Using Visual Studio 2005, I wrote a simple DLL in C that uses the Windows API to send UDP datagrams and that is hooked into a third-party program. On a 64 bit machine, it does not work at all, as the third-party code was compiled for 64 bit in this case. So I need to ship two versions of the same DLL - one for 32 bit, one for 64 bit. Ho...
Let's say I'm programming in Java or Python or C++ for a simple problem, could be to build an TCP/UDP echo server or computation of factorial. Do I've to bother about the architecture details, i.e., if it is 32 or 64-bit? IMHO, unless I'm programming something to do with fairly low-level stuff then I don't have to bother if its 32 or 64...
I have some crashes in some C code, built without debugging symbols, and I have only a backtrace with the absolute addresses of the call stack. This is on windows (64 bits). I am more of a linux guy, so I am a bit lost at how to look into debugging this - on Linux, I would run the code under valgrind, but AFAIK, no such tool exists for w...
Generally speaking, Will a .net winforms application work in a 64-bit OS or does it need to be modified? ...
I installed psqlODBC and when I go to Control Panel -> Data Sources (ODBC) I don't see the Postgres driver installed. I rebooted, still nothing. I then noticed that if I launch this control panel applet from the file c:\WINDOWS\system32\odbccp32.cpl the drivers suddenly appear! This happens on an XP 64 bit machine. I can't really ex...
Well, okay. There's Visual Studio 2008 and Embarcadero Delphi/Studio that are both able to create 64-bits .NET applications for Vista. And of course a lot of 32-bits applications will run on 64-bits Vista. If not, it's always possible to install VMWare to create a virtual 32-bits Windows XP system to run 32-bits applications. So, plenty ...
A Java app running under JBoss (using 64 bit JRockit) needs to communicate with a third-party 32 bit C++ dll (doing calls to an external service). Are there more clever ways to solve this than putting a .NET web service between the two? ...
I have a rather memory hungry java application. On my 32 bit systems with Windows XP Professional the application will just run fine if I give it -Xmx1280m. Everything below will end up in an java.lang.OutOfMemoryError: Java heap space exception. If I run the same application on a 64 bit Windows XP Professional (everything else exactly ...
Does a application in .NET need to be built in 64 bit to take full advantage of a machine with a 64 bit OS on it, or will it take advantage of it just as a 32 bit build. Basically, we have an issue with an out of memory exception and it was suggested to run the console app on a 64 bit box which "may" solve the issue. The question is can ...
Hi guys, I've got a little game that a friend and I are writing in Java. It's kind of badly coded and we're working on refactoring it, but that's not really the issue right now. We both have 64 bit machines and I guess before we were both using 32 bit JDKs, but recently I had some problems and so I removed all JDKs and installed the lat...
When I use the Web Platform installer on Vista x64 Business it doesn't list any of the applications (such as DotNetNuke or SubText). Has anyone got it to work on Vista 64? ...
I'm using MSBuild (via NAnt) to compile a bunch of VB.Net assemblies. Because these assemblies depend on COM Interop, I need to guarantee that they run in 32 bit mode on 64 bit OS's. I can get the executable assemblies to compile to 32 bit by changing the project in Visual Studio, but I'd really like to be able to force all of the exec...
Is there a way to execute a .net application compiled under AnyCPU as a 32-bit application when running in a 64-bit Windows environment without recompiling as x86? ...
I'm porting my application from 32 bit to 64 bit. Currently, the code compiles under both architectures, but the results are different. For various reasons, I'm using floats instead of doubles. I assume that there is some implicit upconverting from float to double happening on one machine and not the other. Is there a way to control ...
I've been given a windows service which references a COM component that only runs on 32-bit. My machine is x64, so the service tries to start, fails to create the COM component, and dies. I don't have the source, just the .exe file. Is there any way to force a service to start in 32-bit mode on a win64 machine? ...
I am beginning to port a program which is written in C and have several pieces of code written in assembly with instructions for a 32 bit machine - like ljmp - to a 64 bits machine. Is there a place/document that have the instructions, in assembly, for a 32 bit machine and its counterpart for a 64 one? If not, where can I find a documen...
I'm developing SharePoint solutions on a virtual 32bit machine, and I use Wix to package the setup. I'm targeting both 32bit and 64bit environments with my solutions, but in order to create 64bit MSI's, I need to have have a 64bit machine and the 64bit version of WiX. Normally, this wouldn't be an issue, since I would have just simply ...
I am having problem with the contents of a pointer passed as the wParam from a 32-bit C# application is changing along the way to a 64-bit C++ process. There are two processes 32.exe (in C#) and 64.exe (in C++). 64.exe is started as a child process of 32.exe. 32.exe post window message for 64.exe, one of which has a wParam that is a poi...
My MSI installer created with Visual Studio 2008 refuses to install the app in the designated directory and instead will only install the app in the root directory. If I take the same MSI and install in on an x86 system the installer installs the app in the directory specified. I am developing the app and MSI on Server 2008 and Win7 RC...
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...
