I found somethings and modified a bit the code so its can fit with what i needed.
I got it to work. Its read the text file but not i would like it to read.
In the ListBox, the text show up in 1 line as it should show in multi-line... (Yes, in the .txt file the text is in separated line.)[code]...
Let's say, when you click a button it just opens a specified .txt file and adds the data of it to a listbox. I mean automatically, without that file opening dialog showing?
View 1 RepliesI am writing an application that will use a OpenFileDialog control that will read a text file into memory and later process it.
I do have the following filter: Text files (*.txt)|*.txt|CSV files (*.csv)|*.csv|Spaced Text files (*.prn)|*.prn|All files (*.*)|*.*"
When I navigate to my test folder that contains a single .txt file, I see that file. When I change the filter to *.cvs that files goes disappears because it has a .txt extension. That is good. But when I select All files *.* it does not re appear? Why and how do I make it appear.
I am making a program, obviously, and I require some assistance. I found an explanation on how to read information from a Text file and have modified it for my needs. Here is my (modded) version:
Public Function GetInfo(ByVal playlistname As String) As String
On Error Resume Next
Dim PlaylistInfo As String
Dim ReadInfo As System.IO.StreamReader = System.IO.File.OpenText(My.Settings.OpenPlaylistName)
PlaylistInfo = ReadInfo.ReadToEnd

I pretty much understood how to write text to a file, but I cannot grasp how to READ the information. After I read the information, I would like to add each seperate line to a ListBox. Each line in the text file is a file path for a music file, as the file I wish to read information from is a "custom extension" playlist file. I know what to do after I get the file path, but I do not know how to get the file path from the playlist.
in resources there is a text file with items like number 1

View 13 RepliesI currently know how to click a button on the application and when I click it, it invokes the OpenFileDialog Event or Object. After It Opens the Open File Dialog, I am able to select only ONE file from a location on my computer. After I click that Single File on my computer, I press the Okay or Open Button on the Open File Dialog, and then it adds that items to my list Box, knows as PlayList_00 and PlayList_01.
Here's what I got so far.
Private Sub addBTN_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles addBTN.Click
OFD.InitialDirectory = "C:Movies"
OFD.ShowDialog()
PlayList_00.Items.Add(OFD.FileName)

The projects program is designed to open files output by another program, allow the user to edit the files content, then send the file to a specific bookmark within a word template. Unfortunately most of the output files by the 'other program' are html format.Question Is there a way to strip out HTML from the file when it has opened in my text area within the program? I found one or two online guides but haven't managed to get them working.

I'm trying to Load data from a Text file, which is "," Delimited into 6 List Boxes.. Want a FileOpenDialog Box so that the user Can chose which Office Id txt File they wont to load into the List Boxes.How it works is;
-The user Enters an Office ID (e.g HH33)
-The user fills out the rest of the program, the data is then generated into the 6 list Boxes
-User then clicks Save to File button.
-The program creates a Text file with the name coming from the Office Id, so if the user enters HH33, the text file is created with name HH33.txt.
-All Data entered by the user under the office name HH33 will be added to the Text File..[code]

I have code which saves DGV contents including check box columns as a comma separated text file. I also have correct code which will take the text file and re-insert it into the DGV at a later time. This all works.When I'm working on the DGV, I have this
Private Sub DataGridView1_CellValueChanged(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellValueChanged
If DataGridView1.Columns(e.ColumnIndex).Name = "Column12" Then[code]....
So that when the check box is true, columns 1 and 3 turn different colours, and when false, go to a yellow colour.However, when I "re-insert" my DGV info from my text file, the check boxes come back correctly - as true and false on the right rows - but columns 1 and 3 don't change colour. I've tried a "DataGridView1.Refresh" option but not getting it to work.The DGV is unbound. I need it to recognise which check boxes are true and update automatically when the information is opened from a text file.
I'm using vb.net 1.1 to develop the program. I got text files that contain test result from a machine, like below.
T1 1.24535 2.56335 2.43253 1.24538 2.55619 4.35243
T2 1.42542 1.63728 3.57295 4.59275 1.57320 2.72057
T3 5.12857 2.45375 6.38593 2.58375 3.57259 3.57204
I need to check the test result with the data from database, to find out which test result is failed. If there is a fail test result, I will show an alert to the operator and stop the checking process. Until the operator close the alert, then the checking process will continue from the last read point.
I am stuck on an easy problem I'm sure, but for the life of me i cannot figure it out. I need to read a sequential file into a listbox. I can read the file into the textbox but i want to format the data in the listbox. for example i want to PadLeft(10), delete the excess commas, and give a heading for each column. here is the code i have and attached is the text file.

I am starting to learn reading and writing to textfiles. One quick problem. My code here
'Read is the variable that will read the kp.txt file"
Dim read As IO.StreamReader
read = IO.File.OpenText("C:2/kp.txt"[code].....
however when it is read into the listbox those 3 words appear on one line in listbox
How can i make it so that each line of the textfile is placed in each line on the listbox?
my knowledge of VB.net is limited and i'm really trying hard to figure this problem out...
what i did was create a list box and populate it with a directory ("C:Documents and Settingsuserfolder1")...
once the listbox displays the files from the directory, i want to select a certain file and that file will be opened up in a rich text box.What i found to display the directory in a listbox is:
Dim directory As New IO.DirectoryInfo("C:Documents and SettingsjtanDesktopRECV")
Dim diar1 As IO.FileInfo() = directory.GetFiles()
Dim dra As IO.FileInfo
Dim files As String

View 7 RepliesI'm trying to get a random line of text to appear in a messagebox upon button click, I want the listbox to be closed while the action is to be performed.
I can do it when the listbox is open but not when closed, here is what happens if I try to do it when it's closed
and the message "InvalidArgument=Value of '0' is not valid for 'SelectedIndex'."
I tried reading it straight from the .xml file the data is stored on, but that didn't go so well either.
