If you read the winuser.h<\/tt> header file, you’ll see that the comments refer to accessible objects as “dudes”.<\/p>\n

\/*\r\n * For all EVENT_OBJECT events,\r\n *      hwnd is the dude<\/span> to Send the WM_GETOBJECT message to (unless NULL,\r\n *          see above for system things)\r\n *      ...\r\n *          The hwnd\/idObject pair gets you to the container, the dude<\/span> you\r\n *          probably want to talk to most of the time anyway.

What’s up with all of the “dude” references? Was  the person who wrote these comments<\/a> a fan of  The Big Lebowski<\/i><\/a>?<\/p>\n
There’s no connection as far as I’m aware.<\/p>\n
The term “dude” was a catch phrase in the Windows 95 window manager team, generally employed to mean “thing” or “entity”. It is common to see the word employed in this manner in internal comments:<\/p>\n
\/\/ Returns NULL or hMenu if top level dude\r\n\r\n\/\/ If the dude that has focus is a button, then...\r\n\r\n\/\/ Realloc the dude to the right size.\r\n\r\n\/\/ Is the caller a 32-bit dude?\r\n\r\n; lParam is the thread ID of the other dude.\r\n<\/pre>\n
The popularity of the term spread via cross-pollination to a few other teams, most notably the shell team, so you will see occasional mentions of “dude” in other parts of Windows 95. But most of them are in the window manager.<\/p>\n
Bonus chatter<\/b>: Outside of the window manager and closely-related teams, the term dude<\/i> can be found occasionally, but in those other places, it is used as a form of direct address, not as a placeholder noun:<\/p>\n
