I would like to create my own internet explorer with C#.
But what about cookies? Does my own internet explorer uses system integrated IE's cookies that I don't want to or it is clearly apart from system integrated IE's cookies?
The managed webbrowser control is just a managed wrapper around the native COM webbrowser control. Thus your browser will still use wininet and it will store cookies in the same place as IE.

I am using system.windows.forms.webbrowser in my Win forms application with IE as my default browser. Does the IE plugin/ Patch be applicable for my WebBrowser control?
No. If you read the document you will find that system.windows.forms.webbrowser is using embedded Internet Explorer regardless of what your default browser is.
AFAIK there is no built in way to use chrome as embedded browser in win form. You need a third party lib for that.
I'm creating a web browser that has an automatic loading of specific web pages, but the problem is that the browser that i created using c# in visual studio wont load javascipt, the browser that i created only load html file, but don't support java script. can anyone help me on how to add some functionality on my custom web browser that will support javascript.
WebKit DotNet is the best port of WebKit powerful browser engine into DotNetFramework.
It has nice and easy tutorials and properties and methods to customize.
It has JavaScript activated by default.
http://webkitdotnet.sourceforge.net/ is the official website.

Webbrowser control is really crappy. I'm assuming you're trying to scape some kind of website. For this use HttpWebRequest instead.
If you`re trying create your own webbrowser: don't, or use Webkit or Gecko instead.
In case you're using the webbrowser control you will have to enable JavaScript in your Internet Explorer settings, because the webbrowser control is the Internet Explorer or at least the engine of it. IE has local JavaScript disabled by default, so this could be your problem. As user #user3855678 said I would recommend using Webkit etc too.
can webserver recognize webbrowser control vs internet explorer software when user load page ?
if i load page through webbrowser control in c# i get "500 server error"
when i do it in the internet explorer software it work o.k.
why there is diffrent behevior and how i can manage that ?
thanking in advance.
That sounds like maybe it is reacting to a different cookie
value or similar. WebBrowser is IE (to most purposes). A 500 is at the server, but WebBrowser is the client.
You might be able to hook WebBrowser to supply a different user-agent, but by default it should appear the same.
How can i set the Windows Forms webbrowser control to block or allow cookies for the site it will navigate?
You can implement a Custom Security Manager and return URLPOLICY_DISALLOW in pPolicy for each kind of action between URLACTION_NETWORK_MIN and URLACTION_NETWORK_MAX. There are several actions for cookies. For a list of cookie related actions, check your zone security settings in IE options.
There are multiple webbrowser controls in .Net. The WPF one isn't customizable for this task. The Windows Forms one is kinda customizable however its IDocHostUIhandler implementation is stuck in internal code due to security guidelines of .Net BCL. You would be much better off if you use the raw ActiveX or its wrappers that support this kind of customization, e.g. csexwb. If you have to use the winform webbrowser control, you need to create your own webbrowser site.
The webbrowser control IS internet explorer. If you want to do this you may have to open an instance of the browser and block cookies through internet options. The webbrowser control itself doesn't provide a nice handy way to do that. Also doing this will block cookies from any site and not for a particular site
I am trying to migrate an .hta application to a C# executable. Of course, since it's an .hta the code is all HTML and Jscript, with calls to local ActiveX objects.
I created a C# executable project and am just using the WebBrowser control to display the HTML content. Simply renamed the .hta to an .html and took out the HTA declarations.
Everything works great, except that when I make calls to the ActiveX objects, I get a security popup warning of running an ActiveX control on the page.
I understand why this is happening since the WebBrowser control is essentially IE and uses the Internet Options security settings, but is there any way to get the WebBrowser control to bypass security popups, or a way to register the executable or DLLs as being trusted without having to change settings in Internet Options? Even a way to do on a deployment package would work as well.
WebBrowser is an instance of Internet Explorer, and inherits security settings from IE.
One way could be to change the security settings defined in IE.
The other way could be to add a Custom Security Manager by implementing IInternetSecurityManager interface.
The WebBrowser Control or MSHTML hosts could create a security manager (by implementing the IInternetSecurityManager interface) that handles the URL actions and policies that are important to the host. Other URL actions and policies would be passed to the default security manager so it could handle them appropriately. The IInternetSecurityMgrSite interface would be used to handle Windows-related information from the component so that the customized security manager could handle any user interface it required. -
