  • Linq query with aggregate function OrderBy

    - by Billy Logan
    Hello everyone, I have the following LinqToEntities query, but am unsure of where or how to add the orderby clause: var results = from d in db.TBLDESIGNER join s in db.TBLDESIGN on d.ID equals s.TBLDESIGNER.ID where s.COMPLETED && d.ACTIVE let value = new { s, d} let key = new { d.ID, d.FIRST_NAME, d.LAST_NAME } group value by key into g orderby g.Key.FIRST_NAME ascending, g.Key.LAST_NAME ascending select new { ID = g.Key.ID, FirstName = g.Key.FIRST_NAME, LastName = g.Key.LAST_NAME, Count = g.Count() }; This should be sorted by First_Name ascending and then Last_Name ascending. I have tried adding ordering but It has had no effect on the result set. Could someone please provide an example of where the orderby would go assuming the query above. Thanks, Billy

  • wowza vs Flash Media Server (FMS / FMIS) - ease of integration with ASP.Net

    - by alchemical
    We're creating a web site offering one to many video chat and trying to decide on which of these streaming servers to go with. Looking at around 256kbps live streams, hoping to achieve at least 1000 simultaneous streams on one 8-core server. Wowza is cheaper (1k vs 5k for FMS), and appears to be used successfully by many sites (StreamLive, Justin.TV, etc.). However, some people have expressed that it may be more difficult to work with. I.e. fine-tuning it, less documentation, integration with ASP.Net code, etc. Wondering if anyone with real-world experience with either of these servers can advise regarding how easy or difficult to use and integrate they are for a site like this. Also wondering if there is any performance difference (lag, etc.).

  • Personalization in ASP.Net MVC -- friendly URLs, and skinning

    - by larryq
    Hi everyone, I haven't delved into custom generation of friendly URLs in ASP.Net MVC, and was wondering if anyone had suggestions. For example, if John Smith were to create an account on www.example.com, I'd like for his homepage to read www.example.com/JohnSmith -- along with the option for him to choose his URL. The ideal is for this to happen with no intervention on my part in the route maps. Also, does anyone have guidelines on good ways to go to customize an MVC site based on URL? Again, using example.com I'd like for John to choose a color theme and logo for his homepage, then apply it accordingly. Thanks for your tips and suggestions.

  • Can I pass data via JQUERY to ASP.NET MVC controller action and have a view rendered in new browser

    - by Simon Lomax
    Hi, Can anyone advise if its possible to pass data via JQUERY to an ASP.NET MVC controller action and have a view rendered in new browser tab based on the model data passed to the action method. My scenario is that I have a Jqgrid populated with product info on a page. The user would tick the items in the grid that they would like a label produced for. After they've made their slection they would click a button and I would like (if possible) to render a view of that contains a label for each selected item and have the view render in a new browser tab. All the code to allow the selections and post the relevant data back to the action method is all working fine and I know its easy to use the Jquery $(selector).load() command to populate an element on the current page with the HTML returned from the action. But is it possible to populate an element on a page in a new browser tab. If it is how would I go about it? Hope this make sense.

  • How can i customize UIPopoverController view on iPad?.

    Hai all, I am looking for a solution to customize PopoverController view in my iPad app. I need to remove the pointing icon along with the popover view and to make the view to the middle of the App window. It should go back to the button from where it is popped when we click on anywhere other than the popover view. USA TODAY app in iPad included such an option. I am not sure about how did they implemented it. Wishes your replies soon.

  • Marker Recognition on Android (recognising Rubik's Cubes)

    - by greenie
    Hi everybody. I'm developing an augmented reality application for Android that uses the phone's camera to recognise the arrangement of the coloured squares on each face of a Rubik's Cube. One thing that I am unsure about is how exactly I would go about detecting and recognising the coloured squares on each face of the cube. If you look at a Rubik's Cube then you can see that each square is one of six possible colours with a thin black border. This lead me to think that it should be relativly simply to detect a square, possibly using an existing marker detection API. My question is really, has anybody here had any experience with image recognition and Android? Ideally I'd like to be able to implement and existing API, but it would be an interesting project to do from scratch if somebody could point me in the right direction to get started. Many thanks in advance.

  • uppercase to lowercase in bash on a mac

    - by Mala
    Hi I'm writing a bash script which needs to convert a string to lowercase. The problem is I'm doing it on a mac so 'tr' is not available. How can I go about doing this on a mac? The problem I'm trying to tackle is that my script needs to recognize an if an extension is a .gif or a .jpg - and I don't want to have to check for .jpeg, .jPeg, .JPEG, .JPeg, etc etc etc... if there's a smarter way of doing this than just converting to lowercase and testing for gif, jpg and jpeg, i'm all ears :)

  • Create a polynomial object from a number using change-class

    - by charlieb
    I have written a polynomial class along the lines described in SICP 2.5.3 (except using defclass). I would like to be able to seamlessly add and multiply polynomials and regular numbers but I can't make change-class accept a number. I tried to simplify the problem by changing class from an integer to a float: (change-class 4 'float) but that gave me the error: There is no applicable method for the generic function #<STANDARD-GENERIC-FUNCTION CHANGE-CLASS (7)> when called with arguments (4 #<BUILT-IN-CLASS FLOAT>). [Condition of type SIMPLE-ERROR] I get an error of the same form from (fyi): (change-class 4 'polynomial) I'm going to go ahead and implement a manual conversion but I would prefer to use the built-in clos facilities.

  • Removing last word from FOREACH loop

    - by Stoosh
    I'm building a basic function, which builds out Mysql WHERE clauses based on how many are in the array. $array = array('id' => '3', 'name' => 'roger'); $sql = "SELECT * FROM table WHERE "; foreach ($array as $k => $v) { $sql .= $k . ' = ' . $v . ' AND '; } which will output SELECT * FROM table WHERE id = 3 AND name = roger AND However obviously I don't want that last AND, how do I go about removing it from the string? Thanks

  • MySQL Student database beginner SQL employment expectations

    - by sammysmall
    Background, Student pursuing BSIT degree, employer expectations, entry level. I would like to solicit opinions from this forum as to what your professional expectations are as regards an entry level position in working in the database realm... I see many job opportunities that require a minimum of 2 or more years experience, how does one go about obtaining this experience (I have tried very hard to maintain a minimum 3.70+ GPA) but have ZERO work experience in this field... I spend non school time working in VB and SQL to try and increase my proficiency. I have considered postponing my job search until I obtain certifications from brainbench etc... Any criticism and or advise is welcomed... Again I have no experience in database other than undergrad work in class. Thank you for your time sammysmall

  • good documentation about "avoid catching throwable", in context of weblogic server

    - by Marcel
    hi all, i am currently refactoring an existing codebase (EJBs...) to rip out all blocks where a Throwable is catched inside of the EJB. try { ... do some business logic } catch(Throwable t){ ... log and swallow ... :-( } i want/need to convince the people around me with proper documentation that "catching throwable" is a no-go for an EJB (we have lots of discussions around this :-(( ). weblogic will handle all the "Error" conditions and maybe invalidate EJBs and put fresh(working) EJBs into the pool. catching Throwable would undermine all these security nets provided by weblogic. and catching throwable is bad practice anyway (but people here are reluctant and use the "throwable" hammer everywhere). is anyone able to point me to some online docs where this behaviour is explained (for weblogic or jboss or...). i searched via google and had a look at the weblogic docs but wasn't able to find anything, just generic java doc. any help highly appreciated cheers marcel

  • Large number array compression

    - by gatapia
    Hi All, I've got a javascript application that sends a large amount of numerical data down the wire. This data is then stored in a database. I am having size issues (too much bandwidth, database getting too big). I am now ready to sacrifice some performance for compression. I was thinking of implementing a base 62 number.toString(62) and parseInt(compressed, 62). This would certainly reduce the size of the data but before I go ahead and do this I thought I would put it to the folks here as I know there must be some outside the box solution I have not considered. The basic specs are: - Compress large number arrays into strings for JSONP transfer (So I think UTF is out) - Be relatively fast, look I'm not expecting same performance as I have now but I also don't want gzip compression either. Any ideas would be greatly appreciated. Thanks Guido Tapia

  • ETW tracking from .net, user mode and driver

    - by Jack Juiceson
    Hi everyone, We have an application that parts of it are in .net, c++ usermode and C++ drivers. The application is divided into several executables that run on demand and communication with each other using LPC(the processes run in different sessions(winlogon)). Currently We have a home written logging service to which .net and c++ usermode communicate by sending LPC messages. The driver uses DbgPrint and is not always enabled, as it causes the code to run 30% slower(we have lots of logging). I want to have all the logs written in one place and preferably not writing the logger myself(I love log4cpp and log4net). The requirement is to write from all the executables and drivers into one place and to have minimal overhead. I have read that ETW is way to go, however I wasn't able to find already written logger that uses it like log4cpp or log4net. So basically my questions is, do you know if there is already implemented ETW appender for log4cpp and log4net I can use ?

  • Advantages of Thread pooling in embedded systems

    - by Microkernel
    I am looking at the advantages of threadpooling design pattern in Embedded systems. I have listed few advantages, please go through them, comment and please suggest any other possible advantages that I am missing. Scalability in systems like ucos-2 where there is limit on number of threads. Increasing capability of any task when necessary like Garbage collection (say in normal systems if garbage collection is running under one task, its not possible to speed it up, but in threadpooling we can easily speed it up). Can set limit on the max system load. Please suggest if I am missing anything.

  • Pulling and pushing between two google code repositories

    - by Kim L
    I'll start by quoting google's blog Project owners can now create multiple repositories for their project, and they can choose to make any of those new repositories a clone of any of the project's other repositories. These project clones share the same commit access permissions as the original project and make it easier for project members to work together on new features. A common pattern in the Mercurial world is to place each "official" branch into a separate repository with naming conventions like "project-crew", "project-stable", and so on. I've done exactly this. I have my default repository and then I've cloned that repository to a repo named "dev". I intend to use the default repository as my stable repo and then the dev repo as my primary development repo. Now I'm just wondering how on earth I should go about to pull and push between the default and the dev repositories?

  • Stack / base pointers in assembly

    - by flyingcrab
    I know this topic has been covered ad-naseum here, and other places on the internet - but hopefully the question is a simple one as I try to get my head around assembly... So if i understand correctly the ebp (base pointer) will point to the top of the stack, and the esp (stack pointer) will point to the bottom -- since the stack grows downward. esp therefore points to the 'current location'. So on a function call, once you've saved the ebp on the stack you insert a new stack frame - for the function. So in the case of the image below, if you started from N-3 you would go to N-2 with a function call. But when you are at N-2 - is your ebp == 25 and the esp == 24 (at least initially, before any data is placed on the stack)? Is this correct or am I of on a tangent here? Thanks!

  • Which Dependency Injection Tool Should I Use? (2)

    - by Mendy
    The original post is: Which Dependency Injection Tool Should I Use? While the original post is good, in this days I see a lot of people using StructureMap as their Dependency Injection tool, and in the original post no one even took it seriously. In addition, this quote: If I had to choose today: I would probably go with StructureMap. It has the best support for C# 3.0 language features, and the most flexibility in initialization. Which Dependency Injection Tool Should I Use? Out of this ones: Unity Framework - Microsoft StructureMap - Jeremy Miller Castle Windsor NInject Spring Framework Autofac Managed Extensibility Framework

  • VS 2010 Server Explorer Database Showing No Tables

    - by Andy
    I'm working on a .Net application that needs to read from an Oracle 10g database behind Siebel. In VS 2010 Server Explorer, I've created a connection using the OracleClient type connector with a reference to the Oracle TNS service name as the "server name." The "Test Connection" button shows that the connection is successful. However, in the Server Explorer, when I go to expand the Tables, no tables are shown. I know for a fact that there are 3000+ tables in the database (thanks Siebel). Anyone know what's happening here? I'd like to create an Entity Framework 4.0 Entity Data Model... Thanks for the help!

  • Form for Telerik RadRibbonBar?

    - by Cyclone
    I got the Telerik RadRibbonBar for free with the Express edition of vb a while back, but it did not come with any sort of form. It also, unfortunately, has the control buttons there automatically. How would I create a form which is resizable, and works like a standard winform, but doesn't have the top bar? I tried: FormBorderStyle = Sizable Text = Nothing ControlBox = False Unfortunately, when you maximize the window, it goes in front of the taskbar...and it has an ugly border when it isn't maximized. How can I: Change border color? Make it so it does not go in front of the taskbar? Thanks for the help! I'm surprised there is not some sort of form already made for this.

  • How do I debug a Net::HTTPInternalServerError error when using Mechanize?

    c:/ruby/lib/ruby/gems/1.8/gems/mechanize-1.0.0/lib/mechanize.rb:259:in `get': 500 => Net::HTTPInternalServerError (Mechanize::ResponseCodeError) I get the above error when I try to navigate to the following webpage http://fakewebsite.com//admin/edit_building.cfm?page=buildings&updateMode=yes&id=1251 I can navigate just fine when copy and paste the link into a browser. Note: This website does require a login, which I handle with code like the following $agent = Mechanize.new $agent.get('http://fakewebsite//admin/login.cfm?res=-5') form = $agent.page.forms.first form.EMail = "admin" form.Password = "password" form.submit This login works just fine, since I access other webpages protected by the login. I'm not sure where to go from here, any suggestions?

  • Curser control using Masked Text Box in C#

    - by George
    I seem to have asked this question twice ! I kept getting a message saying New Members can only add a new Question every 20 minutes, try again later !!! Sorry for the duplication ! Please ignore this one !! Thanks. In my app in C# I have several input fields that I need to capture. I need them to be of specific sizes and type and I have used masked Text Boxes for these. I have fields like name which is 20 text charachters long, and a certificate number which is 5 numeric characters with a preceding C etc. This works fine except with I click on a field with the mouse, the cursor does not go to the begining of the fild, or the end of any input text. Is there a way of allowing this to happen using Masked Text Box or will I have to use normal Text Box and do all the field validation manually ?

  • Reflecting derived classes in C#

    - by rook
    Let's assume there's a class with a virtual property (let's call it 'P'). It's overridden in a deriving class. Now I want to use something like this: obj.GetType().GetProperty("P") to get info about the overriding property. This search is ambigous, because there are two "P" properties (base and override). So I typed: obj.GetType().GetProperty("P", BindingFlags.DeclaredOnly | BindingFlags.Public | BindingFlags.Instance) It returns the overriding "P" only, but what if I can't guess in compile time if there's an override at all? The latter call would return null. The case is even more complicated, if the hierarchy of inheritance is bigger. In other words, I want to get the 'top-most' override available, otherwise - the base property. What is the cleanest way to achieve the aim? Only one I know at the moment is to go through all properties and check name and declaring type.

  • SQL server virtual memory usage and performance

    - by user365035
    Hello, I have a very large DB used mostly for analytics. The performance overall is very sluggish. I just noticed that when running the query below, the amount of virtual memory used greatly exceeds the amount of physical memory available. Currently, physical memory is 10GB (10238k bytes) whereas the virtual memory returns significantly more - 8388607k bytes. That seems really wrong, but I'm at a bit of a loss on how to proceed. USE [master]; GO select cpu_count , hyperthread_ratio , physical_memory_in_bytes / 1048576 as 'mem_MB' , virtual_memory_in_bytes / 1048576 as 'virtual_mem_MB' , max_workers_count , os_error_mode , os_priority_class from sys.dm_os_sys_info
