Here is a sample of how we use the async methods to process a batch of devices. We initiate N find device requests, wait on the async handles, then query for each response.
for (int j = 0; j < asyncCnt; j++)
{
findDeviceForUser request = new findDeviceForUser();
request.loadDeviceServiceAttributes = true;
request.locale = _locale;
request.userId = userIds[i + j];
// make the async calls
findDeviceResponses[j] = _coreWebService.BeginfindDeviceForUser(request, null, null);
hFindDevices[j] = findDeviceResponses[j].AsyncWaitHandle;
}
if (System.Threading.WaitHandle.WaitAll(hFindDevices, nTimeout, false))
{
// write the data from async calls to respective output files
for (int j = 0; j < asyncCnt; j++)
{
try
{
FindDeviceForUserResult result =_coreWebService.EndfindDeviceForUser(findDeviceResponses[j]).returnValue;
...
The EndfindDeviceForUser only returns the error status for a single device, and the same device fails each time.
All properties for this device appear normal and up to date in the BAS view.
