WMI To Get Drive Letter Association With Physical Drive Path Misses CDROMs?
Feb 19, 2012I'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?

Dim query As New System.Management.ObjectQuery("select * from Win32_LogicalDisk")
Using searcher As New System.Management.ManagementObjectSearcher(Query)
'loops for all drives on system
For Each Mgmt As System.Management.ManagementObject In searcher.Get()
And it was working but now it is giving error. Below is error with stack trace

at System.Management.ManagementObjectSearcher.Get()
I also want to know alternative way to get unc path of drive that is also not depend on windows API. As there is a class driveinfo to get all drives (including network) on system. Is there any class that also provide complete or unc path information of Drive.
C# - Determine A Mapped Drive's Actual Path?
Jan 14, 2010How do I determine a mapped drive's actual path?
So if I have a mapped drive on a machine called "Z" how can I using .NET determine the machine and path for the mapped folder?
The code can assume it's running on the machine with the mapped drive.
I looked at Path, Directory, FileInfo objects, but can't seem to find anything.
I also looked for existing questions, but could not find what I'm looking for.

Accessing Files Off Of A Drive That Has A Different Path From System To System?
Mar 26, 2011I'm coding this neat little project that's kind of a hack into the SanDisk U3 Cruzer's ability to have both a CDFS and FAT32 File System. This is helpful because the program is burned to the CDFS (It's basically slip streamed as an .ISO in place of the original U3 .ISO), and the settings files (which I've developed as text files) are placed on the root of the flash drive. The program itself is VERY simple actually, except I'm having a slight issue that's really driving me insane:
The drive path of the Flash Drive won't be the same from computer to computer. I.E... The files are "UAI.txt" and "UInfo.txt". The root of the drive on my comp is "I:", but on my laptop is "F:". So if I program the path from my computer as the absolute path, an exception is thrown when the path changes on another computer. I cannot have this happen. It is probably THE MOST crucial element to this program. How can you save and read info if you can't find the files? =P
So I've gone through so many threads and forums trying to find a batch of code to allow me to make the path relative. I've found the following code (modified, of course). It works PERFECT in Debug, but throws an exception once packaged to the CDFS partition:

Finding Physical Drive Number Using Drive Letter?
Jun 16, 2009I 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.

View 1 RepliesGetting Physical Drive Number From Drive Letter?
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. 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.

Jun 16, 2009I 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.
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?

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?

Interface And Graphics :: Drawing Dotted Path Lines, With Even Dots Along The Path Line?
Apr 13, 2012Problem drawing dotted path lines, with even dots along the path line.I want to draw a path line that can be any shape (square, round, outline etc), and along this path line I want even dots to appear.
I also want to be able to resize the shape (as in the example attached)This is very easy to do using "DrawPath" and defining points for the path and using a pen defined as dots.The problem I have is I want the dots to be evenly placed along the path, on any shape or size I draw.In the example I have created, I create a square with 4 points and draw a dotted path.There are 2 buttons that allows me to resize the square (larger or smaller) this helps show the problem more clearly.
The path starts at the top left corner and finishes back at the top left corner, the dots are evenly placed along the path, except the final dots at the end of the path. (Sometimes the dots are even and other times they are not even).The shapes I want to draw can be any size and any shape, but I have used a square in this example to show the problem I have. point me in the direction I need to go that allows me to draw the dots and give the impression that they are even all along the path, for all shapes and sizes.
In the pictures below if you change the size of the shape, one will have even looking dots, the other will not.
