i'm trying to "Scan for hardware changes" programatically and all I can find so far is: [URL]

there's this: [URL] but it doesn't tell you how to implement it

View 3 RepliesI am trying to scan images in VB.NET. I searched this site for almost an hour and found questions, but little in the way of answers, but some redirection which did not resolve the issue.
I downloaded the example here [URL] which has 7 projects doing a whole bunch of things. I do not have the scanner attached to my PC. Nor can I run any of these examples which do way more than I am trying to do. Then I went here [URL], found the VB version on planetsourcecode, but it will not run. I tried to duplicate what it does, but I couldn't get either of these line to be recognized:
Imports TwainGui.vb.TwainLib
Imports TwainGUI.vb.GdiPlusLib
I understand that the differences between .NET and VB are huge, but what I fail to understand is why no one has been able to post an example of how to scan? My company is not willing to purchase any 3rd party tools and my boss believes it can be done through the api, which some posts seem to imply but fail to show how.
is there a way to add a progressbar to the scan button?i watched tons of videos and i cant figure it out

I am working on a small music player software that runs from the thumbdrive and does not need to be installed. The problem is that when ever i scan the directory for files, it will not scan unless I am running it on a computer that has previously compiled the code. Regardless of whether visual studio is installed or not. Below is the rountine for the scan that is not working. It seems to stop at the 'ForEach ti in hi.getfiles'.

I need to setup an application to scan a barcode from a packing slip and the associated fulfillment items on a windows CE 5.0 device and update the inventory on the server. I'm using VB.NET. However, what is the best way to interact with the database? Integration Services, ADO.NET, RDA... etc... it's a bit overwhelming trying to figure out what I should use to interact with the database.
