Syntax

'Declaration

    rectPresent As Rectangle, _
    sourceRectangle As Boolean _
)
'Usage
Dim instance As Device
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
The Rectangle to present.

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.
DeviceLostException	The device is lost but cannot be reset at this time. Therefore, rendering is not possible.
InvalidCallException	The method call is invalid. For example, a method's parameter might contain an invalid value.

Remarks

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

This method fails and throws an InvalidCallException exception if it is called between BeginScene and EndScene pairs, 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.
