Scanning From .NET Scanner's GUI Opens And Then Closes

Mar 31, 2012

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?

I come straight to the point without going too far. I need to scan all the pixels of a generic image and for each pixel derive the RGB components. I started with the following function that performs its task very good and returns 3 array (R, G, B) with the different values, but unfortunately is too slow.

Image Scanner And Then Click

Dec 27, 2009

I am creating a program and one of its functions is that it will go to a website and click on an image. I would normally use the invoke command but since it is an image I need to click I need to go this way. I am not sure how I could go about doing this. I believe I would need to take a screenshot then scan for a bmp image I have saved of the button. Then some how send a mouse click to that image without moving the mouse. Here is what I have so far, all it is is a function to take a screenshot.

WIA Scanning With ADF Scanners?

Feb 15, 2012

I 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.

Psudo Code:
Start:
"Set scan settings"

Scanning From Twain Driver?

Jan 28, 2011

So - 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, 2010

I 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, 2012

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.

Scanning Remote Directory For Files?

Apr 19, 2011

I'm not really sure where to begin for this. I'd like to scan a specified server directory for all files that it contains in the directory. (I will then compare the sizes to files already existing on the user's machine, but that I've got covered.)

If there's any way I could get around using FTP, I'd be very grateful, as this won't be entirely secure.

I did some exploring of the WebClient and WebRequest classes, but failed to conceive of a way to do this.

C# - Does There Exist Any NON-GPL / AGPL Virus Scanning Library

Feb 18, 2011

Is 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).
