C ++ / CLI - 基于XML的活动报告 [英] C++/CLI - XML based active reports

问题描述

这是我之前的一个查询的继续（ C / CLI中的活动报表< a>）。我从C ++ / CLI应用程序访问基于xml的活动报告。是否有任何方式可以与来自C ++ / CLI的活动报告进行数据通信，例如，我想打印在C ++ / CLI应用程序中的受管数据在应用程序访问的XML报告的详细信息部分。我不想使用任何c＃代码。可以做吗？谢谢。

This is in continuation to one of my previous queries(active reports in C /CLI). I am accessing an xml-based active report from a C++/CLI application. Is there any way by which I can have a data communication with the active report from C++/CLI, for example, I want to print the managed data present in the C++/CLI application on the details section of the XML report which the application accesses. I don't want to use any c# code. Can it be done? Thanks.

推荐答案

当然，ActiveReports可以做到。由于C ++ / CLI生成标准的.NET对象，您可以在C ++ / CLI中创建对象，ActiveReports将绑定到它们。创建要绑定到的对象的IEnumerable集合（集合中的每个对象都像数据库行）。

Sure, ActiveReports can do it. Since C++/CLI produces standard .NET objects you can create objects in C++/CLI and ActiveReports will bind to them. Create an IEnumerable collection of objects that you want to bind to (each object in the collection is like a database "row").

请参阅将报表绑定到数据源。展开标题下的代码部分以使用IEnumerable数据源，你会看到如何在C＃中做。你将在C ++ / CLI中做同样的事情，你只需要将语法从C＃更改为C ++ / CLI。显然，你知道C ++ / CLI语法，所以你可以做这一部分，但我认为这回答了你的问题关于如何这样做与ActiveReports。

Take a look at the examples at Binding Reports to a Data Source. Expand the code sections under the heading To use the IEnumerable data source and you'll see how to do it in C#. You would do precisely the same thing in C++/CLI, you'll just change the syntax from C# to C++/CLI. Clearly, you know C++/CLI syntax so you can do that part, but I think this answers your question regarding how to do this with ActiveReports.

基于更新在问题中提出的问题：

您应该能够处理ActiveReports的事件，例如 FetchData事件使用类似以下代码：

You should be able to handle an ActiveReports' event such as the FetchData event using something like the following code:

void MyFetchDataHandler(Object^ sender, FetchEventArgs^ eArgs) 
{
 //put handling code here...
}

myReport->FetchData += ref new FetchEventHandler(this, &MyClass::MyFetchDataHandler)

我没有编译这个（我没有AR handy），但它应该是接近。请参阅 Microsoft的C ++ / CLI事件语法参考文档。

I didn't compile this (I don't have AR handy), but it should be close. Please see Microsoft's reference documentation on C++/CLI event syntax here.
