用 CFileDialog 控件获取文件打开或保存的文件名。 b.自定义一个测量点数据结构体，其元素包括：点号，编码，X,Y,H c.用文本框显示原始数据和整理后的数据 d..按编程规范进行编码

a. 使用CFileDialog控件获取文件名的代码示例：

CFileDialog dlg(TRUE, NULL, NULL, OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT, _T("Text Files (*.txt)|*.txt|All Files (*.*)|*.*||"), NULL);
if (dlg.DoModal() == IDOK)
{
    CString strFilePath = dlg.GetPathName();
    // 处理文件名
}

b. 自定义测量点数据结构体的代码示例：

struct MeasurePoint
{
    int pointNo;    // 测量点号
    CString code;   // 编码
    double x;       // X坐标
    double y;       // Y坐标
    double h;       // 高程
};

c. 显示原始数据和整理后数据的代码示例：

// 原始数据
CString strRawData;
strRawData.Format(_T("%d %s %.3f %.3f %.3f\r\n"), measurePoint.pointNo, measurePoint.code, measurePoint.x, measurePoint.y, measurePoint.h);
m_editRawData.SetWindowText(strRawData);

// 整理后数据
CString strCleanData;
strCleanData.Format(_T("%d,%s,%.3f,%.3f,%.3f\r\n"), measurePoint.pointNo, measurePoint.code, measurePoint.x, measurePoint.y, measurePoint.h);
m_editCleanData.SetWindowText(strCleanData);

d. 编程规范要求代码风格整洁、命名规范规范、注释清晰等，以下是示例代码的一个完整示例：

// 定义测量点数据结构体
struct MeasurePoint
{
    int pointNo;    // 测量点号
    CString code;   // 编码
    double x;       // X坐标
    double y;       // Y坐标
    double h;       // 高程
};

// 打开文件对话框获取文件名
CFileDialog dlg(TRUE, NULL, NULL, OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT, _T("Text Files (*.txt)|*.txt|All Files (*.*)|*.*||"), NULL);
if (dlg.DoModal() == IDOK)
{
    // 获取文件名并打开文件
    CString strFilePath = dlg.GetPathName();
    FILE* fp = _wfopen(strFilePath, _T("r"));

    if (fp != NULL)
    {
        // 读取文件内容并解析数据
        CString strLine;
        while (fgetws(strLine.GetBufferSetLength(1024), 1024, fp) != NULL)
        {
            MeasurePoint measurePoint;
            int nFields = _stscanf_s(strLine, _T("%d %s %lf %lf %lf"), &measurePoint.pointNo, measurePoint.code.GetBufferSetLength(64), &measurePoint.x, &measurePoint.y, &measurePoint.h);

            if (nFields == 5)
            {
                // 原始数据
                CString strRawData;
                strRawData.Format(_T("%d %s %.3f %.3f %.3f\r\n"), measurePoint.pointNo, measurePoint.code, measurePoint.x, measurePoint.y, measurePoint.h);
                m_editRawData.SetWindowText(strRawData);

                // 整理后数据
                CString strCleanData;
                strCleanData.Format(_T("%d,%s,%.3f,%.3f,%.3f\r\n"), measurePoint.pointNo, measurePoint.code, measurePoint.x, measurePoint.y, measurePoint.h);
                m_editCleanData.SetWindowText(strCleanData);
            }
        }

        // 关闭文件
        fclose(fp);
    }
}
