Conclusion
While this is a nice, easy example of the BitBlt function which is very important in skinning the method here is not very practical. This is because the form containing the picture has to stay open constantly and if it is moved beyond the screen or hidden from view, BitBlt will just copy whatever is obstructing it.
So there's your basic BitBlt API, while we've not done anything fancy in this tutorial the possibilities of the BitBlt API are enourmous.
