32bit-64bit

Ensure that ASP.NET 3.5 Framework is installed on Windows Server 2003 64-bit

I'm developing in 32-bit XP and deploying to a Win2k3 64-bit server set to run in 32-bit mode. How do I install 3.5 framework components on the Win2k3 server in this scenario? I see that there are new charting controls and an SP1 for ASP.NET 3.5 How do I get these on the server that is running in 32-bit mode in IIS? ...

Retrieving the COM class factory for component with CLSID {XXXX} failed due to the following error: 80040154.

I developed a Windows service using C#.NET to generate PDF report. To generate PDF file I am using a third party dll. The application is running in my Windows XP platform. When I deployed the service in Windows Server 2008 64 bit version, I got this error: Retrieving the COM class factory for component with CLSID {46521B1F-0A5B-...

Migration of Java App Oracle 9i R2 database from 32 bit Windows to 64 bit Linux

We will be migrating our Oracle 9i R2 database from 32 bit Windows to 64 bit Linux (maintaining same Oracle version). Our Java (jdk 1.5) apps running on Linux 32 bit use the jdbc thin client ojdbc to connect to the db. While we don't as yet anticipate any issues for the Java app's connectivity and operation, we are working on a risk ass...

How do I use a 32-bit ODBC driver on 64-bit Server 2008 when the installer doesn't create a standard DSN?

I ran into an issue with some third party software that we use to track software license usage in our computer labs. We recently migrated the app to 64-bit Server 2008 after receiving assurances from the company that it was compatible and running some preliminary tests that showed that the app worked in the 64-bit environment. Unfortun...

64-bit library limited to 4GB?

I'm using an image manipulation library that throws an exception when I attempt to load images > 4GB in size. It claims to be 64bit, but wouldn't a 64bit library allow loading images larger than that? I think they recompiled their C libraries using a 64 bit memory model/compiler but still used unsigned integers and failed upgrade to us...

How to develop to take advantage of 64 bit systems?

Is there any specific sectors of Software Engineer/Computer Science where there's a marked difference when developing for 64 bit systems? I've been coding for around 10 years now, and since the break of 64 bit systems, my code hasn't changed one bit. What applications that a single coder can code as a side project require you to use 64...

What are the lower level advantages and disadvantages of 64-bit/32-bit?

I'm sure we've all heard the terms 64bit and 32bit thrown around, but what do they actually mean? I'm pretty sure they have to do with the size of a memory address. On a 64bit machine, a reference to an object is 64 bits. But I want to dig a little deeper.... One often hears the phrase "64bit machine." What part of the computer is act...

Processor, OS : 32bit, 64 bit

I am new to programming and come from a non-CS background (no formal degree). I mostly program winforms using C#. I am confused about 32 bit and 64 bit.... I mean, have heard about 32 bit OS, 32 bit processor and based on which a program can have maximum memory. How it affects the speed of a program. There are lot more questions which k...

InputManager plug-ins in Snow Leopard (OS X 10.6)

I'm getting conflicting reports from various places. Engadget's review says InputManager plug-ins being completely ignored (and causing strange behaviour if the application is loaded in 32-bit mode), but this mailing list thread says they will work if the 32/64-bit compatibility is right. So I have two questions: Do we get to use Inpu...

Mac Pro 64-bit addressing kernel

I am wondering about an app I am developing and 64-bit addressing. I would like to use around 12 GB of 32 GB available on a Mac Pro. Here's the thing, the kernel is not 64-bit in Snow Leopard on my Mac Pro (efi 32-bit). I am wondering though if I will be able to address that much ram, >4GB per application, even if the kernel is only 3...

Multiplying two 32 bit numbers without using 64 bit int ...

We are doing some 32bit * 32bit multiplication using the following algorithm Let us we want to multiply a (32 bit) with b (32 bit), both signed, a = ah * 2^16 + al [ah - Higher 16 bits, al - Lower 16 bits] b = bh * 2^16 + bl [bh - Higher 16 bits, bl - Lower 16 bits] We are effectively doing Result = (al * bl) + (((ah * bl) + (al * b...

Proper way to make a fat binary prefer to be 32bit on 64bit OS X 10.6?

Suppose I ask the user "do you want to run in 32bit mode or 64bit mode" and they pick 32bit. How do I register this fact with the operating system? I've looked at the arch command, but I don't want to have to write a script that wraps the binary. I suspect there is a plist-y way to do this, but I can't find documentation (other than a...

MS Build & Cruise Control - replacing a reference in a project from a 32bit version to 64bit version

Hi Guys, I have a solution which contains a project with a reference to a library that creates PDF files. The PDF library has a 32 bit version and a 64 bit version. During development, the project references the 32 bit version. I am developing on a 32 bit machine. I have Cruise Control triggering a build every time I check something...

Case for Higher Level Language: 64 or 32-bit?

With OS X 10.5.7 coming out, there's been a lot of talk about apps that are 64-bit vs. apps that are 32-bit... manufacturers that will have to convert apps, manufacturers that will not be able to any soon due to a lack of resources (it's apparently a huge deal), etc. What the benefits of converting a certain app (like iTunes) would be, e...

printf with sizeof on 32 vs 64 platforms: how do I handle format code in platform independant manner?

Very easy question for you Gurus but I haven't found the answer yet with about a good amount of searching. I have some code that prints the amount of memory used by the program. The line is similar to this: printf("The about of RAM used is %u", anIntVariable*sizeof(double) ); where anIntVariable is an int variable for the number of e...

Mac OSX 10.6 compiler: a puzzling experience with 32 vs 64 bit.

I have trouble understanding the gcc compiler provided by OSX 10.6 snow leopard, mainly because of my lack of experience with 64 bits environments. $ cat >foo.c main() {} $ gcc foo.c -o foo $ file foo foo: Mach-O 64-bit executable x86_64 $ lipo -detailed_info foo input file foo is not a fat file Non-fat file: foo is architecture: x86_64...

Build 32-bit with 64-bit llvm-gcc

I have a 64-bit version of llvm-gcc, but I want to be able to build both 32-bit and 64-bit binaries. Is there a flag for this? I tried passing -m32 (which works on the regular gcc), but I get an error message like this: [jay@andesite]$ llvm-gcc -m32 test.c -o test Warning: Generation of 64-bit code for a 32-bit processor requested. Warn...

Determining 32 vs 64 bit in C++

I'm looking for a way to reliably determine whether C++ code is being compiled in 32 vs 64 bit. We've come up with what we think is a reasonable solution using macros, but was curious to know if people could think of cases where this might fail or if there is a better way to do this. Please note we are trying to do this in a cross-platfo...
