How To Write Listbox Data To Text File

Jun 8, 2010

I 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.

Write Listbox Text To Text File And Keep Columns Aligned?

Apr 16, 2011

I've got a program which displays data in a listbox in five columns. All are separated using one or more ControlChars.Tab. I want to write these columns to a text file, however, when I do, my columns lose their alignment. I can change alignment so that it displays nicely in text file, but then it is off in list box. Is there a way to get what I see in my listbox to display the same way in a text file - maybe a different way of separating my columns (not using ControlChars.Tab)?

Write To A Textfile From Listbox?

Aug 28, 2011

It may seem noobish but, I've been try forever! I've been postponing a database project for like 3 years and I finally come to some solutions except for when it deletes an Item from the list. On form load, the listbox generates data from a text file (we'll call text1) which has data in it. For every line of data in that text file (text1), there is a text file (text2) in a 2nd folder.

For example, there may be, in text1, a line named "Hi". In the 2nd folder there is a text file named "hi.txt" Another line (say the next line under 'Hi') is written as "Hello world", there will be a file in the second folder called hello world.txt"

May seem confusing but it works well. My problem is making that 1st text file that has ALL of the data that loads into the listbox, be rewritten over with the new data in the listbox OR remove a certain line of from the text file.

Write Some Code Which Parses Data And Then Populates A Listbox

Oct 24, 2009

I'm trying to write some code which parses data and then populates a listbox. I'm using the IPWorks IPPort component which basically does the reading of port 30003. The ipport1_OnDataIn event is where all the action is. I parse the data, which works great.. however when I try and do something simple such as add text to a listbox, I get the dreaded error "Cross-thread operation not valid: Control 'lstListBox1' accessed from a thread other than the thread it was created on".I've googled the error and tried copy and pasting some workarounds but nothing seems to fix the issue.

If anyone can offer help, it would be greatly appreciated. If you could possibly show the code already implemented into mine, it would be even better so I can see how it works. It would make more sense to me. My code is below. The part i'm trying to get working is the lstlistbox1.items.add("Test") in Case "2". This is to just get it working.. I'll be adding listbox items in the other cases as well, and they'll be parsed values instead of "Test". This is just to simplify things at the moment.

File I/O And Registry :: Write A Text File In XP Versus Win7

Sep 28, 2011

I am using Visual Studio 2008 on Windows XP SP3. User has Windows 7 Pro (32 bit). The IO code below works for me. The read code works for user, but the write code only works for new files. If the user tries to overwrite a current data file, then no data is written to disk. I have done all the usual IO checking (valid file name, etc.) and have excluded it from my same code. In my app, FileSave and FileSaveAs both call WriteDataFile(FullFileName). Any reasons why FIleSave would work on Windows XP, but not on Windows 7 Pro (32 bit)?

Code:
Public Function ReadDataFile(ByVal FullFileName As String) As Integer
' reads a Data file from disk
'
' Format is a text file, with [TAB] seperators and [CR][LF] as line terminators

C# - Load A File, Manipulate The Data, And Write A New File?

Mar 6, 2012

I have an issue where I need to load a fixed-length file. Process some of the fields, generate a few others, and finally output a new file. The difficult part is that the file is of part numbers and some of the products are superceded by other products (which can also be superceded). What I need to do is follow the superceded trail to get information I need to replace some of the fields in the row I am looking at. So how can I best handle about 200000 lines from a file and the need to move up and down within the given products? I thought about using a collection to hold the data or a dataset, but I just don't think this is the right way.[code]....

File I/O And Registry :: File Read/write From A Collection?

Nov 17, 2010

I am working on a program with multiple collections related to one another for a school project. Each collection needs to have its own defined properties and have the objects written (1 per line) to a text file.

I have all of that working.

When reading the comma-separated line from the file, I want to place one of the properties of the object in a listbox (so that all the objects' names will show up in the listbox). I think I have this part figured out...

My problem is that when you click on the name in the listbox, I would like multiple text boxes to be populated with the appropriate, corresponding properties of the particular object in the collection...is there a way for this to be done?
