提问by SpinaloS
When trying to print my Crystal Reports RPT(MainReport) in my CrystalReportViewer1, I don't know how to set the parameter for the Subreport (report1).
尝试在我的 CrystalReportViewer1 中打印我的 Crystal Reports RPT(MainReport) 时，我不知道如何设置子报表 (report1) 的参数。
I've tried this:
我试过这个：
Report1.DataDefinition.ParameterFields("@code_machine").CurrentValues.AddValue(3)
But it doesn't work, it show me the input box of CrystalReports.
但它不起作用，它显示了CrystalReports的输入框。
I also tried :
我也试过：
Report1.SetParameterValues("@code_machine", 3)
What am I doing wrong?
我究竟做错了什么？
