本文介绍了一个使用MFC创建的应用程序如何通过按钮点击事件来读取和写入INI文件的具体实现方法。该程序能够从配置文件中读取用户名、密码及分数等信息并显示出来，同时也支持将编辑框中的数据保存回INI文件。

新建一个dialog based MFC Windows Application,命名为：d, 界面为：

为按钮Read和Write添加单击事件，并自定义一个函数GetIniFileName()用来取得ini文件的路径，主要函数代码如下：

// read data from config file
void CDDlg::OnBtnRead()							// 从INI文件中读取指定的信息，更新到编辑框中
{
	char userName[64], password[64];
	int score_Chinese, score_Mathematics;
	CString sIniFile = GetIniFileName();		// 取得配置文件全路径

memset(userName, 0, sizeof(userName));		// 填充字符串数组
	memset(password, 0, sizeof(password));

// read values from the specified config file
	GetPrivateProfileString(SECTION_USERINFO, "UserName", "", userName, 63, sIniFile);	// read a string from the specified config file
	GetPrivateProfileString(SECTION_USERINFO, "Password", "", password, 63, sIniFile);
	score_Chinese = GetPrivateProfileInt(SECTION_SCORE, "Chinese", 0, sIniFile);			// read an integer from the specified config file
	score_Mathematics = GetPrivateProfileInt(SECTION_SCORE, "Mathematics", 0, sIniFile);

// Update values to the controls
	CString tempValue;
	((CEdit*) GetDlgItem(IDC_EDIT_USERNAME))->SetWindowText(userName);
	((CEdit*) GetDlgItem(IDC_EDIT_PASSWORD))->SetWindowText(password);
	tempValue.Format("%d", score_Chinese);
	((CEdit*) GetDlgItem(IDC_EDIT_CHINESE))->SetWindowText(tempValue);		// 10：代表十进制
	tempValue.Format("%d", score_Mathematics);
	((CEdit*) GetDlgItem(IDC_EDIT_MATHEMATICS))->SetWindowText(tempValue);

MessageBox("Read data from config file successfully!", "Information", MB_OK | MB_ICONINFORMATION);
//	((CStatic *) GetDlgItem(IDC_TXT_MESSAGE))->SetWindowText("Read data from config file successfully!");
}

// store data to config file
void CDDlg::OnBtnwrite()
{
	// TODO: Add your control notification handler code here
	char userName[64], password[64], sValue[20];
	int score_Chinese, score_Mathematics;

((CEdit *) GetDlgItem(IDC_EDIT_USERNAME))->GetWindowText(userName, 63);
	((CEdit *) GetDlgItem(IDC_EDIT_PASSWORD))->GetWindowText(password, 63);
	((CEdit *) GetDlgItem(IDC_EDIT_CHINESE))->GetWindowText(sValue, 19);
	score_Chinese = atoi(sValue);
	((CEdit *) GetDlgItem(IDC_EDIT_MATHEMATICS))->GetWindowText(sValue, 19);
	score_Mathematics = atoi(sValue);

// Write data to the config file
	CString sIniFile = GetIniFileName();
	CString tempValue;
	WritePrivateProfileString(SECTION_USERINFO, "UserName", userName, sIniFile);
	WritePrivateProfileString(SECTION_USERINFO, "Password", password, sIniFile);
	tempValue.Format("%d", score_Chinese);
	WritePrivateProfileString(SECTION_SCORE, "Chinese", tempValue, sIniFile);
	tempValue.Format("%d", score_Mathematics);
	WritePrivateProfileString(SECTION_SCORE, "Mathematics", tempValue, sIniFile);

MessageBox("Write data to config file successfully!", "Information", MB_OK | MB_ICONEXCLAMATION);
//	((CStatic *) GetDlgItem(IDC_TXT_MESSAGE))->SetWindowText("Write data to config file successfully!");
}

// get the file path of config file
CString CDDlg::GetIniFileName() const
{
	CString Result, sPath;
	Result = _T("");
	char sFileName[256];
	GetModuleFileName(AfxGetInstanceHandle(), sFileName, 255);	// 取得当前可执行文件的路径，保存在sFileName中
	sPath = sFileName;
	int index = sPath.ReverseFind('\\');						// 逆向查找指定字符
	sPath = sPath.Left(index);
	Result = sPath + "\\Config.ini";
	
	return Result;
}

其中，ini文件中的内容为：

[UserInfo]
UserName=tian
Password=123456zhou

[Score]
Chinese=55
Mathematics=66
