You can interface a PIC to the PC depending on exactly what you want or you can make it easy using a simple device like this one or maybe you could use this one. You don't mention the resolution you want in the A to D conversion process like 10 bit, 12 bit or more?

Additionally you don't mention what version of VB you plan to use but I guess it doesn't matter to much.

You may want to consider using the USB port for your comm port (interface) as the Parallel Port is just about dead and seldom seen on new systems, likewise the RS232 port is going away. More information would help and as to interfacing the PC to the PIC you may want to post in the Microcontrollers section of the forums.

hi,
As the notes say, you need to install the Visual Basic runtime files, free download from the web, install the runtime files into the Windows/System32 folder.
These run time files are often required for VB created programs.
I have included all the files in my DV4.zip folder, including DLL's needed to control the PC parallel port.
