阅读更多关于 MFC : How to capture a link click event in a web browser control?

I have an MFC application that has a webcontrol. When clickable links are clicked, it opens using IE, not the default browser. Questions : Is there a way to force it to open using the default browser? If not, how do I capture the Link Click event so I could just manipulate the click event later? Thanks... No, not as far as I know. Check out the articles on http://ehsanakhgari.org/article/visual-c/webbrowser-goodies .

阅读更多关于 Required Property in Custom ASP .NET Control

I have a public property in the definition of my control that is required , if the user does not provide this property in the control definition on an ASP page it will break and we will get an exception. I want the compiler to throw a warning similar to the one when a user forgets to provide the 'runat' property of a Control.

阅读更多关于 Is it possible to add a web user control to a class library?

I'm looking at building some web user controls with an eye toward re-use, but I can't seem to add a Web User Control in my class library in VS2008. Is there a way to work around this problem, or is there a better approach to creating reusable controls? You can create either Web User Controls or Web Custom Controls that encapsulate the functionality you need. The main difference between the two controls lies in ease of creation vs. ease of use at design time. You should maybe consider creating a Web Custom Control library. There is a walkthrough for creating a web custom control using the Web
