I have some large csv files (1.5gb each) where I need to replace specific values. The method I'm currently using is terribly slow and I'm fairly certain that there should be a way to speed this up but I'm just not experienced enough to know what I should be doing. This is my first post and I tried searching through to find something relevant but didn't come across anything.
My other thought would be to break the file into chunks so that I can read the entire thing into memory, do all of the replacements there and then output to a consolidated file. I tried this but the way I did it actually ended up seeming slower than my current method.
Sub Main()
Dim fName As String = "2009.csv"
Dim wrtFile As String = "2009.1.csv"

Basically this is my problem, showing the results of a string. I am making a program for a customer and he wants to be able to extract a string or set of emails from a large group of text. In this case he wants to be able to copy a webpage and extract all the emails out of the webpage. The problem i am having is showing the results of the List(of string) Function. So far, I can copy the page, paste the content to a textbox and then i have a function that is supposed to filter out the emails and paste or Show them in a list box.
I dont know why but no matter what I do I always get this error:
Error1Value of type 'System.Collections.Generic.List(Of String)' cannot be converted to 'String'.
This happens when I try to output the return results to a textbox or list box.
Here is the code for the whole program:
Entire Program Code:
Imports System.Text.RegularExpressions
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code] .....
I have tried almost everything I could do, I am relatively new to string functions so that is my main problem.
I would like to step through each *.txt file in a given directory, open it, find and replace all, perhaps a thousand, occurances of a given string (e.g. "00/00/00"), then close and save file, and step to next one in the directory to do the same find and replace. I've been looking at filestream classes and regular expressions but don't see a clear way to do this.

I have a project im working on and im trying to change the font color of a specific string basically how vb does while your coding. (eg if i type dim it turns blue).I want to do this with a textbox in a vb application to show a topic of interest. It needs to be dynamic so when a user types it only changes the color of the specified string. I have tried
If TextBox2.Text.Contains("dim") Then
TextBox2.ForeColor = Color.Red
End If
but this changes all the text in the textbox to the color.
Assuming I have a Form, a Textbox and a Button like this : And a short text like this :
1
...<br\/> Baths: -\-<br\/> Sqft: 1,692<br\/> Lot: 7,013...
What I want to be helped is when I copy and paste the text into the Textbox, then I press the Button, it only display the numbers after the "Sqft :"It should be like this :
The texts and numbers are variable, it could be 2,203 or 8,232 or etc..., the "Sqft :" is fixed. Now what code should I use to make the Textbox display only the 4 numbers after the "Sqft :" ?
I have the first part done, ... I can delete all the text before spacific text, ... now I need to delete all text after a spacific point in a string of text.
I'm making a better, and more simpler BandWidth Monitor, and I'm extracting the Bytes Recieved, ... but just the value, and leaving out all the rest of the text.
here ya go, check it out.

View 8 RepliesThere's an INI file that I want to access and read information from. This is the complete content of the INI file in question: http:[url]....I believe it is because of the [ ] tags in that INI file. Because they work if I remove the tags.My program has a bunch of comboboxes, trackbars and checkboxes. These items will be filled by the information taken from the INI file.For instance, ini file has these lines;
bCrosshairEnabled=1
bDoDepthOfField=0
bFXAAEnabled=1[code]...
Example: I want the checkbox8 in my form to get checked if bFXAAEnabled has a value of 1 or unchecked if it is 0.
In Example : There's a text : You last visited: Jun 29th, 2011 at 10:27 AM And i need to get text
at 10:27 AM The code will be something like this :
