I have a stream reader going into an array with a .split on it:
strNstring = sr.ReadToEnd.Split(New [Char]() {" "c}, StringSplitOptions.RemoveEmptyEntries)
If the file is set up like:
the

Is there any way to set the split to fix this and just have them come in correctly?

I've set up a stream reader to get data from a serial file, functionality for that is already set up.
My problem is that the program seems to be missing out every other line of code in the file, which kinda defeats the point of a serial file. [code]...

From few days I am doing efforts to read web pages using webbrowser control in my desktop application. But it is very slower than my expectations(because I want to read lots of pages in minutes and browser control reads almost one page in 5 to 10 seconds), what I need is to read two or three tags written in web page.
So finally I decided to use something, which can give me only source code of page. I think StreamReader will help me to read it. I am not sure if it is flaxible with my purpose, or something else is there which can give me only html source code of web page.
I have written this code to read html code, but it gives error.

I have been using the following Stream Reader code for over a year now to pull information from 3 websites w/ no issues. Recently my users are getting massive amounts of "Timeout" errors. I have opened a ticket w/ the IT department but they have not found any issues (we are experiencing off/on issues w/ our web traffic speeds in our department). Per the code I have the timeout set to 20 seconds but the Timeout error occurs in only a few seconds from the System.Net.WebException.

I am downloading page data using the stream reader using readline.I want to concatenate each line into one long string for parsing The below line of code is not working: datajoined =dataline.Insert(datajoined.Length - 1, dataline.Length - 1)My inevitable goal here is to track stream data with a progress bar. But first I must learn to dload page data in chunks.

I'm trying to setup a simple app that reads a file and then writes the contents to another file using OpenFileDialog and SaveFileDialog. Looking at the debbugger it looks like it's reading fine, I can see the data I want written. Towards the end of my code I get the following error message:"Illegal characters in path". I've researched this error. I'm not using any illegal characters such as /\? etc and the pathname contains all alpha characters. I'm pulling the test file from the C drive and trying to save it there as well.

I am trying to make my application read data from a file. Then save the data back. However I keep getting an error which says the file is still open so cannot be edited. I also read that there is an issue with the streamreader and streamwriter do not close the program straight away. I was wondering if anyone had a way around this or any alternative ideas. Heres my code so far!

I am new to Visual Basics and I am using Visual Basic 2008 express. I have been using video tutorial on line to learn VB and they are great in explaining what is happening the code vs. just looking at code. I think from what little I can find I would be using StreamWriter WriteLine and StreamReader readLine .I am using a couple of forms. I am looking for simple basic code to use a form as a way of modifying timer intervals and store the values in a single text file on separate lines.
Description:
Form1: will contain the main code that will run. It will contain some timers. I want the timers to look in a text file for their intervals. Each timer would be on a different line.
Example:
Timer1 interval would be located on line 3
Timer2 interval would be located on line 6
Timer3 interval would be located on line 20
Form2: will contain 3 textboxes. This is where when I load form2 I will also read the same values from the text file to preload the text boxes. I will now be able to change the timer intervals as needed and press a button to update the text file. The update button will also reload the new timer settings on Form1. This is very similar to how a CNC Machine works with Parameter settings. This can be useful for storing many different settings for a form that a user can modify and be stored and reloaded next time the program runs.
I have a text file that has different controls for text boxes. This text file controls the BackColor, BorderStyle, Font-Bold, Font-Size, Height, Width, ReadOnly, and TextMode a sample is below:
*****Detail Header
txtDetailHeaderBackColor = Black
txtDetailHeaderBorderStyle = None
txtDetailHeaderFont-Bold = False

s(0)=i
