问题 I have run into this "BitBlt" from time to time in my searched, but i don´t get how to use it. From what people say, it seems to be the fastest way to capture a screen that Windows show.

问题 I am working on a project which runs on .NET 2.0. My task is to recreate the data displayed in HTML as a prinatable image (with the resolution of at least 150dpi).

问题 Currently, I'm printing the contents of a WPF WebBrowser like so: mshtml.IHTMLDocument2 doc = WebBrowser.Document as mshtml.IHTMLDocument2; doc.execCommand("Print", true, null); My HTML content has tables with background colors.
