Regarding Clipper and Page Scanners

[jeff66]

Looking to incorporate page scanner into my clipper application (version ver5.2E) or x-base. Trying to use a page scanner within my application to scan and assign file name that I will give it. Either program will do, but preferably the clipper program.

You could put the files in a special-setup dir (C:\scanned), and have the Clipper app scan with Directory() function to find all available files, and process the files not already processed, or move processed files to a .\Processd subdir (just 8 chars ;-) )

do you want your clipper app to run the scanner?

 

[jeff66]

yes !!!!

Switch to xHarbour (

and use the DLL or COM interface to connect to the TWAIN libraries delivered with the scanner.
There are numerous samples for other languages on the i-net, like Delphi/Pascal or C++, so you should be able to find a solution.

Clipper won't allow you to directly call DLL's or COM objects, except by using the Vouch32.lib (

search for Library or go to forum at

http://www.vouch.ws/Vouch32)

that uses external parts to achieve that, but remember that DOS apps do not perform very well on modern Windows versions like 2000 or XP.

I developed a clipper app some years ago that ran the twain compliant scanner to scan in resumes. Worked pretty slick, so it can be done...

 

[jeff66]

ok how did you do it.

I linked in a library that gives my Clipper code functions to run a scanner, like "scan" and "view" and "print."
works pretty slick and is seamless; no exiting Clipper app to run a scanner program, etc.
I had the lib developed for my own use and would consider selling you a copy. email me at circes9@excite.com if interested.
