td:nth-child(2)', ele).innerHTML var thirdCol= $('td:nth-child(3)', ele).text() ..... }); Any suggestions on how to specify and iterate through the rows (except the first) of a table that is a child of a div would be appreciated.

  • Designing a fluid Javascript interface to abstract away the asynchronous nature of AJAX

    - by Anurag
    How would I design an API to hide the asynchronous nature of AJAX and HTTP requests, or basically delay it to provide a fluid interface. To show an example from Twitter's new Anywhere API: // get @ded's first 20 statuses, filter only the tweets that // mention photography, and render each into an HTML element T.User.find('ded').timeline().first(20).filter(filterer).each(function(status) { $('div#tweets').append('<p>' + status.text + '</p>'); }); function filterer(status) { return status.text.match(/photography/); } vs this (asynchronous nature of each call is clearly visible) T.User.find('ded', function(user) { user.timeline(function(statuses) { statuses.first(20).filter(filterer).each(function(status) { $('div#tweets').append('<p>' + status.text + '</p>'); }); }); }); It finds the user, gets their tweet timeline, filters only the first 20 tweets, applies a custom filter, and ultimately uses the callback function to process each tweet. I am guessing that a well designed API like this should work like a query builder (think ORMs) where each function call builds the query (HTTP URL in this case), until it hits a looping function such as each/map/etc., the HTTP call is made and the passed in function becomes the callback. An easy development route would be to make each AJAX call synchronous, but that's probably not the best solution. I am interested in figuring out a way to make it asynchronous, and still hide the asynchronous nature of AJAX.

  • Good ways to dynamically generate the start image of an iPhone/iPad app

    - by Dr Dork
    I'm self-learning iPhone development and I see that one of the aspects of an iPhone/iPad app is the start image that gets displayed when your app is run. I'd like my start image to display some basic info about the user when the app is launched, but that info has to first be collected by the user when the app is first run. That tells me that I either need to dynamically generate the start image after the user enters their information or I need to place a label of some sort on top of my static start image in order to accomplish this. The first time the app launched and before the user enters their info, the start image can be anything or nothing at all, I'm not concerned about this. So, my two questions are this... Can you place controls, like a label, on top of the start image when your app is launched? If not, what's a good approach to dynamically generating the start image after the app is launched for the first time and the user info is collected? Thanks so much in advance for your help! I'm going to begin researching this question right now.

  • Maths Question: number of different permutations

    - by KingCong
    This is more of a maths question than programming but I figure a lot of people here are pretty good at maths! :) My question is: Given a 9 x 9 grid (81 cells) that must contain the numbers 1 to 9 each exactly 9 times, how many different grids can be produced. The order of the numbers doesn't matter, for example the first row could contain nine 1's etc. This is related to Sudoku and we know the number of valid Sudoku grids is 6.67×10^21, so since my problem isn't constrained like Sudoku by having to have each of the 9 numbers in each row, column and box then the answer should be greater than 6.67×10^21. My first thought was that the answer is 81! however on further reflection this assume that the 81 number possible for each cell are different, distinct number. They are not, there are 81 possible numbers for each cell but only 9 possible different numbers. My next thought was then that each of the cells in the first row can be any number between 1 and 9. If by chance the first row happened to be all the same number, say all 1s, then each cell in the second row could only have 8 possibilites, 2-9. If this continued down until the last row then number of different permutations could be calculated by 9^2 * 8^2 * 7^2 ..... * 1^2. However this doesn't work if each row doesn't contain 9 of the same number. It's been quite a while since I studied this stuff and I can't think of a way to work it out, I'd appreciate any help anyone can offer.

  • GAE Task Queue oddness

    - by b3nw
    I have been testing the taskqueue with mixed success. Currently I am using the default queue, in default settings ect ect.... I have a test url setup which inserts about 8 tasks into the queue. With short order, all 8 are completed properly. So far so good. The problem comes up when I re-load that url twice under say a minute. Now watching the task queue, all the tasks are added properly, but only the first batch execute it seems. But the "Run in Last Minute" # shows the right number of tasks being run.... The request logs tell a different story. They show only the first set of 8 running, but all task creation urls working successfully. The oddness of this is that if I wait say a minute between the task creation url requests, it will work fine. Oddly enough changing the bucket_size or execution speed does not seem to help. Only the first batch are executed. I have also reduced the number of requests all the way down to 2, and still found only the first 2 execute. Any others added display the same issues as above. Any suggestions? Thanks

  • jQuery fadein fadeout divs over set interval

    - by theDawckta
    I want to fadeOut the first div in a collection and then fadeIn the next div. The fade in out would trigger at a set time. The number of items in the collection is 1 to n. Here is an example of the html; <div class="contentPanel"> <div class="content"> <div style="border: solid 2px black; text-align: center"> This is first content </div> </div> <div class="content"> <div style="border: solid 2px black; text-align: center"> This is second content </div> </div> <div class="content"> <div style="border: solid 2px black; text-align: center"> This is third content </div> </div> </div> So on page load the first "content" class would be visible, after x amount of time, the current "content" would fadeout and the next "content" would fade in. When it got to the nth "content" it would start over, fadeout the nth "content" and fadein the first "content". This behavior would loop continuously.

  • Getting Vars to bind properly across multiple files

    I am just learning Clojure and am having trouble moving my code into different files.

  • Address Match Key Algorithm

    - by sestocker
    I have a list of addresses in two separate tables that are slightly off that I need to be able to match. For example, the same address can be entered in multiple ways: 110 Test St 110 Test St. 110 Test Street Although simple, you can imagine the situation in more complex scenerios. I am trying to develop a simple algorithm that will be able to match the above addresses as a key. For example. the key might be "11TEST" - first two of 110, first two of Test and first two of street variant. A full match key would also include first 5 of the zipcode as well so in the above example, the full key might look like "11TEST44680". I am looking for ideas for an effective algorithm or resources I can look at for considerations when developing this. Any ideas can be pseudo code or in your language of choice. We are only concerned with US addresses. In fact, we are only looking at addresses from 250 zip codes from Ohio and Michigan. We also do not have access to any postal software although would be open to ideas for cost effective solutions (it would essentially be a one time use). Please be mindful that this is an initial dump of data from a government source so suggestions of how users can clean it are helpful as I build out the application but I would love to have the best initial I possibly can by being able to match addresses as best as possible.

  • Accessing Attributes in a Many-to-Many

    - by tshauck
    Hi, I have a rails app and I'd like to be able to do something like task.labels.first.label_name to get the label name of a task. However, I get an undefined method label_name. I did a t = Task.first; t.labels.first.label_name in the console, and that worked so I'm not sure what's going on. Here's the models then the locations of the error: class Categorization < ActiveRecord::Base belongs_to :label belongs_to :task end class Label < ActiveRecord::Base attr_accessible :label_name has_many :categorizations has_many :tasks, :through => :categorizations end class Task < ActiveRecord::Base attr_accessible :task has_many :categorizations has_many :labels, :through => :categorizations end The error is in the index <% for task in @tasks %> <tr> <td><%= task.task %></td> <td><%= task.labels.first.label_name %></td> <td><%= link_to "Show", task %></td> <td><%= link_to "Edit", edit_task_path(task) %></td> <td><%= link_to "Destroy", task, :confirm => 'Are you sure?', :method => :delete %></td> </tr> <% end %

  • Metamorphs Messing Up CSS in Ember.js Views

    - by Austin Fatheree
    I'm using Ember.js / handlebars to loop through a collection and spit out some items that I'd like bootstrap to handle nice and responsive like. Here is the issue: The bootstrap-responsive css has some declrations in it like: .row-fluid > [class*="span"]:first-child { margin-left: 0; } and .row-fluid:before, .row-fluid:after { display: table; content: ""; } These rules seem to target the first children. When I loop through my collection in handlebars I end up with a bunch of metamorph code around my items: <div class="row-fluid"> {{#each restaurantList}} {{view GS.vHomePageRestList content=this class="span6"}} {{/each}} </div> Here is what is produced: <div class="row-fluid"> <script id="metamorph-9-start" type="text/x-placeholder"></script> <script id="metamorph-104-start" type="text/x-placeholder"></script> <div id="ember2527" class="ember-view span6"> My View </div> <script id="metamorph-104-end" type="text/x-placeholder"></script> <script id="metamorph-105-start" type="text/x-placeholder"></script> <div id="ember2574" class="ember-view span6"> My View 2 </div> <script id="metamorph-105-end" type="text/x-placeholder"></script> <script id="metamorph-9-end" type="text/x-placeholder"></script> </div> So my question is this: 1. How can I tell css to ignore script tags? or 2. How can I edit the css bindings so that they skip over script tags when selecting the first or first child? or 3. How can I structure this so that Ember uses fewer/no metamorph tags? Here is a fiddle: http://jsfiddle.net/skilesare/SgwsJ/

  • Getting text between quotes using regular expression

    - by Camsoft
    I'm having some issues with a regular expression I'm creating. I need a regex to match against the following examples and then sub match on the first quoted string: Input strings ("Lorem ipsum dolor sit amet, consectetur adipiscing elit.") ('Lorem ipsum dolor sit amet, consectetur adipiscing elit. ') ('Lorem ipsum dolor sit amet, consectetur adipiscing elit. ', 'arg1', "arg2") Must sub match Lorem ipsum dolor sit amet, consectetur adipiscing elit. Regex so far: \((["'])([^"']+)\1,?.*\) The regex does a sub match on the text between the first set of quotes and returns the sub match displayed above. This is almost working perfectly, but the problem I have is that if the quoted string contains quotes in the text the sub match stops at the first instance, see below: Failing input strings ("Lorem ipsum dolor \"sit\" amet, consectetur adipiscing elit.") Only sub matches: Lorem ipsum dolor ("Lorem ipsum dolor 'sit' amet, consectetur adipiscing elit.") The entire match fails. Notes The input strings are actually php code function calls. I'm writing a script that will scan .php source files for a specific function and grab the text from the first parameter.

  • WPF/SL EventAggregator implementation with durable subscribers behavior?

    - by sha1dy
    Hi. Currently I'm building an application using latest Prism for Silverlight 4. I've a module and in that module I've two views with view models. Also I've a module view with two regions for each view. In module initialization I'm registering my views and view models in Unity container and also register views with corresponding regions. The problem is that views should display something similar to table-detail information - first view shows available entities ans the second view shows detail of selected entity. I need a way how to pass them initial selected entity. Newly created first view doesn't have any selected entity and newly created second view doesn't show any details. Currently I'm doing that this way: In module I create two view models and register them as instances in Unity container and then I register views as types for corresponding regions. Each view subscribes to EntitySelectedEvent from EventAggregator. Module initializer publish this event after initialization and this way two views are selecting the same entity. I know this looks ugly - I tried publishing this event from one of view models but the problems is that EventAggregator in Prism doesn't support durable subscribers - this means that if the second view model didn't subscribe to event before the first view model fired it, it won't receive and event. I know this is a normal behavior of EventAggregator, but I'm looking for a solution when view models can fire events without depending on initialization order of them - that is the first model can fire event before the second model was created and the second model will receive this 'queued' event after subscribing to it. Are there any other messaging implementations for WPF/SL which do support such behavior or using a mediator (in my example it's a module itself) isn't such a bad idea after all? One big problem with mediator is that models must be created right away in initialize and they can't be registered as types in container because this leads again to missing subscribers.

  • Autodetect Presence of CSV Headers in a File

    - by banzaimonkey
    Short question: How do I automatically detect whether a CSV file has headers in the first row? Details: I've written a small CSV parsing engine that places the data into an object that I can access as (approximately) an in-memory database. The original code was written to parse third-party CSV with a predictable format, but I'd like to be able to use this code more generally. I'm trying to figure out a reliable way to automatically detect the presence of CSV headers, so the script can decide whether to use the first row of the CSV file as keys / column names or start parsing data immediately. Since all I need is a boolean test, I could easily specify an argument after inspecting the CSV file myself, but I'd rather not have to (go go automation). I imagine I'd have to parse the first 3 to ? rows of the CSV file and look for a pattern of some sort to compare against the headers. I'm having nightmares of three particularly bad cases in which: The headers include numeric data for some reason The first few rows (or large portions of the CSV) are null There headers and data look too similar to tell them apart If I can get a "best guess" and have the parser fail with an error or spit out a warning if it can't decide, that's OK. If this is something that's going to be tremendously expensive in terms of time or computation (and take more time than it's supposed to save me) I'll happily scrap the idea and go back to working on "important things". I'm working with PHP, but this strikes me as more of an algorithmic / computational question than something that's implementation-specific. If there's a simple algorithm I can use, great. If you can point me to some relevant theory / discussion, that'd be great, too. If there's a giant library that does natural language processing or 300 different kinds of parsing, I'm not interested.

  • iPhone: addAnnotation not working when called from another view

    - by Nic Hubbard
    I have two views, the first view has an MKMapView on it named ridesMap. The second view is just a view with a UITableView in it. When you click the save button in the second view, it calls a method from the first view: // Get my first views class MyRidesMapViewController *rideMapView = [[MyRidesMapViewController alloc] init]; // Call the method from my first views class that removes an annotation [rideMapView addAnno:newRidePlacemark.coordinate withTitle:rideTitle.text withSubTitle:address]; This correctly calls the addAnno method, which looks like: - (void)addAnno:(CLLocationCoordinate2D)anno withTitle:(NSString *)annoTitle withSubTitle:(NSString *)subTitle { Annotation *ano = [[[Annotation alloc] init] autorelease]; ano.coordinate = anno; ano.title = annoTitle; ano.subtitle = subTitle; if ([ano conformsToProtocol:@protocol(MKAnnotation)]) { NSLog(@"YES IT DOES!!!"); } [ridesMap addAnnotation:ano]; }//end addAnno This method creates an annotation which does conform to MKAnnotation, and it suppose to add that annotation to the map using the addAnnotation method. But, the annotation never gets added. I NEVER get any errors when the annotation does not get added. But it never appears when the method is called. Why would this be? It seems that I have done everything correctly, and that I am passing a correct MKAnnotation to the addAnnotation method. So, I don't get why it never drops a pin? Could it be because I am calling this method from another view? Why would that matter?

    I'm working with cucumber and I'm running into difficulties. When I run "cucumber features", I am met with errors, cucumber is unable to find my requests table. What obvious mistake am I making? Thank you in advance!

  • Best pratice: How do I implement a list that can be rendered both server-side and client-side?

    - by André Pena
    Technologies involved: ASP.NET Web-forms Javascript (jQuery for instance) Case To make it clearer let's give the Stackoverflow authors list as an example. This list can be manipulated at client-side. I can search, page and so forth. So obviously we would need to call jQuery.ajax to retrieve the HTML of each page given a search. Alright. Now this leaves me with the first question: What is the best way to render the response for the jQuery.ajax at server-side? I can't use templates I suppose, so the most obvious solution I think is to create the HTML tags as server-controls and render them as the result of an ASHX request? Is this is best approach? Nice. That solved we have yet another problem: When the user first enters the Authors List the first list page should already come from the server completely rendered alright? Of course we could render the first page as well as an ajax call but I don't think it's better. This time I CAN use templates to render the list but this template couldn't be reused in case 1. What do I do? Now the final question: Now we have 2 rendering strategies: 1) Client and 2) Server. How do I reuse code for the 2 renderings? What are the best pratices for solving these problems?

  • Designing a fluent Javascript interface to abstract away the asynchronous nature of AJAX

    - by Anurag
    How would I design an API to hide the asynchronous nature of AJAX and HTTP requests, or basically delay it to provide a fluid interface. To show an example from Twitter's new Anywhere API: // get @ded's first 20 statuses, filter only the tweets that // mention photography, and render each into an HTML element T.User.find('ded').timeline().first(20).filter(filterer).each(function(status) { $('div#tweets').append('<p>' + status.text + '</p>'); }); function filterer(status) { return status.text.match(/photography/); } vs this (asynchronous nature of each call is clearly visible) T.User.find('ded', function(user) { user.timeline(function(statuses) { statuses.first(20).filter(filterer).each(function(status) { $('div#tweets').append('<p>' + status.text + '</p>'); }); }); }); It finds the user, gets their tweet timeline, filters only the first 20 tweets, applies a custom filter, and ultimately uses the callback function to process each tweet. I am guessing that a well designed API like this should work like a query builder (think ORMs) where each function call builds the query (HTTP URL in this case), until it hits a looping function such as each/map/etc., the HTTP call is made and the passed in function becomes the callback. An easy development route would be to make each AJAX call synchronous, but that's probably not the best solution. I am interested in figuring out a way to make it asynchronous, and still hide the asynchronous nature of AJAX.

  • UITableView and UITableCellView, how does this work with core plot ?

    - by Luc
    Hello, I'm very new to iPhone programming, and I'm currently following tutos to understand the whole thing. I've been able to do what I needed (retrive data from a JSON http server, parse them with YAJL and plot the data in core plot). I have done this in a "simple" view where I have added a UILayerHostingView as requested by core-plot. I am now trying to follow this tuto: http://blogs.remobjects.com/blogs/mh/2010/01/26/p973 but I am missing the first part regarding the views... My understanding is that I need to create a view with a UITableView first. Then add a UITableCellView to make the first cell be able to contain the graph ? Is this right ? Where does the method "(id)initWithStyle:(UITableViewCellStyle)style" come from ? For my needs, only the first cell needs to contain a graph, I will put some other info in the other cells. As for now, I have created a new GraphListViewController, in the corresponding view I have added a listview but I do not see any auto generated methods regading cell customisation ? Do I need to implements DataSource in this controller and manually add some customisation methods ? Do I need to add a UITagbleViewCell to this UITableViewTable within IB ? Hope I am not getting to confusing... Thanks a lot for your help, Best Regards, Luc
