Simply Powerful ToolKit in short SPTK is a powerful widget toolkit based on the Fast and Light ToolKit (FLTK).
The goal of this library is to create the easy-to-use, compact and effective library of controls to extend the abilities of FLTK library.
It is geared for business-style application development with database support (ODBC). All the widgets support database connectivity. A special CDialog class makes editing database records very easy. Every widget can be connected to the field, and CDialog can be connected to the database table.
Most of the controls are database-bound. If you place them on the CDialog-derived window they can load and save information from/to database.
This is the first release version of my controls(widgets) library that was designed to work with FLTK. Im using it for about a year in the production project.
Enhancements:
- Fixed a bug in CField::asString() that cause returning an empty string for some non-empty fields.
- Added couple of small fixes for better error hanling in CRegistry.

BADGER finance is an open source financial management application for end users. BADGER finance is written in php, ajax and sql. The goal is to regain control over your personal financial situation. BADGER is free software in the sense of the GNU GPL license.
The vision for BADGER finance was born at the Mannheim University of Cooperative Education (BA). In the course of a software development class we had the opportunity to develop software. We jumped at the project with the hopes to be able to complete a useful piece of software instead of the 10,000th tic-tac-toe application.
Since there was no financial management software on the market available to us that had what we needed, we started developing our own which we now released to the open source community.Preferences
