求助： 验证码字库

杨子520 发布于 2008-11-06 16:27， 4383 次点击
诚恳求助如图所示的验证码字库！
在一个为孩子的投票网站，大家都在作弊，所以本人也想尝试，可是这个样子的字库在网络上没找到，哪位大师能帮忙做一个！

类似与这样的图片，字库文件的扩展名为 .dat
附一个经压缩过的.dat文件！

那不是字库，那是程序生成的文字图片，不是调用的图片文件，明白不

谢谢楼上的两位斑斑，偶太笨，电脑里也没装类似这样的软件，即使装也不会用，所以不太明白那些代码怎么能生成文件（扩展名是.dat)，能不能生成一个文件给我？？
再一次谢谢你们的热情！！！

你是要作弊还是要防止别人作弊？

杨子5202008-11-11 16:09
当然是我在作弊，很不好意思说这样的话，不过，大家都在做，所以说这个脸也就不红了！
嘿嘿！继续期待高人给个文件！

你要作弊应该找软件去啊，怎么跑我们asp论坛来了，asp是脚本程序，不是应用程序

软件已经找到了，就差一个字库文件，应用的就是asp技术~

你要的字库文件就是楼上的楼上的楼上提供的代码，那就是验证码生成代码，但你的软件不支持这种方式的字库，你只有去不停的刷新把每次不同的单个字截图下来自己去建立字库
