关于线程的比较菜的问题？？？

[coacoo]

有一个线程UINT _ListenThread(LPVOID lparam)

当我用::AfxBeginThread(_ListenThread,this); 语句时报以下的错误
'_ListenThread' : undeclared identifier
'_ListenThread' : redefinition; different type modifiers

是怎么回事？？盼回复。

给你参考一下：

void CMultiThreadDlg::OnBnClickedButton1()
{
m_button.EnableWindow(FALSE);
i=1;
m_static.SetWindowText("已经花了0秒");
m_progress.SetRange32(0,500000);
AfxBeginThread(ShowTimeThread,GetSafeHwnd(),THREAD_PRIORITY_NORMAL);
AfxBeginThread(SetPosThread,GetSafeHwnd(),THREAD_PRIORITY_NORMAL);
// m_button.EnableWindow(TRUE);
}

UINT ShowTimeThread(LPVOID param)
{
::SetTimer((HWND)param,1,1000,NULL);
return 0;
}

UINT SetPosThread(LPVOID param)
{
int sum=0;
HWND hwnd,btn;
hwnd=::GetDlgItem((HWND)param,IDC_PROGRESS1);
btn=::GetDlgItem((HWND)param,IDC_BUTTON1);
for(int i=1;i<=500000;i++)
{
sum+=i;
SendMessage(hwnd,PBM_SETPOS,i,0);
}
::KillTimer((HWND)param,1);
// SendMessage(btn,WM_ENABLE,TRUE,0);
::EnableWindow(btn,TRUE);
return 0;
}

UINT _ListenThread(LPVOID lparam)应该放在AfxBeginThread(_ListenThread,this)前面

[huanyun]

没有函数声明
可能情况 没有include 包含UINT _ListenThread(LPVOID lparam)的头文件
UINT _ListenThread(LPVOID lparam)没放在AfxBeginThread(_ListenThread,this)前面
