vc6.0 可执行文件生成位置? 编译没错,运行出错 急~~

[anty251]

路过大侠,我在网上下可以运行的例子,我照样写了个，编译没有错，运行时候出错,请问下是不是和那个可执行文件生成的位置有关,例子中可执行文件在工程中生成,我是是在工程的Debug生成,请问下这又是如何设置的?谢谢

属性的link下可以设置输出路径

[anty251]

我改了,问题应该不是错在那里?
vc6.0 一般编译没错,运行有错是什么原因呢?

[cang0lang]

很多，
尤其是涉及到指针的，
很多都是编译不会出错，比如说指针为空、没有实体什么的，编译都不会有错，但运行就会出错

[缘来是梦]

你把错误信息拿出来看看

编译没错,运行出错了

晕 ~~网上下的例子是可以运行的,我把我工程中的.cpp文件换过去,竟然也能运行,那说明,不是我代码的问题了?
那到底会是什么错误呢?
