  • VNC application/terminal server

    - by sebastian nielsen
    Which software should I use, if I want to set up a linux VNC terminal server that works in this way: The VNC server should be able to accept up to X simultanous connections on the same port 5900. The VNC server should use 640x480 on 8 or 16bit color. When the VNC server receives the connection, it should start a new "session" for a user, and auto-launch a specific linux application for that user. If the application is killed, crashes, or is exited in any way, user should be disconnected (kicked) from server. If the user disconnect, the application should be killed in a "graceful way", that allows the application to cleanup. (There should be no way to "pick up" a old session) Any ideas?

  • Deployed Web Application Requests for User Name and Password

    - by user43175
    Deployed Web Application Requests for User Name and Password I recently deployed a .NET web application into the server. Authentication mode is set to Windows (since the application is accessible only to Intranet users. Testing some machines, the application loads up properly. For some machines, a logon dialog window appears asking for User Name or Password. These dialog windows are those that you also normally see when you are trying to log into a Windows domain. Any idea why this happens randomly? Thanks.

  • For a .NET winforms datagridview I would like a combobox column to have a different set of values for each row.

    - by Seth Spearman
    Hello, I have a DataGridView that I am binding to a POCO. I have the databinding working fine. However, I have added a combobox column that I want to be different for each row. Specifically, I have a grid of purchased items, some of which have sizes (like Adult XL, Adult L) and other items are not sized (like Car Magnet.) So essentially what I want to change is the DATA SOURCE for a combobox column in the data grid. Can that be done? What event can I hook into that would allow me to change properties of certain columns FOR EACH ROW? An acceptable alternative is to change a property when the user clicks or tabs into the row. What event is that? Seth EDIT I need more help with this question. With Triduses help I am SO close but I need a bit more information. First, per the question, is the CellFormatting event really the best/only event for changing the DataSource for a combo box column. I ask because I am doing something rather resource/data intensive, not merely formatting the cell. Second, the cellformatting event is being called just by having the mouse hover over the cell. I tried to set the FormattingApplied property inside my if-block and then I check for it in the if- test but that is returning a weird error message. My ideal situation is that I would apply change the data source for the combo box once for each row and then be done with it. Finally, in order to set the data source of the combobox colunm I have to be able to cast the Cell inside my if block to a type of DataGridViewComboBoxColumn so that I can fill it with rows or set the datasource or something. Here is the code I have right now. Private Sub ProductsDataGrid_CellFormatting(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellFormattingEventArgs) Handles ProductsDataGrid.CellFormatting If e.ColumnIndex = ProductsDataGrid.Columns("SizeDGColumn").Index Then ' AndAlso Not e.FormattingApplied Then Dim product As LeagueOrderProductInfo = DirectCast(ProductsDataGrid.Rows(e.RowIndex).DataBoundItem, LeagueOrderProductInfo) Dim sizes As LeagueOrderProductSizeList = product.ProductSizes sizes.RemoveSizeFromList(_parentOrderDetail.SizeID) 'WHAT DO I DO HERE TO FILL THE COMBOBOX COLUMN WITH THE sizes collection. End If End Sub Please help. I am completely stuck and this task item should have taken an hour and I am 4+ hours in now. BTW, I am also open to resolving this by taking a completely different direction with it (as long as I can be done quickly.) Seth

  • why develop in windows/desktop application?

    - by Alexander
    Just wondering what your comments are regarding the current trend as everything is moving to the web or even the cloud. The significance of an OS or desktop application is getting less attention than web application. So to those folks out there who still develop windows applications, such as WPF. Why still do it? Why not move to web programming? Silverlight instead for example...

  • Terminal Server 2008: Installing 16-bit Application (FoxPro 2.6)

    - by JohnyD
    I have one physical Windows 2008 R2 server running Hyper-V. Running under Hyper-V I have a virtual Windows Server 2008 R2 server running Remote Desktop Services (Terminal Services). I'm preparing my applications using the "Install Application on Remote Desktop..." control panel app. So far so good. However, I am now trying to install FoxPro 2.6 which is a 16-bit windows application. When I try to install it I receive the message: "The version of this file is not compatible with the version of Windows you're running. Check your computer's system information to see whether you need an x86 (32-bit) or x64 (64-bit) version of the program, and then contact the software publisher". Is there any way around this? I'm in the middle of a large migration to thin-clients and foxpro 2.6, while it won't be around forever, is a very integral application for our data-entry personnel. How can I get this to work? Thanks in advance!

  • Learning AngularJS by Example – The Customer Manager Application

    - by dwahlin
    I’m always tinkering around with different ideas and toward the beginning of 2013 decided to build a sample application using AngularJS that I call Customer Manager. It’s not exactly the most creative name or concept, but I wanted to build something that highlighted a lot of the different features offered by AngularJS and how they could be used together to build a full-featured app. One of the goals of the application was to ensure that it was approachable by people new to Angular since I’ve never found overly complex applications great for learning new concepts. The application initially started out small and was used in my AngularJS in 60-ish Minutes video on YouTube but has gradually had more and more features added to it and will continue to be enhanced over time. It’ll be used in a new “end-to-end” training course my company is working on for AngularjS as well as in some video courses that will be coming out. Here’s a quick look at what the application home page looks like: In this post I’m going to provide an overview about how the application is organized, back-end options that are available, and some of the features it demonstrates. I’ve already written about some of the features so if you’re interested check out the following posts: Building an AngularJS Modal Service Building a Custom AngularJS Unique Value Directive Using an AngularJS Factory to Interact with a RESTful Service Application Structure The structure of the application is shown to the right. The  homepage is index.html and is located at the root of the application folder. It defines where application views will be loaded using the ng-view directive and includes script references to AngularJS, AngularJS routing and animation scripts, plus a few others located in the Scripts folder and to custom application scripts located in the app folder. The app folder contains all of the key scripts used in the application. There are several techniques that can be used for organizing script files but after experimenting with several of them I decided that I prefer things in folders such as controllers, views, services, etc. Doing that helps me find things a lot faster and allows me to categorize files (such as controllers) by functionality. My recommendation is to go with whatever works best for you. Anyone who says, “You’re doing it wrong!” should be ignored. Contrary to what some people think, there is no “one right way” to organize scripts and other files. As long as the scripts make it down to the client properly (you’ll likely minify and concatenate them anyway to reduce bandwidth and minimize HTTP calls), the way you organize them is completely up to you. Here’s what I ended up doing for this application: Animation code for some custom animations is located in the animations folder. In addition to AngularJS animations (which are defined using CSS in Content/animations.css), it also animates the initial customer data load using a 3rd party script called GreenSock. Controllers are located in the controllers folder. Some of the controllers are placed in subfolders based upon the their functionality while others are placed at the root of the controllers folder since they’re more generic:   The directives folder contains the custom directives created for the application. The filters folder contains the custom filters created for the application that filter city/state and product information. The partials folder contains partial views. This includes things like modal dialogs used in the application. The services folder contains AngularJS factories and services used for various purposes in the application. Most of the scripts in this folder provide data functionality. The views folder contains the different views used in the application. Like the controllers folder, the views are organized into subfolders based on their functionality:   Back-End Services The Customer Manager application (grab it from Github) provides two different options on the back-end including ASP.NET Web API and Node.js. The ASP.NET Web API back-end uses Entity Framework for data access and stores data in SQL Server (LocalDb). The other option on the back-end is Node.js, Express, and MongoDB.   Using the ASP.NET Web API Back-End To run the application using ASP.NET Web API/SQL Server back-end open the .sln file at the root of the project in Visual Studio 2012 or higher (the free Express 2013 for Web version is fine). Press F5 and a browser will automatically launch and display the application. Using the Node.js Back-End To run the application using the Node.js/MongoDB back-end follow these steps: In the CustomerManager directory execute 'npm install' to install Express, MongoDB and Mongoose (package.json). Load sample data into MongoDB by performing the following steps: Execute 'mongod' to start the MongoDB daemon Navigate to the CustomerManager directory (the one that has initMongoCustData.js in it) then execute 'mongo' to start the MongoDB shell Enter the following in the mongo shell to load the seed files that handle seeding the database with initial data: use custmgr load("initMongoCustData.js") load("initMongoSettingsData.js") load("initMongoStateData.js") Start the Node/Express server by navigating to the CustomerManager/server directory and executing 'node app.js' View the application at http://localhost:3000 in your browser. Key Features The Customer Manager application certainly doesn’t cover every feature provided by AngularJS (as mentioned the intent was to keep it as simple as possible) but does provide insight into several key areas: Using factories and services as re-useable data services (see the app/services folder) Creating custom directives (see the app/directives folder) Custom paging (see app/views/customers/customers.html and app/controllers/customers/customersController.js) Custom filters (see app/filters) Showing custom modal dialogs with a re-useable service (see app/services/modalService.js) Making Ajax calls using a factory (see app/services/customersService.js) Using Breeze to retrieve and work with data (see app/services/customersBreezeService.js). Switch the application to use the Breeze factory by opening app/services.config.js and changing the useBreeze property to true. Intercepting HTTP requests to display a custom overlay during Ajax calls (see app/directives/wcOverlay.js) Custom animations using the GreenSock library (see app/animations/listAnimations.js) Creating custom AngularJS animations using CSS (see Content/animations.css) JavaScript patterns for defining controllers, services/factories, directives, filters, and more (see any JavaScript file in the app folder) Card View and List View display of data (see app/views/customers/customers.html and app/controllers/customers/customersController.js) Using AngularJS validation functionality (see app/views/customerEdit.html, app/controllers/customerEditController.js, and app/directives/wcUnique.js) More… Conclusion I’ll be enhancing the application even more over time and welcome contributions as well. Tony Quinn contributed the initial Node.js/MongoDB code which is very cool to have as a back-end option. Access the standard application here and a version that has custom routing in it here. Additional information about the custom routing can be found in this post.

  • How does the PPA fit into the scenario of publishing an application to the Ubuntu Software Center?

    - by Mridang Agarwalla
    I've been going through docs for the past couple of hours but I haven't understood what the PPA is? I have a cross-platform Java application that I'd like to publish to the Ubuntu Software Center. My application is open-source and I'm using Github. Apparently, publishing applications to the store isn't as simple as uploading a deb package - am I right? I need to create an account on Launchpad and put all my code there. I don't intend to move from Git to Bzr merely for the sake of publishing to the app store but luckily, one is able to set up source-code mirroring from Github to Launchpad. Since my application is still very premature, it'll have updates fairly often. When I build my application on my machine, do I simply go my Ubuntu App Developer page and upload the new DEB package or do they build my application from source? What exactly is the PPA for? I don't think I'll need too many of the Launchpad features so I'd like to stick to Github if possible. (Publishing for Ubuntu really isn't trivial. I can see why there are so many developers out there who haven't published their applications to the Ubuntu Software Center. Publishing an Android applications has been the easiest so far.)

  • Is it possible for an application (written in Mono C#) to run a console command?

    - by Razick
    I am wondering if a Mono C# application can somehow run a terminal command. For example, could the user give the program his or her password and then have the application run sudo apt-get install application-name (console requests password) password (console requests confirmation) y Preferably, this would be done without actually opening a terminal visible to the user, so that the application could provide the necessary feedback and manage the whole operation cleanly with as little user interaction as possible. Is there a way to do that? Let me know if clarification is needed. Thank you!

  • Why the Ubuntu App Developer website is not showing content about development for desktop?

    - by Zignd
    Looks like they removed every content that is not related with development for desktop. For example when you click in "Get Started" tab there is only information about the Ubuntu Touch and its SDK, when you click on "Resources" tab and then on "Programming languages" you only see C++, JavaScript and QML (no Python, Java, Mono, etc). You also can't find any information about Quickly, try clicking on "Quicky" at "Resources" in the website bottom and you will see a "Page not found" error. Is the site under maintenance or something else?

  • How to use Application Verifier to find memory leaks

    - by Patrick
    I want to find memory leaks in my application using standard utilities. Previously I used my own memory allocator, but other people (yes, you Neil) suggested to use Microsoft's Application Verifier, but I can't seem to get it to report my leaks. I have the following simple application: #include <iostream> #include <conio.h> class X { public: X::X() : m_value(123) {} private: int m_value; }; void main() { X *p1 = 0; X *p2 = 0; X *p3 = 0; p1 = new X(); p2 = new X(); p3 = new X(); delete p1; delete p3; } This test clearly contains a memory leak: p2 is new'd but not deleted. I build the executable using the following command lines: cl /c /EHsc /Zi /Od /MDd test.cpp link /debug test.obj I downloaded Application Verifier (4.0.0665) and enabled all checks. If I now run my test application I can see a log of it in Application Verifier, but I don't see the memory leak. Questions: Why doesn't Application Verifier report a leak? Or isn't Application Verifier really intended to find leaks? If it isn't which other tools are available to clearly report leaks at the end of the application (i.e. not by taking regular snapshots and comparing them since this is not possible in an application taking 1GB or more), including the call stack of the place of allocation (so not the simple leak reporting at the end of the CRT) If I don't find a decent utility, I still have to rely on my own memory manager (which does it perfectly).

  • Traditional ASP.NET application in subdirectory of an MVC application

    - by David
    Windows Server 2003, IIS6. We're trying to deploy a non-MVC ASP.NET web application as a subdirectory of an MVC application. However the ASP.NET application in the subdirectory is failing with the message "Could not load file or assembly 'System.Web.Mvc, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified." which is bizarre because it's not an MVC application.

  • How to create a stand alone command line application with Node.js

    - by Fab
    I'm trying to find a way to use a command line nodejs application that I created on a computer without node.js installed. In other words how to package my application with node.js inside, in order to avoid the users to have node.js already installed. The tipical use case is: I run the application and the application works using the node core that is provide with the application (or the application checks if there is node.js installed, and if not it donwload and install it automatically). Do you have any idea?

  • Bare-metal virtualisation for the desktop

    - by Andrew Taylor
    Hi, Does anyone have any knowledge about bare-metal virtualisation products? I'm interested in building a new desktop machine for home, I've been looking at the Intel Quad Core processors and I'd like to put 8GB of RAM in there, but, it got me thinking about making the most out of the available resources. I thought if I could get a good 64bit machine, put some bare-metal virtualisation on, then have a primary system, I'd also be able to bring up some extra virtualised systems as and when I needed. I know most of the bare metal systems are designed for the server market, but, is there anything out there that works well for a desktop. What are the caveats? I presume I won't be able to make the most out of any video cards I could buy, what about just getting a decent screen resolution, will this be a problem? I run a single 24" screen. What about DVD/CD writing, is this possible? I'd like to re-rip my CD collection, I was hoping the quad 64Bit goodness would help me out with the encoding. I currently use a Mac and couldn't go back to windows so that leaves Linux, I was thinking a primary OS of ubuntu. Does this make a difference? Thanks Andrew

  • Advantages of Using Linux as primary developer desktop

    - by Nick N
    I want to get some input on some of the advantages of why developers should and need to use Linux as their primary development desktop on a daily basic as opposed to using Windows. This is particulary helpful when your Dev, QA, and Production environments are Linux. The current analogy that I keep coming back to is. If I build my demo car as a Ford Escort, but my project car is a Ford Mustang, it doesn't make sense at all. I'm currently at an IT department that allows dual boot with Windows and Linux, but some run Linux while the vast majority use Windows. Here's several advantages that I've came up with since using Linux as a primary desktop. Same Exact operating system as Dev, QA, and Production Same Scripts (.sh) instead of maintaining (.bat and *.sh). Somewhat mitigated by using cygwin, but still a bit different. Team learns simple commands such as: cd, ls, cat, top Team learns Advanced commands like: pkill, pgrep, chmod, su, sudo, ssh, scp Full access to installs typically for Linux, such as RPM, DEB installs just like the target environments. The list could go on and on, but I want to get some feedback of anything that I may have missed, or even any disadvantages (of course there are some). To me it makes sense to migrate an entire team over to using Linux, and using Virtual Box, running Windows XP VM's to test functional items that 95% of most of the world uses. This is similar but a little different thread going on here as well. link text

  • Change workarea size of Linux desktop

    - by nonoitall
    I'm trying to write a taskbar/panel for Linux (like fbpanel or pypanel) using GTK# and am a little hung up. I've created a Gtk.Window to act as the panel and positioned/resized it appropriately. I've also set its WindowTypeHint to Dock so that it remains on top of other windows. So far it 'looks' like a panel. However, if the panel is running and I maximize another window, that window fills the whole desktop - meaning the bottom portion of the window is covered up by my panel. I've gathered that I probably need to change the desktop's workarea. How can I go about doing this in C#? (Preferably using GTK#, but I don't mind using interop if it's necessary.) As a bit of a side point, I'm curious if anyone knows how I would go about 'informing' the window manager about where applications' taskbar buttons are. (For example, if the window manager wants to animate the minimize action so that the window shrinks down to its button on the taskbar, how do I let the window manager know where that button is on the taskbar?)

  • How to prevent any files from being copied onto the Desktop?

    - by Kaushik Gopal
    Gentlepeeps, Is there any solution to prevent copying of files onto the desktop? My folks and i currently have one super-common-comp in our place. And when all of the laptops are busy, we tend to do some quick surfing on this comp. I prefer to keep things freakishly organized in this comp and one thing i hate is having those off-shoot irritating forwarded downloads on my desktop. Is there some way to restrict files from being copied onto the desktop? I tried making the administrator user's desktop folder as read-only :P . That doesn't solve the problem. Any other ideas/software/solutions? cheers.
