Restoring parent from the desktop window

Question

I've imported:

public static extern IntPtr SetParent(
        IntPtr hWndChild,      // handle to window
        IntPtr hWndNewParent   // new parent window
    );

from user32.dll in my windows forms application and continuously setting SetParent(hwndf,hwndParent); (if a variable is true) in a background thread.

Where

IntPtr hwndf = Control.Handle;
IntPtr hwndParent = FindWindow("ProgMan", null);

My question How do i reset the parent handle to be the default windows form handle, aka, how do I not display the window on top of the desktop window anymore? and is following, Is this an efficient way of doing this (repeatedly?).

Answer 1

Never mind. I could just use

SetParent(hwndf, new IntPtr(0));

When I wanted to "reset" the form window parent. The only problem was the the window was minimized, so my solution was running ShowWindow(hwndf, SW_RESTORE); after importing these methods from user32.dll!

    [DllImport("user32.dll")]
    public static extern IntPtr ShowWindow(
        IntPtr hWnd,      // handle to window
        uint nCmdShow
    );
    private const uint SW_RESTORE = 0x09;
