VS 2008 Remove Blank Lines From Text File?
Oct 1, 2009
I have a text file that I'm reading into a listbox. I want to skip a line if it's blank. The following code works if I leave out the check for the line being blank. It puts the file in the listbox with no errors. However, when I include the If statement that checks for the line being blank, I get an ArgumentNullException in the Items.Add line when It gets to the end of the file.
'Read Multiline File
Dim FILE_NAME As String = "C: empliz-etsy.txt"

I use the following coding to replace a word in my textfile, would it be possible to add any coding that will remove all blank lines from the same text file?
Dim EditMyFile As String = IO.Path.Combine("D:Test.txt")
Dim inputFile = Regex.Replace(IO.File.ReadAllText(EditMyFile), "test", "test2")
IO.File.WriteAllText(EditMyFile, inputFile)
I have tried the following but it doesnt work.
Dim EditMyFile As String = IO.Path.Combine("D:Test.txt")
Dim inputFile = Regex.Replace(IO.File.ReadAllText(EditMyFile), "test", "test2")
IO.File.WriteAllText(EditMyFile, inputFile)
Dim sText As String = File.ReadAllText("D:Test.txt")
Dim sNewLines() As String = sText.Split(New Char() {ControlChars.Lf}, StringSplitOptions.RemoveEmptyEntries)
File.WriteAllLines("D:Test.txt", sNewLines)

This combo box is databound to a SQL backend, so when it is filled it has a blank at the top of the list. I am assuming this is added because of the NULL at the bottom of the SQL table. Is there a way to remove this entry?
I have tried the following:
.items.remove("") ' does not work, i added this after the population command
.items.removeAt(0) ' This gave me an exception stating that it could not be used because the datasource was used This is the code i use to fill the combobox on form load:
With ManufacturerComboBox
.DisplayMember = "Manufacturer"
.ValueMember = "ManufacturerID"

I need to go line by line through a text file as well as a listbox and remove lines over x amount of characters as well as adding the number of skipped lines to a label. I am trying to use a listbox in this example but it is not working correctly. What I am I doing wrong? First it will only remove an item when it is highlighted (focused) how can I make it so that is not required?[code]...
