Access device manager through labview

[sathish.deena@hcl.in]

Hai All,

I want to build application to identify the USB devices connected to the PC.  I used to achieve this by using devmgr.dll, but i could not succeed.

So if any one knows how to do this means, please share it.

Thanks in Advance.

Did you try the registry listing as I suggested in your original post?

Thanks for your prompt response.

yes, off course!! But I could not find the device which i have connected with the PC.  Thats why i tried to access the same through device manager.  Please help me if you have any soloution.

In the future, please stick to the original post because you're not asking anything new, and it benefits others to see the history.

What have you tried so far, and what exactly "doesn't work"?

Rather than messing around with that DLL, I would suggest using devcon instead. You can call it using System Exec.

O..Sure.  First i tired to get the required information through the Reistry key as you suggest.  But under the USB tree, i found more that 20 sub trees and no one of it hold the information about the USB device (Code warrior) which i have connected. After that I tried to access through devmgr.dll, and tried its different functions to get the required info.  But i am not sure which function i have to use to fetch the information.

I think devcon is going to be easier for you to use. Try it. For example, the command "devcon find usb\*" lists the USB devices. The command "devcon find *" lists ALL devices.

smercurio,
yet again you add another tool to my toolbox.  I think I am going to have to get a bigger one!
Thank you Sir!

Can't take full credit for knowing about that utility. In this thread I suggested using that utility, and I indicated in that thread the original thread where I found out about that utility.

Thank you Sir.
