通过MFC将数据保存到TXT中

添加保存Button，头文件中#include

在函数中添加如下代码。

void CMyTestDlg::OnBnClickedButtonSave()
{
	setlocale(LC_CTYPE, "chs");
	CString FileName;
	CFileDialog dlgFile(FALSE, _T("*.txt"), NULL, OFN_HIDEREADONLY, _T("Describe File(*.txt)|*.txt|All Files(*.*)|*.*||"), NULL);
	if (IDOK == dlgFile.DoModal())
	{
		FileName = dlgFile.GetPathName();
	}
	else
	{
		return;
	}

	CStdioFile FileWrite;
	if (!FileWrite.Open(FileName, CFile::modeWrite | CFile::modeCreate | CFile::typeText))
	{
		AfxMessageBox(_T("打开文件失败!"));
		return;
	}

	CString CaptionData = _T("");
	CaptionData = CaptionData + _T("批次	");
	FileWrite.WriteString(CaptionData + _T("\r\n"));

	for (int i = 0; i <9; i++)
	{
		CString temp;
		temp.Format(_T("%d	"), i);//需要保存的数据，注意格式
		FileWrite.WriteString(temp);
		FileWrite.WriteString(_T("\r\n"));
	}
	FileWrite.Close();
}

结果如下：
