如何通过�E�序屏蔽windows�_�滞键之热键

Thu, 04 Mar 2010 05:36:00 GMT

最�q�在游戏开发中遇到�q�样的需求：玩家需要不停的�q�击shift键�?br> 大家都知道，在windows下默认连击shift键到5�ơ会弹出�_�滞键设�|�的对话框，如下图所�C��?br>

在游戏中必须屏蔽windows对粘滞键热键的反应，否则游戏体验��会非常差。在�|�上查找一�D�|��间后发现�Q�关于如何通过�E�序屏蔽�_�滞键热键的中文资料非常��，大多数的�{�案都是打开“控制面板”�Q�然后找�?#8220;辅助功能选项”条目云云�Q�这昄��不是�E�序员所需要的解决手法�?br> �l�过多方查找�Q�问题最�l�得以解冟뀂下面列表代码，以飨未来者，�E�序VC6.0+XP�pȝ��下运行通过�?br>

    // activate or inactivate sticky keys hot key (pop up  a set up dialog after continually pressed shift 5 times)
    bool ActivateStickyHotkey(bool isActivate, bool* pIsPreviouslyActivate= NULL)
    {

        STICKYKEYS skf;
        const DWORD datasize            = sizeof(STICKYKEYS);
        skf.cbSize                        = datasize;
        if (!SystemParametersInfo(SPI_GETSTICKYKEYS, datasize, (LPVOID)&skf, 0))

            return false;
        }

        const bool isPreviouslyActivate    = (skf.dwFlags & SKF_HOTKEYACTIVE) != 0;

2009�q�终奖个�E�计��器 python

Thu, 11 Feb 2010 07:32:00 GMT

看看你的�q�终奖发的是否合理：

def getTaxRatio(taxSalary):

    ratiolist    =(
            (500,    0.05, 0),
            (2000,   0.10, 25),
            (5000,   0.15, 125),
            (20000,  0.20, 375),
            (40000,  0.25, 1375),
            (60000,  0.30, 3375),
            (80000,  0.35, 6375),
            (100000, 0.40, 10375),
            (9999999,0.45, 15375)
            )

    if taxSalary>= 0:
        for ratio in ratiolist:
            if taxSalary<= ratio[0]:
                return (ratio[1], ratio[2])
    return (0, 0)

def calcYearAwardTax(yearAward):

    monthAward            = yearAward / 12
    taxRatio, taxAdjust    = getTaxRatio(monthAward)

    tax                    = yearAward * taxRatio - taxAdjust
    resultAward            = yearAward - tax

    retcode                = (yearAward, resultAward, tax, taxRatio, taxAdjust)
    #print('yearAward= %d, resultAward= %f, tax= %f, taxRatio= %f, taxAdjust= %d'%retcode)
    return retcode

################################################################################

import sys
import os

argNum    = len(sys.argv)
if argNum == 1:
    scriptName    = os.path.basename(__file__)
    print('usage1:    %s awardUpperBound'%scriptName)
    print('usage2:    %s awardLowerBound awardUpperBound'%scriptName)
    sys.exit()

print('-----------------------------------------------------------------------')

awardLowerBound, awardUpperBound        = 0, 0
if argNum   == 2:
    awardUpperBound                        = int(sys.argv[1])
elif argNum == 3:
    awardLowerBound, awardUpperBound    = int(sys.argv[1]), int(sys.argv[2])

if awardLowerBound> awardUpperBound:
        swap(awardLowerBound, awardUpperBound)

perfectAward, perfectGain                = 0, 0

for award in range(awardLowerBound, awardUpperBound + 1):
    retcode        = calcYearAwardTax(award)
    if len(retcode) > 2:
        if retcode[1]> perfectGain:
            perfectAward    = retcode[0]
            perfectGain        = retcode[1]

        if award== awardUpperBound:
            print('upperBoundAward= %d,\tgain= %f,\ttax= %f'%(retcode[0], retcode[1], retcode[0] - retcode[1]))

print("perfectAward= %d,\tgain= %f,\ttax= %f"%(perfectAward, perfectGain, perfectAward - perfectGain))

保存成文�?awardTax.py 然后在命令行调用卛_��?br>比如你年�l�奖发了25000�Q�则�Q?br>
ok, 那么你亏了，你比�?4000的同志多交税3625-2375= 1250元，最�l�收益还比他��?1625-21375= 250元�?br>�q�个数值段最佳的�q�终奖数额�ؓ24000�Q�因此还是向老板甌��给你发点年�l�奖吧�?

目录文�g比较工具 python

用于目录文�g的比较，如果有文件的md5��g��一��P�� 则copy覆盖。由于写的很久匆忙，没有加注释，但好在代码很��，如下�Q?br>
