• Parsing an RFC822-Datetime in .NETMF 4.0

  - by chris12892

  I have an application written in .NETMF that requires that I be able to parse an RFC822-Datetime. Normally, this would be easy, but NETMF does not have a DateTime.parse() method, nor does it have some sort of a pattern matching implementation, so I'm pretty much stuck. Any ideas? EDIT: "Intelligent" solutions are probably needed. Part of the reason this is difficult is that the datetime in question has a tendency to have extra spaces in it (but only sometimes). A simple substring solution might work one day, but fail the next when the datetime has an extra space somewhere between the parts. I do not have control over the datetime, it is from the NOAA.

• Microsoft Robotics Development Studio simulation project deployment

  - by slibby05

  I am currently working on a project in Microsoft Robotics Development Studio, and I am having a little trouble deploying the solution for general use. My problem is this. I am making a simulation, so I need to deploy the simulation engine along with my project. This is dependent on the Ageia PhysX engine, DirectX, and the Microsoft XNA framework. I understand this, and I understand that the deployment tool for MRDS (dssdeploy) isn't set up to deploy simulations by default. So, if anyone has worked with MRDS before, and has deployed a simulation, I could use some help with this.

• if_attribute on declarative authorization. STUCK FOR DAYS!!!

  - by Victor Martins

  I can't seem to find a solution for this problem :s I have a many to many relationship like this: A user has_many organizations through affiliations and vice versa. I'm using declarative organizations and I only want a user to edit a particular organization if he is affiliated and the affiliationtype attribute of affiliation is a particular value. So affiliations has 3 columns , user_id, organization_id and affiliationtype_id I can do: o = Organization.find(:first) o.affiliatons[0].user and get the user now I wish to do this: has_permission_on [:organizations], :to => :edit do if_attribute (...) end That if_attribute should see if the current user is the organization.affiliation[?].user and if the organization.affiliation[?].affiliationtype_id = "3" I hope this is syntax issue ... I really need to get this working. Thanks in advance.

• Considering migrating to silverlight - are there any official figures for silverlight propagation, a

  - by SLC

  We are considering migrating our site from flash to silverlight, and also building additional components in silverlight. However there is a strong argument that many people do not have silverlight on their computers, and will not or cannot install silverlight. Are there any official figures on how many computers have adopted silverlight, and is it a bad idea to build a company website with elements of silverlight on it? Please note I am not trying to be subjective here, I am looking for solid, official figures and also advice about whether this is considered in general by developers to be an acceptable deployment solution. I have to discuss this issue with my boss later.

• Gracefully exiting from thread in Ruby

  - by jasonbogd

  Hi, I am trying out Mongrel and using the following code: require 'rubygems' require 'mongrel' class SimpleHandler < Mongrel::HttpHandler def process(request, response) response.start(200) do |head, out| head["Content-Type"] = "text/plain" out.write("Hello World!\n") end end end h = Mongrel::HttpServer.new("0.0.0.0", "3000") h.register("/test", SimpleHandler.new) puts "Press Control-C to exit" h.run.join trap("INT") do puts "Exiting..." end Basically, this just prints out "Hello World!" when I go to localhost:3000/test. It works fine, and I can close the program with Control-C. But when I press Control-C, this gets outputted: my_web_server.rb:17:in `join': Interrupt from my_web_server.rb:17 So I tried putting that trap("INT") statement at the end, but it isn't getting called. Solution? Thanks.

• SQL orderby / case issue: orderdirection fail

  - by Joris

  I got a stored procedure that delivers a table of students, and it needs to order by surname, name etc... it also needs to sort ascending, descending, depending on the parameter @orderby... code: ORDER BY CASE WHEN @orderby = 'studentkey' THEN Studentkey END ASC, CASE WHEN @orderby = 'studentkey' and @desc = 1 THEN Studentkey END DESC, CASE WHEN @orderby = 'initials' THEN Initials END ASC, CASE WHEN @orderby = 'initials' and @desc = 1 THEN Initials END DESC, CASE WHEN @orderby = 'firstname' THEN Firstname END ASC, CASE WHEN @orderby = 'firstname' and @desc = 1 THEN Firstname END DESC, CASE WHEN @orderby = 'nickname' THEN Nickname END ASC, CASE WHEN @orderby = 'nickname' and @desc = 1 THEN Nickname END DESC, CASE WHEN @orderby = 'insertion' THEN Insertion END ASC, CASE WHEN @orderby = 'insertion' and @desc = 1 THEN Insertion END DESC, CASE WHEN @orderby = 'surname' THEN Surname END ASC, CASE WHEN @orderby = 'surname' and @desc = 1 THEN Surname END DESC NED There is a difference in output between @desc = 1 and @desc = 0, but not what i desire... Does anyone have a solution?

With regexp I don’t know how to do the replace. good...

• How can I create a JTable where the first column is always in the JScrollPane viewport?

  - by voodoogiant

  What's the best way to set up a table in a JScrollPane such that the first column is always on the screen in the same position regardless of horizontal scrolling and overlaps columns that pass underneath? When the scrollbar is at the farthest left, the columns look normal, but as the user scrolls to the right, the secondary columns (2 and on) move underneath the first until the last column appears on the far right of the viewport? I found a sample taken from Eckstein's "Java Swing" book that sort of does this, but it doesn't allow resizing of the first column. I was thinking of some scheme where one JPanel held a horizontal struct and a table holding the secondary columns and another JPanel which floated over them (fixed regardless of scrolling). The struct would be to keep the viewport range constant as the first column floated around. Ideally I could do it with two tables using the same model, but I'm not sure if the whole idea is a naive solution.

• Merge entries in CakePHP

  - by Andrea

  Let's say I have a Model, for example User, and I want to merge two instances of this Model, say merge User2 into User1. Explicitly this is what I mean: If a field is already filled in User1, it should remain the same If a field is missing in User1 but is present in User2, it should be copied If SomeModel BelongsTo User, every instance of SomeModel pointing to User2 should be modified to point to User1 Same if SomeModel HasAndBelongsToMany User If SomeModel HasMany User, and SomeModel1 Has User2 but no other instance Has User1, it should be modified so that SomeModel1 has User1 instead If SomeModel HasMany User, SomeModel1 Has User1 and SomeModel2 Has User2... well, I'm not sure here, I guess the only solution is to discard SomeModel2, since User1 can BelongTo only one SomeModel. Finally User2 should be removed. Is there a way to automate this? Maybe a Behaviour? If not, I may consider creating it, since I will need it a lot.

• Can't pass a single parameter to lambda function in MVVM Light Toolkit's RelayCommand

  - by Dave

  I don't know if there's a difference between Josh Smith's and Laurent Bugnion's implementations of RelayCommand or not, but everywhere I've looked, it sounds like the Execute portion of RelayCommand can take 0 or 1 parameters. I've only been able to get it to work with 0. When I try something like: public class Test { public RelayCommand MyCommand { get; set; } public Test() { MyCommand = new RelayCommand((param) => SomeFunc(param)); } private void SomeFunc( object param) { } } I get the error: Delegate 'System.Action' does not take '1' arguments. Just to make sure I am not insane, I went to the definition of RelayCommand to make sure I didn't have some rogue implementation in my solution somewhere, but sure enough, it was just Action, and not Action<. What on earth am I missing here?

• MSSQL Efficiently dropping a group of rows with millions and millions of rows

  - by Net Citizen

  I recently asked this question: http://stackoverflow.com/questions/2519183/ms-sql-share-identity-seed-amongst-tables (Many people wondered why) I have the following layout of a table: Table: Stars starId bigint categoryId bigint starname varchar(200) But my problem is that I have millions and millions of rows. So when I want to delete stars from the table Stars it is too intense on MS SQL. I cannot use built in partitioning for 2005+ because I do not have an enterprise license. When I do delete though, I always delete a whole category Id at a time. I thought of doing a design like this: Table: Star_1 starId bigint CategoryId bigint constaint rock=1 starname varchar(200) Table: Star_2 starId bigint CategoryId bigint constaint rock=2 starname varchar(200) In this way I can delete a whole category and hence millions of rows in O(1) by doing a simple drop table. My question is, is it a problem to have thousands of tables in your MS SQL? The drop in O(1) is extremely desirable to me. Maybe there's a completely different solution I'm not thinking of?

• Parse M3U file locations to fully qualified paths

  - by Guy

  I would like to parse the file location information in an M3U playlist into fully qualified paths. The possible formats in M3U files seem to be: c:\mydir\songs\tune.mp3 \songs\tune.mp3 ..\songs\tune.mp3 For the first example, just leave it alone. For the second add the directory that the playlist resides in so it would become c:\playlists\songs\tune.mp3 and the same for the third case so it would also become: c:\playlists\songs\tune.mp3. I'm using vb under VS2008 and I can't find a way to recognise each of the potential location formats in the M3U file. System.IO.Path offers no solution that I can find. I've searched extensively for terms like "convert relative path to absolute" but no luck. Any advice appreciated. Thanks.

• Deploying a PyQt application on Windows Vista x64

  - by Skilldrick

  I'm working on an application for a client/friend using PyQt. I've been working on Linux and testing on Vista, but the target computer is Vista x64. Now, Python comes with compiled binaries of Python 2.6 for 64 bit Windows, but Riverbank don't provide 64 bit binaries for PyQt. I don't have much access to the target computer, so I can't really go through the hassle of compiling PyQt. This Google code project might be the solution, but I'm not sure if it's going to work. Can I use something like py2exe from 32 bit Vista, or would I have to have to make the executable from a 64 bit machine with PyQt 64 bit installed? Basically, am I going to have to compile PyQt on the target machine?

• Returning errors from AMFPHP on purpose.

  - by Morieris

  When using flash remoting with amfphp, what can I write in php that will trigger the 'status' method that I set up in my Responder in Flash? Or more generally, how can I determine if the service call has failed? The ideal solution for me would be to throw some exception in php serverside, and catch that exception in flash clientside... How do other people handle server errors with flash remoting? var responder = new Responder( function() { trace("some normal execution finished successfully. this is fine."); }, function(e) { trace("how do I make this trigger when my server tells me something bad happened?"); } ); myService = new NetConnection; myService.connect("http://localhost:88/amfphp/gateway.php"); myService.call("someclass.someservice", responder);

• Migrating from VisualSVN on windows to linux based svn

  - by Jonathan

  I'd like to migrate my svn repository from my local computer running windows and VisualSVN 2.1.2 to an svn app on webfaction (my Linux hosting solution). Initially I tried dumping the svn: svnadmin dump *path_to_repository* *dumpfile_name* and loading it on the Linux machine svnadmin load *dumpfile_name* I received the following error: svnadmin: Can't open file '*dumpfile_path_and_name*/format': Not a directory I found that on my Windows machine I do have a format folder under the repository. So I copied the entire repository to the Linux machine and tried: svnadmin load *path_to_repository_copy* I received the following error: svnadmin: Expected FS format between '1' and '3'; found format '4' what should I do?

• Recommended Visual Studio config for referencing an assembly created with ILMerge

  - by Daniel Schaffer

  I have a solution in Visual Studio with 5 projects. They are: Foo.Core: Core functionality Foo.Api: Generated code built on top of core Foo.Web: Web-specific extensions Foo.Web.Mvc: MVC-specific extensions Newtonsoft.Json: 3rd party library I want to use ILMerge to merge Foo.Core, Foo.Api and Newtonsoft.Json into a single assembly, called Foo. That's the easy part. The problem I'm running into is that Foo.Web and Foo.Web.Mvc both need to reference all three of the merged assemblies. If I reference the original assemblies, they will have invalid references after I do the ILMerge. If I reference the ILMerged assembly, I have to reference a debug assembly and then change it before I package everything up, which doesn't seem ideal. I've tried creating a project called Foo, which references the 3 merged assemblies and replaces its own output with the ILmerged assembly, but that doesn't seem to work at all. Is there a reliable way to do this?

• Is regex too slow? Real life examples where simple non-regex alternative is better

  - by polygenelubricants

  I've seen people here made comments like "regex is too slow!", or "why would you do something so simple using regex!" (and then present a 10+ lines alternative instead), etc. I haven't really used regex in industrial setting, so I'm curious if there are applications where regex is demonstratably just too slow, AND where a simple non-regex alternative exists that performs significantly (maybe even asymptotically!) better. Obviously many highly-specialized string manipulations with sophisticated string algorithms will outperform regex easily, but I'm talking about cases where a simple solution exists and significantly outperforms regex. What counts as simple is subjective, of course, but I think a reasonable standard is that if it uses only String, StringBuilder, etc, then it's probably simple.

• Correct way to get absolute url in django

  - by dreamiurg

  A problem that I stumbled upon recently, and, even though I solved it, I would like to hear your opinion of what correct/simple/adopted solution would be. I'm developing website using Django + python. When I run it on local machine with "python manage.py runserver", local address is http://127.0.0.1:8000/ by default. However, on production server my app has other url, with path - like "http://server.name/myproj/" I need to generate and use permanent urls. If I'm using {% url view params %}, I'm getting paths that are relative to / , since my urls.py contains this urlpatterns = patterns('', (r'^(\d+)?$', 'myproj.myapp.views.index'), (r'^img/(.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT + '/img' }), (r'^css/(.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT + '/css' }), ) So far, I see 2 solutions: modify urls.py, include '/myproj/' in case of production run use request.build_absolute_uri() for creating link in views.py or pass some variable with 'hostname:port/path' in templates Are there prettier ways to deal with this problem? Thank you.

• Visual Studio 2005 "Add Web Deployment Project..." not showing up for web application projects.

  I downloaded the Web Deployment Project plug-in for Visual Studio 2005. I installed it. I have a project that I am working on that is a Web Application Project. The Add Web Deployment Project Build menu selection is not in the Build Menu or Solution Explorer. If I create a raw test Web Site Project, the menu item magically appears. Is this by design or am I missing something. Also, I am completely up to date on all the VS 2005 updates.

• very large string in memory

  Hi, I am writing a program for formatting 100s of MB String data (nearing a gig) into xml == And I am required to return it as a response to an HTTP (GET) request . I am using a StringWriter/XmlWriter to build an XML of the records in a loop and returning the stringWriter.ToString() during testing I saw a few --out of memory exceptions-- and quite clueless on how to find a solution? do you guys have any suggestions for a memory optimized delivery of the response? is there a memory efficient way of encoding the data? or maybe chunking the data -- I just can not think of how to return it without building the whole thing into one HUGE string object thanks

• newbie: how to upload images from a form with PHP and mySQL

  - by paracaudex

  I'm creating a web app (locally, so security doesn't matter) in PHP where the user uploads a set of information and a small .jpeg, which is then inserted into a mySQL table. I can do this no problem with all the text data, but I'm not sure how to cause the image to upload alongside it. I assume I will have to use the blob data type and input type="file", but I fooled around with that a little bit and the solution doesn't seem to be an intuitive extension of how input type="text" works. Do I need to do a lot more PHP scripting to get this to work? Is it possible to upload an image with a form, or is there a necessary intermediate step?
