  • Using PowerShell class to invoke a "[namespace.class]::method" style command

    - by Marco
    Hello, I created a powershell object via .net to invoke commands. When I invoke normal commands like 'Get-Process' I had no problems: ps.AddCommand("Get-Process").AddParameter(...).Invoke() but I'm not able to invoke a .net method with the syntax "[namespace.class]::method", just to make an example to invoke [System.IO.File]::Exists("c:\boo.txt"). I tried with ps.AddCommand("[System.IO.File]::Exists(\"c:\\boo.txt\")").Invoke() ps.AddCommand("[System.IO.File]::Exists").AddArgument("c:\\boo.txt").Invoke() and some others. It always throws an exception which says that the command specified is not recognized. There is a way to invoke that type of command? Thanks

  • Pass data in np.dnarray to Highcharts

    - by F.N.B
    I'm working with python 2.7, jinja2, flask and Highcharts. I create two numpy array (x1 and x2, type = numpy.dnarray) and I pass to Highcharts. My problems is, Highcharts don't recognize the commas in the vector. This is my jinja2 code: <script> $(function () { $('#container').highcharts({ series: [{ name: 'Tokyo', data: {{ x1 }} }, { name: 'London', data: {{ x2 }} }] }); }); And this is the error that I look with network chrome dev tools: series: [{ name: 'Tokyo', data: [1 4 5 2 3] }, { name: 'London', data: [3 6 7 4 1] }] I need change the numpy array to python list to pass to Highcharts or there is a better way to do?? Thanks

  • Xcode debugger showing assembler for nested classes in a static library

    - by Massif
    I have a project A which creates a static library. I have a project B which uses this library. When I am debugging project B, certain functions within project A will display assembler when stepped into or when a breakpoint set inside them is hit. In the debug navigator, the line containing the function is grey instead of black. The strange part is that other functions in the same source file have no problems displaying. The thing that all these functions seem to have in common is that they belong to nested classes. However, I'm not totally convinced that this is the issue since functions from other nested classes display correctly. Does anyone know the cause of this?

  • Using CouchDB to serve HTML.

    - by alxross
    I'm trying to use CouchDB with HTML/standalone REST architecture. That is, no other app server other than CouchDB and ajax style javascript calling CouchDB. It looks like cross scripting is a problem. I was using Cloudkit/Tokyo Cabinet before and it seems like the needed callback function was screwing it up in the URL. Now I'm trying CouchDB and getting the same problem. Here are my questions: 1) Are these problems because the REST/JSON store like CouchDB or CloudKit is running on a different port from my web page? They're both run locally and called from "localhost". 2) Should I let CouchDB host my page and serve the HTML? 3) How do I do this? The documentation didnt seem so clear... Thanks, Alex

  • django: Selecting questions that was not asked

    - by Oleg Tarasenko
    Hi, I am creating small django application which holds some few questions (and answers for them) What I want to do is to show user random question, but only from those which was not solved by him yet. I wonder how to do this. For now, I defined user profile model this way: class UserProfile(models.Model): rank = models.IntegerField(default = 1) solvedQ = models.ManyToManyField(Question) user = models.ForeignKey(User, unique=True) So solved problems are added this way: if user.is_authenticated(): profile = user.get_profile() profile.rank += 1 profile.solvedQ.add(Question.objects.get(id=id)) Now if the view must show random question, but not from already solved list... Is there a good way to intersect Questions and solvedQuestions.... so question is chosen from the unsolved list?

  • Bash script with regex not behaving on Ubuntu

    - by user265330
    I have a Bash script that is working on my OpenSuSE box, but when copied across to my Ubuntu box, is not working. The script reads in from a file. The file has fields separated by white space (tabs and spaces). #!/bin/bash function test1() { while read LINE do if [[ $LINE =~ "^$" || $LINE =~ "^#.*" ]] ; then continue; fi set -- $LINE local field1=$1 local field2=$2 done < test.file } test1 with test.file containing: # Field1Header Field2Header abcdef A-2 ghijkl B-3 There seem to be two problems: (1) $field2, the one with the hyphen, is blank (2) The regex to strip out the blank lines and lines that start with # is not working Anyone know what's wrong? As I said, it works fine on OpenSuSE. Thanks, Paul

  • Weird landscape UITabBarController Application startup

    - by Stefano Verna
    Hi there. My application is quite simple, but I have some problems when it starts. I setted in the Info.plist to be landscaped, but it seems to ignore the order. In fact, when the app is loading the Simulator is landscaped, but then it returns in portrait mode. This is the hierarchy of the views and controllers: MainViewController (extends UITabBarController just to override shouldAutorotateToInterfaceOrientation:) Three extended UITableViewControllers as tabs (also those have the shouldAutorotateToInterfaceOrientation correctly setted up). If I kinda force the orientation of the device to Landscape with: [[UIDevice currentDevice] setOrientation: UIInterfaceOrientationLandscapeRight]; Then for an instant the Simulator flashes in portrait mode, and then it goes landscaped. The problem is that in this way, the auto-rotation animations gets started, which is something I cannot tollerate. I just want a fixed, landscaped application. Any clues? Am I missing something?

  • iPhone SDK - Display more information about a selected CustomCell (custom UITableViewCell)

    - by Pittor
    If got a CustomCell loaded using: NSArray *nibObjects = [[NSBundle mainBundle] loadNibNamed:@"CustomCell" owner:nil options:nil]; I have no problems with the tableview but when I select a row I want display more information on that row(like facebook app)... using the typical "show more". At the beginning the row show "title" and "description". When I select that row i want to show "title", "description" and a webview... and, of course, make the row bigger to accommodate that objects. Maybe changing this CustomCell by another bigger CustomCell? I have no idea where to start. Thanks. Sorry for my english :S

  • 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?

  • Best ways to reuse Java methods

    - by carillonator
    I'm learning Java and OOP, and have been doing the problems at Project Euler for practice (awesome site btw). I find myself doing many of the same things over and over, like: checking if an integer is prime/generating primes generating the Fibonacci series checking if a number is a palindrome What is the best way to store and call these methods? Should I write a utility class and then import it? If so, do I import a .class file or the .java source? I'm working from a plain text editor and the Mac terminal. Thanks!

  • LINQ saving images to varbinary

    - by m4rc
    I'm having issues saving images to a varbinary(Max) field using LINQ. I can save files in the region of 10KB to the database no problems, but when it comes to files bigger than that, it's as though it doesn't even try. I've had a look in the SQL Server Profiler and when the file is around 10KB I can see the full insert statement in the detail pane. However, when the file is a bit bigger, the detail pane doesn't show anything, although any data besides the varbinary field is written to the database. The data is in the Data Object just before SubmitChanges so I can't figure out what's happening between now and then!

  • VIsual Studio 2010 Web Performance Test / Load tests / Coded UI Tests. ANYONE REALLY USE THESE?

    - by punkouter
    I can find some articles on how to use them but I can't seem to find anywhere peoples impression of them using them in real projects. I have been trying to figure out how to use them and Ive had alot of problems.. Can someone out there who uses these tools on the job give me thier impression? Are there better alternate tools available? Using these really just a waste of time ? With Coded UI Tests I see how they are good for basic javascript checking but its so basic of a example I don't think it is worth it. With web tests I like how they work but when I activate code coverage/ASP.NET profiling it doesnt work half the time.

  • Large Video Uploads via a website

    - by Andrew
    Some of the problems that can happen are timeouts, disconnections, and not being able to resume a file and having to start from the beginning. Assuming these files are up to around 5gigs in size, what is the best solution for dealing with this problem? I'm using a Drupal 6 install for the website. Some of my constraints due to the server setup I have to deal with: Shared hosting with max 200 connections at a time (unlimited disk space) Shared hosting. Unable to create users through an API (so can't automatically generate ftp accounts) I do have the ability to run cron-type scripts via a Drupal module. My initial thought was to create ftp users based off of Drupal accounts and requiring them to download an ftp client for their OS of choice. But the lack of API to auto-create ftp accounts and the inability to do it from command line kind of hinder that solution. If there's a workaround someone can think of, let me know! Thanks

  • How to save derived type (TPT) in Entity Framework?

    - by Peter Stegnar
    I have problems with saving derived type (TPT) with Entity Framework to database. Let's say I have base entity Animal and derived type Dog. I want to save Dog entity. I thought that I could do it like contex.AddToDogs(), but contex contain only base entity - Animal. So I can only save Animal object - contex.AddToAnimals(). I have also tried with contex.AddObject("Animals", dogInstance), but I get the following error: The member with identity 'NavigationProperty' does not exist in the metadata collection. But I have add EntityReference to the "NavigationProperty". So how to save derived type in EF?

  • WPF Labels look fine in XP, but are cut off at the bottom in Vista and Windows 7.

    - by juharr
    The following xaml looks fine in XP, but the bottom of the text gets cut off in Vista and Windows 7. <Grid> <Border Height="86" Margin="10,54,10,0" VerticalAlignment="Top" BorderBrush="Black" BorderThickness="1"/> <Label Height="22" Width="100" Margin="15,43,0,0" VerticalAlignment="Top" HorizontalAlignment="Left" Background="White">Text Over Border</Label> </Grid> I realize that I could just increase the Height of the label, but I'm guessing I'll have problems with systems that have different resolution settings, or large text settings. Is there a better way to lay this out?

  • What do you enjoy about programming?

    - by Earlz
    Some of us here(or is it just me?) enjoy programming. Even if we're not being paid for it, and in some cases, even though the end result will not do anything for us. For example, many people do the Project Euler problems just for fun, and in the end nothing was really "accomplished" materially. What is it that makes us enjoy programming? How is programming different from another job? You don't see an accountant going home to do some accounting on their own time just for the pure joy of it. How are we different? (also, if anyone has some ideas on how to tag this, then please do correct it for me.. )

  • Preferred menus for C# application.

    - by SeaDrive
    Which of the menu tools do you use for C# windows applications? I began with MainMenu, but when I moved to VS2005, only MenuStrip appeared in the Toolbox, so I assumed it was new and better. However, the merge/replace action seems to require a lot more time and effort, and leave one open to maintenance problems. (Perhaps my real question is "what were they thinking when they created MenuStrip?) Do you drag/drop the menus, or do you write the code? Do you use MainMenu, MenuStrip, or some other alternatives?

  • Programming cookbook? [closed]

    - by user73669
    Possible Duplicate: What is the single most influential book every programmer should read? Hello With sites like The Daily WTF and recurring threads on Slashdot and elsewhere about bad programming, I figured that, to avoid people reinventing the wheel (badly or not), there should be a good, fat book on programming that would go through typical programming problems and show good, known algorithms, either in pseudo-code or some language with an easy syntax so that the language is not an issue. Here's the list of books on the subject I saw at my local computer bookstore. Can you recommend a couple, or add to this list if it's missing better options? The art of computer programming Code complete Masterminds of programming 97 things every programmer should know The passionate programmer Pragmatic thinking & learning Coders at work The algorithm design manual Algorithms and programming How to think about algorithms How to think like a programmer Why programs fail Beautiful data Beautiful code The productive programmer Solid code Write great code Clean code Programming language pragmatics Hello world Learning Processing Learn to program Thank you.

  • Are static delegates thread-safe?

    - by leypascua
    Consider this code snippet: public static class ApplicationContext { private static Func<TService> Uninitialized<TService>() { throw new InvalidOperationException(); } public static Func<IAuthenticationProvider> AuthenticationProvider = Uninitialized<IAuthenticationProvider>(); public static Func<IUnitOfWorkFactory> UnitOfWorkFactory = Uninitialized<IUnitOfWorkFactory>(); } //can also be in global.asax if used in a web app. public static void Main(string[] args) { ApplicationContext.AuthenticationProvider = () => new LdapAuthenticationProvider(); ApplicationContext.UnitOfWorkFactory = () => new EFUnitOfWorkFactory(); } //somewhere in the code.. say an ASP.NET MVC controller ApplicationContext.AuthenticationProvider().SignIn(username, true); Are delegates in the static class ApplicationContext thread-safe in the sense that multiple-threads can invoke them? What potential problems will I face if I pursue this approach?

  • SQL Server Service Broker Service Disappearing (Automatically Deleted)?

    - by mwigdahl
    I've implemented a messaging system over SQL Server Service Broker. It is working great, with the sole exception that every once in a while (maybe once per week per server) my initiator service just vanishes without a trace. The corresponding queue is still there, but the service is missing. Obviously this causes problems in my system. It's a simple matter to recreate the service by hand, but I'm confused as to what might cause this behavior. I understand that automatic poison message handling causes queues to be disabled, but I don't see anything that indicates services can be disabled or deleted automatically. When this happens, I usually have a large backlog of messages in multiple application queues, but nothing extreme. Total message backlog is around 200,000. Does anyone know what might be happening here?
