Scan

I am using VB6.0 SP5 on XP-Pro SP2

Question
Is there anyway once a document is scanned into my programs folder, that it
can be call from my application.

I would need to be able to call it up and draw on it, and enter notes on the
document.

I need to scan in floor layouts for different house types, and then make
notes on the areas that the Carpenter needs to fix.

Is this possible with VB???

Please clairify.

Do you want to:

1) Scan documents from within a VB6 program.

2) Edit images (scanned or not) with a VB6 program.

3) Both.

All can be done in VB6 fairly eaisily. A simple implementation
can be done with minimal code and in under an hour.

Scaning merely involes calling a twain driver (or whatever
it's called) - it does most of the work.

Editing an image (like adding markup or notes) can be done
with a picturebox - though I think it limited to what kind
of images it can load. I have seen intorduction to VB
turtorials that create a paint-like program.

After going throught the 500 page document on twain and implementing my own
twain code in C#, I can say with certainty that this is neither mere nor
will be done in one hour. Possibly your planning on using a third party
library but you did not state that.

I would advise doing this in dot net. The capabilities of dot net with
imaging are massively improved over vb6. VB6 only has a handful of imaging
functions where dot net has literally thousands. If you're looking for
someone to do the work I have a lot of the functionality already working in
C# that you would require (eg twain driver and WIA drivers).

Why all the twain business? Is it just me, or hasn't the OP stated that the
documents are already scanned, and stored in a folder (probably as TIFF files)?

I noticed that but thought I'd just jump immediately to the next step which
is to have the program scan the docs. Smile

Well, yes...I personally would not attempt to write a twain driver in VB6.

I currently have very functional scanning capability built into
my app using EZTwain, downloaded from www.dosadi.com.

....and I wondered why the OP even mentioned scanning, which is
why I asked for calirification.

The OP appears to have lost interest... Smile

It was a bit of a bugger. Instead of having different API calls for
different functions, like everyone else, they have a single entry point and
the first parameter determines what function you are calling. I've never
seen this used anywhere else.

I probably should have done something like that Smile
