Grab another window by handle and show it as a preview/video in my form (C#)
<p>So basically I am trying to capture the output of a render window that is hidden by default to put into a controller application as a preview. I've been told by some people in my line of work that this is possible by grabbing the window handle and somehow putting that as a video on your existing form. But I have no clue how to do that currently (outside of getting the handle itself)</p>

<p>Been looking all morning and a bit yesterday and haven't found exactly what I need yet.</p>

<p>Trying to do this in C#</p>
