这个为啥呢,只好把截图的函数代码翻出来看,以前是用这种方式的:BitBlt(dcImage,0,0,(int)(rect.Width),(int)(rect.Height),dcScreen,(int)(rect.Left),(int)(rect.Top),TernaryRasterOperations.SRCCOPY);
凭直觉感觉应该是由于这种通过DC的方式对WPF程序支持有问题,但是又觉得奇怪就是截取其它的WPF组件和窗口都没有问题,偏偏Popup窗口不行。

随着不可再生资源的日益减少,人们对新型清洁能源的需求增加;
促进了诸如太阳能发电、风力发电、微电网行业的发展,在这些行业产品中需要能量的存储释放、能量的双向流动;
太阳能、风力发出的电需要升压逆变之后才能接入电网,而对于电池或者超级电容的充放电需要系统能够具备升压和降压的功能。
双向同步整流BUCK-BOOST变换器能够很好的满足需求,相对于单纯的BUCK电路或BOOST电路,不只能实现能量的双向流动,还能在同一方向实现升降压功能。
能够实现能量双向流动功能电路拓扑有很多种,同步BUCK电路可以是正向降压反向升压的双向DC-DC变换器,同步BOOST电路亦是如此;
双向DC-DC变换器一般可以通过用MOS管代替经典拓扑电路中整流二极管得到新的拓扑,例如双向Cuk电路、Sepic电路、Zeta电路等,本设计中采用同步BUCK电路和同步BOOST电路级联而成的同步整流BUCK-BOOST电路拓扑,该拓扑结构简单,易于控制。

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。
