VS 2010 A Custom "split" Function That Parses Out String Delimiters?
Apr 21, 2010
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
My program uses parameters from the calling program in this format parameter1/parameter2/parameter3 parameter2 is a datafile path which may sometimes have a space like : C:Program Files est company
I did this as a work around Sub Main(ByVal Args() As String) dim cArgs as string="" Dim J As Integer For J = 0 To Args.Length - 1 cArgs = cArgs & " " & Args(J) Next And then used the string split function. Is there a proper way to work with spaces?
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 :

how to create a function that parses the input from a textinput.Text into an array of named reading, as string, and returns the number of arrays, or perhaps a negative number if there is an error in the input.

I have something like this below. The String coming in is "Hello My Name is John || John Smith"When i split, i see the full string coming in fine, i see My_Split(0) is set correctly, but i cant seem to get anything after the ||
How do I split a sting and add each to a separate textbox? e.g:
Dim strLL As String = "123.123, 456.456" Dim strL0 As String() = strLL.Split(CChar(", ")) For j As Integer = 0 To strL0.Length - 1 Debug.Print(j.ToString) Next This returns: 123.123 456.456
How do I add the 1st and 2nd values to separate textboxes?
I'm trying to split a string at a period character and save the two halves. I want to later evaluate the length of these, but I can't get the Split function to work at all.
Dim myArray() As String = Split(myString, ".", , CompareMethod.Text)I thought that this would split the two halves into an array as the help documentation said it would, but I just get the "A first chance exception of type 'System.IndexOutOfRangeException' occurred" error. This is really bugging me, as I can't even do this as the documentation tells me to do it. I try to run their example and the same thing happens.
I am trying to split a long string based on an array of words. For Example:Words: trying, long, array Sentence: "I am trying to split a long string based on an array of words."Resulting string array:Multiple instances of the same word is likely, so having two instances of trying cause a split, or of array, will probably happen.
The MessageText property is a multiline text, and the user must be able to set the text using the designer. The problem is that the designer doesn't allow to enter a newline directly for a string property.I want the same behaviour as the system TextBox's Text property, where you can click on the down arrow and write lines in the small text-editor that appears:How do I do that?

I'm trying to split a Yahoo historical stock price csv file, downloaded into a string, by what looks like a space character. I want a new row for each split. The split function works for other characters I see in the string. I suspect the characters may be a non breaking space character but I've been unable to split on them. This is the test csv file that is downloaded into the string: [URL] I'm trying to split the string like this:
Public Sub CheckUpdate(ByVal FileURL As String) Dim instance As WebClient = New WebClient Dim ApplyTo As String = instance.DownloadString(FileURL) asd = ApplyTo.Split(",") End Sub
I use it like this
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click NewUpdate.CheckUpdate("version.txt") Label1.Text = NewUpdate.asd(0) End Sub
(yeah I know i use it on local txt for now!)So with asd(0) it reads the whole file. If i check asd(1) I get IndexOutOfRange . So how does Split() work?

Is there a way to use the string.split command to get a section of a string without using an intermediary array?for example, if my string is "1 2" and I want to get the "2" part using string.split(" "), is there a way to avoid creating a new array, and just get the bit of the string I want in a single line?
After having some trouble in my own code using String.Split and the Split(String(), Int32, StringSplitOptions) overload, I decided to look to the MSDN.I copied the entire VB.NET code example from this link: url...I placed it in a new class, and received the following errors (same errors as my own code example):[code]Why can my code not recogognize the string() parameter overloads to String.Split? Remember, i took the code from the MSDN link above, copied and pasted and it still did not work.I am counting on using the string() instead of char() overloads shown here: url...

I created a STRING SEARCH function in C/C++ - and I'm trying to use it in a multi-threaded situation in VB. I started this problem in a thread in the C/C++ section of the forum - here [URL] my last post shows me getting this error trying to call the function. Ran the code - got to that point - and in the immediate window I did
I had a question regarding the split function used in Visual Basic. As of now I have written a function that brings in a string value. The string value returned will probably look like this "List1;List2; Field1,Field2". My goal is to use the split function for this string to put all the lists in one array and to put the fields in another array.
The problem is between where List2 and Field1 are. I don't want Field1 to be placed in the list array. I'm thinking there might be a way to do this by parsing but I'm not sure. Here is my current code below.
Dim s As String = GetSetting("ReOrderList", properties.SiteId) Dim affectedLists() As String = s.Split(";") Dim affectedFields() As String = s.Split(",")
