mfc 开发office 的工具栏 activex 控件时,需要继承那些接口,及步骤?
例如:用atl开发的话,需实现IDTExtensibility2 接口,
mfc 实现该接口时 提示不能实现抽象基类的错误.

望蒋大哥给点明示:

其他知道的大哥大姐们,不吝赐教了

IDTExtensibility2接口是Office插件必须实现的接口。

现在是我实现了IDTExtensibility2,报 无法初始化抽象基类_IDTExtensibility2

Office的接口只有一个，用MFC或者ATL都是调用的同一个接口
MFC实现COM接口的方法可以参考http://msdn.microsoft.com/en-us/library/5hhehwba.aspx

我想用onconnect()
和ondisconnect()方法;

在启动word时在onconnect()事件中
把自定义工具栏添加上,
关闭word时,在ondisconnect()事件中把自定义工具栏卸载掉;


不实现IDTExtensibility2接口,在那里添加这些代码

[蒋晟]

看看编译输出里面抱怨什么函数没有实现

[lvfeng180]

牛人,小弟实在是佩服.
