以前在研究半透明不规则窗口的时候,用的是gdi的TextOut/DrawText绘制字体,但绘制出的字体是透明的,现在我完全放弃了GDI的TextOut()、BitBlt()的方式,而用SetDIBitsToDevice()代替,就是直接贴像素到DC里。
今天尝试用SetDIBitsToDevice()+UpdateLayeredWindow()实现半透明不规则窗口,结果非常顺利!贴出来,共享给需要的朋友.另外,本程序还附带了一个使用MMX汇编优化的32位alpha混合函数(57行,有详尽注释),需要的朋友可以直接copy了。
PS:关于字体的绘制我建议大家用GetGlyphOutline()手动提取字形像素去绘制,因为TextOut这类绘制函数功能有限,只适合初级软件使用,而要想画出丰富多彩的界面,比如字体alpha渐变,就必须自己操作像素,所以GetGlyphOutline()才是专业级的,而且兼容性好,可以抽象出来提供给ddraw、d3d、opengl等使用

在linux中实现一个命令执行程序doit,它执行命令行参数中的命令,之后统计1)命令执行占用的CPU时间(包括用户态和系统态时间,以毫秒为单位),2)命令执行的时间,3)进程被抢占的次数,4)进程主动放弃CPU的次数,5)进程执行过程中发生缺页的次数

这个只是方便生成授权,只要填入各个程序的licensehash就能生成不通的应用程序的授权了,licensehash的外置,比原版的生成器方便使用,只要一个生成器就能给你所有的加密程序提供授权的生成了。

本文中的代码已经在文中全部出现过了,为什么还需要一个下载币呢,是因为我的下载币不够用了额,下载其他大神的代码,需要,所以请赞助一下吧。
当然你不想赞助的话,你可以在文章中一个一个的copy,绝对的一模一样,绝对的开源,赞助一个下载币吧(配合作者博客使用)

在日常工作中,钉钉打卡成了我生活中不可或缺的一部分。然而,有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚,我总是得牢记打开钉钉应用,点击"工作台",再找到"考勤打卡"进行签到。有时候因为工作忙碌,会忘记打卡,导致考勤异常,影响当月的工作评价。而且,由于我使用的是苹果手机,有时候系统更新后,钉钉的某些功能会出现异常,使得打卡变得更加麻烦。 另外,我的家人使用的是安卓手机,他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说,每次打卡都是一次挑战。他们总是担心自己会操作失误,导致打卡失败。 为了解决这些烦恼,我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习,我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
