CodeSnip Old Code (SVN)

Added new TCategoryInfo record that fully describes a category. Has Assign and Init methods.

* Renamed TUserDBMgr's Add, Edit and Delete methods to AddSnippet, EditSnippet and DeleteSnippet respectively to avoid confusion with similar methods that act on categories.
* Updated FmMain to use the renamed methods.

Changed TExceptionHandler.Handler to treat EFileStreamError exceptions as "expected" rather than "bug" exceptions. This fixes a bug in the database backup code (and other code the creates a file via a file stream) that was reporting a bug when a file was locked for writing.

Added paragraph that notes that users can defined their own categories.

Added brief note to "Customise Database" section that user defined categories can now be defined.

Added entries for Database menu's new Add Category, Rename Category and Delete Category menu options.

Added new help topics and index entries for new Add Category, Rename Category and Delete Category dialog boxes.

Fixed typo in select category prompt.

Marked TGenericDlg.CustomiseForm method as final.

Changed TMailingListDlg.ArrangeForm to use TCtrlArranger's new TotalControlHeight method instead of MaxContainerHeight.
