  • Using ADO.NET Entities LINQ Provider to model complex SQL Queries?

    - by Ivan Zlatanov
    What I find really powerful in ADO.NET Entities or LINQ to SQL, is the ability to model complex queries. I really don't need the mappings that Entities or LINQ to SQL are doing for me - I just need the ability to model complex expressions that can be translated into T-SQL. My question is - am I abusing too much? Can I use the Entity Framework for modeling queries and just that? Should I? I know I can write my own custom LINQ to SQL provider, but that is just not possible to handle in the time spans I have. What is the best approach to model complex T-SQL queries? How do you handle conditional group byes, orders, joins, unions etc in the OOP world? Using StringBuilders for this kind of job feels too ugly and harder to maintain given the possibilities we have with Expression Trees. When I use StringBuilder to model a complex SQL Query I feel kind of guilty! I feel the same way as when I have to hard code any number into my code that is different than 0 or 1. Feeling that makes you ask yourself if there is a better and cleaner way of doing it... I must mention that I am using C# 4.0, but I am not specifically looking for an answer in this language, but rather in the domain of CLR 4.

  • Drawing graphics on top of a JButton

    - by trinth
    I have a situation wherein I have a bunch of JButtons on a GridLayout. I need each of the JButtons to have: a background image (but retain the ability to keep the default button look if needed) custom graphics drawn on top by other classes I have no trouble with the background image, since I am using setIcon() but I am having problems drawing things on top of the background. At one point I was able to draw on top of the button, but after the button was clicked, the drawings disappeared. How can make the button keep this drawing state? Basically, I need a way for my JButtons to have public methods that would allow another class to draw anything on it such as: public void drawSomething() { Graphics g = this.getGraphics(); g.drawOval(3,2,2,2); repaint(); } or public Graphics getGraphics() { return this.getGraphics(); } then another class could do this: button.getGraphics().drawSomething(); The latter is more what I am looking for but the first is equally useful. Is there any way to go about this? Also, overriding the parent class method paintComponent() doesn't help since I need each button to have different graphics.

  • Wordpress/CSS: List Style Problem.

    - by Ben
    Hi all! I am reasonably new to Wordpress custom themes but I do have some knowlege of CSS, although I am terrible at customising other peoples code which is why I have the problem I am about to explain. I have started a website that my girlfriend and I are doing together. It uses the Simplo Wordpress theme which is pretty cool but when you add a post that has a list in it. It doesn't show the bullets on each of the items. I have tried adding 'list-style:circle;' to a the.postItem class and a couple of other divs and classes that I thought were relevant but it doesn't work. You can take a look for yourself, it may be easier to understand my problem that way. If you go to: http://brokeandstarving.com/234/bennos-shepherds-pie/ there is a list of ingredients and also the steps under the method is a list as well. My question is, where do I edit the CSS to make the bullets appear next to the list items? I hope that makes sense. Thanks in advance, - Ben

  • Problem: How to display a Wordpress RSS feed in a browser that doesn't have a built in RSS reader?

    - by StephenMeehan
    If I can, i'd rather not use a service like FeedBurner. My setup: I've setup a RSS feed link on a self-hosted Wordpress website, clicking the RSS link in Safari shows the feed - because Safari has a built in RSS reader. Great. Unfortunately clicking the same RSS link in Chrome displays the raw XML feed. I know why this happens - Chrome doesn't have a built in RSS reader. I also assume this will be the same in older versions of Internet Explorer. Possible solution? I've noticed http://www.bbc.co.uk/news has a nice solution: Click the RSS feed (top tight of the page) in a RSS enabled browser (Safari) and it uses the built in RSS reader to display the RSS feed. Click the same RSS feed link in Chrome (Chrome has no built in RSS reader) it displays the RSS feed using what looks like a custom page. Is there a way to check if a browser has a built in RSS reader? How would I provide alternative content (like the BBC site) to a browser that doesn't have a RSS reader installed? Any help on this would be brilliant, thanks for taking the time to read this. Stephen

  • How can i use a commandlinetool (ie. sox) via subprocess.Popen with mod_wsgi?

    - by marue
    I have a custom django filefield that makes use of sox, a commandline audiotool. This works pretty well as long as i use the django development server. But as soon as i switch to the production server, using apache2 and mod_wsgi, mod_wsgi catches every output to stdout. This makes it impossible to use the commandline tool to evaluate the file, for example use it to check if the uploaded file really is an audio file like this: filetype=subprocess.Popen([sox,'--i','-t','%s'%self.path], shell=False,\ stdout=subprocess.PIPE, stderr=subprocess.PIPE) (filetype,error)=filetype.communicate() if error: raise EnvironmentError((1,'AudioFile error while determining audioformat: %s'%error)) Is there a way to workaround for this? edit the error i get is "missing filename". I am using mod_wsgi 2.5, standard with ubuntu 8.04. edit2 What exactly happens, when i call subprocess.Popen from within django in mod_wsgi? Shouldn't subprocess stdin/stdout be independent from django stdin/stdout? In that case mod_wsgi should not affect programms called via subprocess... I'm really confused right now, because the file i am trying to access is a temporary file, created via a filenamevariable that i pass to the file creation and the subprocess command. That file is being written to /tmp, where the rights are 777, so it can't be a rights issue. And the error message is not "file does not exist", but "missing filename", which suggests i am not passing a filename as parameter to the commandlinetool.

  • Do you have health checks in your web app or web site?

    - by Pekka
    I have built PHP based "health check" scripts for several projects, but they were always custom-made for the occasion and not written for abstraction as an independent product. I would like to know whether such a solution exists. What I meam by "health check" is a protected web page that functions much like a suite of unit tests, but on a more operational level, showing red/yellow/green statuses for things like Are the cache directories writable? Is the PHP version correct, are required extensions installed? Is the configuration file protected from writing? Is the database server reachable? Do the key tables exist in the database? Is there enough disk space available? Is the site's front page reachable and renders fully ( = no PHP errors)? Do the project's libraries' MD5 checksums match the original ones? Do you do this - or parts of it - in your applications and web sites? Are there any standardized tools for this that bring along all the functionality to perform the tests (ideally as plugins), and just need to be configured accordingly? Is there a way to set this up using one of the Unit Testing frameworks available for PHP (preferably PHPUnit)? If so, do you know any resources / tutorials outlining how?

  • How to use the `itemDoubleClicked(QTreeWidgetItem*,int)` signal in qtHaskell

    - by nano
    I want to use the itemDoubleClicked(QTreeWidgetItem*,int) signal in a Haskell program I'm writing where I am using qtHaskell for the GUI. To connect a function I have at other places done the following: dummyWidget <- myQWidget connectSlot object signal dummyWidget "customSlot()" $ f Where object is some QWidget and signal is a string giving the signal, e.g. "triggered()", and f is the function I want to be called when the signaled is send. The definition of connectSlot in the API is: class Qcs x where connectSlot :: QObject a -> String -> QObject b -> String -> x -> IO () where the instances ofQcs are: Qcs () Qcs (QObject c -> String -> IO ()) Qcs (QObject c -> Object d -> IO ()) Qcs (QObject c -> Bool -> IO ()) Qcs (QObject c -> Int -> IO ()) Qcs (QObject c -> IO ()) Qcs (QObject c -> OpenGLVersionFlag -> IO ()) The first Arguments passed is supposed to be the QObject of which I'm using a signal. As you can see, there is no instance where f, the function to connect to the signal, can have two further arguments to recieve the QWidget and the integer send by the signal. Is there a way to nevertheless connect that signal to a custom function?

  • Gridview Paging via ObjectDataSource: Why is maximumRows being set to -1?

    - by Bryan
    So before I tried custom gridview paging via ObjectDataSource... I think I read every tutorial known to man just to be sure I got it. It didn't look like rocket science. I've set the AllowPaging = True on my gridview. I've specified PageSize="10" on my gridview. I've set EnablePaging="True" on the ObjectDataSource. I've added the 2 paging parms (maximumRows & startRowIndex) to my business object's select method. I've created an analogous "count" method with the same signature as the select method. The only problem I seem to have is during execution... the ObjectDataSource is supplying my business object with a maximumRows value of -1 and I can't for the life of me figure out why. I've searched to the end of the web for anyone else having this problem and apparently I'm the only one. The StartRowIndex parameter seems to be working just fine. Any ideas?

  • SQL-Server: Is there an equivalent of a trigger for general stored procedure execution

    - by Arj
    Hi All, Hope you can help. Is there a way to reliably detect when a stored proc is being run on SQL Server without altering the SP itself? Here's the requirement. We need to track users running reports from our enterprise data warehouse as the core product we use doesn't allow for this. Both core product reports and a slew of in-house ones we've added all return their data from individual stored procs. We don't have a practical way of altering the parts of the product webpages where reports are called from. We also can't change the stored procs for the core product reports. (It would be trivial to add a logging line to the start/end of each of our inhouse ones). What I'm trying to find therefore, is whether there's a way in SQL Server (2005 / 2008) to execute a logging stored proc whenever any other stored procedure runs, without altering those stored procedures themselves. We have general control over the SQL Server instance itself as it's local, we just don't want to change the product stored procs themselves. Any one have any ideas? Is there a kind of "stored proc executing trigger"? Is there an event model for SQL Server that we can hook custom .Net code into? (Just to discount it from the start, we want to try and make a change to SQL Server rather than get into capturing the report being run from the products webpages etc) Thoughts appreciated Thanks

  • Advance: Parsing XML into another XML page using only javascript or jquery; Can't use PhP, Java or MySQL

    - by UrBestFriend
    Current site: http://cardwall.tk/ Example of intended outcome: http://www.shockwave.com/downloadWall.jsp I have an embeded flash object that uses XML/RSS (Picasa) to feed itself pictures. Now I created my own XML/RSS feed so that I can add additional XML tags and values. Now here's my big problem: enabling search. Since I'm not relying on Picasa's API anymore to return custom RSS/XML for the user's search, how can I create xml from another xml based on the user's search queries using only JavaScript and Jquery? Here is the current code: <script type="text/javascript"> var flashvars = { feed : "http%3A%2F%2Frssfeed.ucoz.com%2Frssfeed.xml", backgroundColor : "#FFFFFF", metadataFont : "Arial", wmode : "opaque", iFrameScrolling: "no", numRows : "3", }; var params = { allowFullScreen: "true", allowscriptaccess : "always", wmode: "opaque" }; swfobject.embedSWF("http://apps.cooliris.com/embed/cooliris.swf", "gamewall", "810", "410", "9.0.0", "", flashvars, params); $(document).ready(function() { $("#cooliris input").keydown(function(e) { if(e.keyCode == 13) { $("#cooliris a#searchCooliris").click(); return false; } }); doCoolIrisSearch = function() { cooliris.embed.setFeedContents( '** JAVA STRING OF PARSED RSS/XML based on http%3A%2F%2Frssfeed.ucoz.com%2Frssfeed.xml and USER'S SEARCH INPUT** ' ) }); <form id="searchForm" name="searchForm" class="shockwave"> <input type="text" name="coolIrisSearch" id="coolIrisSearch" value="Search..." class="field text short" onfocus="this.value='';" /> <a id="searchCooliris" href="#" onclick="doCoolIrisSearch();return false;" class="clearLink">Search Cooliris</a> </form> <div id="gamewall"></div> So basically, I want to replace cooliris.embed.setFeedContents's value with a Javastring based on the parsed RSS/XML and user search input. Any code or ideas would be greatly appreciated.

  • Handle window scroll event in greasemonkey script

    - by Akim Khalilov
    Hi. I need some advice. I have a web page and want to extend it's functionality with greasemonkey script and firefox. When page has loaded I need run custom function during user's page scrolling (with mouse whell or scrollbar). I want show some div block when user scrolling down and hide it when he scrolling to the top. But I met some problem - I couldn't assign event handler to the onscroll event. I use next part of the code: function showFixedBlock(){ ... } function onScrollStart(){ ... showFixedBlock(); ... } window.onscroll = onScrollStart; I test this piece of code on my test html page and it works, but when I copy it into greasemonkey, script doesn't work. Should I assign onscroll event handler during page loading? As I know greasemonkey execute it's scripts when page has loaded? Is it the reason of the problem? Is there some additional requirments to handle 'onscroll' event? How can I do that? Thanks.

  • how to set a fixed color bar for pcolor in python matplotlib?

    - by user248237
    I am using pcolor with a custom color map to plot a matrix of values. I set my color map so that low values are white and high values are red, as shown below. All of my matrices have values between 0 and 20 (inclusive) and I'd like 20 to always be pure red and 0 to always be pure white, even if the matrix has values that don't span the entire range. For example, if my matrix only has values between 2 and 7, I don't want it to plot 2 as white and 7 as red, but rather color it as if the range is still 0 to 20. How can I do this? I tried using the "ticks=" option of colorbar but it did not work. Here is my current code (assume "my_matrix" contains the values to be plotted): cdict = {'red': ((0.0, 1.0, 1.0), (0.5, 1.0, 1.0), (1.0, 1.0, 1.0)), 'green': ((0.0, 1.0, 1.0), (0.5, 1.0, 1.0), (1.0, 0.0, 0.0)), 'blue': ((0.0, 1.0, 1.0), (0.5, 1.0, 1.0), (1.0, 0.0, 0.0))} my_cmap = matplotlib.colors.LinearSegmentedColormap('my_colormap', cdict, 256) colored_matrix = plt.pcolor(my_matrix, cmap=my_cmap) plt.colorbar(colored_matrix, ticks=[0, 5, 10, 15, 20]) any idea how I can fix this to get the right result? thanks very much.

  • Add an item to the Finder/Save dialog sidebar

    - by Clinton Blackmore
    I'm working on a script where a user logs into a guest account on OS and is prompted for their network credentials in order to mount their network home folder (while they benefit from working on a local user folder). As the guest folder is deleted when users log out, I want to discourage them from saving anything there. I would like to replace the items on the Finder and Open/Save sidebar lists (such as "Desktop", username, "Documents", etc) with ones that would save into their network home folder. It is possible to do this using AppleScript or Cocoa APIs, or do I need to modify a plist and restart the Finder? [Ack. Looking into ~/Library/Preferences/com.apple.sidebars.plist, it isn't at all clear how I'd populate it.] Similar Questions: AppleScript: adding mounted folder to Finder Sidebar? suggests using fstab; this code will most likely run as a user and really, automounting at that point would be too late. How do you programmatically put folder icons on the Finder sidebar, given that you have to use a custom icon for the folder? Says there is no Cocoa API, but that you can use a carbon-style LSSharedFileList API that is only documented in a single header file. Does anyone know of some example code to add an item to the Finder sidebar?

  • Programatically rebuild .exd-files when loading VBA

    - by aspartame
    Hi, After updating Microsoft Office 2007 to Office 2010 some custom VBA scripts embedded in our software failed to compile with the following error message: Object library invalid or contains references to object definitions that could not be found. As far as I know, this error is a result of a security update from Microsoft (Microsoft Security Advisory 960715). When adding ActiveX-controls to VBA scripts, information about the controls are stored in cache files on the local hard drive (.exd-files). The security update modified some of these controls, but the .exd-files were not automatically updated. When the VBA scripts try to load the old versions of the controls stored in the cached files, the error occurs. These cache-files must be removed from the hard drive in order for the controls to load successfully (which will create new, updated .exd-files automatically). What I would like to do is to programatically (using Visual C++) remove the outdated .exd-files when our software loads. When opening a VBA project using CApcProject::ApcProject.Open I set the following flag:axProjectThrowAwayCompiledState. TestHR(ApcProject.Open(pHost, (MSAPC::AxProjectFlag) (MSAPC::axProjectNormal | MSAPC::axProjectThrowAwayCompiledState))); According to the documentation, this flag should cause the VBA project to be recompiled and the temporary files to be deleted and rebuilt. I've also tried to update the checksum of the host application type library which should have the same effect. However none of these fixes seem to do the job and I'm running out of ideas. Help is very much appreciated!

  • Why do I get "mysql_query(): supplied argument is not a valid"

  • What Color is the Windows' System.Control? (Visual Studio Design View)

    - by jp2code
    In Visual Studio Design View, the selection of Form Colors in the Properties Pane are selectable from the "Custom", "Web", and "System" tabs. Of course, the color number can be used, too. When the "System" Tab is selected, the colors in the list depend on what type of Theme the Computer User has set on the PC. I'd like to stick with this, but I need to know how to "read in" the colors. I have controls that I create "on-the-fly" or often need to change a color back after getting the person's attention using a blink/flicker technique. How do I get the list of System Theme colors? Most forms have a BackColor that defaults to "Control", which looks like a very light gray under Windows 7, running the default Windows 7 Theme. I've managed to grab a color by physically reading the ARGB value in code, but I'd rather have a way to access the colors by their Theme Name, if that can be done. public Form1() { Color cControl = this.BackColor; Console.WriteLine(cControl.Name); // there is not always a name! } Does anyone know what I'm talking about?

  • Implicit Type Conversions in Reflection

    - by bradhe
    So I've written a quick bit of code to help quickly convert between business objects and view models. Not to pimp my own blog, but you can find the details here if you're interested or need to know. One issue I've run in to is that I have a custom collection type, ProductCollection, and I need to turn that in to a string[] in on my model. Obviously, since there is no default implicit cast, I'm getting an exception in my contract converter. So, I thought I would write the next little bit of code and that should solve the problem: public static implicit operator string[](ProductCollection collection) { var list = new List<string>(); foreach (var product in collection) { if (product.Id == null) { list.Add(null); } else { list.Add(product.Id.ToString()); } } return list.ToArray(); } However, it still fails with the same cast exception. I'm wondering if it has something to do with being in reflection? If so, is there anything that I can do here?? I'm open to architectural solutions, too!

  • Is it possible to send OSC commands to an iPad via the Camera Connection Kit?

    - by HELVETICADE
    I'm building a small controller device that I'd like to partner with a computer. I've settled on using OSC out from my custom built hardware and am pretty satisfied with what I can get from WOscLib. Two goals I'd like to achieve are portability and a very nice ratio between battery:computing power, and this has lured me towards using iPhoneOS to accomplish my goals. I think the iPad would suit my needs perfectly, except that using wifi to broadcast OSC out from my device requires that device to be connected to a third device with a wifi chip, and this would destroy the goal of portability, whilst also introducing potential latency and stability headaches. My question is pretty simple: Can I push OSC commands FROM my controller TO an iPad via USB and the Camera Connection Kit? If I could accomplish this, the two major goals of my project would be fulfilled very nicely. This seems like it should be a simple little question, but researching this obsessively over the past few weeks has left me more almost more uncertain than if I had done no research at all. I'd really like some more confidence before I go down this route, and it seems like it should be possible. Any insight would be very, very appreciated.

  • Executing untrusted code

    - by MainMa
    Hi, I'm building a C# application which uses plug-ins. The application must guarantee to the user that plug-ins will not do whatever they want on the user machine, and will have less privileges that the application itself (for example, the application can access its own log files, whereas plug-ins cannot). I considered three alternatives. Using System.AddIn. I tried this alternative first, because it seamed much powerful, but I'm really disappointed by the need of modifying the same code seven times in seven different projects each time I want to modify something. Besides, there is a huge number of problems to solve even for a simple Hello World application. Using System.Activator.CreateInstance(assemblyName, typeName). This is what I used in the preceding version of the application. I can't use it nevermore, because it does not provide a way to restrict permissions. Using System.Activator.CreateInstance(AppDomain domain, [...]). That's what I'm trying to implement now, but it seems that the only way to do that is to pass through ObjectHandle, which requires serialization for every used class. Although plug-ins contain WPF UserControls, which are not serializable. So is there a way to create plug-ins containing UserControls or other non serializable objects and to execute those plug-ins with a custom PermissionSet ?

  • Flex DataGridColumn with array of objects as data provider

    - by rforte
    I have a datagrid that uses an array of objects as the data provider. The objects are essentially key/value pairs: { foo:"something"} { bar:"hello"} { caca:"lorem"} The datagrid has 2 columns. The first column is the key and the second column is the value. Right now my grid looks like: My dataFormatter function makes sure that depending on the column (i.e. the dataField value) the correct key or value gets printed out. This works fine for displaying. However, as soon as I try and edit the value field it essentially adds a new value into the object with a key of '1'. For example, if I edit the {caca:"lorem"} object it will then contain the value {caca:"lorem",1:"new value"}. Is there any possible way I can set the DataGridColumn so that when I edit a value it will update the value associated with the key rather than inserting a new value? I've tried using a custom item editor but it still does the insert. It seems like I need to be able to update the 'dataField' with the actual key value but I'm not sure how to do that.

  • Project management and bundling dependencies

    - by Joshua
    I've been looking for ways to learn about the right way to manage a software project, and I've stumbled upon the following blog post. I've learned some of the things mentioned the hard way, others make sense, and yet others are still unclear to me. To sum up, the author lists a bunch of features of a project and how much those features contribute to a project's 'suckiness' for a lack of a better term. You can find the full article here: http://spot.livejournal.com/308370.html In particular, I don't understand the author's stance on bundling dependencies with your project. These are: == Bundling == Your source only comes with other code projects that it depends on [ +20 points of FAIL ] Why is this a problem, (especially given the last point)? If your source code cannot be built without first building the bundled code bits [ +10 points of FAIL ] Doesn't this necessarily have to be the case for software built against 3rd party libs? Your code needs that other code to be compiled into its library before the linker can work? If you have modified those other bundled code bits [ +40 points of FAIL ] If this is necessary for your project, then it naturally follows that you've bundled said code with yours. If you want to customize a build of some lib,say WxWidgets, you'll have to edit that projects build scripts to bulid the library that you want. Subsequently, you'll have to publish those changes to people who wish to build your code, so why not use a high level make script with the params already written in, and distribute that? Furthermore, (especially in a windows env) if your code base is dependent on a particular version of a lib (that you also need to custom compile for your project) wouldn't it be easier to give the user the code yourself (because in this case, it is unlikely that the user will already have the correct version installed)? So how would you respond to these comments, and what points may I be failing to take into consideration? Would you agree or disagree with the author's take (or mine), and why?

  • How can I determine PerlLogHandler performance impact?

    - by Timmy
    I want to create a custom Apache2 log handler, and the template that is found on the apache site is: #file:MyApache2/LogPerUser.pm #--------------------------- package MyApache2::LogPerUser; use strict; use warnings; use Apache2::RequestRec (); use Apache2::Connection (); use Fcntl qw(:flock); use File::Spec::Functions qw(catfile); use Apache2::Const -compile => qw(OK DECLINED); sub handler { my $r = shift; my ($username) = $r->uri =~ m|^/~([^/]+)|; return Apache2::Const::DECLINED unless defined $username; my $entry = sprintf qq(%s [%s] "%s" %d %d\n), $r->connection->remote_ip, scalar(localtime), $r->uri, $r->status, $r->bytes_sent; my $log_path = catfile Apache2::ServerUtil::server_root, "logs", "$username.log"; open my $fh, ">>$log_path" or die "can't open $log_path: $!"; flock $fh, LOCK_EX; print $fh $entry; close $fh; return Apache2::Const::OK; } 1; What is the performance cost of the flocks? Is this logging process done in parallel, or in serial with the HTTP request? In parallel the performance would not matter as much, but I wouldn't want the user to wait another split second to add something like this.

  • SqlCeResultSet Problem

    - by Vlad
    Hello, I have a SmartDevice project (.NetCF 2.0) configured to be tested on the USA Windows Mobile 5.0 Pocket PC R2 Emulator. My project uses SqlCe 3.0. Understanding that a SmartDevice project is "more carefull" with the device's memory I am using SqlCeResultSets. The result sets are strongly typed, autogenerated by Visual Studio 2008 using the custom tool MSResultSetGenerator. The problem I am facing is that the result set does not recognize any column names. The autogenerated code for the fields does not work. In the client code I am using InfoResultSet rs = new InfoResultSet(); rs.Open(); rs.ReadFirst(); string myFormattedDate = rs.MyDateColumn.ToString("dd/MM/yyyy"); When the execution on the emulator reaches the rs.MyDateColumn the application throws an System.IndexOutOfRangeException. Investigating the stack trace at System.Data.SqlServerCe.FieldNameLookup.GetOrdinal() at System.Data.SqlServerCe.SqlCeDataReader.GetOrdinal() I've tested the GetOrdinal method (in my autogenerated class that inherits SqlCeResultSet): this.GetOrdinal("MyDateColumn"); // throws an exception this.GetName(1); // returns "MyDateColumn" this.GetOrdinal(this.GetName(1)); //throws an exception :) [edit added] The table exists and it's filled with data. Using typed DataSets works like a charm. Regenerating the SqlCeResultSet does not solve the issue, the problem remains. The problem basically is that I am not able to access a column by it's name. The data can be accessed trough this.GetDateTime(1)using the column ordinal. The application fails executing this.GetOrdinal("MyDateColumn"). Also I have updated Visual Studio 2008 to Service Pack 1. Additionaly I am developing the project on a virtual machine with Windows XP SP 2, but in my opinion if the medium is virtual or not should have no effect on the developing. Am I doing something wrong or am I missing something? Thank you.

  • php error reporting - having trouble matching local & web server settings

    - by Andrew Heath
    I'm trying to add a custom error handler to my site, but in doing so have discovered that my webhost's PHP error reporting settings and those of my localhost (default XAMPP) vary considerably. While I thought I was programming to E_STRICT like a good little boy, adding the error handler to my webhost revealed craploads of Runtime Notices. Example: Runtime notice strtotime() [function.strtotime]: It is not safe to rely on the system's timezone settings. Please use the date.timezone setting, the TZ environment variable or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'America/Chicago' for 'CST/-6.0/no DST' instead In /home/... Clearly this isn't a red-alert, showstopping error. But what bothers me is that it doesn't show up on my localhost. I'd certainly like to improve my code by addressing these sorts of issues if I could see them! I've looked through both php.ini files, and my webhost's setting is error_reporting = E_ALL & ~E_NOTICE whereas mine was error_reporting = E_STRICT, which I had thought was better. However, changing mine to match and rebooting the server doesn't seem to have accomplished anything. Could someone please point me in the right direction?

  • Componentizing complex functionality in an MVC web app

    - by NXT
    Hi Everyone, This is question about MVC web-app architecture, and how it can be extended to handle componentizing moderately complex units of functionality. I have an MVC style web-app with a customer facing credit card charge page. I've been asked to allow the admins to enter credit card payments as well, for times when credit cards are taken over the phone. The customer facing credit card charge section of the website is currently it's own controller, with approximately 3 pages and a login. That controller is responsible for: Customer login credential authentication Credit card data collection Calling a library to do the actual charge. reporting the results to the user. I would like to extract the card data collection pages into a component of some kind so that I can easily reuse the code on the admin side of the app. Right now my components are limited to single "view" pages with PHP style embedded Perl code. This is a simple, custom MVC framework written in Perl. Right now, controllers are called directly from the framework to service web requests. My idea is to allow controllers to be called from other controllers, so that I can componentize more complex functionality. For simplicity I think I prefer composition over inheritance, even though it will require writing a bunch of pass-through methods (actions). Being Perl, I could in theory do multiple inheritance. I'm wondering if anyone with experience in other MVC web frameworks can comment on how this sort of thing is usually done. Thank you.
