Don't lose your investment in Crystal Reports.

For years, DataFlex developers used Crystal Reports as their embedded reporting tool. And for good reasons. It was and still is, the best report development tool in the market today. However,  DataFlex developers were stranded in Crystal Reports XI as support for Crystal Reports for DataFlex was discontinued.  Redeveloping these reports into another tool is a major undertaking and easy. This becomes especially a challenge if you are trying to adopt a tool not as feature-rich as Crystal Reports.

With Flex2Crystal  you don't have to do any of that.  It enables you to upgrade to the latest versions of Crystal, without needing to change your existing embedded reports.  For developers who want to continue to use Crystal Reports with the newest versions of DataFlex, or develop new sophisticated embedded reports,   Flex2Crystal is the only solution.

We took our existing code out of our Windows application, wrote a utility to replace 3 lines of code on each report file, tossed in your procedure, and done! Crystal Reports works in our web application, and the whole thing took only an hour to do!”
