SAP OLE Automation Logon() method parameters

Question

I have been using RFC SAP logon through VBA for at least five years, but I still haven't found the meaning of logon's first parameter, whilst the second one for the dialog displaying is obvious. For the first I use 0 all the time.

Could somebody explain this?

Answer 1

This is handle of parent window HWND ParentWindow, here is the full method signature:

Logon (HWND ParentWindow, Boolean Silent)

Here is full list of properties of Logon object:

You can read the full guide of SAP Automation here, and the above info is on page 465.

In the guide only the second parameter is described (page 493) so probably first one is undefined or legacy, I think putting zero always will be just fine.
