VS 2008 FilesystemWatcher - Treeview.invoke - Error "invoke Or Begininvoke Cannot Be Called On A Control Until The Window Handle Has Been Created"
Aug 27, 2010I have a filesystewatcher object. On it`s event it runs a procedure which fills a treeview with a data.

View 1 RepliesInvoke UI From Separate Thread Does Not Invoke
Oct 13, 2010We have a UI with a progressbar. I know how to invoke, safely, the control from which it was not created from a thread. there are threads being processed in a threadpool, all of which calls an "agent" (which is a notifier to raise an event back to the UI to then increase the progressbar). an "agent" is set as a property in a State object, which is then passed into a method which will be executed on the ThreadPool. so, I invoke on the UI the method to update the progressbar, but the bar does not seem to update at all (screen frozen) and it takes a very very long time for it to execute. without threading, no problem.

View 1 RepliesWIA Scanning With ADF Scanners?
Feb 15, 2012I 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.

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.

View 12 RepliesScanning 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.
Scanning From .NET Scanner's GUI Opens And Then Closes
Mar 31, 2012I 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?
