[英]How to add handlers to Excel Calculate Events with ExcelDNA
I would like to be able to listen to the BeginCalculate and EndCalculate events for all sheets in Excel from my ExcelDNA addin, and execute some intialization code. 我希望能够从我的ExcelDNA插件监听Excel中所有工作表的BeginCalculate和EndCalculate事件,并执行一些初始化代码。 Is there a way to do this?
有没有办法做到这一点?
There was some discussion on the Excel-DNA Google group here: https://groups.google.com/group/exceldna/browse_frm/thread/58da470968d6658b This shows how to handle the C API ON.RECALC event, which fires after a recalculation. 关于Excel-DNA Google小组的讨论如下: https ://groups.google.com/group/exceldna/browse_frm/thread/58da470968d6658b这显示了如何处理C API ON.RECALC事件,该事件在重新计算后触发。
You can get also hold of the Excel Application COM object with a call to ExcelDnaUtil.Application
, and then register your event handlers for the Application events. 您还可以通过调用
ExcelDnaUtil.Application
获得Excel Application COM对象,然后为Application事件注册事件处理程序。 The Application events are documented here: http://msdn.microsoft.com/en-us/library/office/jj734018.aspx and you might be interested in AfterCalculate
. 此处记录了应用程序事件: http : //msdn.microsoft.com/zh-cn/library/office/jj734018.aspx ,您可能对
AfterCalculate
感兴趣。
I don't know of any Excel events that fire before recalculation. 我不知道在重新计算之前会触发任何Excel事件。
