clientY Property
Returns an Integer that represents the vertical position of the mouse pointer relative to the client area of the window, excluding window decorations and scroll bars.
expression.clientY
expression Required. An expression that returns one of the objects in the Applies To list.
Remarks
Since the clientY property returns a value relative to the client, you can add the value of the scrollTop property to determine the distance from the top edge of the BODY element.
Example
The following example displays a message that contains the horizontal and vertical position of the mouse pointer every time a user resizes the Microsoft FrontPage application window. This example must be placed in a class module, and it assumes you have declared an FPHTMLWindow2 object variable called "window."
Private Sub window_onresize()
Dim wEvent As IHTMLEventObj
Set wEvent = window.event
MsgBox "Your mouse is located at:" & vbCrLf & _
"Left: " & wEvent.clientX & vbCrLf & _
"Top: " & wEvent.clientY & vbCrLf & _
"Are you having fun?", vbYesNo
End Sub
