32bit-64bit

问题 The Windows operating system can be either 32 bit or 64 bit. The 64 bit version is called Windows x64 but the 32 bit version is called Windows x86 . Why isn't it called Windows x32 ? What is the reason? 回答1: x86 is the name of the architecture that it's built to run on (the name comes from a series of old Intel processors, the names of which all ended in 86, The first of which was the 8086). Although x86 was originally a 16-bit architecture, the version in use today is the 32-bit extension.

问题 Hello again community, I'm looking for a solution to 32 bit .mdb's conflicting with my 64 bit environment: 64 bit Windows 7, with a 64 bit MS Access Database driver running 64 bit python. I want to write data from these .mdb's into a 64 bit PostgreSQL database and possibly also to .csv files. However, I would like this tool to not only work on my machine but also those of colleagues so it would ideally be able to handle other environments as well. Initially I had a script writing to .csv with

问题 I'm writing software in Python3 (more specifically: Python 3.8.1 ). At some point, the software needs to check if some arbitrary executable is 64-bit or 32-bit. After some research, I found the following post: Checking if an exe is 32 bit or 64 bit In this post, the following solution is offered: subprocess.call(['dumpbin', '/HEADERS', 'test2.exe', '|', 'find', '"machine"']) Unfortunately, this doesn't work in Python 3.8.1 . That post is almost 8 years old and dates back to the Python 2.x

问题 I have created an x86 "wrapper" for an x86 library we have from a vendor. I've been following the steps mostly from this post as well a couple links for calling COM here and here. I marked the project as "Register for COM interop". I was able to find by COM interface using oleview and marked it as "Use Surrogate Process". So hopefully I'm good to this point as far as the DllSurrogate registry settings go. Now I can't seem to get the reference correct to consume the x86 COM. Supposedly I can

问题 Given a Windows process handle, how can I determine, using C++ code, whether the process is 32 bit or 64 bit? 回答1: If you have handle to the module then you can do this: IMAGE_NT_HEADERS * headers = ImageNtHeader(handle); if ( headers->FileHeader.Machine == IMAGE_FILE_MACHINE_I386 ) { //module is x86 } else if ( headers->FileHeader.Machine == IMAGE_FILE_MACHINE_AMD64 ) { //module is x64 } I took help from my own answer. 回答2: If you have a process handle, use IsWow64Process(). If
