In Microsoft Windows CE 5.0, an application may call the
SCardGetStatusChange API function. However, the
SCardGetStatusChange function does not report the
SCARD_STATE_INUSE status in the
dwCurrentState field of the
SCARD_READERSTATE structure for the smart card reader. This problem occurs most frequently when the following conditions are true:
- The application that calls the SCardGetStatusChange function is running on a Microsoft Windows Terminal Server session.
- The application queries a smart card reader that is attached to a Windows CE-based thin client.
This problem occurs because of a coding error in the Scard module. This coding error causes the reader state flags to be read from the wrong location.
