QUESTION
I'm trying to play with a smart card using Windows 10/Access 2016 and VBA, and I have come across just about every example I could possibly find of how to make this happen, including:
- https://www.utteraccess.com/forum/Acccess-Card-Readers-t1986575.html
- Getting started with smartcard & ISO 7816 in excel vba ( SCardEstablishContext )
- https://docs.microsoft.com/en-us/windows/win32/api/winscard/ (for function reference), and
- Authentication Return Values and System Error Codes just to figure out what's going sideways.
The issue that I'm having is that SCardEstablishContext
is returning 0x0 - SCARD_S_SUCCESS
, but when I pass the SCARDCONTEXT over to SCardIsValidContext
, it's returning 0x6 - ERROR_INVALID_HANDLE
.
Here's the relevant parts of the code that I'm using (ignore AuthDict
and SCardAuthCode
as those are just helper functions to decode whatever status the other functions return)

is not a type, it's a handle. I don't know where that type comes from.
Use a LongPtr
for that handle.
SCardEstablishContext
uses a pointer to the handle, so ByRef
