How to obtain the linked pathname in a LNK file ?
Peter Wagner
How can I get this pathname?
There's a :NET method or a WIN API function?
TIA

You can definitely get the pathname, although doing it the correct way
is going to require some work.
LNK files are loaded and accessed through the IShellLink interface.
However, to get to this interface, you need to create a COM object (with
CLSID CLSID_ShellLink). Once you have this, you need to get the
IPersistFile interface, and call the Load method using the path to the link.
Once this call succeeds, you can then use the IShellLink interface and call
the GetPath method to get the path to the linked file.
Of course, this is how to do it in COM. There is no way to do it off
the bat in .NET, but you can definitely use COM interop to access this
information. It's just a matter of creating the definitions.
If you need more help, let me know.

Try this:
using System.Management;
using System;
public class WMITester {
static void Main()
{
// Using ManagementObjectSearcher class
const string FileName = "Address Book";
ManagementObjectSearcher query = new ManagementObjectSearcher(
"SELECT * FROM Win32_ShortCutfile WHERE FileName=" + "\"" + FileName + "\"");
ManagementObjectCollection queryCollection = query.Get();
foreach( ManagementObject mo in queryCollection )
{
Console.WriteLine( "Name '{0}' :Path: ‘{1}’ :Target '{2} ",mo["Name"], mo["Path"], mo["Target"]);
}
}
}

Oooh, very complicated?!
There's no structure definition of a LNK file?
Perhaps how much the offset to the begin of the linked file is or so?!

There's a 'UCOMIPersistFile Interface' in .NET.
But w/o sample code I can't work with COM this interface.
In the MSDN Library I've found:
-Q130698
-"Using Shell Links in Windows 95"

Thank you very much !!
That's verrrrrrrrry good.
You're the WMI specialist.
For you it's very simple. ,-)
I'll and should study the Management namespace classes.

An other question at the WMI specialist. ,-)
It's possible to do a Shutdown using the Management namespace classes too?
Perhaps with the Win32Shutdown Method in Class Win32_OperatingSystem ?
And to detect a RAS connection/disconnection too?
If so, please can you give me an advice how to code it?
Unfortunatelly there's little documentation about Management namespace in
VS.NET and .NET Framework Beta2. :-(
TIA

using System;
using System.Management;
using System.Runtime.InteropServices;
// Shutdown a system using WMI (management classes)
public class Tester{
public static void Main() {
ManagementObject o;
ManagementPath path = new ManagementPath( );
path.Server = "."; // . for local server, else remote server name here.
path.NamespacePath = @"root\CIMV2";
// check your boot.ini file for the correct operating system entry & boot partition
// this sample is for XP installed on partition1
path.RelativePath = @"Win32_OperatingSystem.Name=""Microsoft Windows XP
Professional|C:\\WINNT|\\Device\\Harddisk0\\Partition1""";
o = new ManagementObject(path);
bool EnablePrivileges = o.Scope.Options.EnablePrivileges; // set required privileges
o.Scope.Options.EnablePrivileges = true;
// Invoke method (shutdown or reboot)
ManagementBaseObject outParams = o.InvokeMethod("Shutdown", null, null);
o.Scope.Options.EnablePrivileges = EnablePrivileges; // restore privs (optional)
}
}
For your second question I need some time to look at on a server running RAS.

I've found this in the Documentation:
".NET Framework Tools: Management Strongly Typed Class Generator
(Mgmtclassgen.exe)".
But I think you know about the 'Mgmtclassgen.exe'.

Willy Denoyette
Yes, I know about it ... and some bugs it generates :-)),
But it's indeed a good tool to start with.
Thanks anyway,
Willy.

Hi Willy
Thank you very much for this very good solution.

For local servers the server name is necessary too.

Is "root\CIMV2" on every NT, Win2000 and XP system the _same_ ?
Where is this string defined?
I've got Beta2 and there is "ManagementPath.DefaultPath Property" declared.
Has MS forgotten to delete this Property in the Beta2 Documentation; was it
included in Beta1?

On using the System.Management namespace I don't like such strings.
That's very 'shaky'.
But probably it's because based on WMI ?!

Yes please.
Don't forget it !! ,-)

For the local server you can use "." or the machine name.
The namespace path is the same for all OS supporting WMI.
If you want to bind to the local servers namespace root\cimv2 you could use the DefaultPath property:
ManagementObject o;
ManagementPath path = ManagementPath.DefaultPath;
path.RelativePath=@"win32_OperatingSystem........
The strings you call "shaky", are an absolutely requirement, how would you otherwise indicate what action should be performed?
Your Q about RAS, what exactly would you like to retrieve... (physical connection or logical session establishment or both).

On my machine "." doesn't works ->Exception.

OK.

Are you shure?!
I'll check it.

I would say, I prefer functions/methods w/o string parameters like API
calls.

Only two things first.
The beginn and the end of the RAS connection.
Beginn = connect with the provider (the tax counter begins to count)
End = disconnect from the provider (the counter was stopped)
