使用VB.net创建SQL连接

Question

我正在尝试将VB.net连接到SQL服务器以获取一些信息，我从Microsoft Technet获得了连接脚本但是它为用户提供了登录失败：domain \ user。虽然该帐户具有dbowner权限，但也是一个服务帐户。我在同一台机器上成功创建了powershell和Sql数据库之间的连接。

Imports System.Data.SqlClient

Public Class Form1
    Inherits System.Windows.Forms.Form
    'Create ADO.NET objects.
    Private myConn As SqlConnection
    Private myCmd As SqlCommand
    Private myReader As SqlDataReader
    Private results As String

    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load

        'Create a Connection object.
        myConn = New SqlConnection("Initial Catalog=VMdbInventory;" & _
                "Data Source=MONITORING\SQLEXPRESS;Integrated Security=SSPI;")

        'Create a Command object.
        myCmd = myConn.CreateCommand
        myCmd.CommandText = "SELECT * from vmonhost"

        'Open the connection.
        myConn.Open()

        myReader = myCmd.ExecuteReader()

        'Concatenate the query result into a string.
        Do While myReader.Read()
            results = results & myReader.GetString(0) & vbTab & _
                    myReader.GetString(1) & vbLf
        Loop
        'Display results.
        MsgBox(results)



        'Close the reader and the database connection.
        myReader.Close()
        myConn.Close()



    End Sub
End Class

任何想法我在这里缺少什么？
