怎样用vb.net做记事本？？

简单的用TextBox 或者RichTextBox 控件啊至于文件可以存为ANSIC编码的文本文件或者数据库存取也行啊

vb.net如何用我编写的一个记事本程序通过鼠标右键菜单来打开一个文件

一、用wshshell组件的RegWrite方法写注册表，在HKEY_CLASSES_ROOT\*\Shell 位置加入的你程序，

例如：

[HKEY_CLASSES_ROOT\*\shell\我的程序\command]

@="D:\\我的程序.exe %1"

后面的%1会将文件名传送给你的程序的Command$，多文件名需要使用DDE方式进行互斥传入。

二、

将下面内容输入记事本后保存为reg文件，运行即可：

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\*\shell]

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\*\shell\OpenInNotepad]

@="用记事本打开"

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\*\shell\OpenInNotepad\command]

@="notepad.exe %1"

"用记事本打开" 为右键菜单中显示的名称

VB.NET做一个类似记事本的可执行文件，保存时不知道怎么用代码设置保存类型（文件扩展名）

算了，都贴上，你自己看吧：

//设置文件类型

//书写规则例如：txt files(*.txt)|*.txt

saveFileDialog.Filter = "txt files(*.txt)|*.txt|xls files(*.xls)|*.xls|All files(*.*)|*.*"

//设置默认文件名（可以不设置）

saveFileDialog.FileName = "siling-Data"

//主设置默认文件extension（可以不设置）

saveFileDialog.DefaultExt = "xml"

//获取或设置一个值，该值指示如果用户省略扩展名，文件对话框是否自动在文件名中添加扩展名。（可以不设置）

saveFileDialog.AddExtension = true

//设置默认文件类型显示顺序（可以不设置）

saveFileDialog.FilterIndex = 2

//保存对话框是否记忆上次打开的目录

saveFileDialog.RestoreDirectory = true
