IE BHO在工具栏按钮单击上显示一个消息框. [英] IE BHO display a messagebox on toolbar button click.

问题描述

我正在使用C ++(ATL)为IE开发BHO.通过注册表，我在IE中添加了一个工具栏按钮，该按钮调用了我的COM dll.但是，如何使它在单击按钮时显示消息框(而不是加载/卸载插件).

I am developing BHO for IE with C++ (ATL). Via registry I have added a toolbar button into IE that calls COM dll of mine. However, how could I make it display a message box on button click (not load/unload of addin).

推荐答案

您需要向按钮添加消息处理程序:

You need to add a message handler to your button:

<br />
  ON_BN_CLICKED( BUTTON_ID, OnBtnClick )<br />

而且，当然还有一个功能:

And, of course a function for that:

<br />
afx_msg void ClassName::OnBtnClick()<br />
{<br />
MessageBox( "Some test text" );<br />
}<br />

我只是在IE的BHO中尝试过...效果很好！

I just tried it in my BHO for IE... works fine!

将此2个块添加到您的类源文件中:

Add this 2 blocks to your class source file:

<br />
BEGIN_MESSAGE_MAP(YourClassName, YourBaseClass)<br />
ON_BN_CLICKED( BUTTON_ID, OnBtnClick )<br />
END_MESSAGE_MAP()<br />

<br />
afx_msg void YourClassName::OnBtnClick()<br />
{<br />
MessageBox( "Some test text" );<br />
}<br />

将此行添加到您的类头文件中:

Add this line to your class header file:

<br />
afx_msg void OnBtnClick();<br />

就这些...您还需要什么? :)

That''s all... what else do you need? :)
