Hi Farhad,

You're welcome.

>Dear Sergey,
>
>Thank you so much for your guide, as always your helps are useful, There is an activeX control in www.logix4u.net which its name is hwinterface.ocx with Inpout32.dll and they are working in VFP 8.0, inport and outport are methods in hwinterface activeX and we can use them easily in NT clone operating systems (WinNT/Win2K/WinXP).

>>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 ?
