  • Where to go after Informix 4GL?

    - by Chris Harris
    We have a large homegrown ERP system written in Informix 4GL. Currently we are running on old Sun hardware, Solaris 8, and a ten year old version of 4GL and Informix. We need to move on, and one option obviously is to get the latest versions of 4GL & Informix, installed on new hardware (probably Linux/Intel). However I believe there are options for migrating 4GL programmes to other development platforms. Does anyone have experience of that? If so, what platforms, how did it go, what are the pros and cons?

  • Progress 4GL and DB to Oracle and cloud

    - by llaszews
    Getting from client/server based 4GLs and databases where the 4GL is tightly linked to the database to Oracle and the cloud is not easy. The least risky and expensive option (in the short term) is to use the Progress OpenEdge DataServer for Oracle: Progress OpenEdge DataServer This eliminates the need to have to migrate the Progress 4GL to Java/J2EE. The database can be migrated using SQLWays Ispirer: Ispirer SQLWays ProgressDB migrations tool The Progress 4GL can remain as is. In order to get the application on the cloud there are a few approaches: 1. VDI - Virtual Desktop is a way to put all of the users desktop in a centralized environment off the desktop. This is great in cases where it is just not one client/server application that the user needs access too. In many cases, users will utilize MS Access, MS Excel, Crystal Reports and other tools to get at the Progress DB and other centralized databases. Vmware's acquistion of Wanova shows how VDI is growing in usage. Citrix is the 800 pound gorilla in the VDI space with Citrix WinFrame (now called XenDesktop). Oracle offers a VDI solution that Oracle picked up when it acquired Sun. 2. Hypervisor Server Virtualization - Of course you can place applications written in client/server languages like Progress 4GL buy using server virtualization from Oracle, VMWare, Microsoft, Citrix and others. 3. Microsoft Remote Desktop Services (aka: Terminal Services Client) The entire idea is to eliminate all the client/server desktop devices and connections which require desktop software and database drivers. A solution to removing database drivers from the desktop is to use DataDirect SQLLink

  • Delphi connection to OpenEdge Progress-4GL Database

    - by Cesar Marrero
    Folks: Has anyone had success connecting to a Progress-4GL database with Delphi?   I've been unable to establish any connection with the ODBC driver provided by the vendor (Progress OpenEdge 10.1C Driver). I've entered (what I believe are) the right parameters, but keep on getting an error whenever I test the connection: "[DataDirect][ODBC Progress OpenEdge Wire Protocol driver] Socket closed." Background: I've been tasked to re-design a 13-year-old application, but the original programmer did not provide any supporting documents, passwords, configuration setup, etc. (I'm on my own)!   To make things worse, online help and useful documentation about Progress is scarce (I had never heard about this database until now). I want to examine the existing data, maybe create an ERD to familiarize myself with the schema, but I can't even access the data outside of the OpenEdge code. Any help is appreciated!

  • Stephen Forte visits IDEP Foundation Recipient of our post-tsunami .NET Charity Auction

    Earlier this week I got an email from Stephen Forte saying he was in Bali and would love to meet the folks from IDEP Foundation.

  • Scrum Master Stephen Forte Teaches Agile Development, Silverlight and BI at GIDS 2010

    - by rajesh ahuja
    Great Indian Developer Summit 2010 – Gold Standard for India's Software Developer Ecosystem Bangalore, March 25, 2010: The author of several books on application and database development including Programming SQL Server 2008 and certified Scrum Master Stephen Forte is coming this summer to India's biggest summit for the developer ecosystem - Great Indian Developer Summit. At the summit, Stephen will conduct a workshop guaranteed to give attendees a jump start in taking a certified scrum master exam. Scrum, one of the most popular Agile project management and development methods, which is starting to be adopted at major corporations and on very large projects. After an introduction to the basics of Scrum like project planning and estimation, the Scrum Master, team, product owner and burn down, and of course the daily Scrum, Stephen will show many real world applications of the methodology drawn from his own experience as a Scrum Master. Negotiating with the business, estimation and team dynamics are all discussed as well as how to use Scrum in small organizations, large enterprise environments and consulting environments. Stephen will also discuss using Scrum with virtual teams and an off-shoring environment. He will then take a look at the tools we will use for Agile development, including planning poker, unit testing, and much more. On 20th April at the GIDS.NET Conference, Stephen will also conduct a series of sessions on Microsoft computing technologies. He will teach how to build data driven, n-tier Rich Internet Applications (RIA) with Silverlight 4.0. Line of business applications (LOB) in Silverlight 4.0 are easy by tapping the power of WCF RIA Services, the Silverlight Toolkit, and elevated out of browser support. Stephen's demo centric session will walk you through an example of building a LOB application with Silverlight 4.0. See how Silverlight and WCF RIA Services support domain logic, services, data binding, validation, server based paging, authentication, authorization and much more. Silverlight 4.0 means business. Silverlight runs C# and Visual Basic code, and so it seems natural that a business application might share some code between the Silverlight client and its ASP.NET Web server. You may want to run some code client-side for interactivity, but re-run that code on the server for security or reliability. This is possible, and there are several techniques you can use to accomplish this goal. In Stephen's second talk learn about the various techniques and their pros and cons. Some techniques work better in C#, others in VB. Still others are simpler with a little extra tooling or code-generation. Any serious Silverlight business application will almost certainly face this issue, and this session gets you going fast. In the third talk, Stephen will explain how to properly architect and deploy a BI application using a mix of some exciting new tools and some old familiar ones. He will start with a traditional relational transaction centric database (OLTP) and explore ways to build a data warehouse (OLAP), looking at the star and snowflake schemas. Next he will look at the process of extraction, transformation, and loading (ETL) your OLTP data into your data warehouse. Different techniques for ETL will be described and the various tradeoffs will be discussed. Then he will look at using the warehouse for reporting, drill down, and data analysis in Microsoft Excel's PowerPivot 2010. The session will round off by showing how to properly build a cube and build a data analysis application on top of that cube, and conclude by looking at some tools to help with the data visualization process.

    Windows Embedded : Microsoft adapte sa gamme d'OS embarqués à un secteur en forte expansion Riche d'opportunités pour les développeurs Dans la famille Windows, les noms de XP, Vista, 7, Server ou même Azure sont certainement plus connus que « Embedded ». Il faut dire que les déclinaisons embarquées de Windows sont à elles seules une gamme complète dans laquelle il peut être souvent assez difficile de s'y retrouver. Pourtant, les développeurs auraient tort de se décourager, tant les déclinaisons de Windows Embedded couvrent un nombre impressionnant de besoins allant du terminal mobile durci (lecteur de code barre avec écran par exemple) à la robotique en passant par les boîtiers multimédia...

  • Silverlight ViewBase in separate assembly - possible?

    - by Mark
    I have all my views in a project inheriting from a ViewBase class that inherits from UserControl. In my XAML I reference it thus: <f:ViewBase x:Class="Forte.UI.Modules.Configure.Views.AddNewEmployeeView" xmlns:f="clr-namespace:Forte.UI.Modules.Configure.Views" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" It works fine. Now I have moved the ViewBase to another project (so I can refernce it from multiple projects) so I reference it like: <f:ViewBase x:Class="Forte.UI.Modules.Configure.Views.AddNewEmployeeView" xmlns:f="clr-namespace:Forte.UI.Modules.Common.Views;assembly=Forte.UI.Modules.Common" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" This works fine when I run from the IDE but when I run the same sln from MSBuild it gives a warning: "H:\dev\ExternalCopy\Code\UI\Modules\Configure\Forte.UI.Modules.Configure.csproj" (default target) (10:12) - (ValidateXaml target) - H:\dev\ExternalCopy\Code\UI\Modules\Configure\Views\AddNewEmployee\AddNewEmployeeView.xaml(1,2,1,2): warning : The tag 'ViewBase' does not exist in XML namespace 'clr-namespace:Forte.UI.Modules.Common.Views;assembly=Forte.UI.Modules.Common'.
