How can I obtain the coordinates of where the mouse click occurred? Should I rely on a mouse event for this if there's such a thing? Any ideas?
For DxDesigner, handle the Application's MouseMoved event, which gives you the X and Y location, and the flags which tell the state of the mouse buttons and Ctrl/Shift/Alt keys. You may need to keep a copy of the flags on the previous MouseMoved event, to tell when the button goes from 0 to 1 (click-down) or 1 to 0 (click-up).
For Expedition, you can sink CommandListener events to handle specific mouse events.
