• Rewrite content served by apache

  - by Andy

  Hi guys, I have an internal app (Jira) that i want to use internally and externally, now there might be another way of doing this in which case i'm open to it, but this is what i have so far: URL one: https://domainname.com/jira - external domain name for it URL two: https://domainname.local/jira - internal network name for it. I am running Apache as a reverse proxy and I have this: <Location /jira> ProxyPass http://127.0.0.1:8080/jira ProxyPassReverse http://127.0.0.1:8080/jira </Location> Jira creates all of its links using a base url, which in this case is set to 'https://domainname.local/jira', so obviously when pages get served to the outside world they have .local on them. The question is, is there a way to have the content rewritten as it is served in order to change the .local addresses within the HTML to be the .com ones? Or am i being a retard and there is an easier way to solve this? Cheers for any help.... Andy

• First Fluent NHibernate Project

  - by Andy

  I'm trying to follow the "Your first project" tutorial at http://wiki.fluentnhibernate.org/Getting_started and have hit a roadblock. When I try to run the console application, I'm getting this error: An invalid or incomplete configuration was used while creating a SessionFactory. Check PotentialReasons collection, and InnerException for more detail. I have created a SQLite database "firstProject.db" and referenced the full path to the file in the call to: return Fluently.Configure() .Database(SQLiteConfiguration.Standard .UsingFile(DbFile)) .Mappings(m => m.FluentMappings.AddFromAssemblyOf<Program>()) .ExposeConfiguration(BuildSchema) .BuildSessionFactory(); so I don't know what I'm doing wrong. What/where is this "PotentialReasons" collection? Thank you for the help. Andy

• Can Windows Mobile Synch Services use a business layer

  - by Andy Kakembo

  We're building a Win Mobile 6 warehouse app which needs to update our server based corporate DB. We've got a C# business layer that sits on our app server and we'd really like our warehouse app to go through this. We also like MS Synch Services. Is there a way to combine the two ie can we use sync services but get them to go through our business layer ? Has anyone done this and got an example I can follow ? Is there a best practice for this kind of scenario ? Thanks, Andy

• Page loading effect with jquery

  - by Andy Simpson

  Hello all, Is there a way to use jquery (or other method) to display a loading div while page loads? I have a table that is populated using PHP/MySQL and can contain several thousand rows. This is then sorted using the tablesorter plugin for jquery. Everything works fine, however the page can sometimes take 4-5 seconds to fully load and it would be nice to display a 'loading...' message within a div which automatically disappears when whole table is loaded. I have heard of loadmask plugin for jquery - would this be suitable for my needs and if not any alternative? No AJAX calls are being made while loading this table if thats relevant. Thanks in advance Andy

• Sending information back from delegate [iPhone]

  - by Andy

  I'm using NSXMLParser in my RootViewController.m file. NSXMLParser *xmlParser = [[NSXMLParser alloc] initWithData:response_data]; [xmlParser setDelegate:self]; [xmlParser parse]; [xmlParser release]; I'm also implementing this method to add entries to a dictionary defined in RootViewController.m for later use: - (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName attributes:(NSDictionary *)attributeDict However, I'd like to get more than one XML file and do different things when the file has finished; this sounds like I need to use external files as delegates. My question is: If I have the following implementation files (& their header files): RootViewController.m XMLDelegate1.m XMLDelegate2.m and set the ith NSXMLParser delegate to be XMLDelegatei.m, and get those files to return an NSDictionary that I can then add to the NSDictionary defined in RootViewController.m. I guess there are two methods of doing this: Use a method that I don't know about; or Use a better workflow I suspect it's 2, but hope it's 1. Thanks, Andy

• C# Entity Framework Base Repository

  - by Andy

  I'm trying to create a base repository for use with Entity Framework 4.0 and having some trouble. In this code below, why is it not possible to do this in one line? public IEnumerable<T> GetAll<T>(Expression<Func<T, bool>> filter) { IEnumerable<T> allCustomers = this.GetAll<T>(); IEnumerable<T> result = allCustomers.Where(filter.Compile()); return result; } Won't this result in 2 SQL statements: one without a where clause that retrieves all rows, and one with a where clause that only retrieves the rows that match the predicate? How can this be done with a single SQL statement? I can't get it to compile if I try to cast the filter.Compile() to Func<Customer, bool>. Thanks, Andy

• gcc architecture question

  - by Andy

  Hi, I'm compiling my program with architecture set to -mtune=i386 However, I'm also linking statically against several libs (libpng, zlib, jpeglib, vorbisfile, libogg). I've built these libs on my own using configure and make, so I guess these libs were built with architecture being set to my system's architecture which would be i686. But I don't want that! I want my program to run on i386, too, so I need to make sure that all these libs that I'm statically linking against are built for i386, too. So my question: Is there a convenient way to build libpng/zlib/jpeglib/vorbisfile/libogg etc. for i386 or do I have to modify all of their makefiles manually and make sure that -mtune is set to i386? Thanks for help! Andy

• Getting Started with Fluent NHibernate

  - by Andy

  I'm trying to get into using Fluent NHibernate, and I have a couple questions. I'm finding the documentation to be lacking. I understand that Fluent NHibernate / NHibernate allows you to auto-generate a database schema. Do people usually only do this for Test/Dev databases? Or is that OK to do for a production database? If it's ok for production, how do you make sure that you're not blowing away production data every time you run your app? Once the database schema is already created, and you have production data, when new tables/columns/etc. need to be added to the Test and/or Production database, do people allow NHibernate to do this, or should this be done manually? Is there any REALLY GOOD documentation on Fluent NHibernate? (Please don't point me to the wiki because in following along with the "Your first project" code building it myself, I was getting run-time errors because they forget to tell you to add a reference. Not cool.) Thanks, Andy

• X11 and ARGB visuals: does DefaultDepth() never return 32?

  - by Andy

  Hi, I'm establishing a connection to the X server like this: display = XOpenDisplay(NULL); screen = DefaultScreen(display); depth = DefaultDepth(display, screen); I'm wondering now why "depth" is always set to 24. I would expect that it is only 24 when compositing is turned off, but in fact, it is still 24 even when I turn on compositing. So in order to get a 32-bit ARGB visual I need to call XGetVisualInfo() first with depth set explicitly to 32. Now to my question: Will DefaultDepth() generally never return more than 24 or is it just on my system? (my graphics board is somewhat dated...). I know that it could return 15, 16 or even 8 for a CLUT display but can it return 32? Or do I always have to use XGetVisualInfo() first to get a ARGB 32-bit visual? Thanks, Andy

• Are there any good books on writing commercial quality software?

  - by Andy

  Hey, My background has been generally new technology demonstrators, which, well... demonstrate the latest technology and how it can be of use to a clients company. They use it for internal demos etc. Now my career has shiffed course a bit more into actual products, in particular software which runs in locations like museums as interactive pieces. Clearly, although the technology demonstrators had to be well coded etc, there wasn't as much emphasis as there is on my current work, which has to work, be highly configurable, probably multi-ligual and run constantly, without restarts. So my question is, now that I'm trying to up my coding quality and write more commercial applications, are there any books which discuss issues surrounding high quality commercial software? I currently have a copy of Code Complete 2nd Edition, which is excellent, but just wondering if there's any better, possibly more focused titles out there? Thanks a lot! Andy.

• Stop sign icon in VS2005 Express solution explorer

  - by Andy Bisson

  What does a small stop sign icon on a file in solution explorer mean? Someone asked the same question a year ago Original Question but the answer provided is of no help. The icon looks like this: Suffice to say that the sign is not one presented in the VS documentation and is a UK Stop sign (red circle with a white horizontal bar) not a US one. The project is WebKit and the build process cannot find AuthenticationCF.h even though the file is present. I presume the sign might shed some light on this. Thanks, Andy

• hibernate transaction safety (with, without JBoss)

  - by Andy Nuss

  Hi, I am currently using just Hibernate and tomcat (no JBoss), and have hibernate transactions which I'm not clear on what transaction safety level I'm actually using, especially for those which read and get values and then update them). Thus I might be getting dirty reads? So I'm going to start having to study my transactions that require non-dirty reads, and make sure that (1) hibernate controls the transaction safety level of those transactions properly, and (2) be able to still have those transactions where dirty reads are ok. Do I need to install Hibernate with JBoss to control transaction safety levels? If so, what's the easiest way to do this without dramatically changing my application to use the J2EE apis, as I am currently using the basic Hibernate apis. Or better, can I get JTA control with Hibernate without using JBoss? Andy

• C# Class Factories

  - by Andy

  I have a class called Foo that has a function that looks like the following List<Bar> LoadData(); Both Foo and Bar are in a library that I want to reuse in other projects. Now I am working on a new project and I want to subclass Bar. Let's call it NewBar. What is a simple and flexible way to get Foo.LoadData to return a list of NewBar? I think that a factory is needed or perhaps just a delegate function. Can anyone provide an example? Thanks, Andy

• C#, Generic Lists and Inheritance

  - by Andy

  I have a class called Foo that defines a list of objects of type A: class Foo { List<A> Items = new List<A>(); } I have a class called Bar that can save and load lists of objects of type B: class Bar { void Save(List<B> ComplexItems); List<B> Load(); } B is a child of A. Foo, Bar, A and B are in a library and the user can create children of any of the classes. What I would like to do is something like the following: Foo MyFoo = new Foo(); Bar MyBar = new Bar(); MyFoo.Items = MyBar.Load(); MyBar.Save(MyFoo.Items); Obviously this won't work. Is there a clever way to do this that avoids creating intermediate lists? thanks, Andy

• Handling async ASMX web service exceptions

  - by Andy

  Hi, I've developed silverlight client with makes async web services calls to a asmx web service. The problem is, I want to handle exceptions, so far as to be able to tell in the client application whether there was an exception in the webservice (and therefore will be logged local to the webservice) or whether there was a communication problem (i.e. the endpoint for the webservice was wrong). In testing both types of exceptions in my project I get the same generic exception: System.ServiceModel.CommunicationException: The remote server returned an error: NotFound. This exception is amazingly useless when an exception occured in the webservice as it clearly has been found. Is the presence of this generic error to do with security (not being allowed to see true errors)? It can't be the fact that I don't have debug strings as I'm running on a dev PC. Either way, my question is, what's the best way to handle async errors in a commercial silverlight application? Any links or ideas are most welcome! :) Thanks a lot! Andy.

• Grep failing with Emacs (windows), and GnuWin32 Grep

  - by Andy

  Hi, I've downloaded and installed the GnuWin32 tools, and added the grep executables to the Emacs bin. I've also, for what its worth, added the GnuWin32 bin folder to my Path variable. Problem is though, when I try and run with suggested grep commands, I always get: Grep exited abnormally with code 53 at Wed Feb 24 17:16:12 For the life of me, I can't find any reference to error code 53 anywhere! :( I've tried the exact examples on a number of websites for example, when I enter: M-x grep <ret> It comes up with Run grep (like this): grep -n Which is fine, but I have no idea of what parameters it expects. I've tried some in some tuorials, but I get error code 53 again! One of the things I've tried is straight from the emacs wiki (http://www.emacswiki.org/emacs/GrepMode#toc2) (maybe not for the windows version though?) and it says to try this command: M-x grep -n -e setq ~/.emacs Which I've tried and I get: -*- mode: grep; default-directory: "c:/[My Directory]/" -*- Grep started at Wed Feb 24 17:30:47 grep -n -e setq ~/.emacs NUL Grep exited abnormally with code 53 at Wed Feb 24 17:30:47 So frustrating as this is meant to be a powerful feature of Emacs and I'm really trying to learn it as I've heard good things about it! Any help would be appreciated! :) Andy UPDATE From the suggestion below, I've tried it via command line and it seems to work fine, perhaps there some config I'm UPDATE I've found the command M-x Occur which seems to do much the same as I would image grep does. Are there many extra benefits to using grep over occur if I can't get this working?

• Fluent NHibernate is bringing ClassMap Id and SubClassMap Id to referenced table?

  - by Andy

  HI, I have the following entities I'm trying to map: public class Product { public int ProductId { get; private set; } public string Name { get; set; } } public class SpecialProduct : Product { public ICollection<Option> Options { get; private set; } } public class Option { public int OptionId { get; private set; } } And the following mappings: public class ProductMap : ClassMap<Product> { public ProductMap() { Id( x => x.ProductId ); Map( x => x.Name ); } public class SpecialProductMap : SubclassMap<SpecialProduct> { public SpecialProductMap() { Extends<ProductMap>(); HasMany( p => p.Options ).AsSet().Cascade.SaveUpdate(); } } public class OptionMap : ClassMap<Option> { public OptionMap() { Id( x => x.OptionId ); } } The problem is that my tables end up like this: Product -------- ProductId Name SpecialProduct -------------- ProductId Option ------------ OptionId ProductId // This is wrong SpecialProductId // This is wrong There should only be the one ProductId and single reference to the SpecialProduct table, but we get "both" Ids and two references to SpecialProduct.ProductId. Any ideas? Thanks Andy

• Blank subreport in Jasper Reports

  - by Andy Chapman

  Hi all, I'm trying to launch a report that I created in iReport which contains a main report and a subreport. In iReport, the subreport launches fine and contains data, however when I try to launch it from within my java code, the subreport is blank. What I've done so far: I have a String parameter in the main report called "SUBREPORT" that is used to define the path to the subreport. E.g. value: "E:\java\ReportLauncher\reports\test_subreport1.jasper" The subreport expression in the main report is set to: $P{SUBREPORT} The subreport connection expression is: $P{REPORT_CONNECTION} I also have a subreport parameter defined called "INVOICE_NUMBER" that is set to $F{InviInvNo}, which maps to a field in the main report. In my java code, I have: HashMap<String, Object> paramHash = new HashMap(); paramHash.put("INVOICE_NUMBER", invoiceID); paramHash.put("REPORT_CONNECTION", this.conn); paramHash.put("SUBREPORT", subReportPath); JasperPrint jasperprint = JasperFillManager.fillReport(this.reportPath, paramHash, this.conn); The main report is created fine and is populated. The subreport area however is blank. Any thoughts for what I'm doing wrong? Thanks in advance, Andy.

• wpf - window to be tight round user control

  - by Andy Clarke

  Hi, I've got a user control that I'm loading into a Window dynamically - I wanted to set the Window so that it didn't have a size and then I thought the window to resize accordingly depending on the UserControl. However it dosn't - can anyone assist please? I've made a very basic example - I've cut out the dynamic bits and just put a UserControl in a Window. What do I need to do to get the window to be tight around the UserControl? Thanks, Andy <UserControl x:Class="WpfApplication1.UserControl1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Height="300" Width="300" Background="LightBlue"> <Grid> </Grid> </UserControl> <Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:WpfApplication1="clr-namespace:WpfApplication1" Title="Window1" > <Grid> <WpfApplication1:UserControl1> </WpfApplication1:UserControl1> </Grid> </Window>

• Why does my Sax Parser produce no results after using InputStream Read?

  - by Andy Barlow

  Hello, I have this piece of code which I'm hoping will be able to tell me how much data I have downloaded (and soon put it in a progress bar), and then parse the results through my Sax Parser. If I comment out basically everything above the //xr.parse(new InputSource(request.getInputStream())); line and swap the xr.parse's over, it works fine. But at the moment, my Sax parser tells me I have nothing. Is it something to do with is.read (buffer) section? Also, just as a note, request is a HttpURLConnection with various signatures. /*Input stream to read from our connection*/ InputStream is = request.getInputStream(); /*we make a 2 Kb buffer to accelerate the download, instead of reading the file a byte at once*/ byte [ ] buffer = new byte [ 2048 ] ; /*How many bytes do we have already downloaded*/ int totBytes,bytes,sumBytes = 0; totBytes = request.getContentLength () ; while ( true ) { /*How many bytes we got*/ bytes = is.read (buffer); /*If no more byte, we're done with the download*/ if ( bytes <= 0 ) break; sumBytes+= bytes; Log.v("XML", sumBytes + " of " + totBytes + " " + ( ( float ) sumBytes/ ( float ) totBytes ) *100 + "% done" ); } /* Parse the xml-data from our URL. */ // OLD, and works if comment all the above //xr.parse(new InputSource(request.getInputStream())); xr.parse(new InputSource(is)) /* Parsing has finished. */; Can anyone help me at all?? Kind regards, Andy

• Problem with response.redirect sending incorrect HTTPMethod

  - by Andy Macnaughton-Jones

  Hi, I've got a strange problem with a Response.Redirect. I'm using VB.NET with the .NET 2 framework (so VS2005 & SP1). I've got a page that I do a form submit on (that's a proper form method="POST" hard-coded onto the page) and that properly posts me back the page data which is then processed. As part of that processing the system determines if we need to get sent to another URL after processing has been complete. So the request.httpmethod = "POST". So if the "GotoPage" parameter has a URL specified we then do a response.redirect(URL, false). (False as we want page processing to complete in order to write some timing logs etc). The page correctly redirects but instead of the response having a "GET" as the request.httpmethod it has a "POST" instead ! Now, we're using our own custom framework so that we use the HTTPRequest method to determine if a page has been posted back or is being "Getted" so the "IsPagePostBack" property doesn't work (that only works when you're using the normal .NET controls and form submissions). In all other instances our code works happily but what might be causing the Request.httpMethod to not be being set correctly ? I've tried doing a response.clear before the redirect in case headers are being written out before hand but to no avail. Any clues ?! thanks, Andy

• jquery loop to create elements with retained values

  - by Andy Simpson

  Dear all, I recently asked a question about creating elements with jquery. Specifically I needed input boxes created/deleted depending on the value of a particular select box. This was answered quickly with a very nice solution as follows: $('select').change(function() { var num = parseInt($(this).val(), 10); var container = $('<div />'); for(var i = 1; i <= num; i++) { container.append('<input id="id'+i+'" name="name'+i+'" />'); } $('somewhere').html(container); }); This works very well. Is there a way to have the values remaining in the text boxes when the selection is changed? For example, lets say the select element value is set to '2' so that there are 2 input boxes showing. If there is input already entered in these boxes and the user changes the select element value to '3' is there a way to get the first 2 input boxes to retain their value? Thanks for the help in advance Andy

• 3 Servers, is this is a cluster?

  - by Andy Barlow

  Hello, At the moment I have one Ubuntu server, 9.10, running with a simple Samba share, a mail server, DNS server and DHCP server. Mostly its just there for file sharing and email server. I also have 2 other servers that are exactly the same hardware and spec as the first, which have an rsync set up to retrieve the shared folders and backs them up. However, if the first server goes down, all of our shares disappear along with our mail and the system must be rebuilt. Also I tend to find if people are downloading a large amount from the file server, no-one can access there emails - especially in the morning when everyone is signing in at once. Would it be more beneficial for me to have all 3 servers, all running the same services, doing the same thing with some sort of cluster with load balancing? I'm not really sure where to begin looking, or how to go about such a setup where 3 servers are all identical, but perhaps one acts as the main load balancer?? If someone can point me in the right direction, or if this simply sounds like one of those Enterprise Cloud's that is now a default setup in Ubuntu Server 9.10+, then I'll go down that route. Cheers in advance. Andy
