雖然自己已經有固定愛用的品牌，但女人嘛...總是會手滑亂買東西...(汗)
你看看、你看看，這一大堆的洗面乳，是多大一張臉，需要用到這麼多瓶阿~~~

這個範例程式，會顯示進度字串到textbox內，textbox會自動捲動到最下方，會顯示進度條(0~100)，可讓使用者中斷程序。
VB部分的程式碼我是用網路上C#toVB轉換器轉的，所以不知道有無錯誤，請網友費心試試看囉~

程式元件畫面：

//C#

//開啟檔案
OpenFileDialog OpenFileDialog1 = new OpenFileDialog();
OpenFileDialog1.CheckFileExists = true;
OpenFileDialog1.Filter = "txt files (*.txt)|*.txt";
OpenFileDialog1.Multiselect = false;
OpenFileDialog1.ShowDialog();
TextBox.Text = OpenFileDialog1.FileName;

//開啟資料夾
FolderBrowserDialog FolderBrowserDialog1= new FolderBrowserDialog();
FolderBrowserDialog1.ShowDialog();
TextBox.Text = FolderBrowserDialog1.SelectedPath;

'VB

'開啟檔案

//檢查檔案是否存在
if (!File.Exists(FilePath))

    if (sLine != null)
    {
        arrText.Add(sLine);

objReader.Close();

//把讀取檔案的結果放到ListBox，您也可以另做運用。
ListBox.Items.AddRange(arrText);
