SurfaceCaps Structure

[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]

Represents information about surface capabilities.

Namespace:  Microsoft.WindowsMobile.DirectX.Direct3D
Assembly:  Microsoft.WindowsMobile.DirectX (in Microsoft.WindowsMobile.DirectX.dll)

Syntax

'Declaration
Public Structure SurfaceCaps
'Usage
Dim instance As SurfaceCaps
public struct SurfaceCaps
public value class SurfaceCaps
[<SealedAttribute>]
type SurfaceCaps =  struct end

Examples

The following code example shows how to use a SurfaceCaps structure.

' This code example is taken from the
' Direct3D Mobile Texture Sample of the
' .NET Compact Framework Samples in the SDK.
'
' Called whenever the rendering device is created
Private Sub OnCreateDevice(ByVal sender As Object, ByVal e As EventArgs) 
    Dim vertexBufferPool As Pool
    Dim caps As Caps
    Dim dev As Device = CType(sender, Device)

    ' Get the device capabilities
    caps = dev.DeviceCaps

    If caps.SurfaceCaps.SupportsVidVertexBuffer Then
        vertexBufferPool = Pool.VideoMemory
    Else
        vertexBufferPool = Pool.SystemMemory
    End If 
    ' Now create the vertex buffer
    vertexBuffer = New VertexBuffer(GetType(CustomVertex.PositionNormalTextured), 100, dev, Usage.WriteOnly, CustomVertex.PositionNormalTextured.Format, vertexBufferPool)
    AddHandler vertexBuffer.Created, AddressOf Me.OnCreateVertexBuffer
    Me.OnCreateVertexBuffer(vertexBuffer, Nothing)

End Sub

// This code example is taken from the
// Direct3D Mobile Texture Sample of the
// .NET Compact Framework Samples in the SDK.

// Called whenever the rendering device is created
void OnCreateDevice(object sender, EventArgs e)
{
    Pool vertexBufferPool;
    Caps caps;
    Device dev = (Device)sender;

    // Get the device capabilities

    caps = dev.DeviceCaps;

    if (caps.SurfaceCaps.SupportsVidVertexBuffer)
        vertexBufferPool = Pool.VideoMemory;
    else
        vertexBufferPool = Pool.SystemMemory;

    // Now create the vertex buffer.
    vertexBuffer = new VertexBuffer(
        typeof(CustomVertex.PositionNormalTextured), 100, dev,
        Usage.WriteOnly, CustomVertex.PositionNormalTextured.Format,
        vertexBufferPool);
    vertexBuffer.Created += new System.EventHandler(
        this.OnCreateVertexBuffer);
    this.OnCreateVertexBuffer(vertexBuffer, null);
}
