I am using the leadtools for .NET and i have an autofeeding scanner. I start a scan using the twainsession.acquire method and check the page in the AcquirePage event. Based on what I find out about that page, I want to be able to continue scanning the rest of the pages in the hopper or cancel the scan completely. I know how to continue, but how do I cause the current scan to cancel?

Thanks

TwainAcquirePageEventArgs now has a Cancel property. Set this during the AcquirePage event to cancel scanning.

Can someone please post a sample of VB.NET code for this? I cannot locate the Cancel property.

What is the exact
build number that you have (from the version info tab of the DLL file properties)?

In the main VB demo
located at the following path "LEAD Technologies, Inc\LEADTOOLS 14.5\Examples\Dotnet\v20\VB\MainDemo"
search for the function "_twainSession_AcquirePage" and set the property "e.Cancel() = True".
