NTDEV

Hello,

I’m searching for information regarding unload/reload drivers from a win32
program. Something’s similar to “Device Manager”.
Thank you for your help.

Hello.

Use:

CreateService\OpenService

StartService //Load and start
ControlService(,SERVICE_CONTROL_STOP,); //Unload
CloseServiceHandle

Regards,
Yan Vugenfirer.

Thanks again. But it only works on non-pnp driver. I got this error when
trying to stop my pnp driver:
“The requested control is not valid for this service.”
Am I missing something?

You will need to disable every device on which your driver is loaded.
This will result in the unload of your driver.

You should read up on the SetupDi API in the DDK documentation. This
API will let you enumerate devices and control their state.
