Hi,

When I use the Pocket PC 2003 emulator with my application that uses the Symbol.dll and Symbol.Barcode.dll (version 1.0.5000.7) the following line throws a NullReferenceException.

this.MyReader = new Symbol.Barcode.Reader();

The same line (and the application) works fine if I use the version 1.0.5000.3 of the Symbol.dll and Symbol.Barcode.dll.

Any ideas I am using VS2005 and CF 2.0

Thanks,

-Suri

1. is there still a parameter-less constructor in .7 is there a factory method for creating the object

2. you'll probably try asking this in a pocket pc newsgroup, or a symbol forum/support site.

Suri,

Why are you using such and old version of the Symbol SDK The version 1.4 SDK for .NET is out and works much better then the previous versions I've used. My dll version is 1.4.1.1.

It's a long time since I worked on that, but

1. As I can recall, in case of VS2005, the Symbol SDK installation package didn't work correctly, and some manual steps were required. Check the Symbol's web site for details.

2. If you are experiencing the problem on the emulator, test it on a Symbol device.

I think it is an issue with the fact that the emulator doesn't emulate the bar code reader. I just put that chunk in a piece of code like

try nullreferenceexception

[ My barcode stuff ]

catch

end try

Seems a little messy but it works.
