Members

  • dwStrucVersion
    Binary version number of this structure. The high-order word of this member contains the major version number, and the low-order word contains the minor version number.
  • dwFileVersionMS
    Most significant 32 bits of the file's binary version number. This member is used with dwFileVersionLS to form a 64-bit value used for numeric comparisons.
  • dwFileVersionLS
    Least significant 32 bits of the file's binary version number. This member is used with dwFileVersionMS to form a 64-bit value used for numeric comparisons.
  • dwProductVersionMS
    Most significant 32 bits of the binary version number of the product with which this file was distributed. This member is used with dwProductVersionLS to form a 64-bit value used for numeric comparisons.
  • dwProductVersionLS
    Least significant 32 bits of the binary version number of the product with which this file was distributed. This member is used with dwProductVersionMS to form a 64-bit value used for numeric comparisons.
  • dwFileFlagsMask
    Bitmask that specifies the valid bits in dwFileFlags. A bit is valid only if it was defined when the file was created.

  • dwFileFlags
    Bitmask that specifies the Boolean attributes of the file. The following table shows the possible flags for this member.

    Flag Description

    VS_FF_DEBUG

    The file contains debugging information or is compiled with debugging features enabled.

    VS_FF_INFOINFERRED

    The file's version structure was created dynamically; therefore, some of the members in this structure may be empty or incorrect. This flag should never be set in a file's VS_VERSIONINFO data.

    VS_FF_PATCHED

    The file has been modified and is not identical to the original shipping file of the same version number.

    VS_FF_PRERELEASE

    The file is a development version, not a commercially released product.

    VS_FF_PRIVATEBUILD

    The file was not built using standard release procedures. If this flag is set, the StringFileInfo structure should contain a PrivateBuild entry.

    VS_FF_SPECIALBUILD

    The file was built by the original company using standard release procedures but is a variation of the normal file of the same version number. If this flag is set, the StringFileInfo structure should contain a SpecialBuild entry.

  • dwFileOS
    OS for which this file was designed. The following table shows the possible flags for this member.

    Flag Description

    VOS_DOS

    The file was designed for MS-DOS.

    VOS_NT

    The file was designed for Windows NT and Windows 2000.

    VOS_OS216

    The file was designed for 16-bit OS/2.

    VOS_OS232

    VOS_UNKNOWN

    The OS for which the file was designed is unknown to the system.

    VOS__WINDOWS16

    The file was designed for 16-bit Windows.

    VOS__WINDOWS32

    An application can combine these values to indicate that the file was designed for one OS running on another. The following table shows the dwFileOS flags, but is not a complete list.

    Flag Description

    VOS_DOS_WINDOWS16

    The file was designed for 16-bit Windows running on MS-DOS.

    VOS_DOS_WINDOWS32

    The file was designed for 32-bit Windows running on MS-DOS.

    VOS_NT_WINDOWS32

    The file was designed for Windows NT and Windows 2000.

    VOS_OS216_PM16

    The file was designed for 16-bit Presentation Manager running on 16-bit OS/2.

    VOS_OS232_PM32
