  • web application or wep portal

    - by klo
    as title said differences between those 2. I read all the definition and some articles, but I need information about some other aspects. Here is the thing. We want to build a web site that will contain: site, database, uploads, numerous background services that would have to collect information from uploads and from some other sites, parse them etc...I doubt that there are portlets that fits our specific need so we will have to make them our self. So, questions: 1. Deployment ( and difference in cost if possible), is deploying portals much more easier then web app ( java or .net) 2. Server load. Does portal consume much of server power ( and can you strip portal of thing that you do not use) 3. Implementation and developing of portlets. Can u make all the things that you could have done in java or .net? 4. General thoughts of when to use portals and when classic web app. Tnx all in advence...

  • Mac: How to create a .app from a Mono application

    - by Svish
    I have downloaded the zip version of KeePass. To run it I have to open the Terminal, go to wherever I unzipped it and run mono KeePass.exe. Is there someway I can take all the files in that zip file and that command and bundle them up so I get a KeePass.app I can stick in my Applications folder that can more easily be run?

  • Windows 7 - problems launching default application

    - by Chris W
    Just built up a new W7 PC. I've noticed some strange issues with launching default applications. I've got Visual Studio & SQL Server Management Studio set run as administrator when launched. If i double click a .sql file SSMS opens ok but the file itself does not get loaded. If I do the same with a .sln then I get nothing at all from Visual Studio. For the latter I presume the UAC prompt is hidden somewhere waiting for me to say it's ok to launch the app but i've no idea what's happening with SSMS. Is this a W7 bug or are there some settings somewhere that I can tweak to improve this behaviour?

  • problem with launching application from other os on a multi boot system

    - by Nrew
    What do I do so that I could launch firefox on windows 7 if it is installed on windows xp. I tried going to the drive where it is installed. And launch firefox from there but the firefox that is installed on windows 7 keeps on launching. I even changed the firefox.exe into something different and cleaned the registry using tune up utilites but still don't work. what do I do.

  • application that copies all links in a web page

    - by user23950
    I have to download something and those 100+ links to megaupload are all in the same webpage. Do you know of a better way of copying those links instead of copy and pasting them one by one? So that it will accumulate all the links, or portion of the links that I want to get and copy it all in the clipboard then just paste it on the download manager. For windows xp or 7

  • Team Foundation Server 2012 Build Global List Problems

    - by Bob Hardister
    My experience with the upgrade and use of TFS 2012 has been very positive. I did come across a couple of issues recently that tripped things up for a while. ISSUE 1 The first issue is that 2012 prior to Update 1 published an invalid build list item value to the collection global list. In 2010, the build global list, list item value syntax is an underscore between the build definition and the build number. In the 2012 RTM this underscore was replaced with a backslash, which is invalid.  Specifically, an upload of the global list fails when the backslash is followed at some point by a period. The error when using the API is: <detail ExceptionMessage="TF26204: The account you entered is not recognized. Contact your Team Foundation Server administrator to add your account." BaseExceptionName="Microsoft.TeamFoundation.WorkItemTracking.Server.ValidationException"><details id="600019" http://schemas.microsoft.com/TeamFoundation/2005/06/WorkItemTracking/faultdetail/03"http://schemas.microsoft.com/TeamFoundation/2005/06/WorkItemTracking/faultdetail/03" /></detail> when uploading the global list via the process editor the error is: This issue is corrected in Update1 as the backslash is changed to a forward slash. ISSUE 2 The second issue is that when upgrading from 2010 to 2012, the builds in 2010 are not published to the 2012 global list.  After the upgrade the 2012 global lists doesn’t have any builds and only builds run in 2012 are published to the global list. This was reported to the MSDN forums and Connect. To correct this I wrote a utility to pull all the builds and recreate the builds global list for each project in each collection.  This is a console application with a program.cs, a globallists.cs and a app.config (not published here). The utility connects to TFS 2012, loops through the collections or a target collection as specified in the app.config. Then loops through the projects, the build definitions, and builds.  It creates a global list for each project if that project has at least one build. Then it imports the new list to TFS.  Here’s the code for program and globalists classes. Program.CS using System; using System.Collections.Generic; using System.Linq; using System.Text; using Microsoft.TeamFoundation.Framework.Client; using Microsoft.TeamFoundation.Framework.Common; using Microsoft.TeamFoundation.Client; using Microsoft.TeamFoundation.Server; using System.IO; using System.Xml; using Microsoft.TeamFoundation.WorkItemTracking.Client; using System.Diagnostics; using Utilities; using System.Configuration; namespace TFSProjectUpdater_CLC { class Program { static void Main(string[] args) { DateTime temp_d = System.DateTime.Now; string logName = temp_d.ToShortDateString(); logName = logName.Replace("/", "_"); logName = logName + "_" + temp_d.TimeOfDay; logName = logName.Replace(":", "."); logName = "TFSGlobalListBuildsUpdater_" + logName + ".log"; Trace.Listeners.Add(new TextWriterTraceListener(Path.Combine(ConfigurationManager.AppSettings["logLocation"], logName))); Trace.AutoFlush = true; Trace.WriteLine("Start:" + DateTime.Now.ToString()); Console.WriteLine("Start:" + DateTime.Now.ToString()); string tfsServer = ConfigurationManager.AppSettings["TargetTFS"].ToString(); GlobalLists gl = new GlobalLists(); //replace this with the URL to your TFS instance.

  • Different Versions of an application in same java application server

    - by Cem
    Hi, We are utilizing citrix netscalar with more than 20 glassfish java application servers. Unfortunately we have to remove previous application before deploying a new version of it since we have same context for these two different application. This error-prone process leads some problems due to lack of attention in builds or other problems. In an urgent case, we simply want to redirect to all traffic to previous application. What is the best practice to run different version of an application in a substantial number of servers in same time? Thanks

  • Hosting and scaling of a facebook application on cloud?

    - by DhruvPathak
    We would be building a facebook application in django(Python), but still not sure of where to host it economically,and with a good provision to scale in case the app gets viral. Some details about the app: i) Would be HTML based like a website,using django as a framework. ii) 100K is the number of expected pageviews in a day,if the app is viral. iii) The users will not generate any media content,only some database data will be generated by them. It would be great if someone with more experience can guide on following points: A) Hosting on google app engine or Amazon EC2 or some other cloud like RackSpace : Preferable points found in AppEngine were ease of deployment,cost effectiveness and easy scaling. For EC2: Full hold of the virtual machine,Amazon NoSQL and RDMBS database services in case we decide to use them. B) Does backend technology affect monthly cost ? eg. would CPU and memory usage difference of Django over , for example , PHP framework like CodeIgnitor really make remarkable difference in running costs. ( Here is the article that triggered this thought process : http://journal.dedasys.com/2010/01/12/rough-estimates-of-the-dollar-cost-of-scaling-web-platforms-part-i#comments) C) Does something like Heroku , which provides additional services over Amazon EC2, prove to be better than raw cloud management ? It is not that we are trying for premature scaling, we just want to have a good start so that we are ready to handle unpredicted growth and scale.

  • few basic questions on webhosting (namservers & dns records)

    - by claws
    I bought a domain name on name.com & I want to use free webhosting on 110mb.com By default name.com integrates services of Google apps. Name server entries are ns1.name.com ns2.name.com ns3.name.com ns4.name.com When I registered on 110mb.com it gave me two addresses ns1.110mb.com ns2.110mb.com This is where I'm lost. The concept is that "Domain name should point to an address of the server where the website is hosted" right? Then why are these 4 entires by default. How exactly is it working? should I remove these 4 and then add 110mb.com servers or just append 110mb.com server addresses to name.com ones. I would like to use google apps. If I change these name server addresses would that remove google apps? I especially want to use email service of google. And I really don't understand what is CNAME, MX, or something something. I want to learn about these stuff & how it exactly works. When I search for webhost tutorial. I'm unable to find any fruitful results.

  • Developing a Cost Model for Cloud Applications

    - by BuckWoody
    Note - please pay attention to the date of this post. As much as I attempt to make the information below accurate, the nature of distributed computing means that components, units and pricing will change over time. The definitive costs for Microsoft Windows Azure and SQL Azure are located here, and are more accurate than anything you will see in this post: http://www.microsoft.com/windowsazure/offers/  When writing software that is run on a Platform-as-a-Service (PaaS) offering like Windows Azure / SQL Azure, one of the questions you must answer is how much the system will cost. I will not discuss the comparisons between on-premise costs (which are nigh impossible to calculate accurately) versus cloud costs, but instead focus on creating a general model for estimating costs for a given application. You should be aware that there are (at this writing) two billing mechanisms for Windows and SQL Azure: “Pay-as-you-go” or consumption, and “Subscription” or commitment. Conceptually, you can consider the former a pay-as-you-go cell phone plan, where you pay by the unit used (at a slightly higher rate) and the latter as a standard cell phone plan where you commit to a contract and thus pay lower rates. In this post I’ll stick with the pay-as-you-go mechanism for simplicity, which should be the maximum cost you would pay. From there you may be able to get a lower cost if you use the other mechanism. In any case, the model you create should hold. Developing a good cost model is essential. As a developer or architect, you’ll most certainly be asked how much something will cost, and you need to have a reliable way to estimate that. Businesses and Organizations have been used to paying for servers, software licenses, and other infrastructure as an up-front cost, and power, people to the systems and so on as an ongoing (and sometimes not factored) cost. When presented with a new paradigm like distributed computing, they may not understand the true cost/value proposition, and that’s where the architect and developer can guide the conversation to make a choice based on features of the application versus the true costs. The two big buckets of use-types for these applications are customer-based and steady-state. In the customer-based use type, each successful use of the program results in a sale or income for your organization. Perhaps you’ve written an application that provides the spot-price of foo, and your customer pays for the use of that application. In that case, once you’ve estimated your cost for a successful traversal of the application, you can build that into the price you charge the user. It’s a standard restaurant model, where the price of the meal is determined by the cost of making it, plus any profit you can make. In the second use-type, the application will be used by a more-or-less constant number of processes or users and no direct revenue is attached to the system. A typical example is a customer-tracking system used by the employees within your company. In this case, the cost model is often created “in reverse” - meaning that you pilot the application, monitor the use (and costs) and that cost is held steady. This is where the comparison with an on-premise system becomes necessary, even though it is more difficult to estimate those on-premise true costs. For instance, do you know exactly how much cost the air conditioning is because you have a team of system administrators? This may sound trivial, but that, along with the insurance for the building, the wiring, and every other part of the system is in fact a cost to the business. There are three primary methods that I’ve been successful with in estimating the cost. None are perfect, all are demand-driven. The general process is to lay out a matrix of: components units cost per unit and then multiply that times the usage of the system, based on which components you use in the program. That sounds a bit simplistic, but using those metrics in a calculation becomes more detailed. In all of the methods that follow, you need to know your application. The components for a PaaS include computing instances, storage, transactions, bandwidth and in the case of SQL Azure, database size. In most cases, architects start with the first model and progress through the other methods to gain accuracy. Simple Estimation The simplest way to calculate costs is to architect the application (even UML or on-paper, no coding involved) and then estimate which of the components you’ll use, and how much of each will be used. Microsoft provides two tools to do this - one is a simple slider-application located here: http://www.microsoft.com/windowsazure/pricing-calculator/  The other is a tool you download to create an “Return on Investment” (ROI) spreadsheet, which has the advantage of leading you through various questions to estimate what you plan to use, located here: https://roianalyst.alinean.com/msft/AutoLogin.do?d=176318219048082115  You can also just create a spreadsheet yourself with a structure like this: Program Element Azure Component Unit of Measure Cost Per Unit Estimated Use of Component Total Cost Per Component Cumulative Cost               Of course, the consideration with this model is that it is difficult to predict a system that is not running or hasn’t even been developed. Which brings us to the next model type. Measure and Project A more accurate model is to actually write the code for the application, using the Software Development Kit (SDK) which can run entirely disconnected from Azure. The code should be instrumented to estimate the use of the application components, logging to a local file on the development system. A series of unit and integration tests should be run, which will create load on the test system. You can use standard development concepts to track this usage, and even use Windows Performance Monitor counters. The best place to start with this method is to use the Windows Azure Diagnostics subsystem in your code, which you can read more about here: http://blogs.msdn.com/b/sumitm/archive/2009/11/18/introducing-windows-azure-diagnostics.aspx This set of API’s greatly simplifies tracking the application, and in fact you can use this information for more than just a cost model. After you have the tracking logs, you can plug the numbers into ay of the tools above, which should give a representative cost or in some cases a unit cost. The consideration with this model is that the SDK fabric is not a one-to-one comparison with performance on the actual Windows Azure fabric. Those differences are usually smaller, but they do need to be considered. Also, you may not be able to accurately predict the load on the system, which might lead to an architectural change, which changes the model. This leads us to the next, most accurate method for a cost model. Sample and Estimate Using standard statistical and other predictive math, once the application is deployed you will get a bill each month from Microsoft for your Azure usage. The bill is quite detailed, and you can export the data from it to do analysis, and using methods like regression and so on project out into the future what the costs will be. I normally advise that the architect also extrapolate a unit cost from those metrics as well. This is the information that should be reported back to the executives that pay the bills: the past cost, future projected costs, and unit cost “per click” or “per transaction”, as your case warrants. The challenge here is in the model itself - statistical methods are not foolproof, and the larger the sample (in this case I recommend the entire population, not a smaller sample) is key.

  • Get close window message in Hidden C# Console Application

    - by LexRema
    Hello everyone. I have a Windows Form that starts some console application in background(CreateNoWindow = rue,WindowStyle = ProcessWindowStyle.Hidden). Windows form gives me opportunity to stop the console application at any time. But I'd like to handle somehow the close message inside the console application. I tried to use hooking like: [DllImport("Kernel32")] public static extern bool SetConsoleCtrlHandler(HandlerRoutine handler, bool add); // A delegate type to be used as the handler routine // for SetConsoleCtrlHandler. public delegate bool HandlerRoutine(CtrlTypes ctrlType); // An enumerated type for the control messages // sent to the handler routine. public enum CtrlTypes { CTRL_C_EVENT = 0, CTRL_BREAK_EVENT, CTRL_CLOSE_EVENT, CTRL_LOGOFF_EVENT = 5, CTRL_SHUTDOWN_EVENT } private static bool ConsoleCtrlCheck(CtrlTypes ctrlType) { StaticLogger.Instance.DebugFormat("Main: ConsoleCtrlCheck: Got event {0}.", ctrlType); if (ctrlType == CtrlTypes.CTRL_CLOSE_EVENT) { // Handle close stuff } return true; } static int Main(string[] args) { // Subscribing HandlerRoutine hr = new HandlerRoutine(ConsoleCtrlCheck); SetConsoleCtrlHandler(hr, true); // Doing stuff } but I get the message inside ConsoleCtrlCheck only if the console window is created. But if window is hidden - I don't get any message. In my windows Form to close console application process I use proc.CloseMainWindow(); to send message to the console window. P.S. AppDomain.CurrentDomain.ProcessExit += CurrentDomain_ProcessExit; - also does not help Do you now other way to handle this situation? Thanks.

  • What java web application framework to use?

    - by frohiky
    One of the main products of my company is an Oracle Forms (and Reports) based application, that "needs" to be re-written in another technology. Why? Users want a more rich interface experience, and we want, preferably, to reduce costs with an open source application server. For this (HUGE) project, we intend to use a java web application framework, keep these points in mind: We have: hundreds of tables on our database (the ORM must be as flexible as possible); some logic which is (and will still be) based on PL/SQL procedures/functions/packages; a lot of CRUDs (the application itself is of an considerable size); a demand to work with/generate documents and workflows; an intranet based user environment; We want: to offer a RIA interface experience; use (if possible) an open source app server; a rapid (as possible) development framework; a somewhat mature framework with a "wise" roadmap (and a considerable community support); a MVC approach combined with JS or GWT widgets (e.g. Vaadin or SmartGWT); Well, in the past weeks I've read a lot of posts, Q&As on stackoverflow, and much more: Wicket, JSF, Tapestry, Grails, GWT, Struts2, Play, Spring, Seam, Echo, .... the list goes on! I've even researched about Alfresco..! The obvious question: Which one to use? At this time, any insight, recommendation, shared experience, advice will be more then welcome!

  • WPF : Access Application Resources when not referencing Shell from App.xaml

    - by CF_Maintainer
    I am beginner in WPF. My App.xaml looks like below app.xaml <Application x:Class="ContactManager.App" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <Application.Resources> <Color x:Key="lightBlueColor">#FF145E9D</Color> <SolidColorBrush x:Key="lightBlueBrush" Color="{StaticResource lightBlueColor}" /> </Application.Resources> I do not set the startupuri since I want to a presenter first approach. I do the following in app.xaml.cs protected override void OnStartup(StartupEventArgs e) { base.OnStartup(e); var appPresenter = new ApplicationPresenter( new Shell(), new ContactRepository()); appPresenter.LaunchView(); } I have a usercontrol called "SearchBar.xaml" which references "lightBlueBrush" as a staticResource. When I try to open "Shell.xaml" in the designer it tells me : The "shell.xaml" cannot be loaded at design time because it says it could not create an instance of type "SearchBar.xaml". When I debugged the devenv.exe using another visual studio instance it tells me that it does not have access to the Brush I created in app.resources. If one is doing a Presenter first approach, how does one access resources? I had this working when the startupURI was "Shell.xaml" and the startup event was not present. Any clues/ideas/suggestions. I am just trying to understand. Everything works as expected when I run the application just not @ design time.

  • Where to start with map application

    - by rfders
    Hi there, i'm trying to desing a new application which allow user see he/her current location on a custom map (office, university compus, etc). but actually i have a couple of question in my mind (i haven't designed this kind of application before). i'm wondering: How can i draw my own maps, what is the best option for it? there any format that i have to care of, there are any specification about it ? Once i have my custom map. how can i do to mapping a global position system with the local positions ? What are the tricks behing zoom on maps ? just differents layers with more or less informations and those layers changes on users demand ? If a whant to mark some specific points over the map, like a cafeteria, boss's office etc, how can i do that ? Sorry if my questions are too much generics and dumb, but i really need some clues about this topic because i don't have any idea how to design this kind of application as best as possible. and we don't whant to reinvent the wheel. I will appreciate any help that you can provide me in order to desing this application

  • DNS propogation question with name server change

    - by Brian
    The registrar I have is networksolutions.com, and for quite a while, the name servers were pointing to Site5.com, where hosting is for one of my domains. I wanted to bring DNS control back to networksolutions, so I pointed the name servers back to networksolutions and added in all my A records. However, I noticed that the site soon became unreachable. I'm curious as to why this happened? If the domain was pointing to either the old name servers or the new ones, it would still have the proper A records and whatnot. Is this because when I changed name servers, a request was made to delete them completely, and then the DNS servers worldwide have to wait for network solutions to send out the new ones or something? I was hoping this would be a switch with zero downtime, such as a normal A record change.

  • TFS 2010 Server Name Change

    - by PearlFactory
    So I thought I would  change the name of my machine so that the other devs can find the TFS server easily. TFS 2005 would use the cool cmd line util tfsadminutil.....alas he is now gone HERE Are the steps to complete Edit the web.config and is usually located on default install C:\Program Files\Microsoft Team Foundation Server 2010\Application Tier\Web Services\web.config <add key="applicationDatabase" value="Data Source=JUSTIN\SQLI01;Initial Catalog=Tfs_Configuration;Integrated Security=True;" /> Next step is to edit previous Solutions/Projects 1) Open the Solution file i.e ProductApp.sln 2) Edit the SccTeamFoundationServer URL under Global section i.e Change this to new name   If you have DB server on same machine ...you will need to go in and remove existing db user account assigned to the tfs DB Remove old [%machine_name%] value i.e Tuned_Dev_PC_12\Justin user from the above DBs No add the new Justin\Justin user account associated with the new machine name to the TFS & Reporing dbs ... dbo or the TFSADMIN & TFSEXEC roles either will do in this case. (or add both ) Now either ReApply user or add New account (remove old account i.e Tuned_Dev_PC_12\justin) If DB permisions are setup correctyly you will get a screen that looks like this   If it pauses or gets stuck you need to look back at the adding correct DB Perms to the i.e JUSTIN\Justin user account Also if your project is still complaining about old TFS name 1) Team\Connect new Team Foundation Server 2) Add\Remove TFS 3) Add New TFS Name  Once you have connected to the new TFS server Reload your project from TFS..this way it removes a lot of the bugs that hang around in the local project\solution This is similar to a VSS2005 and older fix Cheers ( eta about 60-90 mins so weigh up the the need vs payoff. ) Shutdown restart
