Zydacron Corporation- Manchester NH. needed Physical Device Drivers (PDD) designed and coded to complete a large commitment to Siemens Nixdorf for video conferencing systems for the OS/2 operating system. The pieces constructed involved building the Level 0 PDD as well as a Dynamic Link Library (DLL). The PDD was complicated; a large amount of control and data processing was needed. The DLL effected a complex Applications Program Interface (API) to allow easier ports of existing applications software |
Vivo Corporation- Waltham MA. needed a Graphical User Interface (GUI) constructed in an Operating System other than their standard one. I selected a new but very robust C++ library suitable to replicate the interface. A challenge was that the Library's infant, screen builder tool was in terrible shape. The solution was to hand roll the interface by writing the C++ code needed to incorporate the new graphical library. The product was produced on time to the delight of the client. |
