I would like to implement a program which allow users to save files with a open file dialog. However, I can't find any file dialog API avaliabe in the SDK. would anyone tell me which class should I use ?
Unfortunately open file dialog is not part of the Series 60 design. Users are not meant to see the directory structure.
As a workaround, you can create a listbox. In the listbox you can list files that you would like your user to select from.
