Apart from the API I don't think the others will yield the mouse pointer co-ords which is how I read the question. Without looking at API's I came to the conclsion that it was not obvious. I tried a few properties but gave-up and found a different way of doing things like click events,
Form_OnMouseDown(button, X,Y) or something similar though if the click is in an object it fails. Look at OnMouse Over events - and fill the form with a picture box if necessary and use that as the carryer of the co-ords.
though there was a drag and drop thing I looked at - would this help? Click to set, drag an icon and click again to drop. I saw the code in the "samples" via a trial and error search in Help.
If see anything more useful when I get back to my machine I will post
