This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
Or you can force the function to take only non null parameter value as the following
Public Sub SendEmail(ByVal Mail_To As String)
If IsNothing( Mail_To ) Then
Throw New ArgumentNullException( "Mail_To" )
End If
oMsg.To = Mail_To
.......
And overload the function, like so
Public Sub SendEmail()
SendEmail( "pern@dragonsworkshop.com"
End Sub
This is C# style :o)
Public Sub SendEmail(ByVal Mail_To As String)
If IsNothing( Mail_To ) Then
Throw New ArgumentNullException( "Mail_To" )
End If
oMsg.To = Mail_To
.......
And overload the function, like so
Public Sub SendEmail()
SendEmail( "pern@dragonsworkshop.com"
End Sub
This is C# style :o)

Thanks thats what i was looking for
Public Sub SendEmail(Optional ByVal Mail_To As String = "pern@dragonsworkshop.com"
End Sub
Any parameters that follow Mail_To must also be declared as Optional as well.
