ABC Frequently Asked
This can happen if all of the ABC design packages
have been disabled (unchecked) or removed in the Component | Install
Packages dialog and you try to activate or add one of the packages.
SOLUTION: Add the Shared Property Editors package first (dclABCxx).
The "Lite" versions of ABC do not contain
any dcu files. So you must compile all projects with the
Project|Options|Packages - Build with Runtime Packages checkbox
checked. The package names list should also include the
appropriate runtime package - ABCC for Delphi6 and up, ABCC50, ABCC40, etc. The Library Path
must also point to the abc directory containing the relevant .dcp or
This problem has been reported to us on a few
occasions, where it started to occur just after installing
ABC. Borland has identified this as a known problem with the
Microsoft ImageList common control and some video drivers:
"Some older video drivers (S3 Virge GX, Diamond
Viper, Riva TNT, Matrox Millenium, and others) have trouble handling
the quantity of images that the Delphi IDE's component palette
places in its internal ImageList control. This can cause the
component icons to appear shifted or corrupted in the IDE component
palette. The solution is to contact your video card vendor for an
updated video driver. At the time of this writing, all the video
drivers known to exhibit problems with the Microsoft ImageList
control have been updated with fixes by the video card
vendors. You can also work around this ImageList problem
by reducing or disabling video hardware acceleration in your Windows
configuration settings. For instructions, consult your operating
system and video hardware documentation." (from Delphi 5
A frequent cause of errors is trying to load
incompatible package versions. This might be reported as a
missing function entry point not found in a required package, or as
"a device attached to the system is not
This could have two common causes:
- Installing a new ABC version into a different directory while
an older ABC version is still installed in Delphi.
- Version updates or patches from Borland that are not installed
on your machine.
In the first case, just answer No to all the version errors when
Delphi asks if you want to load the package next time. After
all the errors, the new installed ABC packages should work properly.
In the second case, you may need to check versions
and install additional Update Packs. We always endeavour to
ship our software built for the latest shipping release of each
version of Delphi or C++ Builder, with all Update Packs

The ABC ADO adapter package is only automatically
installed to the component palette with the Enterprise edition of
Delphi. If you have purchased the ADO add-on for Delphi 5 Pro,
you can add the ABC ADO Adapter class to the IDE. Choose Component |
Install Packages | Add and then choose the
These problems may occur at runtime using
TabcFormPanel, TabcAnimationFrame or one of the abcNotebook
components with embedded forms.
The most frequent cause is a coding issue,
referencing the Delphi unit variable (var Form1: TForm1) in your
code when the ABC container component has created its own different
instance of the form.
If embedded forms are not autocreated by Delphi in
the project options, or by your code using Application.CreateForm
then it's most likely this variable is unassigned.
If the form you want to embed has been autocreated
by Delphi and you want to assign it to the container, use the public
Form property of TabcFormPanel or TabcPage (in the AnimationFrame).
