I've installed visual studio 2008.is the visual basic in that package known as VB.net? My 2nd question: how can i use scanner for scanning using VB.net?do i have to use WIA? or i can use the default program for scanning?
View 1 RepliesI have been messing around with the scanning packages(WIA and TWAIN) and have gotten WIA to work, but not as intended. At first I used the common dialog to show a Image Aquisition Wizard, but that did not return desired results. Next was twain, but st managed to find was the same C# program over and over and over again, "TwainGUI". A program written by NETMaster on codeproject.What I would like to do is scan from the ADF and save immediately to the users working directory. The problem is I can't get WIA to keep scanning until the ADF is empty.

Start:
"Set scan settings"

View 4 RepliesSo - 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.

View 12 RepliesI 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:

So I got a request to update specific information on a thumb drive from my program. The idea is that the user does not have to select the drive.

I 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.
I developed a winform .NET 4 application that has the ability to asyncronous save image from scanner using Bytescout Scan. Anyway I noticed that in some cases (with some scanners) the scanner's GUI opens and then closes immediately after load without performing any scan. Since no error message is raised either from my code and from scanner software itself; is there some settings/tweak somewhere I should pay attention?

Alright well, I'm sort of new to VB.NET.I want to create a scanner that scans websites from lets say google or bing.It then dumps those websites into a list/textbox.

View 1 RepliesIs there any C#/.NET code (or anything that is easily convertible to .NET, such as Java/Python) for virus scanning that is not under the GPL/AGPL ? I found a C# wrapper for ClamAV, but ClamAV is GPL... Something LGPL would already suffice, and as a matter of fact, would be something I prefer. Preferably something in fully managed code, but DllImport is also welcome. COM interop is a no-go, I need it cross-platform (=Windows & Linux).
