Reading the version of an EXE

[Kzin]

How do I read the version number of an EXE (not the one that I'm running but a separate one on the HDD)?

Thank you.

I think I need to type def VS_FIXEDFILEINFO etc. to make this run. Can you help with that?

[SLH]

Use the APIViewer
"C:\Program Files\Microsoft Visual Studio\Common\Tools\Winapi\Apiload.exe"

Public Type VS_FIXEDFILEINFO
        dwSignature As Long
        dwStrucVersion As Long         '  e.g. 0x00000042 = "0.42"
        dwFileVersionMS As Long        '  e.g. 0x00030075 = "3.75"
        dwFileVersionLS As Long        '  e.g. 0x00000031 = "0.31"
        dwProductVersionMS As Long     '  e.g. 0x00030010 = "3.10"
        dwProductVersionLS As Long     '  e.g. 0x00000031 = "0.31"
        dwFileFlagsMask As Long        '  = 0x3F for version "0.42"
        dwFileFlags As Long            '  e.g. VFF_DEBUG Or VFF_PRERELEASE
        dwFileOS As Long               '  e.g. VOS_DOS_WINDOWS16
        dwFileType As Long             '  e.g. VFT_DRIVER
        dwFileSubtype As Long          '  e.g. VFT2_DRV_KEYBOARD
        dwFileDateMS As Long           '  e.g. 0
        dwFileDateLS As Long           '  e.g. 0
End Type
