Writing on USB Flash Memory

[Sobhan.Vezzu]

Hi All,

In our application we have to copy some files onto USB flash memory.

I am not sure on how to achieve this? Any pointers or help would be
appreciated.

Regards

The USB flash memory is like any other drive with a FAT file system, so you
only have to know its unit letter and use the usual functions to write
files.

You can access the USB drive like any other drive. 'FileCopy' can be used
to copy a file to the drive, for example.

Is there a way to tell which one is the USB drive?

I'm not sure if .NET provides that functionality natively. If not, you can
use WMI:

http://vbnet.mvps.org/index.html?code/wmi/win32_diskdrive.htm

Or:

Imports System
Imports System.Management
' Disktypes - NoRoot = 1; Removable = 2; LocalDisk = 3; Network = 4; CD
= 5; RAMDrive = 6;
Public Class Wmis
Public Shared Sub Main()
Dim disks As New ManagementClass("Win32_LogicalDisk")
Dim moc As ManagementObjectCollection = disks.GetInstances()
Dim mo As ManagementObject
For Each mo In moc
Console.WriteLine("Disk type : {0}", mo("DriveType").ToString())
Next mo
disks.Dispose()
End Sub 'Main
End Class

.... or if you do not wand to use WMI you can use p/invoke as shown in:

..NET 2.0 will contain a 'DriveInfo' class which priovides that functionality
natively.
