You're going to step too far with this line:
command = New SqlCommand(Query.Text, mysqlconn).ExecuteNonQuery

Instead of setting up your command object and storing it in the command variable you are trying to place the result of exectuting the command there.
Which can't be done of course, it's the wrong type.

Try:

command = New SqlCommand(Query.Text, mysqlconn)
Integer result = command.ExecuteNonQuery
