• Using DPAPI / ProtectedData in a web farm environment with the User Store

  - by Lachman

  I was wondering if anyone had successfully used DPAPI with a user store in a web farm enviroment? Because our application is a recently converted from 1.1 to 2.0 asp.net app, we're using a custom wrapper which directly calls the CryptUnprotect methods. But this should be the same as the ProtectedData method available in the 2.0 framework. Because we are operating in a web farm environment, we can't guarantee that the machine that did the encryption is going to be the one decrypting it. (Also because machine failures shouldn't destroy our encrypted data). So what we have is a serviced component that runs in a service under a particular user account on each one of our web boxes. This user is a set up to have a roaming profile, as per the recomendation. The problem we have is that info encrypted on one machine can not be decrypted on another, this fails with the win32 error 'Key not valid for use in specified state'. I suspect that this is because I've made a mistake by having the encryption service running as the user on multiple machines, hence keeping the user logged in on more than one machine at the same time. If this is the problem, how are other using DPAPI with the User Store in a web farm environment?

• MVC 2 Data annotations problem

  - by Louzzzzzz

  Hi. Going mad now. I have a MVC solution that i've upgraded from MVC 1 to 2. It all works fine.... except the Validation! Here's some code: In the controller: using System; using System.Collections.Generic; using System.Globalization; using System.Linq; using System.Security.Principal; using System.Web; using System.Web.Mvc; using System.Web.Security; using System.Web.UI; using MF.Services.Authentication; using System.ComponentModel; using System.ComponentModel.DataAnnotations; namespace MF.Controllers { //basic viewmodel public class LogOnViewData { [Required] public string UserName { get; set; } [Required] public string Password { get; set; } } [HandleError] public class AccountController : Controller { [HttpPost] public ActionResult LogOn(LogOnViewData lvd, string returnUrl) { if (ModelState.IsValid) { //do stuff - IsValid is always true } } } } The ModelState is always valid. The model is being populated correctly however. Therefore, if I leave both username and password blank, and post the form the model state is still valid. Argh! Extra info: using structure map for IoD. Previously, before upgrading to MVC 2 was using the MS data annotation library so had this in my global.asax.cs: ModelBinders.Binders.DefaultBinder = new Microsoft.Web.Mvc.DataAnnotations.DataAnnotationsModelBinder(); Have removed that now. I'm sure i'm doing something really basic and wrong. If someone could point it out that would be marvellous. Cheers

• Comments not Getting Inserted into MySQL Table

  - by John

  Hello, I'm trying to use the code below for a comment system. It doesn't work. The info I'm trying to insert into the MySQL table "comment" isn't getting put there. Any idea(s) why it is not working? Thanks in advance, John On comments.php: echo '<form action="http://www...com/sandbox/comments/comments2.php" method="post"> <input type="hidden" value="'.$_SESSION['loginid'].'" name="uid"> <input type="hidden" value="'.$submissionid.'" name="submissionid"> <label class="addacomment" for="title">Add a comment:</label> <input class="commentsubfield" name="comment" type="title" id="comment" maxlength="1000"> <div class="commentsubbutton"><input name="submit" type="submit" value="Submit"></div> </form> '; On comments2.php: $comment = $_POST['comment']; $uid = $_POST['uid']; $subid = $_POST['submissionid']; mysql_query("INSERT INTO comment VALUES (NULL, '$uid', '$subid', '$comment', NULL, NULL)");

• Is it possible to have a SeekBar's thumb image extend outside the bar?

  - by Poko

  I have set negative paddings on my custom seekbar so that the round thumb image can go outside the bar, but the thumb isn't rendered out there, is there anyway to force the thumb to be drawn outside those bounds? Sorry guys, I'm new to Android development, and have been tasked with fixing an existing application. The problem is that we have a custom rounded looking track bar, which consists of two rounded 'end cap' images and a 1 px background that is tiled to create the seekbar. As far as I can tell there was never one image that could be set as the background of a normal SeekBar, which is why a custom one was created. The thumb is a circle and needs to 'fit' into the end caps - the three pieces of the bar are in a relative layout. Right now I'm kind of unclear as to how the 1 px background png gets stretched as the seekbar bg, otherwise I would try to tack on the two endcaps onto that drawable some how ... ? Please let me know if this was unclear and I'll try to post any followup info. Thanks in advance for any advice!! Oh, I'm using Android 2.1 if that's relevant to anyone's interests :)

• Clustering on WebLogic exception on Failover

  Hi all, I deploy an application on a WebLogic 10.3.2 cluster with two nodes, and a load balancer in front of the cluster.

• Apache rewrite rules redux

  - by AlexanderJohannesen

  I've got a REST framework that when plopped into any directory should Just Work(TM), and it seems to work fine when I've got projects in subdirectories, but not if it's in root. So, given a few example directories; / /project1 /bingo/project2 /hoopla/doopla/minor/project3 All of these works fine, except I'm getting "funnies"* when the project runs in the root directory (bit hard to explain, I suppose, but the second level rewrites are not working properly). Here's my attempt at a generic .htaccess file: RewriteEngine On RewriteRule ^static/ - [L] RewriteCond %{REQUEST_URI} ^$ RewriteRule .* ./ [R,L] RewriteRule ^index.php - [L] RewriteRule (.*) index.php?q=$1 [QSA,PT] (And yes, all projects have a subdirectory ./static which is ignored by rewrites) What I'm trying to achieve is a set of rewrite rules that work for most cases (which is, again, plonking the project in a directory the webserver serves). I'm not a rewrite rules wiz by a long shot, and any good advice and gotchas would be appreciated (and yes, I've gone through too many introductory articles. I need some serious juice.) More info on the funnies; my webserver has docroot in one spot (under /usr/share/apache2/default-site/), but a set of rules that says that /projects is pulled in from somewhere else that's not a subdirectory of docroot (/home/user/Projects/). When I go there, I get a list of /projects subdirectories, and if one of those subdirectories gets called (restmapp) with the proposed rewrite rules, I get ; The requested URL /home/user/Projects/restmapp/index.php was not found on this server.

• Removing a fields from a dynamic ModelForm

  - by Jérôme Pigeot

  In a ModelForm, i have to test user permissions to let them filling the right fields : It is defined like this: class TitleForm(ModelForm): def __init__(self, user, *args, **kwargs): super(TitleForm,self).__init__(*args, **kwargs) choices = [] # company if user.has_perm("myapp.perm_company"): self.fields['company'] = forms.ModelChoiceField(widget=forms.HiddenInput(), queryset=Company.objects.all(), required=False) choices.append('Company') # association if user.has_perm("myapp.perm_association") self.fields['association'] = forms.ModelChoiceField(widget=forms.HiddenInput(), queryset=Association.objects.all(), required=False) choices.append('Association') # choices self.fields['type_resource'] = forms.ChoiceField(choices = choices) class Meta: Model = Title This ModelForm does the work : i hide each field on the template and make them appearing thanks to javascript... The problem is this ModelForm is that each field defined in the model will be displayed on the template. I would like to remove them from the form if they are not needed: exemple : if the user has no right on the model Company, it won't be used it in the rendered form in the template. The problem of that is you have to put the list of fields in the Meta class of the form with fields or exclude attribute, but i don't know how to manage them dynamically. Any Idea?? Thanks by advance for any answer.

• How to route all subdomains to a single host using mDNS?

  - by John Mee

  I have a development webserver hosting as "myhost.local" which is found using Bonjour/mDNS. The server is running avahi-daemon. The webserver also wants to handle any subdomains of itself. Eg "cat.myhost.local" and "dog.myhost.local" and "guppy.myhost.local". Given that myhost.local is on a dynamic ip address from dhcp, is there still a way to route all requests for the subdomains to myhost.local? I'm starting to think it not currently possible... http://marc.info/?l=freedesktop-avahi&m=119561596630960&w=2 You can do this with the /etc/avahi/hosts file. Alternatively you can use avahi-publish-host-name. No, he cannot. Since he wants to define an alias, not a new hostname. I.e. he only wants to register an A RR, no reverse PTR RR. But if you stick something into /etc/avahi/hosts then it registers both, and detects a collision if the PTR RR is non-unique, which would be the case for an alias.

• Data Collection (Offline - no internet) and then syncing it to generate reports from server

  - by Nishant

  So, I have a new project I am planning on taking, and needed to know what skills will be required to achieve this project. The project is to do intensive data collection in the field where they don't have internet access. As part of the data collection, images will be uploaded as part of the data collection which will have to be resized, etc. Once the data collection occurs, this data needs to be consolidated and reported on. I am thinking there are two ways of generating the report. 1. Into a PDF that can be designed. 2. Is there a way to generate an executable file (since the PDF will be huge due to multiple images, etc) and the executable file is navigation friendly with drop-downs etc. It might not be an executable file, but could be a web page or some way that this can be delivered to the client in a friendly professional way. The PDF will have to be generated somehow so that it can be printed as a hard copy. What languages and skill sets will I need to accomplish this project?

• Correct escaping of delimited identifers in SQL Server without using QUOTENAME

  - by Ross Bradbury

  Is there anything else that the code must do to sanitize identifiers (table, view, column) other than to wrap them in double quotation marks and "double up" and double quotation marks present in the identifier name? References would be appreciated. I have inherited a code base that has a custom object-relational mapping (ORM) system. SQL cannot be written in the application but the ORM must still eventually generate the SQL to send to the SQL Server. All identifiers are quoted with double quotation marks. string QuoteName(string identifier) { return "\" + identifier.Replace("\"", "\"\"") + "\""; } If I were building this dynamic SQL in SQL, I would use the built-in SQL Server QUOTENAME function: declare @identifier nvarchar(128); set @identifier = N'Client"; DROP TABLE [dbo].Client; --'; declare @delimitedIdentifier nvarchar(258); set @delimitedIdentifier = QUOTENAME(@identifier, '"'); print @delimitedIdentifier; -- "Client""; DROP TABLE [dbo].Client; --" I have not found any definitive documentation about how to escape quoted identifiers in SQL Server. I have found Delimited Identifiers (Database Engine) and I also saw this stackoverflow question about sanitizing. If it were to have to call the QUOTENAME function just to quote the identifiers that is a lot of traffic to SQL Server that should not be needed. The ORM seems to be pretty well thought out with regards to SQL Injection. It is in C# and predates the nHibernate port and Entity Framework etc. All user input is sent using ADO.NET SqlParameter objects, it is just the identifier names that I am concerned about in this question. This needs to work on SQL Server 2005 and 2008.

• Beginning 3.2+ iPhone development

  - by Dinah

  I'm interested in learning Objective C for iPhone development. This is a topic which I realize has been covered to death. The qualifying difference is: I'd like to start learning beginning with the latest version (the most recent iPhone OS as of May, 2010 is ver. 3.2 and 4 beta is also out). I'd like to not have to wade through or unlearn legacy information. Using the links I've found throughout related topics on Stack Overflow, I'll read a blog post or tutorial which will say one thing, but then the comments will say, "this is different now in version xyz." For example, I've found this a few times regarding memory management/garbage collection. I assume that Apple's "getting started" doc.s will have the most recent info but many SO posts have said that those are not the most clear. The Stanford iPhone course looks great, but how do I know if it still applies to the most recent versions? Where should one start learning Objective C for iPhone development starting with version 3.2 or later without having as much exposure to legacy information?

• Should business objects be able to create their own DTOs?

  - by Sam

  Suppose I have the following class: class Camera { public Camera( double exposure, double brightness, double contrast, RegionOfInterest regionOfInterest) { this.exposure = exposure; this.brightness = brightness; this.contrast = contrast; this.regionOfInterest = regionOfInterest; } public void ConfigureAcquisitionFifo(IAcquisitionFifo acquisitionFifo) { // do stuff to the acquisition FIFO } readonly double exposure; readonly double brightness; readonly double contrast; readonly RegionOfInterest regionOfInterest; } ... and a DTO to transport the camera info across a service boundary (WCF), say, for viewing in a WinForms/WPF/Web app: using System.Runtime.Serialization; [DataContract] public class CameraData { [DataMember] public double Exposure { get; set; } [DataMember] public double Brightness { get; set; } [DataMember] public double Contrast { get; set; } [DataMember] public RegionOfInterestData RegionOfInterest { get; set; } } Now I can add a method to Camera to expose its data: class Camera { // blah blah public CameraData ToData() { var regionOfInterestData = regionOfInterest.ToData(); return new CameraData() { Exposure = exposure, Brightness = brightness, Contrast = contrast, RegionOfInterestData = regionOfInterestData }; } } or, I can create a method that requires a special IReporter to be passed in for the Camera to expose its data to. This removes the dependency on the Contracts layer (Camera no longer has to know about CameraData): class Camera { // beep beep I'm a jeep public void ExposeToReporter(IReporter reporter) { reporter.GetCameraInfo(exposure, brightness, contrast, regionOfInterest); } } So which should I do? I prefer the second, but it requires the IReporter to have a CameraData field (which gets changed by GetCameraInfo()), which feels weird. Also, if there is any even better solution, please share with me! I'm still an object-oriented newb.

• SVN checkout browser

  - by phazei

  I've been looking all over for a SVN browser. Now I'm not talking about anything like WebSVN or TRAC, I don't want to browse the repository; I want to browse the checkout. I'm looking for a program that lets me browse the checkout (working copy) and shows me the info I'd normally need to SSH for. So I could mark specific files or folders for some commit button, or see the status, or view a diff between the working and a prev version. Basically a web GUI for a svn checkout. A [windows] program that can let you work on a remote checkout as if it were local would also work. Currently I have a checkout on my server running under dev.mysite.com. I log in via ftp and edit and upload the files. I also keep SSH open so I can do a svn st to see what files I've worked on and to commit changes. I want to work on the files on the same environment so I can't simply use a local checkout. But I don't want to need to work via SSH. Are there any apps such as I described? Like a repo browser but for checkouts to do commits. Like WebTortoiseSVN or such. Thanks

• How to mmap the stack for the clone() system call on linux?

  - by Joseph Garvin

  The clone() system call on Linux takes a parameter pointing to the stack for the new created thread to use. The obvious way to do this is to simply malloc some space and pass that, but then you have to be sure you've malloc'd as much stack space as that thread will ever use (hard to predict). I remembered that when using pthreads I didn't have to do this, so I was curious what it did instead. I came across this site which explains, "The best solution, used by the Linux pthreads implementation, is to use mmap to allocate memory, with flags specifying a region of memory which is allocated as it is used. This way, memory is allocated for the stack as it is needed, and a segmentation violation will occur if the system is unable to allocate additional memory." The only context I've ever heard mmap used in is for mapping files into memory, and indeed reading the mmap man page it takes a file descriptor. How can this be used for allocating a stack of dynamic length to give to clone()? Is that site just crazy? ;) In either case, doesn't the kernel need to know how to find a free bunch of memory for a new stack anyway, since that's something it has to do all the time as the user launches new processes? Why does a stack pointer even need to be specified in the first place if the kernel can already figure this out?

The following code produces an error. $url = "http://dta-info/IVR/IVRINFO?WSDL"; $params = array("zANI" => "12345"); try{ $client = new SoapClient($url, array( 'trace' => 1, 'connection_timeout' => 2, 'location' => $url ) ); }catch(SoapFault $fault){ echo "faultstring: {$fault->faultstring})\n"; } try{ $result = $client->GetIVRinfo($params); }catch(SoapFault $fault){ echo "(faultcode: {$fault->faultcode}, faultstring: {$fault->faultstring} )\n"; } (faultcode: SOAP-ENV:Client, faultstring: There should be no path or parameters after a SOAP vname. ) So i tried to use a non-wsdl mode but i receive a different error no matter how i try to format the params. $url = "http://dta-info/IVR/IVRINFO"; $params = array("zANI" => "12345"); try{ $client = new SoapClient(null, array( 'trace' => 1, 'connection_timeout' => 2, 'location' => $url, 'uri' => $uri, 'style' => SOAP_DOCUMENT, 'use' => SOAP_LITERAL, 'soap_version' => SOAP_2 ) ); }catch(SoapFault $fault){ echo "faultstring: {$fault->faultstring})\n"; } try{ $result = $client->GetIVRinfo($params); }catch(SoapFault $fault){ echo "(faultcode: {$fault->faultcode}, faultstring: {$fault->faultstring} )\n"; } (faultcode: SOAP-ENV:Client, faultstring: The method element needs to belong to the namespace 'http://GETIVRINFO/IVR/IVRINFO'. ) I have tested this WSDL with a tool called SoapUI and it returns the results with no errors. So it leads me to believe I'm not formatting the vars or headers correctly with PHP. I also tried passing in a xml fragment as the param but that returns the same error. What am i doing wrong?????? $params = '<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ivr="http://GETIVRINFO/IVR/IVRINFO"> <soapenv:Header/> <soapenv:Body> <ivr:GetIVRinfo> <!--Optional:--> <ivr:zANI>12345</ivr:zANI> </ivr:GetIVRinfo> </soapenv:Body> </soapenv:Envelope>'; Here is the WSDL document: <?xml version="1.0"?><wsdl:definitions name="IVR"

• Defining jUnit Test cases Correctly

  - by Epitaph

  I am new to Unit Testing and therefore wanted to do some practical exercise to get familiar with the jUnit framework. I created a program that implements a String multiplier public String multiply(String number1, String number2) In order to test the multiplier method, I created a test suite consisting of the following test cases (with all the needed integer parsing, etc) @Test public class MultiplierTest { Multiplier multiplier = new Multiplier(); // Test for 2 positive integers assertEquals("Result", 5, multiplier.multiply("5", "1")); // Test for 1 positive integer and 0 assertEquals("Result", 0, multiplier.multiply("5", "0")); // Test for 1 positive and 1 negative integer assertEquals("Result", -1, multiplier.multiply("-1", "1")); // Test for 2 negative integers assertEquals("Result", 10, multiplier.multiply("-5", "-2")); // Test for 1 positive integer and 1 non number assertEquals("Result", , multiplier.multiply("x", "1")); // Test for 1 positive integer and 1 empty field assertEquals("Result", , multiplier.multiply("5", "")); // Test for 2 empty fields assertEquals("Result", , multiplier.multiply("", "")); In a similar fashion, I can create test cases involving boundary cases (considering numbers are int values) or even imaginary values. 1) But, what should be the expected value for the last 3 test cases above? (a special number indicating error?) 2) What additional test cases did I miss? 3) Is assertEquals() method enough for testing the multiplier method or do I need other methods like assertTrue(), assertFalse(), assertSame() etc 4) Is this the RIGHT way to go about developing test cases? How am I "exactly" benefiting from this exercise? 5)What should be the ideal way to test the multiplier method? I am pretty clueless here. If anyone can help answer these queries I'd greatly appreciate it. Thank you.

• Taking the data mapper approach in Zend Framework

  - by Seeker

  Let's assume the following tables setup for a Zend Framework app. user (id) groups (id) groups_users (id, user_id, group_id, join_date) I took the Data Mapper approach to models which basically gives me: Model_User, Model_UsersMapper, Model_DbTable_Users Model_Group, Model_GroupsMapper, Model_DbTable_Groups Model_GroupUser, Model_GroupsUsersMapper, Model_DbTable_GroupsUsers (for holding the relationships which can be seen as aentities; notice the "join_date" property) I'm defining the _referenceMap in Model_DbTable_GroupsUsers: protected $_referenceMap = array ( 'User' => array ( 'columns' => array('user_id'), 'refTableClass' => 'Model_DbTable_Users', 'refColumns' => array('id') ), 'App' => array ( 'columns' => array('group_id'), 'refTableClass' => 'Model_DbTable_Groups', 'refColumns' => array('id') ) ); I'm having these design problems in mind: 1) The Model_Group only mirrors the fields in the groups table. How can I return a collection of groups a user is a member of and also the date the user joined that group for every group? If I just added the property to the domain object, then I'd have to let the group mapper know about it, wouldn't I? 2) Let's say I need to fetch the groups a user belongs to. Where should I put this logic? Model_UsersMapper or Model_GroupsUsersMapper? I also want to make use of the referencing map (dependent tables) mechanism and probably use findManyToManyRowset or findDependentRowset, something like: $result = $this->getDbTable()->find($userId); $row = $result->current(); $groups = $row->findManyToManyRowset( 'Model_DbTable_Groups', 'Model_DbTable_GroupsUsers' ); This would produce two queries when I could have just written it in a single query. I will place this in the Model_GroupsUsersMapper class. An enhancement would be to add a getGroups method to the Model_User domain object which lazily loads the groups when needed by calling the appropriate method in the data mapper, which begs for the second question. Should I allow the domain object know about the data mapper?

• Regex with optional part doesn't create backreference

  - by padraigf

  I want to match an optional tag at the end of a line of text. Example input text: The quick brown fox jumps over the lazy dog {tag} I want to match the part in curly-braces and create a back-reference to it. My regex looks like this: ^.*(\{\w+\})? (somewhat simplified, I'm also matching parts before the tag): It matches the lines ok (with and without the tag) but doesn't create a back-reference to the tag. If I remove the '?' character, so regex is: ^.*(\{\w+\}) It creates a back-reference to the tag but then doesn't match lines without the tag. I understood from http://www.regular-expressions.info/refadv.html that the optional operator wouldn't affect the backreference: Round brackets group the regex between them. They capture the text matched by the regex inside them that can be reused in a backreference, and they allow you to apply regex operators to the entire grouped regex. but must've misunderstood something. How do I make the tag part optional and create a back-reference when it exists?

  Hello, I have a situation where i have a listbox of comboboxes , mainly it binds to a bridge entity so the object contains foreign keys . What i need to do is that i need to bind the display of the combos to the respective entities and their value members to the foreign key values in the bridge entity that i bind the listbox to. the code i have now is : <ListBox Name="lstServices" ScrollViewer.HorizontalScrollBarVisibility="Disabled" HorizontalContentAlignment="Stretch"> <ListBox.ItemTemplate> <DataTemplate> <Grid Margin="2" DataContext="{Binding ElementName=wndMain,Path=DataContext}"> <Grid.ColumnDefinitions> <ColumnDefinition Width="*"/> <ColumnDefinition Width="*"/> </Grid.ColumnDefinitions> <ComboBox Name="cmbService" SelectedIndex="0" DisplayMemberPath="Name" SelectedValuePath="{Binding RelativeSource={RelativeSource Mode=TemplatedParent}, Path=FK_ServiceID}" ItemsSource="{Binding Path=AllServices}" Grid.Column="0"></ComboBox> <ComboBox Name="cmbService_Role" Margin="2,0,0,0" SelectedValuePath="{Binding Path=FK_ServiceRoleID}" DisplayMemberPath="Name" ItemsSource="{Binding Path=AllService_Roles}" Grid.Column="1"></ComboBox> </Grid> </DataTemplate> </ListBox.ItemTemplate> </ListBox> I could manage to display the values that i needed but since the List Item context changed i can't get to the listbox itemSource .

• How do I use a dependency on a Perl module installed in a non-standard location?

  - by Kinopiko

  I need to install two Perl modules on a web host. Let's call them A::B and X::Y. X::Y depends on A::B (needs A::B to run). Both of them use Module::Install. I have successfully installed A::B into a non-system location using perl Makefile.PL PREFIX=/non/system/location make; make test; make install Now I want to install X::Y, so I try the same thing perl Makefile.PL PREFIX=/non/system/location The output is $ perl Makefile.PL PREFIX=/non/system/location/ Cannot determine perl version info from lib/X/Y.pm *** Module::AutoInstall version 1.03 *** Checking for Perl dependencies... [Core Features] - Test::More ...loaded. (0.94) - ExtUtils::MakeMaker ...loaded. (6.54 >= 6.11) - File::ShareDir ...loaded. (1.00) - A::B ...missing. ==> Auto-install the 1 mandatory module(s) from CPAN? [y] It can't seem to find A::B in the system, although it is installed, and when it tries to auto-install the module from CPAN, it tries to write it into the system directory (ignoring PREFIX). I have tried using variables like PERL_LIB and LIB on the command line, after PREFIX=..., but nothing I have done seems to work. I can do make and make install successfully, but I can't do make test because of this problem. Any suggestions? I found some advice at http://servers.digitaldaze.com/extensions/perl/modules.html to use an environment variable PERL5LIB, but this also doesn't seem to work: export PERL5LIB=/non/system/location/lib/perl5/ didn't solve the problem.

• PHP XML Strategy: Parsing DOM to fill "Bean"

  - by Mike

  I have a question concerning a good strategy on how to fill a data "bean" with data inside an xml file. The bean might look like this: class Person { var $id; var $forename = ""; var $surname = ""; var $bio = new Biography(); } class Biography { var $url = ""; var $id; } the xml subtree containing the info might look like this: <root> <!-- some more parent elements before node(s) of interest --> <person> <name pre="forename"> Foo </name> <name pre="surname"> Bar </name> <id> 1254 </id> <biography> <url> http://www.someurl.com </url> <id> 5488 </id> </biography> </person> </root> At the moment, I have one approach using DOMDocument. A method iterates over the entries and fills the bean by "remembering" the last node. I think thats not a good approach. What I have in mind is something like preconstructing some xpath expression(s) and then iterate over the subtrees/nodeLists. Return an array containing the beans as defined above eventually. However, it seems not to be possible reusing a subtree /DOMNode as DOMXPath constructor parameter. Has anyone of you encountered such a problem?

• decimal.TryParse() drops leading "1"

  - by Martin Harris

  Short and sweet version: On one machine out of around a hundred test machines decimal.TryParse() is converting "1.01" to 0.01 Okay, this is going to sound crazy but bare with me... We have a client applications that communicates with a webservice through JSON, and that service returns a decimal value as a string so we store it as a string in our model object: [DataMember(Name = "value")] public string Value { get; set; } When we display that value on screen it is formatted to a specific number of decimal places. So the process we use is string - decimal then decimal - string. The application is currently undergoing final testing and is running on more than 100 machines, where this all works fine. However on one machine if the decimal value has a leading '1' then it is replaced by a zero. I added simple logging to the code so it looks like this: Log("Original string value: {0}", value); decimal val; if (decimal.TryParse(value, out val)) { Log("Parsed decimal value: {0}", val); string output = val.ToString(format, CultureInfo.InvariantCulture.NumberFormat); Log("Formatted string value: {0}", output); return output; } On my machine - any every other client machine - the logfile output is: Original string value: 1.010000 Parsed decimal value: 1.010000 Formatted string value: 1.01 On the defective machine the output is: Original string value: 1.010000 Parsed decimal value: 0.010000 Formatted string value: 0.01 So it would appear that the decimal.TryParse method is at fault. Things we've tried: Uninstalling and reinstalling the client application Uninstalling and reinstalling .net 3.5 sp1 Comparing the defective machine's regional settings for numbers (using English (United Kingdom)) to those of a working machine - no differences. Has anyone seen anything like this or has any suggestions? I'm quickly running out of ideas... While I was typing this some more info came in: Passing a string value of "10000" to Convert.ToInt32() returns 0, so that also seems to drop the leading 1.

• pylons on production server fedora 8

  - by stormdrain

  I'm interested in learning some python, and thought Pylons would be a good starting point (after spending 2 days trying to get django working -- to no avail). I have an Amazon EC2 instance with Fedora 8 on it. It is a bare-bones install. I am halfway through my second day of trying to get it to work. I have mod_wsgi installed. I have Apache (though that's a later task to tackle). I have easy_install, paster is working fine; basically all of the pre-requisites mentioned throughout the Pylons docs. I can't for the life of me get the thing to work. And I can't seem to find a coherent walkthough anywhere that lists all the steps necessary. There is tons of info out there, but it is all scattered. Wsgi this, python that. Google, google, google... "47 million results found for 'socket.error:(lol, 'Yous a goofs')". So, this is my latest attempt: apachectl -k stop cd /home/ paster create -t pylons test [blah blah.. ok] cd test nano development.ini [hmm, last time I changed the host from 127.0.0.1 to my domain name or url, it threw an error like socket.error: (99, 'Cannot assign requested address')... I'll just leave it] [open port 5000 on firewall] paster serve development.ini [firefox-url:5000] Firefox can't establish a connection to the server Doing these steps locally works as expected. This is just a test to see if I can get it to work at all, which I can't. If I get it to work, then is the task of getting it to work with apache. My madness is that I'd like to play around a little developing and deploying before diving into a full-fledged project. So far: self, I am dissapoint.

• Git with SSH on Windows

  - by pankar

  Hello all, I've went through the excellent guide provided by Tim Davis (http://www.timdavis.com.au/git/setting-up-a-msysgit-server-with-copssh-on-windows/) which is about configuring Git to work with SSH under Windows in order to produce a Git Server in order to have a main place for my DVCS. I am in the process of creating a clone for my project. I’ve went through all the steps till this point, but I keep getting this from TortoiseGit: git.exe clone -v “ssh://[email protected]:22/SSH/Home/administrator/myapp.git” “E:\GitTest\myapp” bash: [email protected]: command not found Initialized empty Git repository in E:/GitTest/myapp/.git/ fatal: The remote end hung up unexpectedly Success and nothing gets cloned. BTW: The TortoisePLink comes up just before this message appears and asks me: “login as:” ( I thought that this info is given in the command, i.e: Administrator@blahblah. My home variable is set to the correct place: From a Git Bash shell: echo $HOME /c/SSH/home/Administrator I’ve also tried using Putty’s plink instead of TortoisePLink (in both Git’s and TortoiseGit’s installation). This time the error was narrowed down to: git.exe clone -v “ssh://[email protected]:22/c:/SSH/Home/administrator/myapp.git” “E:\GitTest\myapp” Initialized empty Git repository in E:/GitTest/myapp/.git/ fatal: The remote end hung up unexpectedly Any help is more than welcome!
