Greetings,

I am trying to make a custom download manager in c#. The code compile, I
register it with gacutil and regasm, but when I open IE and click on a link
to download, I get the standard IE download dialog. Is there something I'm
missing? I am new to COM, so any help would be appreciated. Here is my
complete code:

/* BEGIN CODE */
using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;
using System.Windows.Forms;

namespace MyDownloader
{
[ComImport, GuidAttribute("988934A4-064B-11D3-BB80-00104B35E7F9"),
InterfaceTypeAttribute(ComInterfaceType.InterfaceI sIUnknown),
ComVisible(false)]
public interface IDownloadManager
{
void Download(
System.Runtime.InteropServices.ComTypes.IMoniker pmk,
System.Runtime.InteropServices.ComTypes.IBindCtx pbc,
UInt32 dwBindVerb,
Int32 grfBINDF,
IntPtr pBindInfo,
String pszHeaders,
String pszRedir,
UInt32 uiCP
);
}

[ComImport, Guid("988934A4-064B-11D3-BB80-00104B35E7F9")]
public interface Downloader
{
}

[Guid("78BC4A4C-63B7-41CC-B287-858663AF4281"),
ClassInterface(ClassInterfaceType.None)]
public class MainClass : IDownloadManager
{
public MainClass()
{
}

public void Download(
System.Runtime.InteropServices.ComTypes.IMoniker pmk,
System.Runtime.InteropServices.ComTypes.IBindCtx pbc,
UInt32 dwBindVerb,
Int32 grfBINDF,
IntPtr pBindInfo,
String pszHeaders,
String pszRedir,
UInt32 uiCP)
{
MessageBox.Show("Got it!");
}
}
}
/* END CODE */

Thanks,
Kevin

Hi Mattias,

I assumed that regasm did this for me. I had also used regsvcs, but it did
not change the results. Is there some other way to register my control?

Thanks,
Kevin

Hi Mattias,

Perfect! Thanks for your help. There is still one problem, though, which is
a bit strange. For most downloads, this works. But there is a site which
pushes the file bits via an ADO Stream object. In this scenario, IE does not
use the download manager, but instead uses it's built-in. The content type
varies (application/octet-stream, audio/mp3, video/wmv, etc.), and the file
name is set properly in the content disposition.

Do you have any idea about this? Is there another interface I need to
implement in order to catch all downloads?

Thanks,
Kevin

It looks like a specific problem with the Content-Disposition header, and can
be solved with RegisterBindStatusCallback. Any idea about how I would
implement that?

Thanks,
