[C#] Region 註解

用來 Mark 大範圍程式碼 區塊 ，識別使用

使用後效果

[C#] enum 列舉

剛剛伙伴教我的，第一次使用

用來做流程控制最好了，而且還支援中文  :)

[C#] FTP 下載單一檔案（WebClient）

網路上有說，使用 WebClient 的作法碰到取很大檔案時 會有 timeout 問題，
目前自己測試 16MB 單檔是沒有問題。

using System.Net;
using System.IO;
----------------------------------
WebClient RMS = new WebClient();
RMS.Credentials = new NetworkCredential("ubuntu", "zzzzzz");
string FILE_NAME = "新增文字文件.txt";
byte[] fildData = RMS.DownloadData("ftp://10.1.1.195/tools/"+FILE_NAME);
FileStream file = File.Create(@"C:\Users\kuoming\Desktop\" + FILE_NAME);
file.Write(fildData, 0, fildData.Length);
file.Close();
listBox1.Items.Add(FILE_NAME);

[Other] Firefox Javascript 可以只顯示文字的語法

有時候遇到很多圖片的網頁，可是只是想要 看文字的部分。所以把文字放大，背景顏色套用白色
 
可以存成『我的最愛』連結，當按下連結就可以套用了。

javascript:(function(){var%20newSS,%20styles='*%20{%20background:%20white%20!%20important;%20color:%20black%20!important;%20line-height:%20160%%20!important;%20font-size:%2018pt%20!important%20}%20:link,%20:link%20*%20{%20color:%20#0000EE%20!important%20}%20:visited,%20:visited%20*%20{%20color:%20#551A8B%20!important%20}';%20if(document.createStyleSheet)%20{%20document.createStyleSheet(%22javascript:'%22+styles+%22'%22);%20}%20else%20{%20newSS=document.createElement('link');%20newSS.rel='stylesheet';%20newSS.href='data:text/css,'+escape(styles);%20document.getElementsByTagName(%22head%22)[0].appendChild(newSS);%20}%20})();

  
原本樣式

          

套用後樣式

[C#] Listview

  

Listview 是很好用，之前一直都用 Listbox 來做，最近才開始接觸。。

 

   1: listView1.Clear(); //清空 listview

   2:            listView1.View = View.Details; //設定模式為 清單模式

   3:            listView1.GridLines = true; //繪製 格線

   4:            listView1.FullRowSelect=true; //ture 一次選擇一行  ; false 一次選一格 

   5:            listView1.MultiSelect = false; //不可選多行

   6:            listView1.Scrollable = true; //需要的時候 自動顯示 滾動條

   7:            listView1.HeaderStyle = ColumnHeaderStyle.Nonclickable; //設定點選 標題項目不動作

   8:            listView1.Columns.Add("機種",150,HorizontalAlignment.Left);  //設定標題,寬度,位置

   9:            listView1.Columns.Add("55階",180,HorizontalAlignment.Left);

  10:  

  11:            for (int i = 0; i < 1; i++)

  12:            {

  13:                ListViewItem LM = new ListViewItem(comboBox1.Text.ToString());

  14:  

  15:                LM.SubItems.Add("1");

  16:              

  17:                listView1.Items.AddRange(new ListViewItem[] { LM });

  18:            }

 

排序的部分（CLASS）

   1: class ListViewItemComparer : IComparer

   2: {

   3:     private int col;

   4:     public ListViewItemComparer()

   5:     {

   6:         col = 0;

   7:     }

   8:     public ListViewItemComparer(int column)

   9:     {

  10:         col = column;

  11:     }

  12:     public int Compare(object x, object y)

  13:     {

  14:         return String.Compare(((ListViewItem)x).SubItems[col].Text, ((ListViewItem)y).SubItems[col].Text);

  15:     }

  16: }

用法

   1: //排序 Listiew 4

   2: this.listView4.ListViewItemSorter = new ListViewItemComparer(listView4.Columns[5].Index);

   3: listView4.Sort();
