REMINDER: The goal is to setup everything automatically as much as possible. This means that when we get here for an existing cross-device user, we failed to live up to this promise. We now have to bother the user with something they already did in the past. This is not great. We should get out of the way as soon as we can. GOAL: Decide the fastest way to get the user to the PL experience. To do that, we need to decide what flow the user should follow. We start with a pending state to determine which of the following cases we start with: 1. No MSAs. We show ValueProp + Device Selection. No sign-in is visible. We prompt for sign-in only when the user selects Android. (AddADevice) 2. There is an MSA on the machine. a. If it is not enrolled and there are no devices associated with the MSA, or if we have an enrolled account and there are no devices, or this is an AddADevice flow: Show ValueProp + Device Selection and the MSA. (AddADevice) b. If it is not enrolled but there are devices associated with the MSA, we show the strong auth sign-in state (MsaContinue). c. If we have an enrolled account with devices associated, we jump immediately to the PL welcome experience. 3. There are multiple MSAs on the machine. Pick the first one and start with state 2.

An **HRESULT** value consists of the following fields: - A 1-bit code indicating severity, where zero represents success and 1 represents failure. - A 4-bit reserved value. - An 11-bit code indicating responsibility for the error or warning, also known as a facility code. - A 16-bit code describing the error or warning. Most MAPI interface methods and functions return **HRESULT** values to provide detailed cause formation. **HRESULT** values are also used widely in OLE interface methods. OLE provides several macros for converting between **HRESULT** values and **SCODE** values, another common data type for error handling. > [!NOTE] > In 64-bit MAPI, **HRESULT** is still a 32-bit value. For information about the OLE use of **HRESULT** values, see the *OLE Programmer's Reference*. For more information about the use of these values in MAPI, see [Error Handling](error-handling-in-mapi.md) and any of the following interface methods: [IABLogon::GetLastError](iablogon-getlasterror.md) [IMAPISupport::GetLastError](imapisupport-getlasterror.md) [IMAPIControl::GetLastError](imapicontrol-getlasterror.md) [IMAPITable::GetLastError](imapitable-getlasterror.md) [IMAPIProp::GetLastError](imapiprop-getlasterror.md) [IMAPIViewAdviseSink::OnPrint](imapiviewadvisesink-onprint.md) Read more on docs.microsoft.com.

All of these settings are affected by the PROCESS_DPI_AWARENESS of your application The effective DPI. This value should be used when determining the correct scale factor for scaling UI elements. This incorporates the scale factor set by the user for this specific display. The angular DPI. This DPI ensures rendering at a compliant angular resolution on the screen. This does not include the scale factor set by the user for this specific display. The raw DPI. This value is the linear DPI of the screen as measured on the screen itself. Use this value when you want to read the pixel density and not the recommended scaling setting. This does not include the scale factor set by the user for this specific display and is not guaranteed to be a supported DPI value. The default DPI setting for a monitor is MDT_EFFECTIVE_DPI. Specifies the FMTID/PID identifier that programmatically identifies a property. Replaces SHCOLUMNID. As of Windows Vista, the SHCOLUMNID structure is simply an alias for PROPERTYKEY, as shown in this declaration from Shobjidl.h. This doc was truncated. Read more on docs.microsoft.com. Type: GUID A unique GUID for the property. Read more on docs.microsoft.com. Type: DWORD A property identifier (PID). This parameter is not used as in SHCOLUMNID. It is recommended that you set this value to PID_FIRST_USABLE. Any value greater than or equal to 2 is acceptable.

This value always refers to the horizontal edge, even when the screen is rotated. The value of the DPI along the Y axis. This value always refers to the vertical edge, even when the screen is rotated. This function returns one of the following values. This doc was truncated. This API is not DPI aware and should not be used if the calling thread is per-monitor DPI aware. For the DPI-aware version of this API, see GetDpiForWindow. When you call GetDpiForMonitor, you will receive different DPI values depending on the DPI awareness of the calling application. DPI awareness is an application-level property usually defined in the application manifest. For more information about DPI awareness values, see PROCESS_DPI_AWARENESS. The following table indicates how the results will differ based on the PROCESS_DPI_AWARENESS value of your application. This doc was truncated. Read more on docs.microsoft.com. Closes an open object handle. A valid handle to an open object. If the function succeeds, the return value is nonzero. If the function fails, the return value is zero. To get extended error information, call GetLastError. If the application is running under a debugger, the function will throw an exception if it receives either a handle value that is not valid or a pseudo-handle value. This can happen if you close a handle twice, or if you call CloseHandle on a handle returned by the FindFirstFile function instead of calling the FindClose function. The CloseHandle function closes handles to the following objects: This doc was truncated. Read more on docs.microsoft.com. Enumerates all top-level windows on the screen by passing the handle to each window, in turn, to an application-defined callback function. EnumWindows continues until the last top-level window is enumerated or the callback function returns FALSE. Type: WNDENUMPROC A pointer to an application-defined callback function. For more information, see EnumWindowsProc. Read more on docs.microsoft.com. Type: LPARAM An application-defined value to be passed to the callback function. Read more on docs.microsoft.com. Type: BOOL If the function succeeds, the return value is nonzero. If the function fails, the return value is zero. To get extended error information, call GetLastError. If EnumWindowsProc returns zero, the return value is also zero. In this case, the callback function should call SetLastError to obtain a meaningful error code to be returned to the caller of EnumWindows. The EnumWindows function does not enumerate child windows, with the exception of a few top-level windows owned by the system that have the WS_CHILD style. This function is more reliable than calling the GetWindow function in a loop. An application that calls GetWindow to perform this task risks being caught in an infinite loop or referencing a handle to a window that has been destroyed.
Note  For Windows 8 and later, EnumWindows enumerates only top-level windows of desktop apps.

As part of the Vista re-architecture, all services were moved off the interactive desktop into Session 0. hwnd and window manager operations are only effective inside a session and cross-session attempts to manipulate the hwnd will fail. For more information, see The Windows Vista Developer Story: Application Compatibility Cookbook. If you have changed certain window data using SetWindowLong, you must call SetWindowPos for the changes to take effect. Use the following combination for uFlags: SWP_NOMOVE | SWP_NOSIZE | SWP_NOZORDER | SWP_FRAMECHANGED. A window can be made a topmost window either by setting the hWndInsertAfter parameter to HWND_TOPMOST and ensuring that the SWP_NOZORDER flag is not set, or by setting a window's position in the Z order so that it is above any existing topmost windows. When a non-topmost window is made topmost, its owned windows are also made topmost. Its owners, however, are not changed. If neither the SWP_NOACTIVATE nor SWP_NOZORDER flag is specified (that is, when the application requests that a window be simultaneously activated and its position in the Z order changed), the value specified in hWndInsertAfter is used only in the following circumstances.

Type: BOOL If the function succeeds, the return value is nonzero. If the function fails, the return value is zero. To get extended error information, call GetLastError. In conformance with conventions for the RECT structure, the bottom-right coordinates of the returned rectangle are exclusive. In other words, the pixel at (right, bottom) lies immediately outside the rectangle. GetWindowRect is virtualized for DPI. In Windows Vista and later, the Window Rect now includes the area occupied by the drop shadow. Calling GetWindowRect will have different behavior depending on whether the window has ever been shown or not. If the window has not been shown before, GetWindowRect will not include the area of the drop shadow. To get the window bounds excluding the drop shadow, use DwmGetWindowAttribute, specifying DWMWA_EXTENDED_FRAME_BOUNDS. Note that unlike the Window Rect, the DWM Extended Frame Bounds are not adjusted for DPI. Getting the extended frame bounds can only be done after the window has been shown at least once.

The DPI for the window, which depends on the [DPI_AWARENESS](/windows/win32/api/windef/ne-windef-dpi_awareness) of the window. See the **Remarks** section for more information. An invalid *hwnd* value will result in a return value of 0.

Type: BOOL If the specified window, its parent window, its parent's parent window, and so forth, have the WS_VISIBLE style, the return value is nonzero. Otherwise, the return value is zero. Because the return value specifies whether the window has the WS_VISIBLE style, it may be nonzero even if the window is totally obscured by other windows. The visibility state of a window is indicated by the WS_VISIBLE style bit. When WS_VISIBLE is set, the window is displayed and subsequent drawing into it is displayed as long as the window has the WS_VISIBLE style. Any drawing to a window with the WS_VISIBLE style will not be displayed if the window is obscured by other windows or is clipped by its parent window. Read more on docs.microsoft.com.

The MonitorFromWindow function retrieves a handle to the display monitor that has the largest area of intersection with the bounding rectangle of a specified window. A handle to the window of interest. Determines the function's return value if the window does not intersect any display monitor. If the window intersects one or more display monitor rectangles, the return value is an HMONITOR handle to the display monitor that has the largest area of intersection with the window. If the window does not intersect a display monitor, the return value depends on the value of dwFlags. If the window is currently minimized, MonitorFromWindow uses the rectangle of the window before it was minimized. The GetMonitorInfo function retrieves information about a display monitor. (Unicode) A handle to the display monitor of interest. A pointer to a MONITORINFO or MONITORINFOEX structure that receives information about the specified display monitor. You must set the cbSize member of the structure to sizeof(MONITORINFO) or sizeof(MONITORINFOEX) before calling the GetMonitorInfo function. Doing so lets the function determine the type of structure you are passing to it. The MONITORINFOEX structure is a superset of the MONITORINFO structure. It has one additional member: a string that contains a name for the display monitor. Most applications have no use for a display monitor name, and so can save some bytes by using a MONITORINFO structure. Read more on docs.microsoft.com. If the function succeeds, the return value is nonzero. If the function fails, the return value is zero. > [!NOTE] > The winuser.h header defines GetMonitorInfo as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant.
