书上说把这段代码直接加在ch1view.cpp
#include"afxmt.h"
int m_count;
int m_data[5];
CCriticalSection critical;
//////////////////////////////////////////////////////////////////////////
class ch1View : public CView
{ UINT MyFunction1(LPVOID param)

{
critical.Lock();
for (int i=0;i<5;i++)
{
m_count++;
::Sleep(200);
m_data[i]=m_count;
}
critical.Unlock();
CString str;
str.Format("%d-%d-%d-%-%d",m_data[0],m_data[1],m_data[2],m_data[3],m_data[4]);
MessageBox((HWND) param,str,"1",MB_OK);
return 0;
}
UINT MyFunction2(LPVOID param)
{
for (int i=0;i<5;i++)
{
m_count++;
::Sleep(150);
m_data[i]=m_count;
}
CString str;
str.Format("%d-%d-%d-%d-%d",m_data[0],m_data[1],m_data[2],m_data[3],m_data[4]);
MessageBox((HWND)param,str,"2",MB_OK);
return 0;
}
是这样直接在view中添加吗？
//////////////////////////////////////////////////////////////////////////
下面是两个菜单处理程序
void CCh7_2View::OnCom()
{
// TODO: Add your command handler code here
m_count=0;
HWND hWnd=GetSafeHwnd();
AfxBeginThread(MyFunction2,hWnd);
AfxBeginThread(MyFunction2,hWnd);
}

void CCh7_2View::OnCri()
{
// TODO: Add your command handler code here
m_count=0;
HWND hWnd=GetSafeHwnd();
AfxBeginThread(MyFunction1,hWnd);
AfxBeginThread(MyFunction1,hWnd);
}
结果出现了很多错误：

请大侠们指教，
先谢谢！

但是还是有错误，运行的时候出现这个错误：

怎么发送图片呢？我这里编译连接都能通过，就是运行的时候出现exception的现象！，谢谢您的帮助！
