• How to handle a C# console application terminating?

  - by Nick R

  If I have a console application, is there any way I can handle the following: Ctrl-C (I know the answer to this. Using Console.TreatControlCAsInput and Console.CancelKeyPress) Session termination, such as when someone logs off Process exit, such as when someone uses the task manager to close the application. I know that if I was writing a unix application, I would handle various signals to catch the request to close (SIGTERM from memory), but I also know I need to handle these messages pretty quickly and exit before the system does a kill -9 (SIGKILL). But for a C# console application, I'm not sure how to do this.

• struts 2 bean is not created

  - by Dewfy

  Hello colleagues! At first some precondition to my question, I'm using struts2 + tiles2 + toplink. NO spring at all. The simplest scenario - is to display list of entities on the page. To optimize resolving JPA's EntityManager I would like to create helper (JPAResourceBean) that implements lazy load of entity manager. For this purposes I'm going to use struts2's bean declaration: <bean name="myfactory" class="my.model.JPAResourceBean" scope="session" optional="false"/> Why bean is not instantiated neither in session? (I'm using s:property just for debug) ... <s:property value="#session.myfactory" default="buka.1"/> ... nor in plain bean list: ... <s:property value="#myfactory" default="buka.2"/> ... May be the second part of question is - how to resolve this bean from java code?

• Different url scheme for Zend Framework

  - by ChrisRamakers

  For our CMS we have a site manager that defines the site's tree structure (sitemap if you want to call it that). A possible url is www.example.com/our-team/developers/chris/ which would map in the tree structure to the node chris, child old developers which is in turn a child of out-team. All this is in place and working the the wonderfully implemented Nested Set behavior in doctrine. The only thing is that i'm struggling to get it working in the front end of our website. By default Zend framework's request object expects controller/action/key/value/key/value/... URI scheme but that isn't quite fitting my needs, i would like to skip the whole controller, action and key part and restrict to values. Something like value1/value2/value3/value4/... Anyone has an idea how to accomplish this?

• UnitTest++ creates cmd windows, which can't be closed

  - by Simon

  Hello, I have a setup for using UnitTest++ like this in VS2008. Sometimes the cmd window, which shows the console output of the unit tests just hangs. I can move the window, resize and stuff, but I'm unable to close it. I see the window in the App tab of the Task Manager, but not in the Process tab, "Switch to process" doesn't work either. Stop debugging or closing VS is also no help, it seems VS has lost control over this window. If this cmd window is lost, I'm unable to shutdown my computer, which is pretty annoying Any hints?

• MKReverseGeocoder delegate location?

  - by fuzzygoat

  I have a quick question regarding memory management that I am not quite sure about. I currently have a locationManager delegate that calls locationManager:didUpdateToLocation:fromLocation when it resolves the device location. My question is I am looking at adding ReverseGeoCoding after I have obtained the [newLocation coordinate] but am unsure about doing the alloc here, as each time locationManager:didUpdateToLocation:fromLocation gets called I will be alloc-ing a new MKReverseGeoCoder? // LOCATION -(void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation { // GeoCoding: MKReverseGeocoder *geoCoder = [[MKReverseGeocoder alloc] initWithCoordinate:[newLocation coordinate]]; [geoCoder setDelegate:self]; [geoCoder start]; [self foundLocation]; } Can anyone point me in the right direction with regards to this? I did try doing the alloc in application:didFinishLaunchingWithOptions: but then realised I did not have access to [newLocation coordinate]. many thanks gary

• Android process killer

  - by Martin

  I have similar question, maybe you can help. Is it possible to get list of all process which are running in the Android system, and kill some of them? I know that there are some applications (task managers), but I would like to write my own, simple application. I would like to write simple task manager, just list of all process and button which will kill some of them. Could you just write some Java methods which I can call in order to get list of process, and method for killing them. Or just give me some advices. Thanks for answers. Regards Martin

• Localize node texts in treeview using resource files

  - by Obalix

  For a project I need a tree view that allows the user to select a module, which then is displayed in a content area. The project relies heavily on localization and this is provided by the resource files. Now I discovered today, that the text that are assigned to preset tree view nodes are not contained in the resource files. So the question is whether there is a way of doing this, short of mapping the elemenst in code. I.e. assigning a name to the node, running over all nodes and pulling the resources from the resouce manager based on the node name. This is what I am currently doing, however, it just doesn't "feel" right: private void TranslateNodes(TreeNodeCollection treeNodeCollection) { var rm = Resources.ResourceManager; foreach (TreeNode node in treeNodeCollection) { node.Text = rm.GetString(node.Name + "_Text"); this.TranslateNodes(node.Nodes); } } Thanks!

• Django query: Count and Group BY

  - by Tyler Lane

  I have a query that I'm trying to figure the "django" way of doing it: I want to take the last 100 calls from Call. Which is easy: calls = Call.objects.all().order_by('-call_time')[:100] However the next part I can't find the way to do it via django's ORM. I want to get a list of the call_types and the number of calls each one has WITHIN that previous queryset i just did. Normally i would do a query like this: "SELECT COUNT(id),calltype FROM call WHERE id IN ( SELECT id FROM call ORDER BY call_time DESC LIMIT 100 ) GROUP BY calltype;" I can't seem to find the django way of doing this particular query. Here are my 2 models: class Call( models.Model ): call_time = models.DateTimeField( "Call Time", auto_now = False, auto_now_add = False ) description = models.CharField( max_length = 150 ) response = models.CharField( max_length = 50 ) event_num = models.CharField( max_length = 20 ) report_num = models.CharField( max_length = 20 ) address = models.CharField( max_length = 150 ) zip_code = models.CharField( max_length = 10 ) geom = models.PointField(srid=4326) calltype = models.ForeignKey(CallType) objects = models.GeoManager() class CallType( models.Model ): name = models.CharField( max_length = 50 ) description = models.CharField( max_length = 150 ) active = models.BooleanField() time_init = models.DateTimeField( "Date Added", auto_now = False, auto_now_add = True ) objects = models.Manager()

• Full outer join in django

  - by Ber

  How can I create a query for a full outer join across a M2M relationchip using the django QuerySet API? It that is not supported, some hint about creating my own manager to do this would be welcome. Edited to add: @S.Lott: Thanks for the enlightenment. The need for the OUTER JOIN comes from the application. It has to generate a report showing the data entered, even if it still incomplete. I was not aware of the fact that the result would be a new class/model. Your hints will help me quite a bit.

• Cross-Page communication in firefox extension

  - by OzBarry

  I have two tabs that my extension uses and I wanted to pass events back and forth between them. I've already developed a Google Chrome extension that does this via the background page api, but there doesn't seem to be an equivalent in firefox. I thought message-manager in the firefox extension docs would do the trick, but the documentation on the object is quite poor. I'd be just as happy with using one of the tabs to control the other if I can't directly import the ideas of a background page from google chrome api. Any help/guidance would be great.

• How to maintain the HTML semantics when HTML is used for drawing diagrams (like organizational chart

  - by Vijay

  I have created an organizational chart using ASP.NET on web page. The web page is using strict DOCTYPE and following W3C standards. The chart has a hierarchical layout decided by the manager field in the table that contains employees in the organization. The chart layout has nodes with employee image and other details like job title, department and contact details. Nodes are beautifully arranged and connected by lines (only horizontal or vertical or both). A lot of DIV elements are used (to avoid table) for connecting lines and arranging the chart properly. As suggested by my friend, using DIVs for connecting lines in the chart is semantically wrong. Is there a way by which I can make it semantically correct? Or, am I using HTML for the wrong purpose?

• Developer workload management software: recommendations?

  - by PaddyC

  In my place, we use two issue tracking tools, one for production bugs, and another for issues on projects in development. These tools are good for managers. However, at an individual level, other work can also arrive through desk visits, email, or the phone, and those allocating the work aren't always interested in issue tracking systems. I've recently rolled off an 18-month project where I got into a cycle of overtime, and I found that I didn't always have good visibility of all work assigned to me. As a result, I was always very busy, and felt constantly laden down with work, but didn't have the clear data to show my manager (or, ironically, the time to stop and gather the information!). A handwritten list, updated at the end of each day, is a good start, but can anyone recommend better tools to help me get a clear view of my own workload? Ideally, I'm thinking of software tools for developers, which could incorporate estimates, but all suggestions welcome. Thanks, Paddy

• How do you interface with a USB to Parallel adapter?

  - by Hans

  I'm currently doing a project where I have to interact with a circuit I made through the parallel port of a computer. However, my computer doesn't have a parallel port so I borrowed a Parallel to USB adapter cable. The cable didn't come with any drivers, but it's recognized by the device manager as a "USB Printing Support" controller, under the USB section. It seems that old parallel printers can be plugged in and work properly without any problems. So my question is, if I write a program in Java that tries to interact with a parallel port directly, will it work? And if not, can anyone give me some pointers as to what I need to do to interact with it? Thanks.

• Can nested attributes be used in combination with inheritance?

  - by FoxDemon

  I have the following classes: Project Person Person Developer Person Manager In the Project model I have added the following statements: has_and_belongs_to_many :people accepts_nested_attributes_for :people And of course the appropriate statements in the class Person. How can I add an Developer to a Project through the nested_attributes method? The following does not work: @p.people_attributes = [{:name => "Epic Beard Man", :type => "Developer"}] @p.people => [#<Person id: nil, name: "Epic Beard Man", type: nil>] As you can see the type attributes is set to nil instead of Developer.

• Annotate and Aggregate function in django

  - by thesteve

  In django I have the following tables and am trying to count the number of votes by item. class Votes(models.Model): user = models.ForeignKey(User) item = models.ForeignKey(Item) class Item(models.Model): name = models.CharField() description = models.TextField() I have the following queryset queryset = Votes.objects.values('item__name').annotate(Count('item')) that returns a list with item name and view count but not the item object. How can I set it up so that the object is returned instead of just the string value? I have been messing around with Manager and Queryset methods, that the right track? Any advice would be appreciated.

• Basic questions about SNMP

  - by David Hodgson

  Hi, I'm learning about SNMP, and writing some applications using it. I have some basic questions about the protocol: Do the agents store its state on the device itself? If there is a trap set on an agent, can you do a poll on the same OID to get the same information? Without using a mib file, is there a way to query a device for all of its information at once? If not, and you're writing your own customized manager, do you have to know the structure of what it reports up front? If you're setting up an agent to report, is there usually a way to control the frequency of how often it sends a trap? Or does it usually send a trap as often as some condition is satisfied?

• What are the requirements for an application health monitoring system?

  - by Steven A. Lowe

  What, at a minimum, should an application health-monitoring system do for you (the developer) and/or your boss (the IT Manager) and/or the oeprations (on-call) staff? What else should it do above the minimum requirements? Is monitoring the 'infrastructure' applications (ms-exchange, apache, etc.) sufficient or do individual user applications, web sites, and databases also need to be monitored? if the latter, what do you need to know about them? ADDENDUM: thanks for the input, i was really looking for application-level monitoring not infrastructure monitoring, but it is good to know about both

Can this be achieved on MigLayout or should I use some other layout manager for this frame.

• How to set the base path in IIS 7 hosting a WCF application?

  - by curiouscoder

  I've been fighting my way through the process of migrating a (previously self-hosted) WCF application to IIS7 (I've never used IIS before and I realise that this is a very simplistic question but I failed to google/SO the answer so far). My service is hosted at http://xxx.xxx.xxx.xxx/SampleWebsite/Service.svc but when I access it with ?wsdl all the references that should read http://xxx.xxx.xxx.xxx/ are actually set to the window machine's local network name (i.e. http://localpc3/). I've tried using the WCF tool to add the external IP address to the base address section under the service I'm configuring as well as a number of setting inside IIS but I can't seem to track down the correct place. Where do I set this? IIS manager, web.config, somewhere else?

• Microsoft CRM could not log you on to the system. Make sure your user record...

  "Microsoft CRM could not log you on to the system. Make sure your user record is enabled and that you have been assigned at least one security role.

Could this be a clue? What can I try?

• Is it acceptible to expect mentoring to replace many years experience?

  - by Mantorok

  Hi all Just a quick question Here's my situation: I've been maintaining, extending and creating websites against a CMS for the last 18 months In that time I've learnt a LOT more about ASP.Net, javascript, and of course the quirks of the CMS we are using My manager wants to get others involved, and I'm expected to mentor another programmer whilst they work on production code Now, I've got no problem mentoring someone and it would be great for me to not be the only one with the skillset. But what I HAVE got a problem with is mentoring someone within an agreed timescale of the piece of work (10 days in this case) AND expected to deliver the product to the same standard. I guess what I'm getting at is: 18 months experience != a few days mentoring, not to mention the level of C#/.Net/ASP.Net/Javascript required may also not be up to scratch. Am I right to think this is a little, wrong?

• console windows not close after stopping program

  - by robUK

  Hello, Visual Studio 2005 C++ Windows XP Pro I have a sample application that I am testing, that links with boost libraries. However, the program runs ok. However, when I try and stop the program by clicking the 'Stop Debugging' button. The program ends, but the console window remains open. So I have many of them, as during my testing I am starting and stopping the application. Even when I try and close it by clicking the close button it has no affect. And it doesn't seem to appear under task manager when the program ends. The only way I can close them if I reboot windows. I am thinking it might be a thread that has not closed, and maybe that is keeping the console windows open. Many thanks for any advice,
