  • Passing constructor arguments when using StructureMap

    - by Mosh
    Hello, I'm using StructureMap for my DI. Imagine I have a class that takes 1 argument like: public class ProductProvider : IProductProvider { public ProductProvider(string connectionString) { .... } } I need to specify the "connectionString at run-time when I get an instance of IProductProvider. I have configured StructureMap as follows: ForRequestedType<IProductProvider>.TheDefault.Is.OfConcreteType<ProductProvider>(). WithCtorArgument("connectionString"); However, I don't want to call EqualTo("something...") method here as I need some facility to dynamically specify this value at run-time. My question is: how can I get an instance of IProductProvider by using ObjectFactory? Currently, I have something like: ObjectFactory.GetInstance<IProductProvider>(); But as you know, this doesn't work... Any advice would be greatly appreciated.

  • Entity Framework 5 vs Telerik OpenAccess ORM (specifically)

    - by dimoss
    I am starting a new project and want advice on choosing an ORM. I know this topic has been brought up before, but this topic is specific to either Entity Framework 5 (not 4) or Telerik OpenAccess ORM. The project will reside on Windows Azure and use Windows Azure SQL Database. I will migrate it to .NET 4.5 once 4.5 is live on Azure. I am currently a Telerik Ultimate Collection subscriber. Does anyone in the know have any pros/cons for this scenario? I am slightly leaning towards Telerik OpenAccess at the moment. Thanks

  • Unpacking Argument Lists and Instantiating WTForms objects from web.py

    - by Morris Cornell-Morgan
    After a bit of searching, I've found that it's possible to instantiate a WTForms object in web.py using the following code: form = my_form(**web.input()) web.input() returns a "dictionary-like" web.storage object, but without the double asterisks WTForms will raise an exception: TypeError: formdata should be a multidict-type wrapper that supports the 'getlist' method From the Python documentation I understand that the two asterisks are used to unpack a dictionary of named arguments. That said, I'm still a bit confused about exactly what is going on. What makes the web.storage object returned by web.input() "dictionary-like" enough that it can be unpacked by ** but not "dictionary-like" enough that it can be passed as-is to the WTForms constructor? I know that this is an extremely basic question, but any advice to help a novice programmer would be greatly appreciated!

  • Crossfading audio with PyQT4 and Phonon

    - by dwelch
    I'm trying to get audio files to crossfade with phonon. I'm using PyQT4. I have tracks queuing properly, but I'm stuck with the fade effect. I think I need to be using the KVolumeFader effect. Here's my current code: def music_play(self): self.delayedInit() self.m_media.setCurrentSource(Phonon.MediaSource(self.playlist[self.playlist_pos])) self.m_media.play() def music_stop(self): self.m_media.stop() def delayedInit(self): if not self.m_media: self.m_media = Phonon.MediaObject(self) audioOutput = Phonon.AudioOutput(Phonon.MusicCategory, self) Phonon.createPath(self.m_media, audioOutput) def enqueueNextSource(self): if len(self.playlist) >= self.playlist_pos+1: self.playlist_pos += 1 self.m_media.enqueue(Phonon.MediaSource(self.playlist[self.playlist_pos])) else: self.m_media.stop() Can anyone give me some advice on implementing the effect?

  • Is it a good practice to implement aggregate routes in Entity Framework 4?

    - by Kohan
    Having just started working on a new project using Entity Framework 4, I spoke to some of the other team that use NHibernate for advice. They implement aggregate routes on their entities, so instead of adding an order through the orders entity, they would add it through customer.order by having an addOrder method on customer. This is the approach I have taken but I am, alas, running into problems. These are issues that I hope to work out, but it got me thinking ... Is this a good way to work or am I fighting an uphill battle unnecessarily?

  • iPhone: UITableView Becomes Invisible after Changing the Data it Displays

    - by Alexander Shemshurenko
    Hi I have application with a TabBar that controls several views. In one view, I control connections to different servers. Each server provides a different set of items. I display these items in UITableView on another view. The problem is that the tableview displays OK the first time but if I go back to view number one and change the server, thereby changing the list of items that should be displayed in tableview, the tableview becomes invisible for some reason. If I tap on the screen in the place where it should be, it becomes visible again. I create table view like this UITableView * aTableView = [[UITableView alloc] initWithFrame:CGRectMake(X,Y,Width,Height) style:UITableViewStyleGrouped]; [[self view] addSubview:aTableView]; aTableView.dataSource = self; Ive tried to call reloadData and setNeedsDisplay in viewWillAppear of the UIViewController that hosts this tableview but without success. Any advice? Thanks

  • Using LaTeX, how can I have a list of references at the end of each section?

    - by celenius
    I want to generate the bibliography for each section, and have it at the end of the section. When I do this at the moment it generates the full bibliography and places it after each section. Is there a way that this can be done? The advice here says "The chapterbib package provides an option sectionbib that puts the bibliography in a \section* instead of \chapter*, something that makes sense if there is a bibliography in each chapter. This option will not work when natbib is also loaded; instead, add the option to natbib. " I don't understand what this means, and I've tried experimenting with what I thought the options are. Specifically, what does "add the option to natbib" mean? Thank you for your help.

  • Stack calling convention between .NET & C on WinCE 6.0

    - by bernard
    Hi there. I'm porting a DLL written in C from WinCE 5.0 to WinCE 6.0 on an ARM target. This DLL is called by a .NET software. On WinCE5.0, everything runs fine. On WinCE6, I have the following problem: on InitInstance() of my DLL, I can call anything without problem (for example MessageBox()) or uses recursivity. Passed that point, the DLL is called by .NET code. And then it fails: even the arguments passed by .NET code seem weird. I can call MessageBox() once, but I can't call a function that calls MessageBox() and then that calls itself: recursivity is broken. It seems that the .NET code uses the stack in a different way than my C code. I'm very unfamillar with the Windows world and the company that gives me the .NET application does not understand yet why there is such a failure. Any pointer/hint/advice welcome! Thanks!

  • Dealing with ISO-encoding in AJAX requests (prototype)

    - by acme
    I have a HTML-page, that's encoded in ISO-8859-1 and a Prototype-AJAX call that's build like this: new Ajax.Request('api.jsp', { method: 'get', parameters: {...}, onSuccess: function(transport) { var ajaxResponse = transport.responseJSON; alert(ajaxResponse.msg); } }); The api.jsp returns its data in ISO-8859-1. The response contains special characters (German Umlauts) that are not displayed correctly, even if I add a "encoding: ISO-8895-1" to the AJAX-request. Does anyone know how to fix this? If I call api.jsp in a new browser window separately the special characters are also corrupt. And I can't get any information about the used encoding in the response header. The response header looks like this: Server Apache-Coyote/1.1 Content-Type application/json Content-Length 208 Date Thu, 29 Apr 2010 14:40:24 GMT Notice: Please don't advice the usage of UTF-8. I have to deal with ISO-8859-1.

  • Why won't asp.net create cookies in localhost?

    - by James McConnell
    Okay, this is really kinda starting to bug me. I have a simple Web project setup located at: "C:\Projects\MyTestProject\". In IIS on my machine, I have mapped a virtual directory to this location so I can run my sites locally (I understand I can run it from Visual Studio, I like this method better). I have named this virtual directory "mtp" and I access it via http://localhost/mtp/index.aspx. All this is working fine. However, whenever I try to create a cookie, it simply never gets written out? I've tried this in FF3 and IE7 and it just plain won't write the cookie out. I don't get it. I do have "127.0.0.1 localhost" in my hosts file, I can't really think of anything else I can do. Thanks for any advice. James

  • "The breakpoint will not currently be hit. The source code is different from the original version."

    - by David
    Hi everyone I'm really hoping someone can help me out with this one. When debugging in Visual Studio, sometimes I add a breakpoint but it's hollow and VS says "The breakpoint will not currently be hit. The source code is different from the original version." Obviously this prevents me being able to debug. What on earth does the message mean? What original version? If I've just opened up the solution and not made any changes whatsoever to the code, how can there be an 'original version'? The appearance of this problem just seems totally arbitrary. It's just Visual Studio going 'Na na na na na, I'm not going to debug for you today'. Can anyone give any advice? Ta David

  • console windows not close after stopping program

    - by robUK
    Hello, Visual Studio 2005 C++ Windows XP Pro I have a sample application that I am testing, that links with boost libraries. However, the program runs ok. However, when I try and stop the program by clicking the 'Stop Debugging' button. The program ends, but the console window remains open. So I have many of them, as during my testing I am starting and stopping the application. Even when I try and close it by clicking the close button it has no affect. And it doesn't seem to appear under task manager when the program ends. The only way I can close them if I reboot windows. I am thinking it might be a thread that has not closed, and maybe that is keeping the console windows open. Many thanks for any advice,

  • Best Design for a Facebook clone on GAE Java

    - by charming30
    My current App is written in Python on GAE which can do Contacts management, Genealogy, Social Networking, Photo sharing, Telecom Integration (SMS, iVRS, URL Billing), CRON and performs business logic operations for our Mobile Apps. Current Architecture indlues python, django, jquery, memcache and few telecom APIs. Now, It feels that an SOA Architecture on GAE using Java would be really ideal and scalable for this kind of App where we want to build new features like widgets that users can turn on or off and third party developers can also develop and deploy features. Please correct me or improve the following design decision: UI (Current plan is GWT) Sessions, Security and ACL (Spring MVC 2.x) Reusable Business Logic components (?) Implementation of Web Services (?) Your advice would really help.

  • ASP.Net MVC - Build a load on demand TreeView

    - by Eric P
    I am wondering how to build a load on demand tree view using ASP.Net MVC. I understand what is involved in creating a JQuery TreeView using lists, but the load on demand part is really confusing me. I don't need the full solution, but can somebody point me in the right direction on where I should start? I have done these plenty of times using WinForms which keeps the view state preserved. One of the issues I am seeing is remembering all the node that have been expanded and not just the newly expanded one. If anyone had some advice, I would appreciate it. Thanks!

  • Creating a customized video using Flash and XML

    - by Aaron Ladage
    The problem: I have to create a Flash video (in CS3) that will query a MySQL database and display that data at certain points in the video. The bigger problem: I'm not a Flash/ActionScript developer, so this is all very foreign to me! I've divided this project into two parts: a.) dynamically generate an XML feed from the data using PHP (using an ID number passed in the URL's query string), and b.) be able to work with it in Flash. I've got the first part working, but am pretty lost in Flash. I can parse the XML, but I'm not sure how to set the data up as variables and attach it to a video's cue points. Can anyone point me in the direction of a good tutorial or offer some advice?

  • Are these tables too big for SQL Server or Oracle

    - by Jeffrey Cameron
    Hey all, I'm not much of a database guru so I would like some advice. Background We have 4 tables that are currently stored in Sybase IQ. We don't currently have any choice over this, we're basically stuck with what someone else decided for us. Sybase IQ is a column-oriented database that is perfect for a data warehouse. Unfortunately, my project needs to do a lot of transactional updating (we're more of an operational database) so I'm looking for more mainstream alternatives. Question Given these tables' dimensions, would anyone consider SQL Server or Oracle to be a viable alternative? Table 1 : 172 columns * 32 million rows Table 2 : 453 columns * 7 million rows Table 3 : 112 columns * 13 million rows Table 4 : 147 columns * 2.5 million rows Given the size of data what are the things I should be concerned about in terms of database choice, server configuration, memory, platform, etc.?

  • OpenMP + SSE gives no speedup

    - by Sayan Ghosh
    Hi, My Professor found out this interesting experiment of 3D Linearly separable Kernel Convolution using SSE and OpenMP, and gave the task to me to benchmark the statistics on our system. The author claims a crazy 18 fold speedup from the serial approach! Might not be always, but we were expecting at least a 2-4 times speedup running this on a Dual Core Intel. http://software.intel.com/en-us/articles/16bit-3d-convolution-sse4openmp-implementation-on-penryn-cpu/#comment-41994 Alas, we could find exactly no speedup. The serial code performs always better, with or without OpenMP. I am using Linux, and observed a certain trend...when no other processes are running on the system, after a while the loadavg starts increasing, and the the %CPU utilization falls down. Another probable false positive which I ran into accidentally...I started the program, then immediately paused it. Then I ran it on background with bg, and saw a speedup of more than 2. This happens all the time! Any advice would be great. Thanks, Sayan

  • paypal redirect on successful checkout

    - by Graeme Leighfield
    I am trying to get my Paypal subscription to redirect to a custom page after a successful checkout. Before submitting to Paypal I overload the submit handler, run my own function (to store details) and return a unique id. I want to attach that id to my return URL. (as a GET or POST var so to speak) I have turned auto redirect "on" in my Paypal sandbox sellers preferences, but it only seems to re-direct to the URL that I HAVE to put in there. using the <input type="hidden" name="return" value="someurl" /> does no seem to work. I want it this way so that I can capture the user information when entered with a "non-paid" flag, then via the IPN I can update that record with a "PAID" flag, and I want to use the unique ID to tie it all together so to speak. Any advice or a different approach is welcomed. Many thanks!

  • problem with trying to create ssms add-in

    - by Karl
    I'm trying to create an add-in for SSMS 2008 and/or 2008 R2 but I've run into a problem straight away. I can get my add-in to work and on SSMS start-up get it to simply show a message box. However, after downloading various code-samples, when trying to reference Microsoft.SqlServer.Management.UI.VSIntegration.ServiceCache I get a null reference exception: Commands2 commands = (Commands2)ServiceCache.ExtensibilityModel.Commands; I get this problem when using SSMS 2008 or SSMS 2008 R2. I'm working on Visual Studio 2010. It's a bit frustrating because I'm keen to learn more about SSMS add-ins but can't seem to get past the few samples out there. Any advice/tips appreciated. Thanks

  • How do I setup a Master Page with ASP.net?

    - by Michael
    Hi there, I'm normally a ColdFusion developer, but I'm having to work on a new site using some ASP.net hosting only, so forgive me if my questions seem very trivial. For numerous reasons, the website will be relatively static in the sense that it will mainly be using includes etc...that's about as complex as it will get with this. Now, I heard about the ability to set a master in ASP.net. Would anyone please be able to explain to me in a step process on how to do this? I have of course been searching for some time now on this topic but most results yield little help or no help at all since the search terms are slightly ambiguous. It would be nice to have this functionality for the long run. Any help or advice would be great. Many thanks. Michael.

  • using macro defined in header files

    - by Neeraj
    I have a macro definition in header file like this: // header.h ARRAY_SZ(a) = ((int) sizeof(a)/sizeof(a[0])); This is defined in some header file, which includes some more header files. Now, i need to use this macro in some source file that has no other reason to include header.h or any other header files included in header.h, so should i redefine the macro in my source file or simply include the header file header.h. Will the latter approach affect the code size/compile time (I think yes), or runtime (i think no)? Your advice on this!

  • NSPredicates with custom objects

    - by Horatiu Paraschiv
    Hi, I have the following problem and I cannot figure out how to solve it. I have an NSSet which contains Person objects (NSDictionary with 2 keys: name, age). From time to time I get an NSArray of Person objects and I want to add them to my NSSet but I want to filter out the duplicates. I'm thinking I could use NSPredicates but I am reading the documentation and I can't understand how should I format my NSPredicate to filter out my array content based on what I already have in NSSet. So I have an NSSet with 5 custom objects and I get an NSArray with 6 objects but 3 of them already exist in NSSet and I want to filter them out. I understand what I should do with basic objects like Strings, integers, etc but I don't know how to extend this to work with custom more complex objects. I hope I was clear enough with my problem. Any starting point, example or advice is much appreciated. Thank you!

  • How to fix rotations in a Rubik's Cube?

    - by Eindbaas
    I'm trying to create a Rubik's Cube in Flash & Papervision and i'm really stuck here. I'm up to the point where i can rotate any plane of cubes once, but after that...it's messed up because all local coordinate systems are messy. I dont really know where to go from here, can anybody give any advice on what do do? I'm not looking for 'read about transformation matrices', i know i should (and i am doing that), but i'm not really sure what to look for. My idea is that, after each rotation, i should fix each coordinate system of each cube again, but i have no idea how. Any hints on what i want to achieve (in words), and why, are much appreciated. http://dl.dropbox.com/u/250155/rubik/main.html (you can press the K key once ;) )
