Developer Reference

TDllVersionInfo2 Type Definition
Record/structure, consisting of members/fields that provide extended information on the version of a dll.

Scope
Global (i.e. variables of this type can be declared in any unit that uses/includes the unit in which it is defined/declared).

Syntax
TYPE _DLLVERSIONINFO2 = RECORD info1 : DllVersionInfo; dwFlags : DWORD; ullVersion : INT64; END; TYPE DLLVERSIONINFO2 = _DLLVERSIONINFO2; TYPE TDllVersionInfo2 = DLLVERSIONINFO2; TYPE PDllVersionInfo2 = ^TDllVersionInfo2;

Members/Fields
info1	A record/structure of type TDllVersionInfo.
dwFlags	Reserved, double word/32-bit field.
ullVersion	A unsigned quadruple word (i.e. 64 bit), integer value that is a combination of the dll's major and minor versions, its build number and QFE number.

Values
In addition to the 5 double word values of the info1, TDllVersionInfo record, variables of this type can store a single, double word value and the quadruple word (i.e. 8 byte = 64 bit), compound version info in the dwFlags and ullVersion members/fields, or a total of 32 bytes.

Remarks
The cbSize member/field of the info1 member should be set to the size of the record/structure (in number of bytes) prior to passing a (pointer to a) variable of this type to DllGetVersion as a parameter.
The TDllVersionInfo2 record/structure is an extended version of the TDllVersionInfo, introduced with version 5.0 of ShlwAPI.dll (i.e. Internet Explorer 5.0 and/or Windows 2000/ME). Apart from the Quich Fix Engineering (QFE) number, it does not (really) provide any additional information on a dll's version, as the compound ullVersion memmber/field is generally used to encode a copy of the version info and buld number, already specified in the info1 record's members/fields.
