Have you had the exasperating experience of a laptop orPDA defi antly not responding to your commands? Youfrantically press key after key, but to no avail. As hopeturns to anger (but just before you throw the company’slaptop through the window) you slam your fi nger againstthe on/off power button. Ten seconds later, your laptopfi nally surrenders and the screen goes black in a highpitched whimper.

制作加密文本文件程序1.原理從源文本文件中按順序讀出每一個(gè)字符,然后把讀出的字符轉(zhuǎn)換為相應(yīng)的ASCII碼,將此ASCII碼加上整數(shù)密鑰Key,最后把所得結(jié)果再轉(zhuǎn)回相應(yīng)的字符并同時(shí)把它寫入到另外一個(gè)文件中,這就是加密過程。解密碼過程與加密過程剛好是相反的操作。2.界面設(shè)計(jì)新建一個(gè)工程,在Form1中添加一個(gè)Label,一個(gè)Edit和兩個(gè)Button,程序的界面設(shè)置與布局如圖所示。圖一 界面布局
