reference a windows shell interface using .net 4.0

c#, c#-4.0, windows-shell

Solution

Ok,this is how I got through the problem incase it helps someone

This is how my new code looks like

Type t = Type.GetTypeFromProgID("Shell.Application");

dynamic shell = Activator.CreateInstance(t);

//This is browse through all the items in the folder
var objFolder = shell.NameSpace(@"\\fileshares\Files\test");

foreach (var item in objFolder.Items())
{
    //This is to get the file's comments for each files in the folderitem

    string file_version = objFolder.GetDetailsOf(item, 14).ToString();

     Console.WriteLine(file_version);

}

Problem

I am using the following code to reference a shell dll ``` Type t = Type.GetTypeFromProgID("Shell.Application"); Shell s = (Shell)Activator.CreateInstance(t); Console.WriteLine("success"); Console.ReadLine(); ``` It works fine on my windows 7 development machine.But when I try running the exe on Win 2003 server I get this exception ``` Unable to cast COM object of type 'System.__ComObject' to interface type 'Shell3 2.Shell'. This operation failed because the QueryInterface call on the COM compo nent for the interface with IID '{866738B9-6CF2-4DE8-8767-F794EBE74F4E}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)). ``` I took some help from C#: Referencing a windows shell interface but no luck. I am referencing shell using Microsoft Shell Controls and Automation reference which is Interop.Shell32 dll If someone can guide it will really helpful.
