In fact, it is simple to call two API functions.

1[DllImport ("User32.dll", EntryPoint ="SetParent")]2 Private Static externIntPtr SetParent (IntPtr hwndchild, IntPtr hwndnewparent);3  4[DllImport ("user32.dll", EntryPoint ="ShowWindow")]5  Public Static extern intShowWindow (INTPTR hwnd,intnCmdShow);

Call:

1Process p =NewProcess ();2p.StartInfo.FileName ="Cmd.exe";3P.startinfo.windowstyle = System.Diagnostics.ProcessWindowStyle.Minimized;//Set Program Style4 P.start ();5SetParent (P.mainwindowhandle, This. Handle);//Change the parent window handle of p to this program handle6ShowWindow (P.mainwindowhandle,3);//the first parameter window handle, and the second parameter specifies how the window is displayed

Parameter two API prototype:
sw_forceminimize: Minimizes the window in WindowNT5.0, even if the owning window's thread is suspended. This parameter is used only when minimizing windows from other threads.
sw_hide: Hides the window and activates other windows.
sw_maximize: Maximizes the specified window.
sw_minimize: Minimizes the specified window and activates the Next top-level window in the Z-order.
Sw_restore: Activates and displays the window. If the window is minimized or maximized, the system restores the window to its original size and position. When you restore the minimized window,ApplicationThis flag should be specified.
sw_show: Activates and displays the window in its original position at the original size.
Sw_showdefault: The display state is set according to the SW_FLAG flag specified in the STARTUPINFO structure, and the STARTUPINFO structure is passed to the CreateProcess function by the program that initiated the application.
sw_showmaximized: Activates the window and maximizes it.
sw_showminimized: Activates the window and minimizes it.
sw_showminnoactive: The window is minimized and the activation window remains active.
sw_showna: Displays the window in its original state. The activation window still remains active.
sw_shownoactivate: Displays the window with the last size and status of the window. The activation window still remains active.
Sw_shownormal: Activates and displays a window. If the window is minimized or maximized, the system restores it to its original size and size. This flag should be specified when the application displays the window for the first time.
