Detect When Drive Is Ready Or Not?
May 31, 2010
I'm trying to create a Windows Explorer like application, when a flash drive is connected/disconnected the application detects it and does some stuff. This is what I've accomplished so far:
Code:
Private Const WM_DEVICECHANGE As Integer = &H219
Private Const DBT_DEVICEARRIVAL As Integer = &H8000
Private Const DBT_DEVICEREMOVECOMPLETE As Integer = &H8004
[Code]....
One thing that this code does not do is detect when the driver changes from ready to not ready, e.g. if a CD is removed/ inserted into the optical drive or a memory card is removed/inserted into the card reader. How can I accomplish that?

i have a NAS drive that is mapped to my system..My application will copy files to the drive but the only problem is the drive has a sleep function on it therefore when i try to copy files to it and it is in sleep mode, it says the folder does not exist (drive still in my computer but just with a red X on it)is there a function to make ir ready ? the only other way to do it is to double click the drive icon in my computer then it wakes up... but id rather not do this as its a pain.

I would like to detect the insertion, and completion of installation of a USB cable in VB2008 as two separate events. The driver gets installed prior to insertion of the cable.

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)

I am making a program that will allow a user to use any USB flash drive as a key, that when inserted, will automatically (upon validation, of course) enter login and password data into web forms, applications, and maybe even Windows Logon. But first things first: how to I detect when a USB key is inserted into the drive, for instance, perhaps just detect the last/latest inserted drive?
In addition, does anyone know if there is a way to directly identify a flash drive, maybe based on a serial number?, rather than validating it from a file on the device?

I need to detect if a file exists within drive C: but I do not know in advance in which directory it should be located so this means that I have to search the entire disk. Is there a way to perform this process directly (through an existing method for example) or do I have to write code for getting the directory structure and search each directory?

I have made this program in which the user selects a number of directories and copies them all to an external drive. is there a way to detect when the user does something that involves writing data to the hard drive. When they do, I want my application to detect this and back up that file on the external drive as well so that the back up is always up to date.

It might not be the best and i'm currently finishing on adding certain features, commenting it fully and possibly tutorializing it, but if ur needing an object to detect drive connections and disconnections and a lil more, here ya go. This dll is "Events 'R' Us" It also contains some simple public functions - findDrives(driveType) will find on command all of a specific drive type and return a dictionary of values - byteConverter and getMB, getGB, etc..
will convert bytes to larger metric values - getPercentage will simply get percentage of 2 figures and return as decimaland i'll give away more soon, just wanna get this out now, see if anyone has any use for it, almost every thing that can error has an error event and thus far i can only get one to fire (if usb is pushed in and pulled out really fast over and over again, i know where it fires, it's no biggie at moment)

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've been reading about i18n and how to make my app ready for localization. One thing recommended is to set the NeutralResourceLanguageAttribute in the AssemblyInfo.vb file like such: <Assembly: NeutralResourcesLanguageAttribute("en")>However, when I do that I get 'Type is not defined' Anybody have any clues?

i'm making a program that will be used Only from a CD, not ever downloaded to a PC.I just would like to have the user insert the CD into a CD-Rom Drive, and the program will Auto Start with a Splash Screen, then start/load the first windows form. The form will have some buttons on it for the user to interact with the CD, by either going to other window forms or by downloading exe files or zip files to the user's computer.
Also the form has buttons on it for the user to click on to bring up a PDF to be viewed.I have tried to do the Publish and found that it created a setup.exe...as in I think it wantes to install my program, and my program is not for installing. only viewing and interacting with and maybe downloading files from it, my CD program is never to be installed.I'm pretty sure I need to save or create my program as just an AutoRun, that starts when the CD is inserted and that is all I think needs to be done...so how do I just create a AutoRun Only version of my program, not a setup.exe?I will have a ini file to reference the AutoRun file on the CD, no problem.

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.
