答

我认为上面的代码有两个问题

1.检查你的cryRpt对象

2.检查.rpt文件的数据集名称和配置

I think above code having two problem
1. check your cryRpt object
2. check dataset name and configuration of .rpt file

I * n选择查询仅提及你想要的那些参数

egSELECT EMPFIRSTNAME，EMPLASTNAME FROM Employee而不是SELECT * FROM .....

休息你的代码是正确的..我在猜...所以试试这个

I*n Select query mention only those parameter that which you want
e.g.SELECT EMPFIRSTNAME,EMPLASTNAME FROM Employee instead of SELECT * FROM.....
Rest your code is correct ..i am guessing...So try this
