推荐答案

您必须了解工具栏api。阅读概述使用工具栏控件。



您可以使用底层的 CToolBarCtrl 获得更好的访问权限。在该类中，您可以使用GetButton和 SetButtonInfo 函数来操作控件。



最多 easilist solution 。

You must learn about the toolbar api. Read the overview Working with the Toolbar Control.

Finer access you get with the underlying CToolBarCtrl. In that class you have the GetButton and SetButtonInfo functions to manipulate the control.

The most easilist solution.
