I'm trying to know when a certain file is sent to the drive trash. I've tried the following but nothing seems to work:
#POST
#Path("/webhook")
public void webhook(#Context HttpServletRequest request, #Context HttpServletResponse response) throws IOException {
Credential credential = initFlow().loadCredential("user");
Drive service = new Drive.Builder(HTTP_TRANSPORT, JSON_FACTORY, credential).setApplicationName(APPLICATION_NAME).build();
String pageToken = GDrive.savedPageToken;
Logger log = Logger.getLogger("thread");
log.setLevel(Level.INFO);
while (pageToken != null) {
ChangeList changes = service.changes().list(pageToken).execute();
for (Change change : changes.getChanges()) {
if ( change.getFile() == null ) {
log.info("IGNORE: "+change.getFileId());
}
else if (!change.getFile().getMimeType().equalsIgnoreCase("application/vnd.google-apps.folder")) {
log.info("TRASHED REMOVE DIGITAL INPUT: "+change.getFile().getTrashed());
log.info("TRASHED REMOVE DIGITAL INPUT: "+change.getRemoved());
log.info("TRASHED REMOVE DIGITAL INPUT: "+change.getFile().getExplicitlyTrashed());
log.info("TRASHED REMOVE DIGITAL INPUT: "+change.getFile().getName());
}
}
if (changes.getNewStartPageToken() != null) {
GDrive.savedPageToken = changes.getNewStartPageToken();
}
pageToken = changes.getNextPageToken();
}
response.setStatus(200);
}
The first condicion change.getFile() == null is for when file is completely removed from drive.
On the second one I try to see when a file is send to trash, but these functions getTrashed(), getRemoved(), getExplicityTrashed() are always null or false.
How I could know when a file is removed?

I am using aws_ai plugin and the response is in the form of
instance of Future<String>
I read the response as given below. I need to access specific value from json with key "confidence", how do I access it?
Future main1() async {
File sourceImagefile; //load source image in this File object
String accessKey = "",
secretKey = "",
region = "" ;
RekognitionHandler rekognition = new RekognitionHandler(accessKey, secretKey, region);
if(sourceImagefile !=null && targetImagefile !=null) {
Future<String> labelsArray = rekognition.compareFaces(
sourceImagefile, targetImagefile);
print(labelsArray);
return labelsArray.toString();
}else{
return "Enter Image";}
}
___________________________________
(later in widget build:)
___________________________________
onpressed(){
main1().then((labelsArray){
print("json value is: "+labelsArray);
});
}
the current result is :
json value is: Instance of 'Future<String>'
thanks for the help!
The reason you are getting the Instance of 'Future<String>' as a result is you are not waiting for the future to return and just getting the Future<String> object back refer this for more details:
The below code should solve your problem:
Future<String> futureFunction() async {
RekognitionHandler rekognition = new RekognitionHandler(accessKey, secretKey, region);
if(sourceImagefile !=null && targetImagefile !=null) {
var labelsArray = await rekognition.compareFaces(
sourceImagefile, targetImagefile);
print(labelsArray);
return labelsArray.toString();
} else {
return "enter image";
}
}
I'm in the process of learning the Forge platform. I'm currently using an example (Jigsawify) written by Kean Walmsley because it most accurately describes my goals. I'm running into an issue of getting my file to download from an Azure Storage Account to Forge. The error I receive is "The value for one of the HTTP headers is not in the correct format." My question is how does someone go about troubleshooting HTTP protocol when writing, in this case, a workitem in code? I can put in a breakpoint to view the workitem, but I'm not versed enough to understand where the flaw is in the HTTP header, or even where to find it. Is there a specific property of the workitem I should be looking at? If I could find the HTTP statement, I could test it, but I don't where I should find it.
Or am I just completely off base?
Anyway here's the code. It's a modified version of what Kean wrote:
static void SubmitWorkItem(Activity activity)
{
Console.WriteLine("Submitting workitem...");
CloudStorageAccount storageAccount =
CloudStorageAccount.Parse(Microsoft.Azure.CloudConfigurationManager.GetSetting("StorageConnectionString"));
StorageCredentials crd = storageAccount.Credentials;
CloudFileClient fileClient = storageAccount.CreateCloudFileClient();
CloudFileShare ShareRef = fileClient.GetShareReference("000scrub");
CloudFileDirectory rootDir = ShareRef.GetRootDirectoryReference();
CloudFile Fileshare = rootDir.GetFileReference("3359fort.dwg");
// Create a workitem
var wi = new WorkItem()
{
Id = "", // Must be set to empty
Arguments = new Arguments(),
ActivityId = activity.Id
};
if (Fileshare.Exists())
{
wi.Arguments.InputArguments.Add(new Argument()
{
Name = "HostDwg", // Must match the input parameter in activity
Resource = Fileshare.Uri.ToString(),
StorageProvider = StorageProvider.Generic // Generic HTTP download (vs A360)
});
}
wi.Arguments.OutputArguments.Add(new Argument()
{
Name = "Results", // Must match the output parameter in activity
StorageProvider = StorageProvider.Generic, // Generic HTTP upload (vs A360)
HttpVerb = HttpVerbType.POST, // Use HTTP POST when delivering result
Resource = null, // Use storage provided by AutoCAD.IO
ResourceKind = ResourceKind.ZipPackage // Upload as zip to output dir
});
container.AddToWorkItems(wi);
container.SaveChanges();
// Polling loop
do
{
Console.WriteLine("Sleeping for 2 sec...");
System.Threading.Thread.Sleep(2000);
container.LoadProperty(wi, "Status"); // HTTP request is made here
Console.WriteLine("WorkItem status: {0}", wi.Status);
}
while (
wi.Status == ExecutionStatus.Pending ||
wi.Status == ExecutionStatus.InProgress
);
// Re-query the service so that we can look at the details provided
// by the service
container.MergeOption =
Microsoft.OData.Client.MergeOption.OverwriteChanges;
wi = container.WorkItems.ByKey(wi.Id).GetValue();
// Resource property of the output argument "Results" will have
// the output url
var url =
wi.Arguments.OutputArguments.First(
a => a.Name == "Results"
).Resource;
if (url != null)
DownloadToDocs(url, "SGA.zip");
// Download the status report
url = wi.StatusDetails.Report;
if (url != null)
DownloadToDocs(url, "SGA-Report.txt");
}
Any help is appreciated,

Azure requires that you specify the x-ms-blob-type header when you upload to a presigned URL. See https://github.com/Autodesk-Forge/design.automation-.net-input.output.sample/blob/master/Program.cs#L167
So, I was able to figure out how to download my file from Azure to Forge using Albert's suggestion of moving to a blob service. Here's the code:
static void SubmitWorkItem(Activity activity)
{
Console.WriteLine("Submitting workitem...");
CloudStorageAccount storageAccount =
CloudStorageAccount.Parse(Microsoft.Azure.CloudConfigurationManager.GetSetting("StorageConnectionString"));
CloudBlobClient BlobClient = storageAccount.CreateCloudBlobClient();
CloudBlobContainer cloudBlobContainer = BlobClient.GetContainerReference("000scrub");
CloudBlockBlob blockBlob = cloudBlobContainer.GetBlockBlobReference("3359fort.dwg");
// Create a workitem
var wi = new WorkItem()
{
Id = "", // Must be set to empty
Arguments = new Arguments(),
ActivityId = activity.Id
};
if (blockBlob.Exists())
{
wi.Arguments.InputArguments.Add(new Argument()
{
Name = "HostDwg", // Must match the input parameter in activity
Resource = blockBlob.Uri.ToString(),
StorageProvider = StorageProvider.Generic, // Generic HTTP download (vs A360)
Headers = new System.Collections.ObjectModel.ObservableCollection<Header>()
{
new Header() { Name = "x-ms-blob-type", Value = "BlockBlob" } // This is required for Azure.
}
});
}
wi.Arguments.OutputArguments.Add(new Argument()
{
Name = "Results", // Must match the output parameter in activity
StorageProvider = StorageProvider.Generic, // Generic HTTP upload (vs A360)
HttpVerb = HttpVerbType.POST, // Use HTTP POST when delivering result
Resource = null, // Use storage provided by AutoCAD.IO
ResourceKind = ResourceKind.ZipPackage, // Upload as zip to output dir
});
container.AddToWorkItems(wi);
container.SaveChanges();
// Polling loop
do
{
Console.WriteLine("Sleeping for 2 sec...");
System.Threading.Thread.Sleep(2000);
container.LoadProperty(wi, "Status"); // HTTP request is made here
Console.WriteLine("WorkItem status: {0}", wi.Status);
}
while (
wi.Status == ExecutionStatus.Pending ||
wi.Status == ExecutionStatus.InProgress
);
// Re-query the service so that we can look at the details provided
// by the service
container.MergeOption =
Microsoft.OData.Client.MergeOption.OverwriteChanges;
wi = container.WorkItems.ByKey(wi.Id).GetValue();
// Resource property of the output argument "Results" will have
// the output url
var url =
wi.Arguments.OutputArguments.First(
a => a.Name == "Results"
).Resource;
if (url != null)
DownloadToDocs(url, "SGA.zip");
// Download the status report
url = wi.StatusDetails.Report;
if (url != null)
DownloadToDocs(url, "SGA-Report.txt");
}
What isn't complete is the result section. The ZIP has nothing in it, but hey, baby steps right?
Thanks Albert.

I am having trouble trying to retrieve large datasets from Azure TableStorage. After several attempts at trying to get it in one go I have given up and am now using the TableContinuation Token, which is now not getting Deserialized correctly.The object is getting created but all the Next... values (i.e. NextRowKey, NextPartitionKey, etc are NULL, when the in stringresponse that gets created you can see the values it should be populating with...
The class I am passing contains a list of objects and the token
public class FlorDataset
{
public List<FlorData> Flors { get; set; }
public TableContinuationToken Token { get; set; }
}
The controller code is not exactly rocket science either....
[HttpGet, Route("api/list/{token}")]
public IHttpActionResult FindAll(string token)
{
try
{
TableContinuationToken actualToken = token == "None"
? null
: new TableContinuationToken()
{
NextPartitionKey = NextPartition,
NextRowKey = token,
NextTableName = NextTableName
};
var x = Run(actualToken);
Flors = x.Flors;
actualToken = x.Token;
NextTableName = actualToken.NextTableName;
NextPartition = actualToken.NextPartitionKey;
return Flors != null
? (IHttpActionResult)new IsoncOkResult<FlorDataset>(x, this)
: NotFound();
}
catch (Exception ex)
{
Trace.TraceError(ex.ToString());
return NotFound();
}
}
private FlorDataset Run(TableContinuationToken token)
{
return _repo.GetAllByYear("2016", token) as FlorDataset;
}
The calling code, which calls my fairly standard Web API 2 Controller is:
do
{
try
{
HttpResponseMessage response = null;
if (string.IsNullOrEmpty(token.NextRowKey))
{
response = await client.GetAsync("api/list/None");
}
else
{
response = await client.GetAsync($"api/list/{token.NextRowKey}");
}
if (response.IsSuccessStatusCode)
{
var stringresponse = await response.Content.ReadAsStringAsync();
var ds = JsonConvert.DeserializeObject<FlorDataset>(stringresponse);
token = ds.Token;
Flors.AddRange(ds.Flors);
}
else
{
token = null;
}
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
token = null;
}
} while (token != null);
Okay, this is not the greatest solution, but it's the only thing that works so far in case anyone else is trying the same and stumbling across my question....
In the calling code bit you do a horrible bit of string replacement before you do the deserialisation.... I actually feel dirty just posting this, so if anyone comes up with a better answer, please feel free to share.....
if (response.IsSuccessStatusCode)
{
var stringresponse = await response.Content.ReadAsStringAsync();
stringresponse = stringresponse.Replace(">k__BackingField", "");
stringresponse = stringresponse.Replace("<", "");
var ds = JsonConvert.DeserializeObject<FlorDataset>(stringresponse);
token = ds.Token;
Flors.AddRange(ds.Flors);
}
Not nice, not pretty, but does work!!!! :-D Going to wash my fingers with bleach now!!!
I am uploading documents to Google Drive successfully but my meta-data does not appear to be getting back to me correctly.
protected File insertFile(Drive service, List<String> parentIds, com.google.drive.FileContent fileContent, File googleFile)throws IOException {
// Set the parent folder.
if (parentIds != null && parentIds.size() > 0) {
List<ParentReference> parentReferences = new ArrayList<ParentReference>();
for (String parentId : parentIds ){
parentReferences.add(new ParentReference().setId(parentId));
}
googleFile.setParents( parentReferences );
}
try {
googleFile = service.files().insert(googleFile, fileContent).execute();
// Uncomment the following line to print the File ID.
System.out.println("File ID: " + googleFile.getId());
return googleFile;
}
catch (IOException e) {
System.out.println("An error occured: " + e);
return null;
}
}
Above is my insert statement, below is what I am sending as details about the document.
{description=XXXXXXX Invoice, fileExtension=pdf,
indexableText={text=XXXXXXX Invoice}, labels={restricted=false},
mimeType=application/pdf, parents=[{id=0B_owsnWRsIy7S1VsWG1vNTYzM1k}],
properties=[{key=DocumentType, value=11}], title=XXXXXXX Invoice}
When I do a get for that same document using this code
protected InputStream downloadFile(Drive service, File file)throws IOException {
if (file.getDownloadUrl() != null && file.getDownloadUrl().length() > 0) {
HttpResponse resp =
service.getRequestFactory().buildGetRequest(new GenericUrl(file.getDownloadUrl()))
.execute();
return resp.getContent();
}
else {
// The file doesn't have any content stored on Drive.
return null;
}
}
I get most of the text back minus the indexable Text and File Extension, is that correct (Do not want to show since it contains a lot of information that is noise)?
Two separate issues here.
1) fileExtension is a read-only field so it is being ignored. When retrieving the information, it is derived from the original title/filename. Since your title doesn't include ".pdf" it is being set to empty.
2) indexableText is write-only in we don't allow you to retrieve it once set; it is only used by the drive backend to service search queries.
You can read more on the different metadata properties of the file resource in our documentation.
I tried posting this on the Exchange Development forum and didnt get any replies, so I will try here. Link to forum
I have a windows services that fires every fifteen minutes to see if there is any subscriptions that need to be created or updated. I am using the Managed API v1.1 against Exchange 2007 SP1. I have a table that stores all the users that want there mailbox monitored. So that when a notifcation comes in to the "Listening Service" I am able to look up the user and access the message to log it into the application we are building. In the table I have the following columns that store the subscription information:
SubscriptionId - VARCHAR(MAX)
Watermark - VARCHAR(MAX)
LastStatusUpdate - DATETIME
My services calls a function that queries the data needed (based on which function it is doing). If the user doesn't have a subscription already the service will go and create one. I am using impersonation to access the mailboxes. Here is my "ActiveSubscription" method that is fired when a user needs the subscription either created or updated.
private void ActivateSubscription(User user)
{
if (user.ADGUID.HasValue)
{
PrincipalContext ctx = new PrincipalContext(ContextType.Domain, Settings.ActiveDirectoryServerName, Settings.ActiveDirectoryRootContainer);
using (UserPrincipal up = UserPrincipal.FindByIdentity(ctx, IdentityType.Guid, user.ADGUID.Value.ToString()))
{
ewService.ImpersonatedUserId = new ImpersonatedUserId(ConnectingIdType.SID, up.Sid.Value);
}
}
else
{
ewService.ImpersonatedUserId = new ImpersonatedUserId(ConnectingIdType.SmtpAddress, user.EmailAddress);
}
PushSubscription pushSubscription = ewService.SubscribeToPushNotifications(
new FolderId[] { WellKnownFolderName.Inbox, WellKnownFolderName.SentItems },
Settings.ListenerService, 30, user.Watermark,
EventType.NewMail, EventType.Created);
user.Watermark = pushSubscription.Watermark;
user.SubscriptionID = pushSubscription.Id;
user.SubscriptionStatusDateTime = DateTime.Now.ToLocalTime();
_users.Update(user);
}
We have also ran the following cmdlet to give the user we are accessing the EWS with the ability to impersonate on the Exchange Server.
Get-ExchangeServer | where {$_.IsClientAccessServer -eq $TRUE} | ForEach-Object {Add-ADPermission -Identity $_.distinguishedname -User (Get-User -Identity mailmonitor | select-object).identity -extendedRight ms-Exch-EPI-Impersonation}
The "ActivateSubscription" code above works as expected. Or so I thought. When I was testing it I had it monitoring my mailbox and it worked great. The only problem I had to work around was that the subscription was firing twice when the item was a new mail in the inbox, I got a notification for the NewMail event and Created event. I implemented a work around that checks to make sure the message hasn't already been logged on my Listening service. It all worked great.
Today, we started testing two mailboxes being monitor at the same time. The two mailboxes were mine and another developers mailbox. We found the strangest behavior. My subscription worked as expected. But his didn't, the incoming part of his subscription work properly but any email he sent out the listening service never was sent a notification. Looking at the mailbox properties on Exchange I don't see any difference between his mailbox and mine. We even compared options/settings in Outlook. I can see no reasons why it works on my mailbox and not on his.
Is there something that I am missing when creating the subscription. I didn't think there was since my subscription works as expected.
My listening service code works perfectly well. I have placed the code below incase someone wants to see it to make sure it is not the issue.
Thanks in advance, Terry

I have two answers for you.
At first you will have to create one instance of ExchangeService per user. Like I understand your Code you just create one instance and switch the impersonation, which is not supported. I developed a windowsservice which is pretty similar to yours. Mine is synchronising the mails between our CRM and Exchange. So at startup I create an instance per user and Cache it as long as the application runs.
Now about cache-mode. The diffrence between using cache-mode and not is just a timing gab. In cache-mode Outlook synchronizes from time to time. And non cached it's in time. When you use the cache-mode and want the Events immediatly on your Exchange-Server you can press the "send and receive"-button in Outlook to force the sync.
Hope that helps you...
