Okay so this will do what you want with less of an expense but just know mouse move does not update X,Y when over a control so it has intermittent issues with the event.
This is custom implementation of a mouseHover event using mouse move on the detail section so it is only called 1 time. It then loops through the controls (you can change this loop to only look at controls you want) and sees if the cursor is within 5 twips of the control on any side
It also accepts a fuzziness parameter because of the lack of updating when over a control. The default it 50 twips. Also know that the controls should be shrunk to the minimum size possible to fit the data as this function uses the controls height and width to determine if you are inside of the control.
Private Sub Detail_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
mouseHover X, Y
End Sub
Private Sub mouseHover(X As Single, Y As Single)
Dim ctrl As Control
'You may want to make an array of controls here to shorten the loop
'i.e.
' Dim ctrl_array() As Variant
' ctrl_array(0) = Me.lbl_projects_completed
' ctrl_array(1) = Me.some_other_label
' For Each ctrl in ctrl_array
For Each ctrl In Me.Controls
If ctrl.ControlType = acLabel Then
If FuzzyInsideControl(ctrl.top, ctrl.left, ctrl.width, ctrl.height, X, Y) Then
ctrl.FontBold = True
ctrl.ForeColor = RGB(255, 0, 0)
Exit For
Else
ctrl.ForeColor = RGB(0, 0, 0)
ctrl.FontBold = False
End If
End If
Next ctrl
End Sub
Private Function FuzzyInsideControl(top As Long, left As Long, width As Long, height As Long, X As Single, Y As Single, Optional fuzz As Integer = 50) As Boolean
Dim coord_left As Long
Dim coord_right As Long
Dim coord_top As Long
Dim coord_bottom As Long
Dim inside_x As Boolean
Dim inside_y As Boolean
coord_top = top - fuzz
coord_bottom = top + height + fuzz
coord_left = left - fuzz
coord_right = left + width + fuzz
inside_y = Y > coord_top And Y < coord_bottom
inside_x = X > coord_left And X < coord_right
FuzzyInsideControl = inside_x And inside_y
End Function
While I still think that this is unnecessary it was an interesting question and fun to work with but there are some of limitations due to how mouseMove works
Edit
Changed the FuzzyInsideControl function for a cleaner more concise version should be more accurate although I will have to test tomorrow when I get back to a computer with access.
