如果打开了不同的版本，为什么要获取单词实例? [英] Hw to get word instances if different versions opened?

问题描述

如果运行不同版本的MS Office，如何不获取word/PPT应用程序的运行实例?
如果打开了多个版本的文档，则此代码不会返回所有的错误.
请帮忙.

Hi,
How to get no of running instances of word/PPT applications if different versions of MS office running?
This code does not return all the insatnces if multiple versions documents opened.
Please help.

//for powerpoint instance
ppApp = new Microsoft.Office.Interop.PowerPoint.Application();
//for word instance
                        wordApp = (Microsoft.Office.Interop.Word.Application)System.Runtime.InteropServices.Marshal.GetActiveObject("Word.Application");

推荐答案

每个版本的COM库很可能只能访问相同版本的那些实例.因此，如果您有2个版本的Office，则可能需要分别与它们进行COM互操作.

针对您的评论:

是的，您需要链接到特定互操作版本的单独程序集.也许可以使用一个通用的程序集作为同步点.

Each version of the COM library will most likely have access to only those instances from the same version. So if you have 2 versions of Office, you''ll probably need to COM interop with them separately.

In response to your comment:

Yeah you''ll need separate assemblies that link to specific interop versions. And maybe a common assembly that can then act as the sync-ing point.

经过类似的管理，它将返回所有正在运行的进程:

Managed to somewhat like this and it will return all the running process:

Process[] wordProcs = Process.GetProcessesByName("WINWORD");
if (wordProcs.Length > 0)
{
   foreach (Process wordProc in wordProcs)
    {
      if (wordProc.MainWindowTitle != "")
        {
           //Do something here
        }
    }

}
