Emailer threading

Download and extract the attached solution. Open the Form1 and set the properties, then see what result you get from this.

Same error message.

An unhandled exception of type 'System.Net.Mail.SmtpException' occurred in System.dll

Additional Information: The SMTP server requires a secure connection or the client is not authenticated. The server response was: Authentication required


thanks!!

When it stops at the exception, hover over "Client" and see if UseDefauleCredentials is False and Credentials are set to something.

I start with visual studio so I do not understand everything but if you want one could use team viewer you could see for yourself.

I'm not able to do a TeamViewer session today, but if you hover the mouse cursor over "client" on the line of code in which it stopped at, a window will popup with all of the properties and their values. Scroll through that list and look for UseDefauleCredentials and Credentials to see what value they have.

[sebas]

 Credentials = {System.Net.NetworkCredential}         

UseDefaultCredentials = False

What happens if you use the code in reply #3? Assuming you are using Gmail, just input your specific info.

[sebas]

I do not understand what you mean?

[Phrog30]

Go to reply #3 in this thread and copy the code, paste it in your application and try it, obviously using your email settings.

[sebas]

I did it and it works very well its the emailer function which wants not to work with the same email setting.

[Phrog30]

Ok, now I don't understand. That code is an emailer.

[Archie]

I have tried this using the emailer component and the using the code you posted, in both cases I get the same message from Gmail:

"The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required."

I even went into my Gmail settings and turned on the "Allow less secure apps" setting, but it still does not work.

[sebas]

I managed to run the emailertest that you made me try at Reply # 15 by modifying the code as follows:

  Client.Credentials = NewSystem.Net.NetworkCredential( m_SmtpLoginUserName , m_SmtpLoginPassword)
 

I modify the line so high by:

  Client.Credentials = NewSystem.Net.NetworkCredential ("sebastienduhaime@gmail.com", "xxxxxxxx")

But when I made the same change in the anvanced HMI emailer its not working.


Thank you very much for your help it is very appreciated!!!

[sebas]

Did you test with anything other than gmail and did it work?

[Archie]

I finally got to the bottom of this problem. It will be fixed in the next version.
