winapi - IPropertyStory 在不提交的情况下执行 SetValue

Question

我正在关注此博客以编写相同的代码来更改System.AppUserModel.ID窗口：The Old New Thing :: 如何防止用户将我的程序固定到任务栏？

他在做：

hr = pps->SetValue(pkey, var);
PropVariantClear(&var);

他不做pps->Commit()，我很困惑，因为我已经写了代码，我做了SetValue，我做了，Commit但我的改变不会。

他怎么不做Commit？他弄错了吗？还是他是您不需要的特殊情况Commit？

谢谢

The issue was, the var was set to a propvariant which was not properly initailized. My InitFromString function was messing up it would forget to set the var.vt. I dont know why a succesful hr was being returned though.
