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] .....

I am working on making a program that will log into my internet banking site (this will most likely have to be done in IE) grab my current available balance and store this to a string, before I do any research I was wondering if anybody had anything like this already completed.I also need it to do this silently (as in no open IE windows) no visibility of program running to the user.

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]

Ok so I know that you can sort by using a bunch of different sorting algorithms but I just am not sure how to start this off. I have written this code and just want to know if you can even sort this.
The program takes the users information in from text boxes from another part of the program and writes the information into a text file. So when the user clicks on this button it will display all the people that have entered in their names. I want to sort their last names alphabetticaly.
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnListCustomers.Click

I know similiar question have been asked but they are a little different so here I go. Basically I have a game in which the user enters their name and they get a score. This name and score then get recorded when they end the game as follows:
Dim userdataSW As New StreamWriter("E:GameScores.txt", True)
strline = frmVictory.TempPlayerName & "," & frmVictory.TempPlayerScore
userdataSW.WriteLine(strline)
userdataSW.Close()
userdataSW.Dispose()
What I then need to do is sort these values in the text file from largest to smallest (based on the number not the name but I still want the name to be assosiated with that score) so I can have the top 10 scores appear in a hall of fame type thing.

I have been trying to create an application that will read in the contents of a text file, sort the contents, add together any similar Client-Matter codes (based on the first two field values) and then create a new text file with the summarized results. [code]The first two fields can be treated as one field for sorting purposes. The two 403049,000017 lines would add together the last field, and use the most recent date in the newly created file.For some reason, I can not get the new file with the results created. I added messageboxes throughout the code to see where I am going wrong - they tell me where the program is going. They seem to point to me that everything is working but still, no export file.[code]

I'm using Visual Basic Express 2008 and I need to upload and sort two data text files (notepad) in a listview box. It doesn't have to be a listview box I chose that because it has nice options for columns. Anyway I've got the code set up to open the dialog box and allow the upload of multiple files. I've also got it set up to show separate columns, movie titles and box office amounts, titles in one file box office amount in the other. What I nee sorting the data once it's uploaded so the movie titles show in one column and the box office amounts show in another. Currently everything is showing in the left most column. I'd like to be able to represent the data seperately also so I can format the dollar amounts into currency. Here's what I've got so far:
Private Sub LoadButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles LoadButton.Click
Dim DialogBoxResults As System.Windows.Forms.OpenFileDialog

If Not FileContents(Y).Trim = "" Then

But this does not sorting anything. What is the wrong in the above code. And if i want to sort in decending order how to modify the code?

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?

I'm using VB 2008 express edition.I have to show the growth of savings in a bank account using input from two text boxes that will be deposit amount and interest rate. I have attached a picture of my form.I have declared my variables and now I'm working on my processing.When the compute button is hit, based on the deposit amount and the interest rate, the amount of years it takes to double the money and the amount of years it takes to become a millionaire with that amount will be displayed in the lower text boxes.
Here's some of my math reasoning...
Doubling time formula : 2P = P(1+ i)^n I tried solving for ^n and got: n = logP(1 + i)/log2P
Is this correct? How do I express logarithms in VB?As for the amount of years that it takes to become a millionaire, can I simply take the deposit amount for example $500 dollars and divide 1,000,000 by 500 to get 2000 so it takes 2000 deposits of 500 dollars each to reach 1 million. Is my arithmetic correct?

I've this txt file (almost 60 MiB)

Every line starts with 56000 then the first key, the the second key and the rest of the line. I tried to use SORT, that's included with Windows. It does a pretty nice job, but i need to have my own function in case SORT is not available. The output should write 560001002001 at first.

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)
Where is a good place to start.
Basic File saving to complex file saving.

I have managed to access and read a specific file line by line. If I wanted to split information by a comma or space and then sort alphabetically or numerically, how would I go about this procedure? Would I create a loop within the reading loop to parse the information?
Dim file As String = "C:Users est.txt"
Dim Line As String
If System.IO.File.Exists(file) = True Then

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.

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.

I am writing a program that lets someone click on a picture to vote for their favorite pet. The part I am stuck at is: when the application is opened and closed it needs to remember how many votes there were. To do so, when the program is closed I have the information stored in a .txt file. it looks something to the effect of:
name, type, votes
andy, bear, 0
bart, dog, 0
candy, cat, 0
hopsie, bunny, 0

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.

Okay so I am very new to visual basic I am currently using VB 2010 I know that this is not the correct forum but I figured it was the closest to it since there is no VB 2010.Anyways I am making a program for my Dad's company that can keep track of inventory so I need to store the info in a .txt and load it up etc. I currently am using a stream writer to write to the text and I got that down pat I am just having troubles loading it back up and putting the info in specific text boxes aka sorting or parsing? the information. I have looked at several tutorials and the problem is that I just simply don't know what I am looking at I've been tinkering with it for a couple hours now with no luck so I hope you guys could help me out .
Here is my current code. It is kind of useless because I have tried so many methods I thought maybe I could use a ReadAll function have it go to a string and parse from there hoping it would have been easier but it has not worked out for me so far.
[Code]...
^This above is just the output in test.txt and what will eventually need to get sorted into respective text/list boxes .

I am creating a banking system using excel and visual basic programming. To create a withdrawal macro I must have a button which will perform the following things: Ask the user via input box the account number, amount and pin. The program should then search for the relevant record in the account sheet, check the pin and reduce the balance by the correct amount. a message box should then result that tells the user they have made a successful withdrawal the program should not allow a withdrawal if this makes the corresponding balance less than - 1000
