Hi!

We have been working with some TFrames descendant created by ourselves
but We are having some problems since they have to be updated for some
projects but We want to keep older versions for another projects until
We have time to test if the updates on the frames work well with that
project. Up to know We are including all source files in every project
and We decided that they should be in a library or package so We can
choose when to update files.

I don't know if creating a package is the best choice so if you have a
better idea please tell me, but anyways I've been trying to make the
package with no luck at all.
I took the source files, added the PACKAGE macro, and created de
ValidCtrCheck and Register methods, but I'm having two problems:
1- The IDE modifies the DFM as if it was a TForm
2- No component is added at all after compile+install.

I read about the problem (1) in some website and I'm compiling from
command line to avoid the IDE modification, but no luck with (2).

I also tried a silly example with no luck either: created a TFrame with
a CheckBox, created package, installed succesfully, but when I used it
on an application to test it I got an "class TCehckBox not found" error.

Please, any ideas/tutorials?

BTW: I'm using BCB5

Ok, I'll change the questin since I managed to solve the previous problems.

My TFrame is a kind of excel's pivot tables, and among other things it
generates reports through QuickReports. Now I managed to build the
package but I cannot install it because of this error

---------------------------
C++Builder 5
---------------------------
Cannot load package 'TablasPackage.' It contains unit 'Qrprnsu,';which
is also contained in package 'Qrpt50'
---------------------------
OK
---------------------------

I didn't add that unit by hand, nor is in the bpk or cpp source. I guess
it hast to do with QRPT50 lib I use from the frame... Is there any way
to solve this?

Ok, I know... I should try harder before asking... One step ahead! I
solved the previous error by including the required bpis on the required
section.

Now I have another problem but I guess this time is related to my source
code, but I don't know how to solve it.

I have a TFrame descendant. Let's call it TFrameDesc1. It's an abstract
class son I cannot generate a component from it, but I do have two
different descendants from that class that are not virtual, let's call
them TMyFrame1 and TMyFrame2.

These two frames are the ones I want to be generated as components in a
package.

I created the package, included required bpis and all the required cpp
files auxiliary to TFrameDesc1 and the two descendants, but when I add
the TMyFrame1 unit I get an "Ancestor Component not found" for a
component that was defined in TFrameDesc1 and inherited in TMyFrame1.

After several tests I managed to create the componente by generating a
makefile, copying the dfms from the originals, making and installing. It
works fine while I don't enter on the cpp files while debugging. (again
the inherited problems).

Am I doing something wrong? What am I missing?

If I understand what you are describing it looks like you need to have the
ancestor frame's unit open in the IDE before you attempt to open the
descendant frames' unit or any form in which you've dropped one of the
descendant frames. I deal with this all the time when I have datamodules
and frames in packages.
