• .NET Framework 4 RC on Windows server 2008 R2

  - by mare

  I've just installed .NET 4 on Windows SErver 2008 R2 x64 and I am getting 500 Internal Server Error with an ASP.NET MVC application which was previously running fine on 3.5. The application was upgraded from targeting 3.5 to target 4 and I personally built it today on my development machine (changed in VS - Properties to .NET Framework 4). On the server I installed .NET Framework 4 Client profile RC for x86 and x64 platforms and I created a new .NET 4 application pool in IIS and placed the web app in it. Also I have custom errors turned Off in web.config but even so no detailed error is displayed - just the plain IIS 7.5 500 Internal Server Error. Any suggestions?

• Finding an open and closing tag in Regexp

  - by Rixius

  Is there a way to find custom tags in regexp I.e. match {a}sometext{/a} As well as {c=#fff}sometext{/c} So that it finds the entire block of inner content? The problem is the sometext could have another tag as in: {a=http://www.google.com}{b}Hello, world{/b}{/a} The only solutions I can come up with would match from {a... to .../b} when I want {a... to .../a} is there a single regexp solution, or would it be best to match the start, and then use another method to find the end from the back up, and grab it out that way? I'm using PHP 5.2 so I have all the options that entails.

• How do I manage report paging in HTML?

  - by ProfK

  I have a small, custom crafted HTML report, not using any reporting engine, for various reasons. The client's layout is quite handy, as each report section fits on its own page, so I have one div for each page, with a CSS class of .page, setting A4 dimensions with margin, and a header image. Each 'page' also has a small header table just under the header image, and a section heading label. Now, some sections threaten to overflow their page, and I'm looking at ways to handle this. One clumsy approach is to include a second page for those sections that might overflow, and delete these pages before rendering if they are empty. If I do this, how can I 'tell' content on one page to overflow into the next page? The report is finished and a once off effort, so I'm not keen to convert it into a SSRS or Telerik report just to achieve this paging.

• Change spring bean properties at configuration time

  - by Nick Gerakines

  In a spring servlet xml file, I'm using org.springframework.scheduling.quartz.SchedulerFactoryBean to regularly fire a set of triggers. <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean"> <property name="triggers"> <list> <ref local="AwesomeTrigger" /> <ref local="GreatTrigger" /> <ref local="FantasticTrigger"/> </list> </property> </bean> The issue is that in different environments, I don't want certain triggers firing. Is there a way to include some sort of configuration or variable defined either in my build.properties for the environment or in a spring custom context properties file that assists the bean xml to determine which triggers should be included in the list? That way, for example, AwesomeTrigger would be called in development but not qa.

• how to setup rails Authenticity Token to work with multiple domains?

  - by bwizzy

  I'm building an app that uses subdomains as account handles (myaccount.domain.com) and I have my sessions configured to work across the sub-domains like so: config.action_controller.session = {:domain => '.domain.com'} In addition to the subdomain a user can input a real domain name when they are creating their account. My Nginx config is setup to watch for *.com *.net etc, and this is working to serve out the pages. The problem comes when a site visitor submits a comment form on a custom domain that was input by the user. The code is throwing an "Invalid AuthenticityToken" exception. I'm 99% sure this is because the domain the user is on isn't specified as the domain in the config.action_controller.session. Thus the authenticity token isn't getting matched up because Rails can't find their session. So, the question is: Can you set config.action_controller.session to more than 1 domain, and if so can you add / remove from that value at runtime without restarting the app?

• How do I detect when a cell's value has changed in Silverlight?

  - by jvenema

  Hey folks, I'm working in Silverlight, trying to figure out how to set a grid cell font color based on the contents of the cell. I have an ObservableCollection bound to a DataGrid, and my items implement INotifyPropertyChanged so the grid updates as I change the values; it's all working perfectly, including letting me sort items and keep the sorting while I update the underlying items. I know I can use the LoadingRow event to change colors, but the only way I can get the event to fire is by changing the grids datasource, in which case my sorting goes out the window. So, what I really want is a way to either 1) loop the rows in the datagrid, find the cell I need, and change it's color or 2) implement a custom column that I can use to dynamically set the color. The problem is how to actually do either of those things :) All suggestions welcome.

• C# implicit conversions

  - by Chris Boden

  Hello, I'm currently working on an application where I need to load data from an SQL database and then assign the retrieved values into the properties of an object. I'm doing this by using reflection since the property names and column names are the same. However, many of the properties are using a custom struct type that is basically a currency wrapper for the decimal type. I have defined an implicit conversion in my struct: public static implicit operator Currency(decimal d) { return new Currency(d); } This works fine when I use it in code. However, when I have this: foreach (PropertyInfo p in props) { p.SetValue(this, table.Rows[0][p.Name], null); } It throws an ArgumentException stating that it cannot convert from System.Decimal to Currency. I'm confused since it works fine in any other circumstance.

• Meta Tags in Google Site Search

  - by ullmark

  Hi, I'm planning on implementing a google site search (and paying for it so I can get access to the XML). One thing I am wondering about is the possibility to use custom meta tags in it. I've heard yes from colleagues but nothing confirmed. Searching for an answer has given nothing (maybe because you cant?) Anybody knows? Edit: I want to be able to retrieve those meta tags from the search result to be able to provide different styling for different types of pages.

• ASP.NET: CSS friendly calendar control

  - by pbz

  I'm using the built-in Calendar control. It works, but in a few places the way the HTML is rendered is broken or not CSS-friendly and unfortunately cannot be changed (it's hard coded). I was hoping they would fix this in .NET 4.0, but as far as I can tell the Calendar control hasn't been changed at all. Also, as far as I know, there's no CSS adapter for the Calendar control. So, I would need a control that would: Allow me to customize the content of each cell (like OnDayRender works) Allow me to assign CSS classes to any HTML it may render Not render anything automatically that cannot be turned off, except layout code No auto-postback or auto-JS code (I can handle these by hand using simple links or custom JS calls) Basically a simple calendar view control that would give me full rendering control. What would you recommend? Thanks!

• Delphi: How to diagnose sluggish UI?

  - by Ian Boyd

  i have a form, which you can pretend is laid out like Windows Explorer: panel on the left splitter client panel +------------+#+-----------------------+ | |#| | | |#| | | |#| | | |#| | | Left |#| Client | | |#| | | |#| | | |#| | | |#| | | |#| | +------------+#+-----------------------+ ^ | +----splitter The the left and client area panels are each rich with controls. The problem is that using the splitter is very sluggish. i would expect that a modern 2 GHz computer can re-display the form as fast as a human can push the mouse around. But that's definitely not the case, and it takes about 200-300 ms before the form is fully re-adjusted. The form has about 100 visual controls on it, no code, or custom controls. How do i go about tracing who's the cause of the sluggishness?

• PayPal testing without using Sandbox

  - by Webbo

  I am developing a website in PHP that accepts PayPal payments. It uses the IPN from PayPal and has a custom payment template etc etc. It all works great through the Sandbox server but when it comes to showing my client, I don't want to have to tell them to login to/create a Sandbox account, create a buyer account and make a payment - he hasn't got time for that and probably won't be able to do it. Therefore, my question is - is there any simple way that I can show my client the PayPal integration in "test mode" without him using the sandbox? I realise that I can set the transaction value to 0.01 and just test on the live PayPal server but that isn't an ideal solution. Cheers! Edit: Just to better explain what I mean, this is what my client sees when he first goes to checkout; As you can see, he has to login to his Sandbox account before then purchasing the item using the buyer email that he sets up. It's just confusing and totally non user-friendly.

• RegEx to match a pattern and exclude a part of the string

  - by rojanu

  Hi, I have got some strings to be matched via RegEx. We have a java application which reads the regex from a config file and takes two groups of strings, number of which are specified in the same config. E.g. CustomAction.523274ca945f.dialogLabel=Executing Custom Code... will be matched with (?m)^(?!#)\s*(\S*)\s*=\s*(\S*.*) What I need is to pick the first group "CustomAction.523274ca945f.dialogLabel" and exclude the random string in the middle so I end up with something like "CustomAction.dialogLabel" or "CustomAction..dialogLabel" well any other combination but the random string. Thanks

• drupal bootstrap script: how to get list of all nodes of type x?

  - by groovehunter

  hi. I create a custom import and export, at the moment as an external script (via bootstrap), i plan to create a module in a more generic fashion lateron. I am building a frontend for nagios and for our host management and nagios configuration btw. Maybe it might become useful for other environments (networkmanagement) Now i need to know how to get list of all nodes of type x? I want to avoid direct SQL. A suggestion i got was to make an rss and parse it but i acess the drupal db a dozen times to extract various nodes, so it feels strange to do a web request for one thing So what i am looking for as newbie drupal dev is just a pointer to basic search module api for this task TIA florian

• Specifying different page base classes for different directories in your web.config file

  - by gbinflames

  I have a website (coded in vb.net) with an "admin" section (the admin section being a folder in the actual site)... So in every page of the site I'm using my own custom class as the page base (which has been set in the web.config file) but I want to inherit from different class for the files in the "admin" folder... Is there any way to inherit different classes for pages in different folders using the web.config or some other equally as global method? (meaning some other way than inheriting on a per page basis.)

• Accessing E4X nodes having special characters in name without breaking binding chain in flex.

  - by Jonas

  I am using E4X to bind some values from xml in flex 3. There is a problem when xml tag's (or attribute's) name has special character in it: having xml content var xml:XML = <tag> <special-name att="val" /> </tag> special-name could not be accessed using xml.special-name.@att because it is interpreted as subtraction, on the other hand using square bracket notation xml['special-name'].@att breaks binding chain. Is there an elegant way to solve this (like special language syntax) without writing custom binding setters and listeners?

• I get a 400 Bad Request error while using django-piston

  - by Cheezo

  Hello, I am trying to use Piston to provide REST support to Django. I have implemented my handlers as per the documentation provided . The problem is that i can "read" and "delete" my resource but i cannot "create" or "update". Each time i hit the relevant api i get a 400 Bad request Error. I have extended the Resource class for csrf by using this commonly available code snippet: class CsrfExemptResource(Resource): """A Custom Resource that is csrf exempt""" def init(self, handler, authentication=None): super(CsrfExemptResource, self).init(handler, authentication) self.csrf_exempt = getattr(self.handler, 'csrf_exempt', True) My class (code snippet) looks like this: user_resource = CsrfExemptResource(User) class User(BaseHandler): allowed_methods = ('GET', 'POST', 'PUT', 'DELETE') @require_extended def create(self, request): email = request.GET['email'] password = request.GET['password'] phoneNumber = request.GET['phoneNumber'] firstName = request.GET['firstName'] lastName = request.GET['lastName'] self.createNewUser(self, email,password,phoneNumber,firstName,lastName) return rc.CREATED Please let me know how can i get the create method to work using the POST operation?

• Is there a way to put Setter elements inside EventTrigger?

  - by Dennis Delimarsky

  Working on a WPF application, I started working on a custom ControlTemplate. I reached the point where I need to change some control properties when an event occurs. For this purpose, there are Setter elements. Seems all good, but I cannot use them inside EventTrigger elements. For example, if a simple Trigger, that can be bound to control properties, is used then Setter elements can be used inside. However, I do not want to bind to a property change but rather to an event. Is there a way to do this in pure XAML or will I have to work in the code-behind?

• Show only Parent Forums on bbPress front page

  - by Cameron

  I want to show only the very top level forums on my front page. I have tried: <?php if ( bb_forums("depth=1") ) : ?> But that didn't work and all the forums still show up. I only want to show the very top level, so for example if I have the following forums: Main - Sub Forum 1 - Sub Forum 2 --- Sub Forum 2.1 --- Sub Forum 2.1 - Sub Forum 3 Community - Sub Forum 1 - Sub Forum 2 --- Sub Forum 2.1 --- Sub Forum 2.1 - Sub Forum 3 Only Main and Community would appear on the home page. I would seem I need to create a custom loop on the front page that will only show the very top level forums, but I need some help. Thanks.

• Drawing text at an angle (e.g. upside down) in Android

  - by Damian

  I'm trying to build a custom clock view in Android. See image http://twitpic.com/1devk7 So far to draw the time and hour markers I have been using the Canvas.rotate method to get the desired effect. However, notice that it is difficult to interpret the numbers in the lower half of the clock (e.g. 6 or 9?) because of the angle in which they are drawn. When using drawText, is it possible to draw the text at 45/90/180 degrees so that all text appears upright when my onDraw method has finished?

• iPhone filesystem POSIX-compliant?

  - by Seva Alekseyev

  Hi all, I'm trying to pass some files from one app to another. I communicate the path (via a custom URL). The target application cannot read the file, citing errno 13 (permission denied). I've checked the permissions on file - they're 0644 (O+R), the permissions on directories all the way up to the root are 755 (O+RX). From a POSIX perspective, the file should be readable to any process and any user. Yet it's not. Any ideas, please? I can think of some workarounds. I could use a Web service (upload, get a cookie, communicate the cookie to the other app, other app downloads). I could also pass the actual file data in the URL - unelegant, and probably subject to length limitations. Clipboard is not supported on iPhone OS 2 IIRC.

• C# Getting Just Date From Timestamp

  - by Soo

  If I have a timestamp in the form: yyyy-mm-dd hh:mm:ss:mmm How can I just extract the date from the timestamp? For instance, if a timestamp reads: "2010-05-18 08:36:52:236" what is the best way to just get 2010-05-18 from it. What I'm trying to do is isolate the date portion of the timestamp, define a custom time for it to create a new time stamp. Is there a more efficient way to define the time of the timestamp without first taking out the date, and then adding a new time?
