  • Class architecture, no friends allowed

    - by Captain Comic
    The question of why there are no friends in C# has been extensively discussed. I have the following design problems. I have a class that has only one public function AddOrder(Order ord). Clients are allowed to call only this function. All other logic must be hidden. Order class is listening to market events and must call other other function of TradingSystem ExecuteOrder, so I have to make it public as well. Doing that I will allow clients of Trading system to call this function and I don't want that. class TradingSystem { // Trading system stores list of orders List<Order> _orders; // this function is made public so that Order can call ir public ExecuteOrder(Order ord) { } // this function is made public for external clients public AddOrder(OrderRequest ordreq) { // create order and pass it this order.OnOrderAdded(this); } } class Order { TradingSystem _ts; public void OnOrderAdded(TradingSystem ts) { _ts = ts; } void OnMarketEvent() { _ts.ExecuteOrder() } }

  • What scripting language would you use to put text over a generated image ?

    - by Younes
    I got this question from my cousin: "What will be the best way to create a similar working website just like: http://www.plakletters.nl". I have looked into the website and think that to start of with i'm gonna help my cousin write a script that loads all fonts installed on the system into a dropdownlist. This dropdownlist will post a font value back to the page and will create images with the input of a user that comes from a textbox. This images will have to be created server side, and I also want to give the users the ability (in the future) to lay their own text over an uploaded image, to see what the result will look like on their own image. I found some information about how to create images using php, I don't know if php can output a list of installed fonts from the system it's running on. What scripting language would you use to get this job done? Keep in mind i would just like to start with outputting some images based on user input using a scripting language.

  • In .NET, How to obtain the target of a symbolic link (or Reparse Point)?

    - by Cheeso
    In .NET, I think I can determine if a file is a symbolic link by calling System.IO.File.GetAttributes(), and checking for the ReparsePoint bit. like so: var a = System.IO.File.GetAttributes(fileName); if ((a & FileAttributes.ReparsePoint) != 0) { // it's a symlink } How can I obtain the target of the symbolic link, in this case? ps: I know how to create a symbolic link. It requires P/Invoke: [Interop.DllImport("kernel32.dll", EntryPoint="CreateSymbolicLinkW", CharSet=Interop.CharSet.Unicode)] public static extern int CreateSymbolicLink(string lpSymlinkFileName, string lpTargetFileName, int dwFlags);

  • Do programmable Ethernet devices (think onboard CPU) really exist?

    - by PeterM
    I've heard from various people that programmable Ethernet cards exist and are easily available. However I have yet to be able to track down one of these mythical devices so I'm wondering if they're just that - a myth. Such a programmable card has a gigabit Ethernet interface, has a programmable CPU and connects to the host system via PCI Express. The problem area these cards address are low latency network applications where the card itself does the work and "reports back" to the operating system. Basically the card acts as a co-processor and handles all the low latency requirements on the card, thus avoiding the issues of writing low latency code in user-land - think 0.4ms - 0.5ms response times. So my question is, do these cards really exist and if so, where can I get my hands on one?

  • NGINX + PHP-FPM - Strange issue when trying to display images via php-gd / readfile - Connection wont terminate

    - by anonymous-one
    Ok, to get the details out of the way: The php script can be anything as simple as: <? header('Content-Type: image/jpeg'); readfile('/local/image.jpg'); ?> When I try to execute this via nginx + php-fpm what happens is the image shows up in the browser, here is what happens: IE - The page stays blank for a long period of time, and eventually the image is shown. Chrome - The image shows, but the loading spinner spins and spins for a long period of time. Eventually the debugger will show the image in red as in error, but the image shows up fine. Everything else on the server works great. Its pushing out about 100mbit steady serving static content. So this is definatly a php-fpm related issue. I THINK this may have something to do with the chunked encoding being sent back wrong? Also, I threw in a pause before the image was read, and got the pid of the fpm process, and it looks as tho its terminatly correctly (from strace): shutdown(3, 1 /* send */) = 0 recvfrom(3, "\1\5\0\1\0\0\0\0", 8, 0, NULL, NULL) = 8 recvfrom(3, "", 8, 0, NULL, NULL) = 0 close(3) = 0 The above was dumped long before ie/chrome decided to give up (even tho the image was shown) loading the image. Displaying HTML / text content is fine. Big bodies etc all load nice and fast and terminate right away (as they should). Doing something like: THIS IS THE IMAGE ---BINARY DUMP OF IMAGE--- Works fine too. Any ideas?

  • C#, cannot understand this error?

    - by 5YrsLaterDBA
    I am using VS2008. I have a project, SystemSoftware project, connect with a database and we are using L2E. I have a RuntimeInfo class which contains some shared information there. It looks like this: public class RuntimeInfo { public const int PWD_ExpireDays = 30; private static RuntimeInfo thisObj = new RuntimeInfo(); public static string AndeDBConnStr = ConfigurationManager.ConnectionStrings["AndeDBEntities"].ConnectionString; private RuntimeInfo() { } /// <summary> /// /// </summary> /// <returns>Return this singleton object</returns> public static RuntimeInfo getRuntimeInfo() { return thisObj; } } Now I added a helper project, AndeDataViewer, to the solution which creates a simple UI to display data from the database for testing/verification purpose. I don't want to create another set of Entity Data Model in the helper project. I just added all related files as a link in the new helper project. In the AndeDataViewer project, I get the connection string from above RuntimeInfo class which is a class from my SystemSoftware project as a linked file. The code in AndeDataViewer is like this: public class DbAccess : IDisposable { private String connStr = String.Empty; public DbAccess() { connStr = RuntimeInfo.AndeDBConnStr; } } My SystemSoftware works fine that means the RuntimeInfo class has no problem there. But when I run my AndeDataViewer, the statement inside above constructor, connStr = RuntimeInfo.AndeDBConnStr; , throws an exception. The exception is copied here: System.TypeInitializationException was unhandled Message="The type initializer for 'MyCompany.SystemSoftware.SystemInfo.RuntimeInfo' threw an exception." Source="AndeDataViewer" TypeName="MyCompany.SystemSoftware.SystemInfo.RuntimeInfo" StackTrace: at AndeDataViewer.DbAccess..ctor() in C:\workspace\SystemSoftware\Other\AndeDataViewer\AndeDataViewer\DbAccess.cs:line 17 at AndeDataViewer.Window1.rbRawData_Checked(Object sender, RoutedEventArgs e) in C:\workspace\SystemSoftware\Other\AndeDataViewer\AndeDataViewer\Window1.xaml.cs:line 69 at System.Windows.RoutedEventHandlerInfo.InvokeHandler(Object target, RoutedEventArgs routedEventArgs) ....

Source="AndeDataViewer" StackTrace: at MyCompany.SystemSoftware.SystemInfo.RuntimeInfo..cctor() in C:\workspace\SystemSoftware\SystemSoftware\src\systeminfo\RuntimeInfo.cs:line 24 InnerException: I cannot understand this because it looks fine to me but why there is an exception? we cannot access static variable when a class is a linked class? A linked class should be the same as the local class I think. "Linked" here means when I add file I use "Add As Link".

  • How i can setup a nginx cache strategy that first try amazon s3, then memcache and do a fallback on miss?

    - by Tim
    i have a large site with lot of pages that almost never change, right now i am using two memcache servers (amazon elasticache), but this its really expensive. Thats why for this files that barely never change i want to upload them to amazon s3 and shutdown 1 memcache server. Here is my conf; location ~ /longterm/(.*){ proxy_pass http://amazonS3bucket; proxy_intercept_errors on; proxy_next_upstream http_404; error_page 404 503 = @fallback_memcached } location @fallback_memcache { set $memcached_key $uri; memcached_pass name:11211; error_page 404 @fallback; } location @fallback { try_files $uri $uri/index.html } I dont know why but the config doesnt work on the final fallback; if i got an amazon S3 hit it works, if i got an amazon S3 miss and a memcache hit it works, but if i got an amazon S3 miss then a memcache miss when it try to resolve the las fallback it fails. I am also thinking in use the amazon s3 fuse http://code.google.com/p/s3fs/ instead of the proxy pass i think it would be easier for implement, i would also be less performant?

  • Storing Data as XML BLOB

    - by NBrowne
    Hi, At the moment the team i am working with is looking into the possibility of storing data which is entered by users from a series of input wizard screens as an XML blob in the database. the main reason for this being that i would like to write the input wizard as a component which can be brought into a number of systems without having to bring with it a large table structure. To try to clarify if the wizard has 100 input fields (for example) then if i go with the normal relational db structure then their will be a 1 to 1 relationship so will have 100 columns in database. So to get this working in another system will have to bring the tables,strore procedures etc into the new system. I have a number of reservations about this but i would like peoples opinions?? thanks

  • Need inputs in architecting SOA which handles multiple versions of schema

    - by user555400
    Hi, I am working on an assignment where building SOA for an existing application. I am trying to get input from you guys on which is better approach for the SOA application: Here is the requirement: We want to develop SOA application that helps other vendors to integrate with our system. I also understand for some clients we need to bring new fields to support the integration. Solution Needed: Looking for either one SOA application which can handle all the clients to do the integration with our system. Question Is it possible to do so? Because we might have different contracts possibly bringing new fields coming into the contracts. (or) Develop a another SOA service if the service contract changes and have a front gate SOA service to divert the call to the appropriate SOA services based on the version [Probably mentioned in the SOAP header]. If anyone of you guys have handled this type of requirement and know how to handle this problem, that would help me. Thanks, Nazim

  • There is more then one Point class

    - by Dmitry
    Today I hit something very annoying while working with one of my colleagues. It seems there are two Point classes in .NET and by mistake we were trying for a good few minutes to figure out why our "Point(x,y)" wouldn’t take double, but only Int. Turns out we were using the wrong one since the XAML element in question needed the version with Double. So, based on what you actually want to do, make sure you’re using the right namespace. Please see below for MSDN reference links for each namespace version of Point, hope this saves you some time. System.Windows Point (MSDN Ref - Double version) System.Dawing Point (MSDN Ref - Int version)

  • Is there a way to set the value of $? in a mock in Ruby?

    - by rleber
    I am testing some scripts that interface with system commands. Their logic depends on the return code of the system commands, i.e. the value of $?. So, as a simplified example, the script might say: def foo(command) output=`#{command}` if $?==0 'succeeded' else 'failed' end end In order to be able to test these methods properly, I would like to be able to stub out the Kernel backquote call, and set $? to an arbitrary value, to see if I get appropriate behavior from the logic in the method after the backquote call. I can't figure out a way to do this. (In case it matters, I'm testing using Test::Unit and Mocha.)

  • Response.Redirect exception

    - by Tedd Hansen
    Executing the line: Response.Redirect("Whateva.aspx", true); Results in: A first chance exception of type 'System.Threading.ThreadAbortException' occurred in mscorlib.dll An exception of type 'System.Threading.ThreadAbortException' occurred in mscorlib.dll but was not handled in user code The exception is because of the "true" part, telling it to end the current request immediately. Is this how it should be? If we consider: Exceptions are generally considered heavy, and many times the reason for ending the request early is to avoid processing the rest of the page. Exceptions show up in performance monitoring, so monitoring the solution will show a false number of exceptions. Is there an alternative way to achieve the same?

  • Can I save my app's state at close time in iPhone OS?

    - by Steve
    I have an app that functions much like an ebook. I have a bunch of textual information in various languages that is accessible through a number of drill down methods. When a user wants to get into where they were reading last, they currently have to navigate through the section and chapter menus to get back to where they were. An ideal solution for this would be to setup a bookmark system, which I am considering. But if I remember correctly, when iPhone OS 4 was announced, they seemed to make a big deal of the added ability to save the state of an app. Does that mean that someone using my reader app would be able to just exit right out, do whatever, and then when they came back in, it would be the reading screen just as they left it? I don't know much about how to setup a bookmarking system, I suppose it would be worth investigating, but I would probably want to just hold off for iPhone OS 4 if that is indeed what it will be capable of doing. Any thoughts or insights would be appreciated!!

  • Single C++/CLI method to wrap many type specific C functions

    - by T33C
    I am wrapping a C library using C++/CLI so that the C library can be used easily from C# in a C#'ish way. Some of the functions in this library are for putting a value into a container. There are no generics in C so there exists a function per type CLIB_SetBool(BOOL value), CLIB_SetInt(int value), CLIB_SetString(char* string) and so on. To make it easier to use from C#, I have created a single Set function which takes a System::Object. I have two related questions: With my method how would you use a switch statement on the type of System::Object to call the correct CLIB_Setxxxx function. [typeid is only for unmanaged code and I can't seem to use GetType.] Is there a better way to wrap these functions like using a Generic? [I started using template specialisation but then realised that C# doesn't see templates.] Thanks.

  • The case of the mysterious MySQL caching across restarts

    - by shanusmagnus
    I found a very slow MySQL query in my web app. The weird thing is that the query is only slow the first time it's executed, despite the fact that the query_cache is set to its default (query_cache_size 0) like so: mysql> show variables like 'query%'; +------------------------------+---------+ | Variable_name | Value | +------------------------------+---------+ | query_alloc_block_size | 8192 | | query_cache_limit | 1048576 | | query_cache_min_res_unit | 4096 | | query_cache_size | 0 | | query_cache_type | ON | | query_cache_wlock_invalidate | OFF | | query_prealloc_size | 8192 | +------------------------------+---------+ The even weirder thing is that this speedup persists even after the MySQL server has been stopped and restarted (I'm using OSX, and perform this restart using the system preferences pane.) The only way I can re-create the poor performance of the initial query is by rebooting the system. So my question is: how is this happening? Obviously some sort of caching at work, but where? And how does it persist across database restarts? This query is mediated through our web app, which comes via PHP/Apache, but there are no extra bells and whistles, and the curious caching also persists across Apache restarts. Help?

  • Convert an interface's event from VB.Net to C#

    - by Jules
    Hi, I'm struggling to convert the below code to C#. Class Class1 Implements IMyInterface Public Event MyEvent(ByVal sender As Object, ByVal e As MyEventArgs) Implements IMyInterface.MyEvent Public Sub New() AddHandler Me.Slider.ValueChanged, AddressOf OnSliderValueChanged End Sub Private Sub OnSliderValueChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) RaiseEvent MyEvent(Me, New MyEventArgs()) End Sub End Class Here's what visual studio inserts when I ask it to implement for me: event EventHandler<MyEventArgs> IMyInterface.MyEvent { add { throw new NotImplementedException(); } remove { throw new NotImplementedException(); } } With a bit of googling I'm sure I can find out what to replace the NotImplementedException parts with but VS is still telling me that the definition is not implemented anyway.
