Making A VB Application Which Chooses A Random Line For A File?
Nov 15, 2011
making a VB application which chooses a random line for a file, sets it as the value of a Label (word) and also adds it to a ListBox (list) when a Button (nextbut) is pressed. I also want it to keep going.
Button; Text: Next
Name: nextbut
Label; Name: word
Listbox;Name: list
What i need it to do is to load a line from a file ("C:words.txt" for example) and set it as the value f the label. The lines are different lenghts.

Iw ould like to know how to make it so every time you click on a button a different outcome can happen from the opens i gave the application.such as: when i click button 1.i will want it to either close the application or show a textbox but the outcome should be random out of the two.Like a dice if you get 1, 2, 3 the application will execute command "Me.close()" but if it rolls 4, 5, 6 it will execute the command "textbox1. show()"

If the user chooses to save over an existing file, I want to essentially delete the file first, then re-create it and save to it. Basically, I don't want to append to the file. I want to completely overwrite. However, I am just running into all these snags. It basially deletes the file as soon as the savefiledialog box opens. before, it would simply append. [code]

I 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...

I am quite puzzled here. I have a program inwhich when the user clicks on the command button, a random line should appear but only once. I am storing each line with different variables. Right now i have the random line coming up but it is repeating itself. For instance, when i click on the button, line 1 appear, then line 4, and them line 1 again. How can i stop the line 1 to show again?

I have a label that reads a random line from a text file and that string becomes the text for the label.
Now the problem; the label will only work if it is clicked because the event handler is click.What I need is this to work automatically at startup. In other words, it should change the label's text to the random string of the text file on startup of the application.
Here is my code.[code..]

I'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.
Imports System.IO
Dim I as Integer
Dim LineText as String

When i am receiving server responses some are to long for the RTB so obviously continue on the next line. Each line is time stamped. If the word is to long it looks as follows:
15:00 this is a long
message
15:01 another message and so on
what i would like is for the new line to be indented to under the text above so it does not wrap directly under the time stamp. [Code]
