Draws the windowed control to a device context.
Call PaintTo to draw the control on a device context. Specify the device context as the value of the DC parameter and specify the X and Y coordinates on the device context where the top-left corner of the windowed control is to be drawn. PaintTo first erases the background of the device context and then paints the control.
PaintTo is useful for drawing an image of the control into a bitmap DC.
Warning: When using PaintTo to draw on a canvas, you must lock the canvas first (and unlock it after the call to PaintTo. If you do not lock the canvas, Windows calls that occur while the control is painting can cause the canvas to lose its handle.
