为什么m_x已在ScaleDlg.h中定义过，而在ScaleDlg.cpp却不认可？
ScaleDlg.h文件内容：#if !defined(AFX_SCALEDLG_H__883BC861_1336_11D7_A714_885276570047__INCLUDED_)
#define AFX_SCALEDLG_H__883BC861_1336_11D7_A714_885276570047__INCLUDED_

}
void DisplayComboBox()
{
m_x.InsertString(-1,"good");
}
编译出现：
d:\LX\scale\ScaleDlg.cpp(55) : error C2065: 'm_x' : undeclared identifier
d:\LX\scale\ScaleDlg.cpp(55) : error C2228: left of '.InsertString' must have class/struct/union type
这是为什么？为什么m_x已经在ScaleDlg.h文件中定义过，而在ScaleDlg.cpp的
void DisplayComboBox()
{
m_x.InsertString(-1,"good");
}
中，却不认可？
请各位高手帮助一下，谢谢！
e_mail:msd0819@mail.dlptt.ln.cn 你的程序中
void DisplayComboBox()
{
m_x.InsertString(-1,"good");
}
应为
void CScaleDlg:isplayComboBox()
{
m_x.InsertString(-1,"good");
}
就行了。
