Check Inpout32.dll from http://www.logix4u.net/inpout32.htm

>I need to have access to parallel port, In Visual C++, We can do it by calling "inport" and "outport" functions and one way for making access to VFP is making an external library (.fll) by C for calling from VFP. Is there any other way for accessing the ports (Like parallel port) in VFP ?
