Converting message from EML to MSG format

[Jonny Au]

Hi everyone,

I have a problem about email message format converting.
I want to write a program in VB.NET to convert the EML format email message
to MSG format, does anyone knows how to do it?
If you know it you can send me a message to ckjonny5@hotmai l.com

Thanks at all.
Jonny

Wow! With all of those newsgroups you posted to and not one of them was
the correct one.

Almost everybody in this newsgroup (comp.lang.visu al.basic) is using VB6
or lower. While you may get a stray answer to VB.NET (including VB2003
and VB2005 which has dropped .NET from its name) questions here, you
should ask them in newsgroups devoted exclusively to .NET programming.
Look for newsgroups with either the word "dotnet" or "vsnet" in their
name.

For the microsoft news server, try these newsgroups for Visual Basic
..NET related questions...

microsoft.publi c.dotnet.langua ges.vb
microsoft.publi c.dotnet.langua ges.vb.upgrade
microsoft.publi c.dotnet.langua ges.vb.controls
microsoft.publi c.dotnet.langua ges.vb.data

And these for more general .NET questions

microsoft.publi c.dotnet.genera l
microsoft.publi c.vsnet.general

Note: There are many other .NET newgroups (use the first three "fields"
from the last two as templates when searching for them), but the above
ones should get you started.

Please don't crosspost. You will get a good answer posting to the narrowest
one or two groups possible.

The programming and extreme-programming groups are about general philosphy
and methodology, respectively.

What did Google tell you about these two formats? Did you find a document
declaring their standard anywhere?

Post here read here. This is not a private tech support service, and if we
reply on USENET others will review our answer. And we will leave an archive
for Google.

I've trimmed the list of newsgroups to the most relevant ones.

.eml format looks like it's just MIME, so any MIME library should do
the trick; maybe .net has one, I'm not sure, but I've heard people
recommend mime++ for that sort of stuff in the past.

As for saving in .MSG format, see

http://support.microsoft.com/?kbid=171907

That's extended MAPI code, which doesn't really play nicely with .NET:

http://support.microsoft.com/default.aspx?scid=kb;en-us;872895

so you can either try wrestling with interop to pull it in, or put that
code into a DLL and call the DLL from your .NET code or somesuch. Yet
another option (though probably a nastier one) would be to parse the EML
message into chunks, use OOM code to populate a message that way, and
then tell the OOM to save the message in .MSG format. I'm not 100% sure
that's all possible, but it may be easier if you can't use C++.
