/*
* ShowDriverSettings
* ShowDriverSettingsAfterFork
*
* When the user selects DevicesTab.<anydevice>.Properties.Settings, a
* DRV_CONFIGURE message is sent to the selected user-mode driver, to cause
* it to display its configuration dialog. The sound drivers shipped with
* NT (SNDBLST,MVAUDIO,SNDSYS) exhibit a bug in this condition: when the
* configuration dialog is complete (regardless of whether OK or CANCEL was
* selected), these drivers attempt to unload-and-reload their kernel-mode
* component in order to begin using the new (or restore the original)
* driver settings. The unload request fails, because both the Audio tab
* and SNDVOL.EXE have open mixer handles and pending IRPs within the kernel
* driver (the latter are used to provide notifications of volume changes).
* Worse, when the unload fails, it leaves the driver useless: its state
* remains STOP_PENDING, and it cannot be resurrected without logging off
* and back on.
*
* These routines have been provided as a temporary workaround for bug 15451,
* which describes the problem mentioned above. The theory behind this
* solution is two-fold:
* 1- close SNDVOL.EXE as soon as a driver's configuration dialog is
* to be displayed, and restart it directly thereafter. This prevents
* it from maintaining any open handles to and/or pending IRPs within the
* kernel driver.
* 2- if the Audio tab has ever been displayed, it will have open mixers
* which must be closed. Because a bug/design flaw within these sound
* drivers prevents the mixers from being closed without killing this
* process (the sound drivers each cache open mixer handles), the
* routine ShowDriverSettings forks a new MMSYS.CPL process, which is
* then used to display the driver's settings dialog.
*
* The flow of this solution follows:
*
* 1- MMSYS.CPL starts on Audio tab, setting fHaveStartedAudioDialog to TRUE.
* 2- User selects Devices tab.
* 3- User selects a device driver.
* 4- User selects Properties+Settings; control reaches ShowDriverSettings().
* 5- ShowDriverSettings() determines if there is a need to fork a new process:
* this will be the case if the Audio tab has been displayed, and the
* device for which it is to display settings contains mixers. If either
* of these conditions is false, ShowDriverSettings displays the driver's
* settings dialog directly (via ConfigureDriver()).
* 6- ShowDriverSettings() uses WinExec() to fork a new process, using
* the routine ShowDriverSettingsAfterFork() as an entry point. If the
* exec fails, ShowDriverSettings() displays the driver's settings dialog
* directly (via ConfigureDriver()).
* PROCESS 1: PROCESS 2:
* 7- Enters WaitForNewCPLWindow(), 1- ShowDriverSettingsAfterFork() will
* which will wait up to 5 seconds receive on its command-line the
* for the new MMSYS.CPL process name of the driver for which
* to open a driver Properties settings have been requested. It
* dialog which matches its own: opens the primary dialog, using the
* if it finds such a dialog, Devices tab as the initial tab--
* WaitForNewCPLWindow() will post so that the Advanced tab is never
* IDCANCEL messages to both the displayed, and because the Devices
* current driver Properties dialog, tab is the active tab on the other
* and to this process's main process.
* dialog, terminating this process. 2- During WM_INITDIALOG of the Devices
* dialog, this process searches for
* the previous process' MMSYS.CPL dialog.
* If successful, it moves this MMSYS.CPL
* dialog directly behind the previous dialog.
* 3- During ID_INIT of the Devices dialog, this
* process searches the TreeView for the driver
* which was named on the comand-line: if found,
* it highlights the TreeItem and simulates a press
* of the Properties button
* 4- During WM_INITDIALOG of the device's Properties dialog,
* this process searches for the previous process' device's
* properties dialog. If successful, it moves this dialog
* directly behind its counterpart.
* 5- During ID_INIT of the device's Properties dialog, this process
* simulates a press of the Settings button
* 6- When the Settings button is pressed, this process recognizes that
* it has been forked and skips the call to ShowDriverSettings(),
* instead simply displaying the driver's settings dialog (via
* ConfigureDriver()).
*
* Let it be known that this is a hack, and should be removed post-beta.
