Trying to turnoff barcode scanning when my program throws a modal.

Thanks for reading this post.  I have been using Symbol.barcode libary for a while.  Some of the MC67s that i have does turn off barcode scanning when my custom program gives users dialog window.  Our application runs on Windows mobile 6.X platform.


However, some of the same device does not turn off barcode scanning as our dialog is still waiting for user closing the dialog window.  So here I am trying to programmatically turn off the scanner and there seems to be no handle to do so in the Symbol.barcode library.  Please help.


I have also explored the use DataWedgeAPI.  However, Symbol.barcode reader seems to be ignoring the DataWedge's turn off signal and still allows users to scan data.  What to do??
