Eject USB Disks And CM_Request_Device_Eject?
Aug 5, 2010
i 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...

my 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?

Is 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.

I need to write an application that does the following, and I figured it was a good opportunity to write my first VB.Net application:
1. Get the list of fixed disks in the computer
2. For each disk, recurse through all its directories and sub-directories looking for filenames that match a given regex (eg. MyFile.d{3})
3. If found, hash this file to get a unique ID, eg. MD5 (just to check if this file already exists elsewhere)
4. If this file hasn't already been seen elsewhere on the disk, copy it to a central directory

I want to move my programs and the database to another computer and hard-disks. It looks to me as though I nearly have to re-create the controls and rewrite some of the code to make it so the programs still work after the move. At least with ODBC all I would change was the DSN definitions external to the programs. Is there an easy way to move or rename a database without loads of work?
