msvcrt

My code is below: import msvcrt while True: if msvcrt.getch() == 'q': print "Q was pressed" elif msvcrt.getch() == 'x': sys.exit() else: print "Key Pressed:" + str(msvcrt.getch() This code is based on this question ; I was using it to acquaint myself with getch . I've noticed that it takes 3 pressing the key 3 times to output the text once. Why is this? I'm trying to use it as an event loop, and that's too much of a lag... Even if I type 3 different keys, it only outputs the 3rd keypress. How can I force it to go faster? Is there a better way to achieve what I'm trying to achieve? Thanks!

A C++ program that uses several DLLs and QT should be equipped with a malloc replacement (like tcmalloc ) for performance problems that can be verified to be caused by Windows malloc. With linux, there is no problem, but with windows, there are several approaches, and I find none of them appealing: 1. Put new malloc in lib and make sure to link it first (Other SO-question) This has the disadvantage, that for example strdup will still use the old malloc and a free may crash the program . 2. Remove malloc from the static libcrt library with lib.exe (Chrome) This is tested/used(?) for chrome

The fopen function returns a pointer to a FILE structure, which should be considered an opaque value, without dealing with its content or meaning. On Windows, the C runtime is a wrapper of the Windows API, and the fopen function relies on the CreateFile function. The CreateFile function returns a HANDLE , which is used by other Windows API. Now, I need to use Windows API deep inside of a library that uses fopen and FILE* . So: is there a way to get the HANDLE from the FILE structure? As this is compiler specific, I mean on the MSVC runtime library. I understand that this would be an ugly, non

I know this has been asked in other places and answered, but I'm having issues with MS Visual Studio 2010. I've developed a C++ executable but if I run the Release version on a machine that doesn't have the VC++ runtime library (ie, msvcr100d.dll), I get the "program cannot start because msvcr100d.dll is missing from your computer" error. This is weird for two reasons: Why is it trying to link with the debug version of the redistributable? I tried applying this fix , setting the runtime library setting to /MT instead of /MD (multi-threaded DLL), but that only made the problem worse (if I

Compiled couple of .dll's using visual studio 2015, and tried to deploy on some older windows 7 / 64 bit. Tried also to guess which dll's are needed for application to start and copied MSVCP140.DLL & VCRUNTIME140.DLL - but application could not load vs2015 dll. Started to analyze what is wrong - and dependency walker showed dependencies from following dll's: API-MS-WIN-CRT-MATH-L1-1-0.DLL API-MS-WIN-CRT-HEAP-L1-1-0.DLL API-MS-WIN-CRT-CONVERT-L1-1-0.DLL API-MS-WIN-CRT-STRING-L1-1-0.DLL API-MS-WIN-CRT-STDIO-L1-1-0.DLL API-MS-WIN-CRT-RUNTIME-L1-1-0.DLL API-MS-WIN-CRT-FILESYSTEM-L1-1-0.DLL API-MS

I am using VS2008 for developing a COM dll which by default uses CRT version 9 but I am using TSF (Text service framework) that is not compatible with the new CRT. I think the solution is to use the compatible one so how can I specify the CRT version? I whole heartily join the recommendation not to manually change the CRT version you link against. If however, for some reason (which I cannot imagine) this is the right course of action for you, the way to do so is change the manifest for your project. First make sure a manifest is not generated on every build (on VS2005: Configuration properties
