  • Why doesn't my Perl script start under FastCGI?

    - by Sam
    I am getting this error in error_log one of my Perl CGI application. I am pretty sure I haven't changed my script at all and all of a sudden i have started getting this error. This is what I see in error_log: [Wed Jul 8 15:18:20 2009] [warn] FastCGI: server "/local/web/test/cgi-bin/test.pl" (pid 17033) terminated by calling exit with status '255' [Wed Jul 8 15:18:20 2009] [warn] FastCGI: server "/local/web/test/cgi-bin/test.pl" has failed to remain running for 30 seconds given 3 attempts, its restart interval has been backed off to 600 seconds (The snippet was edited for clarity) Also, the AddHandler line for FastCGI exists in the config file. Can any tell me the possible reasons for this error? There is nothing recorded in Apache logs.

  • NSTableView doesn't populate with array objects until a new object is added via the controller

    - by Luke
    I have an NSTableView and an array controller set up as shown here, using cocoa bindings: https://developer.apple.com/library/mac/documentation/Cocoa/Conceptual/TableView/PopulatingViewTablesWithBindings/PopulatingView-TablesWithBindings.html#//apple_ref/doc/uid/10000026i-CH13-SW3 In my app delegate during applicationDidFinishLaunching I have the following snippet in here, initialising the array and filling it with objects array = [[NSMutableArray alloc] init]; SomeObject* foo = [[Object alloc] init]; foo.text = @"sup"; [array addObject:foo]; //Repeat this a few times However, when I build the app and run it I end up with an empty table. However, if I bind a button to the array controller's add: input and click it during runtime (this adds a new object to the array and table) then the table will show the new object first, with the objects added during applicationDidFinishLaunching following it. Why does this happen? And is there a way to make my table populate without having to add an element first?

  • Redirect in Application_Error redundant if using customErrors?

    - by Ek0nomik
    If I have a customErrors section in my Web.config that says to redirect to Error.html, then putting code in the Application_Error method in the Global.asax to redirect to Error.html is redundant is it not? Technically, I could bypass the Web.config by redirecting to a different page in the Application_Error method if I wanted to, but since I don't want to go to a separate page I don't think I need the code.

  • it takes 2 seconds to compile a hello world C++ project in netbeans (windows)

    - by Ethan
    I used code:blocks as the C++ IDE on Windows. I switched to netbeans 6.8 (with C/C++ plugin, MinGW, MSYS) recently, because netbeas have the nice feature of "checking syntax errors when typing" (same as working on Java or PHP projects). But the painful thing is that, it takes 2 seconds to compile a simple hello world project in netbeans. Any trick to make it as fast as code:blocks, or at least make the compiling time no more than 0.5 second?

  • Spring 3.0 MVC mvc:view-controller tag

    - by gouki
    Here's a snippet of my mvc-config.xml <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/views/"/> <property name="suffix" value=".jsp"/> </bean> <mvc:view-controller path="/index" view-name="welcome"/> <mvc:view-controller path="/static/login" view-name="/static/login"/> <mvc:view-controller path="/login" view-name="/static/login"/> I have the welcome.jsp on /WEB-INF/view/ directory and login.jsp on /WEB-INF/view/static/. This work for '/index' and '/login' paths. But I'm getting 404 response for '/static/login' when invoked from the browser. I'm expecting that '/static/login/' and '/login' should behave the same. What could be wrong here? Would appreciate any help. Thanks!

  • How can I execute a non-blocking System.Beep() in C#?

    - by Siracuse
    In C# I can perform a Console.Beep(). However, if you specify a duration of say 1000, or 1 second, it will not execute the next line of code until that second passes. Is there any way possible to execute Console.Beep() in a non-blocking fashion so it will continue to beep and still continue executing the code below it while beeping?

  • Working with the IE cache from C# & WPF

    - by Eric
    I'm writing a program in C# using the WPF framework. I need to display images, and I'd like to cache them to avoid downloading them constantly. I can code my own cache, however, IE already has a caching system. I can find code to read entries out of the IE cache, however I've found nothing dealing with the issue of adding items to the cache. Is there a good way to do it, or should I just implement a separate cache?

    - by JonF
    Does anyone have some recommendations on how I can find databases for random things that I might want to use in my application. For example, a database of zip code locations, area code cities, car engines, IP address locations, or whatever. I'm just asking generally when you decide you need a bunch of data where are some good places to start looking other than google?

  • Can I change properties of inherited controls at design time?

    - by Jeff Stock
    I am using visual inheritance and was wondering if there is a way to change the properties of inherited controls at design time, preferably in the form designer. If not, then in the designer code. I have my control declared as Public in the base class. I can access it in the child form code, but not in the form designer. Is this just not possible?

  • Translating a C# WCF app into Visual Basic

    - by MikeG
    I'm trying to write a simple/small Windows Communication Foundation service application in Visual Basic (but I am very novice in VB) and all the good examples I've found on the net are written in C#. So far I've gotten my WCF service application working but now I'm trying to add callback functionality and the program has gotten more complicated. In the C# example code I understand how everything works but I am having trouble translating into VB the portion of code that uses a delegate. Can someone please show the VB equivalent? Here is the C# code sample I'm using for reference: namespace WCFCallbacks { using System; using System.ServiceModel; [ServiceContract(CallbackContract = typeof(IMessageCallback))] public interface IMessage { [OperationContract] void AddMessage(string message); [OperationContract] bool Subscribe(); [OperationContract] bool Unsubscribe(); } interface IMessageCallback { [OperationContract(IsOneWay = true)] void OnMessageAdded(string message, DateTime timestamp); } } namespace WCFCallbacks { using System; using System.Collections.Generic; using System.ServiceModel; public class MessageService : IMessage { private static readonly List<IMessageCallback> subscribers = new List<IMessageCallback>(); //The code in this AddMessage method is what I'd like to see re-written in VB... public void AddMessage(string message) { subscribers.ForEach(delegate(IMessageCallback callback) { if (((ICommunicationObject)callback).State == CommunicationState.Opened) { callback.OnMessageAdded(message, DateTime.Now); } else { subscribers.Remove(callback); } }); } public bool Subscribe() { try { IMessageCallback callback = OperationContext.Current.GetCallbackChannel<IMessageCallback>(); if (!subscribers.Contains(callback)) subscribers.Add(callback); return true; } catch { return false; } } public bool Unsubscribe() { try { IMessageCallback callback = OperationContext.Current.GetCallbackChannel<IMessageCallback>(); if (!subscribers.Contains(callback)) subscribers.Remove(callback); return true; } catch { return false; } } } } I was thinking I could do something like this but I don't know how to pass the message string from AddMessage to DoSomething... Dim subscribers As New List(Of IMessageCallback) Public Sub AddMessage(ByVal message As String) Implements IMessage.AddMessage Dim action As Action(Of IMessageCallback) action = AddressOf DoSomething subscribers.ForEach(action) 'Or this instead of the above three lines: 'subscribers.ForEach(AddressOf DoSomething) End Sub Public Sub DoSomething(ByVal callback As IMessageCallback) 'I am also confused by: '((ICommunicationObject)callback).State 'Is that casting the callback object as type ICommunicationObject? 'How is that done in VB? End Sub

  • Would this union work if char had stricter alignment requirements than int?

    - by paxdiablo
    Recently I came across the following snippet, which is an attempt to ensure all bytes of i (nad no more) are accessible as individual elements of c: union { int i; char c[sizeof(int)]; }; Now this seems a good idea, but I wonder if the standard allows for the case where the alignment requirements for char are more restrictive than that for int. In other words, is it possible to have a four-byte int which is required to be aligned on a four-byte boundary with a one-byte char (it is one byte, by definition, see below) required to be aligned on a sixteen-byte boundary? And would this stuff up the use of the union above? Two things to note. I'm talking specifically about what the standard allows here, not what a sane implementor/architecture would provide. I'm using the term "byte" in the ISO C sense, where it's the width of a char, not necessarily 8 bits.

  • Is it better to alloc/dealloc new UIBarButtonItems when toggling Edit/Done? Why?

    - by cambria
    Apple's documentation implies that for a UITableView editable with an "Edit/Done" button, you should create and destroy the button each time it's toggled. Here's a snippet of code "BonjourWeb" sample code project that does this: if (editing) { // Add the "done" button to the navigation bar UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(doneAction:)]; self.navigationItem.leftBarButtonItem = doneButton; [doneButton release]; [self addAddButton:YES]; } else { if ([self.customs count]) { // Add the "edit" button to the navigation bar UIBarButtonItem *editButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemEdit target:self action:@selector(editAction:)]; self.navigationItem.leftBarButtonItem = editButton; [editButton release]; } Is this really better than just editing the title of the button? Is there some performance optimisation that I'm not seeing? Or is this just bad example source?

  • nested updatepanels

    - by Elenor
    When I put nested updatepanels in outer updatepanel, then in code, it shows that outer panel is around the code of all nested panels while design mode shows outer updatepanel is drawn like one row on top of page and nested updatepanels are drawn below that outside of outer updatepanel. Is this normal behavior or there is some problem in my implementation?

  • Hash default value not being used

    - by ba
    Today I tried the following snippets of code and I don't understand why I get different results between them. As far as I can understand they are the same. One uses the default value off Hash and the other snippet creates an empty array for the key before it'll be accessed. Anyone who understands what's going on? :) # Hash default if the key doesn't have a value set is an empty Array a = Hash.new([]) a[:key] << 2 # => [2] p a # => {} nil p a[:key] # => [2] # Explicitly add an array for all nodes before creating b = Hash.new b[:key] ||= [] b[:key] << 2 # => [2] p b # => {:key=>[2]}

  • jQuery replacing an image inside a .net datalist

    - by user359409
    (submit said I was trying to post an image so I've changed image everywhere to ix I am trying to get jQuery to replace an ix inside a datalist. The original ix is the thumbnail ix of a product on a category page. The small ix I am clicking on are swatch ix for the different colors of a product. I can get it to work using a div tag around the ix tag inside the ItemTemplate. I don't need to use a div tag if I can get the imagesx to swap- I was just using it because that is sample code I found and it works for the first product in the category. <asp:HyperLink ID="ProductNav" runat="server" NavigateUrl='<%#Eval("NavigateUrl") %>'> <div id="ladiv" runat="server"> <asp:Ixx runat="server" ID="ProdThumb" /> </div> </asp:HyperLink> <asp:PlaceHolder ID="phSwatches" runat="server"></asp:PlaceHolder> The ProdThumb ix is added from the code behind and the swatches are added from the code behind swatches.Controls.Add(new LiteralControl("<table><tr>")); foreach(OptionChoice optionChoice in option.Choices) { string swatchThumbnail = string.Format("<ix ID=\"{0}\" src=\"{1}\" border=\"0\" class=\"{2}\" />","swatch" + optionChoice.OptionChoiceId.ToString(), ResolveUrl(optionChoice.ThumbnailUrl),"imgthumb"); swatches.Controls.Add(new LiteralControl("<td>")); swatches.Controls.Add(new LiteralControl(swatchThumbnail)); swatches.Controls.Add(new LiteralControl("</td>")); } swatches.Controls.Add(new LiteralControl("</tr></table>")); prodThumb.IxUrl = product.ThumbnailUrl; prodThumb.AlternateText = product.ThumbnailAltText; prodThumb.CssClass = "Thumbnail"; The jQuery is: $(function() { $("ix.imgthumb").click(function(e) { var t = $(this); var newImg = ''; $('#ladiv') .html($(newImg) ); }); }); </script> Both images are named similar, except the swatch contains "sws" and the larger one is the some only with "swl". I have spent several days searching but am not able to get it to work. If I try something like $("#<%=ladiv.ClientID %") the code can't find it. I appreciate any help.
