Control

Is there is a way (control or whatever) to know every programs,company name and version on the PC?

VB Code:

Private Type VS_FIXEDFILEINFO
   dwSignature As Long
   dwStrucVersionl As Integer     '  e.g. = &h0000 = 0
   dwStrucVersionh As Integer     '  e.g. = &h0042 = .42
   dwFileVersionMSl As Integer    '  e.g. = &h0003 = 3
   dwFileVersionMSh As Integer    '  e.g. = &h0075 = .75
   dwFileVersionLSl As Integer    '  e.g. = &h0000 = 0
   dwFileVersionLSh As Integer    '  e.g. = &h0031 = .31
   dwProductVersionMSl As Integer '  e.g. = &h0003 = 3
   dwProductVersionMSh As Integer '  e.g. = &h0010 = .1
   dwProductVersionLSl As Integer '  e.g. = &h0000 = 0
   dwProductVersionLSh As Integer '  e.g. = &h0031 = .31
   dwFileFlagsMask As Long        '  = &h3F 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
