Use PostMessage() instead:

Public Declare Function PostMessage Lib "user32" Alias "PostMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long

SendMessage() waits for the other app to process the message before returning back.
PostMessage() returns immediately after posting the message.
