Microsoft Pos .net 1.12
My scanner application keeps throwing an error 'Method open threw an exception. Could not read the device name key's default value or could not convert the Programmatic ID it holds int a valid class ID.' The application has worked successfully over a long period on Windows XP, but since moving to Windows 7, I keep seeing this error message.The error occurs at the MyScanner.Open command below. Following some investigation, I thought that my application was looking at the wrong version of the.NET Framework (.NET 3.5) for Windows 7, so I created a new version of the application that ispointing to.NET Framework 4 and installed this on my Windows 7 machine.
Apologies in advance - Iam 'relatively' new to the forum. I have trawled the net for advice, but come up with nothing that solves my problem.I have a Symbol LS2208 Barcode reader and want to use it in a simple vb.net application. I dont want to use it in keyboard mode as I dont want to have to manage the focus of a textbox.I am on windows 7 64 bit. I am using Visual Basic 2010. I have downloaded the MS POS of.net 1.12 and referenced the application to the MicrosoftPointOfService.dll. I haveImportsMicrosoft.PointOfService and system.collections. I have tried to download the OPOS from Symbol - was sure if I have the right one or it is in the right place.
Alot seem to be for32bit systems.Dim scannerList = explorer.GetDevices( DeviceType.Scanner)For Each itemAs DeviceInfo In scannerListTextBox1.Text = item.ServiceObjectNamegivesSTISCANNERSTIUSBSCANNER - so there seems to be some connection occuringCan anyone help me proceed?PS iam using the VB express editionIs there another barcode scanner that is easier/more directly compatible with POS 1.12? The Example Service Object that comes with POS for.NET should work with the scanner. There have been reported glitches on 64-bit operating systems. Ideally, you want a service object from the manufacturer. OPOS drivers will work too, but service objectis better. Symbol should have one.
Lets stick with the test application. The STIUSBSCANNER is working and that is a good sign. Where did STIUSBSCANNER come from? Did you install a SO driver from Motorola? If so, an XML point to the example scanner is not needed since the manufacturersSO is hardcoded - you have to read about service object in the book to understand how they did this.
Also, the example scanner that comes with the SDK is just that an example, and not good for production. It is best to use the SO that comes from the manufacturer.Remove the XML file and try the custom application.www.annabooks.com / www.seanliming.com / Book Author - Pro Guide to WE8S, Pro Guide to WES 7, Pro Guide to POS for.NET.
