fileupload问题

Question

我在本机写的程序运行也好用, 但是放到服务器上却没响应了. 而且FileUpLoad控件变成了可编辑的请问谁遇到过这类问题? 
代码如下
protected void Button1_Click(object sender, EventArgs e)
    {
        Response.Write("11111111111111");
        string strSql, strBiaoTi, strXueFen, strShiJian, strJiangJieRen, strFujian;
        strBiaoTi = Tb_biaoti.Text.Trim();
        strXueFen = Tb_xuefen.Text.Trim();
        DateTime dt = DateTime.Now;
        strShiJian = dt.ToString("yyyy-MM-dd");
        strJiangJieRen = Tb_jiangjieren.Text.Trim();
        if (this.ful_Video.FileName != "")
        {
            Response.Write("222222222222222");
            strFujian = this.ful_Video.FileName;
            try
            {
                Response.Write("3333333333333333");
                string path = Server.MapPath("~\\Video\\");
                this.ful_Video.PostedFile.SaveAs(path + strFujian);            }
            catch (Exception ex)
            {
                Response.Write(ex);
                return;
            }
        }
        else
            return;
        if (DataInfo.CompareText(Tb_biaoti, 50) && DataInfo.CompareInt(Tb_xuefen) == "ok" && DataInfo.CompareText(Tb_jiangjieren, 50))
        {
            Response.Write("444444444444444444");
            strSql = @"insert into ReMenKeCheng (KeChengBiaoTi,KeChengXueFen,JiangJieRen,ShiJian,FuJian) values('" + strBiaoTi + "'," + strXueFen + ",'" + strJiangJieRen + "','" + strShiJian + "','" + strFujian + "') ";
            DataBase Rs = new DataBase();
            bool bInfo = Rs.InsertDataRes(strSql);
            if (bInfo)
            {
                Response.Write("<script> alert('添加信息成功!') </script>");
            }
            else
            {
                Response.Write("<script> alert('添加信息失败!') </script>");
            }
            Bind();
        }
        else
        {
            Response.Write("<script> alert('请正确输入信息：课程标题和讲解人名字应该小于25个汉字或者50个英文字母，学分应该小于100并且都不能为空') </script>");
        }
    }

Answer 1

1、你查看一下读写权限有没有问题
2、文件保存路径是不是在你的网站的路径内，如你的网站是放到c:\iis\a下，而你文件保存路径指向c:\a，那保存不了也很正常
3、文件大小超过限制4M或者服务器上有没有你要上传的文件夹

这个代码 是我另一个工程代码, 但是这个却可以上传文件  这也没什么区别啊 ? 高手来帮帮忙吧!!!
