Dave,

I would look at the section of the .NET documentation titled "Exposing
..NET Framework Components to COM", located at:

Well, this is pretty easy to do,
Just expose your C# assembly as COM,
and it will work just fine in your VB6 code.

[singing]
But there is a part of me
that would like to tell
and thereby lie
that it is impossible..
Just to have you re-write
your entire application
- Just to rid the world of VB6 =)

But, I am happy too see you are moving in the right direction.

I agree, i would never write vbcode and i still hate it...
this is legacy code
For the time being i can't rewrite yet
But im trying to slowly a Part at a time

Well, I'll pray for you.
Anyone doing VB6 without wanting to,
deserves to have a candle lit for him/her.

But you will find that it is easy to get an
assembly to work in the COM-world.
Just a checkbox if I remember correctly.

In the meantime, you can always laugh with Verity Stobs:

Michael,

Any reason, just try the VBNet version from what is in C# the switch, maybe
that is the first start in loving VBNet.

I usually settle for coffee.

But when I maintain VB6 code,
I am always thinking that I need LSD
to even begin to understand what the
original coder was trying to do.
And what all the patches ontop of that
was trying to solve in panic.

I wonder if there is a support group for this?

- eh, eh, I've been like a VB6 maintainer for..
... a long time now...
... sometimes I get VB6, but sometimes they only give me VBA
... for office-applications..
... also, I had to do vbscript in asp, just to get a new hit
... been doing that...
... for like 6 years now. I'm shaking and can't sleep
... because of all the nightmares.
... my name is Michael

- HELLO MICHAEL, we are here for you...

Luckely for me, C# came to the rescue.
Also, I have still a pretty complex
Delphi7 application that I work on, on my free time.

If not, I'd been in that support group,
becoming Tyler Durden making viruses targeting COM.

Cato said in the Roman Senate
that Carthago should be destroyed.
That is a missspelling by the dude taking notes,
or maybe the Cato was a wee drunk and slurled it out
but, he ment that COM should be be destroyed.

See, that is what I call an insight.

But Bill don't take orders from Cato, now does he. =)
