Check If Logical Drive Is CD/DVD Drive
Jun 16, 2009
Is 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?

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.

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.

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)

how to open an .exe file from a that is in a certain file, what i am trying to do is create a program that will be portable-via jump drive or cd drive, the reason i feel stupid is that I did not realize that visual basic and vb.net are two different animals- I was trying to use app.path for days- then came across a post that set me straight that I can not use it.[code]

I have created a form that I would like to run from a jump drive, or cd drive, were the drive letter will never be the same-
Application.StartupPath is the answer I have come up with- Implementing it is difficult for me- all the examples I have seen retrieves the path and imports it to a textbox. What I got is a form will start a .exe of a portable program- ( that will be located on the jump drive, or cd)
I have created a form that will -when a button is pressed- execute an .exe to a program that will also be on the jump drive. how to do this from start to finish on how to run an .exe from a file that will not ever be located on the same drive-
I should add I'am using visual studios 2010, visual basic.net

I need to check if the CD drive has a disc inserted, no matter the disc is blank or full.
I tried to get the IO.DriveInfo.IsReady, but a blank disc also return False. Then I tried to get the TotalSize, if there is no disc, it returns an exception tells drive is not ready, and if the disc is blank, it returns function error. How can I determine which error is responsible to the one which no disc is inserted? I should not check the error msg because it will change on different computer of different language.

I have a task and no idea how to tackle it!Basically, I want to disable the CD drive on a PC so our users can't use them.That's how I want to start anyway - ultimately I'd like an icon in the system tray that allows the CD drive(s) to be locked and unlocked providing you know a password.

This is not for school assignment it is for me trying to create a dynamic small application.
I need to run an application from a pen drive. Since different computers call the drive by different letters I need to discover the drive letter and then check for a folder existence. If not there I will make the folder(I know how to manke the file) and ftp from network to the folder then run the items. If it is there I just run the items
My difficulty(probably due to brain freeze) is how to get the drive letter.
