SYMPTOMS

When calling the NetSessionEnum() Win32 API function in an application compiled with _MBCS defined, the SESSION_INFO_XX structure fields are not filled in correctly.

CAUSE

The NetSessionEnum() Win32 API function always returns values in Unicode in the SESSION_INFO_XX structures. However, the definitions for these structures in %MSVCDir%\Include\LMSHARE.h are incorrect. For instance, SESSION_INFO_10 is defined incorrectly as:

typedef struct _SESSION_INFO_10 {
    LPTSTR    sesi10_cname;             // client name (no backslashes)
    LPTSTR    sesi10_username;
    DWORD     sesi10_time;
    DWORD     sesi10_idle_time;
} SESSION_INFO_10, *PSESSION_INFO_10, *LPSESSION_INFO_10;

Note that the string fields are defined as LPTSTR, when they should have been LPWSTR.

RESOLUTION

The Platform SDK version of LMSHARE.h has the SESSION_INFO_XX structures defined correctly. Compiling with the Platform SDK version of LMSHARE.h gives correct results. You can download the latest release of the Platform SDK from the following Microsoft Web site:
