I thought you could use a structure as a container. I have line_1 with a line of data read in from a file. I only want to Look in position 1 of the line and position 8 for 9 and position 31 for 11. If I create a line_2 with the parts broken out for pieces that I want to look at then I could use a with statement right?

I'm making a program which has 7 textboxes. I intend the program to be used for classes in school, so the text would be like 2D Art, Geology etc... whatever your classes are. I have figured out how to use the streamwriter to take the text in the textboxes and write them to a .txt file however, my issue is with loading the text from the .txt file back into the textboxes. I did figure out how to write it so that all the text in the .txt file is loaded back into textbox1 but I have 7 textboxes... Here's the coding for the Load button:
Private Sub Button46_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button46.Click
Dim MainWindowLog As String = "V:Users(O.o)~(--_--)~(o.O)DocumentsVisual Studio

I'm trying to read an .rtf file one line at a time but I'm clearly missing something!The file contains 3 lines and I want each line to end-up in a different RichTextBox, so:
Open File
RichTextBox1 = 1st Line in File
RichTextBox2 = 2nd Line in File
RichTextBox3 = 3rd Line in File
Close File
What am I not understanding? I've tried using LoadFile to load the whole file into another RichTextBox first as I got the impression that RichTextBoxes are indexed - but what I got was strings not .rtf format. I've also looked to see if there's an equivalent of the text-centric ".ReadLine" and nothing seems to fit the bill.

Alright this is what im working with. Im Working with vb.net 2003.I have (X) amount txt files in "C:Marble".In each txt files there are 3 lines.I want to read the first line of each txt file and display them in a listbox. [code] Things i need to Find:
-1 How to tell how many files are in a folder
-2 How to create a loop were it reads the first line of each file in that folder
i know i have to use a loop to get each line of the textbox onto a newline of a textfile but i dont know how to figure out how many lines of text the user has entered into a textbox. I tryed using a try statment to loop until it errors, it seems to work sometimes but other times it only takes half of the textbox and adds it to the textfile. And if atmaweapon reads this, i tryed to make better names for variables. Here is my code,
Code:
Path = ("Meals" & ComboBox1.SelectedItem & "" & TextBox1.Text & ".txt")
File = New System.IO.StreamWriter(Path)
If ComboBox2.SelectedItem = "1" Then

how many line of text there are... im not so shure how good it is to run a loop tell it errors for a textfile, but its the only way i could think of.
I am in the process (slow process) if learning vb.net by trying to create a simple application that will read and write (save) chosen information to a text file. The application has text boxes (name, email address, etc) and I want to read information from certain lines in the text and place in the given text box.
Code:
Dim StreamToDisplay As StreamReader
StreamToDisplay = New StreamReader("C: esting estfile.txt")
TextBox1.Text = StreamToDisplay.ReadLine()
StreamToDisplay.Close()
Currently it's reading the first line of text (which is "[username]").
Text file (testfile.txt) is attached
I am trying to figure out how to replace text in a text file on a specific line number. (for testing, line number 4).

I've got an application that passes commands to a terminal window and saves all the output to a text file Here is one of the commands my application passes to the terminal

The output of which is
"HostA has address Y.Y.Y.Y"
this along with a whole bunch of other text is saved to a text file...my question is how do I find the sting "HostA has address Y.Y.Y.Y" in that text file and then extract the IP address and assign it as a string variable?

im working on a small application that lets you input a phone number with "-" hyphens, and then copy that number to a label control minus the hyphens. So for instance 111-234-567 would become 111234567, i have accomplished this using the string.
replace command, however i was wandering if it would be possible to iterate through the string with a for next loop looking for the hyphens and then removing them with the string.
remove command, ive spent nearly 5 hrs trying to get the code to work, but to no avail, no errors are being thrown up, but the hyphens still display along with the number, i am currently teaching myself, and its a sloooooooow process. here is my unsucessful code

This is probably quite a simple question, but I can't remember how to do it off hand.I have an e-mail address of "foo@bar.com".I want to grab the @ and everything after it and then I'll be adding a prefix to the front of the address as I go.
I'm just wonderng how I get hold of the @bar.com from the string?
I know I should know how to do this as this is a really simple operation.

I'm suppose to end up with a label box with my name spelled out in it using string manipulation. This is suppose to happen using the concatenated string to output the name into the label box. I don't have any error codes but I also don't have my name in the label either. [code] "Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. [code]
View 2 RepliesSo I have a string "New". What is the simplest way to convert that string to "New". Basically right now I'm doing this:
Case "NEW"
makes = connector.GetMakesByYear(_AuthorizationKey, "NewCar", CDate(Now), Year)
Case "USED"
makes = connector.GetMakesByYear(_AuthorizationKey, "UsedCar", CDate(Now), Year)
And I would prefer not to use a case statement because it's only one parameter that needs to change, and both are appended with "Car".
The idea is simple, if I have a string value "ABCD" then with a ButtonClick event it should randomly reveal a char while others are hidden. i.e, "B*" another click would "AB**" and so on. So far, my I have been stuck in a for loop.
