Give a bit more info...
What do u mean by 'communicating with scanner'

What are you trying to do?? exactly??

[davidrobin]

I am attempting to write a data bound ActiveX control which when the user presses the button will activate the scanner, scan in a document and save the image to an SQL database. The part I am trying to find out how to do is the scanning side without using the wang ImgScan controls.
1. Test a scanner is attached to PC
2. Operate a scanner
3. Accept the image
etc.
Also consideration into a scanner attached to a network.
I am on WindowsNT, VB6.

Most scanners are TWAIN. I'd be inclined to find a TWAIN ocx or dll and incorporate that into your project. Let the TWAIN driver do all the work- not much point writing that from scratch IMO, unless, of course, the objective of the project is to do it from first principles. Or your scanner isn't TWAIN!

Go and have a root around at http://www.twain.org . They have a resources page.

Or do a Google search. (Hint: do it -mark -shania or you'll get a gazillion of extra hits with nothing to do with scanning!). I used to have some TWAIN stuff I downloaded but can't find it. It might be on my PC at home, but I'm at work right now. I'll look this evening.

look for this handy tool, if acquiring images are all that you do, its name is 'eztwain'.
it use a eztw32.dll. provides two simple functions, 1. select source 2. acquire images. it calls your scanner driver and works well.
it should solve your problem :)

But i have mine unsolved ==>

i need to control the scanner to do batch scanning ( the scanner has this function.)

does anyone has any ocx or any examples of using TWAIN API ?

my project is running out of time. a thousand thx if anyone would help!
