Hi,

when i try to compile the POP3 example (newest version, downloaded and installed yesterday evening :) for BCB (5.0 Upd. 1) i keep getting a linker error 'Unresolved external symbol CPowerPop3::CPowerPop3(void *).

This is the only error i get and the other examples (e.g. SMTP) compile and work fine.

What can I do? Is there any linker lib missing (I've found one: pt32bcb3.lib)?

Thanks in advance.
Bye, Discri.

The library you are referring to was built with BCB3, not BCB5. The toolkit is only supported for BCB3. If you need to use the library in BCB5, we'd have to recompile it using BCB5.

That may be something that we could do as a consulting job, so contact sales@dart.com if that sounds like an option to you.

Thanks for the fast reply.

I've just tried the other examples, too, and they fail (except the one I tried earlier: SMTP :) the same way (missing symbol for the class constructor).

Recompiling the linker lib just for me sounds like way too much work and too much money to me. I think I'll have to look for another solution for my project.

Thanks alot.

Have you tried the Mail Tool ( available on our downloads page ) There are BCB4/5 samples included.

I couldn't find any examples for BCB 5. For PowerBuilder and for Delphi but not for BCB5. Should it happen that they are compatible? (if I ever find the components I need for it :)

My apologies. I thought that I had written BCB samples for the Mail Tool. To answer your question, I don't see any reason why the product should not work with BCB5, but since there are no samples I can't say that there are not and BCB "quirks" that would cause problems.

You may be able to look at the Delphi samples to and figure out what to do.

If you can't I could probably get management to allow me to port the Delphi sample over if you purchased the tool plus support.

Please contact your sales rep , David Harry at sales@dart.com for more info. You should include a link to this topic in your correspondence.

I'll have a look at it but I must confess that I'am quite unexperienced in both Delphi and BCB (I use VC++ usually and I really don't like the Borland stuff, but now i'm forced to use it :( ) so it can take a while to figure out whether it works or not.

I'll give it a try tomorrow. (It's 6 p.m. here :)

Hmm... couldn't get anything to work with BCB5. I've tried to import the stuff (forms and sources) from Delphi5-examples (POP3 client, to be specific) but couldn't get anything to compile.

Anyways, PowerTCP is not the thing I need because I need classes which can be used in a thread. That means that i don't have a form to drop components or such.

Thanks for your help and Bye, Discri.
