Question

WinForm程序如何将子窗体嵌入到父窗体的Panel里

Answer 1

主要通过SetParent实现：
[DllImport("user32.dll", EntryPoint = "SetParent")]
public static extern int SetParent(IntPtr hWndChild, IntPtr hWndNewParent);

MDIParent1 form = new MDIParent1();
SetParent(form.Handle, this.Panel1.Handle);
form.Location = new Point(0, 0);
form.Size = this.Size;
form.Show();
