View 1 RepliesProgrammatically Eject And Retract CD Drive In Program Or C#?
Sep 19, 2009Is there any way to do so? I know its possible to programmatically eject/retract the cd drive SOMEHOW, cause Roxio does that when it prompts me to insert a disk.
Either c# or vb.net is preferable, but c and c++ are okay too as a last resort.
I am nearly positive there is some way to do this, I just don't know the methods to call.

View 13 RepliesHow To Handle Eject Key
Jul 27, 2010my computer model has an eject key on top of it (touch sensitive), this handles the CD ejecting. But Windows doesn't native support this button, and I have to use Dell QuickSet to use this button (otherwise it does nothing). I need to hook onto this key and eject the CD Drive when it is pressed (I already have the ejecting and the hooking done). But I have no idea how to detect this key? There is no key in the key list for VB.NET, and I don't know what the eject button sends (Numerical wise) so I can't handle it that way. Does anybody know how to handle the eject key?
View 2 RepliesEject USB Disks And CM_Request_Device_Eject?
Aug 5, 2010i have been looking for a way for my application to 'safely remove hardware' or to eject the USB key specified, the application detects the removal and arrival of new devices but i am stuck on being able to eject them. So far my research has lead me to using setupapi.dll and CM_Request_Device_Eject and i have declared
Private Declare Function CM_Request_Device_Eject Lib "setupapi.dll" Alias "CM_Request_Device_EjectW" (ByVal dnDevInst As IntPtr, _ ByRef pVetoType As PNP_VETO_TYPE, ByVal pszVetoName As IntPtr,ByVal ulNameLength As Integer, ByVal ulFlags As Integer)
As Integer I usually code in asp for web application and have no idea how to use these types of unmanaged functions I made my function that takes the drive letter to eject by parameter
Public Function EjectDevice(USBDriveLetter as string) As Integer
'TODO USE CM_Request_Device_Eject() to eject the drive
End Function
I found pinvoke.net: cm_request_device_eject (setupapi) this info on pinvoke for CM_Request_Device_Eject() but i am clueless on how it works and the vb.net section looks portly documented...
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?
Code:
ComputerName = "."

("winmgmts:{impersonationLevel=Impersonate}!//" & ComputerName)
Set wmiDiskDrives = wmiServices.ExecQuery _

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.

Dec 18, 2010The 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.

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?
Detect CD Drive Regardless Of Drive Letter?
Jan 2, 2010I 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)

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)
