Working with the latest Internet and Web technologies, such as JavaScript, JSON, JSONP and Ajax, to name but a few, we are always finding solutions to software problems that we feel may also benefit others. So, rather than keep valuable knowledge to ourselves, we have dedicated this part of our website to publishing some of our sample applications and example code here.
In addition to the sample applications and example code here, you may also like to view our blog articles, white papers and presentations available from the Company menu heading. If you are specifically searching for DataFlex related code examples, we also recommend that you visit DataFlex.wiki and use the search facility there, or refer to the DataFlex Online help.
