Hello (it's been a while), is there a particular value using lpstrFilter value to still open all files, yet not show (or hide) read_only files from the explorer window? About the only workaround I found so far was to use ofn_noreadonlyreturn in the flag. That causes the file not to load, though I'd much prefer simply to have the file not pop up inside the explorer window at all.
... any suggestions? Danke.
