Hi ,
even i have the same issue.
can u please let me know how can i load and unload a driver from an
application.
Use the local Service Control Manager (SCM) API. Assuming you have
the driver installed on the system, you just have to:
- Connect to the local SCM, using OpenSCManager()
- Enable the driver, using:
2.1. OpenService()
2.2. StartService()
2.3. CloseServiceHandle()
- Use whatever code you need from your driver, by:
3.1. Opening the driver’s device, using CreateFile()
3.2. Communicating with the driver, using DeviceIoControl()
3.3. Closing the driver’s device, using CloseHandle()
- Disable the driver, using:
4.1. OpenService()
4.2. ControlService(…SERVICE_CONTROL_STOP…)
4.3. CloseServiceHandle()
- Disconnect from the local SCM, using CloseServiceHandle()
If you wish to install/remove the driver from the system, you must have
Administrator privileges. You may then use CreateService() and
DeleteService() - but if you’re developing a user mode application, the
above steps should be enough for your needs.
Hope it helps,
