I'm running into a problem because my database has BIGINT data (64-bit integers) but the version of PHP I'm running is only 32-bit. So when I pull out value from a table I end up with a numeric string representing a 64-bit integer in base 10. What I would ideally like to do is use the 64-bit integer as a bitmask. So I need to go to ei...
We are having an issue with remote dedubbing using Microsoft Visual Studio 2008 on a 32 bit XP client machine and a 64 bit Windows Server 2008 Virtual Machine on Hyper-V. When we debug the web project locally we can correctly see the modules loaded in the modules window (Ctrl + Alt + U) with the relevant symbols. When we try and debug ...
hi, have no idea what didn't you understand here: http://stackoverflow.com/questions/1583124/what-is-the-origin-or-the-reason-or-silent-failures-closed but i'm sorry anyway. i'll try to explain it again. in a winforms app, in a form's Load event, add the following line: throw new Exception(); and run the application. it ran witho...
Hi all We are planning to upgrade our test server and to do so we were planning on buying a 64 bit machine from Dell running Windows 2008 x64 Web edition. However, for now we would like to continue to use 32 bit Coldfusion 8. Is there anything to stop us doing this, or do we have to move to 64 bit Coldfusion 8? Has anyone had any p...
I have a VC++ project (2005) that generates both 32-bit and 64-bit dlls. The 32-bit dll is 1044 KB whereas the 64-bit version is 1620 KB. I'm curious why the size is so large. Is it just because of the larger address size, or is there a compiler option that I'm missing? ...
Hello. I recently installed W7 pro 64bits on my laptop, and then VS2008 pro with x64 compatibility. If i build any project, will it be built with 32 or 64 bit compatibility natively? And then, is it possible to change from 32 to 64 (or from 64 to 32) ? 'Cause most of my clients only runs 32bits applications, but I'd also liked to kno...
I am trying to port 32bit code to 64bit linux machine. Are there any compiler flags for 64bit posrting warning on Linux. There are +w2 -m64 flags for SUN. Could anyone give me information for flags similar to this one? Thank you in advance, ...
What are the guidelines for porting a 32-bit program to a 64-bit version? ...
Hi All, I want to build 64bit libraries for some of my C++ components. Is it required to compile/link the libraries in OS running on physical machine directly? Or can i use a OS running as virtual machine in ESX server to build the libraries? Would i need to take care of anything if i am building in a virtual machine? Please advice I w...
It appears that specifying the KEY_WOW64_64KEY flag (reference) when accessing a registry key under 32-bit Windows XP has no effect - that is, no error is thrown, and the key is opened as if you hadn't had the flag set. I know Windows 2000 throws an error when it encounters this flag. I want to make sure my app is compatible with as ma...
Hi all, I've got a simple benchmarking function using the C clock() function. start[timerId]=clock(); clock_t end; float dif_sec; end=clock(); dif_sec=((float)end-start[timerId])/CLOCKS_PER_SEC; printf("%s: %f seconds\n", msg, dif_sec); It's running fine in 32 bits on Mac OS X, but when I compile in 64 bits, the results are all wrong...
Hi: This question is about 64-bit Java apps in general, although I came upon it because of working with Netbeans/Eclipse. I'm using a 64-bit processor with a 64-bit OS (Windows 7). I wanted to run Netbeans/Eclipse with more than 4GB of heap memory (i.e., using the Xmx flag), but I'm running into some confusion. There doesn't appear t...
Is there a simple preprocessor macro that is defined for a 64-bit build? I thought _WIN64 might have been it, but even when I build a 32-bit target, the parts enclosed in a #ifdef _WIN64 ... #endif are compiled in, and this is causing problems. It's Friday and I can't think straight, but I'm sure I'm overlooking something very simple her...
I've got a windows service compiled as AnyCPU. I'm trying to get it into our installer to distribute. However... I am unclear on the difference between the 32 bit and 64 bit versions of InstallUtil. Does anyone know what (if any) there are? On my 64 bit machine, I can run either the $(WinDir)\Microsoft.NET\Framework64\v2.0.50727 or...
How do we add two 64 bit numbers using 32 bit arithmetic?? ...
I need to run/develop a mono-based application on a new dedicated server, and the ISP I usually use only offers 64bit Linux (of which I'll take Ubuntu) Is there any problems running mono on this configuration? ...
I recently got my home PC upgraded to a quad-core CPU and 64-bit OS. I have some former experience with C/C++ and I'm really "itching" to try exercising some 64-bit CPU capabilities. What's a good "Hello World" type program that demonstrates 64-bit multi-core capabilities by doing some simple things that don't work well at all in 32-bit ...
I created a WPF project in VS2008 and compiled it with Any CPU, x64 and x86. Any CPU and x64 works, but compiling to x86 the application is hanging when running through VS2008 and crashing when running without debugging. Debugging it with WinDbg I can see a StackOverflowException and sometimes a MissingMethodException relating to WPF met...
I'm looking for a hash function that: Hashes textual strings well (e.g. few collisions) Is written in Java, and widely used Bonus: works on several fields (instead of me concatenating them and applying the hash on the concatenated string) Bonus: Has a 128-bit variant. Bonus: Not CPU intensive. ...
I'm trying to port a native ATL C++ in-proc COM server to 64 bit in Visual Studio 2008. I've opened the Configuration Manager, added "x64" platform. Now I have 6 configurations - 3 for Win32 that compile and link fine and 3 for x64 that compile fine, but make the linker emit the following error: \Debug64\Objects\common.obj : fatal error...
