12/1/93 Mike Duke Original module started as start for NT version of QRY
|
|
library.
|
|
|
|
$0006
|
|
miked: 2/17/1994
|
|
removed member ulRcSize from VIDEO_CHIP_INFO
|
|
|
|
$0004
|
|
miked: 1/26/1994
|
|
Added member ulRcSize to VIDEO_CHIP_INFO for getting the resource
|
|
size from the registry. Also revved the VIDEO_CHIP_INFO_VERSION
