Hi,

I have a application that I need to create multiple new "iexplore.exe"
processes (show more than once in taskmanger) and control them using the
shdocvw/mshtml.

I am able control Internet Explorer with instances created with the shdocvw.
e.g.
Activator.CreateInstance(Type.GetTypeFromProgID
("InternetExplorer.Application");

And I am able to create the new "iexplore.exe" processes. e.g.
System.Diagnostics.Process.Start("iexplore.exe");

The problem I am having is creating the Internet Explorer with
Process.Start() and being able to control it using the shdocvw/mshtml
libraries.

Is there a way I can use the process id of the started "iexplore.exe" and
turn it into the IWebBrowser2 interface?

Many thanks in advance

Adam
 
Hi,

First, sorry for a rather vague answer. From what I remember, there is a
custom window message allowing to obtain the Web browser interface when
being sent to an IE window. So your task will be to determine one of the
top-level windows of an "iexplore.exe" instance in question, and then to
send the custom message to that window, obtaining a 32-bit pointer to the
interface and then marshalling it to the managed space. So I welcome experts
on interop and IE to add necessary details!
 
I am also open to suggestion on how I could create a new "iexplore.exe"
process by using the shdocvw library, if this is at all possible.

Regards

Adam
 
The reason I need to create separate processes is due to session cookies, is
there a way to clear these on each navigate?
 
I have managed to find a solution to my problem. Here is my solution.

Process m_Proc = Process.Start("IExplore.exe");

InternetExplorer m_IEBrowser = null;
ShellWindows m_IEFoundBrowsers = new ShellWindowsClass();
foreach(InternetExplorer Browser in m_IEFoundBrowsers)
{
if(Browser.HWND == (int)m_Proc.MainWindowHandle)
{
m_IEBrowser = Browser;
break;
}
}
