Is there a VCL component, or something else in Borland's component library,
that simplifies dealing with data in HKEY_CLASSES_ROOT -- specifically:
registering file types and also querying info about existing file type
associations?
Thanks,

extensions.
The Win32 API has an IQueryAssociations interface for querying (but not
assigning) the more common settings, but does not provide access to many of
the more advanced settings.

Is it possible to use this component in BDS2006?
If so, how would I go about it?
Thanks,
David

2007. Two small things:
1) When you use the Add() that takes a TExtInfo*, is this right:
TExtInfo *xi = new TExtInfo(".test1", Application->ExeName, "Test 1",
0);
RX->Add(xi);
RX->Register();
That seems to work OK (RX is the TRegExtension) -- except if I delete xi,
then an access violation occurs in TExtCommands::Clear when my program
exits. Looking at TExtCommand::Clear(), it appears that I should not delete
xi since Clear() deletes all the TExtInfo's I've Add()ed. Is this a general
behavior of "collections" -- if you add an item it takes "ownership" of it,
then if you Clear() the collection it deletes all your objects? Mostly I'm
just wondering; for when I write components in the future, to stick to
normal expected behaviors.
2) The docs for "TExtInfo::Extension" property say it adds a leading dot if
you don't put one in. On the other hand, specifying an extension to
TRegExtension::Add or the TExtInfo constructor does not seem to add a
leading dot if one is missing. Just to let you know.

it. It works for 2007, too.

I can build it but I'm not sure how to install it. Could you advise, please.

overloaded versions of Add() instead, ie:
RX->Add(".test1", Application->ExeName, "Test 1", 0);
for you.
actually do that. In the new version I am working on, it does do it,
though. So, in the meantime, just make sure to always include a leading dot
in your extension string values.
Extension property via the same setter as if you had assigned it manually.

IDE, build it, and then use the Project Manager's "Install" option.

I'd forgotten where to find the 'Install'. Found it now. Just
one of the trials of old age.
Cheers,

You should be able to load the project, then right-click on the BPL file in
the project manager and "install".
Alternatively, if you normally keep your package BPL, BPI, LIB, and header
files in some other location, just build it, don't install it, then copy the
BPL, BPI, and LIB files from the project directory to wherever you want
them, and copy RegExtensions.h to an appropriate location, too. Then you can
install the package by choosing "Install Packages" from the "Component" menu
and browsing to the files.
