String From Regex Split Contains Extra Blank Values?
Sep 5, 2010
i have a small program to run through a log file and extract data from it which works, but the array it puts out has a blank value before and after the actual data values, and it confuses me why that happens, i dont really understand why and was hoping someone here knew! the parts of the code related are below
Dim rgxSessionStart As New Regex("^Session Start: [A-Z][a-z][a-z] ([A-Z][a-z][a-z]) (dd) dd:dd:dd (dddd)")
Dim substrings() As String
substrings = rgxSessionStart.Split(LineIn)
a sample line that it would match is Session Start: Sun Aug 22 00:00:00 2010 which WORKS, but the values of the array are "","Aug","22","2010","". so its not a critical problem because i can still get the data from it, but those blank values are puzzling and i feel like maybe im doing something wrong with the syntax or method for them to be there.

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.

I have some code that splits a session into strings by a -
My session looks something like this 123-456-789- and I split it like this
Dim MyString As String() = Session("MySession").Split("-"C)
And i've got a some code like this
Dim x as Integer
For x = 0 to MyString - 1
Response.write("Ref: " & MyString(x) & "<br>")
Next
This writes the code like this
Ref: 123
Ref: 456
Ref: 789
Ref:
So it's adding an extra Ref where it shouldn't be because there is no data after the last -
Is there a way to stop this adding in the extra one?

i'm using Regex.Split to convert a text file's string to System.Array. The end result is System.Array of 211 strings.
Now what i need is to convert System.Array to a Byte of 211. How would I accomplish this?
System.Array to Dim x(211) as Byte?? Sample code would be great here. I've already visited many sites on this subject with no luck. code below.

I have an rdlc report that always produces the last page in blank. In this page, the header and the footer are printed but no data is shown (all data finishes in the previous page). I already checked and re-checked the horizontal and vertical printable areas and all the report definitions fit into these areas (if not, a blank page will be produced in between each page, I guess). If the report has one page, two pages are printed, if there are ten pages with data, eleven pages are printed

Just have a list of words, such as:
gram (g)
kilogram (kg)
pound (lb)
just wondering how I would get the words within the brackets for example get the "g" in "gram (g)" and dim it as a new string. Possibly using regex?

I've been asked to re-write an application that was written sometime ago by another programmer. This application reads data from a database table, massages it, and then writes out the results to a text file that is later shipped off to another company. When I run my new application, it generates a file that, according to the byte count, is twice the size of the file output from the old application. However, to look at the two files with note-pad they look identical. I found that by using 'Ultra-edit' that the new records have a low-value byte hex '00' between each real character.

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

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.

I'm trying to add some extra key/value pairs to a combo box using VB.NET. The initial item list is generated from a hashtable, which contains a collection of objects.I've managed to add the extra values to the box using the Add method, however I now run into problems when reading back the selected item from the combo box because some list items are objects, while others are strings.
My best option seems to be to load the initial data as key/value pairs by looping through the hashtable, however this doesn't seem to be working too well either because I'm still getting errors.I'm getting frustrated because it's taking me hours to do something that should take 5 minutes!

I've used VB to connect to Excel and get the titles of the different columns in a spreadsheet. These then display in a drop down combo box for the user to choose from. I'm getting lots of empty values in my combo box because not all the columns in Excel have titles. How would I go about telling it not to display them?
Excuse the easy question but I've only started learning to code a week ago.

I have a program that uses a richTextBox to append and save file locations. Each line in RichTextBox1.Lines is added to a listbox for the user to see the files. The format of the richtextbox output is shown below:
C:UsersJordanDownloadsfile.ext
C:UsersJordanDownloadsfile2.ext
C:UsersJordanDownloadsfile3.ext
I have a button on the form which can remove an individual file from the ListBox with the code shown below. The problem I am having though is that the RichTextBox text is ending up formating like shown below. If I remove the C:UsersJordanDownloadsfile.ext for example, the RichTextBox text will show as:
<vbCrlf>
C:UsersJordanDownloadsfile2.ext
C:UsersJordanDownloadsfile3.ext
