Could you let us know what BSP you are running on the device? Also any indications on CPU/memory usage when the app is run?
How do I read the BSP details on the device?
How do I read the CPU & Memory Usage on the device?
Stangely after one more warm boot, the application (without any code changes) works fine without any hitch ! ! !
Could you help on Issue No. 2 (permanently installing the SQL drivers)?
On Issue No. 2, I can probably help.. but first let me make sure I understand the problem..
How are you initiating a warm boot?
Second, when you say "the cab needs to be re-installed" do you mean the files and registry settings that it created are gone?
I might expect this to happen on a cold boot, but not a warm boot.
I initiate the boot by pressing the keys 1 + 9 + Power.
This brings up the screen where the touch screen is reinitialized by clicking the cross in different locations.
The folder on the Handheld (where my application was copied to) is gone.
I copy my application once again and running it throws an SQL Exception as the SQL Driver CAB installation is gone.
I might be wrong in using the terms warm / cold. Do correct me.
All in all
1. how do I retain the SQL Driver installation?
2. do I need to run a SETUP file for my application?

1+9+power will perform a coldboot. All you should need to do is hold down the power button for 5 seconds to perform a warmboot. If you need to have the sql installation to occur after a coldboot, you can place the cab file in the \application\startup folder and it will be run after a coldboot. With that said, I'm not sure if it may actually be run after a warmboot as well. If you need better control of the startup process, I suggest you take a look at the StartupCtl product which can be downloaded from this link:
As far as the scanning issue; if you've verified that Datawedge is not running on the device, can you provide a code snippet of your application? You should also build one of our sample scanning apps and run it on the device to ensure that there's not a hardware problem.
i am not a vb.net guy, but c# . if you need some sample codes on how to do bar code reading. i can provide you some help. but first you have to make sure the hardware haven't go wrong.it is the snippets you are using should be changed.
