There are a few ways to track the position of the mouse cursor in Excel. However, if we want to react to mouse movement, we need to set a routine that monitors the position all the time and that’s very CPU-intensive. Another possibility is using one of Excel’s objects that allow mouse events. That’s the case of charts, for example, as well as ActiveX controls, among others. In this post we see how to use an ActiveX image in the background of the worksheet to capture mouse movement and follow the cursor position.
