32-bit Versus 64-bit

Though this question could be abstracted out to apply to more than just Visual Studio, I'm really only concerned with Visual Studio and hope I can get some insight on 32-bit applications versus 64-bit. I have a 64-bit machine running Windows 8.1, with
VS 2013 installed, downloaded from the microsoft online store. Originally my machine was a 32-bit machine, so I originally purchased the 32-bit version of VS. A few months ago my 8-year-old machine finally crapped out and I bought a new system (which is 64-bit).
Since I had originally purchased the 32-bit version of VS 2013, that was the one I had to download and install into the new machine. So my copy of Visual Studio is located within the Program Files(x86) folder. Is this assumption correct: any apps I create
with my 32-bit version of VS will run on 32 or 64 bit systems. If this is true, am I correct in assuming that installing the 32-bit version of Visual Studio is therefore the safest way to go, as you can target more machines? For example, when VS 2015 comes
out, I should install the 32-bit version if I want the apps to run on 32-bit machines as well as 64-bit? Thanks.

Visual Studio is always a 32bit application. With Visual Studio running on 64bit Windows, you can build and debug both 32bit and 64bit applications.

32 bits versus 64 bits

Hi,
We are still using Solaris 2.6, but already planing an upgrade to 9.
For now, what are de advantages of 64 bits over 32 bits?
Thanks
AMF

Hi
The System Administrators Guide and the man page on boot have some useful information.
You could also try the following the phrase "why 64bit is better" in your favourite search engine :0)

In need of greater clarity on RAM and 64 Bit versus 32 Bit Apps...

i have 13 GB of RAM in my MacPro, and i am running Leopard. i noted, however, that Adobe Photoshop only appears to recognize 3072 mb of RAM (3 Gb) as it is still a 32 bit program. 32 bit programs can still only recognize a max of 3 Gb of memory.
i read somewhere that while Photoshop does not recognize all the RAM, that performance is increased even so, if you have more than 3 Gb of RAM; which would make sense as you can allocate that much to Photoshop and still have left over RAM for your system and other apps.
When i noticed that Photoshop did not recognize all my RAM i was extremely disheartened. After all, i did splurge quite a bit on the RAM in hopes of dramatically increasing performance in Photoshop.
But, as i think about it more, while Photoshop can only see 3 Gb of RAM, having 13 GB means that i can run more RAM intensive programs and each program will have enough RAM available. But i wonder what that means in terms of keeping up with the processors?
i have been in the habit of closing most programs when working in a RAM intensive program such as Photoshop to improve performance. But, i am thinking that i no longer have to really worry about this?
i would appreciate a discussion of this to add some clarity to the 32 bit/64 bit issue and RAM allocation on the MacPro.

Hello Gene.
My understanding is quite the same, 32bit programs theoricaly can't allocate more than 4G of RAM, maybe the 3G that you are talking about are anoter level of limitation, or caused by some allocations mechanisms beyond my knowledge.
When using your computer, take a look at Activity Monitor, and see how much RAM is free. As long as you have enough RAM, there is no need to close applications, since the memory manager will not start swapping on disk. Well, that said, I think it may improbe performance to close application to avoid memory fragmentation, but the impact is not the same.
And you're right, it is useless to have that much RAM for a single processus, but since Mac OS X has a pretty good multitasking, you can run lot of processes, each one allowed to use 4G of RAM, so that you keep performances even with lots of big applications launched.
Now, be patient, and wait for a full 64bit version of Photoshop to really enjoy your RAM
P.S. Maybe some plugins can detach new processes and get their own allocation space for some heavy filter operation ? If someone know, please clarify, that would be interesting.

How to check for 12-bit versus 16-bit audio?

Several hours of my first digital recordings were done with 12-bit audio (factory default). Later I changed the camera's settings to 16-bit, but I'm not sure when I did that.
Is there a way to check the audio bit-rate of a clip if the camera doesn't display that information? I'd like to periodically check the imported clips to determine when I started recording with 16-bit audio, because at that point I'll need to change the Easy Setup settings in FCE.
Thanks.

Unfortunately not. FCE assumes you set the easy setup correctly and will capture the audio as if it's that sampling rate. It's unfortunate that some cameras don't display this. If you capture fairly short segments, around 10 minutes, you should be able to get away with it however, especially if you don't capture across a TC break.

64 bits or 32 bits

Good evening
On my desktop I have the two 64-bit versions and 32 bit Adobe Indesign, Photoshop, Illustrator.
Could you tell me the advantages and disadvantages between these two versions.
Thanking you
Ulysses

To give you the 10,000 ft view of the advantages and disadvantages of the 32-bit versus the 64-bit versions of these products …
The real difference between the 32-bit and 64-bit versions of these products is the ability to use much larger address spaces with the 64-bit version. Generally speaking, for most documents and images, you will absolutely not see any performance advantage with the 64-bit versions of the applications (and in fact, there could be a very minor but measurable performance degradation with 64-bit). The advantage of the 64-bit versions is that they can directly access orders of magnitude larger virtual memory space. Typical 32-bit applications can only access a 2 GB virtual memory space, regardless of how much physical memory you have installed on your computer. This may sound quite ample, but when you are dealing with very long and/or very graphically-rich InDesign documents, for example, that 2GB memory is chopped up into temporary document storage, screen buffers, placed imagery temporary storage, and work spaces for a myriad of internal functions including layout, color management, content placement, PDF (and DPS and other format) export, printing, etc. Prior to InDesign 9, it was not uncommon to need to regularly exit InDesign and restart the program to reclaim these workspaces to avoid out of memory messages – these were not messages about being out of physical memory, but rather virtual memory. With the new 64-bit version of InDesign, these issues are of the past. Illustrator documents may be complex, but with rare exception contain only one artboard and typically don't have the same virtual memory issues. On the other hand, if you are a user that runs Photoshop with large number of layered, large, high resolution images open, the additional address space of the 64-bit version may be necessary for you as well.
Disadvantages of 64-bit are relatively few. If you use plug-ins for which there are not yet or might never be 64-bit versions, you might be stuck using the 32-bit versions for the time being. An example of this under Windows would be availability of a TWAIN scanner plug-in for Photoshop 64-bit – it doesn't exist.
All this being said, unless you have plug-in compatiblity issues, the 64-bit versions of Illustrator, Photoshop, and InDesign are mature and very stable and thus recommended. (Personally, I've hidden the Windows Start Menu items for both 32-bit Illustrator and 32-bit InDesign and have suffered no problems.)
Be aware that going forward, the 32-bit versions of these applications will eventually be dropped.

Creation of Add-on package for 64 bit and 32 bit SAP Business One Client

Please help me creating package for 64 bit and 32 bit SAP Business One. If Add-on executable is compiled with x86 option then there is no issue of connecting Add-on with 32 bit SAP Business one and if Add-on executable is compiled with Any CPU option then there is no issue of connecting Add-on with 64 bit SAP Business one. Problems are mentioned as below
1. My Add-on uses MS ACCESS connection and the connection is read using Jet OLEDB 4.0 provider. It works fine for x86 compile mode but not when compile mode is Any CPU. I searched for the issue on Google and found a solution to change MS ACCESS connection provider to ACE.OLEDB.12.0 but again ACE provider is installed according to the Office version i.e. 32 bit or 64 bit office suite. If I install 32 bit ACE provider then Add-on executable compiled with x86 version is working fine but with Any CPU option throws error as provider is not registered on current machine.
2. Secodly, our license validation activex dll is build using vb 6.0 and therefore when Add-on executable is compiled using Any CPU option, Add-on EXE cannot read from license dll. Any suggestion, how the activeX dll can be compiled whose component can be created from for X86 compiled exe and any cpu compiled exe.
Please help because we are stuck in this issue and cannot move forward.
Thanks.

Hi Alejandro,
That is one solution but did your add on used ms access connection? if you used Jet oledb to connection string or ace oledb connection string? what if 32 bit office is installed and what if 64 office is installed? how did you found the office version in install script? after determining the office version how did you installed Microsoft redistributable for ace oledb (32 bit or 64 bi )?
I am sorry that I asked many questions but these are the problems where I am stuck with the addon installer?
Thanks

What is difference between 32 bit and 64 bit sql server memory management

What is difference between 32 bit and 64 bit sql server memory management
Thanks
Shashikala

This is the basic difference...check if helps:
A 32-bit CPU running 32-bit software (also known as the x86 platform) is so named because it is based on an architecture that can manipulate values that are up to 32 bits in length. This means that a 32-bit memory pointer can store a value between 0 and
4,294,967,295 to reference a memory address. This equates to a maximum addressable space of 4GB on 32-bit platforms
On the other hand 64-bit limit of 18,446,744,073,709,551,616, this number is so large that in memory/storage terminology it equates to 16 exabytes. You don’t come across that term very often, so to help understand the scale, here is the value converted to
more commonly used measurements: 16 exabytes = 16,777,216 petabytes (16 million PB)➤ 17,179,869,184 terabytes (17 billion TB)➤ 17,592,186,044,416 gigabytes (17 trillion GB)➤
As you can see, it is signiﬁcantly larger than the 4GB virtual address space usable in 32-bit systems; it’s so large in fact that any hardware capable of using it all is sadly restricted to the realm of science ﬁction. Because of this, processor manufacturers
decided to only implement a 44-bit address bus, which provides a virtual address space on 64-bit systems of 16TB. This was regarded as being more than enough address space for the foreseeable future and logically it’s split into an 8TB range for user mode
and 8TB for kernel mode. Each 64-bit process running on an x64 platform will be able to address up to 8TB of VAS.

How to use SET BIT and GET BIT in ABAP Programming

Hi,
Our team is currently working for an Upgrade project which is using a tool automatically upgrades when we supplly the code. fine, But now the requirement is , we need to write different test cases for the available key words in ABAP. Now we r looking for the usage of " BIT ", keyword. so , kindly provide any program or code using this key word.
Please find the description Provided and give some relative ABAP code to satisfy the given description.
The data object byte_string must be byte-type. The statement reads the bit at the bit position BITPOS of the variable byte_string and assigns its value to the variable val. A default mode can be specified if required *
Thanks & Regards,
P.N.Kumar.

What on earth are you testing? That ABAP still works? I think SAP might have run that through rigourous testing themselves.
If you want sample code, why not read the ABAP help, and work some out for yourself?

Office Standard 2013 Key Management Service host 32-bit or 64-bit version ?

Hello,
I have a 2012 DomainController serving as our KMS host.
I need to activate 2013 Lync 32-bit clients so I will have to install the office 2013 KMS host.
The KMS host download is available in both 32-bit and 64-bit.
Should I download the 64-bit version because the 2012 OS is 64 bit or will I download the 32-bit host since the Office version we use is 32-bit?
BR
Sverre Amundsen

Hi,
Based on my understanding, I suppose that you want to activate 32-bit version of Lync 2013. Is it right?
If so, you can only install 32-bit version of Office 2013 on your PC. The 32-bit and 64-bit versions of Microsoft Office programs don’t get along, so you can only have one type installed at a time. If you mix 32-bit and 64-bit version installed
on the same PC, you might see some errors.
Reference about why can’t I install both the 32-bit and 64-bit versions of Office 2013:

By the way, there is an article about choosing 32-bit or 64-bit version of Office.

Is there a way to determine if an application is 32-bit or 64-bit?

Is there a way to determine if an application is 32-bit or 64-bit? To be more specific, I want to be able to determine if a 32-bit application is being emulated under WOW64. I'm trying to use the Call Library Function and selecting IsWOW64Process from the Kernel32.dll, but I can't seem to get it to work. I think I may be setting it up wrong. I'm using a constructor node and invoke node for Process and after calling GetProcesses in the invoke node I'm sending that into a For Loop to inspect each process seperately. Inside the For Loop is where I'm trying to use the Call Library Function. From what I've read IsWOW64Process has a Handle as an input and a pointer to a boolean as an output. I may be incorrect in this as I've seen multiple varieties of this call on the internet. I've tried setting this up but I can't seem to get it to work. I'm looking for help on how to correctly use the Call Library Function or if anyone knows a better way to do this I'm open to suggestions. Thank you for any help.
Solved!

Hi klynn,
I've got a link you might want to check out to make sure that your call function is correct.

OWB 10g Release 2 from 32 bit to 64 bit on Linux

Hi guys,
I have a client who is planning to migrate their Linux server from 32 bit to 64 bit and migrate their Oracle database from 10.2.0.3 from 32 bit server to 10.2.0.3 from 64 bit server.
We have OWB 10g Release 2 (10.2.0.3) installed in the 32 bit server.
Our DBA is planning to move the entire database to the new server including the OWB repositories.
My question is,
Will the following work?
1. Install the OWB 10g Release 2 (10.2.0.3 or 10.2.0.4) 64 bit in the new 64 bit Linux 64 bit server
2. Remove all the OWB repository user schemas & roles from the database where OWB is installed
3. Install the OWB repository in the new 64 bit server
4. Import the .mdl backup of the project from existing OWB 32 bit to the new OWB 64 bit server
5. Configure the project with the new server
OR
Since our DBA is planning to move the entire database to the new server including the OWB repositories
1. Install the OWB 10g Release 2 (10.2.0.3) 64 bit in the new 64 bit Linux 64 bit server
Will I be able to access my repository that is migrated from the 32 bit server (avoiding the installation of OWB repository and importing the project and configuring the whole project in the new server) ?
Please someone shed some light on this. Your help is appreciated
Thanks in advance....

Does this mean, ... we have to install the OWB 64 bit and install a new repository in the 64 bit server?In my opinion you don't need to create new repository.
After migrating database to 64bit perform steps from Metalink note 434272.1 "How To Update Warehouse Builder 10.2 After A Database Cloning".
It is better to save the same path for new OWB 64bit software. If you install OWB into different path you need to update OWBRTPS table with new path to OWB software (look at metalink note 550271.1).

ITunes 64-bit runs 32-bit, Secure link to iTunes Store failed, and SyncMapiInterfaceHelper_x64 crashes every time I click 'Info' tab in an iDevice.

Hello everyone,
There are 3 issues I have, as it reads in the title.
1) I am running iTunes on a Win7 64-bit ThinkPad, and iTunes shows up as a 32-bit application in the Task Manager, always. I tried even the complete uninstalling (after removing Bonjour, Apple Mobile Service, deleting the folders, etc.) and yet, it shows up the same way.
2) When I run diagnostics, it says 'Secure link to iTunes Store failed'. I've tried many things from whatever I've read in the forums and nothing seems to be changing that.
3) Every time I click the 'Info' tab on any iDevice (I tried it with a 3GS and a iPod Touch), I get a 'SyncMapiInterfaceHelper_x64 has stopped working' message thrice. I don't know the significance of thrice but it just does come.
I hope someone helps.
Thanks!

That one's normal. On 64-bit systems, iTunes is a mix of 32-bit and 64-bit componentry. The itunes.exe is 32-bit.
Oh, okay. Thanks!
Could you walk us through what happens when you try to connect to the Store, please?
The issue is when I run diagnostics. I happened to run it last night while updating my 3GS to iOS 6, and there was a 3194, and a search to solve that, led me to running the diagnostic.
I was wondering how it affects me because I haven't faced any issue in downloading or browsing the AppStore. The transcript of the 'Run diagnostics', for networks is as below:

With a Sun JDK or JRE, you can use java -version:
$ java -version
java version "1.6.0"
Java(TM) SE Runtime Environment (build 1.6.0-b105)
Java HotSpot(TM) Server VM (build 1.6.0-b105, mixed mode)
... switch to the 64-bit JDK ...
$ java -version
