其实对于第一种情况,如果你在基类构造函数或析构函数中直接调用纯虚函数,编译器应该能捕捉到这个错误;间接的调用虽然编译器无法检测到,但是由于Scott同学在<Effective C++>中的大力宣传:Item 9: Never call virtual functions during construction or destruction,这种情况发生的概率应该比较小,况且即使发生了,排起错来...
一些短小的验证代码:Pure_Virtual_Function_Called考虑到的.rar
Note that calling a specific explicitly qualified function is not a virtual call even if the function is virtual. 注意:调用一个特定的限定函数不是虚调用,即使这个函数是虚函数。 See also factory functions for how to achieve the effect of a call to a derived class function without risking undefine...
virtual void foo()=0; // =0标志一个虚函数为纯虚函数 }; 纯虚函数不能被实例化,如下面: Father* a = new Father(); //error, 编译错误是:because the following virtual functions are abstract: 一个函数声明为纯虚后,纯虚函数的意思是:我是一个抽象类!不要把我实例化!纯虚函数用来规范派生类的...
程序:C\WINNT\explorer.exe运行时出错!R6025-pure 纯虚函数调用失败!程序出了 R6025 - pure virtual function call 错误，主要原因是在基类的构造函数中调用了纯虚函数,如果构造函数直接调用纯虚函数，链接时会出错。只有通过一个其它成员函数转调一下。explorer.exe 桌面,2000系统的系统文件,非病毒,...
十有八九是病毒的问题，因为资源管理器不需要加参数就可以运行。建议你安装一个防病毒软件好好查查。explorer
Runtime Error: R6025 - pure virtual function call MajesticTwelve New Here , Dec 11, 2013 Copy link to clipboard When I watch the fullscreen video on this site and it ends, instead of continuing to the next part (you can see there are 3 parts of this video), I get this e...
No object has been instantiated to handle the pure virtual function call. This error is caused by calling a virtual function in an abstract base class through a pointer which is created by a cast to the type of the derived class, but is actually a pointer to the base class. This can oc...

如果你安装了迅雷下载软件，请你在你的IE浏览器里的管理加载项中将迅雷下载支持禁用，问题就会得到解决。我就是用这样的方法解决的。IE
