Work with winmail.dat (TNEF Parser)

When an Outlook user composes and sends a message using either Rich Text Format or HTML Format, Outlook automagically generates a file, winmail.dat, and attaches it to the end of the email. The winmail.dat contains the rich text body and original attachments. EAGetMail provides the TNEF parser to decode the winmail.dat. With this feature, you application has the highly compatibility with the outlook email.

Example

[Visual Basic, C#] The following example demonstrates how to deal with the winmail.dat attachment. To get the full samples of EAGetMail, please refer to Samples section.

[Visual Basic]
Dim oMail As New Mail("TryIt")
oMail.Load("c:\test.eml", False)
Dim atts() As Attachment = oMail.Attachments
Dim tempFolder As String = "c:\temp"
Dim count As Integer = atts.Length
If (Not System.IO.Directory.Exists(tempFolder)) Then
    System.IO.Directory.CreateDirectory(tempFolder)
End If

For i As Integer = 0 To count - 1
    Dim att As Attachment = atts(i)
    'this attachment is in OUTLOOK RTF format, decode it here.
    If (String.Compare(att.Name, "winmail.dat") = 0) Then
        Dim tatts() As Attachment
        Try
            tatts = Mail.ParseTNEF(att.Content, True)
            Dim y As Integer = tatts.Length
            For x As Integer = 0 To y - 1
                Dim tatt As Attachment = tatts(x)
                Dim tattname As String = String.Format("{0}\{1}", tempFolder, tatt.Name)
                tatt.SaveAs(tattname, True) 
            Next
        Catch ep As Exception
            MessageBox.Show(ep.Message)
        End Try
    Else
        Dim attname As String = String.Format("{0}\{1}", tempFolder, att.Name)
        att.SaveAs(attname, True)
    End If
Next

[C#]
Mail oMail = new Mail("TryIt");
oMail.Load( "c:\\test.eml", false );

Attachment [] atts = oMail.Attachments;
int count = atts.Length;
string  tempFolder = "c:\\temp";
if( !System.IO.Directory.Exists( tempFolder ))
    System.IO.Directory.CreateDirectory( tempFolder );

for( int i = 0; i < count; i++ )
{
    Attachment att = atts[i];
    //this attachment is in OUTLOOK RTF format, decode it here.
    if( String.Compare( att.Name, "winmail.dat" ) == 0 )
    {
        Attachment[] tatts = null;
        try
        {
            tatts = Mail.ParseTNEF( att.Content, true );
        }
        catch(Exception ep )
        {
            MessageBox.Show( ep.Message );
            continue;
        }
        int y = tatts.Length;
        for( int x = 0; x < y; x++ )
        {
            Attachment tatt = tatts[x];
            string tattname = String.Format( "{0}\\{1}", tempFolder, tatt.Name );
            tatt.SaveAs( tattname , true );
        }
        continue;
    }
    string attname = String.Format( "{0}\\{1}", tempFolder, att.Name );
    att.SaveAs( attname , true );
