64-bit

问题 The question is easy! How do you represent a 64 bit int in C#? 回答1: 64 bit int is long 回答2: System.Int64 is the .net type, in C# it's also called long 回答3: A signed 64 bit integer is long , an unsigned is ulong . The corresponding types in the framwwork are System.Int64 and System.UInt64 , respectively. Example: long bigNumber = 9223372036854775807; 回答4: By using the long data type, or ulong for unsigned.

问题 Using: Visual Studio 2012 Professional and Ultimate with all latest updates How do I properly specify the configuration and platform to properly build x86 and x64. Visual Studio, when you first create a Winforms application gives you two configurations, Debug and Release, with AnyCPU defined as the platform. If you just target one platform, then the answer is easy, you go to the Build | Configuration Manager and select one of the platforms and then go to the project properties' build page and

问题 I've built an .ipa file with following flags armv7 armv7s and arm64. Is there any way/ tool through which i can make sure the .ipa does have the 64-Bit support? How does apple find out during app submission if the app binary does have 64-Bit support. 回答1: One of the options is to use lipo -info %path-to-executable% make sure you are not using path to .app folder or .ipa archive. 回答2: I have created a script that takes .ipa file as an input and returns what architecture the app supports -

问题 did anyone ever try to publish a netservice via Bonjour on a x64 system? I tried several libraries like Mono.Zeroconf, Deusty (there's some x64-discussion in the comments) and Zeroconf.Codeplex. They're working perfectly as long as I build my application for platform target x86. All I want to do is to publish my service into a LAN on any Win7 machine (x86/x64). Every hint is highly appreciated! Best Regards, Waescher 来源： https://stackoverflow.com/questions/5890280/bonjour-zeroconf-in-net-on

问题 This happens when compiling for Any Cpu as well as compiling to x86. Sections of the GUI doesn't redraw unless it's resized, for instance if the main form is maximized some of the controls don't resize with it, and others have sections that don't redraw and displays the what was previously there. This works fine on 32-bit machines, both XP and Vista, but on 64-bit Vista (don't have x64 XP to test with) the redrawing just isn't working properly. Anyone have any ideas on where to start tracking

I am trying to learn up to date x86 assembly all from old 386 base instructions through all the sse additions up until now. I read some things like SSE5

问题 Is there any msscript control in 64 bit? I google a bit and all say no 64-bit yet The reason that I need 64bit msscript.ocx is that I want to compile delphi projects in 64-bit using XE3. It compiles OK in XE3 and I have obtained a 64-bit exe but when it executes to the following line, script := TScriptControl.Create(nil); It gives me a 'Class Not Registered' error. I only found msscript.ocx under C:\windows\SysWOW64 but there is no such file under System32 folder. I really want this to work

问题 I'm studying some security related things and right now I'm playing around with my own stack. What I'm doing should be very trivial, I'm not even trying to execute the stack, simply to show that I can get control over the instruction pointer on my 64-bit system. I have turned off all protection mechanisms I'm aware of just to be able to play with it (NX-bit, ASLR, also compiling with -fno-stack-protector -z execstack). I don't have that much experience with 64-bit assembly and after spending

问题 I want to encode a 64 bit relative jump to the address stored in %rax in x64 assembly. AFAIK, there is no opcode for this, so I calculate the corresponding absolute address for the relative address manually and then I do an absolute jump to the absolute address: # destination address, relative to end of jmp instruction, is stored in %rax 00007ffff7ff6020: 0x0000488d1505000000 lea 0x5(%rip),%rdx # load %rip+5 (rip + size of add and jmpq) into %rdx 00007ffff7ff6027: 0x0000000000004801d0 add

问题 Here is the problem I am working on The Problem: A high speed workstation has 64 bit words and 64 bit addresses with address resolution at the byte level. How many words can in be in the address space of the workstation? I defined the different terms in the problem Word Size - Processor natural unit of data. The word size determines the amount of information that can be processed in one go Byte Level Addressing - Hardware architectures that support accessing individual bytes within a word 64
