Reading / Parsing / Writing A Text File?
Oct 7, 2009I'm using visual basic 2008 express to do some simple stuff. For this project, Im reading in one large text file.The top of each page has a header section that is always the same, except sometimes a dept# changes, signifying a new set of data.The first line always has the text "RunDate", so when I read that, I know that I'm at the top of the first page.After reading the first line, I'd like to immediately go to the sixth line and grab that dept# and store it.dept = left(trim(myline,7)(Its always 7 characters long) so I know what dept I'm working on.I'll then loop through and write each line to a new text file, until I hit the top of a new page.At that point I need to look at line 6 again. if the dept # is the same, I'll keep writing to the same file.Reading and re-writing from the text files is easy, I just loop through line by line, but I need to be able to jump down to the 6th line, and I don't know how to do that without reading each line to that point"

May 17, 2012I was wondering if anyone knew of a good tutorial for parsing data from a text file and then populating the data into multiple text boxes. I have a text file with information pertaining to my form. The text file consists of key identifiers for each piece of information needed and I was wondering how to programmatically fill in my form by parsing that data.

View 5 RepliesParsing A Text File In Order To Extract Data For Subsequent Calculations?
Oct 21, 2010I am using Streamreader to read a text file containing data such as the following:
IN;SC;PU;PU;SP1;LT;VS10
IN;SC;PU;PU;SP1;LT;VS10
PW5;PU4179,27448;PD4179,29951;PD3244,29951;PD3244,30286;PD5494,30286;PD5494,29951;PD4555,29951;PD4555,27448;PD4179,27448;
The final goal is to use the numbers next to the PU and PD characters to perform specific calculations.
Essentially, I think the code needs to do the following:
1. Read each block of characters ending in a ";"
2. If the block commences with anything other than PU or PD, discard it
3. Extract the numbers in such a way that calculations can be performed. The following is an example:
x y
PU4179,27448;
PD4179,29951;
[Code]....
Essentially, there will be hundreds of these rows and I will need to sum up the deltas so that a specific formula can be applied.
I have tried doing this a number of ways but each seem very inefficient (using text boxes to store/swap data and creating additinal text files are 2 methods I have tried) and so I'm looking for some direction.

I've written the following code which does find the blocks, but when I try to parse its children to get its element fields (date opened, person requesting, history...) it instead pulls every element from the web page, not just the children.Is there a way to just parse the sub-fields under a particular DIV?

Reading Data From A CSV File?
Nov 24, 2009I am working in VB.NET 2003 and here is the issue of the day (for me):
I have an application which is supposed to read data from a CSV file one line at a time then pick out the 9th item ( a number) in the line and then add these numbers together for a total. The problem is the routine does not get beyond the first line. The code is as follows:
Dim total As Decimal = 0

How do I get this routine to advance to the next line of the CSV file and continue to do so until it has read the last line?

Reading In Data From A Text File?
Dec 4, 2009Ive made a program that reads in data from a txt file that has 4 columns, but it doesnt work if there are headings to the columns or any other kind of text at the top of the file. I basically just want to be able to skip any text at the top of the file, either by the user specifying how many lines to skip, or by code that can calculate how many lines to skip.
At the moment, the code opens the file, calculates how many lines there are in the file, redims an array to this size, closes the file and then reopens it so its ready to have the data read.
This is how the data is input into the array at the moment:
ReDim data(lines, 3)
i = 0
While Not (EOF(1))
[Code]....
I was thinking a possibility would be to use a try statement so that if the data is a string, then it skips over that line, but i couldnt figure out how to put it together.
Reading Only Certain Data In A Text File
Mar 31, 2008I am currently trying to write a program that will do the following. 1. The user will open a .txt file that needs to be converted into a CSV file. 2. The user will then click on a button to convert the file. 3. The program will parse the .txt file for the necessary data and will then write the data to a new CSV file. So far I am sure that I can write the code which will open the file and which will save the file to the new format. Where I am having problems is with the .txt file format that I have to work with. [Code]
Each field is fixed length with the empty space in front of the starting numbers being a field. I have been unable to find any code that would show me how to parse only certain data from this .txt file. What I need it to end up looking like is this: [Code] The program itself needs to be pretty simple as the .txt file will only have at most 25 to 30 records. I was thinking of using a StreamReader to read the data into an array, but I can't figure out how to get just the data I need out of each record.

Reading And Writing Data To A Text File?
Sep 28, 2009The program that I am writing has three default variables that I would like it to store and also be able to change. I have them in a text file called "settings.txt" The format of the text file is as follows:
Default Source "I:DCIM101MSDCF"
Default Destination "C:Documents and SettingsChristyMy DocumentsMy Pictures"
Default Backup Destination "D:My DocumentsBackupMy Pictures"
The field descriptions eg "Default Source" take up 30 characters, so the variable data starts with character 30. I know their has to be an easy way just to pull out the data from a particular line starting with character 30 but I can't find it.

Reading Name And Numeric Data From Text File
Apr 27, 2012I'm working on a program for a side business I run with a friend, who is a non-programmer.I've done a program before, using IO.StreamReader and IO.StreamWriter to read and write lines to a text file.
But now, I'm working on reading text data (it's output from an old legacy program) that reads a first and last name, and the customer number (6 digits) from one file.
Then, it uses the data (customer number) read the first time to cross reference the zip code and status from a second file, and display it.
The Data in the Text Files are as follows:[code...]
How would I begin parsing for the first and last name, and the customer number to assign to different variables?In the line that references names.txt I meant to put customers.txt.
That's a snippet of code I took from a previous program, so I know how to read the data, just don't know how to extract it.
VS 2008 Reading BigEndian Data From A File?
Jul 28, 2009Is there a way to set BitConverter to produce Int32 values from BigEndian-encoded bytes?I feel like there might be a way to temporarily "set" the encoding to BigEndian before calling BitConverter, but I haven't figured it out.Right now I'm just reversing the 4 bytes before calling BitConverter, I guess I could create my own function that adds the bytes with the appropriate multiplier, but it seems a little inelegant if it can be done simply with BitConverter.

May 23, 2011Here's what i've got so far, i've written all of the data that i'm going to put into my config file, however i'm having trouble reading the specific string values that I need from that ini file. The parts of the ini lines I want to get are the values in between the I've tried using streamreader a couple things but i'm having trouble figuring that out. I need to parse each line of the ini file to get that value in between the single quotations, so that I can set the value for my richtextbox background and text color as well as a few other things that i've set up in my notepad including tab spacing and so on. lots of these different values need to be converted from a string value to integers, and boolean values as well. (4 of them, the rest of them don't have to be changed because they are already string values when my application reads them to determine it's application load settings.
EDIT: I just noticed in the preview that this is from the version of the app where I had streamwriter write "______ value=" & Something to a file. lol some of the (')s are still in this version, so please excuse that little part. I had them in, but took them out so that I could trim data to get a value easier, but I want to use (')s hopefully when all is said and done.For example, just to restate what I want - in the ini file it will read [setting name] value='VALUE'I want to be able to "get" the string value of "VALUE" within the ini file between the 2 single quotations '
Reading And Writing Text File Data With Arrays?

So... How do we read the data into the arrays? NAME would be strName(), etc for all of them.

VB Express 2008 - Reading File And Use Data And Average Them Out
Nov 29, 2009I have a text file that the first part of my program writes data to, but for this second section, I need to read that file and use pieces of that data and average them out. The text file is setup up with 90 lines of data starting with the first 9 lines containing data and the 10th is a blank space. I need to read line 6, 8, and 9. I need to Loop through the file so I am using the Do While Loop. Where I am confused is when using the For...Next Loop to tell the program to read a specific line. If you have any info that can lead me to the answer that would be great. I would prefer you just point me in the right direction because I would very much like to somewhat figure it out in the process.
