qaxobject requested control excel could not be instantiated

报错问题：
CoCreateInstance failure (尚未调用 CoInitialize。)
QAxBase::setControl: requested control Excel.Application could not be instantiated
解决方法：
#include “Windows.h”
并且在 excel = new QAxObject(“Excel.Application”);前添加CoInitializeEx(NULL, COINIT_MULTITHREADED);
