I am maintaing an application on a Symbol MC75 scan gun running WM 6.0. A request has been made to turn the Wi-Fi on, via the registry entry. It can happen 'behind the scenes' or I can have a button on the screen to invoke it, there is no restriction there.

I have narrowed the registry entry down to HKEY_LOCAL_MACHINE\System\State\Hardware\Wifi and created a registry file to change it.

Does anyone know if there is a way to have a .reg file run upon warm boot of the gun? I thought that I read that placing it in the Application directory would work (it doesn't) and now I can't locate where I read that to begin with. I know this is possible upon a cold boot.

Having had no success there, I attempted to execute it using regmerge, but it did not work either:

ProcessStartInfo psi = new ProcessStartInfo();
psi.FileName = "regmerge";
psi.Arguments = string.Format(@"-q \Application\WiFiBackOn.reg");

Process p = Process.Start(psi);

Does anyone have any suggestions on resolving this? Any input is greatly appreciated.

You can use the RegistryKey[^] class in the .Net CF to edit a registry value through code. So in your case, you could have a button that edits the registry key and then does a reboot.
