如何识别浏览器栏（Internet Explorer）是否隐藏？

Question

I can make an Explorer bar show/hide using IWebBrowser2::ShowBrowserBar Method. I want to use a single button to toggle between Show/Hide. There is a parameter for ShowBrowserBar to set for Show/Hide. How will I get the status of the explore bar now?

Answer 1

Couldn't you just check the value of pvaShow to get the status of the bar? IWebBrowser2::ShowBrowserBar Method

pvaShow [in] A pointer to a VARIANT of type VT_BOOL that specifies whether the browser bar should be shown or hidden. If this is nonzero, the browser bar is shown. If this is zero, the browser bar is hidden.
