I am new to VB and playing with a program to display disk info attached to my PC. I have used WIN32_DiskDrive & WIN32_LogicalDisk to gather info regarding volumes, disks and partitions.
What I want to find how is how to relate the Device Index and Partition # back to a volume (ie with a drive letter).
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.
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.
View 1 RepliesI 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.

View 3 RepliesI have seen numerous dvd playing apps that when you insert the dvd into the drive is displays the movie name. Im looking to implement something like this.

I want to hook the keyboard and make some actions (in vb.net) when a specific physical key is pressed.I have found online several excellent keyboard hook dlls, but there is a problem: the hook dlls find the keycode of the pressed keys, not what physical key is pressed.So, for example, in a USA keyboard if I press the key on the left of the Right-Shif key I see the e.keycode: 191 (OemQuestion), in a italian keyboard I see the e.keycode 189 (OemMinus).This means that if I put in My.Settings the code "189", an italian user can see that has to press the key I want, an USA user see another key to press to have the same action because on it keyboard the OemMinus key is not on the left of the Right-Shift key.now the question is: how to determine univocally the keyboard keys? What do I have to put in My.Settings that determinate a specific physical key, the same for all the keyboard languages?

View 4 RepliesWhat I'm looking to do is 'hook' a physical drive connected to the system so I can process data coming through the API before it's written to the disk. I have a sense DeviceIOControl is where I should be, but I can't seem to find any IOCTL code that uses a callback (which is what I expect I should be using to scan/process data on its way through the API).

View 12 RepliesI am trying to read some data from the MBR using CreateFile, but I cannot get it to work without admin rights. The code I am using is like this:

Is it possible to read data from the MBR without admin rights?
Im writing a program (has been a little while) which will gather files off my computer and make a new partition the right size to store them.I would like this to be automated since it would help if I use it on friends machines.is there a way for me to create a partition from using vb.net and api's etc rather than having to downloading partition manager each time.

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)

View 1 RepliesI am trying to get the HDD Disk Drive information from the DeviceIOControl(,,,,,) function with IOCTL_DISK_GET_DRIVE_LAYOUT_EX control code.
Here are the problems :
1. The DeviceIOControl function returns(as from output buffer) DRIVE_LAYOUT_INFORMATION_EX structure. Which contains some data types i am unable to get. I used. Uint32 instead of Dword. Long instead of Large_Integer.
2. DRIVE_LAYOUT_INFORMATION_EX structure contains a union declaration as mentioned on MSDN , HOW TO GET A UNION in VB.NET or vb 6.
3. Still when i tried declaring the data types as mentioned earlier gives an error (Value does not fall within the expected range.) executing the DeviceIOControl Method.
