• Compiling ruby1.9.1 hangs and fills swap!

  - by nfm

  I'm compiling Ruby 1.9.1-p376 under Ubuntu 8.04 server LTS (64-bit), by doing the following: $ ./configure $ make $ sudo make install ./configure works without complaints. make hangs indefinitely until all my RAM and swap is gone. It get stuck after the following output: compiling ripper make[1]: Entering directory `/tmp/ruby1.9.1/ruby-1.9.1-p376/ext/ripper' gcc -I. -I../../.ext/include/x86_64-linux -I../.././include -I../.././ext/ripper -I../.. -I../../. -DRUBY_EXTCONF_H=\"extconf.h\" -fPIC -O2 -g -Wall -Wno-parentheses -o ripper.o -c ripper.c If I run the gcc command by hand, with the -v argument to get verbose output, it hangs after the following: Using built-in specs.

• How to configure the roles in my tomcat application to work with JNDI(WIN AUTH)

  - by Itay Levin

  Hi, I'm trying to change the authentication mode of my application from JDBC-REALM to JNDI-REALM. I configured the following section inside the Server.xml <Realm className="org.apache.catalina.realm.JNDIRealm" debug="99" connectionURL="ldap://****:389/DC=onsetinc,DC=com??sAMccountName?sub?(objectClass=*)" connectionName="[email protected]" connectionPassword="password" userBase="CN=Users" referrals="follow" userSearch="(sAMAccountName={0})" userSubtree="true" roleBase="CN=Users" roleName="name" roleSubtree="true" roleSearch="(member={1})"/> I have also configured the web.xml under my appfolder to contain the following: <security-role> <role-name>Admin</role-name> </security-role> <security-role> <role-name>WaterlooUsers</role-name> </security-role> <security-constraint> <web-resource-collection> <web-resource-name>Tube</web-resource-name> <url-pattern>/ComposeMessage.jsp</url-pattern> <url-pattern>/PageStatus.jsp</url-pattern> <url-pattern>/UserStatus.jsp</url-pattern> <url-pattern>/SearchEC.jsp</url-pattern> <url-pattern>/SearchEC2.jsp</url-pattern> <url-pattern>/SearchMessageStatisticsEC.jsp</url-pattern> <url-pattern>/SearchMessageStatus.jsp</url-pattern> <url-pattern>/SearchMessageStatisticsPager.jsp</url-pattern> <url-pattern>/SearchPageStatus.jsp</url-pattern> </web-resource-collection> <auth-constraint> <role-name>WaterlooUsers</role-name> </auth-constraint> </security-constraint> In my Active directory i have created a new group called WaterlooUsers It's distinguish name is : distinguishedName: CN=WaterlooUsers,CN=Users,DC=onsetinc,DC=com It has a property member which contains the following user: member: CN=Itay Levin,CN=Users,DC=onsetinc,DC=com (which is my user) My record on the active directory looks like that: sAMAccountName: itayL distinguishedName: CN=Itay Levin,CN=Users,DC=onsetinc,DC=com memberOf: CN=WaterlooUsers,CN=Users,DC=onsetinc,DC=com and when i get the popup for user/password i enter the username "ItayL" in the authentication message box (and my password) I have 2 questions: How do i configure correctly the roles parameters correctly in the Realm section in the server.xml to enable me to both authenticate and authorize both this group of users WaterlooUsers and also assign them to the appropriate role so that they can see all the relevant pages in my website. - currently it seems that all the Users in my domain are authenticated to the site but get the http-403 Error and can't access any of the pages in the site. I also want to be able to create 2 different set of roles in my site - which can both have access to the same pages - but will see different things on the page. (for instance adding some administrative ability to the admin) Hope it was clear enough and not too long. Thanks in advance, Itay

• Writing a code example

  - by Stefano Borini

  I would like to have your feedback regarding code examples. One of the most frustrating experiences I sometimes have when learning a new technology is finding useless examples. I think an example as the most precious thing that comes with a new library, language, or technology. It must be a starting point, a wise and unadulterated explanation on how to achieve a given result. A perfect example must have the following characteristics: Self contained: it should be small enough to be compiled or executed as a single program, without dependencies or complex makefiles. An example is also a strong functional test if you correctly installed the new technology. The more issues could arise, the more likely is that something goes wrong, and the more difficult is to debug and solve the situation. Pertinent: it should demonstrate one, and only one, specific feature of your software/library, involving the minimal additional behavior from external libraries. Helpful: the code should bring you forward, step by step, using comments or self-documenting code. Extensible: the example code should be a small “framework” or blueprint for additional tinkering. A learner can start by adding features to this blueprint. Recyclable: it should be possible to extract parts of the example to use in your own code Easy: An example code is not the place to show your code-fu skillz. Keep it easy. helpful acronym: SPHERE. Prototypical examples of violations of those rules are the following: Violation of self-containedness: an example spanning multiple files without any real need for it. If your example is a python program, keep everything into a single module file. Don’t sub-modularize it. In Java, try to keep everything into a single class, unless you really must partition some entity into a meaningful object you need to pass around (and java mandates one class per file, if I remember correctly). Violation of Pertinency: When showing how many different shapes you can draw, adding radio buttons and complex controls with all the possible choices for point shapes is a bad idea. You de-focalize your example code, introducing code for event handling, controls initialization etc., and this is not part the feature you want to demonstrate, they are unnecessary noise in the understanding of the crucial mechanisms providing the feature. Violation of Helpfulness: code containing dubious naming, wrong comments, hacks, and functions longer than one page of code. Violation of Extensibility: badly factored code that have everything into a single function, with potentially swappable entities embedded within the code. Example: if an example reads data from a file and displays it, create a method getData() returning a useful entity, instead of opening the file raw and plotting the stuff. This way, if the user of the library needs to read data from a HTTP server instead, he just has to modify the getData() module and use the example almost as-is. Another violation of Extensibility comes if the example code is not under a fully liberal (e.g. MIT or BSD) license. Violation of Recyclability: when the code layout is so intermingled that is difficult to easily copy and paste parts of it and recycle them into another program. Again, licensing is also a factor. Violation of Easiness: Yes, you are a functional-programming nerd and want to show how cool you are by doing everything on a single line of map, filter and so on, but that could not be helpful to someone else, who is already under pressure to understand your library, and now has to understand your code as well. And in general, the final rule: if it takes more than 10 minutes to do the following: compile the code, run it, read the source, and understand it fully, it means that the example is not a good one. Please let me know your opinion, either positive or negative, or experience on this regard.

• Problem using form builder & DOM manipulation in Rails with multiple levels of nested partials

  - by Chris Hart

  I'm having a problem using nested partials with dynamic form builder code (from the "complex form example" code on github) in Rails. I have my top level view "new" (where I attempt to generate the template): <% form_for (@transaction_group) do |txngroup_form| %> <%= txngroup_form.error_messages %> <% content_for :jstemplates do -%> <%= "var transaction='#{generate_template(txngroup_form, :transactions)}'" %> <% end -%> <%= render :partial => 'transaction_group', :locals => { :f => txngroup_form, :txn_group => @transaction_group }%> <% end -%> This renders the transaction_group partial: <div class="content"> <% logger.debug "in partial, class name = " + txn_group.class.name %> <% f.fields_for txn_group.transactions do |txn_form| %> <table id="transactions" class="form"> <tr class="header"><td>Price</td><td>Quantity</td></tr> <%= render :partial => 'transaction', :locals => { :tf => txn_form } %> </table> <% end %> <div>&nbsp;</div><div id="container"> <%= link_to 'Add a transaction', '#transaction', :class => "add_nested_item", :rel => "transactions" %> </div> <div>&nbsp;</div> ... which in turn renders the transaction partial: <tr><td><%= tf.text_field :price, :size => 5 %></td> <td><%= tf.text_field :quantity, :size => 2 %></td></tr> The generate_template code looks like this: def generate_html(form_builder, method, options = {}) options[:object] ||= form_builder.object.class.reflect_on_association(method).klass.new options[:partial] ||= method.to_s.singularize options[:form_builder_local] ||= :f form_builder.fields_for(method, options[:object], :child_index => 'NEW_RECORD') do |f| render(:partial => options[:partial], :locals => { options[:form_builder_local] => f }) end end def generate_template(form_builder, method, options = {}) escape_javascript generate_html(form_builder, method, options) end (Obviously my code is not the most elegant - I was trying to get this nested partial thing worked out first.) My problem is that I get an undefined variable exception from the transaction partial when loading the view: /Users/chris/dev/ss/app/views/transaction_groups/_transaction.html.erb:2:in _run_erb_app47views47transaction_groups47_transaction46html46erb_locals_f_object_transaction' /Users/chris/dev/ss/app/helpers/customers_helper.rb:29:in generate_html' /Users/chris/dev/ss/app/helpers/customers_helper.rb:28:in generate_html' /Users/chris/dev/ss/app/helpers/customers_helper.rb:34:in generate_template' /Users/chris/dev/ss/app/views/transaction_groups/new.html.erb:4:in _run_erb_app47views47transaction_groups47new46html46erb' /Users/chris/dev/ss/app/views/transaction_groups/new.html.erb:3:in _run_erb_app47views47transaction_groups47new46html46erb' /Users/chris/dev/ss/app/views/transaction_groups/new.html.erb:1:in _run_erb_app47views47transaction_groups47new46html46erb' /Users/chris/dev/ss/app/controllers/transaction_groups_controller.rb:17:in new' I'm pretty sure this is because the do loop for form_for hasn't executed yet (?)... I'm not sure that my approach to this problem is the best, but I haven't been able to find a better solution for dynamically adding form partials to the DOM. Basically I need a way to add records to a has_many model dynamically on a nested form. Any recommendations on a way to fix this particular problem or (even better!) a cleaner solution are appreciated. Thanks in advance. Chris

• Flex/PHP/XML data issue

  - by reado

  I have built a simple application in Flex. When the application loads, a GET request is made to the xmlService.php file with parameters "fetchData=letters". This tells the PHP to return the XML code. In Flex Debug I can see the XML data being sent by the PHP to the flex client. What I need it to do is populate the first drop down box (id="letter") with this data, however nothing is being received by Flex. I added an Alert.show() to check what was being returned but when the application runs, the alert is blank. Can anyone help? Thanks in advance.

• Why do I get a NullReferenceException when using a style on a ContentPresenter?

  - by Robert Rossney

  I've created this template, which uses a style applied to the ContentPresenter so that I can bind the data object's Column property to Grid.Column, allowing the items to determine for themselves which column of the Grid they go into: <DataTemplate DataType="{x:Type local:MyObject}"> <ItemsControl ItemsSource="{Binding Items}"> <ItemsControl.Resources> <Style TargetType="{x:Type ContentPresenter}"> <Setter Property="Grid.Column" Value="{Binding Column}" /> </Style> </ItemsControl.Resources> <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="*" /> <ColumnDefinition Width="*" /> <ColumnDefinition Width="*" /> </Grid.ColumnDefinitions> </Grid> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> </ItemsControl> </DataTemplate> When I run the program, I get a NullReferenceException. The beginning of the hilariously long stack trace: at System.Windows.StyleHelper.ApplyAutoAliasRules(OptimizedTemplateContent optimizedTemplateContent, HybridDictionary childIndexFromChildID, FrameworkTemplate frameworkTemplate, FrugalStructList`1& childRecordFromChildIndex, FrugalStructList`1& triggerSourceRecordFromChildIndex, FrugalStructList`1& resourceDependents, HybridDictionary& dataTriggerRecordFromBinding, Boolean& hasInstanceValues) at System.Windows.StyleHelper.ProcessTemplateContent(FrameworkTemplate frameworkTemplate, FrugalStructList`1& childRecordFromChildIndex, FrugalStructList`1& triggerSourceRecordFromChildIndex, FrugalStructList`1& resourceDependents, ItemStructList`1& eventDependents, HybridDictionary& dataTriggerRecordFromBinding, HybridDictionary childIndexFromChildID, Boolean& hasInstanceValues) at System.Windows.StyleHelper.SealTemplate(FrameworkTemplate frameworkTemplate, Boolean& isSealed, FrameworkElementFactory templateRoot, TriggerCollection triggers, ResourceDictionary resources, HybridDictionary childIndexFromChildID, FrugalStructList`1& childRecordFromChildIndex, FrugalStructList`1& triggerSourceRecordFromChildIndex, FrugalStructList`1& containerDependents, FrugalStructList`1& resourceDependents, ItemStructList`1& eventDependents, HybridDictionary& triggerActions, HybridDictionary& dataTriggerRecordFromBinding, Boolean& hasInstanceValues, EventHandlersStore& eventHandlersStore) at System.Windows.FrameworkTemplate.Seal() at System.Windows.StyleHelper.UpdateTemplateCache(FrameworkElement fe, FrameworkTemplate oldTemplate, FrameworkTemplate newTemplate, DependencyProperty templateProperty) at System.Windows.Controls.ContentPresenter.OnTemplateChanged(DependencyObject d, DependencyPropertyChangedEventArgs e) at System.Windows.DependencyObject.OnPropertyChanged(DependencyPropertyChangedEventArgs e) at System.Windows.FrameworkElement.OnPropertyChanged(DependencyPropertyChangedEventArgs e) at System.Windows.DependencyObject.NotifyPropertyChange(DependencyPropertyChangedEventArgs args) ...etc. It's not the binding. I still get the error if I explicitly set the value in the style's setter to 0, say. And the error vanishes if I remove the style, though then all of the items end up in column 0. What's going on here? And how do I debug a problem like this?

• Why is my code returning a Null Object Refrence error when using WatIn?

  - by Fuzz Evans

  I keep getting a Null Object Refrence Error, but can't tell why. I have a CSV file that contains 100 urls. The file is read into an array called "lines". public partial class Form1 : System.Windows.Forms.Form { string[] lines; public Form1() ... private void ReadLinksIntoMemory() { //this reads the chosen csv file into our "lines" array //and splits on comma's and new lines to create new objects within the array using (StreamReader sr = new StreamReader(@"C:\temp.csv")) { //reads everything in our csv into 1 long line string fileContents = sr.ReadToEnd(); //splits the 1 long line read in into multiple objects of the lines array lines = fileContents.Split(new string[] { ",", Environment.NewLine }, StringSplitOptions.RemoveEmptyEntries); sr.Dispose(); } } The next part is where I get the null object error. When I try to use WatIn to go to the first item in the lines array it says I'm referencing a null object. private void GoToEditLinks() { for (int i = 0; i < lines.Length; i++) { //go to each link sequentially myIE.GoTo(lines[i].ToString()); //sleep so we can make sure the page loads System.Threading.Thread.Sleep(5000); } } When I debug the code it says that the GoTo request calls lines which is null. It seems like I need to declare the array, but don't I need to tell it an exact size to do that? Example: lines = new string[10] I thought I could use the lines.Length to tell it how big to make the array but that didn't work. What is weird to me is I can use the following code without problem: //returns the accurate number of urls that were in the CSV we read in earlier txtbx1.text = lines.Length; //or //this returns the last entry in the csv, as well as the last entry in the array TextBox2.Text = lines[lines.Length - 1]; I am confused why the array clearly has items in it, they can be called to fill a text box, but when I try to call them in my for loop it says its a null reference? UPDATE: By placing my cursor on both calls to lines and pressing f12 I find they both go to the same instance. The thought next is that I am not calling ReadLinksIntoMemory in time, below is my code: private void button1_Click(object sender, EventArgs e) { button1.Enabled = false; ReadLinksIntoMemory(); GoToEditLinks(); button1.Enabled = true; } Unless I'm mistaken the code says that the ReadLinksIntoMemory method must complete before GoToEditLinks can be called? If ReadLinksIntoMemory didn't finish in time I shouldn't be able to fill my text boxes with the lines array length and/or last entry. UPDATE: Stepping into the method GoToEditLinks() I see that lines is null before it calls: myIE.GoTo(lines[i]); but when it hits the goto command the value changes from null to the url it is suppose to go to, but at that same time it gives me the null object error? UPDATE: I added a IsNullOrEmpty check method and lines array passes it without any issue. I'm beginning to think it is an issue with WatIn and the myIE.GoTo command. I think this is the stack trace/call stack? Program.exe!Program.Form1.GoToEditLinks() Line 284 C# Program.exe!Program.Form1.button1_Click(object sender, System.EventArgs e) Line 191 + 0x8 bytes C# [External Code] Program.exe!Program.Program.Main() Line 18 + 0x1d bytes C# [External Code]

• Problem with a blocking network task

  - by user326967

  Hello everyone. I'm new in Java so please forgive any obscene errors that I may make :) I'm developing a program in Java that among other things it should also handle clients that will connect to a server. The server has 3 threads running, and I have created them in the following way : DaemonForUI du; DaemonForPort da; DaemonForCheck dc; da = new DaemonForPort(3); dc = new DaemonForCheck(5); du = new DaemonForUI(7); Thread t_port = new Thread(da); Thread t_check = new Thread(dc); Thread t_ui = new Thread(du); t_port.setName("v1.9--PORTd"); t_check.setName("v1.9-CHECKd"); t_ui.setName("v1.9----UId"); t_port.start(); t_check.start(); t_ui.start(); Each thread handles a different aspect of the complete program. The thread t_ui is responsible to accept asynchronous incoming connections from clients, process the sent data and send other data back to the client. When I remove all the commands from the previous piece of code that has to with the t_ui thread, everything runs ok which in my case means that the other threads are printing their debug messages. If I set the t_ui thread to run too, then the whole program blocks at the "accept" of the t_ui thread. After reading at online manuals I saw that the accepted connections should be non-blocking, therefore use something like that : public ServerSocketChannel ssc = null; ssc = ServerSocketChannel.open(); ssc.socket().bind(new InetSocketAddress(port)); ssc.configureBlocking(false); SocketChannel sc = ssc.accept(); if (sc == null) { ; } else { System.out.println("The server and client are connected!"); System.out.println("Incoming connection from: " + sc.socket().getRemoteSocketAddress()); in = new DataInputStream(new BufferedInputStream(sc.socket().getInputStream())); out = new DataOutputStream(new BufferedOutputStream(sc.socket().getOutputStream())); //other magic things take place after that point... The thread for t_ui is created as follows : class DaemonForUI implements Runnable{ private int cnt; private int rr; public ListenerForUI serverListener; public DaemonForUI(int rr){ cnt = 0; this.rr = rr; serverListener = new ListenerForUI(); } public static String getCurrentTime() { final String DATE_FORMAT_NOW = "yyyy-MM-dd HH:mm:ss"; Calendar cal = Calendar.getInstance(); SimpleDateFormat sdf = new SimpleDateFormat(DATE_FORMAT_NOW); return (sdf.format(cal.getTime())); } public void run() { while(true) { System.out.println(Thread.currentThread().getName() + "\t (" + cnt + ")\t (every " + rr + " sec) @ " + getCurrentTime()); try{ Thread.sleep(rr * 1000); cnt++; } catch (InterruptedException e){ e.printStackTrace(); } } } } Obviously, I'm doing something wrong at the creation of the socket or at the use of the thread. Do you know what is causing the problem? Every help would be greatly appreciated.

• How can I read this IIS error log?

  - by Victor Rodrigues

  I'm using Debug Diagnostic Tool, trying to understand why around 5% of the requests that are sent to my webservice just crash, without necessarily throw any error inside my application. One of the errors this tool took is below. Can anyone here understand exactly what could be happening? Thanks!

• Need some help deciphering a line of assembler code, from .NET JITted code

  - by Lasse V. Karlsen

  In a C# constructor, that ends up with a call to this(...), the actual call gets translated to this: 0000003d call dword ptr ds:[199B88E8h] What is the DS register contents here? I know it's the data-segment, but is this call through a VMT-table or similar? I doubt it though, since this(...) wouldn't be a call to a virtual method, just another constructor. I ask because the value at that location seems to be bad in some way, if I hit F11, trace into (Visual Studio 2008), on that call-instruction, the program crashes with an access violation. The code is deep inside a 3rd party control library, where, though I have the source code, I don't have the assemblies compiled with enough debug information that I can trace it through C# code, only through the disassembler, and then I have to match that back to the actual code. The C# code in question is this: public AxisRangeData(AxisRange range) : this(range, range.Axis) { } Reflector shows me this IL code: .maxstack 8 L_0000: ldarg.0 L_0001: ldarg.1 L_0002: ldarg.1 L_0003: callvirt instance class DevExpress.XtraCharts.AxisBase DevExpress.XtraCharts.AxisRange::get_Axis() L_0008: call instance void DevExpress.XtraCharts.Native.AxisRangeData::.ctor(class DevExpress.XtraCharts.ChartElement, class DevExpress.XtraCharts.AxisBase) L_000d: ret It's that last call there, to the other constructor of the same class, that fails. The debugger never surfaces inside the other method, it just crashes. The disassembly for the method after JITting is this: 00000000 push ebp 00000001 mov ebp,esp 00000003 sub esp,14h 00000006 mov dword ptr [ebp-4],ecx 00000009 mov dword ptr [ebp-8],edx 0000000c cmp dword ptr ds:[18890E24h],0 00000013 je 0000001A 00000015 call 61843511 0000001a mov eax,dword ptr [ebp-4] 0000001d mov dword ptr [ebp-0Ch],eax 00000020 mov eax,dword ptr [ebp-8] 00000023 mov dword ptr [ebp-10h],eax 00000026 mov ecx,dword ptr [ebp-8] 00000029 cmp dword ptr [ecx],ecx 0000002b call dword ptr ds:[1889D0DCh] // range.Axis 00000031 mov dword ptr [ebp-14h],eax 00000034 push dword ptr [ebp-14h] 00000037 mov edx,dword ptr [ebp-10h] 0000003a mov ecx,dword ptr [ebp-0Ch] 0000003d call dword ptr ds:[199B88E8h] // this(range, range.Axis)? 00000043 nop 00000044 mov esp,ebp 00000046 pop ebp 00000047 ret Basically what I'm asking is this: What the purpose of the ds:[ADDR] indirection here? VMT-table is only for virtual isn't it? and this is constructor Could the constructor have yet to be JITted, which could mean that the call would actually call through a JIT shim? I'm afraid I'm in deep water here, so anything might and could help. Edit: Well, the problem just got worse, or better, or whatever. We are developing the .NET feature in a C# project in a Visual Studio 2008 solution, and debugging and developing through Visual Studio. However, in the end, this code will be loaded into a .NET runtime hosted by a Win32 Delphi application. In order to facilitate easy experimentation of such features, we can also configure the Visual Studio project/solution/debugger to copy the produced dll's to the Delphi app's directory, and then execute the Delphi app, through the Visual Studio debugger. Turns out, the problem goes away if I run the program outside of the debugger, but during debugging, it crops up, every time. Not sure that helps, but since the code isn't slated for production release for another 6 months or so, then it takes some of the pressure off of it for the test release that we have soon. I'll dive into the memory parts later, but probably not until over the weekend, and post a followup.

• How can I get my Web API app to run again after upgrading to MVC 5 and Web API 2?

  - by Clay Shannon

  I upgraded my Web API app to the funkelnagelneu versions using this guidance: http://www.asp.net/mvc/tutorials/mvc-5/how-to-upgrade-an-aspnet-mvc-4-and-web-api-project-to-aspnet-mvc-5-and-web-api-2 However, after going through the steps (it seems all this should be automated, anyway), I tried to run it and got, "A project with an Output Type of Class Library cannot be started directly" What in Sam Hills Brothers Coffee is going on here? Who said this was a class library? So I opened Project Properties, and changed it (it was marked as "Class Library" for some reason - it either wasn't yesterday, or was and worked fine) to an Output Type of "Windows Application" ("Console Application" and "Class Library" being the only other options). Now it won't compile, complaining: "*Program 'c:\Platypus_Server_WebAPI\PlatypusServerWebAPI\PlatypusServerWebAPI\obj\Debug\PlatypusServerWebAPI.exe' does not contain a static 'Main' method suitable for an entry point...*" How can I get my Web API app back up and running in view of this quandary? UPDATE Looking in packages.config, two entries seem chin-scratch-worthy: <package id="Microsoft.AspNet.Providers" version="1.2" targetFramework="net40" /> <package id="Microsoft.Web.Infrastructure" version="1.0.0.0" targetFramework="net40" /> All the others target net451. Could this be the problem? Should I remove these packages? UPDATE 2 I tried to uninstall the Microsoft.Web.Infrastructure package (its description leads me to believe I don't need it; also, it has no dependencies) via the NuGet package manager, but it tells me, "NuGet failed to install or uninstall the selected package in the following project(s). [mine]" UPDATE 3 I went through the steps in again, and found that I had missed one step. I had to change this entry in the Application web.config File : <dependentAssembly> <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" /> <bindingRedirect oldVersion="1.0.0.0-5.0.0.0" newVersion="5.0.0.0" /> </dependentAssembly> (from "4.0.0.0" to "5.0.0.0") ...but I still get the same result - it rebuilds/compiles, but won't run, with "A project with an Output Type of Class Library cannot be started directly" UPDATE 4 Thinking about the err msg, that it can't directly open a class library, I thought, "Sure you can't/won't -- this is a web app, not a project. So I followed a hunch, closed the project, and reopened it as a website (instead of reopening a project). That has gotten me further, at least; now I see a YSOD: Could not load file or assembly 'System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified. UPDATE 5 Note: The project is now (after being opened as a web site) named "localhost_48614" And...there is no longer a "References" folder...?!?!? As to that YSOD I'm getting, the official instructions (http://www.asp.net/mvc/tutorials/mvc-5/how-to-upgrade-an-aspnet-mvc-4-and-web-api-project-to-aspnet-mvc-5-and-web-api-2) said to do this, and I quote: "Update all elements that contain “System.Web.WebPages.Razor” from version “2.0.0.0” to version“3.0.0.0”." UPDATE 6 When I select Tools Library Package Manager Manage NuGet Packages for Solution now, I get, "Operation failed. Unable to locate the solution directory. Please ensure that the solution has been saved." So I save it, and it saves it with this funky new name (C:\Users\clay\Documents\Visual Studio 2013\Projects\localhost_48614\localhost_48614.sln) I get the Yellow Strip of Enlightenment across the top of the NuGet Package Manager telling me, "Some NuGet packages are missing from this solution. Click to restore from your online package sources." I do (click the "Restore" button, that is), and it downloads the missing packages ... I end up with the 30 packages. I try to run the app/site again, and ... the erstwhile YSOD becomes a compilation error: The pre-application start initialization method Start on type System.Web.Mvc.PreApplicationStartCode threw an exception with the following error message: Could not load file or assembly 'System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.. Argghhhh!!! (and it's not even talk-like-a-pirate day).

• Socket in C: recv overwrite a char[]

  Hi all, I'm trying to make a little client-server script like many others that I've done in the past. But in this one I have a problem. It is better if I post the code and the output it give me.

Here's what the tables look like: mysql> select * from User; +----+-------+----------+ | id | name | password | +----+-------+----------+ | 1 | admin | admin | +----+-------+----------+ 1 row in set (0.00 sec) mysql> select * from Role; +----+----------------------+---------------+----------------+ | id | description | name | summary | +----+----------------------+---------------+----------------+ | 1 | administrator's role | administrator | Administration | | 2 | editor's role | editor | Editing | +----+----------------------+---------------+----------------+ 2 rows in set (0.00 sec) And here's the join table that was created: mysql> select * from User_Role; +---------+----------+ | User_id | roles_id | +---------+----------+ | 1 | 1 | | 1 | 2 | +---------+----------+ 2 rows in set (0.00 sec) And here's the subset of orm.xml that defines the tables and relationships: <entity class="User" name="User"> <table name="User" /> <attributes> <id name="id"> <generated-value strategy="AUTO" /> </id> <basic name="name"> <column name="name" length="100" unique="true" nullable="false"/> </basic> <basic name="password"> <column length="255" nullable="false" /> </basic> <one-to-many name="roles" fetch="EAGER" target-entity="Role" /> </attributes> </entity> <entity class="Role" name="Role"> <table name="Role" /> <attributes> <id name="id"> <generated-value strategy="AUTO"/> </id> <basic name="name"> <column name="name" length="40" unique="true" nullable="false"/> </basic> <basic name="summary"> <column name="summary" length="100" nullable="false"/> </basic> <basic name="description"> <column name="description" length="255"/> </basic> </attributes> </entity> Yet, despite that, when I retrieve the admin user, I get back an empty collection. I'm using Hibernate as my JPA provider and it shows the following debug SQL: select user0_.id as id8_, user0_.name as name8_, user0_.password as password8_ from User user0_ where user0_.name=? limit ? When the one-to-many mapping is lazy loaded, that's the only query that's made. This correctly retrieves the one admin user. I changed the relationship to use eager loading and then the following query is made in addition to the above: select roles0_.User_id as User1_1_, roles0_.roles_id as roles2_1_, role1_.id as id9_0_, role1_.description as descript2_9_0_, role1_.name as name9_0_, role1_.summary as summary9_0_ from User_Role roles0_ left outer join Role role1_ on roles0_.roles_id=role1_.id where roles0_.User_id=? Which results in the following results: +----------+-----------+--------+----------------------+---------------+----------------+ | User1_1_ | roles2_1_ | id9_0_ | descript2_9_0_ | name9_0_ | summary9_0_ | +----------+-----------+--------+----------------------+---------------+----------------+ | 1 | 1 | 1 | administrator's role | administrator | Administration | | 1 | 2 | 2 | editor's role | editor | Editing | +----------+-----------+--------+----------------------+---------------+----------------+ 2 rows in set (0.00 sec) Hibernate obviously knows about the roles, yet getRoles() still returns an empty collection. Hibernate also recognized the relationship sufficiently to put the data in the first place. What problems can cause these symptoms?

• Error using Session in IIS7

  - by flashnik

  After deployment of my website to IIS I'm getting a following error message when trying to access session: Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the \\ section in the application configuration. I access it in Page_Load or PreRender events (I tried both versions). With VS Dev Server it works without a problem. I tried both InProc an SessionState storage, 1 and multiple woker processes. I added a enableSessionState = "true" to my webpage explicitly.

• VBA nested Loop flow control

  - by PCGIZMO

  I will be brief and stick to what I know. This code for the most part works as it should. The only issue is in the iteration of the x and z loop. these to loops should set the range and yLABEL for the Y loop. I can get through a set and come up with the correct range after that things go bonkers. I know some of it has to do with not breaking out of x to set z and then back to x update the range. It should work z is found then x. the range between them is set for y. then next x but y stays then rang between y and x is set for y.. so on and so forth kinda like a slinky down the stairs. or a slide rule depending on how I set the loops either way I end up all over the place after a couple iterations. I have done a few things but each time I break out of x to set z , X restarts at the top of the range. At least that's what I think I am seeing. In the example sheet i have since changed the way the way the offset works with the loop but the idea is still the same. I have goto statements at this time i was going to try figuring out conditional switches after the loops were working. Any help direction or advice is appreciated.

• Openfire and LDAP issues

  - by clsmith

  Thanks in advance for the help. Has anyone see this issue with openfire? Currently I use Openfire Fedora with Auth using windows 2003 and also use mysql for the database. When I bring up two clients and talk to each other the time is slow between messages. Sometimes it can take between 5-15 minutes for something sent to get to the person (this is with only two people on the openfire server). I ran a tcp dump using port 389 and see that the machine is running thousands of queries against ldap. When i plug it into wireshark I notice that it is transferring the entire contact list or checking on the status of the entire contact list ? When I run debug on openfire itself I am presented with only this small message in the log: 2010.06.08 07:01:17 LdapManager: Starting LDAP search... 2010.06.08 07:01:17 LdapManager: ... search finished 2010.06.08 07:01:17 LdapManager: Creating a DirContext in LdapManager.getContext()... 2010.06.08 07:01:17 LdapManager: Created hashtable with context values, attempting to create context... 2010.06.08 07:01:17 LdapManager: ... context created successfully, returning. 2010.06.08 07:01:17 LdapManager: Trying to find a groups's DN based on it's groupname. cn: Spark agents CLT, Base DN: OU="Hidden",DC="Hidden",DC="net"... 2010.06.08 07:01:17 LdapManager: Creating a DirContext in LdapManager.getContext()... 2010.06.08 07:01:17 LdapManager: Created hashtable with context values, attempting to create context... 2010.06.08 07:01:17 LdapManager: ... context created successfully, returning. 2010.06.08 07:01:17 LdapManager: Starting LDAP search... 2010.06.08 07:01:17 LdapManager: ... search finished 2010.06.08 07:01:17 LdapManager: Trying to find a groups's DN based on it's groupname. cn: Spark agents CLT, Base DN: OU="Hidden",DC="Hidden",DC="net"... 2010.06.08 07:01:17 LdapManager: Creating a DirContext in LdapManager.getContext()... 2010.06.08 07:01:17 LdapManager: Created hashtable with context values, attempting to create context... 2010.06.08 07:01:17 LdapManager: ... context created successfully, returning. 2010.06.08 07:01:17 LdapManager: Starting LDAP search... 2010.06.08 07:01:17 LdapManager: ... search finished I thought this was a configuration on my end and started to look into the cache settings on the openfire webpages. I tweaked the settings as recommend by the pages and still get the same issues. I doesnt seem to cache the contact list or this might be a feature never fixed or implemented. Has anyone gone through this before ? I have searched online and I see others have great experience with openfire with no issues like I have, or is it because noone checked the queries ? For the time being I created a new Domain Controller and moved openfire to that computer so it can run local queries. This seems to help reduce the speed alot, but when I run the server performance manager tool I see that with two people only using that openfire server I run 593.7 request per second. Thanks for your help, if I didnt provide enough data please let me know what you need and I can find it.

• Why wont this JS code work if its all on the same line?

  - by culov

  I'm writing HTML code for a java servlet. i first write the code in html/js so i can debug what im working on, and then ill make it a java string and put it in my servlet. My problem is that the code is working fine when i view it in ff from a local html file, but when i view it on my java servlet, it doesnt work because the js isnt getting called. what I did was format the html that my servlet generated so that its not all on a single line and ran the code again. This time it worked. I copied this working code into a browser address bar so that it will all be on a single line, and copied that code back into the script in my html file. Now, when the previously working code is on a single line, it doesnt work. Here's the formatted JS: var sMax var holder; var preSet; var rated; var request; function rating(num){ sMax = 0; for(n=0; n<num.parentNode.childNodes.length; n++){ if(num.parentNode.childNodes[n].nodeName == "A"){ sMax++; } } if(!rated){ s = num.id.replace("_", ''); a = 0; for(i=1; i<=sMax; i++){ if(i<=s){ document.getElementById("_"+i).className = "on"; document.getElementById("rateStatus").innerHTML = num.title; holder = a+1; a++; }else{ document.getElementById("_"+i).className = ""; } } } } function off(me){ if(!rated){ if(!preSet){ for(i=1; i<=sMax; i++){ document.getElementById("_"+i).className = ""; document.getElementById("rateStatus").innerHTML = me.parentNode.title; } }else{ rating(preSet); document.getElementById("rateStatus").innerHTML = document.getElementById("ratingSaved").innerHTML; } } } function rateIt(me){ if(!rated){ document.getElementById("rateStatus").innerHTML = document.getElementById("ratingSaved").innerHTML + " "+me.title; preSet = me; rated=1; sendRate(me); rating(me); } } function sendRate(sel){ alert("Your rating was: "+sel.title); addRating("rating", "?truck=kogibbq?rating="+ sel.id); } function addRating(servletName, servletArguments){ var servlet = servletName; var arg = servletArguments var req = servlet + arg; alert(req); addrequest(req); request.onreadystatechange = function(){ alert("response received"); } } function addrequest(req) { try { request = new XMLHttpRequest(); }catch (e) { try { request = new ActiveXObject("Microsoft.XMLHTTP"); }catch (e) { alert("XMLHttpRequest error: " + e); } } request.open("GET", element, true); request.send(null); return request; } Thanks.

• Debugging EXC_BAD_ACCESS that occurs only on release target for an iPhone app?

  - by Bobby Moretti

  I'm developing an iPhone application. I have an EXC_BAD_ACCESS that occurs only in the release target; when I build the debug target the exception does not occur. However, when I set the NSZombieEnabled environment variable to YES, I still get the EXC_BAD_ACCESS with no further information. Is it even possible for NSZombieEnabled to work when executing the release target? I don't see why not, since gdb is running in both cases...

• Register NSService with Command Alt NSKeyEquivalent

  - by mahal tertin

  my Application provides a Global Service. I'd like to install the service with a command-alt-key combination. the thing i do now is not very error prone and really hard to debug as don't really see what's happening: inside Info.plist: <key>NSServices</key> <array> <dict> <key>NSSendTypes</key> <array> <string></string> </array> <key>NSReturnTypes</key> <array> <string></string> </array> <key>NSMenuItem</key> <dict> <key>default</key> <string>Go To Window in ${PRODUCT_NAME}</string> </dict> <key>NSMessage</key> <string>bringZFToForegroundZoomOut</string> <key>NSPortName</key> <string>com.raskinformac.${PRODUCT_NAME:identifier}</string> </dict> </array> and in the code: CFStringRef serviceStatusName = (CFStringRef)[NSString stringWithFormat:@"%@ - %@ - %@", appIdentifier, appName, methodNameForService]; CFStringRef serviceStatusRoot = CFSTR("NSServicesStatus"); CFPropertyListRef pbsAllServices = (CFPropertyListRef) CFMakeCollectable ( CFPreferencesCopyAppValue(serviceStatusRoot, CFSTR("pbs")) ); // the user did not configure any custom services BOOL otherServicesDefined = pbsAllServices != NULL; BOOL ourServiceDefined = NO; if ( otherServicesDefined ) { ourServiceDefined = NULL != CFDictionaryGetValue((CFDictionaryRef)pbsAllServices, serviceStatusName); } NSUpdateDynamicServices(); NSMutableDictionary *pbsAllServicesNew = nil; if (otherServicesDefined) { pbsAllServicesNew = [NSMutableDictionary dictionaryWithDictionary:(NSDictionary*)pbsAllServices]; } else { pbsAllServicesNew = [NSMutableDictionary dictionaryWithCapacity:1]; } NSDictionary *serviceStatus = [NSDictionary dictionaryWithObjectsAndKeys: (id)kCFBooleanTrue, @"enabled_context_menu", (id)kCFBooleanTrue, @"enabled_services_menu", @"@~r", @"key_equivalent", nil]; [pbsAllServicesNew setObject:serviceStatus forKey:(NSString*)serviceStatusName]; CFPreferencesSetAppValue ( serviceStatusRoot, (CFPropertyListRef) pbsAllServicesNew, CFSTR("pbs")); Boolean result = CFPreferencesAppSynchronize(CFSTR("pbs")); if (result) { NSUpdateDynamicServices(); JLog(@"successfully installed our alt-command-R service"); } else { ALog(@"couldn't install our alt-command-R service"); } and to change the service: // once installed, its's a bit tricky to set new ones (works only in RELEASE somehow?) // quit finder // open "~/Library/Preferences/pbs.plist" and remove ch.ana.Zoom - Reveal Window in Zoom - bringZFToForegroundZoomOut inside NSServicesStatus and save // start app // /System/Library/CoreServices/pbs -dump_pboard (to see if it hat actually done what we wanted, might be empty) // /System/Library/CoreServices/pbs (to add the new services) // /System/Library/CoreServices/pbs -dump_pboard (see new linking) // and then /System/Library/CoreServices/Finder.app/Contents/MacOS/Finder -NSDebugServices MY.APP.IDENTIFIER to restart finder so my question: is there a easier way to enable a Service with cmd-option-key? if yes, i'd gladly implement it in my software.

• How to deploy a visual studio custom tool?

  - by Aen Sidhe

  Hello. I have a my own custom tool for Visual Studio 2008 SP1. It consists of 5 assemblies: 3 assemblies with code that used heavily in my other projects, 1 assembly-wrapper above VS2008 SDK and assembly with the tool. If I'd debug my tool from visual studio, using "Run external program" option with command line "C:\Program Files (x86)\Microsoft Visual Studio 9.0\Common7\IDE\devenv.exe" and arguments "/ranu /rootsuffix Exp" all work perfectly. After that I trying to deploy it to my working VS copy, not to experimental hive doing: gacutil /i Asm1.dll for all my assemblies and doing RegAsm Asm1.dll only for assembly with custom tool. Neither of utils prints any error, all work as planned, even registry keys appeared. But my tool don't work even after PC restart. What did I do wrong?

• Why does this valid Tkinter code crash when mixed with a bit of PyWin32?

  - by Erlog

  So I'm making a very small program for personal use in tkinter, and I've run into a really strange wall. I'm mixing tkinter with the pywin32 bindings because I really hate everything to do with the syntax and naming conventions of pywin32, and it feels like tkinter gets more done with far less code. The strangeness is happening in the transition between the pywin32 clipboard watching and my program's reaction to it in tkinter. My window and all its controls are being handled in tkinter. The pywin32 bindings are doing clipboard watching and clipboard access when the clipboard changes. From what I've gathered about the way the clipboard watching pieces of pywin32 work, you can make it work with anything you want as long as you provide pywin32 with the hwnd value of your window. I'm doing that part, and it works when the program first starts. It just doesn't seem to work when the clipboard changes. When the program launches, it grabs the clipboard and puts it into the search box and edit box just fine. When the clipboard is modified, the event I want to fire off is firing off...except that event that totally worked before when the program launched is now causing a weird hang instead of doing what it's supposed to do. I can print the clipboard contents to stdout all I want if the clipboard changes, but not put that same data into a tkinter widget. It only hangs like that if it starts to interact with any of my tkinter widgets after being fired off by a clipboard change notification. It feels like there's some pywin32 etiquette I've missed in adapting the clipboard-watching sample code I was using over to my tkinter-using program. Tkinter apparently doesn't like to produce stack traces or error messages, and I can't really even begin to know what to look for trying to debug it with pdb. Here's the code: #coding: utf-8 #Clipboard watching cribbed from ## {{{ http://code.activestate.com/recipes/355593/ (r1) import pdb from Tkinter import * import win32clipboard import win32api import win32gui import win32con import win32clipboard def force_unicode(object, encoding="utf-8"): if isinstance(object, basestring) and not isinstance(object, unicode): object = unicode(object, encoding) return object class Application(Frame): def __init__(self, master=None): self.master = master Frame.__init__(self, master) self.pack() self.createWidgets() self.hwnd = self.winfo_id() self.nextWnd = None self.first = True self.oldWndProc = win32gui.SetWindowLong(self.hwnd, win32con.GWL_WNDPROC, self.MyWndProc) try: self.nextWnd = win32clipboard.SetClipboardViewer(self.hwnd) except win32api.error: if win32api.GetLastError () == 0: # information that there is no other window in chain pass else: raise self.update_search_box() self.word_search() def word_search(self): #pdb.set_trace() term = self.searchbox.get() self.resultsbox.insert(END, term) def update_search_box(self): clipboardtext = "" if win32clipboard.IsClipboardFormatAvailable(win32clipboard.CF_TEXT): win32clipboard.OpenClipboard() clipboardtext = win32clipboard.GetClipboardData() win32clipboard.CloseClipboard() if clipboardtext != "": self.searchbox.delete(0,END) clipboardtext = force_unicode(clipboardtext) self.searchbox.insert(0, clipboardtext) def createWidgets(self): self.button = Button(self) self.button["text"] = "Search" self.button["command"] = self.word_search self.searchbox = Entry(self) self.resultsbox = Text(self) #Pack everything down here for "easy" layout changes later self.searchbox.pack() self.button.pack() self.resultsbox.pack() def MyWndProc (self, hWnd, msg, wParam, lParam): if msg == win32con.WM_CHANGECBCHAIN: self.OnChangeCBChain(msg, wParam, lParam) elif msg == win32con.WM_DRAWCLIPBOARD: self.OnDrawClipboard(msg, wParam, lParam) # Restore the old WndProc.

• Why isn't my algorithm for find the biggest and smallest inputs working?

  - by Matt Ellen

  I have started a new job, and with it comes a new language: Ironpython. Thankfully a good language :D Before starting I got to grips with Python on the whole, but that was only a week's worth of learning. Now I'm writing actual code. I've been charged with writing an algorithm that finds the best input parameter to collect data with. The basic algorithm is (as I've been instructed): Set the input parameter to a good guess Start collecting data When data is available stop collecting find the highest point If the point before this (i.e. for the previous parameter value) was higher and the point before that was lower then we've found the max otherwise the input parameter is increased by the initial guess. goto 2 If the max is found then the min needs to be found. To do this the algorithm carries on increasing the input, but by 1/10 of the max, until the current point is greater than the previous point and the point before that is also greater. Once the min is found then the algorithm stops. Currently I have a simplified data generator outputting the sin of the input, so that I know that the min value should be PI and the max value should be PI/2 The main Python code looks like this (don't worry, this is just for my edification, I don't write real code like this): import sys sys.path.append(r"F:\Programming Source\C#\PythonHelp\PythonHelp\bin\Debug") import clr clr.AddReferenceToFile("PythonHelpClasses.dll") import PythonHelpClasses from PHCStruct import Helper from System import Math helper = Helper() def run(): b = PythonHelpClasses.Executor() a = PythonHelpClasses.HasAnEvent() b.Input = 0.0 helper.__init__() def AnEventHandler(e): b.Stop() h = helper h.lastLastVal, h.lastVal, h.currentVal = h.lastVal, h.currentVal, e.Number if h.lastLastVal < h.lastVal and h.currentVal < h.lastVal and h.NotPast90: h.NotPast90 = False h.bestInput = h.lastInput inputInc = 0.0 if h.NotPast90: inputInc = Math.PI/10.0 else: inputInc = h.bestInput/10.0 if h.lastLastVal > h.lastVal and h.currentVal > h.lastVal and h.NotPast180: h.NotPast180 = False if h.NotPast180: h.lastInput, b.Input = b.Input, b.Input + inputInc b.Start(a) else: print "Best input:", h.bestInput print "Last input:", h.lastInput b.Stop() a.AnEvent += AnEventHandler b.Start(a) PHCStruct.py: class Helper(): def __init__(self): self.currentVal = 0 self.lastVal = 0 self.lastLastVal = 0 self.NotPast90 = True self.NotPast180 = True self.bestInput = 0 self.lastInput = 0 PythonHelpClasses has two small classes I wrote in C# before I realised how to do it in Ironpython. Executor runs a delegate asynchronously while it's running member is true. The important code: public void Start(HasAnEvent hae) { running = true; RunDelegate r = new RunDelegate(hae.UpdateNumber); AsyncCallback ac = new AsyncCallback(UpdateDone); IAsyncResult ar = r.BeginInvoke(Input, ac, null); } public void Stop() { running = false; } public void UpdateDone(IAsyncResult ar) { RunDelegate r = (RunDelegate)((AsyncResult)ar).AsyncDelegate; r.EndInvoke(ar); if (running) { AsyncCallback ac = new AsyncCallback(UpdateDone); IAsyncResult ar2 = r.BeginInvoke(Input, ac, null); } } HasAnEvent has a function that generates the sin of its input and fires an event with that result as its argument. i.e.: public void UpdateNumber(double val) { AnEventArgs e = new AnEventArgs(Math.Sin(val)); System.Threading.Thread.Sleep(1000); if (null != AnEvent) { AnEvent(e); } } The sleep is in there just to slow things down a bit. The problem I am getting is that the algorithm is not coming up with the best input being PI/2 and the final input being PI, but I can't see why. Also the best and final inputs are different each time I run the programme. Can anyone see why? Also when the algorithm terminates the best and final inputs are printed to the screen multiple times, not just once. Can someone explain why?
