Vb.Net-如何清除水晶报表参数 [英] Vb.Net - How do you clear crystal reports parameters

问题描述

我有一个使用Crystal Reports的应用程序.如果我运行报告，例如报告A，效果很好.然后我尝试运行其他报告，例如报告B具有比报告A更多的参数，我收到一条错误消息参数不正确".然后，我尝试运行报表A并得到相同的错误消息.要运行其他报告，我必须先退出应用程序，然后再返回.

问题是，如何清除以前的水晶报表以运行另一个?
我应该使用哪种语法，例如Close.

有任何想法吗?

Hi,

I have an application that uses Crystal Reports. If I run a report e.g. Report A, works fine. Then I try running a different report e.g. Report B that has more parameters than Report A, I get an error message "The parameter is incorrect". I then try running Report A and get the same error message. To run a different report I have to come out of the application and then go back in.

The question is, How do I clear the previous crystal report to run another?

What syntax should I use e.g Close.

Any ideas?

感谢您的所有解决方案.

报告完成后，我错过了一小段代码.

parameterfields.Clear()

添加此行将清除参数.

Thanks for all your solutions.

I was missing one wee bit of code once the report was finished.

parameterfields.Clear()

Adding this line cleared the parameters.
