Why I can use Sendmessage to detect if text box changed but not Combobox. I did use EM_GetModify, but it does not work for combo. Please help

Public Const EM_GETMODIFY = &HB8
Public Const EM_SETMODIFY = &HB9
Public Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long
Public Declare Function PostMessage Lib "user32" Alias "PostMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long
Public Function isChanged(frm As Form)
Dim cntl
For Each cntl In frm
If SendMessage(cntl.hwnd, EM_GETMODIFY, True, True) Then
MsgBox "changed"
Exit Function
End If
Next
End Function
