这个代码怎么运行，为什么QAxWidget不能用

[hb_hyl]

#include <QtGui>
#include <QAxObject>
#include <QAxWidget>

int main(int argc, char **argv)
{
QApplication a(argc, argv);

QAxWidget word("Word.Application");
word.setProperty("Visible", true);
QAxObject * documents = word.querySubObject("Documents");
documents->dynamicCall("Add (void)");
QAxObject * document = word.querySubObject("ActiveDocument");

document->dynamicCall("SaveAs (const QString&)", QString("e:/test/docbyqt.doc"));
document->dynamicCall("Close (boolean)", false);
word.dynamicCall("Quit (void)");
return 0;
}

构建项目aa 时发生错误 (目标: 桌面)
当执行构建步骤 'Make'时


为什么

是不是包含的头文件路径错误了类似下面的
#include <QtGui/QApplication>
#include <ActiveQt/QAxWidget>

Qt是有名字空间的吧
好像没见你引用啊

com组件你把它看成是一个EXE就是了，要操作数据库的话，要么每个用户机子上都有你要用的数据库，这不可能；要么就只能你在服务器上部署一个数据库了。

这么做又有两种做法，一是com组件在用户机上直接通过远程访问数据库，数据库访问接口暴露在互联网上，相当容易受攻击；二是采用COM的远程调用的方式，由服务器端来执行数据库操作。
