请教高手关于水晶报表WEB服务的问题？急……

[liufan2005]

我在web服务项目中添加了现有的水晶报表，并将它转换为了WEB服务发布，可是在客户端WINFORM中调用时却出现了一个“数据库登陆”的对话框，服务器名称是DataSet1(只读),要求输入用户名和密码，我输入SA和密码后，还是无法连接水晶报表。怎么回事？？？？？？？？

需要在显示报表前添加数据库登录信息，例如以下代码：

// Create a new instance of the tablelogoninfos class which contains
//the tablelogoninfo objects for each table in the report
crTableLogonInfos = new TableLogOnInfos();

//Create a new instance of the TableLogonInfo class which contains
//the connection information for each table
crTableLogonInfo = new TableLogOnInfo();

//Set the connection properties
//Note: this sample report connects to the SQL Server sample Pubs database
//If you have access to SQL server, enter in your values for the ServerName,
//UserID and Password properties to connect. The report included with this
//sample application connects using OLE-DB and SQL authentication.
crConnectionInfo = new ConnectionInfo();
crConnectionInfo.ServerName = "rcon1";
crConnectionInfo.DatabaseName = "Pubs";
crConnectionInfo.UserID = "vantech";
crConnectionInfo.Password = "vantech";

//apply the connection information to each table. If the TableName is not specified, the
//logon to the database will fail. Once the tablename and connection information have been
//set for each table object, it is added to the TableLogonInfos collection using the Add method.
crTableLogonInfo.ConnectionInfo = crConnectionInfo;
crTableLogonInfo.TableName = "authors";
crTableLogonInfos.Add(crTableLogonInfo);

//Pass the table information to the logoninfo property of the viewer
CrystalReportViewer1.LogOnInfo = crTableLogonInfos;

CrystalReportViewer1.ReportSource = crReportDocument;
