问题 A browser helper object I'm writing at the moment needs to alert the user of certain situations. I don't want to use the WinAPI function MessageBox, because it forces the user to click it away. Is there a possibillity to ask the user a question without blocking his workflow? He should be able to just ignore the question, if he isn't interested in it at the moment. Something like gBrowser.getNotificationBox() for firefox extensions would be ideal (example image appended). 回答1: You can create

问题 My requirement is to develop a ActiveX control which can send the byte stream to serial port. The ActiveX control should expose only one function like SendData(char* data, int nLen, int nPort) This function should be able to be invoked by pressing a button developed in java rendered in Internet Explorer(both 32 and 64 bit). I am confused whether i should go with windowless ActiveX control using MFC/ATL or Browser Helper Objects. In future i may need to support Firefox also. Any help will be

问题 I have an IE BHO created over 3 years ago that uses IHTMLEventObj::put_keyCode function. This function has worked as documented in IE6, IE7 and IE8. However, when testing with IE9 RC it no longer works as documented. The function is called the same way and the result is S_OK, but the key does not show up in the input field. The call is being made in the DISPID_HTMLELEMENTEVENTS2_ONKEYPRESS even of my Invoke() function. I found someone with a similar problem: http://social.msdn.microsoft.com

I can get the <div> and its child <iframe> but fail to get the body. I get the frame collection from this API HRESULT IHTMLDocument2::get_frames(IHTMLFramesCollection2 **p); The problem can be re-created in igoogle and

问题 I have written a BHO and a toolbar for Internet Explorer in C#. They are getting installed and working properly. In the manage add-ons window in IE8, I am able to see both my BHO and toolbar.
