What do or don't I set to keep a modeless dialog box OUT of the taskbar? The main window creates this box, which puts it's icon in the tray and in the ALT-TAB list. I need them OUT of there. (My other question is how did I do this before and can't now?) lol
you might try the WS_EX_TOOLWINDOW style.. not sure if that's what you're after, but it tends to keep things neat for me..
Give the dialog box an owner, any overlapped or popup window except the desktop. In your case, make the main window the owner.
