  • MembershipProvider, IPrincipal, IIdentity?

    - by MRFerocius
    Hello guys; I have a conceptual question... I am making an Intranet application (Web platform) for a company. I have a SQL Server DB with these tables: Users (userID, userName, userPass, roleID) Roles (roleID, roleName) Pages (pageID, pageURL) RolesXPages(pageID, roleID) How is the best way to create a structure to store all this information while the user navigates the site, I mean, on the thread I should be able to check his role, his pages (the ones he can access) I have been reading and there is a lot of stuff there where Im confused, I saw the MembershipProvider, IPrincipal, IIdentity, etc classes but Im not sure what should be the best one for me. Any thoughts... Thanks in advance! Edit: Everytime gets more confusing... I just want to handle those structures at runtime and be able to mantain state during page callbacks or changing pages...

  • Best practices for organizing .NET P/Invoke code to Win32 APIs

    - by Paul Sasik
    I am refactoring a large and complicated code base in .NET that makes heavy use of P/Invoke to Win32 APIs. The structure of the project is not the greatest and I am finding DllImport statements all over the place, very often duplicated for the same function, and also declared in a variety of ways: The import directives and methods are sometimes declared as public, sometimes private, sometimes as static and sometimes as instance methods. My worry is that refactoring may have unintended consequences but this might be unavoidable. Are there documented best practices I can follow that can help me out? My instict is to organize a static/shared Win32 P/Invoke API class that lists all of these methods and associated constants in one file... (The code base is made up of over 20 projects with a lot of windows message passing and cross-thread calls. It's also a VB.NET project upgraded from VB6 if that makes a difference.)

  • Adding Columns to JTable dynamically

    - by martilyo
    I have an empty JTable, absolutely nothing in it. I need to dynamically generate its table columns in a certain way. A simplified version for the code I have for my attempt: @Action public void AddCol() { for (int i = 0; i < 10; i++) { TableColumn c = new TableColumn(i); c.setHeaderValue(getColNam(i)); table.getColumnModel().addColumn(c); } } But I'm getting an Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: 0 >= 0 error. What am I doing wrong?

  • noClassDefFoundError using Scala Plugin for Eclipse

    - by Jacob Lyles
    I successfully implemented and ran several Scala tutorials in Eclipse using the Scala plugin. Then suddenly I tried to compile and run an example, and this error came up: Exception in thread "main" java.lang.NoClassDefFoundError: hello/HelloWorld Caused by: java.lang.ClassNotFoundException: hello.HelloWorld at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:315) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:330) at java.lang.ClassLoader.loadClass(ClassLoader.java:250) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:398) After this point I could no longer run any Scala programs in Eclipse. I tried cleaning and rebuilding my project, closing and reopening my project, and closing and reopening Eclipse.

  • Scheduling Swingworker threads

    - by Simonw
    Hi, I have a 2 processes to perform in my swing application, one to fill a list, and one to do operations on each element on the list. I've just moved the 2 processes into Swingworker threads to stop the GUI locking up while the tasks are performed, and because I will need to do this set of operations to several lists, so concurrency wouldn't be a bad idea in the first place. However, when I just ran fillList.execute();doStuffToList.execute(); the doStuffToList thread to ran on the empty list (duh...). How do I tell the second process to wait until the first one is done? I suppose I could just nest the second process at the end of the first one, but i dunno, it seems like bad practice.

  • MkMapView setRegion animation prevents touch events on Annotation Views

    - by Vlad Gurovich
    Hi there! We have a MKmapView with a bunch of Image Annotation where each Image annotation responds to touch by overriding these methods of AnnotationView subclass: -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event; -(void) touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event Our map region is updated using [MkMapView setRegion:animated:] whenever the new location is received and is far enough from the old location to make a difference. What I noticed is that if we set animated flag to YES the touches on our annotation are rarely detected(probably due to the fact that main thread is busy animating between two map regions. When we set animated flag to NO, everything is fine, but map transition may(or may not) become jerky. The question I have is whether this is an expected behavior of animated flag of [MkMapView setRegion:animated] function or whether there is a workaround for this issue. Thanks in advance

  • C# Improvement on a Fire-and-Forget

    - by adam
    Greetings I have a program that creates multiples instances of a class, runs the same long-running Update method on all instances and waits for completion. I'm following Kev's approach from this question of adding the Update to ThreadPool.QueueUserWorkItem. In the main prog., I'm sleeping for a few minutes and checking a Boolean in the last child to see if done while(!child[child.Length-1].isFinished){ Thread.Sleep(...); } This solution is working the way I want, but is there a better way to do this? Both for the independent instances and checking if all work is done. Thanks

  • errors deploying an EAR with EJBs 2.1 into JBoss AS5

    - by Marina
    Hi, I'm porting an application with EJBs 2.1 from Weblogic9 to JBoss AS5. I have made some of the changes like adding jboss.xml descriptors to EJBs and fixing application.xml of the EAR, but there are still problems when deploying the EAR. Here is a summary of the the latest error I'm getting when the first EJB is being deployed by JBoss (I will add the full stack trace at the end of the message): 14:15:48,124 ERROR [AbstractKernelController] Error installing to Parse: name=vf sfile:/C:/Marina/Tools/jboss-5.1.0.GA/server/default/deploy/contracts.ear/ state =Not Installed mode=Manual requiredState=Parse org.jboss.deployers.spi.DeploymentException: Error creating managed object for v fsfile:/C:/Marina/Tools/jboss-5.1.0.GA/server/default/deploy/contracts.ear/admin -ejb.jar/ ....

  • Perl: Event-driven Programming

    - by Shiftbit
    Is there any POSIX signals that I could utilize in my perl program to create event-driven programming? Currently I have multi-process program that is able to cross communicate but my parent thread is only able to listen to listen at one child at a time. foreach (@threads) { sysread(${$_}{'read'}, my $line, 100); chomp($line); print "Parent hears: $line\n"; } The problem is that the parent sits in a continual wait state until it receives it a signal from the first child before it can continue on. I am relying on 'pipe' for my intercommunication. My current solution is very similar to: http://stackoverflow.com/questions/2558098/how-can-i-use-pipe-to-facilitate-interprocess-communication-in-perl If possible I would like to rely on a $SIG{...} event or any non-CPAN solution.

  • How to tell if a datareader is open on a connection and close it

    - by Earlz
    Hi, I'm setting up a little thing for connection pooling and on of the more common bugs that we have occur(its always an easy fix, but we just can't remember reader.Close()!) it is when we have a connection that is used by a lot of classes/methods and one method opens a data reader and forgets to close it. This isn't really bad cause a lot of times all you have to do is go into the debugger and go up one level and see the function before it was and check if it had an unclosed data reader. Now, here is the bigger problem. In this connection pool, if a datareader is open, then it's not known until a thread gets a connection and tries to use it and the thing that originally opened the data reader may no longer even be alive. So quite simply, how can you detect if a data reader is open on a connection and is there a way to close the reader without closing the connection?

  • Not able to access UNC share after doing the Imperosnation

    - by Nitin Jain
    We have to access a network UNC share which is say allowing access to USER1. Our exe is running with LOCAL SYSTEM account. In the exe, we do Impersonation with "USER1" credentials so that exe can access UNC share. But after doing the impersonation, we are still getting error "Access denied" while accessing that UNC share. After the impersonation, we are enabling following privileges on the Impersonated thread: SE_BACKUP_NAME SE_CHANGE_NOTIFY_NAME SE_CREATE_GLOBAL_NAME SE_DEBUG_NAME SE_IMPERSONATE_NAME SE_RESTORE_NAME SE_SECURITY_NAME SE_TAKE_OWNERSHIP_NAME SE_TCB_NAME Do we need to enable any other privileges or we are missing something else? Thanks -- Nitin

  • Best practices for large solutions in Visual Studio (2008)

    - by Eyvind
    We have a solution with around 100+ projects, most of them C#. Naturally, it takes a long time to both open and build, so I am looking for best practices for such beasts. Along the lines of questions I am hoping to get answers to, are: how do you best handle references between projects should "copy local" be on or off? should every project build to its own folder, or should they all build to the same output folder(they are all part of the same application) are solutions folders a good way of organizing stuff? I know that splitting the solution up into multiple smaller solutions is an option, but that comes with its own set of refactoring and building headaches, so perhaps we can save that for a separate thread :-)

  • How do i judge when the NetWorkStream finishes by using .net TcpClient to communicate

  • Programatically detect number of physical processors/cores or if hyper-threading is active on Window

    - by HTASSCPP
    I have a multithreaded c++ application that runs on Windows, Mac and a few Linux flavours. To make a long story short: Inorder for it to run at maximum efficiency I have to be able to instantiate a single thread per physical processor/core. Creating more threads than there are physical processors/cores degrades the performance of my program considerably. I can already correctly detect the number of logical processors/cores correctly on all three of these platforms. To be able to detect the number of physical processors/cores correctly I'll have to detect if hyper-treading is supported AND active. My question therefore is if there is a way to detect whether hyperthreading is supported AND ENABLED? If so, how exactly.

  • Conditional restart on Activity onConfigurationChanged

    - by yuku
    I want to make an activity that allows orientation changes on some condition, but not otherwise. More exactly I want to prevent restarting the activity when a background thread is busy. I have put the configChanges attribute on the activity manifest, and onConfigurationChanged is called when the orientation changes. However I want to allow the app to change the orientation when allowed. @Override public void onConfigurationChanged(Configuration newConfig) { super.onConfigurationChanged(newConfig); if (orientationChangeAllowed) { // how to I restart this activity? } else { // don't do anything } }

  • How to set WCF threads to schedual differently

    - by Gilad
    Hi, I'm running a winservice that has 2 main objectives. Execute/Handle exposed webmethods. Run Inner processes that consume allot of CPU. The problem is that when I execute many inner processes |(as tasks) that are queued to the threadpool or taskpool, the execution of the webmethods takes much more time as WCF also queues its executions to the same threadpool. This even happens when setting the inner processes task priority to lowest and setting the webmethods thread priority to heights. I hoped that Framework 4.0 would improve this, and they have, but still it takes quite allot of time for the system to handle the WCF queued tasks if the CPU is handling other inner tasks. Is it possible to change the Threadpool that WCF uses to a different one? Is it possible to manually change the task queue (global task queue, local task queue). Is it possible to manually handle 2 task queues that behave differently ? Any help in the subject would be appropriated. Gilad.

  • OBJ-C: Call an instance of core-plot graph from separate view controller

    - by Kevin
    I'm using a view controller i.e. ViewController:UIViewController and have another class GraphViewController:UIViewController . How do I call an instance of GraphViewController and place it into my ViewController? I am currently trying to call the plot within my ViewController directly, but I want to make the graph modular so I don't have to copy code if I use the same graph again. ViewController has methods -(void) refreshGraph; //Inhereted Methods -(NSUInteger)numberOfRecordsForPlot:(CPPlot *)plot; -(NSNumber *)numberForPlot:(CPPlot *)plot field:(NSUInteger)fieldEnum recordIndex:(NSUInteger)index; How do I move these methods to a separate class and then call it to get the same plot in my ViewController? I am sure there must be a thread on this somewhere but I can't seem to find it.

  • Removing Divider Line from UISplitViewController

    - by tilomitra
    Guys, I know a similar question exists but the thread seems to be inactive, and I really would like this question to be answered. It's been annoying me for a few days now. I'm wondering how to remove the divider line between the Master and Detail view in the UISplitViewController. I know its possible to remove/hide/cover it up because I see some apps in the store without that line. I have tried setting backgroundColor to clearColour on my views but to no avail. So SO community, you're my only hope!

  • C# threading pattern that will let me flush

    - by Jeff Alexander
    I have a class that implements the Begin/End Invocation pattern where I initially used ThreadPool.QueueUserWorkItem() to do thread my work. I now have the side effect where someone using my class is calling the Begin (with callback) a ton of times to do a lot of processing so ThreadPool.QueueUserWorkItem is creating a ton of threads to do the processing. That in itself isn't bad but there are instances where they want to abandon the processing and start a new process but they are forced to wait for their first request to finish. Since ThreadPool.QueueUseWorkItem() doesn't allow me to cancel the threads I am trying to come up with a better way to queue up the work and maybe use an explicit FlushQueue() method in my class to allow the caller to abandon work in my queue. Anyone have any suggestion on a threading pattern that fits my needs?

  • form update too expensive to be executed in Winform.Timer.Tick

    - by Abruzzo Forte e Gentile
    Hi all I have a WinForm drawing a chart from available data. I programmed it so that every 1 secong the Winform.Timer.Tick event calls a function that: will dequeue all data available will add new points on the chart Right now data to be plotted is really huge and it takes a lot of time to be executed so to update my form. Also Winform.Timer.Tick relies on WM_TIMER , so it executes in the same thread of the Form. Theses 2 things are making my form very UNresponsive. What can I do to solve this issue? I thought the following: moving away from usage of Winform.Timer and start using a System.Threading.Timer use the IsInvokeRequired pattern so I will rely on the .NET ThreadPool. Since I have lots of data, is this a good idea? I have fear that at some point also the ThreadPool will be too long or too big. Can you give me your suggestion about my issue? Thank you very much! AFG

  • How does the timeout work in Restlet's client class?

    - by Greg Noe
    Here's some code: Client client = new Client(Protocol.HTTP); client.setConnectTimeout(1); //milliseconds Response response = client.post(url, paramRepresentation); System.out.println("timed out"); What I would expect to happen is that it prints "timed out" before the resource has time to process. Instead, nothing happens with the timeout and it doesn't print "timed out" until after the resource returns. Even if I put a Thread.sleep(5000) at the resource that's handling the request, the entire sleep is performed, like the timeout did nothing. Anyone have experience with this? I'm using Restlet 1.1.1. Thanks.
