Load report failed 急急!!!

[jackyluck]

最近我在vb.net 2005环境下做crystal report ,我不知道为什么会报这有时会出现"Load report failed "错
当运行到红色代码时,这个问题时好时坏
下面是我的代码:

Dim report As New report '厨
Dim R45Data As New R45Data '璸衡amount摸
Dim dataset As New DataSet
Dim sql As String

connectionDB() '连接数据库
sql = strSql.returnR45TdcInSql(businessDate, businessDate)
SqlDataAdapter = New SqlDataAdapter(sql, con)
SqlDataAdapter.Fill(dataset, "R45TDC")
colseDB()

R45Data.setReportDataSet(dataset) '统计dataset数据
R45Data.account() '开始计算
report.SetDataSource(R45Data.saveData()) 'R45Data.saveData()是反回一个计算好后的dataset
report.SetParameterValue("Datadate", busDate2)

Load report failed
加载报表失败！！
仔细上网查查报表的东西吧~~~建议！

也可能返回的数据为空或数据表字段不对应报表中的.

可能是你的报表使用次数没了.

把C:\Program Files\Common Files\Business Objects\2.7\Managed 下所有的文件都COPY到远程服务器网站的BIN目录下，
c.改注册表HKEY_LOCAL_MACHINE\SOFTWARE\Crystal Decisions\10.2\Report Application Server\InProcServer\PrintJobLimit将PrintJobLimit由75改为0

改完后重启一下电脑试试.

还有.看你的代码都觉得有些怪怪的.为什么要用两个dataset,一个不就可以了.

我把c.改注册表HKEY_LOCAL_MACHINE\SOFTWARE\Crystal Decisions\10.2\Report Application Server\InProcServer\PrintJobLimit将PrintJobLimit由75改为0 ，但结果一样，有时报错有时正常

时好时坏就很难讲
建议把模板重新做一下看看
