BPCSuspend.DeviceRelease

The DeviceRelease method causes the Video Access server to attempt to release all devices. Visual Basic syntax is shown.

object.DeviceRelease(lPriority, pps)

Parts

object

Object expression that resolves to a BPCSuspend object.

lPriority

Reserved. This value should be set to zero.

pps

Reference to a BPCSuspended object. If the Video Access server successfully releases all devices, the pps parameter contains a reference to a valid BPCSuspended object. Otherwise, pps contains Nothing.

Remarks

Your application should not use the BPCSuspend or BPCSuspended class while it is in a state in which cross-process COM calls are disallowed. For example, if your application is currently processing a call to the Win32 SendMessage function or a broadcast system message any cross-process COM calls fail with an RPC_E_CANTCALLOUT_ININPUTSYNCCALL error code. If your application is in such a state when it attempts to suspend the Video Access server, the running object table can become corrupt and lock up the server.
