Three topics - help greatly appreciated!
-
- How to get a list of all drive letters and names, including USB-memory sticks, eg. "D: Removable drive"? Am I right that every drive has an individual ID-number or name? If so, how to get this name/ID from vb.net? I would like to compare if the two USB sticks are the same when used one after the other in the same USB-port. 2) What code snippet would tell my app to make "foo.exe" start on every Windows log in? 3) Is there an API to compress a folder into a zip-file or is the only way to use some 3rd party command line application?

1 - The System.IO namespace has a class that returns a list of all drives. All drives do have a semi unique ID/name, that would require WMI. They can have a name given to them when formatted, .NET can see that, I suspect most USB drives wouldn't have it. 2 - none, as your app would not be running. Put a shortcut to foo.exe in the run registry key ( I search for runonce, to find it, it's the first one above ), or in the Startup folder of the start menu 3 - are you using .NET 2.0 ? If so, there is zip support in the framework.

You can place a shortcut to your app or that exe in the start menu:
start->all programs->startup. or you can create a value in the registry subkey:HKEY_CURRENTUSER\SOFTWARE\MICROSOFT\WINDOWS\CURRENT VERSION\RUNthat references your program.Posted by The ANZAC

1. Yes, I am using .NET 2.0. How to use this zip support. Could you give me an example code to zip folder and all its subdirectories in "C:\temp\" to folder "D:\here" with the file name "myfold.zip". 2. How to make a registry entry for the startup? Could you give me an example code.

So, what would be the best way to recognize if the inserted USB memory stick / USB hardrive is the same as the one used before?

This is used to detect when someone inserts or removes a USB drive, cd or dvd, provising plug and play is still on. It also tells you what kind of drive is used so I hope this can point you in the right direction or at least allows you to snip bits out.
