Program That Generates A Random Line Of Text From A .txt File
Nov 26, 2009I got a little program that generates a random line of text from a .txt file and all is working well, at least for the most part.
On occasion I get an error message popup saying "Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: Index."
Here's my code:

The last bit is where the random number is generated, which I am guessing where the problem itself is, but am unsure as to how to fix it...

VS 2008 Reading Text File Line By Line - Put Into Text Boxes
Sep 21, 2009Basically what I'm trying to do is read a text file line by line. After each line is read, it will put each line into a separate text box. I've been trying to do this for a while and so far I haven't been able to. I tried using a for loop, but that just put all my lines in to one textbox.

VS 2008 How To Read Text File Line By Line

sFileName = "D:UsersArbenDesktopSerieA.txt"
srFileReader = System.IO.File.OpenText(sFileName)

under the code I pasted at the top, but I get the text on line1 in all labels, like all labels become 1, while the text should be 1, 2, 3 and so on. So anyone can help me do that, each label gets the value of the next line in the txt file

View 3 RepliesFCL For A Method That Will Allow To Erase A Line Of Text From A Text File And Replace It With Another Line Of Text
Dec 19, 2008I've been looking through the FCL for a method that will allow me to erase a line of text from a text file and replace it with another line of text. Neither the StreamReader nor StreamWriter have a method for replacing or removing Text from a text file, as does the string object. Are there any available methods for erasing just certain lines of text from a file, and then replacing them with others?
In my code, I'd like to locate a certain line in the text file, and then at that point in the text file, use a For...Next Loop to replace each successive line of the text file with new text:
Dim user_data_file As String = "user_data.txt"
edit_input = New StreamReader(user_data_file)
Dim edit_line As String = edit_input.ReadLine
[CODE]...
However, I can't find any methods that will allow me to do this.

Reading Text File Line By Line, With Resetting Position To Beginning Of File
Jun 23, 2011I'm reading a text file with StreamReader, line by line. If a condition is met, then I do an operation and then start reading the file again from the first line. I realize I could close and then re-open the file, but surely this would be very slow.
I could do this easily in VB6, but pulling my hair out trying to do this in vB.net. It seems that 'Seek' is the function to use, but it doesn't work.
I've seen other examples, where it works, but you must open it a different way -- with a file number.

Comparing Text File Records Line By Line?
May 14, 2009I have to create a new program that reads to Text files. These text files are in the form of a report (with column headings). The purpose is to compare each record line by line to see if their have been any changes made. The record is based on an Account#. Over time these files will be considerably large. What is the best way to do compare records from each file. I'm thinking loading each file into an array and processing them that way.
