whatever I try casting or comparing I'm stuck on errors
pointing out I cannot cast/convert `VariantN!32LU` to string.
I assumed an element range[] should be of type 'string', but
it seems to be of type `VariantN!32LU` whatever that is.
I really need help. I'm stuck.
You need to use .get!T on the variant, instead of casting.
Thank you it works like a charm.
I also found out that .toString works.
I should have been able to find toString immediately, but .get!T
I probably never have found myself. Can you tell which one is
best?
And the type `VariantN!32LU` why? It looks very odd to me.
I have tried to learn D a couple of times before, but always
given up on odd things like `VariantN!32LU`. This time I try a
bit harder. I do not learn well by books, courses or videos. I
learn by solving a small problem I have and then expand. My
intention is to build a compiler or an OS just for fun, or a
world class SAP connector. Right now I am too busy with life and
$work, the latter will end this year giving me more time for
programming. I hope D will work for me. Again thanks for good and
fast help.
