Hi guys !

Can anyone help me on these two issues

1. Disabling Autoplay for all drives / drive types
2. Catching device removal / arrival Window messages, ie. whenever an USB stick, CD ROM, DVD, printerport, etc. is inserted/mounted or removed, my VDS app gets notified about the type of device arriving and the drive letter or port that it has been mounted on ?

I have found C++ code that tries to do the same in a Windows service - however this appears not to be working.

I can post the C++ code if it is of any help.

Thank you for the reply

I will look into the VDS application you mention.

I have attached the source code.

henrywood,
Have you tried hooking the WM_DEVICECHANGE API message? IMHO the C++ code is a bit overkill just to tell when a device change occurs. If you had a registered copy of GadgetX I have code on my forum that shows how to get a complete list of Devices installed on the PC. I also have code that shows how to get a list of all the running services and their status this includes those that are device drivers. I would still start with trying to hook WM_DEVICECHANGE first and then go from there.

hennrywood,
Also just so you know it is not nessary to use the RegisterDeviceNotification API if you are only interested in Ports, Drive Volume, OEM type of devices.

:WM_DEVICECHANGE

goto EVLOOP

[/vds]

This catches it, however @msgparams(W) is always 7 og @msgparams(L) always 0 both on INSERTION and REMOVAL. Also it would appear that I get more than one notification ?

Maybe it is time to get a copy of GadgetX
I may look into it getting a copy tonight

I am looking to get the drive letter/device type and port name/type for both CD/DVD/USB and PRINTER PORTS

If you can help me achiving this with GadgetX, I would almost certainly be buying a copy of GadgetX

Thank you for your help

Henry,
I guess that your request is enough for me to update the Hooking mechinism in GadgetX the way that I have been wanting too but have not had enough reason to justify the time spent on the update. Wink

Currently with GadgetX you can get the fact that a device was added and removed but because GadgetX does not cache the data that the lParam is pointing too it is unable to tell you what kind of device is being added and removed.

After the updates GadgetX will be able to cache that information. I will keep you posted on the progress.

That sounds great !!

Any idea how long this update will take ? (no pressure ! Wink

)

Henrik,
I have applied the updates to GadgetX. Very Happy

I am currently updating the documentation. As soon as I have the documentation I will upload GadgetX for you to try. I will also include the demo for using the WM_DEVICECHANGE message.

Thank you very much !

I nearly cannot wait !

Henrik,
Get your credit card out Wink

I have posted the updated version of GadgetX. The update includes a demo called DevChange.dsc... Have fun and let me know if you need any help. I am uploading this new version to the registered users area of my web site as well.

Hi dragonsphere !

I have looked at your DEVCHANGE example included with the new GadgetX and I have a couple of questions:

1. How would I also read the volume name (ie. E: or a portname) on arrival/removal ?

2. How would I read the description/name of the device (USB Kingston etc.)

Also, would I be right in assuming that the example will only notify of USB devices since you have this line ?

%%hDevNotify = @RegisterDeviceNotification(%%Main,@Get(GUID_DEVINTERFACE_USB_DEVICE))

in the code. If so, then how do I change it so any kind of device would be catched ?

I haven't looked too closely at the example yet, since I am not too familar with the GadgetX syntax.

Hi Henrik,
Here are the answers to some of your questions...

1. How would I also read the volume name (ie. E: or a portname) on arrival/removal ?

Ans. I have examples on my Message board that show how to grab info about a device that you can add to this demo.

2. How would I read the description/name of the device (USB Kingston etc.)

Ans. See the answer for number 1.

3. Also, would I be right in assuming that the example will only notify of USB devices since you have this line ?

%%hDevNotify = @RegisterDeviceNotification(%%Main,@Get(GUID_DEVINTERFACE_USB_DEVICE))

in the code.

Ans. No, that line only adds the USB device type however I have no devices on my systems that fall into this type. When testing this demo if I added any type of USB drive Windows reports that I am adding a volume device type. Look at the WNDPROCEVENT it has a IF statement that captures Volume, Port, OEM, USB, and Handle types of devices. The WM_DEVICECHANGE only captures device type changes. It does not report the common names for the devices. Please see Ans. 1.

4. If so, then how do I change it so any kind of device would be catched ?

Ans. There is another Constant for Windows XP and above that is supposed to register your dialog with all device types. The name of the constant is DEVICE_NOTIFY_ALL_INTERFACE_CLASSES and has been defined in the demo. However I have not quite figured out how to use this yet. I am still researching this.

I haven't looked too closely at the example yet, since I am not too familar with the GadgetX syntax

Ans. That is why I am here. You should have received an email invite with your registration information for GadgetX sent approx. May 07,2007 9:00AM Eastern Time. Please direct all other questions to my message board so I can personally and better assist you.
