Add the items from text file into TextBox and ListBox.[code]...
Where, ";" is the Delimiter and data is just one line only. "A" has to load in TextBox and "Cat,.....,Bird" has to load in ListBox, one line per animal.I've already read the text file and load "A" into text box. But couldn't figure out how to load rest of the data into list box.
I have a text file in which there is a list which is composed as follows:
3236, Alberto
5894, Peter
7894: Alonso
and so on ...
What I want is loaded into a listbox the numbers to the first semicolon and load the combobox names.
i want to load a text file to my listbox. Chosen using a openfiledialog, so it wont have to be on a fixed location. However, i dont know how to do this. I know how to save a text file from a listbox, but not how to load one into it.
Next question, When loaded into the listbox, how can you select the next line?
I am trying to load a listbox from a text file, I have debugged the routine and have used the "step into", I have the routine in the Form Load section, it shows the names being loaded but will not show in the listbox itself, please please give me some ideas I have been racking my brain for days on this,

i'm trying to load a sequential text file into a listbox, and for some reason it won't move onto the next line? instead i get square characters instead
It appears like:
Where the square characters are, i want it to be an extra line as opposed to just that? here's the
Dim YOUREFILE As String = "C:Documents and SettingsAdministratorMy DocumentsPROJECTFILESYOURSTUDENTSCORES.TXT"
Dim objReader As New System.IO.StreamReader(YOUREFILE)

Here's what the file looks like:
I would like to know if there is a quicker way to load a text file into a listbox/arraylist than this:
Code:
Dim fileList as New ArrayList
Dim fileReader As New System.IO.StreamReader("textfile.txt")
Do While fileReader.Peek() <> -1
[Code].....
If I need to load several text files into different arraylists, especially if the textfiles have a lot of lines, this process is very slow. Too slow for my current app to work smoothly, actually.
So, is there any faster ways to load a text file into an arraylist? Or if there isn't, is there some quick way to easily access and change data that is on a particular line in a textbox, so that I don't have to load the text file into an arraylist?
I am trying to load the text file to the ListBox Object. But it doesn't work.
' Initialize an instance of the StreamReader object and declare variables

im having a issue where not all the data from my dgv is being loaded into text boxes on a 2nd form. What im doing is using the "DataGridView1.CellDoubleClick" event to open another form and pass the selected row into seperate columns, this works great but as i added more columns to the DGV it seems that the form is loading and not all the data is loading into the text boxes. Is there a way to halt the opening of the 2nd form until the loading is complete? i tried to simple "sleep" at the end right before the form is made visible but that didnt work. heres the code im using to load the DGV into text boxes, there are 16 columns, this is just the first one:
Code:
Edit.Item.Text = DataGridView1.Item(1, i).Value
as i said before, 13 or so of the 16 work fine, its the last few that refuse to load

View 14 RepliesI need to write data from a list box to an lsv text file. I can do that if I rea an entire line at a time and write it out, but the data in the listbox are columnated.For example:Cey,Ron 50 75 75 66.67would be an entire line from the listbox. It was entered into the listbox by reading an lsv text file and using format string to set up column info, but I don't know how to read it back out by column, only by entire line.

In my program i have a listbox populated with data from a sequential text file. [code] Mary, Murphy, 16, 893782, Douglas etc.From here the user selects the person they wish to see displayed in the datagrid with all all other relevant details from the text file displaying. Problem is I cannot figure out how to refer to the selected person and then get it displaying on its own in the datagrid. [code]

I'm studying VB 2010 at uni and struggling with this assignment, I'm stressing now with one week to go before its time to hand it in and still not knowing how to do it (even though i've read the whole textbook!)
I have copied the instructions and the files I have been given.
1 List all of the data from Teams.txt in a Listbox. Include suitable headings.
2 List all of the data from Results.txt in the Listbox (use the same Listbox as in 1 above). Include suitable headings. Note that you cannot assume that the file contains only results for the first 3 weeks of the season. Your program should be able to process a results file with more or fewer results.
3 List all of the data from Results.txt in the Listbox. However, in this case the actual team names should be output (your program will need to get this data from Teams.txt. The data should be formatted so that it is aligned correctly. Include suitable headings.
I have a rich text box which I use in order the user is able to add pictures, coloured writing, different font etc... however I need to load specific text in the rich text box when the user load the Form.how I can add (I guess) the HTML to load this every time the user load the form.
P.S the text will change depending on who loads the form so I can not do a simple
