Delphi Are you familiar with “forgotten” hints? Here is a very rough example how to get rid of them…

Posted by jpluimers on 2018/05/22

Thanks for [WayBack] Are you familiar with “forgotten” hints? Here is a very rough example how to make them disappear without restarting the IDE… – Attila Kovacs – Google+

The code is centered around enumerating all windows of class TDesignerHintWindow and closing them.

These Windows happen to me a lot more in Galileo based IDEs than the classic Delphi < 8 ones.


EnumWindows(@EnumWindowsProc, LPARAM(0));
function EnumWindowsProc(Wnd: HWND; Form: TForm): BOOL; stdcall;
Buffer: array [0 .. 99] of Char;
ClassName: string;
GetClassName(Wnd, Buffer, 100);
ClassName := string(Buffer);
if ClassName = 'TDesignerHintWindow' then
SendMessage(Wnd, WM_CLOSE, 0, 0);
Result := True;
