Mini Agenda

This is a mini application developed primarily to denote some wonderful features of HMG.

Mini Agenda uses:

– A text (csv)  file for data source and Grid as browse of this file

– DEFINE ACTIVEX for “About” page from a .html file

– HFCL library ( Thanks to S. Rathinagiri for GridPrint )

Features :

– File operations: New, Open, ReOpen, Close, Save, Save as, Print

– Record operations:  Append, Delete, Insert

– Three way ( Natural, Ascending, Descending) sorting columns

– Preserve current item after sort

– In_place editing

– Incremental (and “soft” ) Search

– .ini File for keeping record of last used data file
