I have an ASP.NET 4.5 application with a separate class library for accessing the Google analytics data. Every try to use the common methods (loading the certificat from .p12 file) ends in an "internal error" (the file will be found!) in 3rd line (Dim certificat...)
Dim scopes As String() = New String() {AnalyticsService.Scope.Analytics}
Dim serviceAccountEmail = "info#xxx.biz"
Dim certificate = New X509Certificate2(System.Web.HttpContext.Current.Server.MapPath("Certificates/MyDashboard-b335c24b1a76.p12"), "notasecret", X509KeyStorageFlags.Exportable)
Dim credential = New ServiceAccountCredential(New ServiceAccountCredential.Initializer(serviceAccountEmail) With {.Scopes = scopes}.FromCertificate(certificate))
Dim service = New AnalyticsService(New BaseClientService.Initializer() With { _
.HttpClientInitializer = credential, _
.ApplicationName = "MyDashboard" _
})
Dim MyRequest As DataResource.GaResource.GetRequest = service.Data.Ga.Get("ga:44582845", "2016-01-01", "2016-01-01", "ga:sessions")
MyRequest.MaxResults = 1000
Dim MyResult As GaData = MyRequest.Execute()

Is there any possibility to access the analytics data without the certificate (I think it was in former times)?

Which part I am committing mistake and need to correct it?
The reason it fails is using the empty constructor without the mail settings to match:
MailMessage mm = new MailMessage();
The empty constructor relies on:
<system.net>
<mailSettings>
<smtp from="report#company.com" />
</mailSettings>
</system.net>
in your app or web.config file. So either use the constructor that expects a from and to address, or add that node to your app/web.config file.
I firmly believe this is a bug in the .Net framework, because we were able to create new MailMessage() objects and then assign the "from" later on, but in .Net 4.0 and under certain conditions—which I still don't fully understand—this fails. I welcome being corrected of course, but for now, this seems like an oversight.
So some of our customers never encountered this issue, but to fix it we had to add that dummy setting to the web.config files.
I had a similar problem with getting [FormatException: The specified string is not in the form required for an e-mail address.] too. My problem was with this code:
void SendMail(string destinationEmail)
MailMessage message=new MailMessage("mytestmail#test.com",destinationEmail);
SmtpClient mailClient = new SmtpClient("mail.test.com", 587);
mailClient.Credentials = new System.Net.NetworkCredential("mytestmail", "pswd");
try{
mailClient.Send(mail);
}
catch (Exception ex){...}
As you can see I just tried and caught only sending part. But this problem was thrown from MailMessage constructor. I would have never guessed that a constructor would throw an exception. So I just tried this code independently:
MailMessage mail = new MailMessage("test", "test");
The result of this code is [FormatException: The specified string is not in the form required for an e-mail address.]. If you try this:
MailMessage mail = new MailMessage("", "");
you'll get ArgumentException: The parameter 'from'(or 'to') cannot be an empty string.
So what you need to do in these kind of cases is you include the MailMessage construction part in the try catch block too and make sure that the exception you catch covers exception types that MailMessage constructor might throw, in this particular case, FormatException. Although I hate cathcing the Exception class, in this case it seems to be a perfect fit.
I have an issue I have been trying to fix since this morning (now over 8h). I got the facebook cookie contents, found the auth token which works fine on its own in the browser
https://graph.facebook.com/me?access_token=201856003211297|2.AQAHJg3GugHIHhec.3600.1314442800.1-100002411647354|RAylZSUax4pdKcIt--QruS-Qcgc
But
Whenever I try to get the user information, the web-page crashes down very nicely with the error below.
I have tried to read from the page using web request:
'Dim inputFile As String = "https://graph.facebook.com/me?access_token=" & access_token
'Dim sDiskFile As String = "auth.txt"
'Dim _wrequest As WebRequest = WebRequest.Create(inputFile)
'Dim _wresponse As WebResponse
'_wresponse = _wrequest.GetResponse()
'Dim _stream As Stream = _wresponse.GetResponseStream()
'Dim oReader As New StreamReader(_stream, Encoding.ASCII)
And it crashed with the same error. I decided to give the Facebook SDK 5 a go and the same error is happening:
Dim access_token As String = GetFacebookTokenFromCookie()
If access_token = "" Then
litUser.Text = "<fb:login-button perms='email'>Login with Facebook</fb:login-button>"
Else
Dim app As New DefaultFBApp
Dim _ctx As New FacebookWebContext(app)
Dim fb As New Facebook.FacebookClient(app)
fb.AccessToken = access_token
Dim parameters As New Dictionary(Of String, Object)()
parameters("fields") = "id,name"
Dim result As Object = fb.Get(parameters)
Dim id = result.id
Dim name = result.name
Dim firstName As String = result.first_name
Dim lastName = result.last_name
Dim link = result.link
Dim username = result.username
Dim gender = result.gender
Dim male = result.locale
litUser.Text = "Welcome " & firstName
End If
DefaultFBApp is:
Public Class DefaultFBApp
Implements Facebook.IFacebookApplication
With all the must-implement fields added in and the api key and secret filled in.
Same error:

I have a strange thing going on with the .net fileupload control.
If I remote desktop to the server that houses the web app and db server, I am able to upload files and store them into a varbinary(max) column.
However, when clients connect to the web server from their desktop, then can do all the things they need to such as browsing web pages, fill out forms that store/save data to the database, etc.
However, when they try to upload a pdf to the sever, the following exception occurs:
The web app uses .net 3.5, the db is sql 2005, and code is c#. And insights would be welcomed. Code and Exception below.
Any insights will be welcomed.

That error indicates you're trying to store too much data in a database field, like trying to store a filename of length 200 in a field that's varchar(100). What are the capacites for the other table columns and what are the lengths of the content you're trying to store in them?
Try commenting a column one by one and re-execute the code, it seems you have defined a column with less size, and trying to store data which is causing this error.
can you please see the column size defined and make sure all the columns are capable to store the data for the file?
