"List index out of bounds(0)" message

[Paco Ruiz]

Hi
I use Delphi7 prof (W98)
I have installed a component for testing it
Sometimes, i get the "List index out of bounds(0)" message when i try to
close my proyect or close delphi. And i MUST close Delphi with Ctr+Alt+Del.

I thougth the problem was with this new component, but in older proyects
(without this component) i get the same error.

Can anybody help me?

Seems like your third-party component is buggy. If the error even pops
up in your older projects that doesn't use these components it's very
likely that one of the finalization or initialization parts of the
package has a bug. These parts - as far as I know - are executed when
the Delphi IDE is starting (and loading the package) or when you quit
Delphi (and the package is unloaded). in other words: simply the fact
that you have *installed* a package can lead to errors because some code
of the package might be executed - it's not neccessry to actually *use*
one of the package's components.
If you've got the source of the package, look at the finalization or
initialization parts.

Oh, well, I forgot:
uninstall the package. If your old projects are running fine after that
then you can be sure it's the package that causes the error.

I have unistall the package and delete the asociated bpl files.
I still get the error when i try "Close All" and one TForm (always the
same) is open on IDE
(of course i have deleted the "buggy" component from this form and its
references on "Uses")
However, the proyect compiles and run fine.

Mmh, do you maybe have other third-party packages installed? If so, go
through them package by package: de-install one package, try if your
error still occurs, if so - next package.
If you don't have other packages installed I have no other clue what the
problem is. Try to find out *all* changes you did to Delphi after it was
freshly installed (or right before the error first showed up) - one of
these changes must be the reason. Did you maybe install third-party
experts? Did you recompile a unit of the VCL? (Something like
customizing your toolbar shouldn't be a reason for your problem, of course).
