NiTroGen Posted September 20, 2007 Share Posted September 20, 2007 (edited) From the chm help, it says Limitations on COM Events in AutoIt Some Objects (like the 'WebBrowser') pass arguments to their Event Functions 'by reference'. This is intended to allow the user change these arguments and passing it back to the Object. However, AutoIt uses it's own variable scheme, which is not compatible to COM variables. This means that all values from Objects need to be converted into AutoIt variables, thus loosing the reference to the original memory space. Maybe in the near future we can solve this limitation for you ! So in case I really need to call a COM object event using ByRef. Any clues? eg. I want to block some URL opened by embedded IE by checking the url at BeforeNavigate event. Func IEEvent_BeforeNavigate($url, $Flags, $TargetFrameName, $PostData, $Headers, $Cancel) ;Many Checking code EndFunc **Adding "ByRef" before "$Cancal" won't work Any suggestions are welcome Edited September 20, 2007 by NiTroGen Link to comment Share on other sites More sharing options...
DaleHohm Posted September 20, 2007 Share Posted September 20, 2007 Best suggestion I have is to inject Javascript into the web page that does what you want.

NiTroGen Posted September 21, 2007 Author Share Posted September 21, 2007 @Dale Correct me if I am wrong. _IEHeadInsertEventScript seems working only after the page has been loaded completely. I plan to override the javascript function "window.open" before complete page loading. Any clue? Link to comment Share on other sites More sharing options...
DaleHohm Posted September 21, 2007 Share Posted September 21, 2007 Correct, _IEHeadInsertEventScript can't be used until the page is loaded. window.open typically would not happen until the page is loaded either however... what is invoking window.open?

NiTroGen Posted September 21, 2007 Author Share Posted September 21, 2007 I want to disable some javascript pop up when loading a page. Since autoit doesn't support COM ByRef variable, I can't cancel the popup by _IEEvent_Newwindow. Then I plan to override javascript window.open function instead.

DaleHohm Posted September 21, 2007 Share Posted September 21, 2007 (edited) From AutoIt directly I have no other ideas... Perhaps there is some way to get there indirectly with vb script: $oSC = ObjCreate("ScriptControl") $oSC.language = "VBScript" ; or Javascript (or perlscript...) $oSC.eval(VBScript-code) Dale Edit: typos Edited September 21, 2007 by DaleHohm Free Internet Tools: DebugBar, AutoIt IE Builder, HTTP UDF, MODIV2, IE Developer Toolbar, IEDocMon, Fiddler, HTML Validator, WGet, curl MSDN docs: InternetExplorer Object, Document Object, Overviews and Tutorials, DHTML Objects, DHTML Events, WinHttpRequest, XmlHttpRequest, Cross-Frame Scripting, Office object model Automate input type=file (Related) Alternative to _IECreateEmbedded? better: _IECreatePseudoEmbedded Better Better?
