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"

I'm currently making a program that will be used to practice German. It reads from textfiles that have English words (noted by # prefix) and German words (noted by $ prefix). An example of this:
#hello $hallo
#good $gut
#evening $abends
The way it currently works is it loads a text file, finds all # and splits to an array called "English" and finds all $ and splits it to an array called "German" What I want it to now do is feed the "English" entries into textboxes on the left, and "German" onto textboxes on the right so I can then match them out and make a sort of memory game out of it. Unfortunately, I don't know how I would loop an array through multiple textboxes. Conveniently, the textboxes on the left have even numbers, and the ones on the right have odd. Is there a way to possibly find all evenly numbered textboxes and loop "English" array entries into them, and the same for "German"? I've realised this has now gotten a little convoluted, but hopefully somebody understands. I can screenshot the form for better explanation, and copy my existing source code if anybody wants it.
I have this Quiz software that lets you create online multiple choice quizzes which are great for studying (I am in grad school and I'm trying to use everything I can to learn). So the Quiz software is great but it only lets you input questions by hand, one by one. I took a look at the .xml file that the quiz program spits out and came up with the idea to try and make a converter so that I can import many questions at once. I was hoping to try and solve this limitation by doing the following:
Take a .doc that say a tutor gives us with a bunch of practice questions, and then take that into Crimson Editor, and then format it so the question is on line 1, the multiple choice answers are on lines 3,4,5, and 6, (for the next question, the question would be on line 11, and the answers on lines 13, 14, 15, and 16, and so on) and then take that saved .txt file into my program, hit the generate button, and it will spit out the .xml file, and then import that into the quiz software to generate the online quiz.
Here is an attached screenshot of my program layout so far:
I figured out how to open a text file by watching simple youtube tutorials, but I don't know how to have it generate the stuff and have it show up in the bottom text box. I know how to do the coding to convert the txt to proper xml code but I don't know how to be able to save the contents of the bottom text window to an xml file.
I would like to sort out the repeating lines after reading the text file.
For example i would like to sort:
VERSION 600
LIBRARY [2009/6/15 15:02:14, 2009/6/15 15:02:14] temp.gds
UNITS 0.001 1e-009

How do i continue from here to sort the textfile to get what i want?

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.

I'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.
I am building a program to populate an Excel invoice template. The program works for the most part, except for one odd flaw. The program calls a module which first checks that two text boxes on a form have been completed. However, whilst the program does see when one of the text boxes has not been filled in (txtContact) it doesn't see the other (txtCustomer) even if I change the name of the text box to check it still only responds when the the other text box is empty.

I 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:
Basically, Im running an SQL query to the database, which obviously returns data in their fields. What I want to do is add each record into an ArrayList and split the string based on fields. I.E
CustomerID,Surname,GivenName etc
How do I go about this? so far I have:
alstData.AddRange(sLine.Split(","c))
sLine = the record from the database.
This doesnt seem to work, it just display's the data in one line with no split such as 20205SmithJohn?
I have a txt file, that i want to read into my program. The problem is this:The textfile is a stats file for a game and looks like this:
Code:
ip:port wins username points
ip:port wins username points
ip:port wins username points
ip:port wins username points
ip:port wins username points
etc.
The main thing i want to do is sort these things out and then add to mysql database table that would have these columns:
Code:
ip authid wins username points
So what i wanna do is splitting this textfile data up and then adding everything to a mysql table.

I am trying to read the file contents using
System.IO.File.ReadAllText
After reading the file contents the special charaters gets replaced with some garbage characters like "?".
To eliminate this I have used encoding along with above method

But still it is not working.
splitting and trimming text file
View 1 RepliesI've got a problem reading in a Tab-Delimited text file. There's an extra tab in one of the fields its reading it thats not a delimiter, and it's throwing off me reading the file into a table. This specific file does have quotations around that field though.
What would be the best way to take that tab out before splitting the row by vbTab?
Im reading each line in the text field like this, splitting on vbTab. X is a string array
text = x(J).Split(vbTab)
I have I text tab delimited file. in every line of that file at the same position in every row of the file I will have a bit that I would want to compare against 23 values (I will call them criteria). So if on every row the string I need matches one of tjhese values then that row will be written in File1.Txt if that value doesn`t match any of the criteria the whole row will be sent to File2.txt.
So far managed to get the original file written in the same format in a newly created file.
how to get the functionality I described working but am stuck with correct syntax.
Here is what I have so far:
Dim fs As New FileStream("C:Original.txt", FileMode.Open, FileAccess.Read)
RichTextBox1.Text = ""
Dim d As New StreamReader(fs)
[Code]....
Now I will need to declare every single row in RichTextBox1 as String then will have to get the bit I need will have to declare that as well(I will need from every row the string taht is between characters 96 and 104), also where do I keep the 23 criteraia values.
I am exporting a directory list from a FTP directory to a text file, I would like any suggestions how best to read and split the information detailed on each row in the text file as information isn't Tab Delimited (which i have code for if it was) and the number of spaces between each attribute is different. Below is a snippet of the text file, the main two I require is the File Size and the Filename.

View 1 RepliesI have a large tab delimited text file to process each day (usually around 25 mb) consisting of usually well over 100,000 lines. The file is actually made up of about 9 or 10 reports separated by "END OF REPORT". I'm wanting to write each individual report to it's own text file. Some values may have trailing spaces or even contain nothing but spaces, so I am wanting to trim those to only the data, or be left with null. Ultimately each report will be imported into sql server tables. The code I have below runs successfully to completionwithout error although each text file is empty.

if i replace the MsgBox code with Combobox1.text = (strArr(count)) i get nothing.
I have a delimited text file, let's call it models.txt and it's delimited by a comma with carriage returns.
example:

What I want to do is to display the right part of the delimited text (Z920081, Z920082, etc) in the combo box. But when you select the item in the combo box, I want it to use the left part of the delimited text (21, 22, 59, 120, etc) as a variable for other use.

View 1 RepliesOk 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.

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 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.

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 RepliesI'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:
