How stop Datawedge.exe or Scanwedge.exe programmatically?

i have to create program use RFID module and Scanwedge.exe in wm6.0 MC9090 serise.

but when trigger event fired, work RFID and Scanwedge same time.

so, i want to stop scanwedge(or datawedge) when use rfid module.

and i find one way do this - kill scanwedge process programmatically and after rfid work create scanwedge process.

but i think it's not good way.

i want to block trigger event for scanwedge.exe or just stop scanwedge during rfid works.

it is possible? how can I this?
