Message not found TFolder:TDialog in FWH 2026.03 and the same error in 2026.06

I'am using xHB com , xHarbour 1.2.3 Intl. (SimpLex) (Build 20190614)

best regard KAJOT

Dear Kajot,

• Fixed: TFolder crash "Message not found: TFOLDER:TDIALOG" with xHarbour
  xHarbour resolves ::Super based on the last CLASS..FROM seen in the file.
  TFolder:SetColor and SetDarkMode were defined after CLASS TFolderDialog
  FROM TDialog, so ::Super resolved to TDialog instead of TControl.
  Moved those methods before the TFolderDialog class definition.
  Also fixed deferred page creation: TFolder:New() now creates TFolderDialog
  pages even when parent hWnd is 0 (DEFINE DIALOG), so controls defined
  between DEFINE/ACTIVATE attach to the correct folder page.

You need an updated FWH build 👍🏻

I downloaded an FWH v.2026.06 once again and error is still

Please provide us a small PRG to check it

many thanks

Fix: Error BASE/1004 "No exported method: MOVE" en TFolder

El método AdjustRect() en source/classes/folder.prg intentaba llamar oDlg:Move() sobre elementos de ::aDialogs sin verificar si algún elemento es NIL.

Esto causaba un error fatal al iniciar un TFolder cuando el array ::aDialogs contenía entradas NIL (lo cual puede ocurrir normalmente según el flujo de inicialización).

Cambio: Se agregó una verificación de NIL tanto para ::aDialogs[1] antes de acceder a :nTop, como para cada oDlg dentro del AEval. Esto es consistente con el patrón ya usado en otros métodos de la misma clase (ej. línea 371).

Para mí, no supone ningún problema, ya que no he usado FOLDER durante muchos años. Actualmente solo utilizo el potente FOLDEREX, que funciona a la perfección.

Gracias, tks.
