What's the difference?For the life of me, I can't figure out what.Thanks

Help Ids give static information (pre-CFS2), tooltip show also some dynamic info like associated values. Tooltips were introduced with CFS2 if I recall that right.Arne Bartels

Ok, then I'm not crazy :) I thought they really might be just an extension of the technology. Yeah!

HelpIDs are the old style tooltips that were compiled as resources in FS, so you cannot change them.The new tooltips however can be dynamic (have parameters) or static. The macros must be enclosed in mouse_parent blocks.For an example of a static tooltip:MOUSE_BEGIN....MOUSE_PARENT....MOUSE_TOOLTIP_STRING ("Tooltip string goes here")MOUSE_CHILD_FUNCTION...MOUSE_PARENT_ENDMOUSE_PARENT....MOUSE_TOOLTIP_STRING ("Another tooltip string goes here")MOUSE_CHILD_FUNCTION...MOUSE_PARENT_ENDMOUSE_ENDFor an example using parameters, lookup the tooltip sample in the SDK documentation.
