将水晶报告导出为特定文件夹中的pdf格式。 [英] Export crystal report to pdf format in the particular folder.

问题描述

亲爱的所有



我想将水晶报告导出为pdf格式。

以下代码有效。

唯一的问题是如何指定保存文件的文件夹。

< pre lang =c＃> protected void Button1_Click（ object sender，EventArgs e）
{
test.Load（Server.MapPath（ tiredata.rpt））;

mydbconn mycon = new mydbconn（）;
mycon.DBCreate（）;
DataSet3 dsobj = new DataSet3（）;

string query = SELECT serialno FROM TIM_TIRE_SIZE;

OracleDataAdapter myOracleDataAdapter1 = new OracleDataAdapter（query，mycon.conn）;

myOracleDataAdapter1.Fill（dsobj， tbl3）;

test.SetDataSource（dsobj）;

CrystalReportViewer1.ReportSource = test;

CrystalReportViewer1.DataBind（）;
oStream =（MemoryStream）

test.ExportToStream（ExportFormatType.PortableDocFormat）;

Response.Clear（）;

Response.Buffer = true ;

Response.ContentType = application / pdf;

Response.BinaryWrite（oStream.ToArray（））;

ExportFormatType formatType = ExportFormatType.NoFormat;
formatType = ExportFormatType.PortableDocFormat;

test.ExportToHttpResponse（formatType，Response， true ， 吉瑞）;

Response.End（）;

oStream.Close（）;
mycon.DBclose（）;

ClientScript.RegisterStartupScript（GetType（）， 消息， < SCRIPT LANGUAGE ='javascript'> alert（'ok'）;< / script> ）;
}

解决方案

你不能。在服务器上运行的代码无法控制客户端保存文件的位置 - 甚至是什么。



在你问之前，不，没有解决方法。如果有，那将是一个主要的安全漏洞。

Dear All

I want to export crystal report to pdf format.
Following code works.
Only thing is how can I specify the folder to save the file.

protected void Button1_Click(object sender, EventArgs e)
{
    test.Load(Server.MapPath("tiredata.rpt"));

    mydbconn mycon = new mydbconn();
    mycon.DBCreate();
    DataSet3 dsobj = new DataSet3();
    
    string query = "SELECT serialno FROM  TIM_TIRE_SIZE ";
    
    OracleDataAdapter myOracleDataAdapter1 = new OracleDataAdapter(query, mycon.conn);

    myOracleDataAdapter1.Fill(dsobj, "tbl3");

    test.SetDataSource(dsobj);

    CrystalReportViewer1.ReportSource = test;

    CrystalReportViewer1.DataBind();
    oStream = (MemoryStream)

    test.ExportToStream(ExportFormatType.PortableDocFormat);

    Response.Clear();

    Response.Buffer = true;

    Response.ContentType = "application/pdf";

    Response.BinaryWrite(oStream.ToArray());

ExportFormatType formatType = ExportFormatType.NoFormat;  
    formatType = ExportFormatType.PortableDocFormat; 
   
    test.ExportToHttpResponse(formatType, Response, true, "giri");

    Response.End();

    oStream.Close();
    mycon.DBclose();      
    
    ClientScript.RegisterStartupScript(GetType(), "Message", "<SCRIPT LANGUAGE='javascript'>alert('ok');</script>");
}

解决方案

You can't. Code running on the server has no control over where - or even if - the client saves a file.

And before you ask, no, there is no workaround. If there was, it would be a major security vulnerability.
