Set window to full screen but showing the task bar

Question

Hi!

I'm developing a Windows 10 and Windows 11 application with C++.

I want to run an application in full screen mode, but showing the task bar.

Is there a way to do it programmatically?

Thanks.

[the forum for Win32 API is https://learn.microsoft.com/en-us/answers/tags/224/windows-api-win32]

You can do for example :

				RECT rect;
				SystemParametersInfo(SPI_GETWORKAREA, 0, &rect, 0);
				SetWindowLong(hWnd, GWL_STYLE, WS_POPUP | WS_VISIBLE | WS_MINIMIZEBOX);
				SetWindowPos(hWnd, NULL, 0, 0, rect.right - rect.left, rect.bottom - rect.top, SWP_NOZORDER);

You can create a full-screen window using the CreateWindowEx function with the WS_POPUP style, which removes the window frame, and WS_VISIBLE to make it visible. The window size is set to match the screen resolution using GetSystemMetrics.
