long-integer

I try to get Windows window title names and pids through handles with long objects. My code works but there is something wrong with it. I get only 4 window titles when I should get 10 or more. Can anyone help and tell me how to fix this code? I think the problem is with how I convert long objects (I don't understand them too well, as well as ctypes in general). from __future__ import print_function from ctypes import * psapi = windll.psapi titles = [] # get window title from pid def gwtfp(): max_array = c_ulong * 4096 pProcessIds = max_array() pBytesReturned = c_ulong() psapi.EnumProcesses

I am creating my Scala bean which is a configuration to be loaded from a YML config. I want a long property to be null if not specified, but I'm facing below issue. Any idea why? startOffset: Integer = null scala> var endOffset: Long = null <console>:11: error: an expression of type Null is ineligible for implicit conversion var endOffset: Long = null ^` PS: Yes I can use Option[Long] but wanted clarity and is there anything wrong with this approach. Scala Long is literal date type like long in Java. Same is true for Int . But Integer is a Wrapper class i.e java.lang.Integer If you want

I know, how to convert a Timestamp to a long, with the getTime() method. Is there a method that convert a long to a TimeStamp ? The constructor is doing that: Timestamp(long time) See: Timestamp.Timestamp(long) : new Timestamp(someLong) Yes, there's a constructor for Timestamp that takes a long as a parameter. http://docs.oracle.com/javase/6/docs/api/java/sql/Timestamp.html#Timestamp(long) 来源： https://stackoverflow.com/questions/10590324/java-convert-long-to-timestamp

I would like to represent a value as a 64bit signed long , such that values larger than (2**63)-1 are represented as negative, however Python long has infinite precision. Is there a 'quick' way for me to achieve this? Stephan202 You could use ctypes.c_longlong : >>> from ctypes import c_longlong as ll >>> ll(2 ** 63 - 1) c_longlong(9223372036854775807L) >>> ll(2 ** 63) c_longlong(-9223372036854775808L) >>> ll(2 ** 63).value -9223372036854775808L This is really only an option if you know for sure that a signed long long will be 64 bits wide on the target machine(s). Edit: jorendorff's idea of

Up until now i've been using the C# "Guid = Guid.NewGuid();" method to generate a unique ID that can be stored as the ID field in some of my SQL Server database tables using Linq to SQL. I've been informed that for indexing reasons, using a GUID is a bad idea and that I should use an auto-incrementing Long instead. Will using a long speed up my database transactions? If so, how do I go about generating unique ID's that are of type Long? Regards, Both have pros and cons, it depends entirely on how you use them that matters. Right off the bat, if you need identifiers that can work across several
