Can I create an image map like in some websites in Delphi 4?
I'm making a virtual tour type program. So when someone clicks on one area
of an image the whole image is changed.

I can think of two different ways to do this:

1. Split your image into several "jigsaw" pieces and display them
all fitting nicely together. Your app would know exactly which image
section was clicked. This would be relatively easy, but you would
be limited to rectangular areas.

2. Create a bunch of regions that overlay your image (look up
CreateRectRgn and other similar functions). You then
perform hit testing in the mouse down event with the PtInRegion
function to see which region was clicked and perform the
appropriate action. You could outline the region by pmNotXOr - drawing
around that region, since you've already written the code that defines
the region.

The second method is more flexible and much more fun <g>

Track the OnMouseMove and keep the mouse coordinates.
Upon a OnMouseDown decide what to do : change the image...

Justin,

You may want to check out a book that was called something
like the Delphi Mulitimedia construction set , I think by
Coriolis, it has chapters dedicated to this exact probelm.
