yo lo e echo de dos formas con un slqcommand:
Dim myConnection As SqlConnection
myConnection = New SqlConnection(ConfigurationSettings.AppSettings("C onnectionStringSql"))
Dim myCommand As New SqlCommand("usuarios_repetidos", myConnection)
myCommand.CommandType = CommandType.StoredProcedure
myCommand.Parameters.Add("@us", usu.Text)
myCommand.Parameters.Add("@psw", psw_usu.Text)
Y tambien lo e echo con sqldataadapter:
Dim con As New SqlConnection(ConfigurationSettings.AppSettings("C onnectionStringSql"))
Dim com As New SqlDataAdapter("lleno_statusl", con)
Dim adaptador As New DataSet
com.SelectCommand.CommandType = CommandType.StoredProcedure
com.SelectCommand.Parameters.Add("@valida", comparars)
com.SelectCommand.Parameters.Add("@id_user", comparars)
