BHO中的窗口及控件为什么都没有视觉样式？

Question

如题？这个问题已经困扰我很长时间了，希望有哪位专家能帮忙告诉我如何解决？

我发现好像BHO会加载版本比较老的comctl32.dll库，而IE自身会加载比较新的库。

这些库都在WinSxS文件中的不同文件夹下，不知道有哪些因素可以影响这个库的加载，

什么加manifest文件，什么加一段

#pragma comment(linker,"/manifestdependency:\"type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='x86' publicKeyToken='6595b64144ccf1df' language='*'\"")

我试过了，似乎对BHO的DLL都没有用。

Answer 2

谢谢，

我试了一下，实际上不起作用。

Answer 3

VS的扩展插件也是基于COM的。我生成一个工程，直接在里面写一个MessageBox，它就带有视觉样式。

同样的BHO为什么就不行呢？？？？

Answer 4

每个DLL都可以提供自己的activation context，这个可以用来决定dll加载的是哪个版本的windows common control

Answer 5

那么这个activation context是在DLL生成的时候就固定的还是配置的？

如果是配置如何配置呢？

谢谢

Answer 6

是读的manifest。你可以在DLL中加一个manifest资源来替代默认的激活上下文，这也决定DLL加载的通用控件版本，影响DLL创建的窗口的视觉效果。具体步骤参考Office插件那篇文章。
