I am considering a situation where I have (n) number of form windows, each

each web browser control is an HTML page that has a Java applet. This is the
only way I am aware of to get a Java applet to paint within a .NET Forms
window.
It's the only way that I know of too... though I'm a little surprise no one
has written at least an ActiveX wrapper to accomplish this.... I guess
there's never been much of a need. I would rather use a simple ActiveX
wrapper even in .NET than use the full blown Webbrowser control to host a
Java applet.
Given that scenario I am trying to determine whethere there would be one
Java VM loaded for all of the (n) applets inside the (n) MS Web Controls? Or
would there be one Java VM loaded for each applet?
Only one VM is loaded.
Also, if using IE6, what
JVM is being used? Microsoft's or Sun's?
Whichever one is registered. If you install Sun JRE it installs itself as
the default supplanting MS's implementation.
Also, are there any thoughts on what overhead there would be in having
multiple instances of the MS Web Control? I am expecting upwards of 10-15 as
a worst case.
Not much more overhead than running IE normally. They'll all run in your
singular process. HOWEVER, beware that the Webbrowser control behaves a
little funky in .NET. For instance if you load a form that contains a
Webbrowser control and you don't show the window at least once, you get a
"handle not created" error when you dispose of the form. This makes putting
the Webbrowser control on tab pages and stuff like that a little error prone.
