Public Declare Auto Function SendMessageRef Lib "user32.dll" Alias
"SendMessage" (ByVal hWnd As IntPtr, ByVal Msg As Integer, ByVal
wParam As Integer, ByRef lParam As PARAFORMAT2) As Integer
PARAFORMAT2 is a structure that SendMessage will return stuff in.
Is the ByRef correct or since only a pointer is being passed should it be
ByVal?
Suppose I was passing data rather then receiving it,
would that change the answer to the above?
Thanks in advance
