  • How can I set up .Net unhanlded exception handling in a windows service?

    - by Mike Pateras
    protected override void OnStart(string[] args) { AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException); Thread.Sleep(10000); throw new Exception(); } void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e) { } I attached a debugger to the above code in my windows service, setting a breakpoint in CurrentDomain_UnhandledException, but it was never hit. The exception pops up saying that it is unhandled, and then the service stops. I even tried putting some code in the event handler, in case it was getting optimized away. Is this not the proper way to set up unhandled exception handling in a windows service?

  • VB.net, disable proxy for entire program

    - by Brent
    Ever since upgrading to Visual Studio 2010, I'm running into an issue where the first web request of any type (WebRequest, WebClient, etc.) hangs for about 20 seconds before completing. Subsequent calls work quickly. I've narrowed down the problem to a proxy issue. If I manually disable proxy settings, I don't experience this delay: Dim wrq As WebRequest = WebRequest.Create(Url) wrq.Proxy = Nothing What's strange is that there are no proxy settings enabled on this machine in Internet Options. What I'm wondering is if there is a way to disable proxy settings for my entire project in one shot without explicitly disabling as above for every web object. The main reason I want to be able to do this is that I'm trying to use an API (http://code.google.com/p/google-api-for-dotnet/) which uses web requests, but does not provide any way to manually disable proxy settings. Can anyone point me in the right direction? Thanks!

  • Databind List Of Objects To A WinForms DataGridView, But Not Show Certain Public Properties

    - by Pyronaut
    I'm not even sure if i'm doing this correctly. But basically I have a list of objects that are built out of a class. From there, I am binding the list to a datagrid view that is on a Windows Form (C#) From there, it shows all the public properties of the object, in the datagrid view. However there is some properties that i still need accessible from other parts of my application, but aren't really required to be visible in the DataGridView. So is there an attribute or something similar that I can write above the property to exclude it from being shown. P.S. Im binding at runtime. So i cannot edit the columns via the designer. P.P.S. Please no answers of just making public variables (Although if that is the only way, let me know :)).

  • CLLocation is not nil but trying to print it out throws EXC_BAD_ACCESS

    - by nefsu
    Sorry, this may be a noob question but I'm working with CoreLocation and this has be stumped. I'm looking up the currentLocation using a singleton that was recommended on this site and when I get the currentLocation object, it returns true to a not nil check. However, when I try to print out its description, it throws EXC_BAD_ACCESS. //WORKS Current location 8.6602e-290 NSLog(@"Current location %g",currLoc); //DOESN'T WORK NSLog(@"Current location %@",[currLoc description]); //DOESN'T WORK - Is this causing the description to fail as well? NSLog(@"Current location %g",currLoc.coordinate.latitude); Why am I able to see something on the first one but not the others? BTW, this is being run on a 3.1.2 simulator Thanks.

  • How does Fluent NHibernate support the Import Entity

    - by Bender
    I want to create a strongly type object from a fluent NHibernate query. If I were using HQL and NHibernate I belive I would need: the class for the output Namespace Model Public Class namecount Public Overridable Property lastname() as string ... Public Overridable Property lastnamecount() as integer ... Public Sub New(lastname as string, count as integer) ... End Class End Namespace an .hbm.xml file <?xml ...> <hibernate-mapping ...> <import class="model.namecount,model"> </hibernate-mapping> and of course the query _session.createquery("select new namecount(lastname, count(lastname)) ...") (The above is a paraphrased example taken from one of the 2008 SummerofNHibernate videos) I cannot find any examples of how to do this with fluent (even in C#), is it possible? If it isn't is there a VB example of how to mix Fluent and .hbm.xml

  • Displaying large file in JTextArea.

    - by Sathish Gopal
    Hi All, I'm currently working in Swing UI Assignment. This work involves showing large file content in JTextArea. The file size can be as large as 2 GB. My initial idea is to lazily load content from the file, say 1 MB of content will be shown to the user. As the user scrolls i will retrieve the next 1 MB of content to be shown. All these operation will be happening in background thread (Swing Worker). I looked at the JTextArea API, the method insert takes String and int(position of the insert) as the parameter. This will suffice, but i'm worried about performance, because the content (1 MB at a time) retrieved will have to be converted to String object. Is there any other work around or any other alternative/better solution for this.

  • How to Obtain Data to Pre-Populate Forms.

    - by Stan
    The objective is to have a form reflect user's defined constraints on a search. At first, I relied entirely upon server-side scripting to achieve this; recently I tried to shift the functionality to JavaScript. On the server side, the search parameters are stored in a ColdFusion struct which makes it particularly convenient to have the data JSON'ed and sent to the client. Then it's just a matter of separately iterating over 'checkable' and text fields to reflect the user's search parameters; jQuery proved to be exceptionally effective in simplifying the workload. One observable difference lies in performance. The second method appeared to be somewhat slower and didn't work in IE8. Evidently, the returned JSON'ed struct was seen as an empty object. I'm sure it can be fixed, though before spending any more time with it, I'm curious to hear how others would approach the task. I'd gladly appreciate any suggestions. --Stan

  • Processing potentially large STDIN data, more than once

    - by d11wtq
    I'd like to provide an accessor on a class that provides an NSInputStream for STDIN, which may be several hundred megabytes (or gigabytes, though unlikely, perhaps) of data. When I caller gets this NSInputStream it should be able to read from it without worrying about exhausting the data it contains. In other words, another block of code may request the NSInputStream and will expect to be able to read from it. Without first copying all of the data into an NSData object which (I assume) would cause memory exhaustion, what are my options for handling this? The returned NSInputStream does not have to be the same instance, it simply needs to provide the same data. The best I can come up with right now is to copy STDIN to a temporary file and then return NSInputStream instances using that file. Is this pretty much the only way to handle it? Is there anything I should be cautious of if I go the temporary file route?

  • One project in Delphi 2007 doesn't show procedure name in the IDE Obj Inspector's Events

    - by lgallion
    I have a Delphi project in 2007 that doesn't show the procedure names in the Object Inspector's Events such as Form OnClose, OnCreate or OnShow in the IDE. The code is there and if you click on OnCreate (for example) you are taken to the code and the IDE fills in the name of procedure. However on reload, the procedures are missing from the IDE again. This same project causes various error messages when Delphi closes also, but I am not sure if this is related (no other project developed under this Delphi does but this one is the largest app and uses several 3rd party add-in libraries). I have moved this app to various Delphi 2007 installations and it reacts the same, so it isn't a corrupt Delphi situation. Is there any way to rebuild or fix a corrupt project like this? Any help would be appreciated.

  • FxCop CA2000 Warning in UserControls

    - by esjr
    Running FxCop on a WebProject that contains a UserControl will result in a CA2000 Warning (Call System.IDisposable.Dispose on object) for every ServerControl (Label, TextBox,...) in that UserControl. I understand why this would happen. Replacing the 'offending' ServerControls with a PlaceHolder and then adding the Controls in code (Using...End Using) might be a way around that, but it is not always an option.But, if they are not 'kosher' why have ServerControls you can drop in your ascx/aspx in the first place ?Am I missing something ? If, like in my case, you inherit a sizeable collection of fairly complex UserControls, do I now add every 'offending' Control to the GlobalSupperssions file (that's a lot of mind numbing right-clicking) ?I do not want to suppress all CA2000 warnings since it makes perfect sense to fix them, but not in the case of ServerControls in UserControls.

    Hi guys I'm working with Zend framework and just hate the fact that I seem to encounter hundreds of exception errors like if I try to reference a non existant property of an object my application just dies and crashes.

  • ruby, rails, railscasts example gone bad

    - by Sam
    If you saw the railscasts on nested forms this is the helper method to create links dynamically. However, after I upgraded to ruby 1.9.2 and rails 3 this doesn't work and I have now idea why. def link_to_add_fields(name, f, association) new_object = f.object.class.reflect_on_association(association).klass.new fields = f.fields_for(association, new_object, :child_index => "new_#{association}") do |builder| render(association.to_s.singularize + "_fields", :f => builder) end link_to_function(name, h("add_fields(this, \"#{association}\", \"#{escape_javascript(fields)}\")")) end here is the javascript function add_fields(link, association, content) { var new_id = new Date().getTime(); var regexp = new RegExp("new_" + association, "g") $(link).up().insert({ before: content.replace(regexp, new_id) }); }

  • ASP.NET Nested Repeater Accessing elements

    - by Rich
    I have a list of Accommodation objects bound to a Repeater, and then a nested Repeater which has the various attendee groups listed [e.g. Default, Seniors, Juniors]. This is all output fine, with the values displayed as LinkButtons, which when clicked gets sent to a code-behind event handler. Here is an example of the output to give you a picture [with some er... interesting attendee group names]: In the event handler, I test the object parameter to see which Repeater has been sent, as the outer repeater's links can also be clicked [so the Accommodation would be set, but no Attendee Group]. Is there a way to get a HiddenField from the outer RepeaterItem that contains the currently clicked inner repeater's LinkButton? E.g. From the image, I click the Attending link in the Women section. So the EventArgs via FindControl can get me the hidden field which contains the Attendee Group's ID, which is good, but I also need the Accommodation ID [to know whether it was either Wimbledon Hotel Inn or New Acc]

  • Is this a good way to manage initializations of COM?

    - by BillyONeal
    Hello everyone :) I'm very new to anything involving Component Object Model, and I'm wondering if this method of managing calls to CoInitalize/CoUninitalize makes sense: COM.hpp: #pragma once namespace WindowsAPI { namespace ComponentObjectModel { class COM { COM(); ~COM(); public: static void Setup(); }; }} COM.cpp: #include <Windows.h> #include "COM.hpp" namespace WindowsAPI { namespace ComponentObjectModel { COM::COM() { if (CoInitializeEx(NULL, COINIT_APARTMENTTHREADED) != S_OK) throw std::runtime_error("Couldn't start COM!"); } COM::~COM() { CoUninitialize(); } void COM::Setup() { static COM instance; } }} Then any component that needs COM just calls COM::Setup() and forgets about it. Does this make sense or am I breaking any "rules" of COM?

  • Avoiding exceptions when uploading files in laravel

    - by occam98
    I've got a file upload field (attachment1) in a form that may or may not have a file uploaded in it when I process the form in laravel. When I'm trying to process the page, this line generates an exception: Input::upload('attachment1',path('storage').'attachments/'.$name); Here is the text of the exception: Message: Call to a member function move() on a non-object it seems that I need to check in advance to see if 'attachment1' has a file, and I found that the function Input::has_file('attachment1') is supposed to tell me whether or not 'attachment1' has a file, but even when I submit an empty form, it returns true. Also, from reading documentation, it seems that Input::upload is supposed to just return false when trying to upload a non-existant file, so why does it produce this exception instead, and how can I fix it?

  • Adjusting ComboBox DropDown Width in C#

    - by Jim Fell
    Hello. I have this code that adjusts the width of a comboBox drop-down: private void comboBox_DropDown(object sender, EventArgs e) { ComboBox senderComboBox = (ComboBox)sender; int width = senderComboBox.DropDownWidth; Graphics g = senderComboBox.CreateGraphics(); Font font = senderComboBox.Font; int vertScrollBarWidth = (senderComboBox.Items.Count > senderComboBox.MaxDropDownItems) ? SystemInformation.VerticalScrollBarWidth : 0; int newWidth; foreach (string s in ((ComboBox)sender).Items) { newWidth = (int)g.MeasureString(s, font).Width + vertScrollBarWidth; if (width < newWidth) { width = newWidth; } } senderComboBox.DropDownWidth = width; } It works great, except it expands the width of the drop-down to the right, whereas I would prefer it to expand to the left because the comboBox is located on the right side of my form. Any thoughts or suggestions you may have would be appreciated. Thanks.

  • Django : proper way to use model, duplicates!

    - by llazzaro
    Hello, I have a question about the proper, best way to manage the model. I am relative newbie to django, so I think I need to read more docs, tutorials,etc (suggestions for this would be cool!). Anyway, this is my question : I have a python web crawler, that is "connected" with django model. Crawling is done once a day, so its really common to find "duplicates". To avoid duplicates I do this : cars = Car.Objects.filter(name=crawledItem['name']) if len(cars) 0: #object already exists, update it car = cars[0] else: car = Car() #some non-relevant code here car.save() I want to know, if this is the proper/correct way to do it or its any "automatic" way to do it. Its possible to put the logic inside the Car() constructor also, should I do that? Thanks a lot!

  • Overriding equals, hashCode and toString in a Clojure deftype

    - by mikera
    I'm trying to create a new type in Clojure using deftype to implement a two dimensional (x,y) coordinate, which implements a "Location" protocol. I'd also like to have this implement the standard Java equals, hashCode and toString methods. My initial attempt is: (defprotocol Location (get-x [p]) (get-y [p]) (add [p q])) (deftype Point [#^Integer x #^Integer y] Location (get-x [p] x) (get-y [p] y) (add [p q] (let [x2 (get-x q) y2 (get-y q)] (Point. (+ x x2) (+ y y2)))) Object (toString [self] (str "(" x "," y ")")) (hashCode [self] (unchecked-add x (Integer/rotateRight y 16))) (equals [self b] (and (XXXinstanceofXXX Location b) (= x (get-x b)) (= y (get-y b))))) However the equals method still needs some way of working out if the b parameter implements the Location protocol. What is the right approach? Am I on the right track?
