用戶登錄失敗 - Visual Basic和SQL服務器2008

我對視覺基礎熊很陌生。我已經使用visual studio 2010和SQL Server 2008創建了一個Windows應用程序。我在嘗試執行插入SQL命令時遇到了登錄問題。我給了用戶一個所有者特權。這是我正在使用的連接字符串。用戶登錄失敗 - Visual Basic和SQL服務器2008

我注意到兩件事。首先，錯誤消息是說您嘗試登錄的用戶是'UserId'。這真的是你的用戶的名字嗎？我的猜測是，事實並非如此。其次，您似乎錯誤地定義了連接字符串。

連接字符串應該是這樣的：

Server=myServerAddress;Database=myDataBase;User Id=myUsername;Password=myPassword;

此外，我會嘗試登錄的用戶名和密碼，您首先使用在連接字符串中您的SQL Server。這將允許您使用登錄來調整任何必要的權限，而無需啓動和停止您的應用程序。
