自己写了一个控件，想实现MouseIn/MouseOUt事件
利用SetCapture和ReleaseCapture来实现的

在调试时,如果在控件的MouseIn代码中加入
MsgBox "I'm IN"
则原控件中的MouseOut事件不会再被触发了

''''控件代码实现部分
Public Declare Function SetCapture Lib "user32 " (ByVal hwnd As Long) As Long
Public Declare Function ReleaseCapture Lib "user32 " () As Long

Public Event MouseIn()
Public Event MouseOut()
............
Private Sub Text1_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
        If X > 0 And X < Text1.Width And Y > 0 And Y < Text1.Height Then
                SetCapture Text1.hwnd         '鼠标捕获
                Text1.BackColor = vbRed
                RaiseEvent MouseIn
                Debug.Print "IN"
        Else
                Text1.BackColor = vbWhite
                ReleaseCapture                     '释放鼠标捕获
                RaiseEvent MouseOut
                Debug.Print "OUT"
        End If
        
End Sub
不知有什么好的解决方案不?

多谢 问题确实如你的方法解决了
