thats the error that i get on unloading a driver i made

"DRIVER_UNLOADED_WITHOUT_CANCELLING_PENDING_OPERATION"

Why this error popup on a cute blue screen only when unloading? this is my function of unload

usermode:

Quote:

void __fastcall TfrmMain::btnUnloadClick(TObject *Sender)
{
ControlService(hService, SERVICE_CONTROL_STOP, &ss);
CloseServiceHandle(hService);
DeleteService(hService);
CloseServiceHandle(hSCManager);
}

the unload function

Code:

void Unload(IN PDRIVER_OBJECT DriverObject)
{

UNICODE_STRING myDosDeviceName;

DisableInt();
// i restore some bytes here from a inline hook
EnableInt();

RtlInitUnicodeString(&myDosDeviceName, L"\\DosDevices\\Arepa");
IoDeleteSymbolicLink(&myDosDeviceName);

IoDeleteDevice(DriverObject->DeviceObject);
}
