AepCalc

During college I became addicted to my HP 42S RPN calculator. After a while, I was unable to use non-RPN calculators. The calculator that came with Windows in addition to not being RPN, was awful.

I had been struggling with developing in Windows using the Win16 spec for a few years. When Borland released Delphi, I was very excited about the product, but disappointed that it used Pascal instead of C++. Eventually, Borland released C++ Builder. After buying my copy I decided that an RPN calculator would be my first application.

One of the things that I hated about the Windows calculator was that it either required use of the mouse or else required one to remember lots of unlogical hot key combinations. So, in order to fix this, I arranged the buttons of the calculator in the same position as the keys of the right side of the keyboard. In this way, simply by looking at the screen, a person would know which keys went with which functions.

I also wanted the calculator to be always handy. So, I placed it on the system tray and gave it the option of being always on top. In this way it could be easily popped up at any time.

The application has been extremely useful for me personally. I actually thought the application would meet with some success. However, aside from one day when a government agency bought 21 copies, it did not.
