How di I add a "Send To..." item

[Adrian Hall]

I'm sure this is totally documented and I am just looking / searching for the wrong things here - if some kind soul can point me to the right documentation, then I'm sure I can work it out for myself. I want to add a new element to the Windows Explorer "Send To..." - call it "Send To->Webmail Recipient" - what it will do is parcel up the files that have been highlighted and present a (C#) form that will ask for a recipient and then send those files via my webmail system to the recipient. Can someone point me in the right direction? -Adrian

This article looks helpful[^].

I thought so too - however, the article pointed to shows you how to add a "Send To" menu item to your own application, not how to add a menu item to the "Send To" menu. -Adrian

I thought there were interesting stuff in the code itself, but anyway. A SendTo handler is a COM object which implements the IDropHandler interface. Mike dunn has written an article[^] about how to do this using C++/ATL. Now for C#, the basic start is to implement the IDropHandler interface using the appropriate attributes. A good start is COMInteropPart2\CSharpServer from the VS.NET sample cds. It goes like this :

// CSharpServer.cs
// compile with: /target:library
// post-build command: regasm CSharpServer.dll /tlb:CSharpServer.tlb

using System;
using System.Runtime.InteropServices;
namespace CSharpServer
{
// Since the .NET Framework interface and coclass have to behave as
// COM objects, we have to give them guids.
