Hello,
have a problem by a customer in the attached code by DllExecuteCall( 
SCDLLASKFLAG , FLAG_UNREAD ), get an error "dllExecuteCall Internal data 
structures corrupted". On my computer I have no problems.

regards
Rudolf

  if  DllExecuteCall( aSOCMapi[4] ) == 0
         if (nErr := DllExecuteCall(aSOCMapi[5])) != SUCCESS_SUCCESS
             NotifyError( nErr )
             return {}
         endif
     endif

     //BEGIN SEQUENCE

         //Open (i.e. initialize) Inbox folder, goto Top message

         if (nErr := DllExecuteCall( SCDLLINBOXGOTOP )) != SUCCESS_SUCCESS
             //break nErr
