Is there any way to get the font size of the currently selected text in the Microsoft WebBrowser control (MSHTML)? I am aware of IHTMLDocument2::queryCommandState("FontSize", ...), but this method only returns a value between 1 and 7, for the outdated font sizes "xx-small" to "xx-large". For font sizes like "10pt" or "14px", no useful v...

Is there any way to remove a CSS attribute/declaration that has already been rendered on an element? For example, if I'm using a CSS reset stylesheet to set the margin on images to 0, I can no longer use hspace or vspace values (yes, I know they're deprecated in HTML 4+). Is there a way to remove this declaration so the browser renders...

I don't see any way to tell the webbrowser control to load the BHO. The BHO doesn't show any GUI or anything, it just listens to the http traffic when used fro...
I have been googling for hours and trying to figure this out, and I just can't. I have 1 webbrowser control on a form, webbrowser1. Once I load a page, say google.com, if I use webbrowser1.refresh() or webbrowser1.navigate("google.com"), it's not reloading the page, it has it cached so it's just reloading the cache. This is terribly appa...
I just found out that to simulate a click I can call element.InvokeMember("click"); where element is an HtmlElement. But what I actually need is to open the link in a new window, but not on the default browser but on another WebBrowser I would create in my program. Sometimes it works to just get the href attribute by calling element.GetA...

For one of our desktop applications we use a HTML-based interface, loaded from local files into a WebBrowser control. This works fine, but now we want to load the files from a different source, and are trying to stream them in using IPersistStreamInit (like this example on MSDN). It seems to work OK, except for the referenced javascrip...

So I'm running a Windows Service as a user. Admin rights. This service launches an EXE via Process.Start. Within the EXE, a WebBrowser control is used to navigate to a website, log in, handle all the security handshaking, and get some data. It comes back out, writes the data to a file. Not the most efficient process, admittedly, but...
