BaseMesh.LockVertexBuffer Method |
Language: |
Locks a vertex buffer and obtains a pointer to the vertex buffer memory.
Visual Basic .NET Public Function LockVertexBuffer( _
ByVal typeVertex As Type, _
ByVal flags As LockFlags, _
ByVal ranks() As Integer _
) As ArrayC# public Array LockVertexBuffer(
Type typeVertex,
LockFlags flags,
int[] ranks
);Managed C++ public: Array* LockVertexBuffer(
Type *typeVertex,
LockFlags flags,

);JScript .NET public function LockVertexBuffer(
typeVertex : Type,
flags : LockFlags,
ranks : int[]
) : Array;
typeVertex System.Type. A Type object that indicates the type of array data to return. This can be a value type or any type that contains only value types.
flags Microsoft.DirectX.Direct3D.LockFlags. Combination of zero or more LockFlags that describe the type of lock to perform. For this method, the valid flags are Discard, NoDirtyUpdate, NoSystemLock, ReadOnly, and NoOverWrite. For a description of the flags, see LockFlags. ranks System.Int32[]. Array of one to three Int32 values that indicate the dimensions of the returning Array
.
System.Array . An Array
that represents the locked vertex buffer.
When working with vertex buffers, multiple lock calls are allowed. However, the number of lock calls must match the number of unlock calls. Calls to Device.DrawPrimitives, for example, will not succeed with any outstanding lock count on any currently set vertex buffer.
Exceptions
InvalidCallException The method call is invalid. For example, a method's parameter might contain an invalid value.
