4D v11 SQL Release 2

Tue, 2008-06-24 (All day)

In addition to the availablility of 4D Server v11 SQL as of v11.2, stunning new interface features bring enhanced software ergonomics to developers and end-users alike, with in-depth integration of standards like JavaScript and SVG (scalable vector graphics). The new Web Area object gives developers the ability to incorporate HTML content, PDF files, Office documents, QuickTime movies, and Flash animations directly into their solutions.

Does 4D for Flex require modifying existing code?

No server-side code is necessary, but you'd better add some security control in the new On SQL Authentication database method.

What's the minimum version of 4D required to use 4D for Flex?

The minimum version of 4D required is 4D v11 SQL Release 2 (11.2)

What's required for development with 4D for Flex?

Apart from a 4D SQL server, you need the Flex SDK.

 

You can get if for free from Adobe's site (http://www.adobe.com/products/flex/) and use it with the command-line, or use the commercial IDE Flex Builder provided by Adobe.

What's the difference between 4D for Flex and DAX?

They both target developing RIAs for a 4D Server. But, they really follow two different schemes:


4D for Flex works in a connected mode, without any component on Server side. The communication between the client and the Server relies on a proprietary SQL protocol (same as the one used for ODBC support for 4D SQL), so it requires opening a special port on firewalls for allowing communication.

Can you lock records in 4D for Flex?

You can use the SELECT FOR UPDATE feature. Please see the manual for more information.

Does 4D for Flex require 4D Server?

Not for development, but for deployment, yes.
