E0298 inherited member is not allowed MfcMenu
时间: 2023-11-06 11:52:34 浏览: 79
这个错误 E0298 是由于在 MFC(Microsoft Foundation Classes)中,不能继承 MfcMenu 成员导致的。MFC 是一个用于开发 Windows 应用程序的 C++ 框架,它提供了一些预定义的类和函数来简化 Windows 程序的开发。
MfcMenu 是 MFC 中的一个类,用于创建和管理菜单。根据错误消息,你可能在尝试继承 MfcMenu 的成员,但这是不允许的。
要解决这个问题,你可以考虑以下几个方案:
1. 检查你的代码,确保没有尝试继承 MfcMenu 的成员。如果有,请移除或修改相关代码。
2. 确认你的类的基类是否正确,是否应该继承自 CMenu 或其他合适的类而不是 MfcMenu。
3. 如果你确实需要扩展 MfcMenu 的功能,可以考虑使用组合而不是继承。创建一个新的类,在其中包含一个 MfcMenu 对象,并实现你需要的额外功能。
希望这些解决方案能够帮助你解决这个问题!如果你有更多的问题,请随时提问。

This type is final, so it cannot be inherited from
As an AI language model, I can confirm that this statement is correct. A final class in object-oriented programming is a class that cannot be extended or inherited from. Once a class is marked as final, it cannot be subclassed or inherited by any other class. This is often used to prevent further modification of a class or to ensure that certain methods or properties cannot be overridden.
PickUpItem.transform' hides inherited member 'Component.transform'. Use the new keyword if hiding was intended.
This is a warning message in C# that appears when a class is defining a member with the same name as a member in its base class. In this case, the class PickUpItem is defining a member called "transform", which is already defined in its base class Component.
To resolve this warning, you can either rename the member in PickUpItem to something else, or use the "new" keyword to explicitly indicate that you are intentionally hiding the inherited member.
For example:
```
public new Transform transform;
```
This will suppress the warning and allow you to define a new member with the same name as the base class member. However, be aware that using the "new" keyword can potentially cause confusion and should be used sparingly.
