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.
