64-bit

问题 I have some code that reads the registry and looks for a value in HKEY_LOCAL_MACHINE\Software\App\ but when running on 64-bit versions of Windows the value is under HKEY_LOCAL_MACHINE\Software\Wow6432Node\App\ . How should I best approach this? Do I need a 64-bit installer or should I rewrite my code to detect both places? 回答1: If you mark you C# program as x86 (and not Any CPU) then it will see HKEY_LOCAL_MACHINE\Software\Wow6432Node\App as HKEY_LOCAL_MACHINE\Software\App\ .

问题 I've installed Python 2.7 from the python-2.7.amd64.msi package from python.org. It installs and runs correctly, but seems to be in 32-bit mode, despite the fact that the installer was a 64 bit installer. Python 2.7 (r27:82525, Jul 4 2010, 07:43:08) [MSC v.1500 64 bit (AMD64)] on win32 Type "help", "copyright", "credits" or "license" for more information. >>> import sys, platform >>> platform.architecture() ('64bit', 'WindowsPE') >>> sys.maxint 2147483647 What can I do to install Python so

问题 Does anyone know IF , WHEN or HOW I can get Memcached running on a Windows 64bit environment? I'm setting up a new hosting solution and would much prefer to run a 64bit OS, and since it's an ASP.Net MVC solution with SQL Server DB, the OS is either going to be Windows Server 2003 or (hopefully!) 2008. I know that this could spill over into a debate regarding 32bit vs 64bit on servers, but let's just say that my preference is 64bit and that I have some very good reasons. So far, I've tried a

问题 Does anyone know how I would go about detected what bit version Windows is under Python. I need to know this as a way of using the right folder for Program Files. Many thanks 回答1: platform module -- Access to underlying platform’s identifying data >>> import platform >>> platform.architecture() ('32bit', 'WindowsPE') On 64-bit Windows, 32-bit Python returns: ('32bit', 'WindowsPE') And that means that this answer, even though it has been accepted, is incorrect. Please see some of the answers

问题 I'm working on an implementation of the memcache protocol which, at some points, uses 64 bits integer values. These values must be stored in "network byte order". I wish there was some uint64_t htonll(uint64_t value) function to do the change, but unfortunately, if it exist, I couldn't find it. So I have 1 or 2 questions: Is there any portable (Windows, Linux, AIX) standard function to do this ? If there is no such function, how would you implement it ? I have in mind a basic implementation

问题 I have a text file that ends with .vbs that I have written the following in: Set Conn = CreateObject("ADODB.Connection") Conn.Provider = "Microsoft.ACE.OLEDB.12.0" Conn.Properties("Data Source") = "C:\dummy.accdb" Conn.Properties("Jet OLEDB:Database Password") = "pass" Conn.Open Conn.Close Set Conn = Nothing When I execute this on a Windows 32-bit machine it runs and ends without any notion (expected). When I execute this on a Windows 64-bit machine it gets the error Provider cannot be found.

问题 Is it possible to develop using the Android SDK on a 64-bit linux machine. The available SDK downloads seem to be just for 32-bit versions of Linux. 回答1: Yes, it is. You need to install the ia32 libraries. Check out the Ubuntu Linux troubleshooting section. apt-get install ia32-libs apt-get install sun-java6-jdk 回答2: On (K)Ubuntu you need following 32-bit packages: sudo apt-get install libstdc++6:i386 libgcc1:i386 zlib1g:i386 libncurses5:i386 for running the emulator you need that additional

问题 I have to copy a psTool utility to System32 folder when my application runs. I am on 64 bit Windows 7 and whenever, I try to copy the exe to system32 bit folder through File.Copy , the exe always gets copied to SysWow64 instead. When I put a breakpoint on destFile, the path is shown as C:\Windows\System32 but the file does not go in there (goes to sysWow64). I have tried the Special Folder SystemX86 , but the file again goes to sysWOW64. string sourceFile = "C:\bin\Debug\somexe.exe" string
