32bit-64bit

问题 I am using a WebFrame to load a request to a website that is running Microsoft SilverLight. When I build my application using the 64-bit Intel architecture (x86_64), it runs fine. However, because I must use a third party library built for 32-bit Intel, I must build my application using that architecture. When I do that, I get the following error message <Error>: clip: empty path. prior to a second call to - (void) webView:(WebView *)sender didFinishLoadForFrame:(WebFrame *)frame and my

问题 I'm having issue running my application locally because of the bitness problem. However, if I deploy it to the server and set the application pool 64bit then it works fine. I need this to work local so I can debug the project. I'm hoping someone could help me. These are the things I have checked so far: use corflag to make sure the dll is in 64bit make sure the prefer 32bit is not checked make sure the target platform is set to 64 bit in my main project and the dependent project I'm running

问题 I want to be able to predict the default install location of an application. On a 64-bit machine, if it is a 32-bit application, it would install in "Program Files (x86)" and if it were a 64-bit application, it would install in "Program Files". My goal is to install the application with its default location and validate if the install was fine. But for this I need to know where it would be installed. If I know what architecture the application is built for, I think it would serve my purpose.

问题 Background: I want to store numbers that are precise to 4 decimal places, without roundoff. So I thought of using integers internally; for example, 12.3456 is represented as 123456 internally. But with 32b integers, I can count only upto 214748 , which is very small. I guess that 64-bit integers are the solution. But are operations involving 64-bit integers less efficient than 32-bit integers, given a machine running a 64-bit JVM? BTW, I am using an information retrieval package (Solr), an

问题 How fortunate it is for all of use learning the art of computer programming to have access to a community such as Stack Overflow! I have made the decision to take up the task of learning how to program computers and I am doing so by the knowledge of an e-book called 'Programming From the Ground Up', which teaches the reader how to create programs in the assembly language within the GNU/Linux environment. My progress in the book has come to the point of creating a program which computes the

问题 I have some inherited code for FlexLM that is converting an integer to a pointer that needs to work on both 32bit and 64bit machines. The integer is being filled in from argc of the arguments to the program using scanf to read the integer value. How should I reliably read the argc string to get a value suitable for assigning to a pointer so that it works on both 32bit and 64bit machines? Presently the code looks something like this: // FlexLM includes this: typedef char * LM_A_VAL_TYPE; /* so

问题 I have several C# Windows service. One insists on running as a 64 bit process. This wouldn't be a problem except that I migrated all shared configuration, to C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config As a result the service fails to read the config, and for the moment I am having to duplicate the shared configuration (which defeats the point of moving it to machine.config) I have changed the build configuration from x64 to x86, and re-installed but the service still runs in 64 bit

问题 I cannot install gmpy (1 or 2) on OS X Mountain Lion without warnings. I tried pip , I tried compiling, I installed gcc 4.2.1 and tried to compile gmp with i386 arch (though my Mac is 64bit), none of them are working! The thing is I can setup gmpy with Python 3+ without warnings but not with Python 2.7. The verbose I get when I use: python setup.py install for gmpy2 is: running install running build running build_ext building 'gmpy2' extension creating build/temp.macosx-10.6-intel-2.7

问题 I have a stable 32bit eclipse installation on my 64bit windows7 for android programming. In parallel I am developing a simple java program ( non android, no jni's ) within the same eclipse ( 32bit ) that I should run in a 64 bit jvm ( needs more heap space ). Is that possible ? ( I am asking, because I do not want to destroy my stable development environment by experimenting of installing 64bit and 32bit jvm in parallel ) The question in other words: Is it possible to run/launch ( green play

问题 I am trying to execute a JNI call on a 64 bit linux machine but the library is only supported on a 32 bit machine. Can I force my 64 bit linux to use a 32 bit jvm? when I type java -d32 version, I get the message "Running a 32 bit jvm is not supported this platform". I would like to know how to install a 32 bit jvm on the 64 bit machine so I can get my native library to work 回答1: It appears that you cannot typically have both 64 bit and 32 bit JDK on the same Linux system (according to Oracle
