Native Variante the idea of Andreas Miethe, with this Variant the FastMode not necessary but xpse:
CompileMarkSeparation
Declare Brush&
cls
var hDlg&=createDialog(%hWnd,"Hallo Welt",300,300,500,400)
Brush&=CreateSolidBrush($6CB6FF)
setWindowLong(hDlg&,gwl_wndProc,procAddr(myDlgProc,4))
redrawWindow(hDlg&,NULL, NULL, RDW_INVALIDATE | RDW_ERASE )

While 1

    WaitInput

EndWhile

nProc myDlgProc

    Parameters Wnd&,Msg&,WParam&,LParam&
    Global Brush&
    case Msg& = wm_ctlColorDlg : return Brush&
    Return DefDlgProc(Wnd&,Msg&,WParam&,LParam&)

ENDPROC
