IEFRAME Versions

IEFRAME.DLL was introduced for Internet Explorer 7 and Windows Vista, apparently by starting with extracts from SHDOCVW and BROWSEUI. It has so far existed in two variations considered by Microsoft to have sufficient external impact to deserve at least a difference in the minor version number.

Builds

Though the next table fusses over such details as build numbers and dates, it is certainly not meant as a comprehensive list even of builds that had formal, public releases. For that, consult Microsoft, who manufacture the software and are surely best able of anyone to present a definitive record. Bear in mind, however, that if Microsoft’s published documentation could sensibly be relied on as either comprehensive or accurate, then you could not now be reading these notes.

Builds are arranged in increasing order of the file version as recorded in the executable’s resources. This version number is readily visible using Windows Explorer either in a so-called infotip for the file or by accessing the Version tab in the Properties dialog for the file. Programmers know this version number as coming from the so-called root block of the version-information resource, specifically from the dwFileVersionMS and dwFileVersionLS members of a VS_FIXEDFILEINFO structure.

The date stamp shown for each version is more obscure. File dates are easily modified after the executable is built and are anyway liable to be shown differently when read from different time zones. However, there is in each executable’s header a date stamp which is set when the executable is built and is not commonly changed afterwards. It is readily accessible to anyone with programming knowledge and appropriate tools, e.g., Microsoft’s own DUMPBIN utility.

The executables for Windows Vista SP1 and Windows Server 2008 are identical.
