New Post: Cant obtain Access Token. Unauthorized exception.

hitme — Tue, 07 May 2013 21:14:05 GMT

It seems that Dropbox wont let me obtain access token. Any suggestions?
Steps 0-3 work fine but it stops on step 4 and gives and 'unauthorized exception' warning. I have entered the correct
consumer key and secret and it seems to accept those fine and wants to connect the users account to the application.
However it hangs on step 4.

    ' enter the consumer key and secret
    Dim ConsumerKey As String = "MyKey"

    Dim requestToken As DropBoxRequestToken

    Private Sub RequestButton1_Click(sender As System.Object, e As System.EventArgs) Handles RequestButton1.Click

        ' 0. set your own callback which will be called from DropBox after successful authorization
        config.AuthorizationCallBack = New Uri("http://www.google.com")

        ' 1. create a request token
        requestToken = DropBoxStorageProviderTools.GetDropBoxRequestToken(config, ConsumerKey, ConsumerSecret)

        ' 2. build the authorization url based on request
        Dim AuthorizationUrl As String = DropBoxStorageProviderTools.GetDropBoxAuthorizationUrl(config, requestToken)

        ' 3. Redirect the user to the website of dropbox
        Process.Start(AuthorizationUrl)

        ' 4. Exchange the request token into access token
        __Dim accessToken As ICloudStorageAccessToken = DropBoxStorageProviderTools.ExchangeDropBoxRequestTokenIntoAccessToken(config, ConsumerKey, ConsumerSecret, requestToken)__

        ' 5. Open the storage with the generated access token 
        Dim DropboxStorage As New CloudStorage()
        DropboxStorage.Open(config, accessToken)

        ' 6. write token for later use
        Dim tokenstream = DropboxStorage.SerializeSecurityToken(accessToken)
        Dim tokenfile As New FileStream("c:\MyToken.txt", FileMode.Create)

New Post: Status SharpBox Object-Store API

LievenJanssen — Mon, 06 May 2013 14:15:42 GMT

What is the status of the SharpBox Object-Store API?

We are currently using SharpBox to connect to Dropbox and WebDav but we need to be able to add metadata via WebDav. I would rather use or extend the SharpBox API to do this so I was wondering if SharpBox will still be actively developed and if the SharpBox Object-Store API is still in scope.

Commented Issue: DropboxTokenIssuer.exe not working [18848]

kooplar — Thu, 02 May 2013 04:53:02 GMT

The program used to generate the token files has stopped working for some reason. I was able to generate the files successfully about a month back, and now im trying the same process and it is not working, When I click Authorize, it displays the login page, I login and press Allow, and it gives me HTTP500 error. It would be nice to have a workaround for this problem.
Thanks.

New Post: Couldn't retrieve child elements from the server - Dropbox error

pdm2012 — Mon, 15 Apr 2013 18:47:39 GMT

Hello all,

I'm using GetFolder and DownloadFile to retrieve the contents of a folder in a Dropbox "Apps" directory. Occasionally, I'll get the following error:

"Couldn't retrieve child elements from the server"

However it's difficult to consistently reproduce it. My code is fairly simple

ICloudDirectoryEntry publicFolder = dropbox.GetFolder(cloudPath);

foreach (var fof in publicFolder)
{

      if (fof is ICloudDirectoryEntry)
      {
               ICloudDirectoryEntry cde = fof as ICloudDirectoryEntry;

               string parentFolder = cloudPath + cde.Name + "/";

               foreach (var subDirFile in cde)
               {
                    dropbox.DownloadFile(parentFolder + subDirFile.Name, localDirName);
               }
       }
       else
       {
            dropbox.DownloadFile(cloudPath + fof.Name, localFileName);
       }

}

Any help would be appreciated.

Note that I am not accessing the Root directory but a directory within the "Apps" folder
on Dropbox (i.e. I do not have full access to the Dropbox folder).

JanJunius — Sun, 14 Apr 2013 11:47:18 GMT

Hi,

solved my problem. What I had overlooked was that exception handling in Xamarin studio was enabled for all exceptions and the debugger just stopped when some internal exceptions were thrown. After changing that my app runs fine.
Embarrassing...
Sorry for this needless post

New Post: Using Sharpbox to connect to dropbox from within an (Xamarin) Android app

JanJunius — Sat, 13 Apr 2013 12:39:33 GMT

Hi,

I use Sharpbox with Xamarin for iOS and Android. The iOS version works fine, but the same code doesn't work at all in the Android version :-(

This is the code I use to get the Url the user can use to login to dropbox:

DropBoxConfiguration config = CloudStorage.GetCloudConfigurationEasy(nSupportedCloudConfigurations.DropBox) as DropBoxConfiguration;
config.AuthorizationCallBack = new Uri(callBackUrl);
requestToken = DropBoxStorageProviderTools.GetDropBoxRequestToken(config, consumerKey, consumerSecret);
DropBoxStorageProviderTools.GetDropBoxAuthorizationUrl(config, (DropBoxRequestToken)requestToken);

My app hangs when executing the third line: DropBoxStorageProviderTools.GetDropBoxRequestToken

I have a call stack like this one:

System.Security.Cryptography.X509Certificates.X509Store.Open (flags=) in
System.Security.Cryptography.X509Certificates.X509Chain.get_LMRootStore (Parameters=) in
System.Security.Cryptography.X509Certificates.X509Chain.get_Roots (Parameters=) in

Mono.Security.Protocol.Tls.Handshake.HandshakeMessage.Process (Parameters=) in
Mono.Security.Protocol.Tls.ClientRecordProtocol.ProcessHandshakeMessage (Parameters=) in
Mono.Security.Protocol.Tls.RecordProtocol.InternalReceiveRecordCallback (Parameters=) in

My app has Internet permissions, but it seems it cannot get an answer from dropbox. Where is my mistake???

I would be very thankful for any ideas…

Thanks,
Jan

New Post: Upload File into subfolders

juantar — Tue, 09 Apr 2013 12:41:57 GMT

I was able to find a workaround. In the following method in the DropBoxStorageProviderService class:

private string GetResourceUrlInternal(IStorageProviderSession session, ICloudFileSystemEntry fileSystemEntry)

Remove the calls to HttpUtilityEx.UrlEncodeUTF8, so instead of HttpUtilityEx.UrlEncodeUTF8(resourcePath), just do resourcePath.

The same needs to be done in:

public static String GetDownloadFileUrlInternal(IStorageProviderSession session, ICloudFileSystemEntry entry)

You need to remove the calls to HttpUtilityEx.UrlEncodeUTF8 and instead of url += HttpUtilityEx.UrlEncodeUTF8(dropboxPath), just use url += dropboxPath;

This worked for me even if the subfolders in the path had spaces on their names.

MSalzig — Sun, 31 Mar 2013 08:24:30 GMT

Hi,

I try to list all entries in a folder. But I get an exception SharpBoxException with message 'File not found'. I'm using a WebDav connection to LiveDrive over ssl (see following code). I have test the same WebDav connection with WebDav http://webdavnet.codeplex.com/ and works fine.

Here my code:

// Creating the cloudstorage object
CloudStorage cloudStorage = new CloudStorage();

var uri = new Uri("https://webdav.livedrive.com:443/");

var boxnetConfig = CloudStorage.GetCloudConfigurationEasy(nSupportedCloudConfigurations.WebDav, uri);


// building credentials for the service
var webDavCredentials = new GenericNetworkCredentials();

// set the information you got from the enduser
webDavCredentials.UserName = "michael.salzig@xxx.xx";
webDavCredentials.Password = "myPassword";

var storageToken = cloudStorage.Open(boxnetConfig, webDavCredentials);

var publicFolder = cloudStorage.GetFolder("/Test");

foreach (var fof in publicFolder)
{
  // check if we have a directory
  bool bIsDirectory = fof is ICloudDirectoryEntry;
  // output the info
  Console.WriteLine("{0}: {1}", bIsDirectory ? "DIR" : "FIL", fof.Name);
}

I hope I can get help from anyone.

Thanks

Hi,
I'm getting the http error code 403 while downloading a file.

```
: in AppLimit.CloudComputing.SharpBox.Common.Net.Web.WebRequestService.GetWebResponse(WebRequest request)
in AppLimit.CloudComputing.SharpBox.StorageProvider.DropBox.Logic.DropBoxStorageProviderService.CreateDownloadStream(IStorageProviderSession session, ICloudFileSystemEntry fileSystemEntry)

in AppLimit.CloudComputing.SharpBox.StorageProvider.BaseObjects.BaseFileEntryDataTransfer.Transfer(Stream targetDataStream, nTransferDirection direction, FileOperationProgressChanged progressCallback, Object progressContext)

```

The strange thing is that I can correctly login and I can display all folder and files in my dropbox account.
I got this error only after my app has entered into "production" status. When it was in test it worked perfectly.
Comments: ** Comment from web user: marcoKED2 **

An update to this issue.
The problem is the .Net framework. I had to move from version 4.0 to 4.5 of .Net framework and using a Web Site with version 4.5 the problem rise while using the 4.0 there were no problems.
Using instead a Web Application the library works fine for both versions.

jshanki — Wed, 06 Mar 2013 00:39:23 GMT

Hi,

I am currently trying to use ownCloud as my own cloud storage system. I am having a linux desktop and when I tried to use owncloud client in 64 -bit system. It is not working. So when I was searching for alternate - I got to Sharpbox and its great. First of all - thanks for creating a nice library.

Question: I am planning to use the webdav part of the library using Mono (in linux). I am finding a couple of pieces not working

When there are files in the local and not in the remote, I get a "Index out of Range".
The RemoveMissingFiles flag seems not to work for local to remove I.e. when I delete a file from local it is not removing from remote. I did not want the other way around (Delete file in remote and remove in local).

So can I make those changes and make it work only for Mono. Please let me know and I would be using only WebDav.

Thanks
Shankara Narayanan.
