相关问答
Q1: 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 程序怎么默认打开txt记事本文件？
楼下的根本不对。exe右键是没有“打开方式”的，也没必要因为这个问题而还原系统。把exe设置为直接运行，方法：新建一个txt文件，输入ftype exefile="%1" %* ，保存，把扩展名改为bat，双击这个文件，就好了。
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
Q4: 怎样在VB .NET中调用记事本和计算器
这个啊，呵呵，应该不难吧
先找到你要打开的应用程序的文件
然后用一个调用代码：
System.Diagnostics.Process.Start("C:\WINDOWS\system32\notepad.exe")
这是要开记事本的
System.Diagnostics.Process.Start("C:\WINDOWS\system32\calc.exe")
这是打开计算器的
应该也可以把这两个应用程序复制到你的程序的默认目录下，就是BIN下吧！
呵呵，试试！！要给我加分哦！！！
