How to retrive Outlook message when it has been drop on a form

Hi,

I am working on a application written in C# (.NET 1.1). I have to implement 
functionality that allow users to drag a e-mail from Outlook onto our app. 
Using following code I am able to get e-mail filename but I get null when 
retriving data in "FileContents" structure. Can you help me in retriving 
message content with attachments?

// set up to obtain the FileGroupDescriptor
// and extract the file name
Stream theStream = (Stream) nseDataObject.GetData("FileGroupDescriptor");
byte [] fileGroupDescriptor = new byte[512];
theStream.Read(fileGroupDescriptor,0,512);
// used to build the filename from the FileGroupDescriptor block
StringBuilder fileName = new StringBuilder("");
// this trick gets the filename of the passed attached file
for(int i=76; fileGroupDescriptor[i]!=0; i++) {
    fileName.Append(Convert.ToChar(fileGroupDescriptor[i]));
}
theStream.Close();

// put the zip file into the temp directory
string theFile = Path.Combine("c:\\", 
Helper.RemoveUnwantedCharacters(fileName.ToString())).Trim();

MessageBox.Show("'" + theFile + "'");

try {
    if (File.Exists(theFile))
        File.Delete(theFile);
}catch{}

try {
  // get the actual raw file into memory
  MemoryStream ms = (MemoryStream) nseDataObject.GetData("FileContents", 
true);
  FileStream fs = new FileStream(theFile, FileMode.Create);
  ms.WriteTo(fs);
  fs.Close();
  ms.Close();
} catch (Exception e) {
  MessageBox.Show(e.ToString());
}

Best regards

4.Attach An outlook message to an outlook message

How do I attach an outlook email message as an attachment within
another outlook email message.

Right now I am using the following code.  But I was wondering if there
is a better way to do this without using a file that needs to be
deleted later.

private MailMessage addAttachment(MailMessage Mail, MailItem item)
{
                string path "Messages\\message" + message_id+ ".MSG";
                Mail.IsBodyHtml = true;
                item.SaveAs(path,
Microsoft.Office.Interop.Outlook.OlSaveAsType.olMSG);
                System.Net.Mail.Attachment attach = new
System.Net.Mail.Attachment(path);
                attach.Name = "OriginalMessage.MSG";
                Mail.Attachments.Add(attach);
                message_id++;
}

5.Drag & Drop of Outlook message + attachments to VB.Net form

Does anyone know how to drag&drop a message with attachments from Outlook
(2002 or 2003) in to a VB.Net windows form.
This is really stumping me.  I've spent a fair amount of time trying to find
a solution on the internet, with limited success.

I do have code to drag an attachment directly from Outlook to a form, but
not a whole message.
I want to have access to an object reprensenting the message so I can bust
out the message and attachments individually.

I have implemented a solution involving dragging the e-mail message from
Outlook to the desktop, then from the desktop to the windows form, but the
users don't want to do that and I don't think they should have to.

I've seen libraries and code that seem to make this easy using VB6, C++, or
COM, but almost nothing in .Net except simple examples of either files or
tree items, not Outlook e-mails directly onto VB.Net Winforms.

Any help appreciated.
Dave Anderson.
