Copying Data A File Int An Existing File Where The Filename Of Both The Data File And Existing File Will Vary From User To User
Aug 5, 2011I have a workbook (Workbook1) that runs through some steps using visual basic, which ends up opening another workbook Workbook2). Once Workbook 2 is opened, I need to copy a section of data from it, into Workbook1 int a specific worksheet. I was able to do this by recording a macro, but the challange is, the name of Workbook 1, and Workbook 2, will vary by User. When I created the macro it uses the files as they are currently named.

Sorting A CSV File From Within An App
Mar 25, 2009I have a VB.Net 2005 application in which I access a SQL Server DB to pull data into a Dataset. Within my app, this dataset is read sequentially. Then, a cross reference file is read against the dataset record. If there is a match (based on 2 fields from the dataset record), a field value from the cross reference file is used to replace a certain value in the dataset record. Once a dataset record has been read and processed...it is written to a new CSV file. This CSV file contains 5 columns.
I've been requested to now sort this new CSV file using 3 of the 5 columns as the "Sort Key". What would be the fastest way to do this?
I know one way would be to create a new dataset and insert the finished record into this new dataset in the order of the 3 fields (which I'm not sure how to setup).
Excel Sorting Is Only Sorting One Column Not Multiple?

Wpf - Sorting Observable Collection Incorrectly Sorting?
Aug 20, 2011I have a WPF ObservableCollection which is bound to a ListBox and I have a Sort() method which when called will convert the ObservableCollection to a List(Of T), and undertakes a sort based on a date/time column within the collection.
The data is sorted, even when new items are added to the ObservableCollection, however the date/time isn't being correctly sorted. The data is sorting based on the date however it is very much random when it comes to the time portion. The following is an example of the outcomes I am experiencing:

Is there anything that I am doing incorrectly in this method that would cause the time portion not be included in the sort? Is there a better way of doing a sort?
Reading And Sorting A .CSV File?
Feb 3, 2009I'm a relative novice when it comes to object oriented programming..
How can I use VB.net to efficiently read a large .CSV file, store the records (rows) in a table (an Object or an Array), and then sort them using multiple keys? (e.g. sort by Last Name and First Name) After some additional processing, the output will be written to another .CSV file.
Sorting Accounts In A .txt File?
Jun 21, 2011I'm trying to make a simple program that stores my accounts in a .txt file. Each account has 3 properties, account, password, and source. I know there are alot of better ways to do this, but I'd really rather use a text file because I'm working with PhP also.
testacc1 password1 source1
testacc2 password2 source2
testacc3 password3 source3
I can easily write this to a .txt file, but how can I go through it?

Feb 18, 2010I'm using Visual Studio .Net 2008 on Vista. The goal of my program is to watch a directory, get file information, then sort them by thier date, and produce a updated text file. I can't seem to get my code to generate a list of files sorted by date. The code does produce a general list of files, however presently ordered in the directory. I also tried an alternate way of sorting the files by date by creating a string, removing the date using substring, then comparing the file dates using datetime.parse but it produces a exception error.

Reading, Reformating, And Sorting An .XLS File?
Aug 21, 2009I have a spreadsheet in .XLS format that contains more than 60,000 rows with 12 columns per row. The first column contains the person's name (Last First Middle), which needs to be split into three columns by pushing columns 2 - 12 over into 4 - 14 and making 1, 2, and 3 the Last, First, and Middle Name columns. Then the file needs to be sorted by those three name fields and match-merged against the results of a SQL query (4,000+ records), which is being generated within the VB.net program.
Using VB.net, I can read the .XLS file, parse out the Name, and save the 14 columns into a 2-dimensional Object array. But I can't figure out how to sort it because 'Array.Sort(spreadsheet_table)' will only work on a 1-dimensional table. Maybe I shouldn't be using an Object, but I'm inexperienced enough that I couldn't get DataTable to work.
I'm writing the program as a "Console Application" using Visual Basic (VB.net) 2008 Express Edition in a Windows XP SP3 environment. The following is an example of the input data:
Sorting A Text File In VB 2008?
May 4, 2009Ok 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.

Sorting Values In A Text File?
Jun 6, 2012I 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.

Bank App - Sorting Info In Text File
Mar 4, 2010I 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()

Sorting And Summarizing Text File Data
Apr 15, 2009I 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]
View 1 RepliesSorting Data From .text File In Listview?
Mar 9, 2012I'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:

Staff members can also use the "add an employee" function to add a new employee to the Random File.The problem is, everytime i try to create a new employee and hit the save button, the new record writes over the existing records, one by one, everytime the programme is stopped and started up again.
My Question is: How can i get the new record to be saved, without deleting existing records,
Here is the save buttons click method:FileOpen(fileNumber, "C:employee.dat", OpenMode.Random, OpenAccess.Write) 'open the file with Write Access
myEmployee.name = txtNewName.Text 'adds the name
myEmployee.id = txtNewID.Text 'adds the ID
