使用GPConnNet.dll的SQL Server連接

Question

我正在嘗試使用當前從GP登錄的憑據連接到動態GP SQL Server數據庫。 （對於上下文http://blogs.msdn.com/b/developingfordynamicsgp/archive/2008/10/02/why-does-microsoft-dynamics-gp-encrypt-passwords.aspx）

使用從GPConnNet.dll文檔中提供的代碼我應該能夠獲得連接，但對於非sa用戶無法這樣做，sa和dynsa可以正常工作。我收到一個登錄失敗的sql server錯誤。

SqlConnectionStringBuilder cb = new SqlConnectionStringBuilder(connectionString); 
SqlConnection sqlConn = new SqlConnection(); 
if (sqlConn.State != ConnectionState.Open) 
{ 
    GPConnection.Startup(); 
    var gpconn = new GPConnection(); 
    gpconn.Init(<Key1>, <Key2>); 
try 
{ 
    sqlConn.ConnectionString = string.Format("database={0}", cb.InitialCatalog); 
    gpconn.LoginCompatibilityMode = false; 
    gpconn.Connect(sqlConn, cb.DataSource, cb.UserID, cb.Password); 
    if (gpconn.ReturnCode != 1) 
     throw new AuthenticationException("Could not authenticate with the GP credentials."); 
} 
catch (System.Runtime.InteropServices.SEHException) 
{ 
    throw new AuthenticationException("Could not authenticate with the GP credentials."); 
} 
} 

連接字符串中的信息來自Microsoft Dexterity工具包。

public class GPUser 
{ 
    public readonly static string DataBase = Dynamics.Globals.IntercompanyId.Value; 
    public readonly static string UserID = Dynamics.Globals.UserName.Value; 
    public readonly static string Password = Dynamics.Globals.SqlPassword.Value; 
    public readonly static string DataSource = Dynamics.Globals.SqlDataSourceName.Value; 
    public readonly static string ApplicationName = string.Format("{0}{1}", App.ProductName, "(gp)"); 
    public static string Server 
    { 
     get 
     { 
      //Returns the Server from the ODBC DSN 
     } 
    } 
    public static SqlConnectionStringBuilder ConnectionString 
    { 
     get 
     { 
      return new SqlConnectionStringBuilder 
      { 
       DataSource = Server, 
       UserID = UserID, 
       Password = Password, 
       ApplicationName = ApplicationName, 
       InitialCatalog = DataBase 
      }; 
     } 

    } 
} 

用戶需要什麼嗎？我錯過了GPConnection代碼中的某些內容嗎？

謝謝

此類將檢索連接所需的正確數據。

public class GPUser 
{ 
    public readonly static string DataBase = Dynamics.Globals.IntercompanyId.Value; 
    public readonly static string UserID = Dynamics.Globals.UserId.Value; 
    public readonly static string Password = Dynamics.Globals.SqlPassword.Value; 
    public readonly static string DataSource = Dynamics.Globals.SqlDataSourceName.Value; 
    public readonly static string ApplicationName = string.Format("{0}{1}", App.ProductName, "(gp)"); 
    public static SqlConnectionStringBuilder ConnectionString 
    { 
     get 
     { 
      return new SqlConnectionStringBuilder 
      { 
       DataSource = DataSource, 
       UserID = UserID, 
       Password = Password, 
       ApplicationName = ApplicationName, 
       InitialCatalog = DataBase 
      }; 
     } 

    } 
    public readonly static short CompanyId = Dynamics.Globals.CompanyId.Value; 
    public readonly static DateTime UserDate = Dynamics.Globals.UserDate.Value; 
} 

傳遞GPUser.ConnectionString這個代碼將創建，您可以使用連接到GP數據庫的有效SQLConnection對象。

SqlConnectionStringBuilder cb = new SqlConnectionStringBuilder(connectionString); 
SqlConnection sqlConn = new SqlConnection(); 
if (sqlConn.State != ConnectionState.Open) 
{ 
    GPConnection.Startup(); 
    var gpconn = new GPConnection(); 
    gpconn.Init(<Key1>, <Key2>); 
    try 
    { 
     sqlConn.ConnectionString = string.Format("database={0}", cb.InitialCatalog); 
     gpconn.LoginCompatibilityMode = false; 
     gpconn.Connect(sqlConn, cb.DataSource, cb.UserID, cb.Password); 
     if (gpconn.ReturnCode != 1) 
      throw new AuthenticationException("Could not authenticate with the GP credentials."); 
    } 
    catch (System.Runtime.InteropServices.SEHException) 
    { 
     throw new AuthenticationException("Could not authenticate with the GP credentials."); 
    } 
}
