Web程序中将Cell华表的修改 保存到数据库或服务器端文件夹内

1.JS端 调用UploadFile方法

2.处理页面的相关编码

=========================

1.

----------------

//JS端 调用UploadFile方法

//该方法可能部分低版本不支持

var flag1 = cellShow.UploadFile("ReportUpload.aspx?

ReportType=1&CellType=1&CellTitle="+escape(FiledTitle)+

"&CellModule="+escape(cellModule)+"");

2.

----------------

//ReportUpload.aspx页面的相关代码

//该页面为空页面

//只需要Page_Load内如下相关操作就可

using ...

using System.IO;

protected void Page_Load(object sender, System.EventArgs e)

{

// 接收客户发来的文件流

int nBytes = Request.TotalBytes;

byte[] UpFile = new byte[nBytes];

UpFile = Request.BinaryRead(nBytes);

// 保存到CellReport数据库中

string myConnString = "Provider=Microsoft.Jet.OLEDB.4.0;data source =";

OleDbConnection myConn =

new OleDbConnection( myConnString + Server.MapPath("CellReport.mdb"));

myConn.Open();

string sql = "SELECT * FROM CellReportUpload";

OleDbDataAdapter myAdapter = new OleDbDataAdapter(sql, myConn);

OleDbCommandBuilder oleDbCommandBuilder = new OleDbCommandBuilder(myAdapter);

DataSet ds = new DataSet();

myAdapter.Fill(ds, "CellReportUpload");

DataRow dr = ds.Tables["CellReportUpload"].NewRow();

dr[1] = UpFile;

ds.Tables["CellReportUpload"].Rows.Add(dr);

myAdapter.Update(ds, "CellReportUpload");

ds.Tables["CellReportUpload"].AcceptChanges();

myConn.Close();

// 保存到磁盘文件,通过流将数据保存成文件

string strCellTitle = Request.QueryString["CellTitle"];

string strCellModule = Request.QueryString["CellModule"];

string strCellPath = "rpt" + strCellModule + "/where_" + strCellTitle + ".cll";

if (File.Exists(Server.MapPath(strCellPath)))

File.Delete(Server.MapPath(strCellPath));

Stream fStream = new FileStream(Server.MapPath(strCellPath), FileMode.Create);

fStream.Write(UpFile, 0, nBytes);

fStream.Close();

}
