In the system above XP, the EDIT control supports the EM_SHOWBALLOONTIP message to display the balloon prompt.
Specific examples, if the file name is modified in the XP version of the resource manager, if the character set is not allowed in the file name, the balloon prompt is displayed.
I tried my own, creating a WTL dialog project, then added a listCtrl control, the EDIT control when the subcatenal ListCtr is renamed, can achieve the effect of the resource manager.
However, the message always returns false when creating the SHELL extension. It seems that Microsoft may have some restrictions in the resource manager.
