SurfaceCaps Structure

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

public final class SurfaceCaps extends ValueType

JScript suports the use of structures, but not the declaration of new ones.

Example

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 .NET Framework SDK.
'
' Called whenever the rendering device is created
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 .NET Framework 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);
}

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
