I have been trying to interface to the parallel port with visual basic express using a dll, I have tried two: inpout.dll and vbasm.dll. I make the program on windows vista and then I transfer it to windows XP with a flash drive. when I compile the program and transfer the program to XP I get an error message I think it has somthing to do with finding the dll, but I know I have placed the dll in the right file and used the right code.

Please help!

 

What is the error message?

Try registering the dll on the XP pc. Open a command prompt and type 'regsvr32 <enter dll path/name>'.
