File Upload and Download

With ‘Hydra4GL’ 4.3, the developer can integrate facilities to upload and download data between client and server using the functions fgl_upload() and fgl_download().

The main benefit of having such functionality is that in a networked system, passing files between the application server and the client would usually require an intermediary technology that may present compatibility issues. With fgl_upload() and fgl_download() this is no longer an issue as there is a direct connection between the application and the client.

File Dialogbox

The new function fgl_dialog_box() enables the user to open or save a file in a graphical environment. This function uses the native file dialog box provided by the operating system. This makes it look and feel familiar for any user. Additionally, users are able to select specific file extensions for opening or saving and users can now select multiple files to open from within the same file dialog box.
