[ARX程序]：全局变量？

bluesolar

有几个对话框，他们间要相互引用数据
问这些数据在哪里声名才行？
谢谢！

如果是在同一个工程中，在stdafx.h文件中声明变量就可以了

我在CDocData作出了声明，但出错了，
我再试一试你的办法吧！
//CDocData.cpp部分代码：
AsdkDataManager<CDocData> DocVars;
CDocData::CDocData()
{
        m_Scale=2000;
        Begun=false;
        First=true;
        pPolyXL=new AcDbPolyline(1);
}
//StdArx.h部分代码：
extern AsdkDataManager<CDocData> DocVars;
#define WorldInfo DocVars.docData();
//前两个错误的代码：
        WorldInfo.Begun=true;
        WorldInfo.m_Scale=atoi(m_scalePm);
以后凡涉及到WorldInfo.的都出错。
谢谢帮忙！
