    Default Version 3.1 for DataFlex 20.0 Released

    We are happy to announce the release of version 3.1 of the DataFlex Graphics Library. With your Data Access Global Account ID you can download this library and demo application from

    NOTE: This version requires an installed DataFlex 20.0 product and is licensed for use with DataFlex 20.0.

    The download is an installer that installs the library and optionally up to 3 example workspaces. One example workspace is for the DataDemo application based on the DataFlex embedded database, one for an MSSQL database (and the installer creates a database if you indicate this) and one workspace that is not databound and shows the use of the library to resize images, shows shapes etc.

    The help file has been extended and reformatted and can be used together with DataFlex 20.0
