Web Browser in .Net Form

I am having trouble converting this into a format that I can use in a
compiled .Net Jscript

The bottom line is that I am trying to incorporate a web browser control
inside a form.  This code was from Visual Studio and it works.

The problem has to do with the reference to web browser component.

The compiler complains that it can't find AxSHDocVw.  I have tried moving
the SHDocVw.dll into the directory and using:

jsc /r:shdocvw.dll test.js

Which does not cause an error, but still I can't get the proper reference to
the web browser component.

I have also tried import SHDocVw, which does not cause an error.

If it would be helpful, I will post the code I have that doesn't work. <g>

Thanks in advance.

Robbie

Robbie,

The code you posted is C#.  Are you trying to compile this with the
jsc.exe compiler?

The problem is he doesn't know how to reference the AsSHDocVw object in
Jscript.

The idea behind the post is to say:
This is how it is done in c#, how would you do it in .Net Jscript?

Robert,

Please ignore my other reply from earlier today.

For general information on how to host the ActiveX web browser
control from ShDocVw.dll, please go here:

http://samples.gotdotnet.com/quickstart/aspplus/default.aspx?url=%2fq
uickstart%2fwinforms%2fdoc%2fWinFormsAxHosting.aspx

Following the steps given on that page, here is one way to create a
simple browser-enabled JScript.Net app:

1.  Use the AxImp utility to create the .Net wrappers for the
ShDocVw.dll:

 aximp c:\winnt\system32\shdocvw.dll

Place the two output files (shdocvw.dll and AxShDocVw.DLL) in the
folder where your JScript.Net source code will go.

2.  Place the following JScript.Net code in a file named
"MainForm.js" in that folder:

import System;
import System.Drawing;
import System.Windows.Forms;

import AxSHDocVw;

Application.Run(new BrowserExample());

public final class BrowserExample extends Form
{
 var AxWebBrowser1 : AxSHDocVw.AxWebBrowser;
 
 public function BrowserExample()
 {
   this.Width = 400;
   this.Height = 400;
 
   this.AxWebBrowser1 = new AxSHDocVw.AxWebBrowser();
   this.AxWebBrowser1.BeginInit();
   this.AxWebBrowser1.Size = new System.Drawing.Size(292, 273);
   this.AxWebBrowser1.TabIndex = 3;
   this.AxWebBrowser1.Dock = System.Windows.Forms.DockStyle.Fill;
   this.Controls.Add(AxWebBrowser1);
   this.AxWebBrowser1.EndInit();
   
   this.AxWebBrowser1.Navigate("http://www.yahoo.com/");
 }
}

3.  Compile the application using this command line:

jsc /t:exe /r:system.dll /r:system.windows.forms.dll
/R:System.Drawing.DLL /R:shdocvw.dll /R:AxShDocVw.DLL mainform.js

I tried these steps with both .Net 1.0 and 1.1.  Everything worked OK
on my system.

Hope this helps.

Chris.
