Your findings confirm what I already found and wrote in a previous
posting that the ImageList is returning a completely different size in
BDS4 than it does in BCB5
Don, I have 'TurboC++ 2006 Explorer' ( is hte C+ personality of BDS4
with restrictions) and found a way to use TZipBuilder without installing
it in the IDE.
I can offer two solutions.
1- I changed CDemo1 so that it does not use TImageList to store the
icons but invisible TImage components. After testing it with TC2006 I
will put the updated files on my website.
2- I will try to find a way code that allows replacing the icons with a
larger or smaller one. Don't know if that is possible and will require
some more research and testing.
