I have got two *.bmp's.
1) a background (about half screen size)
2) a red ball surrounded by black (for a transparent sprite)
I have really tried to display the ball on the background, but without success so far.
How can do this, please?

Thank you, WindowsKiller.
The ball does now appear on the background (a snooker table).

But:-
1) It appears as my original bitmap. That is, a black rectangle holding a red ball (i.e. it's not transparent).
2) The outline of the ball is no longer true. It is very jagged.

I have used this ball bitmap as a sprite in Liberty Basic and Visual Basic6 (boo!) and it works o.k.
Any ideas, please?

I think that I have now attached my bitmap (it's my first attachment).
I created it myself in MS Paint program using the ellipse/circle tool.

No, I copied and pasted your code snippet. The only changes I made were the names of my two bmp files.
This is a shot in the dark, but I have noticed that the jagged ball image which my program displays is approximately 1.3 times bigger than when I view it in Paint.
Is their any relevance in the fact that I have my resolution set at 800 X 600?

Thank you, I have now got a transparent sprite appearing on the background.
I am now going to work on the ball.bmp in the hope of getting its edges smooth.
I may be back.
