Retrieve A Specific Value In Text File?
Feb 18, 2009
I have an Intel Hex file with multi-line hex values -
100000010203320AE1100580099A23F0E26007E3
1001000E0223625AF16004800A9F24F0B2701742
I need to retrieve specific values in some addresses. E.g. If I want to read the 8th byte of the first line, 0x0A and the 9th byte of the second line, 0xF1, how to read them by opening this file?

Hi, i'm trying to use the treeview to display the text of a rtf (rich text file) file when an specific node if clicked.HomeOMGWOOTFor example, if i pick OMG, i want the text of lol.rtf to be displayed on a richtextbox. But somehow i just can't manage to get it... I know to import the text of a .txt file to a textbox, but using the treeview makes it more complicated.This is the code im using right now:
Private Sub TreeView1_NodeMouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.TreeNodeMouseClickEventArgs) Handles TreeView1.NodeMouseClick
Select Case e.Node.Index
Case 0
[code]....
Another thing is, that i can't import the *.rtf text into a richtextbox and i don't know why.

I'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.

I have a little question about txt-files...This is the case: I am going to make a small software for editing particular parts in text files, so you don't have to do it by hand. In this program, i need to find several words in a text file and retrieve the text or number that is after the the "="-sign, and then replace that info. Then, I want to use the information it retrieves to add some text in the end of the file.
P.S. There are 36 differet words to search for, and some of them will occur in several places, so i want the data from those words that occur several times in an array. And the data i want to retrieve is AFTER the searchword and a "=", so i dont want the searchword or the equals-sign included. Can someone explain to me how to do this?

I am reading a text file line by line using StreamReader.Readline(). After reading a line i have to check whether some fields of the line which is read are present in the rest of the file or not. What i am doing is that after reading a line from the file i am passing the streamreader to check whether there are multiple entries. i am trying to use line.Length() to get the length of line, so using this length i can go back to the line
my code:
Dim pos as Long
sr = File.OpenText(filepath)
While sr.Peek() <> -1
[code]....
my problem is that it is not giving me the expected line or it is skipping some part of the line.how can i return back to my line?

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 was wondering how I would go about replacing a specific line of text with different text, and then later reading a specific line of text (from the same file). The text file has a lot of lines, and basically the layout is like this:
Something1 Data I want to read
Something2 Data I want to read
Something3 Data I want to read
Each line has a specific word, and then after that word is the data I want to use for the form.

There's an INI file that I want to access and read information from. This is the complete content of the INI file in question: http:[url]....I believe it is because of the [ ] tags in that INI file. Because they work if I remove the tags.My program has a bunch of comboboxes, trackbars and checkboxes. These items will be filled by the information taken from the INI file.For instance, ini file has these lines;
bCrosshairEnabled=1
bDoDepthOfField=0
bFXAAEnabled=1[code]...
Example: I want the checkbox8 in my form to get checked if bFXAAEnabled has a value of 1 or unchecked if it is 0.

How to read from a line in vb .net, I need to do the following:
change the line in a text file
[Path] = "c: hiscertainpath"
With this line
[Path] = "c: hatother
ewerpath"
These paths will most certainly be different lengths, so I need to either replace what's in the quotes or erase the line completely and enter a new one, but in the same spot, not appended to the end of the document.
