tengo el siguiente módulo y me gustaría probar la conexión. ¿Cómo pruebo si la conexión funciona? ¿puedes ser muy específico con su respuesta:¿cómo puedo probar si estoy conectado a sql DB a través de vb.net?
Imports System.Data.SqlClient
Module Module1
Sub Main()
' Create a new SqlConnectionStringBuilder and
' initialize it with a few name/value pairs:
Dim builder As New SqlConnectionStringBuilder(GetConnectionString())
' The input connection string used the
' Server key, but the new connection string uses
' the well-known Data Source key instead.
Console.WriteLine(builder.ConnectionString)
' Pass the SqlConnectionStringBuilder an existing
' connection string, and you can retrieve and
' modify any of the elements.
builder.ConnectionString = _
"server=http://sql.example.com;user id=******;" & _
"password=***********;"
' Now that the connection string has been parsed,
' you can work with individual items.
Console.WriteLine(builder.Password)
builder.Password = "[email protected]"
builder.AsynchronousProcessing = True
' You can refer to connection keys using strings,
' as well. When you use this technique (the default
' Item property in Visual Basic, or the indexer in C#)
' you can specify any synonym for the connection string key
' name.
builder("Server") = "."
builder("Connect Timeout") = 1000
' The Item property is the default for the class,
' and setting the Item property adds the value to the
' dictionary, if necessary.
builder.Item("Trusted_Connection") = True
Console.WriteLine(builder.ConnectionString)
Console.WriteLine("Press Enter to finish.")
Console.ReadLine()
End Sub
Private Function GetConnectionString() As String
' To avoid storing the connection string in your code,
' you can retrieve it from a configuration file.
Return "Server=(local);Integrated Security=SSPI;" & _
"Initial Catalog=AdventureWorks"
End Function
End Module
por lo tanto, el simple hecho de abrir una conexión es verificar que se puede conectar a ella – PsychoData
