Please see this excellent introduction to EZTwain for Visual FoxPro developers by Mike Lewis of Mike Lewis Consultants Ltd . EZTwain Pro 3 includes a complete FoxPro header file (eztwain.prg) translated mechanically from the eztwain.h C/C++ header file. See the EZTwain Pro product page, or download the developer kit. The Code Wizard can walk you through the process of adding EZTwain support to your VFP code, including writing basic code for most common scenarios. Please contact Dosadi technical support if you encounter any problems using EZTwain Pro 3 from Visual FoxPro. We are committed to resolving such problems promptly and supported VFP developers.
