ConnectionService owns the fundamental connection setup, initializing workflows, and setting up channels

Public facing method that takes in handle requests, does handle management, and requests a connection Only one handle for each workflow can be requested at once. N+1 requests will throw InvalidOperationException

Name of workflow to start token handle to connection for the workflow

This method ensures that only one connection attempt occurs at once All other invocations will wait for the main connection attempt to succeed (or fail) and will adopt that result as well Exception is thrown (and standardized to ConnectionServiceException) if the connection attempt fails or times out

Token by caller for cancellation (e.g. cancel via Close) Task to wait for a connection attempt to complete

Actual logic to form a connection Underyling components throw if the connection attempt fails or times out

Correlation ID to pass around and to Android CancellationToken to cancel the operation Task to wait for a connection attempt to complete

This object adapts the Nano IClient interface to APC's IClientAdapter interface This gets a client which is already connected and maintains it. It also creates a message channel so communication is possible with the device. The message channel is for the invocation of workflows The client is the first recipient of any new channels created. It also monitors the connection (instability/close)

Waits for the client to finish setting up its internal objects Exceptions thrown: - TaskCanceledException - Close is called and current operations will be canceled - OperationCanceledException - Cancellation token passed into WaitForOpenAsync has been canceled

Cancellation token Returns when client has finished setting up internal objects

This object adapts the Nano IConnect interface to APC's IConnectAdapter interface This gets the local handshake request in InitializeAsync and uses the remote handshake response in OpenAsync

Initializes the p2p transport Exceptions thrown: - TaskCanceledException - Close is called and current operations will be canceled - OperationCanceledException - Cancellation token passed into InitializeAsync has been canceled - InvalidOperationException - Invalid call sequence

Returns connection string to be sent to peer for handshake

Using the peer's connection string, attempts to open a connection with the peer Exceptions thrown: - TaskCanceledException - Close is called and current operations will be canceled - OperationCanceledException - Cancellation token passed into InitializeAsync has been canceled - InvalidOperationException - Invalid call sequence - ConnectionServiceException - DirectConnectionTimedOut, Error, Canceled, Failed (unexpected), RemoteTransportTooOld, RemoteTransportTooNew

Peer's connection string Returns client object with open connection

IStateMachineWatcher listens for state changes and ensures that the target state machine does not get stuck in an unexpected state.

Initialize the watcher with a target state machine.

Target state machine Command to be issued if the state machine spends longer than the in an invalid state. Command details to be sent to the state machine if the timeout is reached Maximum time without any transition out of an invalid state. Exceeding the delay causes the watcher to timeout and issue the List of states which are not valid long running states. Exceeding the while in one of theses states will cause a timeout

If json[key] is a valid integer, parse the int and set it to value. Returns false if json[key] is not a valid int. Otherwise returns true.

This helps coordinate the request and response of messages where the request is fire and forget and a response comes another way. The relationship between the two messages is a transaction id. This helps connect the two together so the caller can expose an async method.

This starts a transaction and returns a Task that can be waited on for transaction compmletion.

AsyncTransaction that allows the caller to wait and get the transaction id

This completes the transaction. The task returned when the transaction was started is completed.

Unique id that links to the start of the transaction Value to return in the transaction

Supported is whether phone supports audio Enabled is whether PC has EXP enabled

whether audio code can run

This class is used to ensure that a single method will run just once However, it may run again if the method throws or the object is Reset One example of this class's use if there is a method that creates a connection. If there are multiple calls to create that connection from different sources, then only one thread should actually create the connection, while the other threads wait for that thread's completion before continuing This class is thread safe

Returns the current run task so callers can check status without invoking a run Returns null if there is no current task

Runs the single method if not yet run, or waits for a previous call to complete and returns on completion

Returns a task to wait for completion

Resets the object so that runs are canceled and threads are released

Identifies the dots per inch (dpi) setting for a monitor.

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.

The **HRESULT** data type is the same as the [SCODE](scode.md) data type. 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. A pointer to the IErrorInfo interface that provides more information about the error. You can specify to use the current IErrorInfo interface, or new IntPtr(-1) to ignore the current IErrorInfo interface and construct the exception just from the error code. , if it does not reflect an error.

Queries the dots per inch (dpi) of a display.

Handle of the monitor being queried. The type of DPI being queried. Possible values are from the MONITOR_DPI_TYPE enumeration. The value of the DPI along the X axis. 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.

Retrieves the bounding rectangle of the Windows taskbar.

Returns **TRUE** if successful; otherwise, **FALSE**. Note that this applies only to the system taskbar. Other objects, particularly toolbars supplied with third-party software, also can be present. As a result, some of the screen area not covered by the Windows taskbar might not be visible to the user. To retrieve the area of the screen not covered by both the taskbar and other app bars the working area available to your application , use the [**GetMonitorInfo**](/windows/desktop/api/winuser/nf-winuser-getmonitorinfoa) function.

The GetDeviceCaps function retrieves device-specific information for the specified device.

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.

Sends an appbar message to the system.

Type: DWORD Type: PAPPBARDATA A pointer to an APPBARDATA structure. The content of the structure on entry and on exit depends on the value set in the dwMessage parameter. See the individual message pages for specifics. Read more on docs.microsoft.com. Type: UINT_PTR This function returns a message-dependent value. For more information, see the Windows SDK documentation for the specific appbar message sent. Links to those documents are given in the See Also section.

Enables the specified process to set the foreground window using the SetForegroundWindow function. The calling process must already be able to set the foreground window. For more information, see Remarks later in this topic.

Type: DWORD The identifier of the process that will be enabled to set the foreground window. If this parameter is ASFW_ANY, all processes will be enabled to set the foreground window. 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. The function will fail if the calling process cannot set the foreground window. To get extended error information, call GetLastError. The system restricts which processes can set the foreground window. Normally, a process can set the foreground window by calling the [**SetForegroundWindow**](nf-winuser-setforegroundwindow.md) function only if: - All of the following conditions are true: - The calling process belongs to a desktop application, not a UWP app or a Windows Store app designed for Windows 8 or 8.1. - The foreground process has not disabled calls to **SetForegroundWindow** by a previous call to the [**LockSetForegroundWindow**](nf-winuser-locksetforegroundwindow.md) function. - The foreground lock time-out has expired (see [**SPI_GETFOREGROUNDLOCKTIMEOUT** in **SystemParametersInfo**](nf-winuser-systemparametersinfoa.md#SPI_GETFOREGROUNDLOCKTIMEOUT)). - No menus are active. - Additionally, at least one of the following conditions is true: - The calling process is the foreground process. - The calling process was started by the foreground process. - There is currently no foreground window, and thus no foreground process. - The calling process received the last input event. - Either the foreground process or the calling process is being debugged. A process that can set the foreground window can enable another process to set the foreground window by calling **AllowSetForegroundWindow**. The process specified by the *dwProcessId* parameter loses the ability to set the foreground window the next time that either the user generates input, unless the input is directed at that process, or the next time a process calls **AllowSetForegroundWindow**, unless the same process is specified as in the previous call to **AllowSetForegroundWindow**.

The MonitorFromPoint function retrieves a handle to the display monitor that contains a specified point.

A POINT structure that specifies the point of interest in virtual-screen coordinates. Determines the function's return value if the point is not contained within any display monitor. If the point is contained by a display monitor, the return value is an HMONITOR handle to that display monitor. If the point is not contained by a display monitor, the return value depends on the value of dwFlags. Learn more about this API from docs.microsoft.com.

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. Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see [Conventions for Function Prototypes](/windows/win32/intl/conventions-for-function-prototypes). Read more on docs.microsoft.com.

Retrieves the specified system metric or system configuration setting.

Type: int Type: int If the function succeeds, the return value is the requested system metric or configuration setting. If the function fails, the return value is 0. GetLastError does not provide extended error information. System metrics can vary from display to display. GetSystemMetrics(SM_CMONITORS) counts only visible display monitors. This is different from EnumDisplayMonitors, which enumerates both visible display monitors and invisible pseudo-monitors that are associated with mirroring drivers. An invisible pseudo-monitor is associated with a pseudo-device used to mirror application drawing for remoting or other purposes. The SM_ARRANGE setting specifies how the system arranges minimized windows, and consists of a starting position and a direction. The starting position can be one of the following values. This doc was truncated. Read more on docs.microsoft.com.

Retrieves the specified system metric or system configuration setting taking into account a provided DPI.

The system metric or configuration setting to be retrieved. See GetSystemMetrics for the possible values. The DPI to use for scaling the metric. 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. This function returns the same result as GetSystemMetrics but scales it according to an arbitrary DPI you provide if appropriate.

The GetDC function retrieves a handle to a device context (DC) for the client area of a specified window or for the entire screen.

A handle to the window whose DC is to be retrieved. If this value is NULL, GetDC retrieves the DC for the entire screen. If the function succeeds, the return value is a handle to the DC for the specified window's client area. If the function fails, the return value is NULL. The GetDC function retrieves a common, class, or private DC depending on the class style of the specified window. For class and private DCs, GetDC leaves the previously assigned attributes unchanged. However, for common DCs, GetDC assigns default attributes to the DC each time it is retrieved. For example, the default font is System, which is a bitmap font. Because of this, the handle to a common DC returned by GetDC does not tell you what font, color, or brush was used when the window was drawn. To determine the font, call GetTextFace. Note that the handle to the DC can only be used by a single thread at any one time. After painting with a common DC, the ReleaseDC function must be called to release the DC. Class and private DCs do not have to be released. ReleaseDC must be called from the same thread that called GetDC. The number of DCs is limited only by available memory. Read more on docs.microsoft.com.

The ReleaseDC function releases a device context (DC), freeing it for use by other applications. The effect of the ReleaseDC function depends on the type of DC. It frees only common and window DCs. It has no effect on class or private DCs.

A handle to the window whose DC is to be released. A handle to the DC to be released. The return value indicates whether the DC was released. If the DC was released, the return value is 1. If the DC was not released, the return value is zero. The application must call the ReleaseDC function for each call to the GetWindowDC function and for each call to the GetDC function that retrieves a common DC. An application cannot use the ReleaseDC function to release a DC that was created by calling the CreateDC function; instead, it must use the DeleteDC function. ReleaseDC must be called from the same thread that called GetDC. Read more on docs.microsoft.com.
