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()
