Parsing A Line Of Text

Jun 22, 2010

I am attempting to parse multiple lines of text from a text file using regexpressions. I am using vb.net with visual studio 2008. At the moment I am filling my datatable with the text file information and am able to return each line of text and parse the first set of numbers that I am attempting to break up. I have multiple string with varying lengths of character lengths and numeric lengths however the delimiters are sometimes different. Sometimes will be whitespace and sometimes will be whitespace and chars. But is always 2 spaces. Here is my code:

Parsing Multi-line Clipboard Text Into A Single Line And Pasting Into A Textbox?

Feb 7, 2011

a user copies multiple lines of text (say, from an email) into the clipboard. Based on my observations, when one tries to paste the text into a single-line textbox, only the first line is actually pasted in. (I am aware that the "obvious" solution would be to set the Multiline property to True, but there are reasons I am looking to avoid this and to put multi-line data into a single line.)

In the TextChanged event handler, I wrote code that parses the clipboard data to successfully convert it to a single-line, comma-delimited format.

Private Sub txtMassTrackingNo_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) _
Handles txtMassTrackingNo.TextChanged

Parsing Richtextbox Line Color Text?

Aug 17, 2011

Going in more depth currently over on MSDN on how to parse a color line to the richtextbox.

To explain more imagine you have various types of information. For example sake say a....

PRIVMSG
NOTICE
MODE

being parsed to the richtextbox. Now we have one sub to deal with all these three messages from the server but each needs it's own color.

Now currently i can only think about on each arrival of a new message loop the RTB length and match a a string.

Is there any way when we append to the RTB with the new string we can parse that new strings color also?

VS 2010 Parsing A Line Read In From A File?

Apr 20, 2012

I am reading in a line in this format: AL93895200 How do I get each of the items in the line that are separated by a space. I think it should go something like this:

Dim line As String = fileReader.ReadLine() Dim fields() As String = line.Split(How do I get it to split at the spaces?)

But as you can see, I don't know how to actually get that to work.

FCL For A Method That Will Allow To Erase A Line Of Text From A Text File And Replace It With Another Line Of Text

Dec 19, 2008

I've been looking through the FCL for a method that will allow me to erase a line of text from a text file and replace it with another line of text. Neither the StreamReader nor StreamWriter have a method for replacing or removing Text from a text file, as does the string object. Are there any available methods for erasing just certain lines of text from a file, and then replacing them with others?

In my code, I'd like to locate a certain line in the text file, and then at that point in the text file, use a For...Next Loop to replace each successive line of the text file with new text:

Dim user_data_file As String = "user_data.txt"
edit_input = New StreamReader(user_data_file)
Dim edit_line As String = edit_input.ReadLine

[CODE]...

However, I can't find any methods that will allow me to do this.

VS 2008 Reading Text File Line By Line - Put Into Text Boxes

Basically what I'm trying to do is read a text file line by line. After each line is read, it will put each line into a separate text box. I've been trying to do this for a while and so far I haven't been able to. I tried using a for loop, but that just put all my lines in to one textbox.

IDE :: VB2008 Express Form Designer Error : An Error Occurred While Parsing EntityName.Line 2, Position 62

Nov 24, 2010

The Form Designer in the IDE is no longer working properly. When I create a new project, the Form Designer will work, but after I save it and close the IDE and reopen the next day the Form Designer no longer shows the form and instead says "To prevent possible data loss before loading the designer, the following errors must be resolved: An Error occurred while parsing EntityName.Line 2, position 62" If I click ignore and continue, then it just displays a blank form with no controls. The problem appears to have started after I unistalled and reinstalled VB2008 Express.

Casting Or Parsing Of Text?

Apr 20, 2012

in vb, you can use text which is in textbox instead of numerical expressions. I mean, if I write 50 in textbox1 and also I can write like that code:

Dim result As Double = TextBox1.Text + 0.4

as you see, I didnt convert any type but it works in vb.net

But I want to learn what are disadvantages of this using?

(I am just talking about arithmetic operations)

Parsing A Rich Text Box?

Apr 24, 2009

I have a rich text box full of encrypted data split by ";" and I have

Dim Pass, Data, Game1, Game2, Key1, Key2 As String
Dim PassEnd, Game1End, Game2End, Key1End, Key2End As Integer
Data = showencrypt.Text
PassEnd = InStr(showencrypt.Text, ";")

[code]....

Pass gets decrypted ok, and Game1 gets decrypted ok. Key1,Game2,Key2 are all the same as Game1 though. Is there something I am missing? Why is it setting all of them the same? I've tried settings the Start of the InStr's at the previous End but it doesn't work.

Parsing A Text File

May 1, 2009

I'm toying with an idea that would require me to parse a text file that contains a SQL statement. (i.e. Select * From Customers) I would like to be able to programmatically via Visual Basic identify key words, table names, comment lines, etc.So, how do compilers handle such a task? How does a SQL database handle such a task? All of the parsing tools are for CSV files with some sort of consistent delimiter. I'm wondering if I need to read the file one character at a time and then do some sort of comparison.

Parsing / Reformatting HTML To Text

Nov 9, 2011

I'm a PHP/MySQL/HTML guy, but in the course of my work, I sometimes have to delve into Gatesland.I am working in VS2005 developing reports, and occasionally I have to write some custom code. This code is in (I believe) VB.NET. I avoid this as much as possible. It is my belief that if you have to use custom code in a report, you're doing something wrong with the DB, or with your query.Now, my boss (for reasons unknown) is storing data in the database as HTML. This data is historical, having a month and a dollar amount, and comes in a form like this:[code]I know this breaks even 1NF. I did not design the database. I simply must suffer under it's schema. See, the developer did this so that he could just read in a field, and dump it straight out to an echo/print statement when forming up the HTML. Unfortunately for me (the report developer), HTML shows up as verbose text if I dump it out as a field in a text field in a VS2005. So, I need to strip out he HTML tags, and replace them with appropriate values.

I am first trying to strip out the <th> data, and print it out with appropriate line feeds and carriage returns. This is the code I am trying to use:[code]Now, far from doing what I intend it to do, it simply returns the jubilent result "#Error". Wonderful. I'm sure the client will be happy.There must be some simple syntax errors or something going on there, but I am nowhere near an expert with VB.NET. I've used VBA extensively, but last time I used it was about 3 years ago. I'm hoping I can cash in some of that positive rep I've got, and get some much needed help in the dark wilderness of Microsoftia

I'm trying to parse a text file. First I plan on extrcating each line, then extracting each field by searching for a tasb.When I use InStr to search for a (return for end of line) or (for tab) I always get a zero. But if I put in a visable letter such as a I got a 5.also I tried /r, /n and all return a zero.The file looks as follows:

Save And Text Parsing In Program?

Feb 9, 2011

Im new to VB and am working on a program for work using functionality to replace the use of hyperterminal and excel macros to dump data from a plc to a spreadsheet. I have the program setup and dumping the data to a rich text field, but this is about as far as my experience will let me go. So here are my questions:

1. Im wondering if it would be possible to use the text parsing method to sort the data into fields by first using a comma to delimit the fields and then tab (not sure how to put it as a character) to start a new line. this will then be displayed in a data grid view and later form there dumped to an excel file. i was also looking at the serial port functionality to see if it could parse too, what would be the best way to go about this?

2. I also need to be able to open more than one instance of my program and load connection settings into it (like what can be done with hyperterminal). Im wondering if it would be possible to use the save dialog to allow the user to save the settings to a file and open the settings file when launching any given instance?
