我有一个 Microsoft Word 插件,可以在文本中找到相似的词(但是当我单击按钮时!)
我的问题是:当用户输入单词时如何调用函数?
换句话说,当用户键入以获取当前单词并对其进行处理并获取相似的单词时,我想要一个像“TextChange”或“Keypress”这样的事件。
像这样的东西:
private void TextChangeEventOfCurrentActiveDocument(object sender, System.EventArgs e)
{
...
}
我可以获得用户输入的新单词的任何其他想法?
谢谢。
最佳答案
终于在很长一段时间后,我使用 Windows 钩子(Hook)创建了这个加载项。
(特别感谢@Reg 编辑)
这是我编写的整个代码,这对我来说很好用。 (删除了一些可选的代码部分。)
