Event fired when data is available without blocking.

public:
 int OnDataAvailable(System::UInt32 cElementsAvailable, int fIsComplete, System::UInt32 ulProgressCurrent, System::UInt32 ulProgressMax);

public:
 int OnDataAvailable(unsigned int cElementsAvailable, int fIsComplete, unsigned int ulProgressCurrent, unsigned int ulProgressMax);

int OnDataAvailable(unsigned int cElementsAvailable, int fIsComplete, unsigned int ulProgressCurrent, unsigned int ulProgressMax);

public int OnDataAvailable (uint cElementsAvailable, int fIsComplete, uint ulProgressCurrent, uint ulProgressMax);

abstract member OnDataAvailable : uint32 * int * uint32 * uint32 -> int

Public Function OnDataAvailable (cElementsAvailable As UInteger, fIsComplete As Integer, ulProgressCurrent As UInteger, ulProgressMax As UInteger) As Integer

Parameters

cElementsAvailable: UInt32

[in] Number of elements available to the consumer.

fIsComplete: Int32

[in] A Boolean parameter indicating completion (true) of the event.

ulProgressCurrent: UInt32

[in] Progress counter of elements served.

ulProgressMax: UInt32

[in] Maximum number of elements available.

Returns

Int32

If the method succeeds, it returns S_OK. If it fails, it returns an error code.

Remarks

The enumerator's behavior remains inherently synchronous, but as data is available without blocking OnDataAvailable() events are fired.

cElementsAvailable is always a delta. Pure progress information may be conveyed by the enumerator by passing 0 for cElementsAvailable and revised values for ulProgressCurrent and ulProgressMax.

COM Signature

From vsshell.idl:

HRESULT IVsAsyncEnumCallback::OnDataAvailable(  
   [in] ULONG cElementsAvailable,   
   [in] BOOL fIsComplete,   
   [in] ULONG ulProgressCurrent,   
   [in] ULONG ulProgressMax  
);
