Access violation in VCL50.BPL

components (Dream Outbar). Now when I open a particular form that uses these
components, I get error messages like:
Error reading PassportForm.Font.Name: Access violation at address 40070AF3
in module 'VCL50.BPL'. Read of address FFFFFFFF. Ignore the error and
continue? NOTE: Ignoring the error may cause componenets to be deleted or
property values to be lost.
Error reading DCOutBarGroup9.Font.Color: Access violation at address
40070AF3 in module 'VCL50.BPL'. Read of address FFFFFFFF. Ignore the error
and continue? NOTE: Ignoring the error may cause componenets to be deleted
or property values to be lost.
(PassportForm is the form containing the Outbar component; DCOutBarGroup9 is
one of the Outbar components.) I can't run the app -- it bombs out with
similar access violations, at a different address but concerning the same
component properties.
Suggestions? I've posted this question to Dream tech support as well, but
I'm a little desperate for a fix.

AVs in the Delphi IDE can be (and frequently are) caused by buggy
third party components. Sounds like you are already pursuing the
correct path, with the vendor.

Follow-up to my own desperate plea: this would appear to be a problem with
the new version of Dream Outbar. When I removed it and re-installed the old
version, I found I can once again open and run the project with no problems.
So for the time being, until I hear the problem is resolved, I just won't
install the upgrade.
Anyone else have problems with the new Dream Outbar? The interesting thing
is that it happens to me in one (fairly complex) form that uses these
components, but not in another (simpler, ancestor) form.

Things to try:
A) Ensure old source is not in Delphi Path.
B) Old Dream bar is uninstalled (Remove package from Delphi,
and delete the BPL)
C) Add new source to Delphi Path
D) Do a Build All in your project <------- Very important
I haven't got time to install the update and test it with
the apps I have used but give it a try. My guess is it's
getting confused between the old and the new versions
somewhere.
Or there's a bug :)

using some of the other Dream components and Dev Express. I think it will
be a long hunt to find the culprit for me. Glad to know that it is probably
not Delphi though, although I think I've seen this and other access
violations in certain instances just with Delphi; usually involving visual
inheritance with datamodules.

a patch to dcoutbar.pas waiting for me in my inbox. I installed the patch
and it seems to be working just fine. If you can nail it down to a
particular component or set of components, I recommend getting in touch with
the developer.
