  • Licensing WPF application

    - by Macros
    Does anyone have any guidance on the best way to manage licensing for a WPF application? I would like to have different levels of licensing (Free, Trial and Professional). The app itself will probably be distributed with a WiX installer (if that makes any difference)

  • Why sockets does not die when server dies? Why socket dies when server is alive?

    - by Roman
    I try to play with sockets a bit. For that I wrote very simple "client" and "server" applications. Client: import java.net.*; public class client { public static void main(String[] args) throws Exception { InetAddress localhost = InetAddress.getLocalHost(); System.out.println("before"); Socket clientSideSocket = null; try { clientSideSocket = new Socket(localhost,12345,localhost,54321); } catch (ConnectException e) { System.out.println("Connection Refused"); } System.out.println("after"); if (clientSideSocket != null) { clientSideSocket.close(); } } } Server: import java.net.*; public class server { public static void main(String[] args) throws Exception { ServerSocket listener = new ServerSocket(12345); while (true) { Socket serverSideSocket = listener.accept(); System.out.println("A client-request is accepted."); } } } And I found a behavior that I cannot explain: I start a server, than I start a client. Connection is successfully established (client stops running and server is running). Then I close the server and start it again in a second. After that I start a client and it writes "Connection Refused". It seems to me that the server "remember" the old connection and does not want to open the second connection twice. But I do not understand how it is possible. Because I killed the previous server and started a new one! I do not start the server immediately after the previous one was killed (I wait like 20 seconds). In this case the server "forget" the socket from the previous server and accepts the request from the client. I start the server and then I start the client. Connection is established (server writes: "A client-request is accepted"). Then I wait a minute and start the client again. And server (which was running the whole time) accept the request again! Why? The server should not accept the request from the same client-IP and client-port but it does!

    When compiling this code: public class WindsorControllerFactory : IControllerFactory { private readonly WindsorContainer _container; public WindsorControllerFactory(WindsorContainer container) { _container = container; } public IController CreateController(RequestContext requestContext, string controllerName) { return (IController)_container.Resolve(controllerName); } public void ReleaseController(IController controller) { _container.Release(controller); } } I am getting this error: 'WindsorControllerFactory' does not implement interface member 'System.Web.Mvc.IControllerFactory.CreateController(System.Web.Routing.RequestContext, string)' Well, it obviously implements this member. Has anyone encountered this problem?

    - by Ken
    All, I'm working on a Real-time system, VxWorks I think, I'm saving application settings to a file. What's the best way to handle preserving the settings if the system shuts down or loses power in the middle of a file write?

    - by Tony_Henrich
    I have a third party tool that creates an img tag through code using HtmlTextWriter's RenderBeginTag, RenderEndTag & AddAttribute methods. I want to get the resulting HTML into a string.

The InnerWriter type of the HtmlTextWriter is of type HttpWriter. Any ideas on how to copy the output html into a string?

  • asp.net mvc 2 method not found

    - by Debra
    When I run my asp.net mvc 2 site (shared hosting) I get the following error: Method not found: 'Void System.Web.Mvc.DataAnnotationsModelValidatorProvider.set_AddImplicitRequiredAttributeForValueTypes(Boolean)'. In the bin directory I have System.Web.Mvc.dll version 2.0.50217.0 On my local dev machine it runs fine. Is it possible that if the hosting provider has a different mvc 2 version installed it would cause this error? Thank you!

  • How to get Win32 to use Windows XP style fonts

    - by Semen Semenych
    I'm writing a Win32 application using plain C and WinAPI. No MFC or C++ is allowed. To get the controls to draw using the appropriate style, I use a manifest, as described in the corresponding MSDN article. Everything is fine, and when I change the system style, my application changes style as well. But the font used is just ugly. How do I force the application to use the standard system font?

  • If you could take one computer science course now, what would it be?

    - by HenryR
    If you had the opportunity to take one computer science course now, and as a result significantly increase your knowledge in a subject area, what would it be? Undergraduate or graduate level. Compilers? Distributed algorithms? Concurrency theory? Advanced operating systems? Let me know why. (Note that I appreciate this isn't a far fetched scenario - but time and inertia might be preventing people from taking the course or reading the book or whatever)

I have no problem issuing the PUT CONTAINER and INVOKE SERVICE api commands, but when I issue GET CONTAINER I am not receiving any containers or data. No response codes or error messages, but no data. Any ideas on how to debug this would be greatly appreciated. Thanks,

  • Import? Initialize? what do to?

    - by Jeremy B
    I'm working on homework and I'm close but I am having an issue. I just learned how to work with packages in eclipse so I have a class that is importing another class from a package (I think I said that right) The main prompts the user to enter an integer between -100 and 100 and I am having an issue with validating it. I know the issue is where I'm importing I'm just unsure the direction I need to go to fix it. This is a section of my main code. (my issue starts with the last couple lines if you want to skip ahead) import myUtils.util.Console; public class ConsoleTestApp { public static void main(String args[]) { // create the Console object Console c = new Console(); // display a welcome message c.println("Welcome to the Console Tester application"); c.println(); // int c.println("Int Test"); int i = c.getIntWithinRange("Enter an integer between -100 and 100: ", -101, 101); c.println(); I have a class called Console that is located in another package that I believe I have properly imported. here is the code I am stuck on in my console class. public int getIntWithinRange(String prompt, int min, int max) { int i = 0; boolean isValid = false; while (isValid == false) { System.out.println(prompt); if (sc.hasNextInt()) { //if user chooses menu option less than 1 the program will print an error message i = sc.nextInt(); if (i < min) { System.out.println("Error! Please enter an int greater than -100"); } else if (i > max) { System.out.println("Error! Please enter an int less than 100"); } else isValid = true; } else System.out.println("Error! Invalid number value"); sc.nextLine(); } // return the int return i; } when I run this I keep getting my last print which is an invalid number value. am I not importing the code from the main method in the other console properly?

  • Is there an easy method to combine two relative paths in C# ?

    - by Ioannis
    I want to combine two relative paths in C#. For example: string path1 = "/System/Configuration/Panels/Alpha"; string path2 = "Panels/Alpha/Data"; I want to return string result = "/System/Configuration/Panels/Alpha/Data"; I can implement this by splitting the second array and compare it in a for loop but I was wondering if there is something similar to Path.Combine available or if this can be accomplished with regular expressions or Linq? Thanks

  • Discover NullPointerException bugs using FindBug

    When I run FindBug on this code, it reports NO issues. boolean _closed = false; public void m1(@Nullable String text) { if(_closed) return; System.out.println(text.toLowerCase()); } While here it finds issue as expected: public void m1(@Nullable String text) { System.out.println(text.toLowerCase()); // FireBug: text must be nonnull but is marked as nullable } Why does it fail in first case?

  • How to speed up/slow down application's 'time'

    - by overboming
    I guess I am not saying it right in the title. What I intend to do is to hook to some system api,like a time interrupt happens every amount of time (which is how every application in the operating system interprets time) and make an application's call to this api return some bigger/smaller result. So from the point view of an applicaiton, time has been speed up or slow down. I have found some application on windows doing this, can anyone gives me some pointers on how to implement this on Mac OS X?
