    篇四:关于OneNote入库处理以及审核:http://www.cnblogs.com/baiboy/p/wpf3.html


    【小记】:大胆尝试才能突破,某个中医药大学有一批图片需要处理(OCR),然后进行数据挖掘。之前没有接触过OCR这个东西,但是还是应允了。在网上搜索一番,关于中文图片识别,最终敲定为基于微软的OneNote,其识别率相对较高。网上这个技术点的资料真心不多,后来于博客园找到一篇博文,但是那个程序还是bug百出,而且只是单处理。后来经过一番摸索逐个突破,批处理完成。然后进行界面设计,这些零碎工作完成后,便是入库处理。由于OneNote生成的xml文件封装好的,即不可视的。便将其代码处理生成txt文件,再进行Oracle入库处理。入库前需要文件内容审核,并且在WPF开发中数据绑定和分页中做了独特处理。现在经过半个月的工作,本项目做个阶段总结。一则知识总结便于二次开发,尽量保持程序流畅性,核心知识做以梳理;另外,相关WPFOneNote常用技术共享,便于部分园友所需。本人技术有限,欢迎交流。项目还未结束,暂作阶段文章发布,随后相继发布。


    篇四:关于OneNote入库处理以及审核

    【开篇概述】:文本作为系列文章的最后一篇,主要对页面进行设计布局和审核页面的完善,其中主页面用户可以查询审核通过的信息,浏览详细信息。也可以作为导航到orc页面,对批量图片进行文字处理,处理后的文件,可以通过入库页面对文件信息提取。达到半自动填写表格的状态,由于文件信息不一定符合主观要求或者格式不一致,所以设置了审核页面,也是信息修改页面,信息无误后,选择下面审核通过复选框即可成功入库。后面就是交付做数据挖掘处理了。效果如图所示

            }
        }
    }
    View Code

    【功能以及操作描述】

    1. 打开主页面可以看到,每条信息前序号的生成,通过后台对事件重写完成,代码如下。
              void MainWindow_Loaded(object sender, RoutedEventArgs e)
              {
                  this.c1.Children.Add(page1);
                  this.Loaded += delegate
                  {
                      InitData();
                  };
                  dataGrid1.LoadingRow += new EventHandler<DataGridRowEventArgs>(dataGrid1_LoadingRow);
              }
              void dataGrid1_LoadingRow(object sender, DataGridRowEventArgs e)
              {
                  e.Row.Header = e.Row.GetIndex() + 1;    //设置行表头的内容值   
              }
      View Code
        
    2. 页面自动显示为分页显示,通过用户控件进行分页,然后对数据控件进行绑定,详细操作见系列二文章。本功能代码如下:
       //查询
              private void InitData()
              {
                  string sql = "select * from T_TCM_THESIS where auditflag=1  order by ID desc";
                  DataSet ds = MYHelper.SQLHelper.GetOrlData(sql);
                  if (ds.Tables[0].Rows.Count > 0)
                  {
                      page1.ShowPages(this.dataGrid1, ds, 10);
                  }
                  else
                  {
                      System.Windows.Forms.MessageBox.Show("Erroy");
                  }
              }
      View Code
    3. 点击详细信息按钮,跳转的详细信息页面。如何获取DataGrid主键是关键,具体实现为:
                  this.Hide();
                  DataRowView mySelectedElement = (DataRowView)dataGrid1.SelectedItem;
                  int ID = Convert.ToInt32((mySelectedElement.Row[0]));  //获取该行的FID  
                  falg f = new falg(ID,0);
                  f.Show();
    4. 在目标页面,通过页面接受页面传值,显示到详细信息。
       private void THESIS(int id)
              {
                  string sql = "select * from T_TCM_THESIS where id="+id;
      
                  DataTable dt = MYHelper.SQLHelper.GetTabOrlData(sql);
                  if (dt.Rows.Count>0)
                  {
                      txtdocname.Text = dt.Rows[0]["docname"].ToString();
                      txtauthor.Text = dt.Rows[0]["author"].ToString();
                      txtcompany.Text = dt.Rows[0]["authorcompany"].ToString();
                      txtcontent.Text = dt.Rows[0]["content"].ToString();
                      txtdigest.Text = dt.Rows[0]["digest"].ToString();
                      txtdisease.Text = dt.Rows[0]["disease"].ToString();
                      txtdoctype.Text = dt.Rows[0]["doctype"].ToString();
                      txtenglishtitle.Text = dt.Rows[0]["englishtitle"].ToString();
                      txtkeyword.Text = dt.Rows[0]["keyword"].ToString();
                      txtmemo.Text = dt.Rows[0]["memo"].ToString();
                      txtpath.Text = dt.Rows[0]["path"].ToString();
                      txtsource.Text = dt.Rows[0]["source"].ToString();
                      txtsourcetype.Text = dt.Rows[0]["sourcetype"].ToString();
                      txtsummary.Text = dt.Rows[0]["summary"].ToString();
                      txttitle.Text = dt.Rows[0]["title"].ToString();
                      txtyears.Text = dt.Rows[0]["years"].ToString();
                      int flag =Convert.ToInt32(dt.Rows[0]["auditflag"].ToString());
                      if (flag == 1)
                      {
                          cbflag.IsChecked = true;
                      }
                      else
                      {
                          cbflag.IsChecked = false;
                      }
                  }
              }
      View Code
    5. 审核页面的具体操作也是类似, 不同之处在于对传值页面进行逻辑判断,如果是审核则允许页面信息的更新,如果查看详细信息,则更新按钮隐藏。

     


     【篇末】:截止到此,本程序完全结束,本章涉及页面传值和数据绑定等基本信息,这方面大体与winfrom操作一致。本程序采用讲涉及的知识点数十个,均一一列出整理。数据库sql文件在项目的db文件夹中,附上完整源码如下:

     

    注:源码地址链接总是不正确,后来打开管理--〉文件,查看源码,找到本文件的链接地址粘贴即可。
