I have a form with 2 listboxes. I have 1 item added in each listbox. When I save the file, it contains the items within each listbox, I use a separator in the saved text file to denote which listbox each string is from.
This is my save file dialog code:
As you can see, | is the separator that comes before listbox1 items and || is the separator that comes before listbox2 items in the saved text file. Now, what I want to do is open this file and distribute each string in the file to the appropriate listbox.
This is what the saved text file looks like:
This is my code for the open file dialog:
As you see, if the streamreader reads the line "|" (the listbox1 separator), then I have instructed the program to keep adding whatever the streamreader reads into listbox1 UNTIL the streamreader reads the line "||" (the listbox2 separator).
Now what happens when I open the file is that only the "asd" line is added into listbox1. The reader for some reason wont keep looping to the next line until it reads the listbox2 separator (||). I need it to add EVERYTHING into listbox1 until it reads ||. What do I do to fix this? Sorry, I know it's a lot of writing.
This is my save file dialog code:
VB.NET:
Private Sub SaveToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SaveToolStripMenuItem.Click
SaveFileDialog1.Filter = ".txt (*.txt)|*.txt"
If SaveFileDialog1.ShowDialog = Windows.Forms.DialogResult.OK Then
Using myWriter As New System.IO.StreamWriter(SaveFileDialog1.FileName)
myWriter.WriteLine("|")
For Each Item As String In ListBox1.Items
myWriter.WriteLine(Item)
Next
myWriter.WriteLine("||")
For Each Item As String In ListBox2.Items
myWriter.WriteLine(Item)
Next
End Using
End If
End Sub
