The system tries to start an application on the monitor that contains its shortcut. The application displays the window on the primary monitor if the HMONITOR of a window is invalid. However, check that the position is still valid before using it because the monitor could have been moved or removed from the system. To save, and later restore, the position of a window when an application exits, use the GetWindowPlacement and SetWindowPlacement functions. However, a full-screen window covers the taskbar-for example, in Microsoft PowerPoint slide shows and games. Then use SetWindowPos to position and size the window to cover the monitor.Ī maximized window does not cover a taskbar that has the "Always on top" property. As an alternative, you could use the HMONITOR from the DirectX DirectDrawEnumerateEx function. To do this, the application must check what window it is on, using MonitorFromWindow or MonitorFromPoint, and then use GetMonitorInfo to get the size of the monitor. The size of a full-screen window needs to change as it moves among monitors with different resolutions. Also, use the GET_X_LPARAM and GET_Y_LPARAM macros to extract the coordinates, otherwise the sign of the coordinates may be wrong. To allow an appbar to be on any edge of any monitor, use the appropriate system metrics to calculate the edges of the monitors. Using SM_CXSCREEN and SM_CYSCREEN to determine the location of an application desktop toolbar (also called appbar) restricts the appbar to the primary monitor.

However, there can be a problem for custom menus, custom drop-down boxes, custom tool palettes, and the saved application position.įor an example of how to position objects correctly, see Positioning Objects on a Multiple Display Setup.

Windows automatically restricts menus and dialog boxes to a monitor. To center the dialog box to an application window, use GetWindowRect. To center dialog boxes in a window's work area, use the DS_CENTER style. Also, avoid SM_xxVIRTUALSCREEN because this centers your window on the virtual screen, not a monitor.

Note that SM_CXSCREEN and SM_CYSCREEN always refer to the primary monitor, not necessarily the monitor that displays your application. To get the coordinates for the monitor, use GetMonitorInfo, which provides both the work area and the entire monitor rectangle. To identify the monitor for a given point, rectangle, or window, use MonitorFromPoint, MonitorFromRect, and MonitorFromWindow. Typically, you will position an object either on the primary monitor or on a monitor that has an object already on it. Position the object using the coordinates.To position an object on a multiple monitor system For example, a window may need to be created on the same monitor as another window. If a window straddles two monitors and one of the monitors is repositioned, the system positions the window on the monitor that contains the largest part of the original window.Īn application will also typically need to position objects. If the dialog box has no owner and the active window is not in the same application as the dialog box, the dialog box appears on the primary monitor.Īppears on the monitor of the window that owns it. If it has no owner and the active window and the dialog box are in the same application, the dialog box appears on the monitor of the currently active window. The ALT-TAB key combination displays a window on the monitor that has the currently active window.Īppears on the monitor that contains the largest part of the corresponding menu item.Īppears on the monitor where the right click occurred.Īppears on the monitor that contains the rectangle of the combo box.Īppears on the monitor of the window that owns it.If it is defined with DS_CENTERMOUSE style, it appears on the monitor with the mouse. ObjectĬreateWindow(Ex) displays a window on the monitor that contains the largest part of the window.Maximizes on the monitor that contains the largest part of the window before it was minimized. The following table shows how the monitor is chosen. To minimize this problem, the system displays menus and new and maximized windows on one monitor. A window or menu that is on more than one monitor causes visual disruption for a viewer.
