原创 ssh-keygen的使用方法
关键是看有没有用 something 和 something.pub 来命名的一对文件，这个 something 通常就是 id_dsa 或 id_rsa。有 .pub 后缀的文件就是公钥，另一个文件则是密钥。假如没有这些文件，或者干脆连 .ssh 目录都没有，可以用 ssh-keygen 来创建。它先要求你确认保存公钥的位置（.ssh/id_rsa），然后它会让你重复一个

原创 QTP对象能识别，但回放的时候却不响应
今天遇到一个问题QTP可以识别所有的对象，但是回放的时候按钮就点不上了。后来发现鼠标必须指在距离控件有一点距离的地方才能识别，与正常我们想的鼠标要放到控件上才能识别这个控件不同。出现这种现象是因为，浏览器的Zoom跟录制时的Zoom不一致了，我修改为100%就解决了。所以，大家要注意在录制的时候就选择一个合适的Zoom，回放时也要使用这个Zoom。
