【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（ORC），然后进行数据挖掘。之前没有接触过ORC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WPF和OneNote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
主页面：
完整代码：
namespace OnenoteOCRDemo { /// <summary> /// Index.xaml 的交互逻辑 /// </summary> public partial class Index : Window { public Index() { InitializeComponent(); this.Loaded += new RoutedEventHandler(MainWindow_Loaded); } page page1 = new page(); 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 } //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"); } } private void Window_Loaded(object sender, RoutedEventArgs e) { InitData(); } private void hlorc_Click(object sender, RoutedEventArgs e) { Main m = new Main(); m.Show(); } private void hltext_Click(object sender, RoutedEventArgs e) { TextData td = new TextData(); td.Show(); } //刷新 private void hlnew_Click(object sender, RoutedEventArgs e) { InitData(); } private void hyper2_Click(object sender, RoutedEventArgs e) { 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(); } } }
审核页面：
完整代码：
namespace OnenoteOCRDemo { /// <summary> /// falg.xaml 的交互逻辑 /// </summary> public partial class falg : Window { int i; public falg(int id,int n) { InitializeComponent(); txt.Text = id.ToString(); THESIS(id); i = n; if (i == 0) { btnupdate.Visibility = System.Windows.Visibility.Hidden; cbflag.Visibility = System.Windows.Visibility.Hidden; txtflag.Text="审核通过"; } } 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; } } } public void TextIsNull() { txtdocname.Text = ""; txtyears.Text = ""; txtdoctype.Text = ""; txtsummary.Text = ""; txtauthor.Text = ""; txtsource.Text = ""; txtsourcetype.Text = ""; txtmemo.Text = ""; txttitle.Text = ""; txtenglishtitle.Text = ""; txtcompany.Text = ""; txtkeyword.Text = ""; txtcontent.Text = ""; txtdigest.Text = ""; txtpath.Text = ""; txtdisease.Text = ""; cbflag.IsChecked = false; } //审核信息（更新信息） private void btnupdate_Click(object sender, RoutedEventArgs e) { int id=Convert.ToInt32( txt.Text); string docname = txtdocname.Text.ToString(); string years = txtyears.Text.ToString(); string doctype = txtdoctype.Text.ToString(); string summary = txtsummary.Text.ToString(); string author = txtauthor.Text.ToString(); string source = txtsource.Text.ToString(); string sourcetype = txtsourcetype.Text.ToString(); string memo = txtmemo.Text.ToString(); string title = txttitle.Text.ToString(); string englishtitle = txtenglishtitle.Text.ToString(); string authorcompany = txtcompany.Text.ToString(); string keyword = txtkeyword.Text.ToString(); string content = txtcontent.Text.ToString().Trim(); string digest = txtdigest.Text.ToString(); string path = txtpath.Text.ToString(); string disease = txtdisease.Text.ToString(); int auditflag; if (cbflag.IsChecked == true) { auditflag = 1; } else { auditflag =0; } try { string sql = "update T_TCM_THESIS set docname=‘" + docname + "‘,years=‘" + years + "‘,doctype=‘" + doctype + "‘,summary=‘" + summary + "‘,"; sql += "author=‘" + author + "‘,source=‘" + source + "‘,sourcetype=‘" + sourcetype + "‘,memo=‘" + memo + "‘,title=‘" + title + "‘,"; sql += "englishtitle=‘" + englishtitle + "‘,authorcompany=‘" + authorcompany + "‘,keyword=‘" + keyword + "‘,content=‘" + content + "‘,digest=‘" + digest + "‘,"; sql += "path=‘" + path + "‘,disease=‘" + disease + "‘,auditflag=" + auditflag + " where ID= "+id; int i = SQLHelper.OrlExecuteQuery(sql); if (i > 0) { System.Windows.Forms.MessageBox.Show("审核通过", "审核信息"); TextIsNull(); this.Close(); TextData td = new TextData(); td.Show(); } else { System.Windows.Forms.MessageBox.Show("审核失败", "审核信息"); } } catch (Exception ex) { System.Windows.Forms.MessageBox.Show(ex.Message); } } private void btnback_Click(object sender, RoutedEventArgs e) { this.Close(); if (i == 1) { TextData td = new TextData(); td.Show(); } else { Index index = new Index(); index.Show(); } } } }
【功能以及操作描述】
-
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。
View Code
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 }
- 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：
View Code
//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"); } }
- 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();
- 在目标页面，通过页面接受页面传值，显示到详细信息。
View Code
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; } } }
- 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：
