【求助】创建新线程后编译出错

是一个数据传输程序，开始用的是单线程，但是当程序运行后用户就不能对界面的按钮操作了，当然数据还是继续传输的：（

于是就想弄个新线程专门用来传输数据（应该可行吧？）

于是在NewDlg.h中新加一线程函数 static UINT ReceiveThread(void *param);

在NewDlg.app需要调用线程的函数里面添加了 AfxBeginThread(ReceiveThread,this);

然后线程ReceiveThread是这么定义的：

#include <iostream>
#include <fstream>
using std::ofstream;
using std::ifstream;
using std::ios;
using std::endl;

void CNewDlg::OnButtonSenddata()
{
// TODO: Add your control notification handler code here
if(m_connect==0)
{

ShowInfo("设备未连接",2); ////////////////信息框输出
return;
}

AfxBeginThread(ReceiveThread,this);

}

int decimal, sign;
UINT CNewDlg::ReceiveThread(void *param)
{
CNewDlg *dlg = (CNewDlg*)param;

if(dlg==NULL)
return -1;

ifstream InFile("test1.txt",ios::in);
ofstream OutFile("备份说明文档1.txt",ios::out);

if (!InFile)

{

MessageBox("出错!请检查您的源数据文件是否存在!","警告",MB_ICONQUESTION);
return -1; }
if( !OutFile )
{
MessageBox("创建文件出错!");
return -1;
}

double FileData[1];
CString str_double;

int datasum=0; //数据个数
double atime=0; //传输所需平均时间

while(InFile >> FileData[0])
{
LARGE_INTEGER litmp; //采用QueryPerformanceFrequency和QueryPerformanceCounter延迟20ms
LONGLONG QPart1,QPart2;

double dfMinus,dfFreq,dfTim;

QueryPerformanceFrequency(&litmp);
dfFreq = (double)litmp.QuadPart;

QueryPerformanceCounter(&litmp);
QPart1 = litmp.QuadPart;

for(;;)
{
QueryPerformanceCounter(&litmp);
QPart2 = litmp.QuadPart;

dfMinus = (double)(QPart2-QPart1);
dfTim = dfMinus/dfFreq;

if(dfTim >= 0.02)
break;
}
str_double = _fcvt (FileData[0], 8, &decimal, &sign);

m_EditSendData=str_double;

VCI_CAN_OBJ frameinfo;

char szFrameID[9];
unsigned char FrameID[4]={0,0,0,0};
memset(szFrameID,'0',9);
char szData[9];
BYTE datalen=8;

UpdateData(true);

memcpy(&szFrameID[8-m_EditSendFrmID.GetLength()],(LPCTSTR)m_EditSendFrmID,m_EditSendFrmID.GetLength());
strtodata((unsigned char*)szFrameID,FrameID,4,0);

strcpy(szData,(LPCTSTR)m_EditSendData);

UpdateData(false);
frameinfo.DataLen=datalen;
memcpy(&frameinfo.Data,m_EditSendData,strlen(m_EditSendData));

int b=strlen(m_EditSendData);

for(int i=strlen(m_EditSendData);i<8;i++)
{
frameinfo.Data[i]='\0';
}

frameinfo.RemoteFlag=m_ComboSendFrmFmt;

frameinfo.ExternFlag=m_ComboSendFrmType;
frameinfo.ID=((DWORD)FrameID[0]<<24)+((DWORD)FrameID[1]<<16)+((DWORD)FrameID[2]<<8)+
((DWORD)FrameID[3]);

frameinfo.SendType=0;

QueryPerformanceCounter(&litmp);
QPart1 = litmp.QuadPart;

if(VCI_Transmit(m_devtype,m_devind,m_cannum0,&frameinfo,1)==1) //发送数据
{

ShowInfo("通道0发送成功",0);

}

if(VCI_Receive(m_devtype,m_devind,m_cannum1,&frameinfo,1,100)==1) //接受数据
{
QueryPerformanceCounter(&litmp);
QPart2 = litmp.QuadPart;

dfMinus = (double)(QPart2-QPart1);
dfTim = dfMinus/dfFreq;
atime+=dfTim;
datasum++;

CString str,tmpstr,strdfTim;
double Receive_Double[1],Double_Data;
char *restr_double=(char *)Receive_Double;
CString restr_double2;

for(int i=0;i<8;i++)
{
restr_double[i]=frameinfo.Data[i]; //BYTE__>char
}
restr_double2=restr_double; //char__>CString
Receive_Double[0]=atof((LPCTSTR)restr_double2); //CString__>double

Double_Data=Receive_Double[0]/pow(10,8-decimal);

if(sign==1 &&decimal < 0)
{
Double_Data = -Receive_Double[0]/pow(10,8);
}
if(sign==1 && decimal >= 0)
{
Double_Data = -Receive_Double[0]/pow(10,8-decimal);
}
if(sign==0 &&decimal < 0)
{
Double_Data = Receive_Double[0]/pow(10,8);
}

m_ListInfo.InsertString(m_ListInfo.GetCount(),str);
m_ListInfo.SetCurSel(m_ListInfo.GetCount()-1);
OutFile << p <<endl;

}
else
{
ShowInfo("发送失败",2);
return -1;
}
}

m_ListInfo.InsertString(m_ListInfo.GetCount(),str);
m_ListInfo.SetCurSel(m_ListInfo.GetCount()-1);
OutFile << p <<endl;

return 0;
}

程序编译时出现了如下的错误：
