Problem Using the ProjectWise SDK with VBA in Microsoft Access

When I want to connect to PW in Access with aaApi_LoginDlg (0, 0, 0, 0, 0, 0), no Datasource is displayed.

Identical VBA code works perfectly with Excel. it's amazing that this external dll doesn't work the same with Excel and Access.

My IT thinks it's because the SDK doesn't know where the data source server is, but it doesn't have the solution.
