Hello,

I wrote this function that executes Javascript in the parent window, but it is not very reliable. For instance it works in www.bing.com but not in www.google.com. Any idea why?

HRESULT JS_InsertInline(wstring script)
{
	VARIANT vrt			= { 0 };		
	return win2->execScript(SysAllocStringLen(script.data(), script.size()), L"javascript", &vrt);
}

Any idea why? I tried using IHTMLScriptElement, but I have no idea how to do it in C++...


Regarding AJAX, the only thing I found was this. Not much information. Are there any examples or articles on how I could make an AJAX request from withing the function?


Thank you
