To use the driver with Visual Basic 4.0, 5.0 or 6.0 (for 32-bit applications), the user must include the GXPRES.BAS to the project. For Visual Basic .NET use the GXPRES.VB.
The file can be loaded using Add File from the Visual Basic File menu. The GXPRES.BAS/.VB contains function declarations for the DLL driver.
