Re: Launch an application in an existing Form?

Yes, I saw that, the MSDN documentation is quite specific on that point.

The strange thing is that on the documentation from pinvoke.net
(http://pinvoke.net/default.aspx/user32/SetParent.html?diff=y) makes no
mention of this, and in their code sample actually launch notepad and
use SetParent on its main window.  There are probably certain cases
where this method isn't guaranteed to work, and Microsoft decided that a
simple "don't do it" is better than a lengthy explanation of where /
when you can use it (I think it's reasonable of them).

The documentation for SetParent does point out that "The new parent
window
and the child window must belong to the same application."

So, while it might appear to work, it's certainly not supported.
