推荐答案

您需要在运行时设置参数字段的值.看这些

使用具有.NET的Crystal Reports对数据库登录错误进行故障排除 [ ^ ]

You need to set values for parameter fields at run time. Look at these

Understanding the Login Failed Error in Crystal Reports[^]

Troubleshooting Database Login Errors using Crystal Reports with .NET[^]

所有错误的方向.

我会告诉您，错误无法由任何人解决.由于使用嫁接报告时会出现此错误.这就是为什么水晶报告记录的限制比嫁接的显示更多的原因.
如果删除此错误消息，则从.rpt文件中删除移植.
您不会收到此错误.

All of the gives wrong direction.

i will tell you true that error is not solve by any one. because of this error comes when report using graft. That''s why that is some limitation of crystal report record is more then the graft display.

If you remove this error massage then remove the graft from the .rpt file.
You do''t get this error.

这不是错误.您的报告可以在此之后运行.在Crystal Report首次登录实例中，将其设置为空白.这样就会显示该消息.

Its not a error. Your report can run after that. In crystal Report firsttime login instance set blank. so it shows that message.
