Correctly Encoding ByteArray And Sending To Host Program
Jul 17, 2009I am transmitting data over an IP socket and receiving the data via a second program I have written. The server was in VB6 and am now creating a new one in vb.net to run as a service. The major issue I am having is related to the encoding features.
Issue 1 to be able to correctly encode a bytearray so that when it is received by a VB6 program via winsock that the data will be in the proper ANSI format for the pc to read it correctly. So far this works on some files and not on others depending on the content of the file.
Issue 2 to be able to correctly encode a bytearray, send it to a vb.net host program and correctly [decode?] write it to disk.
To make things a little more complicated I must also be able to do this where the client resides on a Windows Mobile, Windows CE, or Windows PC. I have been running some tests and have gotten mixed results.

Jun 17, 2009I 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.

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.

Forms :: Determine A Dynamic Drive Letter For A Directory On The Removable Drive And Then Open That Directory In An Explorer Window
Feb 19, 2009First 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.

Check If Logical Drive Is CD/DVD Drive
Jun 16, 2009Is it possible to check if a Logical device gathered through a WMI search request is a CD/DVD Drive? Right now, I can get the path of every Win32_LogicalDisk through WMI, but E: (for me) is my DVD drive and unless there is a disc, my program fails because it tries to count the number of folders/files on the disc.
Ultimately, I'd like to be able to tell if it is a CD/DVD drive then check to see if there is a disc there before I do anything else to it. Can it be done using WMI?
