Updating Resources on Win9x

Environment: Win9x

Windows NT contains some useful functions for updating resources in executables. Those are, however, not implemented on Windows 9x, so I had to write my own library for doing it. My library works in exactly the same manner as the BeginUpdateResource(), UpdateResource() and EndUpdateResource() API functions, just prepend an underscore to their names. It also provides a new function, _GetRsrcData(), which is used to get the resource data for a resource in a file loaded with _BeginUpdateResource().

The code works, at least on my system, but it has one major drawback: it can't move a section in memory. This means that if the .rsrc section would have to be expanded past its padding, _EndUpdateResource() will return ERROR_CANT_MOVE_SECTION unless .rsrc is the last section (both in the file and in VM space). This is a problem because VC6 puts the .reloc section (relocation info, used in DLLs and debug EXEs) after .rsrc, so you can't use the functions very well on those file types.

  • This ESG study by Mark Peters evaluated a common industry-standard disk VTl deduplication system (with 15:1 reduction ratio) versus a tape library with LTO-5, drives with full nightly backups, over a five-year period.  The scenarios included replicated systems and offsite tape vaults.  In all circumstances, the TCO for VTL with deduplication ranged from about 2 to 4 times more expensive than the LTO-5 tape library TCO. The paper shares recent ESG research and lots more. 

  • A global data storage provider whose business is booming needed a best-in-class data center to serve as the backbone of its technical operations going forward—and it needed it delivered within a year.
