更改默认Excel [英] Change default Excel

问题描述

您好，



我创建了一个新的Excel应用程序：

 Application xlApp =  new  Application（）; 
工作簿wbs = xlsApp.Workbooks; 
工作簿wb = wbs.Add（ 1 ）; 
 ... 

如果用户手动打开Excel文件，它将在此实例中打开。 br />


如果在执行代码之前打开了Excel文件，那么它就会打开Excel文件。



总之，Excel文件打开：



- 在新实例中如果之前没有

- 在第一个实例中Excel打开



因此我会将Excel xlApp设置为打开Excel文件的默认，特别是如果之前打开了另一个Excel实例。



谢谢你，

Hello,

I created a new Excel application with:

Application xlApp = new Application ();
Workbooks wbs = xlsApp.Workbooks;
Workbook wb = wbs.Add (1);
...

If the user opens "by hand" an Excel file, it will open in this instance.

If an Excel file is opened before the code is executed, then it is in it that will open Excel files.

In summary, Excel files open :

- in a new instance if there was not before
- in the first instance of Excel open

So I would make my Excel xlApp "default" for open Excel file, especially if another instance of Excel is opened before.

thank you,
