请问红色部分代码是什么意思
如题:红色部分代码是什么运算,其他的消息怎么运算呢?
Public Function CallBackHookProc(ByVal nCode As Long, _
ByVal wParam As Long, _
ByVal lParam As Long) As Long
If nCode = HC_ACTION Then
Dim Msg As CWPSTRUCT
Call CopyMemory(Msg, ByVal lParam, Len(Msg))
If Msg.message = WM_COMMAND Then
If (Msg.wParam And &HFFFF0000) / &H10000 = EN_CHANGE Then
Debug.Print "GOTCHA"
End If
End If
End If
CallBackHookProc = CallNextHookEx(hHook, nCode, wParam, lParam)
End Function
