execute javascript in embedded web browser

[dvir.v...@gmail.com]

hi,

I generate the web browser classes (internet control).

one of the IWebBrowser2 class has getDocument() method.

I was wondering, how can I execute javacript method from getDocument() method.

do I have to generate the mshtml.dll ?

please help !!!

Hi Dvir,

Thank you for your question!

Here is a sample implementation of such functionality:

public String executeScript(final String function, final String param) { try { final Object[] rv = {null}; getOleMessageLoop().doInvokeAndWait(new Runnable() { public void run() { IDispatch documentDispatch = iWebBrowser2.getDocument(); IHTMLDocument document = new IHTMLDocumentImpl(documentDispatch); IDispatch script = document.getScript(); rv[0] = ((Variant) Automation.invokeDispatch(script, function, new Parameter[]{new Variant(param)}, Variant.class)).getValue(); System.out.println("rv = " + rv[0]); //Release COM interfaces as soon as we don't need them anymore script.setAutoDelete(false); script.release(); document.setAutoDelete(false); document.release(); documentDispatch.setAutoDelete(false); documentDispatch.release(); } }); if ((rv != null) && (!rv.toString().equalsIgnoreCase("null"))) { return rv.toString(); } } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } return null; }

Please let us know if you have any further questions on this particular case.

Best regards,
