Starting process from .NET app and Attachment Execution Service

Question

I'm using VLC player for playing videos from my WPF app (vlc palyer is distributed with app) It is possible to avoid alert "Open File - Security Warnng" during first start of video (vlc) on new machine without changing system settings?

I'm using this code for starting VLC:

var vlcArgs = string.Format("\"{0}\" --config=\"{1}\" -Incurse --play-and-exit",
   videoFilePath, vlcConfigPath);

var psi = new ProcessStartInfo(@"vlc\vlc.exe", vlcArgs);
VlcProcess = Process.Start(psi);

I found that

Every script or program that is run by using the ShellExecute() API passes through AES

So, if I set UseShellExecute property of ProcessStartInfo object to false, will it help? Or any other idea how to avoid AES check?

Answer 1

Use CreateProcess Instead of ShellExecute. Can you try the below code?

var vlcArgs = string.Format("\"{0}\" --config=\"{1}\" -Incurse --play-and-exit",
   videoFilePath, vlcConfigPath);

var psi = new ProcessStartInfo(@"vlc\vlc.exe", vlcArgs);
psi.UseShellExecute = false;
VlcProcess = Process.Start(psi);

Answer 2

You can try the following :

If proc.StartInfo.UseShellExecute is false, then you are launching the process and can use:

proc.StartInfo.CreateNoWindow = true;

If proc.StartInfo.UseShellExecute is true,

proc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
