Hi Antonio,

Some suggestion of TWebView class.

Code: Select all  Expand view

CLASS TOB_WebView FROM TWebView
    DATA nDebug                    
    DATA nEval_TimeOut              INIT 15
    DATA nTimeOut_Step              INIT .25
    DATA oWndDlgContainer
    DATA oMsgBar1, oMsgBar2
    DATA lReadyStateControl     INIT .T.

    .....
    ......
    METHOD Eval( cScript )
    METHOD IsIdle()
    METHOD ReadData(cScript)
    .....
    .....
   
ENDCLASS


METHOD Eval( cScript, lSkipControl ) CLASS TOB_WebView
DEFAULT lSkipControl:=.T.
   
    IF !lSkipControl
        ::super:Eval( cScript )
    ELSEIF ::IsIdle()
        ::super:Eval( cScript )
    ELSE
        MsgAlert(cScript+CRLF+"TimeOut."+CRLF+"Please ("+NTRIM(::nEval_TimeOut)+" ) increase the TimeOut_Step.","Error")
    ENDIF
RETURN

/*
With Mr. Otto's suggestion.
*/
