  • Get selected items from explorer using C# .NET 3.5

    - by ghawkes
    I am writing a .NET 3.5 WPF application in C#. This application needs to be able to get the selected items out of Windows explorer when it is in the foreground. I already have the code working that handles a global Windows hotkey and then checks to see if the foreground IntPtr is from explorer. If so, I am able to obtain the System.Diagnostics.Process object that maps to explorer. At this point, I would like to obtain the list of selected items from explorer. Perhaps there is a Windows API function that I could pinvoke to do this? Thank you, G

  • In C# is there a thread scheduler for long running threads?

    - by LogicMagic
    Hi, Our scenario is a network scanner. It connects to a set of hosts and scans them in parallel for a while using low priority background threads. I want to be able to schedule lots of work but only have any given say ten or whatever number of hosts scanned in parallel. Even if I create my own threads, the many callbacks and other asynchronous goodness uses the ThreadPool and I end up running out of resources. I should look at MonoTorrent... If I use THE ThreadPool, can I limit my application to some number that will leave enough for the rest of the application to Run smoothly? Is there a threadpool that I can initialize to n long lived threads?

  • Would popup blockers stop a URL which pops up only when the user clicked on something?

    - by tomeaton
    I'm currently building a web application that can can track a users actions on a particular website and pop a URL if the user takes certain actions, such as: first click, responding to a question by clicking yes / no, clicking a submit button, or exiting the site. It is important that these URLs are served to the user and are not blocked by pop-up blockers. It is my understanding that there are certain exceptions within the major internet browsers that allow pop-ups if they are served based on some user action, rather than serving an unsolicited pop? Is this true? How do I design this web application so that it can serve these pops (and not have them blocked).

  • Secure Webservice?

    - by cam
    I'm trying to create a secure webservice (that provides simple database data) with PHP that can be connected to through my Silverlight application. I don't know enough about PHP to be able to see another way to do this. The webservice should only be accessible through the client, and only with the proper username/password. The only two ways I can imagine to do this would be by passing the username/password hash via URL, or use a "hidden form" and do it via POST_. I'm just trying to get past this point, I'm the sole developer on this project and I'm just trying to get past this PHP webservice part so I can get back to being an application programmer :) Normally, I would learn PHP, but I'm on the clock, so I'm just looking for a point in the right direction on how to achieve this!

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

    - by Tom
    I'm 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?

  • Methods in Customized View did not get invoke in AppDelegate, Why?

    - by NorthKyut
    I want the methods pauseGame in customized UIView - MyGameView get invoked when the phone is locked or interrupted. So I have a pauseGame method but it can't stop the timer when user lock screen (command+L). The lock screen did appear but the game still running at the background. So I added the testPause method to MyGameView and MyGameAppDelegate and and put a breakpoint to debug it. When screen locked it, the screen lock appeared and the code did stop at the breakpoint. But when I tried to step into the testPause method, it didn't take me to the method in MyGameView (it just passed it, not skipped) and no message was printed on terminal by NSLog. Why? What did I miss? // // MyGameAppDelegate.h // MyGame // #import <UIKit/UIKit.h> @class MyGameViewController; @class MyGameView; @interface MyGameAppDelegate : NSObject { UIWindow *window; MyGameViewController *viewController; MyGameView *view; } @property (nonatomic, retain) IBOutlet UIWindow *window; @property (nonatomic, retain) IBOutlet MyGameViewController *viewController; @property (nonatomic, retain) IBOutlet MyGameView *view; @end // // MyGameAppDelegate.m // MyGame // #import "MyGameAppDelegate.h" #import "MyGameViewController.h" #import "MyGameView.h" @implementation MyGameAppDelegate @synthesize window; @synthesize viewController; @synthesize view; - (void)applicationWillResignActive:(UIApplication *)application { /* Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state. Use this method to pause ongoing tasks, disable timers, and throttle down OpenGL ES frame rates. Games should use this method to pause the game. */ [view pauseGame]; [view testPause]; } @end // // MyGameView.h // MyGame @interface MyGameView : UIView { - (void)pauseGame; - (void)testPause; @end // // MyGameView.m // MyGame // #import "MyGameView.h" #import "AtlasSprite.h" #import "MyGameViewController.h" #import "SecondViewController.h" @implementation MyGameView - (void)pauseGame { [theTimer invalidate]; theTimer = nil; } - (void)testPause{ NSLog(@"TestPause"); } @end

  • Controller should not have domain logic. How faithful should one adhere to this tenet?

    - by Hao
    Quoting from page 49 of Pro ASP.NET MVC book It is certainly possible to put domain logic into a controller, even though you shouldn’t, just because it seems like it will work anyway. It’s easy to avoid this if you imagine that you have multiple UI technologies (e.g., an ASP.NET MVC application plus a native iPhone application) operating on the same underlying business domain layer (and maybe one day you will!). With this in mind, it’s clear that you don’t want to put domain logic into any of the UI layers. Why he seems to contradict himself on page 172? [HttpPost] public ActionResult CheckOut(Cart cart, ShippingDetails shippingDetails) { // Empty carts can't be checked out if (cart.Lines.Count == 0) ModelState.AddModelError("Cart", "Sorry, your cart is empty!"); if (ModelState.IsValid) { orderSubmitter.SubmitOrder(cart, shippingDetails); cart.Clear(); return View("Completed"); } else // Something was invalid return View(shippingDetails); } Related to: How to avoid placing domain logic in controller?

  • Service Discovery in J2ME

    - by thiagolee
    Hello, I have an application to run on a cell phone equipped with Wi-Fi and an application on a desktop which I want to communicate with. The problem is that I want to find in a Local Area Network the IP and port of the machine who has my service running. I can guarantee that there will be at maximum only one machine running it. I searched a lot for a way to do this but I ended up with nothing. I read something about WebServices, but it didn't seen to be what I wanted, what I want is really simple. I actually found a solution for it, but it can't be ported to J2ME. Anyone can help? Thanks.

  • Retrieving images when database is in remote location...

    - by sasidhar
    Hi everyone, I am developing an application using java, my application would be accessed by number of different users simultaneously and the database resides in a central server. The access of the database from remote server is handled by just giving the appropriate IP of the server in the hibernate configure file. My question is, i have to store a picture regarding each user of the database, i heard that storing the image in the database and retrieving it from the database is not advised and has negative impact on the performance. Is it so ? What are the other possible ways i can implement this ? What is the best way to do it..? Please help....

  • How to reduce latency of data sent through a REST api

    - by Sid
    I have an application which obtains data in JSON format from one of our other servers. The problem I am facing is, there is is significant delay when when requesting for this information. Since a lot of data is passed (approx 1000 records per request where each record is pretty huge) is there a way that compression would help reducing the speed. If so which compression scheme would you recommend. I read on another thread that they pattern of data also matters a lot on they type of compression that needs to be used. The pattern of data is consistent and resembles the following :desc=>some_description :url=>some_url :content=>some_content :score=>some_score :more_attributes=>more_data Can someone recommend a solution to how I could reduce this delay. They delay is approx 6-8 seconds. I'm using Ruby on Rails to develop this application and the server providing the data uses Python for the most part.

  • How do I get artifacts from one Maven module included in the resources of another in my build?

    - by Hanno Fietz
    I have Maven modules that produce a Flex application as an SWF file. I want to include that file in a web application that is made with another Maven module from the same build. I'm wondering how and at which lifecycle phase I get Maven to grab the artifact from the other module and put it insode the appropriate folder of the webapp module. Would I use a separate assembly module? The web app is running on a Jetty server in an OSGi environment (using Pax), the server side of the web app uses Struts. The final artifact as I see it would be a WAR file including my Action etc classes, JSP templates, static contents such as CSS or JS, and the SWF movies. I might be better off with these split over some other setup, but right now, I wouldn't know which.

  • Optimal search queries

    - by Macros
    Following on from my last question http://stackoverflow.com/questions/2788082/sql-server-query-performance, and discovering that my method of allowing optional parameters in a search query is sub optimal, does anyone have guidelines on how to approach this? For example, say I have an application table, a customer table and a contact details table, and I want to create an SP which allows searching on some, none or all of surname, homephone, mobile and app ID, I may use something like the following: select * from application a inner join customer c on a.customerid = a.id left join contact hp on (c.id = hp.customerid and hp.contacttype = 'homephone') left join contact mob on (c.id = mob.customerid and mob.contacttype = 'mobile') where (a.ID = @ID or @ID is null) and (c.Surname = @Surname or @Surname is null) and (HP.phonenumber = @Homphone or @Homephone is null) and (MOB.phonenumber = @Mobile or @Mobile is null) The schema used above isn't real, and I wouldn't be using select * in a real world scenario, it is the construction of the where clause I am interested in. Is there a better approach, either dynamic sql or an alternative which can achieve the same result, without the need for many nested conditionals. Some SPs may have 10 - 15 criteria used in this way

  • Setting minimum threads in thread pool

    - by expert
    I have an application with 4 worker threads from the thread pool. It was waking up every 0.5 second. as written in msdn the thread pool monitors every 0,5 second to create idle threads. I set the nuber of minimum threads to 4 and it solved the problem - no more background activity all the time. My question is - I have another applicatiopn which has the same number of threads threads-4, but here setting min thread to 4 doesn't help but when setting min thread to 5 then the background monitoring stops. What might be the difference between 2 application with the same number of threads from the thread pool- 4 threads.On one setting min threads to 4 helps and the other only setting min threads to 5 helps?

  • An explanation of memory usage on Windows server 2003

    - by Rich
    Hi, We've been working on a bit of puzzle at work. We have an application service installed on two machines, both running Windows server 2003. These services do exactly the same thing. However once loaded, one of the services uses 200mb less than the other service. We're at a bit of a loss to what might be causing this discrepancy. I was wondering if there was some kind of server setting that would cause an application to use more memory (heap block size) or anything to explain this. If anyone has any ideas on what may be causing this, or how to find out what is causing this I'd be very grateful. Cheers Rich

  • How can I start XServer in Linux through apache user triggered by Perl script running in background?

    - by Nikhil
    I am trying to launch MS Office through WINE using a PERL script hosted by apache and and triggered by other application. I am getting the following error message in log files "Application trying to create a window but no driver could not be loaded. Make sure that your X server is running and that $DISPLAY is set correctly". If I run the script directly on shell prompt using root user then WINE starts XServer properly and execute MS MSoffice in addition to that if I set xhost +local:apache on shell prompt then also it works fine. How can I start the XServer from apache user?

  • [C++] Run codes for only 60 times each second.

    - by djzmo
    Hello there, I'm creating a directx application that relies on the system time (because it must be accurate), and I need to run lines of code for 60 times each second in the background (in a thread created by boost::thread). that's equal to 60 FPS (frame per second), but without depending on the main application frame rate. //................. void frameThread() { // I want to run codes inside this loop for *exactly* 60 times in a second. // In other words, every 16.67 (1000/60) milliseconds for(;;) { DoWork(); //......... } } int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd) { initialize(); //.....stuffs boost::thread framethread(frameThread); //...... } Is there a way to do this? Any kind of help would be appreciated :)

  • How do I create a no-javascript url hash handler for my website?

    - by Kenny Bones
    Ok, I'm not sure how this is normally done. But I've got a script that basically empties a div of content and then loads content from a div from a separate webpage, without reloading the current page. This works great. It's taken from this example actually, from net tuts (great site btw) http://nettuts.s3.amazonaws.com/011_jQuerySite/sample/index.html And the guy who wrote this even though about handling the url's since the url don't change when using his method. So he wrote a javascript snippet that looks up the url and loads the content accoringly. Which is not working btw. But I was thinking about people who don't have javascript enabled, or iPhone and iPad users ;) Copying URLs and sending to a friend won't work at all. So how is this typically done? And can it be done without javascript? Possibly by php?

  • Handling multiple post-defined datasource connections based on user

    - by choudeshell
    How should I handle multiple user-connection defined datasource connection in my .NET application? To illustrate this better; the user provides three (3) pieces of information, username, password and data source name. This data source name is then looked-up in a central database telling that application which main database this user should connect to. My question is, in the DataAccess layer, should we only pass down enough information to uniquely identify that user, and query the central database each time in the DAL; or, should we provide another way to pass the datasource connection down to the DAL?
