包含vb.net做记事本的词条

VB.NET写一个记事本程序,如何用程序让使用者编辑好的内容独立的存在硬盘上?

你是说记事本的配置吧，

如果设置不是太大，可以保存在注册表中，

另外可以用xml文件或者ini文件来保存配置，

不知道有没理解错你的意思

Q2: VB.net怎么才能实现记事本中的查找上一个的功能(在Richtextbox中)？

查找一次后记入查找内容的位置，百查找下一个功能度 这时候的开始位置就是刚才查找内容的位置加上查找内容的长度，版突出显示其实就是选权定文本，富文本框有SelectionStart，SelectionLength 两个属性

Q3: 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
