--- Comment #6 from Andrew Nguyen arethusa26@gmail.com 2010-05-25 16:12:06 --- I'm not seeing your failure. I did:
1. Starting with a clean Wine prefix, and winetricks from SVN, execute winetricks -q mdac28 jet40. 2. Copy the Northwind sample database to the directory where the compiled ado1b.exe file is, naming it stock.mdb.
I get (snipping out irrelevant "no class object" messages):
ADODB Object created CallMethod entered GetIDsOfNames returned Invoke 'Open' succeeded ADODB connection opened CallMethod entered GetIDsOfNames returned Invoke 'Close' succeeded Close down
So the sample should be working as intended if the redists are installed properly.
