Hi I am having an issue with the Task Scheduler API in my QT C++ program. I used the example code for a logon trigger here.

The first error I got was CoInitializeSecurity failed: RPC_E_TOO_LATE which means
CoInitializeSecurity has already been called. according to here. So I commented out the coinitializesecurity call and it fixed that.

However now I am getting the 80041318 error when trying to do the very last RegisterTaskDefinition step. I read here this means a value incorrectly formatted or out of range and also possibly an incorrect argument to pLogonTrigger. I tried commenting out the start boundary and end boundary code for the pLogonTrigger which didn't help. I also changed the changing the pLogonTrigger UserId and the userId parameter to the RegisterTaskDefinition function to my account as L"Josh". The only arguments to pLogonTrigger that are left are specified via put_Id and put_UserId.

Should I include any code if that would help and if so which code? The code is pretty much identical to the example code except for the pLogonTrigger modifications, the userId mods, and the commenting out of the cointializesecurity.

        case SCHED_S_SOME_TRIGGERS_FAILED:
            code = "SCHED_S_SOME_TRIGGERS_FAILED";
            break;

        return;
    }

    updateStatus(" Success! Task successfully registered. " );

    // Clean up
    pRootFolder->Release();
    pTask->Release();
    pRegisteredTask->Release();
    CoUninitialize();
}

Finally solved this problem after lots of troubleshooting... the answer is simple: set UserId to the appropriate user, in my case "Josh", you can use the Win32 API getusername function if you need to

hr = pLogonTrigger->put_UserId( _bstr_t( L"Josh" ) );

and then for RegisterTaskDefinition do this:

VARIANT varPassword;
varPassword.vt = VT_EMPTY;
hr = pRootFolder->RegisterTaskDefinition(
            _bstr_t( wszTaskName ),
            pTask,
            TASK_CREATE_OR_UPDATE,
            _variant_t(L"Builtin\\Administrators"),
            varPassword,
            TASK_LOGON_GROUP,
            _variant_t(L""),
            &pRegisteredTask);

So the userID parameter for RegisterTaskDefinition needs to be _variant_t(L"Builtin\Administrators") and the logonType needs to be TASK_LOGON_GROUP

So the main point is the two UserId values aren't necessarily the same.
