Monitor file selection in explorer (like clipboard monitoring) in C#
- by Christian
Hi,
I am trying to create a little helper application, one scenario is "file duplication finder". What I want to do is this:
I start my C# .NET app, it gives me an empty list.
Start the normal windows explorer, select a file in some folder
The C# app tells me stuff about this file (e.g. duplicates)
How can I monitor the currently selected file in the "normal" windows explorer instance. Do I have to start the instance using .NET to have a handle of the process. Do I need a handle, or is there some "global hook" I can monitor inside C#. Its a little bit like monitoring the clipboard, but not exactly the same...
Any help is appreciated (if you don't have code, just point me to the right interops, dlls or help pages :-) Thanks, Chris

using SHDocVw;
using Shell32;
public static void ListExplorerWindows()
{
foreach (InternetExplorer ie in new ShellWindowsClass())
DebugExplorerInstance(ie);
}
public static void DebugExplorerInstance(InternetExplorer instance)
{
Debug.WriteLine("DebugExplorerInstance ".PadRight(30, '='));
Debug.WriteLine("FullName " + instance.FullName);
Debug.WriteLine("AdressBar " + instance.AddressBar);
var doc = instance.Document as IShellFolderViewDual ;
if (doc != null)
{
Debug.WriteLine(doc.Folder.Title);
foreach (FolderItem item in doc.SelectedItems())
{
Debug.WriteLine(item.Path);
}
}
}
