VS 2008 Adding Records To A Textfile
Feb 7, 2010I am trying to add a player registration form to a textfile. And i have a few problems.One of these is that when adding to the textfile, it isnt recognising the selected value in a checkbox (checkbox is used to distinguish between a goalkeeper and an outfield player). Can you tell me what should I be writing to make this happen, - "chkGoalkeeper.??? = "" "

View 3 RepliesVisual Basic 2008: Reading From Textfile Into Array And Then Presented In Listbox?
Jan 7, 2012I've got the following txt file:
[code]...
Now I want that presented in the listbox with the semicolon and it should be aligned per column so that the numbers, the names, the prices and the quantity are exactly aligned per column.If I read the file like this:
[code]...
Then the semicolon is not presented in the listbox and I don't have any alignment per column. As the names of the woods are not equally long the prices and the quantity are not aligned directly below each other...
My questions are:
1) How to add the semicolon in the listbox as seperator of the columns
2) How to align the 4 columns in the listbox (as I have an array Item(3) )
Later on I need to be able to change the quantity (last column) from 0 to > 0 (that's why I have to use an array)
Store A Textfile (approx 6-30 KB) In A Variable?

View 3 RepliesHow To Read From TextFile And Store Data To Modify Later
Sep 2, 2011What I am trying to do may be better for use with SQL Server but I have seen many applications in the past that simply work on text files and I am wanting to try to imitate the same behaviour that those applications follow. I have a list of URL's in a text file. This is simple enough to open and read line by line, but how can I store additional data from the file and query the data?
E.g.
Text File:
link1 - 0
link2 - 0
link3 - 1
link4 - 0
link5 - 1
Then I will read the data with:
Private Sub ButtonX2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonX2.Click
OpenFileDialog1.Filter = "*txt Text Files|*.txt"
If OpenFileDialog1.ShowDialog() = DialogResult.OK Then
Dim AllText As String = My.Computer.FileSystem.ReadAllText(OpenFileDialog1.FileName)
Dim Lines() = Split(AllText, vbCrLf)
[Code] .....
Am I going completely the wrong way about storing the data after importing from a text file?

Nov 28, 2010I've got a csv text file "test.txt" in the following format with one record per line in the following format: Builder,Bob,B,99HappyStreet,Springtime,4
I've read them into an array and in design use the first two to populate a listbox and then use a selected index to fill text boxes and some list boxes.
ex. TextBox_FirstName.Text = Employees(ListBoxMain.SelectedIndex).FirstName
How do I write the changes made in the text fields back to the position in the file where it was? It has me stumped although I'm sure there is a SelectedIndex option that can work.
I've considered having all the new/changed data saved as a new record and then just deleting the 'old' entry but my delete code gives me a selectedindex-1 index out of range exception error that I'm working on as well. I am sure both problems are related.[cod]e...
