in a ASP.Net 2.0 web Application, to get a connection string from Web.config, you would write:
ConfigurationManager.ConnectionStrings("DB").ConnectionString

trying to do the same in a Windows application, would give you the error :
Name 'ConfigurationManager' is not declared
even you did import "System.Configuration"...

well, after searching i found that you need to add reference to "System.Configuration.dll" : under Project > Add refrence > .Net > select System.Configuration

Since Jmail 4.5, you can send UTF-8 Text in Email Subject
V4 would Send UTF-8 Body , but the Subject will be corrupted
Dim JMailObj As New jmail.SMTPMail
JMailObj.ServerAddress = ServerAddress
JMailObj.Silent = True
JMailObj.Logging = True
JMailObj.Charset = "utf-8"
JMailObj.ContentType = "text/html"
JMailObj.Sender = Sender
JMailObj.Subject = Subject
JMailObj.AddRecipient Email
JMailObj.Body = Message
JMailObj.Execute
Set JMailObj = Nothing
