This is possible but if the other program isn’t expecting its top-level window to be embedded in another window then it may cause problems. VLC in particular fully expects you to embed its video output window within your own window, and provides an API to do it on all supported platforms. Doing the same for a different program that isn’t expecting it will require digging into the platform’s API

Code conversion (Delphi)

Kinda sorta almost works: //Window.Open Declare Function ShellExecuteW Lib "Shell32" (HWND As Integer, op As WString, file As WString, params As WString, directory As WString, cmd As Integer) As Integer Const SW_HIDE = 0 If ShellExecuteW(Self.Handle, "open", "notepad.exe", "", App.ExecutableFile.Parent.AbsolutePath, SW_HIDE) <= 32 Then MsgBox("Failed to launch") Return End If Declare Function FindWindowW Lib "User32" (ClassName As WString, WindowName As WString) As Integer Dim HWND As…

It uses the Windows API function SetParent to create the parent/child relationship between the two windows and SetWindowPos to set the child window’s coordinates and size to match the parent.
