I need to load and parse a text file and extract data between points on any given line. I can load the file, but it's the parsing that's giving me headaches. e.g. "Phoned Jim and arranged for John to attend site" First I need to search for "Phoned" because the line always starts with that, and then I need to extract "Jim and arranged for John"

How can I parse a text file and extract the data to excel file. The text file is in the following format
CustomerInformation

I need to parse some text to extract the name/path of an image file inside an X file. The part of the file looks something like this:
TextureFilename {
"C:\\Users\\USER\\Documents\\Map\\Textures\\Grass01.dds";
}
[code].....
I'm running into a problem whenever I try to parse a text file by each line. I know I could use stream reader to read line by line but it is a lot easier to simply use split() and I would also like to know the reason why split() doesn't work.
For example, I created a file "test.txt" and filled it with the following text.
text1
text2
text3
then put the following code in the load event of the form (a button click would work the same).
[Code]...
# TAG NAME = is saved to a file using the code below but when I load that same file back into a RichTextbox Control using additional code below, I get inconsistent results as I try to parse the text. Has anyone else had this problem?'Save the contents of the RichTextBox into the file.richTextBox.SaveFile(saveFile1.FileName, RichTextBoxStreamType.RichText);'Retrieve contents of File into RichTextBox control Dim logData As String
logData = System.IO.File.ReadAllText(path + "\" + filenname);
Suppose I already know the line number such as row 100 in a text file. How can I directly get it without many codes?
Code:
.....
99 Dim s1 as String
100 s1 = "Test"
101 MsgBox("Test Ok")
[Code]....
My text file look like this[code]...
I want to extract those lines according to value in ( ).
I need to parse a text looking for the string - [[Extract|xxxxxxx]] and extract the xxxxxxx characters.How would I do this?
View 2 RepliesI have a text file data to insert into a database for report
ITEM01,Toy
ITEM02,Card
Let me briefly list down the steps i took to achieve my result.
1) Insert data into Database using text file
2) Display the records from the NEW Database(Item2) using DataGridView
3) Using datagridview, i use to checkboxes to determine the selectedRow
4) Once the selectedRow are selected. I press on Delete Button
Delete Button - Update the Item2 Table field 'Deleted' to 1 - Delete the ItemID by using datagridview selectedrow cell value Which means in 1 loop, i process two database transaction.. Is there something wrong? How do i shorten the process to just delete the item without querying two database.
To simplify what I am trying to do, let's say I have a text file with only one line of data.
The data in this case is color info for one pixel:
Color [A=255, R=255, G=200, B=128]
What I am trying to do is read the text file and extract the hex color info and save them to their own variable.
So once the code has run, these should be the contents of the three variables.
RedData = 255
GreenData = 200
BlueData = 128
I have managed to get something to work but I know the code is terrible and is incredibly slow when I try to run through hundreds of lines in a text file.
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
Dim PixelData As String

I have found the above code from the net and it works fine as I would expect. I know this because I have added a put the String StoreFile into a text box and it worked. From what I understand about the code above is that we are reading the file test.txt until we reach the end of the file and we are storing it into a string.
What I would like to do is either:
1. Search the String StoreFile until I find the text of my choice, and then extract the characters around it. See attached txt file.
For example, if I wanted to search for MNAUSD in the attached txt file, I want to grab the values on the line (highlighted in blue) and make them available to my program and ignore everything else.
"MNAUSD",UNITED STATES,US $,M,1.558850,1,1.369850,1.113500,L
I know these files are comma delimited, but I would rather use a regular expressions if possible as I have other files that are not comma delimited, so it would be ideal if I have a regular expressions to handle the search and extract
OR
2. Search the File test.txt LINE BY LINE, until I reach my search text MNAUSD and then extract the same values as above.
I 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.
is there a way to parse data from a command line tool such as netstat -b 2?
View 2 RepliesI am making a small program that will parse the end of a game log file to calculate DPS, hit %, exp .. but I am having trouble with stopping the code from continuing to read matches I find in the last line. Even if the last line has changed it will continue to find say "You hit" and parse the dmg done in the line.

Basically iv got a form, and the fields are
"Full Name":
"Amount Contributed in �":
below the form i have a button that saves the data to a text file called 'mailinglist.txt'
So i enter the data into the fields and click the button like as follows:
Full Name: John Smith
Amount Contribted in �: 40
However..... when i go view the text file it displays John smith40, which i want a space between the name and the numeral.
Also as i want a maximum of 5 people added to the mailing list, i would like a function that lets me somehow "adds" an extra 4 people to the text file without overwriting the 1st name, and uses the same "current" form displayed to the user.
Here is the code as follows:

View 14 RepliesBasically i have a 500 line javascript file i made that runs in grease monkey (a add on for firefox ) I'm using vb.net to "compile" this script depending on certain check boxes.
So for example. (this is part of my script)
#RegionCapsEnforcer
var array=document.evaluate("//*[contains(@class, 'postbody')]", document, null, 6, null);

and so on. So if chkCapsEnforcer was not checked it would skip that part and go to chkRevealUrl and if that was checked would get that bit. Then once it has gone through all the checkboxes it would write the enabled bits to a text file.
