然后就报错
1>qux.obj : error LNK2019: 无法解析的外部符号 "public: __thiscall CquxDlg::CquxDlg(class CWnd *)" (??0CquxDlg@@QAE@PAVCWnd@@@Z)，该符号在函数 "public: virtual int __thiscall CquxApp::InitInstance(void)" (?InitInstance@CquxApp@@UAEHXZ) 中被引用 1>D:\My Documents\Visual Studio 2008\Projects\qux\Debug\qux.exe : fatal error LNK1120: 1 个无法解析的外部命令
这怎么改
