Wrapping .net code for VB6 use

Greyhound

7/8/2011 1:51:00 PM

I have created an email library in .net and need to call this library
from a VB6 application. Can someone tell me if this can be done and,
if so, how to go about it.
Many Thanks

Look at COM interop and exposing COM interfaces.

Yes, it can be done, but it's really a question for a .NET group. Pointers
in canned reply below:

This is a VB "classic" newsgroup. Questions about VB.NET (including VB
2005/2008 and VB Express, which have dropped .NET from their names) are
off-topic here.

Please ask .NET questions in newsgroups with "dotnet" in their names. The
*.vb.* groups are for VB6 and earlier.

For questions specific to the VB.NET language, use this group:

microsoft.public.dotnet.languages.vb

Please note that things like controls and data access, which have their own
subgroups in the Classic VB hierarchy, are not language-specific in .NET, so
you should look for groups like these:

microsoft.public.dotnet.framework.windowsforms.controls
microsoft.public.dotnet.framework.adonet

(Note that "vb" is not present in the group name.)

Why not just write it in VB6 and save yourself
hundreds of MBs of .Bloat dependencies? There's
no sense hiring a Mac truck to deliver a pizza.

Here's one sample of SMTP:
www.jsware.net/jsware/vbcode.php5#mail

There are others. There's a DLL called VBSendMail.
And I think there's POP3 code around.
Isn't CDO/CDOSys also available on 2000+?

You haven't said whether your library will be on a local or remote machine.

Dee has already explained that you can create a COM wrapper for your DLL
and call it directly.

However, you may wish to run it on a web server - it depends why or what
you need to email, and whether it has to be addressed from the sender.

There are a couple of options in this case:
- create a web service and call it using, say, PocketSOAP
- create an HttpHandler and call it using MSXML (which is what I do).
