Using For Each Loops To Different Lines In A Textbox
Feb 24, 2012
I am trying to create a For Each Loop in my program.
I have 20 lines worth of data in my RichTextBox, and I want to apply a ruleset as follows:
If Textbox1.Text.Contains(Printer(13))
Then ClassifyTextbox.Text = "Printer - Jam"
ElseIf Textbox1.Text.Contains(Printer(9)) Then ClassifyTextBox.Text = "Printer - Toner"
ElseIf Textbox1.Text.Contains(Printer(i)) Then ClassifyTextBox.Text = "Printer"
The 20 lines I have are IT related issues, e.g 'The printer has a paper jam' The Classify Textbox displays the class the issue relates to, then I have some code to send it to a text file for storage.
Each of the 20 lines are different classes, For Each Loop statement to read the first issue classify it send it, then repeat 20 times, so that my text file has 20 rows of data, but each issue has been classified due to my ruleset in the code above?

how to count the lines in textbox1.text (with multiplelines). I don't need to count each character. I only need to count each line from top to bottom in textbox1.text (multiplelines) and I will use Label1 to display the numbers.
example:
1-pauljaones
2-tommyperrry
3-marktoms
4-Jonessmith
5-paulwhite
Obviously this is 5 lines and that's what I need to count.

I have a sub which creates an XML file but the thing is, all the parameters are 'hardcoded', so I decided to give some inputs so each data in each node is customizable. Now, I would like a loop to read the text in textbox1 and assign that to variable one, do the same for textbox2, write the node, loop again (using the same variable) and assign that variable a value in textbox3 and write the node.
I can while loop to write nodes, but only for fixed data or data with 500000 variables for each loop. Is there any way to do this such that on each loop it dynamically sources the variables data from the 'next text box'. i.e. One first loop uses textbox1, second loop it knows it has used textbox1 .'. it uses textbox2 etc... Is there a way to do the same thing but write back to text boxes in an order, knowing what was previously written.

the purpose of the program is to display the monthly payments on the loan.My homework is to use do while loops instead of for loop.Here is the code for the for loop.
Option Explicit On
Option Strict On
Option Infer Off

Now I'm having some trouble displaying the output using the do while loop, and I'm pretty sure it's a loop problem on my code. However, I cannot seemed to find out what's wrong. I looked at the examples of do while loop in my textbook, but I couldn't find anything useful to my problems of my program.This is the output for the do while loop.
Here's the do while loop code
Option Explicit On
Option Strict On
Option Infer Off

When I use a For loop in a For loop the Contains Statement dosen't work! Even my custom one! I even tested mine and it works 100% And neither that or the String.Contains function work inside of For Loops And, I know both of them use loops to search through a string.
My function(It will atleast search once):
Function RealContains(ByVal load As String, ByVal needle As String) As Boolean
load = load.ToLower

i've got my basic AutoTyper ready (well and one with autoupdating etc in it) but it's only a singular line. [Code] What I want to do it to type multiple lines, I know I'll have to enable multiline on the TextBox. I want it to type one line per time interval using 1 timer. I don't know how but I know it would have to count the lines but from then on I'm stuck. I will need to make it type line 1, then on the next loop line 2 and go on until it's reached the amount of lines from the count then repeat from line 1. [Code]

I am using Visual Basic 2010 with Windows 7. My code is is follows:
Dim file as system.IO.StreamReader
file = My.Computer.FileSystem.OpenTextFileReader(C":financialsprogramcurrency.txt")
TextBox1.text=file.ReadLine()
file.Close
For some reason my program does not execute beyond the Dim statement and instead displays the form without text in TextBox1.

I was trying back yesterday to count the visible lines in a textbox, which is multiline, and found this article: [URL] but... it didn't work... The code worked fine, but sometimes it returned like, 5 or 4, when I counted the visible lines, and there was 2.. If you know what's wrong/have any answer for this it would be nice :)

What I am trying to do is remove lines of a multiline TextBox based on certain criteria, such as the number of characters or words. For example, if I paste a list of phrases into the TextBox, I want to remove all phrases that contain more than 25 characters. Once the phrases are removed, I then want to remove the empty lines that are left behind, but I have commented out the ".Replace(vbCrLf & vbCrLf, vbCrLf)" for the sake of making the results easier to follow (see screenshot from Excel below, which includes a blank cell wherever a phrase has been removed).
Here is my
Private Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click
Dim lines() As String = TextBox1.Text.Split(vbCrLf)
[Code]....
Why is it not "blanking" the entire line in ALL cases where the line contains more than 25 characters?
