Display Entries From A Csv Text File Individually In A Listb?
Mar 3, 2011
I made an application that writes to a text file in csv format, and on another tab, there is a listbox where the user can click the "View Report" button and it will display the information from the text file in a list box. Right now, I am really pleased with it because I was able to use "split" to get all of the separated values on there own individual lines.Now I am wondering, is there a way that I can display one entry at a time in the list box, and then maybe implement "previous entry" and "next entry" buttons so that the user doesn't have to scroll down through the entries to view them, they can just hit next entry and it will go to the next line in the csv text file and display the information from there? I have tried doing it a few different ways, here is what I have so far for the "View Current Report" button:
Private Sub btnViewCurrent_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnViewCurrent.Click
lblReport.Text = "Current Report"
[code].....

VB 2008
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
'Dim Reader As New StreamReader(Application.StartupPath + "/pbucon.log")
'TextBox1.Clear()
Dim Reader As New StreamReader("C:/Documents and Settings/Dorinda/Desktop/pbucon/pbucon.log")
Dim Line As String = Reader.ReadLine()
[Code] .....
I am trying to parse a log file and only display new entries containing the word "say". I have this set on a button click event, but I prefer a timer or something, but the textbox flashes everytime the timer ticks so I am using a button right now..

I am trying to access a txt flie in my project. This file contains many records that I wish to retrieve individually to make further calculations with.My first problem is how to connect to the file in my project, I have no clue howw to do this, have tried many different ways, but still no success.I also wist to have a textbox that I can type the (airport name) so that the streamreader will search for that record, similar to a google type search.

The following solution should allow the user to enter 'colors' to a combo box; however, if the color is already entered (in an upper, lower case or mixed case format), then the 'Duplicate Color' message should be displayed. I get the message, but my color is also being converted to an upper case format in the combo box.

Hi, i'm trying to use the treeview to display the text of a rtf (rich text file) file when an specific node if clicked.HomeOMGWOOTFor example, if i pick OMG, i want the text of lol.rtf to be displayed on a richtextbox. But somehow i just can't manage to get it... I know to import the text of a .txt file to a textbox, but using the treeview makes it more complicated.This is the code im using right now:
Private Sub TreeView1_NodeMouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.TreeNodeMouseClickEventArgs) Handles TreeView1.NodeMouseClick
Select Case e.Node.Index
Case 0
[code]....
Another thing is, that i can't import the *.rtf text into a richtextbox and i don't know why.

I have a program where you have three entries, CD name, artist, price and it goes into a listbox and .txt file when closing. I have to have a message box if you enter the same CD name. I have a code to open the .txt file and compare strings but I need to change it to compare only the CD name and not all three entries. Is there a way to do my string compare against my listbox without opening the .txt file?? The program loads the listbox from the .txt file when opening. Private Sub btnAdd_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnAdd.Click' adds CD information to the list box
' declare variables
Dim strName As String
Dim strArtist As String
Dim strPrice As String

I want to set a certain column to true or false automatically based on what value another column has entered. I managed to get this working by myself using the 'SQL Pane' in VB and testing it by using execute sql but I don't know what to do now. I assumed that I could just save it and it would work from there but that's not the case, it dissapears from the SQL Pane if I close the project (even though it worked fine when I ran the project the first time), so where do I put it/what do I do with it in order to get this to work?

I have a label that is supposed to display a word for 5 seconds and then move down the list in a text file and display the next word.I'm oddly able to make it work in random mode, but not going down the list in order.. random would be ok if used words didn't come up again.
Code:
Dim DurHold As String = My.Computer.FileSystem.ReadAllText(Application.StartupPath & "FlashWords.txt")
Dim DurDelimiters() As String = {vbNewLine}
Dim DurTextLines() As String = DurHold.Split(DurDelimiters, StringSplitOptions.RemoveEmptyEntries)

how to do this for vb6 however i am using vb 2008 and the code for vb6 does not seem to work.
I have designed a form with a text box on it, and a command button underneath. The idea is to run this as a sort of stiky notes section.
I want the text box to read rich text into the textbox (C:\\stickynotes.rtf")
Then i have a command button underneath which i want to save the content of the rich text box to the rtf file (C:\\stickynotes.rtf). This is so that the user can edit and ammend information.
here is some code i have so far
Dim fileReader As System.IO.StreamReader
fileReader = My.Computer.FileSystem.OpenTextFileReader("C:\\stickynotes.rtf")

I'm building a small program and I have a numbers only textbox where its content need to be higher than 1. So what I have is a messagebox pop when the text change and its lower or equal to 0. What I'd like to do is have the text changed to what it was before the number was changed to <= 0.Here's what I have for the control:
Private Sub txtDelay_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles txtDelay.TextChanged
If txtDelay.Text <= "0" Then
MessageBox.Show("Delay must be atleast 1 millisecond.", "Delay Error")
End If
End Sub

I have two text files, the first text file has two columns separated by a space (" ") and the second text file only has one column.
The column 1 in text file 1 and text file 2 match albeit in different order, what I'm trying to achieve is for every field in column 1 text file 2 I want to search for column 1 in text file 1 and display the matching column 2 field in column 2 text file 2.
Dim*OpenTextFile*As*String*= IO.Path.Combine("C:Test1.txt")
Dim*OpenTextFile2*As*String*= IO.Path.Combine("C:Test2.txt")
Dim*SaveTextFile*As*String*= IO.Path.Combine("C:Test2.txt")

am trying trying to write some code for a ComboBox that does the following:
1. Allow the user to enter text into the combo box to type entries contained in the list source.
2. Enable autocomplete to assist the user in selecting entries in the list source, both from dropped down state and non dropped down state.
3. Restrict the user from typing an entry that doesn't exist in the list source.
My requirements are:
1. The ComboBox must run some code after a selection has been made or the user has finished typing an entry (not after the focus has been moved to another control)
2. The code must only run once after the user has made a selection from the combobox or has finished typing an entry
The problem: To achieve the above functionality, I had to run code on numerous event's. Sureley there is a better way, here are the events and the reason for the code:
SelectedIndexChanged:This is the code that is run when the user makes a selection. No Mystery here
KeyDown:
Must Run
If e.KeyCode = Keys.Return Then
ComboBox1_SelectedIndexChanged(Nothing, Nothing)
End If
