is there 开发者_如何学Pythona message that I can send to a window that will have the same effect as ShowWindow(SW_SHOW) or ShowWindow(SW_HIDE)

Is there a message that I can send to a window that will have the same effect as ShowWindow(SW_SHOW) or ShowWindow(SW_HIDE)?

No.

::SetWindowPos( window_handle, 0, 0, 0, 0, 0, ( visible ? SWP_SHOWWINDOW : SWP_HIDEWINDOW ) | SWP_NOMOVE | SWP_NOSIZE );

Did you try WM_SHOWWINDOW?

I'm not 100% sure if it will actually show/hide a window when posted, or whether it's only an "informative" hint to the application that this is happening, but it's worth a try.
