DeviceIoControl question
-
RomTibi, I completely understand your problem now. You have a
HANDLEto a physical drive and want to somehow associate that back to the USB device. I spent about 10 minutes looking into this... and I did not find any way to use DeviceIoControl because there are no documented IOCTL codes that will do this. I did not find any documented methods for using a HANDLE to a physical drive for obtaining information about the parent USB device. However... you can absolutely do this using the Windows SetupAPI[^]. You could call the SetupDiGetClassDevs function[^] with the GUID_DEVINTERFACE_DISK class[^] and enumerate all of the storage devices using SetupDiEnumDeviceInterfaces[^] and call the SetupDiGetDeviceInterfaceDetail function[^] to get the drive path and serial. You can then call the CM_Get_Parent function[^] to get the parent USB device and retrieve these details. Please spend some time researching this... if you cannot figure it out let me know and when I have more free time I may be able to write a sample function for you. Best Wishes, -David Delaune:rose:Thank you! I`ll do what you said. Waiting for your answer I found this: http://code.msdn.microsoft.com/CppStorageEnum-90ad5fa9[^] I`ve tested a few, it seem to work, but it is to clean up a lot, maybe to include the dll code in the main. I`ll keep you up to date with my progress. Thanks again! :)

If you can give me some advice I would be gratefull... :(

Thanks! :) I have actually been a member here on codeproject for around 11 years but I forgot the password to my first account and created this one to replace it.

Almost everything can be ported to VC6 with the exception of some of the modern C++ templated code and C++11. What version of the Platform SDK are you using with VC6?

My problem simplified so I posted this http://www.codeproject.com/Messages/4192965/Need-help-to-port-example-in-VS6.aspx[^] because remained still a problem to me. I hope you don`t mind. :)

Hi RomTibi, No I don't mind at all. But I don't think anyone will be able to answer your question because to convert that project to VC6 takes alot of work and patience. You will just need to copy alot of Setup API structs and defines into a new header. If I have some free time this weekend I'll investigate it. Best Wishes, -David Delaune

Hi, Just wanted to drop in and let you know that I have not forgotten about your issue. Unfortunately I was out of town last weekend and did not write any code. I still have it on my TODO list so let me know if you have solved your problem.
