使用visual basic的组合框项目突出显示事件
问题描述：
大家好！我希望有人能帮助我解决这个问题。我只使用Visual Basic Express Edition。我想知道当组合框下拉项突出显示时如何编码事件。
例如：从下拉列表中，项目是红色，橙色和蓝色。当光标悬停在项目orange上方时，我希望label1.text等于突出显示项目的值。
非常感谢大家！
Hi Everyone! I wish someone can help me shed some light on this problem. I am using Visual Basic Express Edition only. I want to know how to code an event when combobox dropdown item is highlight.
Example: from the dropdown list, the items are red, orange and blue. When the cursor is hovered above the item "orange", I want label1.text to equal the value of the highlighted item.
Thanks much everyone!

您必须编写自己的ComboBox版本才能执行此操作。将鼠标悬停在列表中的项目上没有此类事件。
You'd have to write you own version of a ComboBox to do this. There is no such event for the mouse hovering over an item in the list.
