VB程序密码忘记了怎么破解？
用下面这个软件，暴力破解只需几秒钟，无论多么复杂的密码
Advanced Office Password Recovery
怎么破解vb6.0版 我只下了个安装包 但是要钱
C:\Program
Files\Microsoft
Visual
Studio\VB98
然后再重新安装....
可新建类型
那些
其实是放在
C:\Program
Files\Microsoft
Visual
Studio\VB98\Template
目录下的
Project
目录下的文件....
如果还是没有,
可以看看光盘
\VB98\TEMPLATE\
下的目录下是否有文件....
