Members

dwSignature

Contains the value 0xFEEFO4BD. This is used with the szKey member of the VS_VERSION_INFO structure when searching a file for the VS_FIXEDFILEINFO structure.

dwStrucVersion

Specifies the 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

Specifies the 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

Specifies the 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

Specifies the 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

Specifies the 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

Contains a bitmask that specifies the valid bits in dwFileFlags. A bit is valid only if it was defined when the file was created.

dwFileFlags

Contains a bitmask that specifies the Boolean attributes of the file. This member can include one or more of the following values:

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_VERSION_INFO 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

Specifies the operating system for which this file was designed. This member can be one of the following values:

Flag	Description
VOS_DOS	The file was designed for MS-DOS.
VOS_NT	The file was designed for Windows NT.
VOS__WINDOWS16	The file was designed for 16-bit Windows.
VOS__WINDOWS32	The file was designed for the Win32 API.
VOS_OS216	The file was designed for 16-bit OS/2.
VOS_OS232	The file was designed for 32-bit OS/2.
VOS__PM16	The file was designed for 16-bit Presentation Manager.
VOS__PM32	The file was designed for 32-bit Presentation Manager.
VOS_UNKNOWN	The operating system for which the file was designed is unknown to Windows.

An application can combine these values to indicate that the file was designed for one operating system running on another. The following dwFileOS values are examples of this, but are 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 the Win32 API running on MS-DOS.
VOS_NT_WINDOWS32	The file was designed for the Win32 API running on Windows NT.
VOS_OS216_PM16	The file was designed for 16-bit Presentation Manager running on 16-bit OS/2.
VOS_OS232_PM32	The file was designed for 32-bit Presentation Manager running on 32-bit OS/2.

dwFileType

Specifies the general type of file. This member can be one of the following values:

Flag	Description
VFT_UNKNOWN	The file type is unknown to Windows.
VFT_APP	The file contains an application.
VFT_DLL	The file contains a dynamic-link library (DLL).
VFT_DRV	The file contains a device driver. If dwFileType is VFT_DRV, dwFileSubtype contains a more specific description of the driver.
VFT_FONT	The file contains a font. If dwFileType is VFT_FONT, dwFileSubtype contains a more specific description of the font file.
VFT_VXD	The file contains a virtual device.
VFT_STATIC_LIB	The file contains a static-link library.

All other values are reserved for future use by Microsoft.

dwFileSubtype

Specifies the function of the file. The possible values depend on the value of dwFileType. For all values of dwFileType not described in the following list, dwFileSubtype is zero.

If dwFileType is VFT_DRV, dwFileSubtype can be one of the following values:

Flag	Description
VFT2_UNKNOWN	The driver type is unknown by Windows.
VFT2_DRV_COMM	The file contains a communications driver.
VFT2_DRV_PRINTER	The file contains a printer driver.
VFT2_DRV_KEYBOARD	The file contains a keyboard driver.
VFT2_DRV_LANGUAGE	The file contains a language driver.
VFT2_DRV_DISPLAY	The file contains a display driver.
VFT2_DRV_MOUSE	The file contains a mouse driver.
VFT2_DRV_NETWORK	The file contains a network driver.
VFT2_DRV_SYSTEM	The file contains a system driver.
VFT2_DRV_INSTALLABLE	The file contains an installable driver.
VFT2_DRV_SOUND	The file contains a sound driver.

If dwFileType is VFT_FONT, dwFileSubtype can be one of the following values:

Flag	Description
VFT2_UNKNOWN	The font type is unknown by Windows.
VFT2_FONT_RASTER	The file contains a raster font.
VFT2_FONT_VECTOR	The file contains a vector font.
VFT2_FONT_TRUETYPE	The file contains a TrueType font.

If dwFileType is VFT_VXD, dwFileSubtype contains the virtual device identifier included in the virtual device control block.

All dwFileSubtype values not listed here are reserved for future use by Microsoft.

dwFileDateMS

Specifies the most significant 32 bits of the file’s 64-bit binary creation date and time stamp.

dwFileDateLS

Specifies the least significant 32 bits of the file’s 64-bit binary creation date and time stamp.

Remarks

The Value member of the VS_VERSION_INFO structure is a VS_FIXEDFILEINFO structure.
