由于机器配置的问题,现在只能用VC6,可是需要调用msvcr80.dll中的一个_time64这个函数,应该怎么调用呢?
HMODULE dllMod=LoadLibrary("msvcr80.dll");
if(dllMod==NULL)
{
MessageBox(0,"Error","Error",0);
exit(0);
} FARPROC tFun=GetProcAddress(dllMod,"_time64");
if(tFun==NULL)
{
MessageBox(0,"Error","Error",0);
exit(0);
}我这样写找不到这个dll,而且会出现一个运行时错误
Runtime Error
R6034An application has made an attempt to load the C runtime library incorrectly
Please contact the application's support team for more information这个是不是要从VC6里面设置些什么东西啊

要么升级vc,要么想其他方法实现
