MarshallSoft GPS Component for Visual Basic

The MarshallSoft GPS Component for Visual Basic (MGC4VB) is a Win32 DLL that allows any Visual Basic program to receive and decode standard NMEA 183 sentences from a GPS receiver connected to the RS232 serial port. Requires 32-bit Visual Basic or VB.Net.

MGC4VB includes the following:

• Uses the Windows Win32 API (Win64 API for 64-bit apps) for serial port input.
• Works with both real and virtual serial ports.
• Runs as a background thread unattended.
• The most current GPS data is always available on demand.
• Support functions (such as mgcGreatCircle) are included.
• Can be called from any application program capable of calling the Windows Win32 API, including C/C++, Visual Basic, PowerBASIC, Delphi, Visual FoxPro, Visual dBase, Xbase++, Fortran, COBOL, etc.
• Most commonly used NMEA sentence types are automatically decoded.
• MGC is a standard Windows DLL that does not depend on support DLLs.
• Several latitude/longitude calculation functions included.

Several example programs are provided, including examples for 32-bit Visual Basic and VB.Net.

MGC4VB can be used in the development of Win32 applications running under Windows 95/98/Me/NT/2000/XP/Vista/Win 7. The evaluation version of MGC4VB is fully functional. Registration is $115 for email delivery and includes one year free updates.

MGC4VB is also available with source code for $195.
