    ABOUT STRING READING FROM textfile

    Hello,
    I got a text file with that kind of data

    ALARM= ALARM1
    ZONE= ZONE6
    DESCRIPTION= NEED TO REPLACE

    ALARM= ALARM5
    ZONE= ZONE5
    DESCRIPTION= OK FOR 2 YEAR

    ALARM= ALARM9
    ZONE= ZONE7
    DESCRIPTION= NEED MAINTANENCE


    When textfile contain "ALARM=" i can load alarm name to listbox with the code below and display
    ALARM1
    ALARM5
    ALARM9 on the listbox

    '+++++++++++++++++++++++++

    Private Sub Command1_Click()
    nFileNum = FreeFile
    Open "C:\3.txt" For Input As nFileNum
    lLineCount = 1
    Do While Not EOF(nFileNum)
    Line Input #nFileNum, sNextLine
    sNextLine = sNextLine & vbCrLf
    sText = sNextLine

    If InStr(sText, "ALARM=") = 1 Then

    List1.AddItem (Mid(sText, 7, (Len(sText) - 7)))

    End If

    Loop

    Close nFileNum

    End Sub

    '++++++++++++++++++

    What i want now is this function

    Private Sub List1_Click()
    text1.text= ?????????
    End Sub

    I mean ,when i click ALARM1 on list item i want to display
    ALARM= ALARM1
    ZONE= ZONE6
    DESCRIPTION= NEED TO REPLACE


    When i click ALARM9 on list item i want to display
    ALARM= ALARM9
    ZONE= ZONE7
    DESCRIPTION= NEED MAINTANENCE

    And so on, there is one space line between these group.

    I have attach my sample project. That will be great if anyone can find the solution.

    Many thanks

    Re: ABOUT STRING READING FROM textfile

    hmmm... from your code I bet the entries into the list box are not quite what you are expecting...
    Code:
    If Left(sNextLine, 6) = "ALARM=" Then
      List1.AddItem sNextLine
      Redim Preserve MyArray(List1.ListCount) As String
      MyArray(List1.ListCount) = sNextLine
    Else
      MyArray(List1.ListCount) = MyArray(List1.ListCount) & sNextLine
    End If
    Then...
    Code:
    Private Sub List1_Click()
    Dim ForLoopCounter As Integer
    For ForLoopCounter = 0 To List1.ListCount - 1
      If List1.Selected(ForLoopCounter) = True Then
        Text1.Text = MyArray(ForLoopCounter + 1)
        Exit For
      End If
    Next ForLoopCounter
    End Sub


    Good Luck

    Re: ABOUT STRING READING FROM textfile

    You need to modify YOUR code to his, or HIS code to yours. Can't mix variable names. It just double-spaces lines, but you can put YOUR If string inside of the loop. (Hint)

    Here's two ways:

    Code:
    Option Explicit
    
    Private Sub Form_Load()
      Dim x As Integer, st As String, y As Integer
      Dim ff As Integer
      Dim strBuff As String
      Dim str() As String
      ff = FreeFile
      Open App.Path & "\to do.txt" For Input As #ff
        strBuff = Input(LOF(ff), ff)
      Close #ff
      ' ----------------- two ways to skin a cat --------------
      MsgBox "Lines = " & Len(strBuff) - Len(Replace(strBuff, vbCrLf, "x")) + 1
      ' -------------------------------------------------------
      str() = Split(strBuff, vbCrLf)
      MsgBox "There are " & UBound(str) + 1 & " lines in the file"
      Dim words() As String
      For x = 0 To UBound(str)
        words = Split(str(x)) ' Split into WORDS
        For y = 0 To UBound(words)
          st = st & str(x) & vbCrLf & vbCrLf ' one line for each word
        Next y
      Next x
      MsgBox st
    End Sub

    Re: ABOUT STRING READING FROM textfile

    I thought you'd get that part. If you want to display three things at once, put them on the same line! Separate them with a character that won't be used. / , * ~ are usually OK

    Re: ABOUT STRING READING FROM textfile

    You have this:

    ALARM= ALARM1
    ZONE= ZONE6
    DESCRIPTION= NEED TO REPLACE

    ALARM= ALARM5
    ZONE= ZONE5
    DESCRIPTION= OK FOR 2 YEAR

    ALARM= ALARM9
    ZONE= ZONE7
    DESCRIPTION= NEED MAINTANENCE

    If it looked like THIS (first):

    ALARM= ALARM1/ZONE= ZONE6/DESCRIPTION= NEED TO REPLACE
    ALARM= ALARM5/ZONE= ZONE5/DESCRIPTION= OK FOR 2 YEAR
    ALARM= ALARM9/ZONE= ZONE7/DESCRIPTION= NEED MAINTANENCE
    It'd be easy to parse, but if you omit the labels, you'd have this:

    ALARM1/ZONE6/NEED TO REPLACE
    ALARM5/ZONE5/OK FOR 2 YEAR
    ALARM9/ZONE7/NEED MAINTANENCE
    Which is what it should look like. Just parse CrLf, then "/"

    Thanks for your info, it is not possible to change because the file is about 30MB, i am using to with VB.net/CSHARP , it is OK, but now i want to combine with some more useful source code in VB and that is why try to translate in VB6. If you interest , i can sent you this VB.net project.

    Re: ABOUT STRING READING FROM textfile

    I don't understand that. Use VB6 -or- VB.net and try again

    Re: ABOUT STRING READING FROM textfile

    I think I know, what you want. You want to store the additional info t an Alarm somewhere.
    Why not use a collection. You declare a collection for the additional data and then you load like this:
    Code:
    Private Dim MoreData as Collection
    Private Sub LoadFile(FileName As String)
      dim a$, b$, c$
      List1.Clear
      Set MoreData = New Collection
      Open FileName For Input As #1
      While Not EOF(1)
        Line Input #1, a$
        If InStr(a$, "ALARM=") Then
           List1.AddItem Trim(Mid$(a$, 7))
           Line Input #1, a$: b$=Trim(Mid$(a$,6))
           Line Input #1, a$: c$=Trim(mid$(a$,13))
           MoreData.Add b$ + "/" + c$
        End If
      Wend
      Close #1
    End Sub
    when an ALARM line is encountered, the Alarm is added to the listbox.
    Then 2 more lines are read in, the values concatenated with "/" and added to the collection.
    You have to watch out when retrieving the data, though. ListBox elements start with 0, Collections start with 1.
    That is, List1.Listitem(0) will contain "ALARM1", but the according data is in
    MoreData(1), which is "ZONE6/NEED TO REPLACE"

    Re: ABOUT STRING READING FROM textfile

    Thanks for your info, I think i havn't seen the code to load on the Textbox corresponding to listbox, is that code loading to listbox items?


    Anyway i have attach my sample BINARY(EXE) in .NET and sample data as well, so you will see exactly what the function look like.


    Many thanks

    Re: ABOUT STRING READING FROM textfile

    something you are doing :
    Code:
     Private Sub listBox1_MouseDoubleClick(ByVal sender As Object, ByVal e As MouseEventArgs)
                Dim num As Integer = Convert.ToInt32(Me.listBox1.SelectedIndex.ToString)
                Dim strArray As String() = File.ReadAllLines(".//data1.csv")
                Dim item As String = String.Empty
                Dim str2 As String
                For Each str2 In strArray
                    If ((str2.IndexOf("Package:") > -1) AndAlso (item.Length > 0)) Then
                        Me.entries.Add(item)
                        item = (str2 & ChrW(10))
                    Else
                        item = (item & str2 & ChrW(10))
                    End If
                Next
                Me.entries.Add(item)
                Me.richTextBox1.Text = Me.entries.Item(num)
            End Sub
    and it seems as if you're doing something else when a toolstrip is reached (but I did not see it in your exe) :

    Code:
    Process.Start("WGET\wget.exe", ("http://gb.archive.ubuntu.com/ubuntu/" & Me.textBox1.Text))
    Now, repeat : what are you looking for? Because even if I am amble to see the code you did not posted, I am not able to understand your needing
    ...at present time, using mainly Net 4.0, Vs 2010

    Re: ABOUT STRING READING FROM textfile

    Thanks for your reply , i already post complete code in VB.NET and at the top of forum when i start this thread, but people complain and i edit for that. The reason i post binary + sample is to undersatand people exactly what i mean. Even now i might need to delete this EXE as some people even private mail me and complain that this is not VB.NET forum.

    This reflector generate code is exactly the same as original code



    The only main thing i want is not when a toolstrip is reached , when mouse doubleclick, reading that csv data "BLOCK BY BLOCK to reach empty line of that block" and display on textbox, (that means not line counting , not ..........., data might contain 3 line, 4 line 100 lines in one BLOCK as like in the sample file i sent) , that is all i need .
    the other function i don't need that.



    Thanks
