Office 转 PDF & PDF 转 SWF Windows版

当网站有Office文件对外进行展示时，我们经常是不希望用户进行下载，而是在线进行预览。

这个时候就有必要把Office文件进行转换成SWF文件在网页中显示了

但现在还没有Office文件直接转化成SWF文件的方法，所以现在用PDF进行中转

也就是Office =》 PDF =》 SWF

以下是相应的转化代码（Windows环境）：Linux版请点：Office 转 PDF & PDF 转 SWF Linux版

因为调用Office不一定100%成功，有时不成功会卡死不关线程，这里进行定时断开

        }
        ///<summary>
        /// 指定超时时间 异步执行某个方法
        ///</summary>
        ///<returns>执行 是否超时</returns>
        public bool DoWithTimeout(string source, string target, TimeSpan timeSpan)
        {
            if (this.Do == null)
            {
                return false;
            }
            this.mTimeoutObject.Reset();
            this.mBoTimeout = true; //标记
            this.Do.BeginInvoke(source, target, DoAsyncCallBack, null);

            }
            return this.mBoTimeout;
