calling devcon from inside windows forms not working-CodePudding

The

I've even tried your code C:\\Windows\\System32\\devcon hwids =usb pointing directly at devcon. Also tried \devcon.exe for completeness. The inexplicable error is :

I can see the flipping devcon.exe file sitting right there in the folder! Is there any reason it would not recognise it?

Also, with the command as you wrote it, the log file name is actually named logFileEnablePrt.txt'. I agree that your command looks right, so don't ask me why this happens!

@Panagiotis Kanavos using your code, I get the following error:

This is at the line p.Start();. I tried putting in devcon.exe, and even the whole path (I checked the folder was in my PATH, and it is). Can't get past this. I actually stumbled on that answer you shared and arrived at this brick wall already.

Here is the code works for me, I don't have ports devices so I change it to usb.

public static void Main() { string prodPath = @"c:\devcon\x64"; // Build String string strCmdText = "/c \"cd /d " prodPath " && devcon hwids =usb " " > log.txt \""; // Run command var p = new Process(); var psi = new ProcessStartInfo("CMD.exe", strCmdText); psi.Verb = "runas"; // admin rights p.StartInfo = psi; p.Start(); p.WaitForExit(); }

Worked through a few steps and think I may have an answer...

Just specifying devcon fails as expected...windows cant find the exe as the folder it is in is not in the %PATH% variable in windows..

IF I specify the full path however it works...

It wasnt clear from your original code but if your copy of devcon is sitting in either System32 or Syswow directories you may be hitting an emulation issue as well...

A similar example but with netstat:

EDIT 2::Another example but with devcon:

The target platform here for the build was x64

EDIT3:: With my application build set to x86:
