提示：
 E:\hulei\test\exam11\exam11.cpp(326) : error C2664: '__thiscall MyAppDocGlobals::MyAppDocGlobals(const class MyAppDocGlobals &)' : cannot convert parameter 1 from 'class AcApDocument *' to 'const class MyAppDocGlobals &'         Reason: cannot convert from 'class AcApDocument *' to 'const class MyAppDocGlobals'         No constructor could take the source type, or constructor overload resolution was ambiguous

hulei_accp 发表于 2005-9-9 17:52:00

可能是
gpMyAppDocGlobals=new MyAppDocGlobals(curDoc());
参数类型不正确，不知道怎么该？

hulei_accp 发表于 2005-9-9 17:52:00

MyAppDocGlobals *gpMyAppDocGlobals;
这是一个全局变量。

hulei_accp 发表于 2005-9-9 17:54:00

MyAppDocGlobals是我定义的一个类，
curDoc()是一个函数，返回AcApDocument类型。

MyAppDocGlobals是我定义的一个类，
curDoc()是一个函数，返回AcApDocument * 类型。
