We learned last time that the SM_ CXCURSOR tells you the size the mouse cursor would have been in some hypothetical universe, which doesn’t really help you find out what the size of the cursor is in the current universe based in reality. This is, however, just a correlation there is no requirement that the two values be aligned with each other in any way. The SM_ CXICON system metric gives you the size of “standard” icons, which is loosely correlated with the size of the mouse cursor, in the sense that people who choose bigger icons tend also to choose bigger mouse cursors. They called GetSystemMetrics( SM_CXICON), but the value that was returned didn’t seem to be right. A customer wanted to know how to find out the size of the mouse cursor.
