The JvTimeFrameDemo of the JVCL Lazarus port uses an SQLite3 database to store
the data. In order to run this demo you must have SQLite3 installed, or you must
copy the sqlite3.dll to the folder with JvTimeFrameDemo.exe.
It is also required to copy the data base file, data.sqlite, from the source
directory (the directory which contains this readme.txt) to the folder with
JvTimeFrameDemo.exe.
--------------------------------------------------------------------------------
Original text:
The PhotoOp demo uses a Paradox database to store the data. In order to run this
demo, you need to have the BDE installed and correctly configured. In addition,
the path to the data is restricted in Paradox. If you get an error about the
path being too long when you start the application, copy the executable and
the \Data subfolder from the source folder to a folder with a shorter path and
run the demo from that location instead.
