The MouseMove event is generated continually as the mouse pointer moves across objects. Unless another object has captured the mouse, an object recognizes a MouseMove event whenever the mouse position is within its borders.Use the AnchorFromPoint property to retrieve the identifier of the anchor element from the point. The ValueFromPoint(X, Y) method returns information from the specified cursor position as a string, with items separated by new lines (\r\n), in the following order: value, inner-values, inner-value index / inner-values count, percent, index-serie, index-category, representing the value, serie, and category under the pointer. The CursorFromPoint(X, Y) method returns a string with information from the specified cursor position, items separated by new lines (\r\n), in the following order: x, y, and valueCategory, indicating the X-axis position, Y-axis value, and value in the cursor’s category under the pointer.

The following VB sample prints the cell's caption from the cursor ( if the control contains no inner cells. Use the SplitCell property to insert inner cells ) :

    X = X / Screen.TwipsPerPixelX
