Migration of Delphi 7 to Delphi XE and want to replace existing BDE component.Migrating from one version to another could cause additional problems. It's not about the software used, but the database format. There is a known problem with Unicode support. It's known to cause a total mess with your databases. Before updating, I recommend checking Delphi and Unicode book released on the Embarcadero website. It should give you an insight regarding Delphi, Unicode support and migration. For the ADOConnection, it doesn't appear to have anything related to TwwQuery. No search results indicated compatibility or working mode between these two. These is another document explaining the work of Delphi, BDE Component and the Query function. Use the following website to read it: http://www.prestwood.com/aspsuite/kb/document_view.asp?qid=100296
InfoPower Studio is the most popular and useful component suite for building database front-ends for Delphi and C Builder. InfoPower Studio seamlessly integrates sorting, filtering, and grouping directly into the grid through drop-down menus in the grid titles. The end-user can also add and remove columns on the fly. Exporting to XML is also now supported. Gestures are also integrated into both InfoPower and 1stClass.
