vba 当触发KillTimer时，excel直接闪退了，连看代码出错的的时间都没有，敢问大神原因？


```Public Declare PtrSafe Function SetTimer Lib "user32" ( _
    ByVal HWnd As Long, _
    ByVal nIDEvent As Long, _
    ByVal uElapse As Long, _
    ByVal lpTimerFunc As LongPtr) As Long

Public Declare PtrSafe Function KillTimer Lib "user32" ( _
    ByVal HWnd As Long, _
    ByVal nIDEvent As LongPtr) As Long

Public Declare PtrSafe Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)

Public TimerID As Long
Public mymy As Integer
Sub StartTimer()
    TimerID = SetTimer(0&, 0&, 50&, AddressOf TimerProc)
    DoEvents
End Sub

Sub EndTimer()'触直接excel闪退
    On Error Resume Next
    KillTimer 0&, TimerID
End Sub
Sub TimerProc()
    mymy = mymy + 1
    Sheet1.Cells(5, 5) = mymy
End Sub

    参考：

    不要在vba/vb里使用带有回调函数的api（比如你这个addressof TimerProc），因为vba/vb缺乏异常处理机制，在回调中的异常会导致整个程序崩溃
