Listview: Displaying From A Text File?
May 5, 2009
on my application i have a username and password form that saves the username & password It's not meant to be secure, and it writes to a text file displaying as so
Johnson:password1
Newname:password2
Newname2:password3
here is the code
Private Sub cmdPostAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdPostAdd.Click
'Add new username and password
[code]....
This all works fine, but i have no idea how to reload this information when the form loads.Obviously it needs to read the string, the seperate the username and password.also is it possible to password char the password section in the listview? at the moment it can be read.

I've been writing a weight program for flooded pressure vessels and I'm having trouble retrieving the data from the text files I've been saving. I know how to write the data to the text file, but retrieving it with OpenFileDialog is not so easy for me.The user has individual text boxes that they input strings or numbers into and when they save the file, each text box input is written to one line in the text file. For example, the first text box is for the username, therefore the first line of text that is saved is the person's name, the second text box is the customer, thus the second line in the text file is the customer name, and so on.
(Actually, the first line of text in the saved file designates whether English units were used or Metric units because when the user retrieves the saved file, English units will open one form and Metric units will open a separate form, so some If...Then statement will need to occur).I need to be able to read the first line, have either my "EnglishForm"form open or my "MetricForm" form open, and then have each subsequent line of text be displayed in their corresponding text boxes. I know I need to use ReadLine or LineInput, but I don't have a clue what to do.Assuming the syntax I've displayed below would just magically work (if only life were that easy), it would look something like this
If FirstLineOfTextInFile = "English" Then
EnglishForm.Show()
ElseIf FirstLineOfTextInFile = "Metric" Then[code]....
And so on...I read a lot of articles from the MSDN library and exhausted each link that I've looked through from Google and Bing, but most only retrieve data from the file to a single text box through some loop or streamreader and don't take into account multiple forms.

I have the following code that displays the last line of my text file:
VB
Private Sub btnCurrent_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCurrent.Click
Dim path As String = "C:Documents and SettingsTwiLiteDesktopWindows Programming - Laura Malave/MadEaters SolutionMadEatersSurvey.txt"
Dim readText() As String = File.ReadAllLines(path)
Dim s As String
For Each s In readText
lblResults.Text = s
Next
End Sub
How I can display the last 12 lines of code instead of just the last line.

Different weapons can be gathered which consume hearts when used, these hearts can also be collected from monsters and candles. Additionally, some walls will hide secrets such as the health-restorative turkey or the Double and Triple shot abilities for the weapons Simon has collected.

I am loading a KJV.rtf file at program startup into RichTextBoxDisplay. When I want to select, lets say, Matthew Chapter 1, I want the program to take me to Matthew Chapter 1. I know I could just load a seperate file into the rtbDisplay, but do you know how many chapters and books are in the Bible..

I have been trying to load two text files into a listview all weekend, this one has me stumped. I have searched the web and my material but have been unable to make anything work or display the data in the listview.
I am trying to load two text files at the same time. I have figured out how to load the files but I cannot get the data to display. One file has 50 lines of numbers, which I want to display in column 1, and the other file contains 50 lines of letters, which I would like to display in column 2.
Once the data is loaded to the listview I will need to sort the columns by alphabetical order and numeric order. But I need to get the files to load and display first, this is the code I have come up with so far:
HTML
Private Sub ButtonLoadFiles_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonLoadFiles.Click
Dim myStream As Stream = Nothing

I have an application with a listview which contains 3 columns (account, password, and a hidden column).
I have written some code to save the contents of the account and password columns in the format Account|Password.
Now I would like to be able to import text files into the listview. I was thinking about reading the text file then splitting it using Split("|") however I don't know how to put the variables in the seperate columns. Here is my code:
Dim accounts As String
Dim i As Integer
Dim aryTextFile() As String

I have a question because in my I.O.File. I use this to save the data in the listview in a c: est.txt but the problem is that it only save one data and every time I click the save the previous data that I save is deleted and it change the new one that I save. And also when I click the remove in the listview it will also delete the data that save in the c: est.txt and the format should like this
First name | lastname | address |
rae alanah new york
john smith los angeles
Here the code that I did...
Dim myFile As String = "C: est.txt" '//file location
System.IO.File.WriteAllText(myFile, TextBox1.Text & " " & ComboBox1.Text & " " & TextBox4.Text & " " & ComboBox2.Text & " " & TextBox3.Text & " " & TextBox2.Text & " " & TextBox5.Text)
Or you can also create new code base on ur understanding. This is the first time I use the I.O file or file stream in vb.net because my crystal report does not detect my database that's why I need to do this.

I'm using Visual Basic Express 2008 and I need to upload and sort two data text files (notepad) in a listview box. It doesn't have to be a listview box I chose that because it has nice options for columns. Anyway I've got the code set up to open the dialog box and allow the upload of multiple files. I've also got it set up to show separate columns, movie titles and box office amounts, titles in one file box office amount in the other. What I nee sorting the data once it's uploaded so the movie titles show in one column and the box office amounts show in another. Currently everything is showing in the left most column. I'd like to be able to represent the data seperately also so I can format the dollar amounts into currency. Here's what I've got so far:
Private Sub LoadButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles LoadButton.Click
Dim DialogBoxResults As System.Windows.Forms.OpenFileDialog

I have a ListView capable of displaying files in all available views (Large Icon, Small Icon, Tile, List, Details). Now I am wondering how to properly use the SmallImagelist and LargeImagelist for the small and large icons...the ListView is actually a modified listview (inheriting from ListView), using a modified ListViewItemCollection.In this custom ListViewItemCollection I use the Add override function to add a few details to my ListViewItem:
vb.net Public Overrides Function Add(ByVal value As System.Windows.Forms.ListViewItem) As System.Windows.Forms.ListViewItem
Dim file As clsTexture = TryCast(value, clsTexture)
If file IsNot Nothing Then
[Code]...
I realize it is a pretty complex post to read and will probably not get very many answers, but I really want to make the most of my Listviews...Of course, one work around is to just always use the LargeIcon which then gets scaled down automatically when the SmallImagelist is used but I am pretty sure there are icons that are very different in Large or Small view...
