查找替换程序:
加入Edit m_Edit button
头部加入变量:
CFindReplaceDialog* dlg;//声明"查找/替换"对话框指针
int nindex; //存储查找字符串的起始位置
int rindex; //替换字符串的大小
BOOL degree;//判断是否为第一次替换的变量
BOOL find;//判断是否进行查找的变量
初始化加入:
CString str="";
str += "君不见黄河之水天上来,奔流到海不复回。\r\n";
str += "君不见高堂明镜悲白发,朝如青丝暮成雪。\r\n";
str += "人生得意须尽欢,莫使金樽空对月。\r\n";
str += "天生我材必有用,千金散尽还复来。\r\n";
str += "烹羊宰牛且为乐,会须一饮三百杯。\r\n";
str += "岑夫子,丹丘生,将进酒,杯莫停。\r\n";
str += "与君歌一曲,请君为我倾耳听。\r\n";
str += "钟鼓馔玉不足贵,但愿长醉不复醒。\r\n";
str += "古来圣贤皆寂寞,惟有饮者留其名。\r\n";
str += "陈王昔时宴平乐,斗酒十千恣欢谑。\r\n";
str += "主人何为言少钱,径须沽取对君酌。\r\n";
str += "五花马,千金裘,呼儿将出换美酒,与尔同销万古愁。";
