FSX [Solved]TaggedData sample

Hi,

I'm trying to use this sample : http://msdn.microsoft.com/en-us/library/cc730357.aspx

The probematic part:

[...]
        case SIMCONNECT_RECV_ID_SIMOBJECT_DATA:
            ;
            {
                SIMCONNECT_RECV_SIMOBJECT_DATA *pObjData = (SIMCONNECT_RECV_SIMOBJECT_DATA*)pData;

                switch (pObjData->dwRequestID)
                {
                    case REQUEST_PDR:
                        ;
                        {
                            int    count = 0;;
                            StructDatum *pS = (StructDatum*)pObjData->dwData;

                            // There can be a minimum of 1 and a maximum of maxReturnedItems
                            // in the StructDatum structure. The actual number returned will
                            // be held in the dwDefineCount parameter.

                            while (count < (int)pObjData->dwDefineCount)
                            {
                                switch (pS->datum[count].id)
[...]

The sample stop at "switch (pS->datum[count].id)" with this error : "Violation d'accès lors de la lecture de l'emplacement 0x00000000."
That's because pObjData->dwData = 0 then pS too
But the sdk documentation say :

dwData
A data array containing information on a specified object in 8-byte (double word) elements. The length of the array is dwDefineCount.

and dwDefineCount = 2.
So, i don't know why the data received have this value.

Does someone sees a mistake in the sample ?

Thank you,
Will

My bad..
I found it.
In the sample :

StructDatum *pS = (StructDatum*)&pObjData;->dwData

I changed it on :

StructDatum *pS = (StructDatum*)pObjData->dwData

I thought that ";" and "&" were both bad character but ";" is the only one

dwData is a pointer itself so there shouldn't be a & there.
