WM_COPYDATA

看不懂，能否讲详细点

[xiaoshi0]

用这个消息WM_COPYDATA

或者CreateFileMapping也可以，这是最正规的

一个简单例子

class a:pulick dialog
{
public:
void GetVar(int &a,int &b)
{
a = m_na;
b = m_nb;
return;
}
private :
int m_na;
int m_nb;

};

class b:pulic dialog
{
public:
GetADlgVar()
{
a *p = new a;
int x,y;
p->GetVar(x,y);

}

};

[tjandy]

class a:pulick dialog
{
public:
void GetVar(int &a,int &b)
{
a = m_na;
b = m_nb;
return;
}
private :
int m_na;
int m_nb;

};

class b:pulic dialog
{
public:
GetADlgVar()
{
a *p = new a;
int x,y;
p->GetVar(x,y);
delete p;

}

};
