我希望能够使用vb.net从winform之外复制高亮文本。
例如,如果用户在浏览器或记事本中突出显示文本,则应将其复制到winform中的文本框中。
非常感谢任何帮助!
提前致谢。
好的!感谢this链接,我得到了答案。
我的逻辑是首先用户将突出显示一个值,不限于浏览器,而是任何地方。 然后用户将按下热键,在我的情况下是F8。然后代码将触发复制命令,然后检索剪贴板值并将其分配给文本框文本。 以下是完整的代码和帮助类。

,检查它自上次以来是否发生了变化,如果变化了,则在表单中显示更改,否则将剪贴板重置为旧值。 - FixationEVENT_OBJECT_TEXTSELECTIONCHANGED
,而该代码当然使用的是EVENT_OBJECT_LOCATIONCHANGE
。请注意,你只需要钩取主窗口。文本选择更改通知适用于具有通知文本选择更改的自动化TextPattern的任何子窗口。 - Jimi... && idObject == (Hook.SWEH_ObjectId)Hook.SWEH_CHILDID_SELF
条件,因为它是为了防止子对象通知激活相同的过程而添加的,而现在您希望它们被激活。 - Jimi
