I am creating a c# piano which when clicking on a music key, an image of the music note is outputted on the form, however no image is being outputted. I am sure that the image path for the bitmap images is correct so I am not sure whether I have done something wrong in the code or I need to add some events to the form itself.Can somebody help me with this please ?
