Get the path of the shortcut used to launch the exe rather than the exe path itself

If a user launches my application from a shortcut how do I get the path of the shortcut that was used to execute the application? It's easy enough to get the directory of the application itself. All of the following provide useful information:
Directory.GetCurrentDirectory();
Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().CodeBase);
Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location);
Path.GetDirectoryName(Environment.GetCommandLineArgs()[0]);

Open in new window

However, let's say that my executable is on a share, let's say the path is \\MyServer\D\SharedFolders\MyApplication\MyExe.exe. Now, let's say the user creates a shortcut in C:\Users\[username]\Documents\My Shortcuts\MyExe - Shortcut. If the user double clicks the shortcut all of the above will return the UNC path. Is there a way I can get the path of the actual shortcut that was used to launch the executable?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I don't think this is possible, why would you need the shortcut's location?

Hi Russ,

I am not sure if I would want to spend time in C# to do this. I took an easy way out using Platform Invoke. Please read this link carefully: https://www.pinvoke.net/default.aspx/kernel32/GetStartupInfo.html

Once you are done going through the above link,copy-paste the following code in your App

using System;
using System.Runtime.InteropServices;

namespace CrmXpress.EE.WinForm
{
    class EEHelper
    {
        [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi)]
        public struct STARTUPINFO
        {
            public uint cb;
            public string lpReserved;
            public string lpDesktop;
            public string lpTitle;
            public uint dwX;
            public uint dwY;
            public uint dwXSize;
            public uint dwYSize;
            public uint dwXCountChars;
            public uint dwYCountChars;
            public uint dwFillAttribute;
            public uint dwFlags;
            public ushort wShowWindow;
            public ushort cbReserved2;
            public IntPtr lpReserved2;
            public IntPtr hStdInput;
            public IntPtr hStdOutput;
            public IntPtr hStdError;
        }

        [DllImport("kernel32.dll", SetLastError = true, EntryPoint = "GetStartupInfoA")]
        public static extern void GetStartupInfo(out STARTUPINFO lpStartupInfo);
    }
}

Open in new window


And in your MainForm Constructor/s
public frmMain()
        {
            EEHelper.STARTUPINFO startupInfo;
            EEHelper.GetStartupInfo(out startupInfo);
            MessageBox.Show(startupInfo.lpTitle);

// I did not test this but I think it doesn't matter where do you put this code, it will give you the desired results.
            InitializeComponent();
        }

Open in new window


As this is a PInvoke call I suggest you handle the error appropriately and test it in various situations which you see your end users in before putting this code in a finalize product. It is not that GetStartupInfo is a rogue/risky call but it is always wise to be cautions while making PInvoke calls. Let me know if you have any questions/concerns.

Regards,
Chinmay.
