  • Fixing permissions after FTPing ASP.NET code to a Linux system

    - by dnord
    First off, I'm running Mono to run ASP.NET on Linux, but that's not the question. It appears that, every time I clear out my application directory and upload, I have to go back in and fix the permissions. What I'm doing is chmod -R -c 755 /var/www/* ...and there are two questions. What's the deal with having to do this every time I FTP? Feels flaky. Is there a better permissions set than 755? Do I want different permissions for the /bin directory? Or can I fix this all with one fell swoop of chown?

  • Execute process conditionally in Windows PowerShell (e.g. the && and || operators in Bash)

    - by Dustin
    I'm wondering if anybody knows of a way to conditionally execute a program depending on the exit success/failure of the previous program. Is there any way for me to execute a program2 immediately after program1 if program1 exits successfully without testing the LASTEXITCODE variable? I tried the -band and -and operators to no avail, though I had a feeling they wouldn't work anyway, and the best substitute is a combination of a semicolon and an if statement. I mean, when it comes to building a package somewhat automatically from source on Linux, the && operator can't be beaten: # Configure a package, compile it and install it ./configure && make && sudo make install PowerShell would require me to do the following, assuming I could actually use the same build system in PowerShell: # Configure a package, compile it and install it .\configure ; if ($LASTEXITCODE -eq 0) { make ; if ($LASTEXITCODE -eq 0) { sudo make install } } Sure, I could use multiple lines, save it in a file and execute the script, but the idea is for it to be concise (save keystrokes). Perhaps it's just a difference between PowerShell and Bash (and even the built-in Windows command prompt which supports the && operator) I'll need to adjust to, but if there's a cleaner way to do it, I'd love to know.

  • Facing error in apple multitasking code

    - by user366584
    Actually I am working for multitasking and facing error please assist me, as I need to work on background application and also in foreground application - (void)applicationDidEnterBackground:(UIApplication *)application { UIApplication* app = [UIApplication sharedApplication]; // Request permission to run in the background. Provide an // expiration handler in case the task runs long. NSAssert(bgTask == UIBackgroundTaskInvalid, nil); bgTask = [app beginBackgroundTaskWithExpirationHandler:^{ // Synchronize the cleanup call on the main thread in case // the task actually finishes at around the same time. dispatch_async(dispatch_get_main_queue(), ^{ if (bgTask != UIBackgroundTaskInvalid) { [app endBackgroundTask:bgTask]; bgTask = UIBackgroundTaskInvalid; } }); }]; // Start the long-running task and return immediately. dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{ // Do the work associated with the task. // Synchronize the cleanup call on the main thread in case // the expiration handler is fired at the same time. dispatch_async(dispatch_get_main_queue(), ^{ if (bgTask != UIBackgroundTaskInvalid) { [app endBackgroundTask:bgTask]; bgTask = UIBackgroundTaskInvalid; } }); }); }

  • Rails: How to produce 404 or redirect upon undesired url exploitation?

    - by Baby Diego
    I want to hide the urls for editing users and their profiles behind safer and meaningful urls. For instance, I want /user/13/edit to be /settings/account and /user/13/profile/edit to be /settings/profile. I managed to achieve that, but for that I had to load the user information from the current_user bit from the session. Like so: # users_controller def edit @user = current_user end # profiles_controller def edit @user = current_user @profile = @user.profile end But now, since I can't compare @user.id from the params with the current_user in the session, how can I stop the old urls (/user/13/edit and /user/13/profile/edit) from being exploitable? They always load the forms for the current user, so there's no harm done, but I'd be more comfortable if they just produced a 404 error or something. Thanks in advance.

  • How can I implement NotOfType<T> in LINQ that has a nice calling syntax?

    - by Lette
    I'm trying to come up with an implementation for NotOfType, which has a readable call syntax. NotOfType should be the complement to OfType<T> and would consequently yield all elements that are not of type T My goal was to implement a method which would be called just like OfType<T>, like in the last line of this snippet: public abstract class Animal {} public class Monkey : Animal {} public class Giraffe : Animal {} public class Lion : Animal {} var monkey = new Monkey(); var giraffe = new Giraffe(); var lion = new Lion(); IEnumerable<Animal> animals = new Animal[] { monkey, giraffe, lion }; IEnumerable<Animal> fewerAnimals = animals.NotOfType<Giraffe>(); However, I can not come up with an implementation that supports that specific calling syntax. This is what I've tried so far: public static class EnumerableExtensions { public static IEnumerable<T> NotOfType<T>(this IEnumerable<T> sequence, Type type) { return sequence.Where(x => x.GetType() != type); } public static IEnumerable<T> NotOfType<T, TExclude>(this IEnumerable<T> sequence) { return sequence.Where(x => !(x is TExclude)); } } Calling these methods would look like this: // Animal is inferred IEnumerable<Animal> fewerAnimals = animals.NotOfType(typeof(Giraffe)); and // Not all types could be inferred, so I have to state all types explicitly IEnumerable<Animal> fewerAnimals = animals.NotOfType<Animal, Giraffe>(); I think that there are major drawbacks with the style of both of these calls. The first one suffers from a redundant "of type/type of" construct, and the second one just doesn't make sense (do I want a list of animals that are neither Animals nor Giraffes?). So, is there a way to accomplish what I want? If not, could it be possible in future versions of the language? (I'm thinking that maybe one day we will have named type arguments, or that we only need to explicitly supply type arguments that can't be inferred?) Or am I just being silly?

  • Mapping enum with fluent nhibernate

    - by Puneet
    I am following the http://wiki.fluentnhibernate.org/Getting%5Fstarted tutorial to create my first NHibernate project with Fluent NHibernate I have 2 tables 1) Account with fields Id AccountHolderName AccountTypeId 2) AccountType with fields Id AccountTypeName Right now the account types can be Savings or Current So the table AccountTypes stores 2 rows 1 - Savings 2 - Current For AccoutType table I have defined enum public enum AccountType { Savings=1, Current=2 } For Account table I define the entity class public class Account { public virtual int Id {get; private set;} public virtual string AccountHolderName {get; set;} public virtual string AccountType {get; set;} } The fluent nhibernate mappings are: public AgencyMap() { Id(o => o.Id); Map(o => o.AccountHolderName); Map(o => o.AccountType); } When I try to run the solution, it gives an exception - InnerException = {"(XmlDocument)(2,4): XML validation error: The element 'class' in namespace 'urn:nhibernate-mapping-2.2' has incomplete content. List of possible elements expected: 'meta, subselect, cache, synchronize, comment, tuplizer, id, composite-id' in namespace 'ur... I guess that is because I have not speciofied any mapping for AccountType. The questions are: How can I use AccountType enum instead of a AccountType class? Maybe I am going on wrong track. Is there a better way to do this? Thanks!

  • Sharing common class in wcf project

    - by Saint
    class MyCommonClass { //properties } This class should be accessible in service project wcf-client project the other for which they are references. In this common project I can't generate servicereferences. I think, I could don't generate MyCommonClass in ServiceReferences but how to mark class to be nonserializable? In properties there's IgnoreDataMemberAttribute. I tried also reuse MyCommonClass type located in common project, but it is still generated

  • Which language to learn C# or Salesforce.com/apex for C++ programmer

    - by polapts
    Being a C++ programmer with 7-8 years of experience, I wanted to know the market trends. When I searched a little bit I found more jobs with keyword C# than C++ or Java. I am just wondering if it is a good idea to learn C# or Java from a career perspective. Also, I read somewhere about Salesforce/apex. It was mentioned that this is something in vogue. So my question is which technology I should go for C#/Java/Salesforce(Apex) from career perspective? Thanks

  • C#/CopyFile: Cross-platform code with Progress

    - by Murat
    Hi everyone, Please suggest me a C# cross-platform solution to copy a File with progress. The method should be able to copy the file on Mono as well on .NET. P.S. Most of the solutions here refers to CopyFileEx (which uses PInvoked and I am not sure if this will works on a Mono) P.S.S. Many thanks in advance! -- Murat

  • Which design pattern is most appropriate?

    - by Anon
    Hello, I want to create a class that can use one of four algorithms (and the algorithm to use is only known at run-time). I was thinking that the Strategy design pattern sounds appropriate, but my problem is that each algorithm requires slightly different parameters. Would it be a bad design to use strategy, but pass in the relevant parameters into the constructor?. Here is an example (for simplicity, let's say there are only two possible algorithms) ... class Foo { private: // At run-time the correct algorithm is used, e.g. a = new Algorithm1(1); AlgorithmInterface* a; }; class AlgorithmInterface { public: virtual void DoSomething = 0; }; class Algorithm1 : public AlgorithmInterface { public: Algorithm1( int i ) : value(i) {} virtual void DoSomething(){ // Does something with int value }; int value; }; class Algorithm2 : public AlgorithmInterface { public: Algorithm2( bool b ) : value(b) {} virtual void DoSomething(){ // Do something with bool value }; bool value; };

  • How to redirect a URL with GET variables in routes.rb without Rails stripping out the variable first?

    - by Michael Hopkins
    I am building a website in Rails to replace an existing website. In routes.rb I am trying to redirect some of the old URLs to their new equivalents (some of the URL slugs are changing so a dynamic solution is not possible.) My routes.rb looks like this: match "/index.php?page=contact-us" => redirect("/contact-us") match "/index.php?page=about-us" => redirect("/about-us") match "/index.php?page=committees" => redirect("/teams") When I visit /index.php?page=contact-us I am not redirected to /contact-us. I have determined this is because Rails is removing the get variables and only trying to match /index.php. For example, If I pass /index.php?page=contact-us into the below routes I will be redirected to /foobar: match "/index.php?page=contact-us" => redirect("/contact-us") match "/index.php?page=about-us" => redirect("/about-us") match "/index.php?page=committees" => redirect("/teams") match "/index.php" => redirect("/foobar") How can I keep the GET variables in the string and redirect the old URLs the way I'd like? Does Rails have an intended mechanism for this?

  • Can anyone tell me what's wrong in this part of code

    - by Mobin
    string name = ((DateTimePicker)sender).Name.ToString(); name = name.Substring(0, name.Length - 1); name = name + "4"; TimeSpan duration = new TimeSpan(); duration = ((DateTimePicker)sender).Value - ((DateTimePicker)panel2.Controls[name]).Value; name = name.Substring(0, name.Length - 1); name = name + "6"; ((MaskedTextBox)panel2.Controls[name]).Text = duration.ToString(); On execution it gives me Object reference not set to instance of an object similar functionality is used on other places but I can't find out what I have to reinitialize here :$ The casting for datetimepicker is fine I have to get a name for the datetiempicker to identify the row it's on in my form and the picker before that to calculate their differences and then print that difference in a maskedtext box from the control whose name I make using names of two datetimepickers but when I access controls in the error line I get this message.

  • Cheap windows driver signing for 64 bit Windows 7

    - by kayahr
    I need to install the libusb-win32 driver on Windows 7 64 bit machines. This driver is open source so it is not digitally signed so I want to do this my self but I wonder if this can be done WITHOUT paying lot of money. Is it possible to use a certificate which is NOT signed by Verisign or GlobalSign? Maybe self-signed or by using StartSSL instead? And if yes, how do I do it? According to this howto I have to use a "cross-certificate" (And there are only six available on the Microsoft list and most of them are for CAs which are no longer active) I don't care if the user is confronted with a warning message. I can even accept if the user has to install a special CA certificate first. I only require that the driver runs without manually disabling the signature check on each windows startup.

  • Very strange client/browser issue

    - by Jeriko
    One of our clients has logged a very strange issue with us- We launched a preview for their website, but when it's viewed on their main PC, peculiar things start to happen... At first, the stylesheet wasn't being found, and so accessing any page resulted in one void of all styles. We sent them a direct link to the stylesheet, which was viewable from all our computers in the office - but gave a "File Not Found" error on their side. I then deleted the file, and replaced it with a new blank file, which he could then access. Copy-pasted screen.css contents into this file, and he could then view it fine, and stylesheets magically worked on the site again. Now, he can view styles, but not the referenced header images. The strange thing is that this problem doesn't exist on any other PC we've tested, or on any other site on the problem computer, but obviously we'd like our client's site to work for them. The strange thing is, they can view other sites of ours, hosted on the same server, built on top of the same CMS (and so most of the files are the same) without problem - but are getting 404s for files that most definitely do exist. Stylesheets are not turned off, nor is anything specifically deactivated on their browser (as other sites are fine) Reloading with CTRL+F5 doesn't help The client is using the latest version of firefox Any ideas here on what to try / how to narrow the problem down?

  • Can't see how to compile a header file with /clr switch in a mixed class

    - by MattN
    When creating a mixed mode class, on compilation the header file complains that it needs to be complied with the /clr switch as it is a mixed mode class, however, I can't see any option to specifically compile that header with /clr from visual studio, and I don't want to set the entire project with a /clr flag, Does anyone know how I can specify that this header file is compiled correctly with /clr? Thanks in advance!

  • In what package should a "Settings" class be?

    - by Tom
    I've in the middle of building an application but found myself too easily creating new packages without keeping the project's structure in mind. Now, I'm trying to redo the whole project structure on paper first. I am using a Settings class with public properties, accessed as settings for several other classes around the project. Now, since this Settings class applies for the whole project, I am unsure if it should be packaged and if so, in what kind of package should it exist? Or should it be in the root (the default package) with the main application class? I've been thinking about putting it in my utils package, then again I don't think it really is an utlity. Any strategies on how to decide on such package structure for example for a Settings class?
