Using DPFLOAT with Visual Basic

The VB subdirectory in the distribution contains a small example program in
Visual Basic that makes use of DPFLOAT. It compiles with Visual Basic 4.0,
32bit version. Please note the hardcoded path to the USERS file. You
may have to change that in the source code.

For 32bit include DPFLT32.BAS in your project. It contains the function
declarations for DPFLT32.DLL. Those take care of the "Stdcall Name Decoration"
in the 32bit DLL.
For 16bit include DPFLT.BAS in your project. It contains the function
declarations for DPFLT.DLL.
The enclosed USERS.BAS (structure of the USERS file) has the PowerBBS 8 byte
"double" values split into two "Single" values as explained in DPFLT.TXT.
In Visual Basic,
"Single"  denotes a 4 byte floating point value in IEEE format
"Long"    denotes a 4 byte long integer
"Integer" denotes a 2 byte integer
"Byte"    denotes 1 byte
