Delphi 3: How to add components as .dcu files to Packages ???
Erwin de Groot
Does anyone know how I can add 3rd-party d1 and d2 components, only
known as .dcu files, to the new package-structure in delphi 3?
I can add them... But for compiling the package you have to have the
source (as it seems)
Please,... if you do know the answer... respond!
Greatings from Erwin de Groot.

D1 dcu files cannot be added because they are 16-bit compiled code. D2 dcu
files seem to have a slightly different format than D3 dcu files so they
don't compile either. You need original D3 dcu files or the source.

I don't know about D3 but in D2 you have to make sure you select the
*.DCU file while adding a component to the component palette. In D2 you
have a choice of selecting either *.PAS or *.DCU.
If you add the (compiled) *.DCU file the DCU will only be linked and not
compiled if the *.PAS is not found.

I have the same problem and I can't use my Delphi 2 components
with Delphi 3. That's why I am still programing with Delphi 2.
Delphi 3 allways asks for the .PAS.
May be, you must install packages with Delphi 3 (.DPL) ?

No offense, but I think you are wrong (about Delphi 3.0 only
allowing .PAS files to be installed).
In Delphi 3.0, select the "Component" menu, "Install Component",
hit the "Browse" button, and change the "File of Type" to .DCU.
Of course this will only install Delphi 3 DCU's and not Delphi
2 DCU's.

With some component in the Delphi 3 page of DSP I have the same
problem. May be it is not Delphi 3 component in fact.
Borland could allow Delphi 3 to use Delphi 2 components !!!

I noticed this too. The Globe component is listed for D3 on the DSP; but it
is pretty obviously a D2 DCU.

Hi all,
This comment has been here before,
It isn't strange Delphi 2 components (in DCU form) can't be used as Delphi
3 component's becouse they are used completely different in the VCL.
You can't use Delphi 1 DCU in Delphi 2.
This is a normal procedure if you want the VCL to be improved majorly.
Happy coding.

I've spent about three hours reading all the help and playing with
everything, and I've come to the same conclusion! Surely they wouldn't
do this! It would put an end to all the freeware and shareware component
development!
I hope we're wrong. Does anyone else know the answer?

Nope. He is mostly right. Packages are a superset of DCU's - DCU's
still exist. But the internal structure HAS changed from D2 to D3; you
DO need the source to move from version to version.
And any software who's author will not provide either source or
recompiled DCU's on request is not worth using.

This must be about the most frequently asked question/complaint there is.
It's not possible. Borland made a lot of changes/updations to the VCL between
2 and 3. DCU components compiled for the VCL verison 2 simply will not work
will VCL version 3. In Borland Pascal's long history, there has never been
a single version that had unit compatibility with a previous version. To do
so would force them to not update the underlying libraries.
Personally, to your other complaint, I think that any author that wouldn't
either release the source code, or recompile a new version for Delphi 3
isn't worthy of using in any case.

Yeah, They could do that if Delphi 3 had a VCL that was EXACTLY the same
as the Delphi 2 VCL. But then why would anyone upgrade????

what really torques me is that there's no warning or error about incompatible
dcu format, it just ignores the dcu completely.
i was not pleased at all at this lack of compatibility. if anything like this
happens to me again i'm through with borland

Despite the fact that Borland have NEVER had a compatible DCU format from one
version to the next, you now get people coming out of the woodwork whining
about it now?

What people like this fail to recognise is that Borland changed their VCL
from 2 to 3. It was necessary to support all those cool new COM features and
stuff. And since DCUs are a precompiled file, files compiled to rely on the
old VCL are of course not going to work with the new VCL, even if the DCU
file format WAS the same.
Geeze, if it pisses you off so much, stay with Delphi 2. Certainly no-ones
forcing to you use Delphi 3.

That's the rub - If you try to install a Delphi 3.0 compiled DCU, no
problem. BUT, if you try it with a Delphi 2.0-compiled DCU, and try
to compile the package, D3 will realize that the DCU is in the "wrong"
format and search for the PAS file to recompile it into the new D3
format. So the bottom line is that any DCU you try to install into D3
NEEDS to be compiled in the D3 format.
This now tops my list as the all-time stupidest thing Borland's ever
done (or not done).
