VS 2010 RegEx - Split On Comma Character, Excluding Those In Quotationmarks?

Aug 9, 2011

Given an input string like the following:I, Need, Some, Coffee, Before, I, "Fall, Asleep" I need to split this into parts like so:

I
Need
Some

[code]...

Splitting on the comma character alone is easy enough, but how can I handle the quotationmarks? Regular expressions is not on my strong side, and I have been googling for quite a bit without any good results.

Comma Delimited Line Split?

Jan 9, 2011

I have spent a long time debugging an application that occasionally goes awry, it ends up that the problem is that the comma delimited text files that I am looping through occasionally inserts a comma within one of the fields.

At any rate, I was loading the text file into Excel to try and spot the error which was of no help, somehow Excel parsed out the field correctly and didn't use that extra comma as a delimiter. Is there any way I can get my application to do the same?

And example field value is: "7-8-ALL (1,2&3)", but of course my split code turns this into two separate array values.

Split An Array Of Text Into 3 Textboxes Using VB 2010?

Apr 23, 2012

I so far have created a randomizer in Virtual Basic 2010 that:Takes people's names that the user imputed in form2 into an array (split by spaces).Randomizes the array Displays the array with a consecutive number and period behind it for each name that was imputed.

Here is the source code:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim names() As String
Dim i As Integer

[code]....

Pay attention to the last bit. I want to take the variable txt and split it. Then I want to take the first 10 names and display them in RichTextBox1, take the next 10 names and display them in RichTextBox2, and display the last 10 names in RichTextBox3.

VS 2010 : Split Acting Different With Word Document Text?

Oct 12, 2010

I'm having some difficulties chopping up a word document. I think the problem may be that it's 900+ pages, but I'm not completely sure.The separate documents within the document file are separated by x of 100 documents. I'm trying to split at the "of 100 documents", however when I try to split the string that I put this word document's contents into, it will only split with the first letter I give. So, when I try to split it by "of 100 documents", it will only split by "o".

Dim sr As New StreamReader("C:Programming filesPracInfo.txt")
Dim openWith As New Dictionary(Of String, String)
Do While sr.Peek <> -1
strHold = sr.ReadLine()
' here I would like to use the String.Split method on strHold and then put that into the Dictionary using Dictionary.Add(Key,Value) but not sure how to do this????
Loop
End Sub
