    Running VB4 in WIN 95 and other questions

    Can the 16-bit version of VB4 be used within WIN 95-i.e. is this an
    installation option?

    Generally,can one assume that a WIN 3.1 based application can be run within
    WIN 95 (i.e. no compatibility problems?)

    Can WIN 95 files be successfully accessed/processed from within WIN 3.1?

    Given that there are "3 dates" for a WIN 95 file but one date for a WIN
    3.1/MS-DOS type file-if, say a WIN 95 file were edited and saved in WIN 3.1,
    if it was then used in WIN 95 would the last modified date or the creation
    date appear updated? (Unfortunately,I don't have WIN 3.1 to experiment with)

    Many thanks for any help-much appreciated.

    Mike Turner.

    Mike: Generally, yes, Win95 can run 16-bit Windows apps. Since VB4/16 is
    such an app, it works fine under Win95.

    Sure, why couldn't they be?

    The dates associated with a file in 32-bit versions of Windows are not store
    in the file itself, but in the directory listing for that file. Win 3.x has
    no access to the directory listing on the 32-bit OS, so it would only be
    able to update the DOS date. I'm not sure, however, which of the three
    32-bit dates that corresponds to.

    Thanks Phil,re following:

    >Sure, why couldn't they be?


    I was wondering about long file names.A relative wants,for some reason,to
    run both WIN3.1 and WIN 95 OS's on same PC.Would WIN 3.1 OS cope with long
    file names-displaying and accessing.(I know long filenames would be
    displayed by WIN 3.1 apps running in WIN 95 as mangled,but what about WIN
    3.1 apps running in WIN 3.1 and where there are long file names on disk).

    Mike: Win 9x's long file names are backward-compatible with DOS/16-bit
    Windows. The file names simply appear as DOS-style 8.3 names under the older
    operating systems.
