Writing Info To And Getting Info From .text File Using A ListBox's Display

Jul 31, 2010

I am working on a media player, and I would like to setup a local playlist feature. I am using a single ListBox and its "Display-" and "Value-Member" properties. The display is the song's Artist and Name, and the value is the song's file path (i.e 'C:UsersUSERMusicetc.').To write the file path to the .txt file, I believe I can use the following code:[code]

Read Info From Text File And Add To ListBox

Jul 23, 2010

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
[Code] .....

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.

File I/O And Registry :: Using The SaveFileDialog To Save Listbox Info Into A Text File?

Mar 17, 2010

I'm using the SaveFileDialog to save listbox info into a text file. The files save fine, but when you go to save the file, if you hit the cancel button, it will overwrite the previous file you saved, because it's name was the same and it seems to save the previous file as the new name for your next file. Is there any way to catch if the user clicks cancel, and then exiting the sub if they did?

Aug 19, 2009

where can I find information on how to take info from a text box and save it to a file and later retrieve the info and print it out on a printer or back into text boxes? Also creating a database.Example. The Database will contain a list of customers. Within each customer profile there could be any number of databases for just that customer. and with in each database there is a system to keep track of different things.

Main Database = List of different Customers

Customer Data Base = List of different key systems.

Customer database key systems = list of key generated and if the have used that number or not. (Along with other info)

Bank App - Sorting Info In Text File

Mar 4, 2010

I am doing an assignment for my intermediate programming class. It is due tonight at 730. Anyways, I am almost finished, but I have run into a snag. I have this "bank application" and we are storing the info in a text file. However, whenever there is a deposit or withdrawal, the "accounts.txt" file is to be updated. All of the new account info is being written to a "Temp.txt" file and eventually will be renamed to the new "Accounts.txt" file. The problem I'm having is that it isn't writing non-updated account info to the temp file and I don't know how to make it do that while keeping the accounts in order and not rewriting the same account info more than once.

Here is the code for the entire project so far:
Imports System.IO
Public Class Form1
Private Sub btnProcess_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnProcess.Click
lstDisplay.Items.Clear()
[Code] .....

Open A Text File That Was Already Generated With Info Inside?

Nov 2, 2010

I'm trying to open a text file that was already generated with info inside.I want to read specific lines and have them changed via user input.the lines are not consistently on the same "line".An example of the text I'm trying to read and change is:

// General (upgradeable) values the Player sees for each system
hullLevel = 1700
weaponsLevel = 1450

[code]....

The "H" in hullLevel shows up in line 26 in some of the files, line 27 in other, line 36 in some others and line 37 in yet others.

The reason this jumps around is that this comes from a file that is edited by other modders when they create a ship for a game that I'm modding.My program is designed to allow the user to visually see a representation of how strong and well equiped a ship is and change the values of each line with a slider bar.I have all the slider bar and progress bar code worked out.

I just need a way to reliably pull these lines no matter where they are from the ship file chosen by the user so that the program can edit them without disturbing the rest of the text in the file.

Load Up A Text File Which Has Employee Info Separated With Commas?

Apr 13, 2009

I'm new to Comma Delimited values. What I'm trying to do is load up a text file which has employee info separated with commas

like 1/1/09, John Smith, (555) 555-5555, 101 S 1st Street and has numerous rows of info like this

so what I want it to do is just write this info to 4 different textboxes

like txtdate would just have all the dates of employees listed in rows or multilines

then another text box for names and so on.. Right now I just have it all being written to one text box.

I'm not sure how to separate all the information accordingly.
