For code-only DLLs, check "Register for COM interop" in the project
properties and reference the generated TLB file from within the VB6 project.
..NET user controls cannot be used on VB6 forms.

Sorry about that, I didn't put 2 and 2 together on that.

Hers my situation...
We have an application written in C++(I was using vb6 as a test, still the
best test language in the Universe)
that allows for users to create plugins. The plug-in architect has both code
only and UI interfaces. Both are
needed to create a sucessfull plugin. This is done in VB6 by creating a user
control. The ctl is used to interface with the plug-in UI and then
in VB6 another class is added which communicates to the Plug-in code only
interface. The 2 work in concert. Works beautifully
How can I do this with .Net?

Is this at all possible. We have many useres world wide who would like to
create plug-in's using .Net.
Can something be done on the C++ app to handles this?

Thanks for your help and expertise.

I have done stuff like this before. You can only show forms created in
..Net, you cannot place a "user control" on the VB6 application. For
example, we have a scanner interface that we developed in VB.Net and
created a COM interop assembly. In this assembly we have a form that
will popup and the user can select the source, scan an image, save it,
view it, etc. This is all controlled through the assembly. You can then
create methods and properties to communicate the data back to the VB6
application. Just remember, it will show up as a separate form and not
embedded on the VB6 forms.

Since this is a plug-n it needs to be hosted within the C++ app and cannot
be a seperate or pop up form.
it needs to live in a special place in the C++ app.

Lou, if this has to be a .Net UserControl and has to be displayed
embedded on a VB6 form, you cannot do this, no matter how hard you try.
It is just not supported at all. There isn't even a work around. You can
call code from a COM aware .Net assembly, but you cannot host .Net
UserControls on the VB6 forms. If you absolutely have to do this, then
convert your VB6 app to .Net.

There are workarounds available
(<URL:http://www.codeproject.com/cs/miscctrl/exposingdotnetcontrols.asp>)
but this doesn't make it a supported scenario.
