iis服务器架网页远程播放ppt swf等office文档
项目需求：
1.服务器控制屏幕播放ppt等文档
2.通过传参的形式来修改播放文件，一共5个屏幕
方案1：
通过网页传参实现播放ppt，结果发现虽然实现了播放但是实际是是本地播放ppt，代码如下
public partial class mingdao : System.Web.UI.Page
{
static bool closeflag = false;
protected void Page_Load(object sender, EventArgs e)
{
string pptFileName = null;
OperatePPT op = new OperatePPT();
//op.PPTOpen(@"D:\QQPCmgr\Desktop\ppt\a.ppx");
pptFileName = Request.QueryString["name"];
/*Begin: Adde by PN:错误提示*/
//if (!op.PPTAuto(@"D:\QQPCmgr\Desktop\ppt\" + pptFileName, 3))
//{
// //if(openflag)
// //{
// // openflag = false;
// //}
// //else
// //{
// // Response.Write(string.Format("<script>alert('没有找到{0}')</script>", pptFileName));
// //}
// if (openflag)
// {
// Response.Write(string.Format("<script>alert('没有找到{0}')</script>", pptFileName));
// }
// openflag = true;
//}
/*End: Adde by PN:错误提示*/
op.PPTAuto(@"c:\ppt\" + pptFileName, 3);
Response.Write(string.Format("<script>alert('没有找到{0}')</script>", pptFileName));
}
}

显然这个方案不能满足我的需求功能
方案2：
通过将ppt等文档全部转换成swf 格式文件，然后 服务器端架网站，客户端就可以通过网页播放 下载demo链接：
