I've make my Gauge.dll working with SimConnect. The first Thing i made was receiving the "SITUATION_SAVED" Event so i'm able to write my Configfile for the Panelstats if Users save a Flight. Now i want to tkae "Control over the Joystickinputs. Can read (intercept?) the Inputs with SimConnect succesfully but FSX is still responsing to the Inputs (what he should'nt do in the Moment). Have read about this "maskable" InputGroups but nothing helps. So, I post some Code here how it works at the Moment.GAUGE_CALLBACK sys_gauge_cb;HANDLE hSimConnect = NULL;static enum GROUP_ID { GROUP0,};static enum EVENT_ID { EVENT_FLIGHT_SAVE, EVENT_XAXIS,};static enum INPUT_ID { INPUT_XAXIS,};static enum DATA_DEFINE_ID { FLIGHTCONTROLS,};case PANEL_SERVICE_PRE_INSTALL:{{HRESULT hr;if (SUCCEEDED(SimConnect_Open(&hSimConnect, "Gauge", NULL, 0, 0, 0))){hr = SimConnect_MapClientEventToSimEvent(hSimConnect, EVENT_FLIGHT_SAVE, "SITUATION_SAVE");hr = SimConnect_MapClientEventToSimEvent(hSimConnect, EVENT_XAXIS);hr = SimConnect_AddClientEventToNotificationGroup(hSimConnect, GROUP0, EVENT_FLIGHT_SAVE);hr = SimConnect_AddClientEventToNotificationGroup(hSimConnect, GROUP0, EVENT_XAXIS, TRUE);hr = SimConnect_SetNotificationGroupPriority(hSimConnect, GROUP0, SIMCONNECT_GROUP_PRIORITY_DEFAULT); hr = SimConnect_MapInputEventToClientEvent(hSimConnect, INPUT_XAXIS, "joystick:0:XAxis", EVENT_XAXIS);hr = SimConnect_SetInputGroupPriority(hSimConnect, INPUT_XAXIS, SIMCONNECT_GROUP_PRIORITY_HIGHEST_MASKABLE);hr = SimConnect_SetInputGroupState(hSimConnect, INPUT_XAXIS, SIMCONNECT_STATE_ON);hr = SimConnect_AddToDataDefinition(hSimConnect, FLIGHTCONTROLS, "AILERON POSITION", NULL, SIMCONNECT_DATATYPE_INT32); hr = SimConnect_CallDispatch(hSimConnect, MyDispatchProc, NULL);}else{MessageBox(NULL, L"Failed connecting Flight Simulator", L"SimConnect Error", MB_OK | MB_ICONERROR);exit (-1);}}Thanks for any Help.Regards,Sven

I have been able to do what you're looking for. I think what you need to do is to set the event as maskable in MapInputEventToClientEvent(). Try using something along the lines of:hr = SimConnect_MapInputEventToClientEvent(hSimConnect, INPUT_XAXIS, "joystick:0:XAxis", EVENT_XAXIS, 0, (SIMCONNECT_CLIENT_EVENT_ID)SIMCONNECT_UNUSED, 0, true);I hope that will help you.Klas

Thanks for your help, works fine now :-)Regards,Sven
