Hi Mark,
In IDL6.3, the "idl32.dll" was renamed to "idl.dll" so that both the 32-bit
and the 64-bit Windows would have the same DLL name (same thing for
"idl.lib"). This makes it simpler for someone to have a makefile that they
can use to compile their own DLL on both 32-bit and 64-bit Windows, and not
have to change the IDL library name. This change is documented in the IDL6.3
release notes.
In any case, the entry points have changed enough between IDL6.2 and IDL6.3
that a previously-compiled dll will not work, even if the library names
hadn't been changed. So really, someone needs to recompile the avi.dll and
link it against IDL6.3.

Hear hear!

Thanks Ronn
I tried out the new 6.3 version. It is not writing AVIs properly. As
you know, your test program aviKRtest.pro calls avi_openw with the
OPTION keyword set, so that it shows a "Video Compression" dialog for
setting the AVI format etc. If I accept the default (Full Frames
Uncompressed) then an AVI file is produced, but it is not readable,
either by the IDL code later in the routine or by an external
application. If I change the AVI format to Microsoft Video 1 (an oldie
but a goodie) then I get an error: "AVI_OPENW: Unable to avi stream
format".
BTW: at your leisure, perhaps you could clarify the relationship
between your DLM and Oleg's DLL and your plans for the DLM. Is there
any chance of merging some of Oleg's 2005 improvements into your
version? Also, do you intend to keep upgrading your DLM for new
versions of IDL. (I presume you do, as you have just done it for 6.3!).
And does/could your DLM work with 64-bit Windows? As I have said, I
find your DLM extremely useful and am keen to see it continue. I would
be willing to pay money to ensure this happens.
BTW 2: receiving new IDL versions Here in NZ *before* everyone else is
a new experience. IN the good old days we were weeks behind. They must
be feeding the carrier pigeons extra rations!
