Thanks for the link. It's really interesting. The results for digitalWrite seems to match. :) 224 writes per millisecond gives 4.5 microseconds per digitalWrite. With direct port read, the bitRead is

Forum Message 21 Aug 2012  
I just tested it on Windows 7 (home premium 64 bit) and it works. I imported the project to Visual C# 2010 Express first, so this could be one reason - maybe it does not work if built with older ver

Thanks for sharing your fix! I will probably soon need it in my program.

Thanks. Sorry I don't write any line numbers ;) - there would be lot of them and this is not a modification you can do without understanding the code at least quite a bit. If you look into the Driv

Hello, If after you insert the card you can see the disks in Windows Explorer, then DriveDetector should detect them. It's possible that the disks are not considered "removable" by Windows and Driv

Hi GM, Thanks. Sorry, but I don't know much USB devices; haven't even heard about Unmounted volumes before. All I can recommend is to look at MSDN into the documentation for WM_DEVICECHANGE:

Hi and Thanks! I don't know if there is any unique ID of flash drive, but don't think so. Even if there would be, it would probably be possible to change it, same as you can change it for hard dri

Yes, feel free to use it in any project in any way.

I am glad that the code is useful. Now I see what you mean, there really is the "Eject" command. As for helping I thought I already did by writing that the previous post. ;) The "Eject" or "Uninsta

Hi, If the same drive is detected when using the system tray icon but not using the my computer way, the only reason I can think of is that Windows do not send the notification message. Or it sends

The code does not detect devices which are not volumes (which do not show up in Windows Explorer as a drive). Please see the earlier post "How to detect USB device removal?" for solution.

Sorry, what I wrote above is all I know about this. :) Perhaps someone who already solved this will post his result...

Sorry, I didn't try the code and thought about the DriveType as a flag. You're right. It's either Removable or CDRom.
Forum Message 30 Mar 2008  
It should be possible to filter out CD and DVD's using DriveInfo. For example, in the DeviceArrived event handler you could use code like this: private void OnDriveArrived(object sender, DriveDetec

The easiest way would probably be to use the "native" NET framework way of detecting device changes - please see the post here from March 31 2007. It uses WqlEventQuery. I didn't try it myself but it

Hi, Sure I will be interested in the version with support for multiple devices. You are right about the mDeviceNotifyHandle and other variables being overwritten. There needs to be array instead of

Hi Yosi, Thanks. I think this problem may occur by combination of 2 factors: 1) DriveDetector is able to monitor only one device. If you register multiple devices (as you write: "calling Regist

I seems unlikely to me that some antivirus program would or could prevent windows from sending the message. Please note that the sample program only works with mass storage USB devices - those which a
