标题一文件打开窗口：

void MyThridWin::OnBnClickedButton1()
{
// TODO: Add your control notification handler code here
TCHAR szFilter[] = TEXT("文本文件(*.txt)|*.txt|所有文件(*.*)|*.*||");
CFileDialog fileDlg(TRUE,TEXT("txt"),NULL,0,szFilter,this);
CString strFilePath;
if (IDOK == fileDlg.DoModal())
{
strFilePath = fileDlg.GetPathName();
SetDlgItemText(IDC_EDIT_OPEN,strFilePath);
}
}

标题二文件保存窗口：

void MyThridWin::OnBnClickedButton2()
{
// TODO: Add your control notification handler code here
TCHAR szFilter[] = TEXT("文本文件(*.txt)|*.txt|所有文件(*.*)|*.*||");
CFileDialog fileDlg(FALSE,TEXT("doc"),TEXT("my"),OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,szFilter,this);
CString strFilePath;
if (IDOK == fileDlg.DoModal())
{
strFilePath = fileDlg.GetPathName();
SetDlgItemText(IDC_EDIT2,strFilePath);
}
}

标题三创建文件：

CStdioFile myFile;
CFileException fileException;

if(myFile.Open("D:\\info.txt",CFile::modeCreate|CFile::typeText|CFile::modeReadWrite|CFile::modeNoTruncate,&fileException))
//if(myFile.Open("D:\\info.txt",CFile::modeCreate|CFile::typeText|CFile::modeReadWrite,&fileException))
{
myFile.SeekToBegin();
CString str;

myFile.ReadString(str);
CString m_all = str;
while(myFile.ReadString(str)!=FALSE)
{
m_all += TEXT("\r\n") + str;
}
UpdateData(FALSE);
AfxMessageBox(m_all);
myFile.Close();
}else{
AfxMessageBox(_T("ERROR"));
}

标题四保存文件：

void MyThridWin::OnBnClickedButton1()
{
// TODO: Add your control notification handler code here
TCHAR szFilter[] = TEXT("文本文件(*.txt)|*.txt|所有文件(*.*)|*.*||");
CFileDialog fileDlg(TRUE,TEXT("txt"),NULL,0,szFilter,this);
CString strFilePath;
if (IDOK == fileDlg.DoModal())
{
strFilePath = fileDlg.GetPathName();
SetDlgItemText(IDC_EDIT_OPEN,strFilePath);
}

CStdioFile myFile;
CFileException fileException;

if(myFile.Open(strFilePath,CFile::modeCreate|CFile::typeText|CFile::modeReadWrite|CFile::modeNoTruncate,&fileException))
//if(myFile.Open("D:\\info.txt",CFile::modeCreate|CFile::typeText|CFile::modeReadWrite,&fileException))
{
myFile.SeekToBegin();
CString str;

myFile.ReadString(str);
CString m_all = TEXT("hello world") + str;
while(myFile.ReadString(str)!=FALSE)
{
m_all += TEXT("\r\n") + str;
}
UpdateData(FALSE);
AfxMessageBox(m_all);
myFile.Close();
}else{
AfxMessageBox(_T("ERROR"));
}
}

CStdioFile myFile;
CFileException fileException;

if(myFile.Open("D:\\info.txt",CFile::modeCreate|CFile::typeText|CFile::modeReadWrite|CFile::modeNoTruncate,&fileException))
//if(myFile.Open("D:\\info.txt",CFile::modeCreate|CFile::typeText|CFile::modeReadWrite,&fileException))
{
myFile.SeekToBegin();
CString str;

myFile.ReadString(str);
CString m_all = str;
while(myFile.ReadString(str)!=FALSE)
{
m_all += TEXT("\r\n") + str;
}
UpdateData(FALSE);
AfxMessageBox(m_all);
