  • Help creating a ColumnName Convention using FluentNHibernate

    - by Rafael E. Belliard
    I've been trying to specify a custom naming convention for my database table columns. So far, I have been able to setup a convention for the table's name, but not the actual columns. I've seen a few guides on the internet, but they're not working using the latest Fluent NHibernate (1.0.0 RTM). public class CamelCaseSplitNamingConvention : IClassConvention, IComponentConvention { public void Apply(IClassInstance instance) { instance.Table(instance.EntityType.Name.ChangeCamelCaseToUnderscore()); } public void Apply(IComponentInstance instance) { // is this the correct call for columns? If not, which one? } } Please help.

  • 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?

  • How is includegraphic interfering with tabular?

    - by Charles Stewart
    I'm editing a text provided by my client as a LyX file that includes graphics and other files that I don't have. I've "commented out" the graphics by putting in a custom preamble that substitutes the file-loading definitions with macros that just quote their arguments. However, the \includegraphic macro throws up an error in the two tabular environments where it is used, complaining that \endfirsthead was never defined. What is this macro, and why is it interfering with mine? The preamble: \usepackage{natbib} \def\fileloc{/some/path/stylefile} \newif\iftextproof \IfFileExists\alifefileloc\textproofalse\textprooftrue \iftextproof \usepackage{./stylefile} %natbib subst: \renewcommand\cite[1]{{\tt #1}} %suppress graphics includes: \def\quotearg#1{\expandafter\string\csname #1\endcsname} \newcommand\gobbleIG[2][*void*]{{\footnotesize \quotearg{#2}}} \newcommand\gobbleSF[2][*unnamed*]{{\bf #1}} \let\includegraphics=\gobbleIG \let\subfigure=\gobbleSF \else \usepackage\fileloc \fi

  • 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?

  • 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?

  • 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

  • .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?

  • django handling file uploads - target different than media folder

    - by Tom Tom
    Hi, I want to enable the user to upload media which will not be saved in the media folder. When I use the following line of code data will be uploaded to media/upload/logo . logo_img = models.FileField(upload_to='upload/logo', blank=True) I'm wondering how I can change this behaviour. I would try to write a custom FileField and a view that serves the data based on the database entries. I do not want to place the data the user uploads to the media folder, since it is no public data. Is this approach correct? Are there solutions out there which do exactly what I want and I would reinvent the wheel with implementing this by myself? Would appreciate any help!

  • How can I dismiss keyboard in iPhone OS 3.2 with text field in popover?

    - by Tom H
    I have several text fields in a custom uiviewcontroller subclass, which is displayed within a popover. The popover is displayed form a bar button. I want the keyboard to go down when the popover is dismissed (either by the user tapping the bar button again, or tapping outside the popover. From the view controller that displays the popover, when the popover is dismissed, in either of the 2 fashions, I call [optionsController dismissFirstResponder]; Optionscontroller is the uiviewcontroller subclass in the popover. Dismissfirstresponder is a method I defined: -(void)dsimissFirstResponder { [nameField resignFirstResponder]; [descriptionField resignFirstResponder]; [helpField resignFirstResponder]; } Those are three IBoutlets which I connected in the xib to the text fields. That doesn't work. Any help with this would be greatly appreciated.

  • 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?

  • 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.

  • VS2008: Disable asking whether to reload files changed outside the IDE

    - by SealedSun
    Hi, I have a Visual Studio 2008 project where some code files are generated with each build (a parser, integrated via MSBuild aka editing the *.csproj file). VS does not know about the generated nature of these files (i.e. they are not the result of a "Custom Tool). So they "change" with every build, naturally. And VS2008 asks me after every build if I would like to reload those files: This file has been modified outside the source Do you want to reload it? That would be ok if I had one of those files opened and in front of me, but I get these modal dialogs even with none of the code files opened. So my question is: Is there a way to disable this dialog, per project, per solution or globally? Thanks!

  • Prevent Method call without Exception using @PreAuthorize Annotation

    - by Chepech
    Hi all. We are using Spring Security 3. We have a custom implementation of PermissionEvaluator that has this complex algorithm to grant or deny access at method level on the application. To do that we add a @PreAuthorize annotation to the method we want to protect (obviously). Everything is fine on that. However the behavior that we are looking for is that if a hasPermission call is denied, the protected method call only needs to be skipped, instead we are getting a 403 error each time that happens. Any ideas how to prevent that? You can find a different explanation of the problem here; AccessDeniedException handling during methodSecurityInterception

  • CakePHP: How do I order results based on a 2-level deep association model?

    - by KcYxA
    I'm hoping I won't need to resort to custom queries. A related question would be: how do I retrieve data so that if an associated model is empty, no record is retrieved at all, as opposed to an empty array for an associated model? As an oversimplified example, say I have the following models: City -- Street -- House How do I sort City results by House numbers? How do I retrieve City restuls that have at least one House in it? I don't want a record with a city name and details and an empty House array as it messes up pagination results. CakePHP retrieves House records belonging to the Street in a separate query, so putting somthing like 'House.number DESC' into the 'order' field of the search query returns a 'field does not exist' error. Any ideas?

  • iPhone: Save with validation on back navigation

    - by iPhone beginner
    In my iPhone application I have navigation controller, main screen and some edit screens. On edit screen user does some input that has to be validated before I can save it. Ideally I would like to update data automatically on back navigation without additional "Done" button. Can I do some validation and save on back navigation (i.e. when user taps on standard back button) in a way that allows my to stop navigation and show some error message if something is wrong? I see several other possibilities: Create my custom left button and make it looks like standard back. (Why Apple didn't put this button style into public API?) Add "Done" button and save data only if user taps it but both these choices I like much less. So if there is a way to achieve what I want, I'd like to use it.

  • Condition checking vs. Exception handling

    - by Aidas Bendoraitis
    When is exception handling more preferable than condition checking? There are many situations where I can choose using one or the other. For example, this is a summing function which uses a custom exception: # module mylibrary class WrongSummand(Exception): pass def sum_(a, b): """ returns the sum of two summands of the same type """ if type(a) != type(b): raise WrongSummand("given arguments are not of the same type") return a + b # module application using mylibrary from mylibrary import sum_, WrongSummand try: print sum_("A", 5) except WrongSummand: print "wrong arguments" And this is the same function, which avoids using exceptions # module mylibrary def sum_(a, b): """ returns the sum of two summands if they are both of the same type """ if type(a) == type(b): return a + b # module application using mylibrary from mylibrary import sum_ c = sum_("A", 5) if c is not None: print c else: print "wrong arguments" I think that using conditions is always more readable and manageable. Or am I wrong? What are the proper cases for defining APIs which raise exceptions and why?

  • How can I use the same buildscript for Flash Builder 4 and Ant/Mvn?

    - by David Laing
    I'm setting up a build system for a Flash Builder 4 (Flex 4) based project; and I'm struggling to get a setup that compiles in the IDE the same as it does from the command line on the build server. I come from a C# background; and my expectation is that I'll be able to create a "solution" with a collection of "projects" that I can compile from the IDE, or from the command line on the build server. The best I've managed sofar is 2 separate build "scripts", a custom ant script for the build server, and the default Flash Builder IDE config based on a workspace; but this is making my DRY daemons jump around in fury. Please can someone point me in the right direction :)

  • ItemsControl that loads items one by one asynchronously.

    - by Vinit Sankhe
    Hey Guys, I am creating a custom DataGrid by deriving the traditional tookit based WPF DataGrid. I want a functionality in the grid to load items one by one asynchronously, wherein as soon as ItemsSource is changed i.e. a new collection is Set to the ItemsSource property or the bound collection is Changed dues to items that rae added, moved or removed (wherein the notifications comes to the data grid when the underlying source implements INotifyCollectionChanged such as ObservableCollection). This is because even with virtualising stackpanel underneath the datagrid takes time to load (2-3 seconds delay) to load the data rows when it has several columns and some are template based. With above behavior that delay would "appear" to have reduced giving datagrid a feel that it has the data and is responsive enough to load it. How can I achieve it? Thx Vinit.

  • 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.

  • 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?

The error thrown is OutputStream is not available when a custom TextWriter is used.

  • 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!
