Hi,

Messageboxes are not problem:
   PROCEDURE DirectCloseMessagebox()
      LOCAL ARRAY laWind(1)
      LOCAL lnCount,lii,lcCaption,liOwner,lcClass,liLen

      lnCount = AWINDOWS("laWind",1,_VFP.hwnd) && VFP2c32.fll
      FOR lii=1 TO lnCount
          lcCaption=GetWindowTextEx(laWind(lii))  && WINAPI

          liOwner=GetWindow(laWind(lii),GW_OWNER)  && WINAPI
          IF _VFP.hwnd=liOwner
             lcClass=SPACE(254)
             liLen=GetClassNameA(laWind(lii),@lcClass,LEN(lcClass))  && WINAPI
             IF liLen>0 AND LEFT(lcClass,liLen)=="#32770"
*                debugout lcCaption+" "+TRANSFORM(laWind(lii),"@0")+" "+TRANSFORM(liOwner,"@0")+" "+lcClass
                SendMessage(laWind(lii), WM_CLOSE, 0, 0)  && WINAPI
             ENDIF
          ENDIF   
      NEXT    
   ENDPROC
