msgbox when focus is lost on picturebox

how do i make it so when the mouse is not on a picturebox anymore, it gives the user a msgbox. i tried using the lostfocus function, but it doesnt seem to do anything.

How about the MouseMove event?

that's only when the mouse is still on the picturebox right? i tried that and did msgbox "hello", and it only pops up hello when it's ON it. how do i make it pop "HELLO" once it leaves the picturebox(i want to make a msgbox pop right away when the mouse leaves the picturebox)

VB Code:

Option Explicit
 
Private Declare Function SetCapture Lib "user32" (ByVal hwnd As Long) As Long
Private Declare Function ReleaseCapture Lib "user32" () As Long
Private Declare Function GetCapture Lib "user32" () As Long
 
Private Sub Picture1_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
If (X < 0) Or (Y < 0) Or (X > Picture1.Width) Or (Y > Picture1.Height) Then
       ReleaseCapture
       MsgBox "The mouse is no longer over the picture control"
ElseIf GetCapture() <> Picture1.hwnd Then
       SetCapture Picture1.hwnd
       'the mouse is over the picture control
       'if you want to do something when this happens
       'here is where you would put your code.
End If
End Sub

thanks so much
