本文介绍了为什么我得到一个“成员函数不存在”评估VC ++调试器上的表达式时出错?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我有一个静态方法, MyClass :: myMethod()在另一个DLL, MyDll.dll 。在我的代码中,我调用这个方法,它编译并运行正常。

I've got a static method, MyClass::myMethod() on another DLL, MyDll.dll. In my code, I call this method, and it compiles and runs fine.

但是当我尝试 MyClass :: myMethod()在立即窗口(或观察窗口)中,我总是得到:

But when I try MyClass::myMethod() in the immediate window (or the watch window), I always get:

MyClass::myMethod()
CXX0052: Error: member function not present

为什么这样?

更新:我发现当我使用它的工作原理:

Update: I've found out that when I use the context operator it works:

{,,MyDLL}MyClass::myMethod()

我不太确定为什么需要它,所以我要去稍等一下,看看有没有一个很好的解释。

I'm not really sure why it's needed, though, so I'm going to wait a bit to see if someone has a nice explanation.

更新2 :我被要求提供更多信息。不幸的是,我所描述的几乎是我所有的。这是第三方代码。该方法驻留在不同的DLL中,如下所示:

Update 2: I was asked to give more information. Unfortunately, what I described is almost all I have. This is in third-party code. The method, which resides on a different DLL, is declared like this:

class MyClass
{
 public:
 // ...
 _declspec(dllimport) static const char *getDirectory(void);
}

它被这样调用:

MyClass::getDirectory ()

我没有来源它是在VC ++ 9下的调试模式下编译的。

I haven't got the source. It was compiled on Debug mode under VC++9.

推荐答案

嗯,我不知道为什么,但调试器是足够聪明才能知道该类在另一个DLL中,因此您必须通过使用:

Well, I'm not sure why, but the debugger isn't smart enough to know that class is in another DLL, so you have to explictly tell it by using the context operator:

{,,MyDLL}MyClass::myMethod()
