Pointer-question.

[Fred Oxenby]

Perhaps you guys are fed up with pointer-question just now,
but I need to ask.
I am using "private messages" &H761A to &H761F to communicate
messages from my Runtime-DLL.
LParam is a pointer to a sting (the message)
Using a Dialog callback

Callback Function DlgCallBack
 Local Msg    As String Ptr
 Local MsgPtr As Dword
   MsgPtr = CbLparam
   If CbMsg = &H761A Then
     Msg = VarPtr(MsgPtr)
  
Why can't I just assign it like this:
  
  Msg = VarPtr(CBLParam)

Thanks for your help

You can't use VARPTR(CBLPARAM) as CBLPARAM acts more like a 'macro' than a real variable with a memory location.
