Deploying as a DLL

Hi,

I've reading some posts on this NG but I'm not sure if I can deploy a
DLL with DST 5 or not.

As a DLL could be interesting to develop a component as 3rd party
developer this could be useful.

If I can make a dll from dolphin I would like to know:

How do I define the API of this DLL?

I know it seems to have no sense, but can I pass Objects as arguments?
perhaps serialized?

Could somebody give some guidelines to this lost soul?

thanks :)

You can, but AFAIK, only COM DLLs.

Assuming my response above is correct, then you would write IDL, use MIDL to
compile it to get a type library, then some wizard use and little category
dragging will fill in the details. See the Wiki for Blair's instructions.

You can pass interface pointers to COM objects, and you can pass around
blobs of memory containing serialized objects, but in that case, the caller
almost certainly has to be Dolphin-based too, unless you agree on some
common format besides STB.

Have a good one,

Bill

Ouch, OK, that's a pity, I'll see what to do... :-/

Yes I was thinking on a dolphin-based user.

Bill is correct. You cannot create "C-style" function based DLLs with
Dolphin. You can create in-process COM components in DLLs however.

If all your clients are written in Dolphin, and you want to pass Dolphin
objects backwards and forwards, then it might be worth checking out the binary
packaging mechanism (as used in theWeb Deployment Kit).

Here's an example:

Create a new package, say called 'Temp'

Create a new class in that package, say called 'AAATemp'.

Give it a method:
==============
AAATemp>>tryMe
Notification signal: 'It worked'.
==============

In the package browser, select the package and "Deploy Binary Package". You'll
be prompted for a "certificate", just click OK (which will deploy with no
certificate). You should now have a 'AAATemp.pak' file.

Start a clean image, from it evaluate:
cl := ClassLocator codeBase: '' packageName: 'Temp' key: 'AAATemp'.
class := cl locateClass.

You'll be prompted for whether you want to "trust" the loaded code (with no
certificate). Answer yes.

Now you can use your dynamically loaded class:

class new tryMe.

should print 'It worked!' to the Transcript.

Binary deployment may or may not suit your requirements, but it is an
alternative to DLLs.

Cannot Deploy usual DLLs tha's OK so...

In reply to this post by Bill Schwab

OK,

I'll change my question now.

How do you make that a dolphin application interact with anhoter dolphin
application in the same host?

Do you use the socket approach as a particular case (local-local)
between aplications or do you prefer inter process comunication?

In the last case how this could be archieved?

thanks

If you are looking at Smalltalk<->Smalltalk communication, then the Dolphin
port of rST at
http://www.smalltalking.net/goodies/Dolphin/
may be worth checking. (I haven't looked at it myself).

For a very simple approach you might take a look at the (Agent-) Chat
example application. It uses sockets to pass an STB encoded String between
the two running apps.
