I'm trying to convert the sample C# code provided my echosign in VB.net for use within our applications. Specifically the SendDocument method.
Has anyone out there done this already?
The API is throwing back an error message "Fault: java.lang.NullPointerException" when ever i call it.
Here is the converted function:
Public Shared Function SendDocument(ByVal apiKey As String, ByVal file As Byte(), ByVal recipientEmailAddress As String, ByVal fileName As String, ByVal message As String, ByVal expireDays As Int32) As String
Try
Dim ES As EchoSignDocumentService13 = New EchoSignDocumentService13()
ES.Url = "https://secure.echosign.com/services/EchoSignDocumentService13"
Dim recipients(1) As String
recipients(0) = recipientEmailAddress
Dim localSenderInfo As com.echosign.secure.SenderInfo = Nothing
Dim echoFileInfo(1) As com.echosign.secure.FileInfo
echoFileInfo(0) = New com.echosign.secure.FileInfo()
With echoFileInfo(0)
.fileName = fileName
.mimeType = "application/msword"
.file = file
End With
Dim echoDocumentInfo As com.echosign.secure.DocumentCreationInfo = New com.echosign.secure.DocumentCreationInfo()
With echoDocumentInfo
.tos = recipients
.name = fileName
.message = message
.fileInfos = echoFileInfo
.signatureType = SignatureType.ESIGN
.signatureFlow = SignatureFlow.SENDER_SIGNATURE_NOT_REQUIRED
.daysUntilSigningDeadline = expireDays
End With
Dim echoKey() As DocumentKey
echoKey = ES.sendDocument(apiKey, localSenderInfo, echoDocumentInfo)
Return echoKey(0).documentKey.ToString()
Catch ex As Exception
Return "EchoError: " & ex.Message
End Try
End Function
Any help is most welcome
Thanks

I can't find anywhere where I have a problem sending emails, it only happens to some users, while for others everything normally works with this code:
Dim service As New ExchangeService(requestedServerVersion:=ExchangeVersion.Exchange2013_SP1)

service.Url = New Uri("https://mail.server.com/ews/exchange.asmx")
'Add a valid user credentials
service.Credentials = New WebCredentials("someuser", "somepasw", "somedomain")
'To address the SSL challenge
ServicePointManager.ServerCertificateValidationCallback = New RemoteCertificateValidationCallback(AddressOf ValidateCertificate)
Try 'Create new message object and set properties required to send a mail
Dim sender As New Microsoft.Exchange.WebServices.Data.EmailAddress
Dim message As EmailMessage = New EmailMessage(service)
message.Subject = Betreff
message.Body = MailText
If Absender <> "" Then
Absender = Absender
sender.Address = Absender
message.From = sender
End If
For Each adr As String In Mailadressen
message.ToRecipients.Add(adr)
Next
For Each cc As String In CCAdressen
message.CcRecipients.Add(cc)
Next
For Each a As String In Anhang
message.Attachments.AddFileAttachment(a)
Next
message.SendAndSaveCopy()
Catch ex As Exception
MessageBox.Show(vbNewLine & "" & vbNewLine & String.Format("Error: {0}", ex.StackTrace))

I have a functionality which saves the information from a webform to the database, which is working fine.
This is my code for save functionality in Onspec.aspx.vb page
Public Sub SaveClick(ByVal sender As Object, ByVal e As System.EventArgs)
If Not Page.IsValid Then
litMessage.Text = ""
Exit Sub
End If
Try
Dim sName As String = ""
With EmployerCandidate
.employerid = Master.Employer.ID
.employeruserid = 0
Try
.CVID = DocId
Catch
End Try
.Name = uxName.Text
.SurName = uxSurname.Text
Try
.PostCode = uxPostcode.Text
Catch ex As Exception
End Try
.Email = uxEmail.Text
Try
.MobileNo = uxMobileNo.Text
Catch ex As Exception
End Try
.OnSpec = True
.OnSpecType = uxOnSpecCategory.SelectedItem.Text
.Source = uxSourceID.SelectedItem.Text
.LastEmployer = uxEmployer.Text
.LastJobTitle = uxJobtitle.Text
.Profile = uxProfile.Text.Trim
End With
' email()
ResetForm()
panForm.Visible = False
panUpload.Visible = True
uxSubmit.Visible = False
uxUpload.Visible = True
litMessage.Text = "Thank you for submitting your details! We'll be in touch when appropriate vacancy arises. <a href='#' onclick='parent.$.colorbox.close()'>Close</a>"
UploadPanel.Visible = False
Response.Redirect("onspec-complete.aspx?e=" & Master.Employer.ID)
Catch ex As Exception
litMessage.Text = Core.Helper.FancyMessage("Error as occurred - " & ex.Message.ToString, "ERROR")
End Try
End Sub
Now, I want to send emails along with saving the data in the database so I added the following lines of code before ResetForm().
Dim specmatch As DataRow = DB.GetRow("SELECT TOP 1 name,email,password FROM [user] usr JOIN employeruser empUsr ON usr.id = empUsr.userid WHERE empUsr.empusertype = 1 AND empUsr.employerid = #eid ", DB.SIP("eid", LocalHelper.UserEmployerID))
If my query returns a value then I want to send email by calling the email function.
If specmatch IsNot Nothing Then
email()
End If
But in this line of code the employerid value is sometimes empty. It can't pick the id therefore it is returning an empty row. And therefore it's not calling the email function.
This id is the same as
.employerid = Master.Employer.ID
But if I replace the LocalHelper.UserEmployerID with Master.Employer.ID the form gives an error:
Object reference not set to an instance of an object.
employerid is an integer value.
I have also tried to add the following lines of code in this page(Onspec.aspx.vb)
Public ReadOnly Property EmployerId() As Integer
Get
Return Master.Employer.ID
End Get
End Property
But I get the same error:
Object reference not set to an instance of an object.
The above lines of code does not make any difference.
So I replaced Master.Employer.ID with LocalHelper.UserEmployerID
Where in localhelper.vb file (under appcode folder) it is determining employerid from the website with following lines of code.
Public Shared Function UserEmployerID() As Integer
If HttpContext.Current.Items("lh_useremployerid") Is Nothing Then
If LocalHelper.UserTypeCode = "e" Then
HttpContext.Current.Items("lh_useremployerid") = Core.DB.GetInteger("SELECT employerid FROM employeruser WHERE userid = " & LocalHelper.UserID)
Else
HttpContext.Current.Items("lh_useremployerid") = 0
End If
End If
Return HttpContext.Current.Items("lh_useremployerid")
End Function
These lines of code has been used in many places and works perfectly fine. In this case as well, it was working fine last Friday and now it's not. There was no changes made.
This is my email function

So...i am trying to use the update feature inside Visual Basic to update a files contents and metadata. Use the first piece of code to call it. However the code runs but does not update the file inside my drive and gives 0 errors. I am not sure what is wrong with the code since i have another piece of code which updates just the metadata just fine. Any help would be appreciated!
bob.updateFile(bob.service, "0Bzqp8R7eFke2aHZqZHdYZ2RpYjg", "listbox.txt", "Test #2", ".txt", "meme.txt ", True)

Try
' First retrieve the file from the API.
Dim file As File = service.Files.Get(fileId).Execute
' File's new metadata.
file.Title = newTitle
file.Description = newDescription
file.MimeType = newMimeType
' File's new content.
Dim byteArray() As Byte = System.IO.File.ReadAllBytes(newFilename)
Dim stream As System.IO.MemoryStream = New System.IO.MemoryStream(byteArray)
'Send the request to the API.
Dim request As FilesResource.UpdateMediaUpload = service.Files.Update(file, fileId, stream, newMimeType)
request.NewRevision = newRevision
request.Upload()
Dim updatedFile As File = request.ResponseBody
Return updatedFile
stream.Close()
Catch e As Exception
MessageBox.Show(("An error occurred: " + e.Message))
End Try
End Function

This is the working code for the metadata
Public Function updateMetadata(ByVal service As DriveService, ByVal fileId As String, ByVal newTitle As String, ByVal newDescription As String, ByVal newMimeType As String, ByVal newRevision As Boolean) As File
Try
' First retrieve the file from the API.

Dim updatedFile As File = request.Execute
Return updatedFile
Catch e As Exception

Hey guys thanks for the help!
Heres the working code, the issue was the mime type doesn't have to be changed!

I have an MS Access database which now requires me to 'attach' documents to it. My intention is to store the documents on Google Drive and have a link on the database for users to retrieve the documents.
As there are many users spread through different cities, it is not practical to require them to have synced Google Drive folders. All the users will need the ability to upload to the database/GD so my intention is to have a separate Google account for the database - with its own login details.
example:
User clicks button to upload file
Save as dialog box appears and user selects file
Database logs into its Google Drive and uploads selected file
Lots of problems with this though, the main one being that Google Drive does not support VBA.
If the user is logged into their own Gmail account, that will probably be another issue.
I came across this code for vb.net on another site.

It was suggested that the IE library could be utilised to log into the Google Drive and the API calls made from the above to upload. I don't know how to do this. Somewhere else it was mentioned that a 'COM wrapper' may be suitable. I don't have experience with any coding other than VBA (self taught) so am struggling to understand what the next step should be.
If anyone has done something similar or can offer any advice, I would be grateful to hear from you.
This thread might be dead now but if you are working with forms in your database and the user needs to be attaching the files to a particular record displayed in a form with a unique identification number then this is definitely possible but you would have to do it in an external application written in .NET I can provide you with the necessary code to get you started, vb.net is very similar to VBA.
What you would need to do is create a windows form project and add references to Microsoft access core dll and download the nugget package for google drive api from nugget.
Imports Google
Imports Google.Apis.Services
Imports Google.Apis.Drive.v2
Imports Google.Apis.Auth.OAuth2
Imports Google.Apis.Drive.v2.Data
Imports System.Threading
Public Class GoogleDriveAuth
Public Shared Function GetAuthentication() As DriveService
Dim ClientIDString As String = "Your Client ID"
Dim ClientSecretString As String = "Your Client Secret"
Dim ApplicationNameString As String = "Your Application Name"
Dim secrets = New ClientSecrets()
secrets.ClientId = ClientIDString
secrets.ClientSecret = ClientSecretString
Dim scope = New List(Of String)
scope.Add(DriveService.Scope.Drive)
Dim credential = GoogleWebAuthorizationBroker.AuthorizeAsync(secrets, scope, "user", CancellationToken.None).Result()
Dim initializer = New BaseClientService.Initializer
initializer.HttpClientInitializer = credential
initializer.ApplicationName = ApplicationNameString
Dim Service = New DriveService(initializer)
Return Service
End Function
End Class
This code will authorise your drive service then you create a Public Shared Service As DriveService under your imports that can be used from any sub or function then call this function on your form load event like
Service = GoogleDriveAuth.GetAuthentication
Add a reference to your project to Microsoft Access 12.0 Object Library or whatever version you have
Then this piece of code will look at the form you want to get the value of the record no from and upload a file to your choice of folder

Hopefully this helps you make a start I am 100% convinced this is achievable as I have already done this for my manager.
This reply might be late but just wanna share one of the approach!
I have done this successfully with VBA and the demo link is here
http://www.sfdp.net/thuthuataccess/demo/democAuth.rar?attredirects=0&d=1
With this, you can upload, download or delete a file with your GoogleDrive in Access..
Just Wininet + WinHTTP enough

I'm working on an WindowsPhone 8 app that stores and reads it's data from its IsolatedStorage.
I'm using Visual Basic.NET and LINQ to XML.
There's no problem with loading/saving the data, but I've got a serious issue with replacing an XElement with [***XElementListName*].FirstOrDefault().ReplaceWith([NewXElementName])**.
It throws an System.AccessViolationException, but only if it's supposed to find and replace the data bound to the FIRST item in a LongListSelector, also the first of that element in the XML file. Editing any other item works fine thou.
Here's the code from the routine that is supposed to replace the data.
Dim Accounts = From el In XMLData.<accounts>.<account> Where _
el.Attribute("title").Value = oiTitle And _
el.Attribute("uname").Value = oiName And _
el.Attribute("pass").Value = oiPass And _
el.Attribute("site").Value = oiSite And _
el.Attribute("description").Value = oiDesc _
Select el
Dim acc As XElement = Accounts.FirstOrDefault()
If acc.Equals(Nothing) Then
MessageBox.Show("Error while saving edited account. Account not found.", "Account not found", MessageBoxButton.OK)
Exit Sub
End If
Dim tmpstr As String = acc.Attribute("title").Value + _
acc.Attribute("uname").Value + _
acc.Attribute("pass").Value + _
acc.Attribute("site").Value + _
acc.Attribute("description").Value
'Does this during debug to confirm that the replace is performed on the correct item.
MessageBox.Show(tmpstr, "Info about first item", MessageBoxButton.OK)

' This code throws the exception when performing on the first item from the LongListSelector
Accounts.FirstOrDefault().ReplaceWith(acc)
I've searched and tried to figure it out by looking at the LINQ to XML documentation, but it lacks usable examples. Also checked this: How can I update/replace an element of an XElement from a string?
So, does anyone sit on any knowledge I could use to solve this?
If there's some code you'd like to see, just tell me, it's pretty ugly though.
EDIT: Omitted the Accounts.FirstOrDefault().ReplaceWith(acc) line, and it works just fine. Saves everything as it should. Also rewrote some code, here's the new one, and all the related code in that sub.
Public Sub EditAccount(ByVal OldInfo As AccountViewModel, ByVal NewInfo As AccountViewModel)
Dim IsStore As IsolatedStorageFile = IsolatedStorageFile.GetUserStoreForApplication()
Dim File As New IsolatedStorageFileStream("Data.xml", FileMode.Open, IsStore)
Dim XMLData As XElement = XElement.Load(File)
Dim oiTitle As String = OldInfo.Title
Dim oiName As String = OldInfo.Username
Dim oiPass As String = OldInfo.Password
Dim oiSite As String = OldInfo.Site
Dim oiDesc As String = OldInfo.Description
Try
Dim Accounts = From e In XMLData.<accounts>.<account> Where ( _
e.Attribute("title").Value = oiTitle And _
e.Attribute("uname").Value = oiName And _
e.Attribute("pass").Value = oiPass And _
e.Attribute("site").Value = oiSite And _
e.Attribute("description").Value = oiDesc)
Select e Take 1
Dim Account As XElement = Accounts.FirstOrDefault()
If Account.Equals(Nothing) Then
MessageBox.Show("Error while saving edited account. Account not found.", "Account not found", MessageBoxButton.OK)
Exit Sub
End If
Dim tmpstr As String = Account.Attribute("title").Value + _
Account.Attribute("uname").Value + _
Account.Attribute("pass").Value + _
Account.Attribute("site").Value + _
Account.Attribute("description").Value

Account.Attribute("uname").SetValue(NewInfo.Username)

Account.Attribute("site").SetValue(NewInfo.Site)

File.Close()
IsStore.DeleteFile("Data.xml")
File = New IsolatedStorageFileStream("Data.xml", FileMode.Create, IsStore)
XMLData.Save(File)
File.Close()
Catch ex As Exception
MessageBox.Show(ex.ToString)
