ShowWindow

The ShowWindow function sets the specified window's show state.

BOOL ShowWindow(
  HWND hWnd,     // handle to window
  int nCmdShow   // show state of window
);
 

Parameters

Handle to the window.

nCmdShow

Specifies how the window is to be shown. This parameter is ignored the first time an application calls ShowWindow, if theprogram that launched the application provides aSTARTUPINFO structure. Otherwise, the first time ShowWindow is called, the value should be the value obtained by the WinMain function in its nCmdShow parameter. In subsequent calls, this parameter can be one of the following values:
