Syntax

'Declaration
Public Sub Present ( _
    rectPresent As Rectangle, _
    sourceRectangle As Boolean _
)
'Usage
Dim instance As SwapChain
Dim rectPresent As Rectangle
Dim sourceRectangle As Boolean

instance.Present(rectPresent, sourceRectangle)

public void Present(
    Rectangle rectPresent,
    bool sourceRectangle
)

public:
void Present(
    Rectangle rectPresent, 
    bool sourceRectangle
)

member Present : 
        rectPresent:Rectangle * 
        sourceRectangle:bool -> unit

Parameters

rectPresent
Type: System.Drawing.Rectangle
A Rectangle structure that contains the source rectangle. This value must be omitted unless the swap chain was created with Copy with a SwapEffect. If the value is omitted, the entire source surface is presented. If the rectangle exceeds the source surface, it is clipped to fit.

sourceRectangle
Type: System.Boolean
Set to true if a Rectangle is being passed to the rectPresent parameter; otherwise, false.

Exceptions

Exception	Condition
DriverInternalErrorException	Internal driver error. Applications should generally shut down when receiving this error.
InvalidCallException	The method call is invalid. For example, a method's parameter may contain an invalid value.
OutOfMemoryException	Direct3D could not allocate sufficient memory to complete the call.

Remarks

This method is a shortcut to Present for a Device. The swap chain method has been updated to include a flag that allows the application to request that the method return immediately when the driver reports that it cannot schedule a presentation.

If necessary, a stretch operation is applied to transfer the pixels in the source rectangle to the destination rectangle in the target window's client area.

The Present method of a Device fails if it is called between its BeginScene and EndScene pair; unless the render target is not the current render target such as the back buffer that results from the creation of an additional swap chain.
