Cannot Set Capabilities Of Scanner Through Twain Driver
Sep 9, 2011I have been working with TWAIN driver for few days. I have learnt how to connect to the scanner or get the working scanners connected to the machine. I am having a problem now, eventhough i get connected to the scanner, I am not able to set the capabilities from my application. The scanner scans using the capabilities that are set on it but not from my application. I have looked at the sample code given with twain pro but even that doesnt set the capabilities of the scanner. For example if the scanner is set to 300 dpi and I set 200dpi from my application, the scanner scans with 300 dpi. It gives me an error saying that the value given is out of range.

Scanning From Twain Driver?
Jan 28, 2011So - we are FED UP with our medical records packaging (document imaging) system and want to create a simple filing interface for our scanners to use in VB. Part of this deal is getting VB to interact with a TWAIN Driver.
There is some code out there for ASP.NET and C# - does anyone know of a VB.Net based code I could look at?
I have spent part of my day trying to recreate the ASP into VB but the calls are just different enough to get interesting.
Scanning With TWAIN - Hide The UI
Feb 18, 2010I am making an application to scan with TWAIN. I can get to state 4 OK, and scan with the UI. But I need to hide the UI. When I do this the scanner does nothing. I believe it needs some capabilities set (like height and width). So I try to get the physical height and width so I can set them. Herein lies the problem. I get 18874402 back for the physical height and width. (neither can I get the units). I get RC=SUCCESS. I don't think it could be a signed/unsigned issue because what boundary is at 18 million +/- with whatever units? I tried some other code I found but that returns 0. I can't figure out what I am doing wrong. Here's the code:

Perform Twain Scanning Using The Twain_32.dll?
May 2, 2012I am trying to perform Twain scanning using the twain_32.dll, but no luck. Whatever solutions I have got call the dll GUI.
I want to perform scanning by passing custom settings to the scanner for every scan. For eg. In duplex I want to scan the Front side in color & Back side in Grayscale. OR Scan every Alternate page as Color and B/W
The combination can be anything. I've tried & and succeeded using WIA but it limited me to a certain extent. how to proceed using TWAIN and without displaying the GUI. I am open to options where a communication to Twain Connection Manager is established & commands are passed.
Write A Program That Will Capture A Twain Scan?
May 17, 2011I need to write a program that will capture a twain scan, then let the user input a file name and append a date and time stamp to the file. Afterwards, it should upload the file to a ftp share on our network. As a bonus, I would like it to log the transaction to a SQL server so we can verify the file was uploaded. The catch is, I have almost no programming experience. I have written a small program here and there, but never something that I had to call an outside source for besides SQL. We do have an in-house VB programmer, but he is to busy to do something like this. I wanted to give it a try myself before hiring someone else to do it since it sounds like such a simple program. I know how to layout the basic forms and I can probably figure out how to log the transaction, but I am looking for examples on twain scans and saving to ftp.

Jul 21, 2010I am writing an inventory control application in which a barcode scanner will be hooked up to a laptop computer in our shipping/receiving department. What I'm wondering is, whenever a shipment comes in and the receiving clerk starts scanning the products, what exactly do I need to do in order to setup our database so that the scanner recognizes which vendor/product etc. and puts the data in the correct tables. I've written inventory control apps before but never one that incorporated the use of a barcode scanner.

C# - Distinguish Between The Scanner And The Keyboard
Apr 12, 2011I have a barcode scanner connected to a PC that working with a c# program.now i want to distinguish between the scanner and the keyboard which one is sending data to my program.
somebody said this to me in another topic(but i can't do this yet): basically you can configure the scanner to send some characters that basically tell the computer "hi, it's me". When you see those characters in your input stream, you know the information is coming from the barcode scanner, not from something the user typed on the keyboard. Did you check the manual that came with your barcode scanner? It should have more information about this.

Here is what I have so far, all it is is a function to take a screenshot.
