I have a text file with an unknown number of lines. I want to read this file line by line and send each line's text in a check list box. But how am i gonna do that when i don't know how many lines exist in text the file? [code]The code above reads only the first line. I tried to do it as in vb6 using while not eof(but here i don't know what to write cause my file isn't opened in a certain channel).

I have code that reads the whole file, not line by line.
Here is the code:
FileOpen(1, filename, OpenMode.Input)
Do While Not EOF(1)
datatodisplay = LineInput(1)
Loop
FileClose(1)
I would like to know how I can read the file line by line and then add all results into an array list.

what i need to do is open a txt file, read line by line, decode each line into an array and display. Now all works ok apart from one line.
sTextLine = objReader.ReadLine() <-- Value of string cannot be converted.

Dim objReader As New System.IO.StreamReader(sOpenFile.Text)
Dim sTextLine As New ArrayList()
Dim sText As String = ""
Dim i As Integer = 0

Ok, I saw this code on the net
Dim sFileName As String
Dim srFileReader As System.IO.StreamReader
Dim sInputLine As String
sFileName = "D:UsersArbenDesktopSerieA.txt"
srFileReader = System.IO.File.OpenText(sFileName)
[Code]...
under the code I pasted at the top, but I get the text on line1 in all labels, like all labels become 1, while the text should be 1, 2, 3 and so on. So anyone can help me do that, each label gets the value of the next line in the txt file

I've never had to work with them before, and I think I've got everything down except one big thing: I'm setting it up so that different settings have different values depending on what file is being read. I need to know how to tell vb to take a specific item in an array and make the setting equal to it. I know how to make it read the file and add each new line into the array, just need to make sure I'll have to correct method to get the item in the array to match up the setting.

How do I read a line from a database using WHERE? I've read this post but it doesn't really cover it and the forum search throws out the words, 'From' and 'Where' as being common. This is my bit of code but it just skips over it as if it doesn't exist so presumably there's an error, I dunno. I'm trying to read an entire line from the database where it equals the value of 'getweek' where 'getweek' is a variable.

I'm trying to add a reference to the GAC version of System.Xml in a Visual Studio 2008 web site project. I right-click the project icon in the Solution Explorer, and click Property Pages. Under the References tree option, I click the 'Add' button on the right. I navigate to System.Xml in the .NET tab, and double click it (the Path it lists for System.Xml, C:WINDOWSMicrosoft.NETFrameworkv2.0.50727System.XML.dll, DOES exist). The dialog disappears, but... System.Xml does not get added as a reference! The list just stays the same.

I am trying to read a line from a file and add it into a listbox. The SelectedIndexChanged event of the listbox places the selected item (hence, the item I added from the file) into a variable that is declared as a Store (my own personal class.) I can easily add the line from the file into the listbox, but I run into a problem with the SelectedIndexChanged event. When I click on the item in the listbox, I get an error that says "Unable to cast object of type 'System.String' to type 'WindowsApplication1.Store'." (I guess this is because I added an item to the listbox that is from a file.) I tried a variety of methods of casting, but nothing seems to work. What can I do to fix this?
