problem, and neither does the sample plugin, but all of Niels
plugins do.  I can reproduce the problem with a single call to
the Plugin_Info function.  Everything seems fine when the
function returns but eventually the program hits the corrupted
memory on the stack and dies.

I really like the plugins, so I'd like to resolve this problem
if possible.  Since Orion's source for the bezier plugin is
available, I took a peek at it and the Plugin_Info function does
pretty much what I'd expect.  Do the Wheel or track generators
plugins do something else in that function?  What versions of
Delphi are you all using?  Maybe there's some note on the internet
that'll give me a clue...

Thanks,

Don

I have no idea what the problem could be unless Niel used an older version of
the plugin code.  This shouldn't be an issue with Delphi.

P.S. All the current developers at the LDDP project are using Delphi 6 or
higher.  As far as what Niel is using, I don't know.

I am using Delphi 3, which is (besides Delphi 1) the only version I've got. I haven't experienced writing DLLs before the LDDP plugins. The only info I had was the sample included with LDDP. Niels (21 years ago, 8-Jul-03, to lugnet.cad.dev)
