Hi, I'm a programmer who has been using RealBasic / Xojo for many years
Over the years I have seen that many commands have been deprecated but with an improvement sense. The command has been replaced with a different but more functional one.
In the latest version, an abominable thing was done, many senseless commands were changed:
VAR instead of Dim
Rowcount instead of listcount
deleteallrows instead of Removeallrows
and many others including the getfolderitem
commands only changed in the name that in fact do not change anything in functionality, but only give headaches to programmers who have to carry the sources from version to version.
I hope you want to remedy this problem by keeping the compatibility in the 2 versions of the controls and that none of this will happen in future versions.
