怎样用vb点虐 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点虐 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

关于VB.NET制作记事本自动保存的问题

分类: 电脑/网络 程序设计 其他编程语言

问题描述:

我用的是Timer计时器：

如何将程序控制住，让它第一次发现没保存后，只击活一次提示保存，然后使用修改后的保存路径：（代码如下）

Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick

'如何将程序控制住，让它第一次发现没保存后，只击活一次提示保存，然后使用修改后的保存路径

If SaveFileDialog1.FileName = "" Then

If SaveFileDialog1.ShowDialog Then

rtbox.SaveFile(SaveFileDialog1.FileName, RichTextBoxStreamType.PlainText)

End If

Else

'如果已经选择了要保存的文件名，则保存文本到文件中

rtbox.SaveFile(SaveFileDialog1.FileName, RichTextBoxStreamType.PlainText)

End If

End Sub

————————————————————

此代码执行后变成死循环。

解析:

经过我的潜心修炼问题终于是解决了.请看代码

Imports System.IO

Private strFileName As String = "myRTFdoc.txt"

Private flgFirst As Boolean = True

Private Sub Timer2_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer2.Tick

'如何将程序控制住，让它第一次发现没保存后，只击活一次提示保存，然后使用修改后的保存路径

Call zc()

End Sub

Private Sub zc()

'Timer2.Stop()

With SaveFileDialog1

.DefaultExt = "txt"

.FileName = strFileName

.Filter = "Text files(*.txt)|*.txt|All files(*.*)|*.*"

.FilterIndex = 1

.InitialDirectory = "c:\"

.OverwritePrompt = True

.Title = "Save Reminding"

End With

'Timer2.Enabled = False

If flgFirst = True Then

If SaveFileDialog1.ShowDialog = DialogResult.OK Then

strFileName = SaveFileDialog1.FileName

Dim objWriter As StreamWriter = New StreamWriter(strFileName, False)

objWriter.Write(rtbox.Text)

objWriter.Close()

objWriter = Nothing

End If

flgFirst = False

'Timer2.Enabled = True

' Timer2.Start()

Else

'flg= second

Dim objWriter As StreamWriter = New StreamWriter(strFileName, False)

objWriter.Write(rtbox.Text)

objWriter.Close()

objWriter = Nothing

End If

'Timer2.Enabled = True

'Timer2.Start()

End Sub

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

Timer2.Enabled = True

' zc()

End Sub

知道问题在哪里嘛?我调试了确实是"死循环"、其实不是真正的死循环、是time tick事件你设定的时间太短了.估计只设置了1-5s左右.那么程序运行还需要时间.所以他就不停地调用timetick时间.你的savedialog对话框根本来不急弹出来.

所以建议你把timer的interval的值设置高点最好12-15秒 触发一次.

当然我想还有其他的方法、还没有彻底取研究下.

比如stop 什么 、那还需要时间.

至少目前我的方法是可以了.

我设置的12s P4. 3.0 1G 内存 跑下我的程序如果 F10(F8)慢点的话就来不及了.

另为把你的程序小改了下、应该可以满足你的要求了.
