Bar Code Reading Stops | Developer Portal

Bar Code Reading Stops // Expert user has replied. V Vikrant Vaishampayan 3 years 6 months ago 1 4 0 Device Used MC3100 OS Windows CE 6.0 EMDK 2.6 I am developing an application for reading a 1D barcode. I am facing 2 issues. 1. The application was developed using the VB.Net sample for reading the Bar Code from EMDK 2.6. When the application is run the bar code is read successfully once. No further reads are possible. Pressing the trigger activates the laser but no barcode is read. Restarting the application does not help. A Warm Boot will allow the bar code to be read once more! This peculiar behaviour occurs with my application as well as the sample application from the EMDK. Could it be that subsequent reads are controlled by Data Wedge? I could not see Data Wedge installed on the device. 2. The data is to be saved into SQL Server 2008 R2 Express. I copied and ran the sql.wce5.armv4i.CAB on the device. The SQL connectivity was successfully established. However after a Warm Boot the CAB needs to be reinstalled. How can I make it permanent. My application was run by copying it to the device. I have not run a Setup and installed it. Help appreciated.

Hi Vikrant,

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?

Thanks

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)?

Hi Vikrant,

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.
