I'm trying to create a shortcut (.lnk) on my windows filesystem.
The code I have is working fine. However, when I run the same console application on a Windows 2008R2 Server, it acts differently.
So I have my console application and here is what happens:
My program simply creates a shortcut on the desktop with a .docx extension and all goes fine on my local machine. When I run the same console application on my Server, it creates the same shortcut but the target got modified... it changed the target to a .doc file.
In other words, when I run the console app:
LocalMachine
Creates MyWordFile.lnk pointing to U:\test.docx
Server
Creates MyWordFile.lnk pointing to U:\test.doc
This is strange behaviour. Here is the code
Code
using System;
using System.IO;
using System.Runtime.InteropServices;
using System.Runtime.InteropServices.ComTypes;
using System.Text;
namespace TestShortcut
{
class Program
{
static void Main(string[] args)
{
//ShortcutTarget
var sTarget = @"U:\test.docx";
//ShortCutName
var sName = @"MyWordFile.lnk";
IShellLink link = (IShellLink)new ShellLink();
link.SetPath(sTarget);
IPersistFile file = (IPersistFile)link;
string desktopPath = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory);
file.Save(Path.Combine(desktopPath, sName), false);
}
}

internal class ShellLink
{
}

void SetHotkey(short wHotkey);
void GetShowCmd(out int piShowCmd);
void SetShowCmd(int iShowCmd);
void GetIconLocation([Out, MarshalAs(UnmanagedType.LPWStr)] StringBuilder pszIconPath, int cchIconPath, out int piIcon);
void SetIconLocation([MarshalAs(UnmanagedType.LPWStr)] string pszIconPath, int iIcon);
void SetRelativePath([MarshalAs(UnmanagedType.LPWStr)] string pszPathRel, int dwReserved);
void Resolve(IntPtr hwnd, int fFlags);
void SetPath([MarshalAs(UnmanagedType.LPWStr)] string pszFile);
}
}
Update
I noticed that the 4th character gets removed from the target's extension. So, when i have a file "file.abcdef", the link points at "file.abc". Also spaces get replaced for underscores, so "my file.abcd" pointer becomes "my_file.abc"
