Keep Messagebox.show() on top of other application using c#

Question

How to keep a Messagebox.show() on top of other application using c# ??

Answer 1

There's a better solution, without creating a new form.

MessageBox.Show("Message Text", "Header", MessageBoxButtons.OK, MessageBoxIcon.None, 
     MessageBoxDefaultButton.Button1, (MessageBoxOptions)0x40000);  // MB_TOPMOST

The 0x40000 is the "MB_TOPMOST"-Flag.
