Microsoft.Office.Interop.Word“无法激活应用程序”

发布于 2024-10-25 12:49:04 字数 576 浏览 1 评论 0原文

当尝试通过 Office 互操作从我们的应用程序启动 Word 时，一些用户遇到了一个问题：

using Word = Microsoft.Office.Interop.Word;

public void ShowWord()
{
  _word = new Word.ApplicationClass();
  _word.Visible = true;
  _word.Activate();
}

如果 Word 不总是打开，则会抛出 COM 异常，指出“无法激活应用程序”。在调用 _word.Activate() 之前添加 Thread.Sleep(1000) 可以防止这种情况发生，但显然并不理想。

public void ShowWord()
{
  _word = new Word.ApplicationClass();
  _word.Visible = true;
  Thread.Sleep(1000)
  _word.Activate();
}

有没有人以前见过这个并知道是什么原因造成的以及解决这个问题的正确方法是什么？

We are having a problem experienced by a few users when attempting to launch Word from our application via the office interop:

using Word = Microsoft.Office.Interop.Word;

public void ShowWord()
{
  _word = new Word.ApplicationClass();
  _word.Visible = true;
  _word.Activate();
}

If word is not always open a COM exception is thrown stating "Cannot activate application." Adding a Thread.Sleep(1000) before calling _word.Activate() prevents this, but obviously is not ideal.

public void ShowWord()
{
  _word = new Word.ApplicationClass();
  _word.Visible = true;
  Thread.Sleep(1000)
  _word.Activate();
}

Has anyone seen this before and knows what is causing this and what the right way to fix this is?

我们遇到了类似的问题，Word 似乎正在异步等待操作系统显示其窗口。我们解决这个问题的方法是等待 Visible 属性返回 true：

public void ShowWord()
{
  _word = new Word.Application();
  _word.Visible = true;

  System.Diagnostics.Stopwatch sw = System.Diagnostics.Stopwatch.StartNew();
  while (!_word.Visible && sw.ElapsedMilliseconds < 10000)
  { /* Just Wait!! (at most 10s) */}
  _word.Activate();
}

希望这对某人有帮助。

We encountered a similar issue, and it seems that Word is asynchonously waiting for the OS to show its window. The way we resolved this is by waiting until the Visible property returns true:

public void ShowWord()
{
  _word = new Word.Application();
  _word.Visible = true;

  System.Diagnostics.Stopwatch sw = System.Diagnostics.Stopwatch.StartNew();
  while (!_word.Visible && sw.ElapsedMilliseconds < 10000)
  { /* Just Wait!! (at most 10s) */}
  _word.Activate();
}

Hope this helps somebody.
