txt文件增加内容 - 专家坐堂 - Foxtable(狐表) - 新一代数据库软件，完美融合Access、Foxpro、Excel、vb.net之优势，人人都能掌握的快速软件开发工具!

现在生成的txt内容是

env_00230248773.dat    sn: 00230248773    mac: 9845.62fa.4a20
env_00230248774.dat    sn: 00230248774    mac: 9845.62fa.4a30
env_00230248775.dat    sn: 00230248775    mac: 9845.62fa.4a40

希望能做成下面内容，相比原txt增加了key和ssid。key是随机生成的8位都是小写，ssid是有DDTV-和mac地址后6位组成，都是大写。

env_00230248773.dat    sn: 00230248773    mac: 9845.62fa.4a20    key: wueyeq5x    ssid: DTTV-FA4A20
env_00230248774.dat    sn: 00230248774    mac: 9845.62fa.4a30    key: r7fywazv ssid: DTTV-FA4A30
env_00230248775.dat    sn: 00230248775    mac: 9845.62fa.4a40    key: d72ea9m3    ssid: DTTV-FA4A40

click代码:

Dim startSN As WinForm.TextBox = e.Form.Controls("TextBox11")

Dim xqsl As WinForm.TextBox = e.Form.Controls("TextBox22")

Dim endsn As WinForm.TextBox = e.Form.Controls("TextBox55")

Dim epromlj As WinForm.TextBox = e.Form.Controls("TextBox88")

Dim txtlj As WinForm.TextBox = e.Form.Controls("TextBox01")

Dim id11 As Integer = CInt(startSN.text)

Dim id22 As Integer = CInt(xqsl.text)

Dim id33 As Integer = id11 + id22 - 1

Endsn.text = id33

Dim inilj As WinForm.TextBox = e.Form.Controls("TextBox44")

Dim iniwj As WinForm.TextBox = e.Form.Controls("TextBox33")

Dim pfid As Integer = Inilj.text .IndexOf(":")

Dim pfwj As String = Inilj.text.Substring(0,pfid + 1)

Dim id As Integer = inilj.text.lastindexof("\")

Dim lj As String = inilj.text.Substring(0,id) & "\"

Dim p As new Process()

p.StartInfo.FileName = "cmd.exe"

p.StartInfo.UseShellExecute = False '关闭Shell的使用

p.StartInfo.RedirectStandardInput = True '重定向标准输入

p.StartInfo.RedirectStandardOutput = True '重定向标准输出

p.StartInfo.RedirectStandardError = True '重定向错误输出

p.StartInfo.CreateNoWindow = False '设置不显示窗口

p.Start()

p.StandardInput.WriteLine(pfwj)

p.StandardInput.WriteLine("cd" & " " & lj)

p.StandardInput.WriteLine(e.Form.Controls("TextBox7").text & " " & e.Form.Controls("TextBox11").Text & " " & e.Form.Controls("TextBox22").Text & " " & e.Form.Controls("TextBox33").Text, 1)

p.StandardInput.WriteLine("exit")

Dim id3 As Integer = Iniwj.text.IndexOf(".")

Dim Iniwjlj As String = Iniwj.text.SubString(0,id3)

Dim txtstr As String = Iniwjlj & "(" & e.Form.Controls("TextBox11").text & "-" & e.Form.Controls("TextBox55").text & ")" & ".txt"

txtlj.text = lj & txtstr 'txtljtxt这个文件怎么处理才能实现这个需求呢？

epromlj.text = lj

MessageBox.show("INI文件:" & e.Form.Controls("TextBox33").Text & vbcrlf & "需求数量:" & e.Form.Controls("TextBox22").Text & vbcrlf & "生成目录:" & lj,"eprom生成完成",MessageBoxButtons.OK,MessageBoxIcon.Information )

比如

Dim s As String = "env_00230248773.dat sn: 00230248773 mac: 9845.62fa.4a20"

s = s & " key:" & Rand.NextString(8).ToLower & " ssid: " & right(s,7).replace(".","").ToUpper

msgbox(s)

Dim txtstr As String = Iniwjlj & "(" & e.Form.Controls("TextBox11").text & "-" & e.Form.Controls("TextBox55").text & ")" & ".txt"

txtlj.text = lj & txtstr 'txtljtxt这个文件怎么处理才能实现这个需求呢?

epromlj.text = lj

msgbox(0)

Dim strs As String = FileSys.ReadAllText(lj & txtstr)

strs = strs.Replace(vblf,"")

Dim rs() As String = strs.Split(vbcr)

For i As Integer = 0 To rs.Length - 1

strs = strs & " key:" & Rand.NextString(8).ToLower & " ssid:DTTV- " & right(rs(i),7).replace(".","").ToUpper

txtstr = strs

没实现。请帮忙看看哪里问题？

Dim txtstr As String = Iniwjlj & "(" & e.Form.Controls("TextBox11").text & "-" & e.Form.Controls("TextBox55").text & ")" & ".txt"

txtlj.text = lj & txtstr 'txtljtxt这个文件怎么处理才能实现这个需求呢?

epromlj.text = lj

Dim strs As String = FileSys.ReadAllText(lj & txtstr)

msgbox(strs )

strs = strs.Replace(vblf,"")

Dim rs() As String = strs.Split(vbcr)

For i As Integer = 0 To rs.Length - 1

strs = strs & rs(i) & " key:" & Rand.NextString(8).ToLower & " ssid:DTTV- " & right(rs(i),7).replace(".","").ToUpper

txtstr = strs

试了还是发现原txt没改。

msgbox(strs )

txtstr = strs

msgbox(txtstr )

msgbox显示是加到了txt最后面，而不是每行增加。

另外原txt内容也没变。

既然知道问题了就对应解决咯

先把原来的变量值清空，再合并。或者定义一个新的变量

原txt内容，因为根本就没有把结果重新赋值回原txt的代码
