File Io - Textfieldparser Delimiters .net
May 14, 2012
I'm currently busy coding a hangman game in VB.NET.As a wordlist, I have a textfile containing 1520 words, each one seperated by a new line. The best I could think of to get a random word is with a Randomize() function. Then getting the word from the line # which was randomly generated.
[Code]...
Is there any better way for me to extract the word from that random line? If not, what would be the delimiter I should use for this and how do I quickly change the breaklines into that new delimiter without resorting to Office?
Also, how can I use the textfieldparser to get the file from resources? When I tried using my.resources.filename instead of "filepath", it gave me an ArgumentException due to "invalid characters in the path".

I've been using VisualBasic 2008 Express Edition for a little while now, and I've gotten the hang of a few things like nesting and basics like that. I love learning everything I can about it, and so I'm working on a program that's got some things I'm not so familiar with involved. I'm not sure exactly what it is I'm looking for help with; as I'm sure some of you may know, there are many different ways to accomplish the same task--it's just that we don't always know the simplest solution, unfortunately. So anyhow, I'd like this program to do a couple of things... Firstly, to read in data from a text source and display it accordingly, and also to use that data in a list box and compile a new list from the original one.I've got a rather vague idea on how to do the first objective to put it nicely.I've read a little about delimiters and such, but the problem is that everywhere I look for tutorials or examples, I'm not really seeing exactly what it is I'm trying to do.Here's an example of the text I'm trying to parse/read/whatever it is:|Name of thing|some data|blah|blah blah|
In this example, I use the vertical bar character (I don't know what it's called; it's Shift + for me) to separate data in a pre-defined order. Let's say I wanted to use this for car information, I guess.[code]Like that, only many more times. What I can't figure out though, is A.) how to make VB read every line within the text file and B.) how to differentiate each of those sets of data so that I can read them into labels on the form. At this point, all I do know is that that vertical bar (this thing) is what's called the delimiter. Other than that, I'm left to pulling my hair out.

I have a csv file which I am populating to a datagridview. I am delimiting it using "," and "space". My csv file has "," at first instance and "space" in next two instances. I want to delimit the first instance using "," and the second instance using "space" and the third instance though has "space" I wanna ignore that space.
My CSV file :

I am learning to use TextFieldParser to read a fixed width text data file. It works great. I copied code below. Question: How to stop at the end of each line because I need to add some code?
Using tf As New TextFieldParser(fileName)
tf.TextFieldType = FileIO.FieldType.FixedWidth
tf.SetFieldWidths(60, 30, 20) //three columns

I am trying to use Microsoft.VisualBasic.FileIO.TextFieldParser for parsing any format of tab delimited text file that user may have and show the data in web page in tabular fashion.I have sample tsv file with text qualifiers such as quotes saved in different encoding styles for different platforms such as pc, unix, mac saved using textpad. and I am trying to parse these using TextFieldParser. It works for all PC files but fails for mac.

I just can't think of an easy way to do this. It seems easy, but I'm not just sure how to do this. I want the software to grab a random word inside the bracket "{}". The "|" is the delimiter. Here are some examples...
Input #1: {Hey|Hay|Hello} How {are|r} {you|u} doing?
Output Example #1: Hey How r you doing?
If I execute the code again, this would output...

I am having trouble figuring out how to parse a string with delimiters. I have a text box which the user inputs data or what ever. I need to figure out how to parse the string and display it in a listbox, each word in a single line. Here is what I have so far, my book doesnt explain parsing very well and I'm stuck

I am having some trouble including tab and space delimiters in my multiple delimiter code (see code below). It seems I can not just add the <vbtab> and <vbCrLf> codes into my delimiters list so I tried to replace them beforehand with a Clean String Function (also see code below) but it didn't seem to work. Ultimately, I would like to add any delimited text file to my datagridview.
The code below is working fine except for tabs and spaces (including next-to-each-other separators) I am using Visual Basics Express 2008.[code...]

Just what the title says. I have a listbox with varied entries, all in one format:name, email, phone, age
When an entry is selected, and when a certain button is clicked, I require the entry to be removed from the listbox and the four categories from the entry must each go into their assigned textboxes.

It seems like in order to use "TextFieldParser " you need to include the path of the file to be parsed. Is it possible to use OpenFileDialog1 and then choose a file? I keep getting error messages.

Ok so I am taking jm advice and using TextField Parser instead of ADO.net to read my delimited files and then build my own datatablesFirst question is how would I query the data?I need to be able to have two tables, one with sold propertys and one with propertys still for sale.The table I created thus far has all the records, the problem and my second question is how do you allow for a null value ?If one of the records isnt Sold then it won't have a Selling Price therefore when I set my datacolumn to be of System.Integer type It is not accepted

I am using the TextFieldParser to read a 3rd party .txt Tab Delimited File Sometimes the file contains duplicate column names and subsequently I cant create my DataTable.
How can I check for duplicates first and change the name of the duplicate fields so I can populate my Table?
Example:
I have two columns called ST and would like to Change of of them to ST1 or something similiar to populate my table

I'm using the following code to read some values in from a tab delimited text file:

Parser.TextFieldType = FileIO.FieldType.Delimited
Dim comments(0) As String

As you can see I have set the HasFieldsEnclosedInQuotes property to true on the textfieldparser because I want to make sure I capture the data correctly if quotation marks are used. If I set the HasFieldsEnclosedInQuotes property to False then it all works (or at least it doesnt error anyway) but like I said, I need to have that set to true because otherwise if the line contained a tab character within the quote marks then my app would think this was two separate fields and process it incorrectly.

Is this class normally slow or maybe there is something in my process making it slow.I have to import 170,000 rows of data from a fixed length text file into a SQL table. It takes about 2 minutes in a DTS package on SQL server 2000. But we are migrating to a SQL 2008 server and since this code has several manual steps and does not manipulate the data I thought it would be easier to use the TextFieldParser object to handle reading in the data.
Here is the code:

I have a VB2010 project where I need to read a tab delimited 50MB file using Microsoft.VisualBasic.FileIO.TextFieldParser. This technique works fine until the reader encounters a Unicode character upon which it inserts the little square thingy. The obvious choice is to change the encoding of the reader to Unicode from the default. This would probably work fine but for most files but this one is fairly large and I get the error TextFieldParser is unable to complete the read operation because maximum buffer size has been exceeded. By the way this file can be read completely without the Unicode option. Making the file smaller or breaking it up really isn't an option. Is is possible to increase the buffer size or is there another way to read this data that places the data in fields like the textparser and allows unicode characters?

I am using VB.NET's TextFieldParser (Microsoft.VisualBasic.FileIO.TextFieldParser) to read a delimited file. However, when I try to read in a field with consecutive newlines within the field, the consecutive newlines are turned into a single new line. I would like the consecutive newlines to be preserved, but am unsure how.Here's an example file that I am reading in with exactly one field. The quotes are part of the file's content and there are three newlines (including the two consecutive newlines following line 2):
"This is line 1
This is line 2
This is line 4, which follows two consecutive newlines."Here is the code that I am using to parse and read in the file:
Dim reader as New Microsoft.VisualBasic.FileIO.TextFieldParser(myFile, System.Text.Encoding.Default)
reader.TextFieldType = FileIO.FieldType.Delimited
reader.SetDelimiters(",")

The end of the text document my application is reading is denoted by a character that I cant identify, copy or paste. I attached an image of it so you can see. I have no control over the formatting of the document so I can't change the character. During debugging it shows the same character as shown in the picture, but if I hit the little tack next to where the variable shows then it changes to "f". However, if I try to see if the variable equals "f" it returns false.

Is this function as efficient as I can make it or can it be done more efficiently? It takes a line of text and turns it into an array of values.If the value delimiter exists inside a string delimiter, that value delimiter is incorporatedinto that value. String delimiters are removed from the values, and so is any leading or trailing white space:
Public Function ParseStringDelimiters(ByVal Line As String,
ByVal ValDelimiter As Char, _
ByVal StrDelimiter As Char) As Array

I am using Microsoft.VisualBasic.Fileio.TextFieldParser to parse a CSV file that was created with Excel 2003. The parser is working great with the exception that it is converting extended ascii values to question marks! So if the file content was:

The TextFieldParser is returning

I have tried all of the encodings in the System.Text.Encoding package with no luck. I thought I had it with UTF7 but it was dropping other characters like replacing the + sign with a space.
