I don't know what this
AppControl.ApplicationControl
component is. The SetParent API can be used to "embed" external application "into" an other form, like this:
public partial class Form1 : Form
{
[DllImport("user32.dll", SetLastError = true)]
static extern IntPtr SetParent(IntPtr hWndChild, IntPtr hWndNewParent);
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
Process p = new Process();
p.StartInfo.FileName = "Notepad.exe";
p.Start();
Thread.Sleep(50);
SetParent(p.MainWindowHandle, this.Handle);
}
}
But a hardware accelerated 3D application will certenly use an overlay, which can not be hosted this way.
