property node - help needed

[gigi85]

hello 🙂

here again 🙂 instead reading in chunks i have to read only a part of file..

i have some questions...i think about property nodes...

i would do this:

check if a file is bigger than a particular size

if is bigger than this size i would that appears a window in which a user can select which part of file would read (#part=filesize/#mysize + 1 in some cases)

if file size is < than my size, no windows selection and my program continue

my questions are:

-in which way can i make a window appear

-in which way can i make a selection and pass the index selected

i have done as in attachment but it doesn't work, in false case i put value = 0

This is how you can make a new window appear.

There is also the possibility to do it with a tab control making it (un)visible
