I just tried to use the SMTP-Socket on a XOJO- Web App.
What I did is: I created a class with a super SMTPSocket, placed an instance of this into a webdialog. Even without any program on this webdialog, when I start the compiler I got the following errormessage (It was in german, so I try to translate it 
):
Position: webdialog.mysocket.name Layout (PropertyName)
Problem: Parameters are not kompatible with this function name
What was my mistake?

OK - I solved the problem by myself …
I have to place an instance of that class to the related webpage where an instance of the webdialog is placed …
Now it runs fine and send mails 
How did you did it, i cant connect to the server
the main information are:
SMTPSocket.address = “smtp.gmail.com”
SMTPSocket.port = 587
SMTPSocket.username = “anaccounttoconnect@anaccounttoconnect.com”
SMTPSocket.password = “apassword”
SMTPSocket.connect
if SMTPSocket.isconnected the
msgbox “SI”
else
msgbox “No”
ned if
i got “No”
