Locks, sets, and unlocks a range of vertex data.

Definition

Visual Basic Public Sub SetData( _
    ByVal data As Object, _
    ByVal lockAtOffset As Integer, _
    ByVal flags As LockFlags _
)

C# public void SetData(
    object data,
    int lockAtOffset,
    LockFlags flags
);

C++ public:
void SetData(
    Object^ data,
    int lockAtOffset,
    LockFlags flags
);

JScript public function SetData(
    data : Object,
    lockAtOffset : int,
    flags : LockFlags
);

Parameters

data System.Object
An Object that contains the data to copy into the vertex buffer. This can be any value type or any type that contains only value types.

lockAtOffset System.Int32
Offset in the vertex buffer to set. To set the entire buffer, set this parameter to 0.

flags Microsoft.DirectX.Direct3D.LockFlags
Zero or more LockFlags locking flags that describe the type of lock to perform when setting the buffer. For this method, the valid flags are Discard, NoDirtyUpdate, NoSystemLock, ReadOnly, and NoOverWrite. For a description of the flags, see LockFlags.

Remarks

The Lock.Discard and NoOverWrite flags are valid only on buffers created with Dynamic.

Exceptions

InvalidCallException

The method call is invalid. For example, a method's parameter might contain an invalid value.
