File filter, how to use it?

[23fx23]

I got two functions that use sdk file dialog stuff to read/write from specified file.

but i fail to understand how the 'filter' works.
ie Its supposed on open to only display .bin files, but i can see for ex a text file here.

i tried to set the ansicharpt to "(*.bin)" or "*.bin" , or ".bin", or "bin", but no luck..
any clues?

oops sorry found the answer on microsoft site, need to use a bar ' | '
ie in my case tried "Curve files | *.bin"; and that works, only see bin files now

in case some would have similar wonders:
