Members

dwSignature

Type: DWORD

Contains the value 0xFEEF04BD. This is used with the szKey member of the VS_VERSIONINFO structure when searching a file for the VS_FIXEDFILEINFO structure.

dwStrucVersion

Type: DWORD

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

Type: DWORD

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

Type: DWORD

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

Type: DWORD

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

Type: DWORD

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

Type: DWORD

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

Type: DWORD

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

Value Meaning
VS_FF_DEBUG
0x00000001L
 The file contains debugging information or is compiled with debugging features enabled.
VS_FF_INFOINFERRED
0x00000010L
 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
0x00000004L
 The file has been modified and is not identical to the original shipping file of the same version number.

VS_FF_SPECIALBUILD
0x00000020L
 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.
