i want to type in a name to a textbox like type in "Ben" to textbox1. Then i want to click a button and have correlating numbers, say 126 show up in the textbox2. Im using a function to do this, how would i write a function that takes the string in textbox1, goes through each letter and sends back a numerical value for the letter through the function. I know how to do this with text files with stream reader, but don't know how to do this with strings.

I already have a code for detecting a removable device. However, I would like to enable my program to detect that USB drive and read and print the text in that specific text file on my webpage. I also have a program code for reading and printing a text file from a USB but that program needs the drive letter to be specified. My problem is, how would I program if the drive letter is unspecified?
Here is my code by the way,
Code:
<%@ Import NameSpace="System.IO" %>
<%For Each d As System.IO.DriveInfo In My.Computer.FileSystem.Drives
If d.DriveType = DriveType.Removable Then
Dim test As String = File.ReadAllText(& ":\sample.txt")
Response.Write(test)
End If
Next
%>
How to let the string test get the data so that I could put it on my page. I'm currently using that File.ReadAllText method.

I am a vb newbie having some trouble with an assignment. A user enters a letter into a text box, and the output must make the letter uppercase and tell what position the letter is at in the sentence "The quick brown fox jumps over a lazy dog."
Here is my
Private Sub btnSubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSubmit.Click
[CODE]...............
This is what comes out: "A first occurs in position -1". Everything comes out except the position is always displayed as -1.

Is it possible to change to colour of letters as they are typed.I.e
Piece of text says
"Hello World"
when user types "H". The "H" in the original would change if matched and then so on and then when "Hello" is matched it would change to another colour.

I'm a VB beginner.I wonder if it's possible to change the text style letter by letter?I've learned here that you can change the entire style of text like
Dim myStyle As New Font(TextBox1.Font.Name, TextBox1.Font.Size, FontStyle.Regular)
TextBox1.Font = myStyle

I need to write data to a file, preferably in binary format, but I am unaccustomed with the concept. Where's the easiest place to get the basics? I could come here with a specific need, but I'm at the point right now where I am more willing to work within the confines of keeping it simple.
Here's what I know:
1. how to open a new file
2. how to specify the record length
3. how to close the file
Some specific questions:
Does the record length have to be constant throughout the file?
Can I read the nth record without reading the whole file?

Select Case a(b, 3)
Case "d"
c = 0
[Code]....
OK so a(b, 3) has either the letter d,e or f in it but when I try and read the multi dimensional array I don't think it picks anything up

Basically the first letter of a string must be a certain letter. At the moment the only way I know how to do it is as follows:
If sConsignmentNo(0) = "J" Or sConsignmentNo(0) = "C" Or sConsignmentNo(0) = "U" Or sConsignmentNo(0) = "N" Or sConsignmentNo(0) = "H" Or sConsignmentNo(0) = "S" Or sConsignmentNo(0) = "V" Then
Basically listening the same thing out over and over. Is there a way I can say, If sConsignmentNo(0) = ListOfValidEntries i.e J,C,U,N etc?
Using Visual Basic 2008 and cant use regex!

I have a program with 136 textboxes.
I want to be able to take a string that is entered into a textbox, and then put character 1 of the string in Textbox1, char 2 in TB2, char 3 in TB3, etc.
Also, how do I check the length of a string, like strlen in PHP?

So 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".

I want to take a string from a text box and split each letter of the string into an array. Then, I want to take the first item in the array(the first letter of the string)and capitalize it. Once I've done all that, I want to combine the array and convert it back to the original string it was, except I want the first letter to be capitalized(I've already placed this into a variable.)
Here's what I've come up with so far:

In this exmample textData is a string of text and alpha is a single letter a through z or A through Z. I don't need the criteria to be case sensitive, but I do need only the first letter of textData to match alpha. I have tested the LIKE comparator and it does not return all records that begin with alpha.

Here is a sample of my code, its purpose is to convert an input password to a reverse and mirror to match the set password; Ex. If the set Password = "ReWq" then the input should be "QwEr"
The main problem I've encountered is that I can't input a text with less than 11; Ex. "AqWeRtYuIoP" is allowed while "qWer" returns IndexOutOfRangeException Error
Sub Encrypt()
'Subroutine for Mirror and Reverse on Password and ReType
Ch(0) = Pass.Chars(0)

I'm creating a small program using Visual Basic 2010 Express. I'm planning to place the program on a CD, along with the files I want to run. The program will have command buttons, and each button will open a different file.For example, if there is a file on the CD named ReadMe.txt, the user will be able to open it using the program, which is on the same disc as "ReadMe", by clicking the corresponding button (or link) ("ReadMe".)The problem is, that I don't know what the CD drive letter will be. Is there a code to make the program run a file which is in the same location as the program?
