Reading Text File From USB With Unspecified Drive Letter?
Jun 18, 2012
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'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?

i was wondering if there is any way to read from a file in the application directory without specifying the drive letter. Here's what i have:Dim var var = My.Computer.FileSystem.ReadAllText("c:appdirectoryfilename")
If i leave off 'c:' it looks for it in system 32 or something. why can't i just say
ReadAllText("filename")

I'm running the following WMI script to get the associations between drive letters and physical drives on the system, but for some reason it omits CDROMs/DVD-ROMs. Can someone tell me how to get those as well?
Code:
ComputerName = "."
Set wmiServices = GetObject _
("winmgmts:{impersonationLevel=Impersonate}!//" & ComputerName)
Set wmiDiskDrives = wmiServices.ExecQuery _
("SELECT DeviceID FROM Win32_DiskDrive")

I have a program that allows the user to enter a drive letter into a text box. The program then takes the letter and find the physical drive number (i.e. deviceharddisk3..). It then stripes out everything and leaves me with the number 3.
In VB6 I used mDrive.bas from vbAccelerator.com and it worked perfectly. I have been all over the internet and back and cannot find a solution written in VB.NET.

I am trying to get the physical drive (device) number from the drive letter. If the user inputs the drive letter C the program will find the associated physical device number. For example if I input C then the result needs to be \Device\HardDrive1\... Some call it NT Device Name; I think. I have the code for VB6 from vbAccelerator, which works perfectly, but it does not work in VB.NET. My question is there a simple way of pulling the drive info that contains the drive letter and the physical device number. I have searched the internet and found nothing for VB.NET. I would post code but I have nothing for .NET.

I have a program I am converting from VB6 to VB.NET and I am stuck at the very last piece of code. I need to determine what physical device number is associated with the drive letter.
The program takes the drive letter from a text box and goes and finds the device number (i.e. deviceharddrive3...) and strips out everything leaving me with the devicer number; in this case the number 3. I have searched the internet to and fro and found nothing in VB.NET.
My program in VB6 uses a .bas module from vbaccelerator.com called mDrive.bas and works great. I can't figure out how to convert it over to VB.NET.

First off a short background of the project I am working on- I am developing a program that will be run off removable media (i.e. USB Flash drive). This will be a �virtual desktop� which you will be able to take with you and have the same �desktop� on any system. As we know drive letters can change with each host system the drive is plugged into, I need to be able to determine the path for the flash drive and access a specific folder ( i.e. My Documents)
I have an picture box(representing the icon) placed on my form (form1) and when I click the icon I want to be able to open and view the a specific folder from the portable drive. I need a click event that will determine a dynamic drive letter for a directory on the removable drive and then open that directory in an explorer window.

I have a function that copies files from a CD to my HDD:CopyFiles(CD_Drive, FullPath & "")
The problem is that the Drive letter "I:" is not consistent. Sometimes when I connect and disconnect external devices, the CD Drive letter changes and then my code doesn't work unless I open the project, change the letter "I" and recompile.What code can I use that will ALWAYS detect my CD Drive, regardless of the drive letter? (Like for instance, NERO will detect and burn CDs regardless of the drive letter)

I find a lot of VB6 examples out there, and a few C# examples, but no concrete solution in VB.NET. Simply put, I need to get the next available drive letter in as few lines of code as possible.

The drive is connected via USB and the problem I'm having is that, periodically, while my code is executing, the usb drive seems to disconnect and reconnect. (Nothing to do with the program, but the drive itself).I want to find a way to prevent these temporary drive reconnects from interrupting my code. IE, i want to insure that whatever read or write that is requested is actually executed even in the case of a temporary drive interruption.

A customer installed my app (VB 2003) on his server. BUT when he tried to run it, it bombed because the data bases couldn't be found. I hard coded the drive in my app to "C:" and his server is lettered "E". ALSo when it comes time for his client PC's to mapped to his server to run the app, they too will bomb because they see his server as "P:"

Using WMI (and it's code creator) it is easy to find the name of the physical disks on the computer.
vb.net
Dim searcher As New ManagementObjectSearcher("rootCIMV2", "SELECT * FROM Win32_DiskDrive")
For Each queryObj As ManagementObject In searcher.Get()
MessageBox.Show(queryObj("Caption").ToString)
Next
Tried to google how to get the drive letter from each of the disks.

I have made a program that i would like to be able to move from PC to PC; at the moment i would have to change the string directories within the program for each PC i would like top run it on.
By having the user select their drive letter and type their account name into a text box could this be implemented into a directory.
Below is the code, as i was hoping it was coded (lol never is tho).
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim Filename As String = ("*.torrent")

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.

Piece of text says
