object.GetVertexShaderConstant( _ 
    Register As Long, _ 
    ConstantData As Any, _ 
    ConstantCount As Long)

Parts

object

Object expression that resolves to a Direct3DDevice8 object.

Register

Register address at which to start retrieving data from the vertex constant array.

ConstantData

First element of an array to hold the retrieved values from the vertex constant array.

ConstantCount

Number of constants to retrieve from the vertex constant array. Each constant is comprised of four Single values.

Error Codes

If the method fails, an error is raised and Err.Number can be set to D3DERR_INVALIDCALL.

For information on trapping errors, see the Microsoft® Visual Basic® Error Handling topic.
