I have a asp.net application where i use System.Windows.Forms namespace reference to use web browser control.the application runs fine on local system but after hosting it shows error. How do i embed the dll for to use in the web application.

Answer 1

Answering a 3 1/2 year old question is pretty weird...

I. In your web.config, add a reference to Windows.Forms

<system.web>
  <compilation>
    <assemblies>
      <add assembly="System.Windows.Forms, Version=4.0.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089" />
    </assemblies>
  </compilation>
<system.web>

This only works if the referenced DLL is in the GAC. If it is not:

1. Create a /Bin folder in your website root.
2. Copy your DLL there.
3. Do not add a reference in web.config.

II. In your module/class, import Windows.Forms (VB: Imports / C#: using)

Imports System.Windows.Forms

You can now use the web browser control. It's a bit tricky, though.

Possible uses include: generating screenshots, AJAX crawling (#! >> _escaped_fragment_) etc

Answer 2

System.Windows.Forms contains classes for displaying things on the computer that the code is running on. When you are testing on your PC, it works because you run the browser on the same machine as your development server.

When running on a real server, anything in System.Windows.Forms would be displayed on the server - not on the user's PC. (Besides it would be displayed on a hidden desktop in the server's service session).

You shouldn't mix webforms and windows forms. Whatever you want to do - there is another way that works, that doesn't involve winforms.

Don't use System.Windows.Forms in webb applications

Answer 3

As previously mentioned, you cannot use WinForms controls with ASP.NET.

Use an iframe to show whatever page you're trying to display in the webbrowser control: http://www.w3schools.com/tags/tag_iframe.asp

Answer 4

yes, you can do it,just copy the

system.window.form

dll into your web Bin Folder everything will work fine.
