A common theme that we run into with our customers is the need to deal with characters from different language groups. We've found that this is a very confusing topic for many users who don't understand the interaction of the pieces.  In this article, we explore how all this hangs together and how it relates to Providers for MultiValue .NET, COM and Java connectivity.

Lots of customers have subroutines that have been developed to provide specific functionality.  With the FusionWare mvLynx Direct Data Access Server you can quickly and easily make these subroutines accessible.  Once exposed, these can be called from .NET, Java, PHP and many more environments.

We will start by giving you an example subroutine and calling it from a test harness from TCL.  Then we will show how we expose it for consumption.  Next we'll actually call it, in this case, from a .NET console application.  Finally, we'll talk about some gotchas and ways to work around them.

We take the automapped ORDERS file from the Demo account on Unidata for Windows and pull the single values, multi values and sub values into three different spreadsheets, named Orders, OrderLines and Options.

This post was modified May 4th, 2011 to reflect initial steps to take for customers who don't have Microsoft Office Tools for Visual Studio.  It now works for just Microsoft Excel 2007 or 2010.

In this installment, we will be accessing the RESTful web services we created in the previous installment from an iPhone App.  For the App, we will take an example app from the book “iPhone SDK Development” by The Pragmatic Programmers”, available at

Note that the same code we will be providing below would also be used for an iPod Touch or an iPad App.

In this post we take a look at some of the new and upcoming technologies that are already changing our technical landscape, and that you will find yourself dealing with soon, if not already!

REST services are much easier to use from many environments like Mobile devices and many web-based programming environments, so in this post, we'll look at extending our DAL with RESTful services.

In previous posts, we've looked at multiple ways to access our example SALESORDER MultiValue file, including Mapping itaccessing it using MultiValue Dictionaries and using MV/BASIC stored procedures.  In this post, we look at some mechanisms provided by the FusionWare mvLynx Managed Provider for accessing raw multivalued data and manipulating it.

In this installment we take a look at some of the types of application integration that you may need to do, and how we provide the Unlock Codes for these.

There are two ways to do updates.  If you are using a mapped view of a MultiValue file, and make changes to the DataTable objects in the DataSet that we return when using the FWDataAdapter to “Fill” the DataSet, then you can use the FWDataAdapter Update method to automatically do this update using optimistic locking.  For those who want more granular control, and who want to do edit checks and update multiple MultiValue files, we’ll also look at a very simple stored procedure for updating a single value.

In our previous installment we looked at the Unlock Codes for MultiValue Mobile Computing.

In this installment we are going to look at how you can integrate your MultiValue data and logic with Cloud Computing platforms.
