Parameters

adapter
Ordinal number that denotes the display adapter to query. AdapterListCollection.Default is always the primary display adapter.

deviceType
Member of the DeviceType enumeration that identifies the device type.

adapterFormat
Member of the Format enumeration that identifies the format of the display mode into which the adapter will be placed.

usage
Requested usage options for the surface. Usage options are any combination of Usage enumeration values (only a subset of the Usage values are valid for CheckDeviceFormat). For more information, see Usage .

resourceType
A ResourceType requested for use with the queried format.

checkFormat
Member of the Format enumeration that identifies the format of the surfaces that can be used, as defined by usage.

Return Value

true if the method succeeds; otherwise, false.

Example

The following code example shows how to determine whether a specific texture format is supported on a device.

' check support for a Format.A16B16R16F render target
If Not Microsoft.WindowsMobile.DirectX.Direct3D.Manager.CheckDeviceFormat(0, DeviceType.Default, Format.A1R5G5B5, Usage.RenderTarget, ResourceType.BackBuffer, Format.A1R5G5B5) Then
    MsgBox("Supported")
End If

// check support for a Format.A16B16R16F render target
if (!Microsoft.WindowsMobile.DirectX.Direct3D.Manager.CheckDeviceFormat(0, DeviceType.Default, Format.A1R5G5B5,
                                  Usage.RenderTarget, ResourceType.BackBuffer,
                                  Format.A1R5G5B5))
    MessageBox.Show("Supported");
