怎樣用vb.net做記事本？？

簡單的 用TextBox 或者RichTextBox 控件啊 至于文件 可以存為ANSIC編碼的文本文件 或者數據庫存取也行啊

怎樣在VB .NET中調用記事本和計算器

這個啊，呵呵，應該不難吧

先找到你要打開的應用程序的文件

然后用一個調用代碼：

System.Diagnostics.Process.Start("C:\WINDOWS\system32\notepad.exe")

這是要開記事本的

System.Diagnostics.Process.Start("C:\WINDOWS\system32\calc.exe")

這是打開計算器的

應該也可以把這兩個應用程序復制到你的程序的默認目錄下，就是BIN下吧！

呵呵，試試??！要給我加分哦?。。?/p>

VB.net怎么才能實現記事本中的查找上一個的功能(在Richtextbox中)？

查找一次后記入查找內容的位置，百查找下一個功能度 這時候的開始位置就是剛才查找內容的位置加上查找內容的長度，版突出顯示其實就是選權定文本，富文本框有SelectionStart，SelectionLength 兩個屬性
