我自己解决了这个问题!!!我很高兴……哈哈。我没有尝试自动热键,但我找到的解决方案是一个很好的解决方案,或者至少我认为它是。这里提供了一个很好的解释...... http://msdn.microsoft.com/en-us/magazine/cc163288.aspx
无论如何,解决方案是 vb.net 有一个“UI 自动化”库/参考,您可以将其添加到您的项目中。我在网上看到它提到过几次,但不知道如何导入它(对不起,我是 vb.net/coding newby)。无论如何,您将“UI 自动化”引用添加到您的项目,然后将其导入。然后,您可以使用该库来查找屏幕上的所有控件。这包括工具条中的所有按钮。
我在下面添加了一个代码示例来演示我是如何解决它的。我敢肯定它在某种程度上很复杂,可能会做得更好,但它确实有效。让我知道您对代码/解决方案的看法。
为了运行代码,您需要知道按钮的索引和工具条的索引。如果您进入调试模式,您可以手动增加索引并检查 controlName 直到出现正确的按钮。在下面的示例中,我必须找到父元素(窗口),然后是子元素(工具条),然后是子元素(工具条下的所有按钮)。
