(4)如果检测到文档被篡改，软件会对文章内容画红线并且弹出提示框提示用户，如图3.5所示。
 
if (1!=wrongflag) {MessageBox("水印错误，文档已被篡改");}
fontwrong.ReleaseDispatch();
font.ReleaseDispatch();
sel.ReleaseDispatch();

4.1    水印嵌入测试
用户打开要嵌入的WORD文档后可以输入任意1-99范围内的密钥，然后生成对应水印如图4.1所示。 基于WORD文档的防篡改水印系统设计与实现(13):http://www.youerw.com/jisuanji/lunwen_1627.html
