在CrystalReports中登录数据库 [英] Login to Database in CrystalReports

问题描述

我使用CrystalReports创建了报告，添加了四个Access数据库连接。



我的要求是，我安装它之后永远不应该提示UserID和密码在客户端的计算机上。



我也在报告中使用了参数。



我知道关于如何传递登录凭证设计时间但不确定如果在客户端PC安装后它会再次提示。



我也试过

I have created Reports using CrystalReports adding four Access Database Connections.

My requirement is, It should never prompt for UserID and Password After I install It on Client's Computer.

I have also used parameters in Reports.

I know about how to pass login credentails design time but not sure If It will prompt again after Installation at Client PC.

I also Tried

CrystalDecisions.Shared.ConnectionInfo

并且成功了，但是当尝试使用来自多个数据库的报告时失败了。

and went succeed, but failed when tried with report from multiple databases.

推荐答案

好吧，你还没有真正问过一个问题。你提供的代码......那是什么？你在哪里用它？这是一个网络应用程序？窗户形成？所有这些信息都可以帮助我们。



我能提供的唯一建议是研究CrystalReportDocument的.SetDataSource。



并此处 [ ^ ]是一篇MSDN文章关于使用DataSourceConnections类进行数据库登录。



希望它有所帮助。

Well, you haven't really asked a question. And the code you supplied...What is that? Where are you using it? Is this a web app? A windows forms? All of this information will help us help you.

The only advice I can supply is to research the CrystalReportDocument's .SetDataSource.

And here[^] is an MSDN article about Using the DataSourceConnections Class for Database Logon.

Hope it helps.
