Acrobat implements an ActiveX control that IE loads to display pdf
files.  It does not load the main Acrobat application and then
position it inside the IE window.  The ActiveX control handles the
display internally.

Unless those applications implement their own containable ActiveX
controls like Adobe does, then your only option is to start an
application, then manually find its window(s), such as with
EnumWindows() and GetWindowThreadProcessId() (use CreateProcess()
instead of ShellExecute() in order to get the thread and process IDs
of the application), and then use SetParent() to manually set them as
children for your own UI window.

That is not what the hwnd parameter of ShellExecute() is for.
