新手请教 error C2065: 'p_B' : undeclared identifier

[new_one_one]

本人新手，有一问题请教：

一VC/MFC对话框程序，IDD_MFCDATA_DIALOG是主对话框，B是一张数据表的MFC ODBC类，IDD_DIALOG_ADD是添加的一个对话框
p_B为B的实例。IDD_DIALOG_ADD是从IDD_MFCDATA_DIALOG点出的模态对话框。
现在 IDD_MFCDATA_DIALOG 上对数据表类 p_B 调用操作没问题，但是在 CIDD_DIALOG_ADD 上调用操作数据表类 p_B 则程序报错，提示错误
1 error C2065: 'p_B' : undeclared identifier


请高手指教

有人说
添加
#include "Rsource.h"
到
stdafx.h
文件中



我添加了，可是还是不行

你实例化的时候P_B对象设置为全局的

[zhaichengshenhua]

p_SHPMSPMSTUFF,这个玩意没有定义（编译器不知道你定义在那里）。
“->IsOpen”的左边必须指向类/结构/联合/泛型类型
下面同样错误
