• Use LINQ to SQL results inside SQL Server stored procedure

  - by ifwdev

  Note: I'm not trying to call a SQL Server stored proc using a L2SQL datacontext. I use LINQPad for some fairly complex "reporting" that takes L2SQL output saved to an Array and is processed further. For example, it's usually much easier to do multiple levels of grouping with LINQ to Objects instead of trying to optimize a T-SQL query to run in a reasonable amount of time. What would be the easiest way to take the end result of one of these "applications" and use that in a SQL Server 2008 stored proc? The idea is to use the data for a Reporting Services Report, rather than copying and pasting into Excel (manual labor). The reports need to be accessible on the report server (not using the Report Server control in an application). I could output CSV and read that somehow via command line exec, but that seems like a hack. Thanks for your help.

• Problem with running a program from flashdrive

  - by rajivpradeep

  I have a USB drive with two partitions in it, one hidden and one normal. I have an application which swaps the memory and runs the flash application in hidden zone. The problem is that the application works fine on Windows 7 and when run on Win XP, it swaps the partitions but doesn't run the flash applications but just keeps running in the background. I can see it in task manager. But, when I copy the application to desktop and run, it runs with no glitch. I was facing the same problem on Win 7 too, but it was running as required when I ran it using "Run in XP mode" and then I applied a SHIM and is running since then as required. The application is built using VC++ 2008. What might be the problem?

• What is the best method for implementing mouse wheel activity in Delph1 VCL forms?

  - by Brian Frost

  As a long time user of Delphi 7, I've rolled my own mouse wheel handling in a few controls but lately I've noticed that some recent applications only need the mouse cursor to be placed over a control (e.g a list box or tree view) for the mouse wheel activity to cause that control to scroll. This feels nice (as opposed to having to click focus a control before it responds to the wheel. Now I've moved to Delphi 2010 I'm wondering what is the 'correct' behaviour? And what can I use in Delphi that avoids me having to bodge this with my own solutions now? Thanks.

• How Does a Login system generally work with OOP?

  - by fakingfantastic

  Sorry if this is a badly formed question, but I'm trying to make my web applications (using PHP) more OO. *EDIT* I'm developing the Framework myself */EDIT* Everything is great so far, I've made a Front Controller system that taps into a MVC system. The FC figures out what page you want, loads the specific page Controller (*EDIT* which extends an abstract Controller Object */EDIT*), which gets anything it needs from Models, and then calls the appropriate View. Very basic. But now, I need to make an admin section (quasi-CMS). How does a login system fit into the grand scheme of things? Do you set controllers as needing a login? If so, how? What If you only want certain views of a controller requiring login? Thanks in advance.

  Hi everybody, i have a doub... Is posible implement the business logic in an App Server remote using pojos instead of either EJB or Servlets???. The main idea is apply a model of 3 layers where the clients may be both web browsers and desktop applications, and they share the business logic in an App Server. Sorry for my english... im from Argentina and my english is poor. Thank you to everybody and i hope that anybody can help me soon. Regards! this would be the architecture browser----- Web Server --------|App Server(Business Logic common)|-------|RDBMS common| desktop App(Swing for example)-|App Server(Business Logic common)|-------|RDBMS common|

• CSS cross browser compatibility on Ubuntu

  - by bhefny

  Hello, I'm currently working in web development and my default desktop is Ubuntu and I'm kind of happy with the setup and applications I got going. But I need to test web pages for cross browser compatibility while still being on Ubuntu. I have gone through hell trying to get IE7 or IE8 (with wine) to run on ubuntu and when they finally worked they were very buggy and the graphics/scrolling was insanely slow. Of course there is the option of virtual box but again, too much GBytes just to run a small application! So to all the CSS gurus out there, how can I continue with my beloved Ubuntu and still deliver a good quality (tested) page. Thank you.

• Python extension building with boost

  - by user1544053

  Hey guys I'm fairly new to boost c/c++ library. I downloaded boost library and build the library. I created a very simple python library in c++ using boost interface (actually it is example code given in the documentation). I built it into a dll file. In the documentation it reads that this dll is exposed to python and they just show the import function in python and include the created library. I don't understand how to expose that dll to python and load the library inside in tradition ('import') manner. In case if you wanna look at the code then here it is: #include <boost/python.hpp> char const* greet() { return "hello, world"; } BOOST_PYTHON_MODULE(hello_ext) { using namespace boost::python; def("greet", greet); } Please help I really want to build applications with c/c++ and python. I simply want to use hello_ext as: >>>import hello_ext >>>print hello_ext.greet() Thank you.

• What are some best practices for making sure your .NET code will scale well?

  - by billmaya

  Last week I interviewed for a position at a TripleA MMORPG game company here in NE. I didn't get the job but one of the areas that came up during the interview was the about the scalability of the code that you write and how it should be considered early on in the design of your architecture and classes. Sadly to say I've never thought very much about the scalability of the .NET code that I've written (I work with single user desktop and mobile applications and our major concerns are usually with device memory and rates of data transmission). I'm interested in learning more about writing code that scales up well so it can handle a wide range of remote users in a client server environment, specifically MMORPGs. Are there any books, web sites, best practices, etc. that could get me started researching this topic?

• Move Global.asax to iHttpModule when using ASP.NET MVC

  - by rockinthesixstring

  I have successfully created an iHttpModule to replace my Global.asax file in many Web Forms applications. But in looking at the Global.asax file in my MVC application, the methods are totally different. I'm wondering if it is still possible to create this same thing in an MVC app. I know it's not necessary and the Global.asax works just fine. I suppose I just want to have nothing but the web.config in the root directory of my application. Also, I am putting all of my classes in a separate class library project instead of a folder in my MVC application. Not sure if this makes a difference or not.

• Actors in Scala.net

  - by weijiajun

  I have recently completed some study of erlang, and was intrigued by scala for its feature set and the ease of interpolating with java (and possibly .net) applications. I am finally studying actors and was wondering if there is an actor mechanism that currently works in .net. I have looked at the libararies that come down with sbaz and have found that there is a scala.Concurrent but no scala.actors.Actor. I tried to use the scala.Concurrent.Channel but was unable to use the ! to send messages. I was just wondering if this is something that is currently available and if so how do you go about setting it up.

• Agile - When does it work well, and when doesn't it?

  - by Randy Minder

  Our team is debating whether we want to become Agile or not. None of us are really fluent in Agile. I'd like some thoughts on when Agile works well, and when it doesn't? To give a little background, we are a small group of developers, six in total. We have far more work that we can handle. Our priorities change often. What is a high priority today, may not be tomorrow. We have many applications to create and maintain. If you need more information to answer this, please feel free to ask. Thanks.

• Is there any framework for Windows Forms, DB driven application development/prototyping?

  - by dolzenko

  I'm writing simple database driven application, 80% of functionality is CRUD operations on about 15 tables. Coming from web development background I figured I can cover almost all of these CRUD cases with Rails scaffolding or say Django admins. So I started to look around for Rails/Django-like framework but for Windows Forms applications (ofcourse I understand that "rich client" application development significantly differs from a web development and I'm not expecting anything really similar). I was surprised that except for a variety of ORMs (let's call it Model-layer) it seems like I'm left with little choice when it comes to View-Controller layer. Maybe I'm missing something? PS. I evaluated Visual Studio DataSet Designer, but it seems to work only for the most simple cases, and requires additional code for any slightly nontrivial task. (added) so far I've found: TrueView for .NET (thanks to Vijay Patel) NConstruct

• Java - Robot keyPress issue

  - by Trimbitas Sorin

  I'm trying to send keystrokes (like a virtual keyboard) from my Java code, but I encounter some issues. It works perfectly on normal applications (for example, Notepad, browsers, etc.), but not on games (fullscreen or windowed mode). This is the stripped code I'm using: import java.awt.Robot; import java.awt.AWTException; import java.awt.event.InputEvent; Robot robot; robot.keyPress(KeyEvent.VK_A); robot.keyRelease(KeyEvent.VK_A); How can this problem be fixed?

• Using CreateFileMapping between to programs - C

  - by Jamie Keeling

  Hello, I have two window form applications written in C, one holds a struct consisting of two integers, another will receive it using the CreateFileMapping. Although not directly related I want to have three events in place so each of the processes can "speak" to each other, one saying that the first program has something to pass to the second, one saying the first one has closed and another saying the second one has closed. What would be the best way about doing this exactly? I've looked at the MSDN entry for the CreateFileMapping operation but I'm still not sure as to how it should be done. I didn't want to start implementing it without having some sort of clear idea as to what I need to do. Thanks for your time.

• Naive question about implementing RSS

  - by interstar

  I have a naive question about RSS feeds. I have a series of timed events which appear on my site and that I make available as an RSS feed for other applications to import. Who is typically responsible for truncating this feed? Over the next year, I can see my feed having thousands of items. Should the URL mysite.com/rss always return all items? And leave it to the readers to just show the most recent? Or is it more customary that I only return, say, the top 50? Expecting the readers to cache older items? (And, if so, is there a convention for readers to ask the server for the "next page")? What is the typical behaviour of something like FriendFeed when it pulls in an RSS stream?

• Physical Cores vs Virtual Cores in Parallelism

  - by Code Curiosity

  When it comes to virtualization, I have been deliberating on the relationship between the physical cores and the virtual cores, especially in how it effects applications employing parallelism. For example, in a VM scenario, if there are less physical cores than there are virtual cores, if that's possible, what's the effect or limits placed on the application's parallel processing? I'm asking, because in my environment, it's not disclosed as to what the physical architecture is. Is there still much advantage to parallelizing if the application lives on a dual core VM hosted on a single core physical machine?

• Code Signing Identity does not match in my keychain, for mac app store developing?

  - by larntin

  hi, 1, I already download the "Apple Worldwide Developer Relations Certification Authority",and add it into my keychain. 2, My team leader already had created two Cers for Mac App store developing, I download and add it into my keychain. 3, I used two methods to sign my add, but failed all. First, add code sign section in my .xcodeproj(3.2.5). Second, I used script: productbuild --component ./bin/MAS_Release/MyApp.app /Applications --sign "3rd Party Mac Developer Application: My Company Co., Ltd." --product ./src/MyApp/MyApp-Info.plist MyApp.pkg But it failed with information: Code Signing Identity '3rd Party Mac Developer Application: My Company Co., Ltd.' does not match any valid, non-expired, code-signing certificate in your keychain. I observed that my certifications in keychain don't have small trangle. how make the small trangle absence?(when I'am importing the Cers from my Agent, it don't have the trangle absence)

• Architecture Guidance for designing Workflow Foundation with WCF

  - by Matrix

  We are planning to use WF 3.5 with WCF 3.5 and Entity Framework 1.0 for the upcoming major project. I'm looking for guidance on the architecture side. This new application will be based on typical 3-tier architecture as depicted below: Presentation Tier: ASP.NET Web Forms 3.5 Business Tier: WF 3.5 + BLL's that expose the business logic through WCF service interfaces (using EF for Data Access) Data Tier: SQL Server 2000 Here are the questions: Though the Workflow Foundation has Workflow Services, where we can map the WCF service contracts to a workflow, is this the right way to design the applications? Is EF 1.0 business entities can be used in n-tier apps without sacrificing the tracking changes in the entities? Is there a sample reference application available to look? Thanks.

• Why does GetTextFace always return "system"?

  - by user545142

  I am trying to get the font of controls in other applications. When I try WM_GETFONT, it returns 0. This my code: [DllImport("User32.DLL")] public static extern IntPtr SendMessage(IntPtr hWnd, int Msg, int wParam, int lParam); IntPtr fx = SendMessage(button1.Handle, 0x31, 0, 0); When I use GetTextFace with a button, it always returns "system". This is my code: StringBuilder Buff = new StringBuilder(256); IntPtr dc = GetDCEx(button1.Handle, IntPtr.Zero, DeviceContextValues.Window |DeviceContextValues.Cache | DeviceContextValues.ClipSiblings | DeviceContextValues.IntersectRgn); IntPtr hfont = GetTextFace(dc, 256, Buff); Of course I'm sure I changed the font type. How can I solve this problem? I am using C# under Windows 7.

• Can silverlight detect or communicate across browser instances?

  - by isolatedIterator

  User starts up a silverlight application in their browser by navigating to a given URL. User then opens another browser and starts up the same silverlight application by navigating to the same URL. Can the second instance of the application detect that there is already an instance running on the same computer? Can it detect itself if both applications are running within the same browser instance? I would expect the answer to be 'no' but thought that i would ask it anyway. Otherwise i believe that i will have to setup a webservice and have each instance register itself and send requests to other instances from the same IP. does that sound reasonable?

• Browser application & local file system access

  - by Beyond HTML

  I want to enhance my browser-based web application with functionality that enables management of local files and folders. E.g. folder tree structures should be synchronized between local workstation and server via HTTP(S). I am aware of security-related limitations in browser-based applications. However, there are some techniques that "work around" these issues: Signed Java applets (full trust) .NET Windows Forms browser controls (no joke, that works. Just the configuration is horrible) ActiveX My question is: What do you use/suggest, both technology and implementation practice? Key requirement is that the installation process is as simple as possible. Thanks for your opinions!
