这篇博客探讨了如何编程方式从MS Word中删除加载项。即使已删除注册表条目，按钮仍然保留在加载项选项卡中。文章通过使用COM接口和CoCreateInstance方法，展示了遍历命令栏和控件，查找并删除指定标题的按钮的代码示例。

I need to programmatically remove an add-in from MS Word. I have deleted the registry entry corresponding to it, and the button is now disabled (nothing happens when you click it) and the add-in no longer appears on the list of COM Add-ins.

The button, however, remains in the Add-ins ribbon menu. How can I remove that programmatically?

CoInitialize(NULL);
CLSID clsid;
IDispatch *pWApp, *pCommandBars, *pCommandBar, *pCommandBarControls, *pCommandBarControl;

if (SUCCEEDED(hr))
{

        hr = CoCreateInstance(clsid, NULL, CLSCTX_LOCAL_SERVER, IID_IDispatch, (void **)&pWApp);
