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 fileGetPrivateProfileString(SECTION_USERINFO, "UserName", "", userName, 63, sIniFile); // read a string from the specified config fileGetPrivateProfileString(SECTION_USERINFO, "Password", "", password, 63, sIniFile);score_Chinese = GetPrivateProfileInt(SECTION_SCORE, "Chinese", 0, sIniFile); // read an integer from the specified config filescore_Mathematics = GetPrivateProfileInt(SECTION_SCORE, "Mathematics", 0, sIniFile);// Update values to the controlsCString 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 herechar 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 fileCString 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
