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.
My text file look like this[code]...
I want to extract those lines according to value in ( ).

I need to extract the whole string if the string has today's date on it. I have already coded a string that displays today's date in the following format - yyyy/MM/dd And I've coded the parsing links bit, now I need to simply search the Listbox and return the first string with the date. [Code]
View 11 Repliesi have a log file which contains hundreds/thousands of seperate XML messages and need to find a way to extract a complete xml message depending on the parameters given (values of nodes).My biggest problem is that even though i program a fair amount i have had very little contact with XML or the XML libraries of the languages i use and didnt think that a simple text parsing would be an elegant solution!I am going to attempt this in C# or VB.net

I've got an application that passes commands to a terminal window and saves all the output to a text file Here is one of the commands my application passes to the terminal
MyProcess.StandardInput.WriteLine("host " + device)
The output of which is
"HostA has address Y.Y.Y.Y"
this along with a whole bunch of other text is saved to a text file...my question is how do I find the sting "HostA has address Y.Y.Y.Y" in that text file and then extract the IP address and assign it as a string variable?

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.

Dim PixelData As String

is there a way to extract all the text from a Word Document in VB.NET without actually openning the file? I'm asking since it is a very time and memory consuming operation to open a word document, select all, assign it to a variable and the close the file.I have a routine the opens all emails in a mailbox and analyses the body and subject object for regular expressions. I would like to do the same for the attachment, if it's in Word. if it's not possible to extract without openning the file, can anyone give me the best way to do it so that the routine doesn't destroy my server memorywise?

View 2 RepliesI've been writing a weight program for flooded pressure vessels and I'm having trouble retrieving the data from the text files I've been saving. I know how to write the data to the text file, but retrieving it with OpenFileDialog is not so easy for me.The user has individual text boxes that they input strings or numbers into and when they save the file, each text box input is written to one line in the text file. For example, the first text box is for the username, therefore the first line of text that is saved is the person's name, the second text box is the customer, thus the second line in the text file is the customer name, and so on.
(Actually, the first line of text in the saved file designates whether English units were used or Metric units because when the user retrieves the saved file, English units will open one form and Metric units will open a separate form, so some If...Then statement will need to occur).I need to be able to read the first line, have either my "EnglishForm"form open or my "MetricForm" form open, and then have each subsequent line of text be displayed in their corresponding text boxes. I know I need to use ReadLine or LineInput, but I don't have a clue what to do.Assuming the syntax I've displayed below would just magically work (if only life were that easy), it would look something like this
If FirstLineOfTextInFile = "English" Then
EnglishForm.Show()
ElseIf FirstLineOfTextInFile = "Metric" Then[code]....
And so on...I read a lot of articles from the MSDN library and exhausted each link that I've looked through from Google and Bing, but most only retrieve data from the file to a single text box through some loop or streamreader and don't take into account multiple forms.
Is it Possible for me to read text from textbox control and write it to .txt file at specific location.
for an instance.... say below with quote is my Text in .txt file:
"THE QUICK BROWN FOX JUMP OVER THE LAZY DOG"

"THE QUICK GREY FOX JUMP OVER THE LAZY CAT"
so you can see the word BROWN change to GREY and word DOG change to CAT
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;

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 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"
