【软件简介】：本软件集合文本编辑器，文字绘图器，网页制作及游戏功能于一身。使您只须用鼠标轻点，便可制作出漂亮的文字符号图画，然后直接制作成为精美的彩色网页。同时又可将其作为普通的文本编辑器，象记事本程序一样简单使用。两种模式（绘图/编辑）切换只须轻轻一点，或按F3。如果做的闷了，打开游戏功能：一条由文字组成的贪吃蛇！看你能得多少分！最新功能：将横看的文本一下转换成为竖看的文本，连标点都一起改掉哟，好好玩，绝对反转文本文件为止！
【软件限制】：免费赠送注册码
【作者声明】：初学Crack，只是感兴趣，没有其它目的。失误之处敬请诸位大侠赐教！
【破解工具】：TRW2000娃娃修改版、Ollydbg1.09、FI2.5、W32Dasm 10修改版

【过 程】：
draw_txt.exe无壳。Delphi 编写。
无出错提示。用TRW下万能断点。返回程序领空后用F12走过几个RET就能到达核心了。
