Tooltips in Dialog Boxes

The editor for dialog templates (in Visual Studio 11), shows an option into the "Properties" panel. The name of the option is "Help ID" and the explanation is: "Assigns a help ID based on the resource ID to the control". Turning the option on has, obviously, no effect. Where shall I insert the text for the help? Is there any better way to associate a tooltip to controls in a dialog box?

Sample goes here. It's not about Help ID, it's just plain tooltip processing.

EDIT: In case you need this in MFC, just let me know.

Thanks a lot, this is all I needed. :wave:
