I am trying to read in demographics from a text file. What I am trying to do is use the commas in the text file as a stop and starting point for each field. Instead of explaining all will be clear once you look at the code.
Dim filecontents As String
Dim newlineindex As Integer
Dim numindex As Integer

I have several files that I am reading in and 'scrubbing'. The scrubbing is simply taking certain HTML tags and changing them - no big deal.When I read in the files (one at a time), they read and then I scrub them.The files stop reading mid-way *no matter what* the encoding type There is no stop character or anything, it is simple HTML and I do not see any reason why the file isn't being read I have attached one of files that is having a problem and the code is quite simple:
Dim oRead As New System.IO.StreamReader(Dir & "" & FN, Encoding.ASCII)
EntireFile = oRead.ReadToEnd()

Ive 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))

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.
I 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.
The 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.
I have a text file which has the format
A;UK;WN0XKKF;XX377SL;POSS TRADE MONITOR
A;UK;N6HXS;XX361NG;POSS TRADE MONITOR
A;UK;DU58XPK;XX37 6UR;EXCESSIVE WASTE MONITOR

I am trying to read the code, and pull out the 3rd, 4th and 5th set of each line in to a datagrid.

I'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.
Even a primer on just reading/writing to a text file would be golden. The array confuses me further, but understanding the data is primary.
Basically, we're writing a program to manage inventory for a bar. Fields and a few lines are below. The delimiter is "||"
So... How do we read the data into the arrays? NAME would be strName(), etc for all of them.
how to write and update existing data.
UID||BREWERY||NAME||SIZE||FORMAT||SEASONAL||PRICE||CASECOST||CASEQTY||BREWERYLOCATION||BREWSTYLE||ST YLE||ABV||CLASS
A0101.12B||Abita Brewing Company||Abita Amber||12

I have a text file called: list.txt This is a list with all kind of lines like this:
14II_ARM_S_CLO_CLO_CLOVERIDS_PROPITEM_TXT_01194611IK1_ARMORIK2_CLOTHIK3_CLOAK=TRUE==200050000====PARTS_CLOAK=1==11=1===11_NONE Ofcourse every line has different numbers and letters.
The complicated bit is this:
I want to let Button1 check whats in TextBox1.Text and search "list.txt" for it. When it has got a match (there is only ONE of these numbers in list.txt).For example TextBox1.Text = "IDS_PROPITEM_TXT_011946". And I search for that so I find the line above. Now I want 3 other textboxes which show the 21st, 22nd, 23rd column/number after "IDS_PROPITEM_TXT_011946". And they should be editable by changing those 3 textboxes and clicking the apply button.How can I best do this, and please give a little example.
This is what i wanna do and dont really know how:
When i click button "StoreX":
if X.ini does not exist it will be created at the same folder as application
NumericUpDown1 value stored at X.ini line 1

The following code suppose to:
1. Read line-by-line a txt file with more than 500,000 lines, (each line 521 characters long)
2. extract an ID No from the line
3. query from a database for LCCIStatus
4. concatenate the value of LCCIStatus to the line
5. write the line to sample.txt
My problem is, this code works perfectly with the test file of 8000 lines but fail with the actual files which have over 500,000 lines. FYI, the test file contains data which I cut and paste from the actual file.

Is 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.

I am in the process (slow process) if learning vb.net by trying to create a simple application that will read and write (save) chosen information to a text file. The application has text boxes (name, email address, etc) and I want to read information from certain lines in the text and place in the given text box.[code]When I start debugging mode it does not display the text until I click onto the text box and it's displaying the first line of text in the file.

View 6 RepliesI 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.

here is some code i have so far
