.net - Why Does TextFieldParser.ReadField Remove Consecutive Newlines From Middle Of A Field
Nov 16, 2010
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(",")

I use a textfieldparser to read a csv file in my app. I set the delimiter to a, Problem is, if there is a field that contains double quotes, the textfieldparser fails. So if I have Example",test. it fails. If i remove the " it works. That's quite odd. How can I fix this.

I've managed to get my CSV file opened and the individual elements of each line read into an array. I've also managed to count and list the number of elements in the first row (i.e. the column headers).
[code]...
listOfNewFileRecords.Add(currentRow)' ADD EACH RECORD TO THE LIST AS THE FILE IS BEING READ Now the next stage is to access various cells within the whole opened file, so that I can condition/modify the text.So does 'ListOfNewFileRecords' have a way/method of accessing a particular element, in each record of the 'List'? I've tried using the intellisense, but can't make enough sense out of it to get anything to work.

I am trying to remove all spaces from a text field when a form is submitted so that the contents of the post code field match those in a database...
If drSet5c.Tables(0).Rows(0).Item("post_code") = UCase(Replace(tbPostcode.Text, " ","")) Then
response.write("Postcodes match")
[Code]....
So if the postcode in the database is AB12CD and the user types AB1 2CD the space is removed on submitting the form and the match statement shows. This is not working though.

I have a VB method
Public Sub append_text(ByVal s As String)
f1.TextBox1.AppendText(s)
End Sub
which is called over COM from C++
_bstr_t b(L"test
new
lines
");
ATLENSURE_SUCCEEDED(t->append_text(b));
But the text box ends up saying
testnewlines
Without the aforementioned new lines.Why is that then?

I'm writing a web crawler for a specific site. The application is a VB.Net Windows Forms application that is not using multiple threads - each web request is consecutive. However, after ten successful page retrievals every successive request times out. I have reviewed the similar questions already posted here on SO, and have implemented the recommended techniques into my GetPage routine, shown below:

This is my first post on here--I've been teaching myself VB via forums like this and MSDN for about 2 years now. I'm programming a computerized economics experiment, and I'm using a communications package that a guy I worked with developed. He and I have been going back and forth trying to figure out what the heck is going on.
The upshot of the communications package is that there's a serializeable MQMessage class that we send back and forth, essentially just a package of an integer (Type), string (Text), and Object (Data). Most of the time, this goes according to plan.
The problem is this: If the client receives two or more messages back-to-back, the client stops raising the MessageArrived event. (and presumably, the same would hold true for the server--I should test this, but jeez-oh-man, I've been running test after test for the last week).It's still connected, as on disconnect it throws the "Socket forcibly closed" exception. When it receives multiple messages sequentially, it's still receiving the data, it just never knows when the first message ends, and the buffer just keeps filling and filling. The problem seems to be that it can never successfully Deserialize the MQMessage object, and so it returns Nothing on the getCompletedMessage function and just keeps adding to the buffer (ABuffer.Length goes 1024, 2048, etc.).

I'm trying to load some data from a MySQL table and sort it so two equal rows doesn't come consecutive. I've been trying to do this on the server-side, but it looks like it's impossible. So I'm wondering if it's possible to load the data into a dataset and sort it there or something like that? I'm open for all solutions, both on the server-side and client-side.

This was a difficult question to google. I have an Order class with a couple of dozen properties such as ClientReference, ShipMethod, etc. I use databinding to bind this class to an Order form. If a user enters an invalid shipping method, an exception is raised in the ShipMethod property and a validation error is displayed to the user. But I'm trying to use the same Order class within an OrderImport class whose job it is to take a flat file and create multiple orders. The problem occurs if I'm assigning to a dozen of the order fields consecutively, and say the first one causes a validation exception. If I have all dozen assignments occuring within a single try-catch block, the next 11 assignments will be skipped and I'll only be able to record one validation error. I could solve the problem by doing a dozen separate try-catch statements, but that doesn't seem very elegant.

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.

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 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
Dim safeFileName As String = IO.Path.GetFileName(Me.OpenFileDialog1.FileName)
Using myReader As New Microsoft.VisualBasic.FileIO.TextFieldParser(safeFileName)
