xpdf
public OpenFileDialog ofdlg = new OpenFileDialog();//打开文件对话框
public string filename;
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
ofdlg.Filter = "pdf文件(*.pdf)|*.pdf";//选择pdf文件
if (ofdlg.ShowDialog() == DialogResult.OK)
{
filename = string.Format("{0}", ofdlg.FileName);
}
}
//传送打开文件对话框中得到的filename来做为外部程序的参数来做转化
private void button2_Click(object sender, EventArgs e)
{
Process p = new Process();
string path = "pdftotext.exe"; //进程启用外部程序
//这个exe我放在debug文件夹下面
p.StartInfo.FileName = path;
p.StartInfo.Arguments = string.Format( filename + " -");//很怪异的一行
//参数“－”表示可以得到输出流
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardInput = true;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.RedirectStandardError = true;
p.StartInfo.CreateNoWindow = true;
p.Start();
string s = p.StandardOutput.ReadToEnd();//得到pdf文档中的文本内容
textBox1.Text = s;
p.Close();
}
}
上面的程序运行后，如果是在Debug文件夹下的pdf文件就可以得到输出，可是如果在打开文件对话框中打开我桌面上的一个pdf如：@"d:\我的文档\test.pdf"，输出就会是空，但是如果把上面那怪异的一行改为：
C# code
p.StartInfo.Arguments = string.Format( @"d:\我的文档\test.pdf" + " -");
程序就又会得到输出。
呵呵，谢谢楼上的兄台，下载的xpdf中xpdftotext.exe用到的配置文件xpdfrc需要手动配置，我如果把那些字体啊，什么的映射成绝对路径下的文件，就不会出现上面的问题，但是我把配置文件中的路径改成了相对路径，于是就出现了上面的问题了，看兄台能够很轻易的就运行成功，一定是做过很多代码的，这里还得劳烦兄台再给看一下，帮下忙，能遇到一个大神不容易，大神可不能吝啬啊，先谢过了哈

95.报表相关
/*
using CrystalDecisions.CrystalReports.Engine;
using CrystalDecisions.Shared;
*/
2、水晶报表的两种格式
1）pull模式,不利用DataSet,直接从数据库中取出数据
2) push模式,使用DataSet,利用它进行数据的加载和处理等
3. 水晶报表使用的库
1)水晶报表的引擎(CREnging.dll),作用:合并数据,装换格式
2)水晶报表设计器(CRDesigner.dll),作用：设计标题，插入数据等
3）水晶报表查看控件（CRWebFormViewer.DLL）
4)需要引入的命名空间
using CrystalDecisions.CrystalReports.Engine;
using CrystalDecisions.Shared;
4、Pull模式下使用水晶报表
1）创建rpt文件
2）拖放CrystalReportViewer
3）绑定
5、读取水晶报表文件
private void ReadCRV(cryatalReportViewer crv)
{
openFileDialog dlg=new OpenFileDialog();
dlg.Title="打开水晶报表文件";
dlg.Filter="水晶报表文件(*.rpt)|*.rpt|所有文件|*.*";
if(dlg.showDialog()==DialogResult.OK)
{
crv.ReportSource=dlg.FileName;
}
}
6. B/S下读取报表的文件
private void ReadCRV(cryatalReportViewer crv,File file)
{
string strName=file.PostedFile.FileName;
if(strName.Trim()!="")
{
crv.ReportSource=strName
Session["fileName"]=strName;
}
}
在B/S中要防止数据源的丢失
priavte void Page_Load(object sender,System.EventArgs e)
{
if(Session["fileName"]!=null)
{
crv.ReportSource=Session["fileName"].ToString();
}
}
7. 假如直接从数据库中读取数据，采用PULL模式可能出现错误（登录的用户名和密码不对）
private void ReadCRV(CrystalReportViewer crv,CrystalReport cr)
{
ReportDocument reportDoc=new ReportDocument();
reportDoc.Load(Server.MapPath(cr));//要加载的rpt文件的名字
//解决登录的问题
TableLogOnInfo logonInfo = new TableLogOnInfo();
foreach(Table tb in ReportDoc.Database.Tables)
{
logonInfo=tb.LogOnInfo;
logonInfo.ConnectionInfo.ServerName="(loacl)";
logonInfo.ConnectionInfo.DatabaseName="Pubs";
logonInfo.ConnectionInfo.UserId="sa";
logonInfo.ConnectionInfo.Password="";
tb.ApplyLogOnInfo(logonInfo);
}
crv.ReportSource=reportDoc;
}
8. 采用Push模式，直接在数据源读取
private void BindReport(CrystalReportViewer crv)
{
string strProvider="Server=(local);DataBase=pubs;uid=sa;pwd=";
CrystalReport cr=new CrystalReport();
DataSet ds=new DataSet();
SqlConnection conn=new SqlConnection(strProvider);
conn.open();
string strSql="select * from jobs";
SqlDataAdapter dap=new SqlDataAdapter(strSql,conn);
adp.Fill(ds,"jobs");
cr.SetDataSource(ds);
crv.ReportSource=cr;
}
9. 导出水晶报表的文件
private void ExportCrv(CrystalReport cr)
{
DiskFileDestionOptions dOpt=new DiskFileDestionOptions();
cr.ExportOptions.ExportDestinationType=ExportDestinationType.DiskFile();
cr.ExportOptions.ExportFormatType= ExportFormatType.PortableDocFormat;
dOpt.DiskFileName="C:\output.pdf";
cr.ExportOptions.DestinationOptions=dOpt;
cr.Export();
}
private void ExportCrv(CrystalReport cr,string strType,string strPath)
{
DiskFileDestionOptions dOpt=new DiskFileDestionOptions();
cr.ExportOptions.ExportDestinationType=ExportDestinationType.DiskFile();
switch(strType)
{
case "RTF":
cr.ExportOptions.ExportFormatType=ExportFormatType.RichText;
dOpt.DiskFileName=strPath;
break;
case "PDF":
cr.ExportOptions.ExportFormatType=ExportFormatType.PortableDocFormat;
dOpt.DiskFileName=strPath;
break;
case "DOC":
cr.ExportOptions.ExportFormatType=ExportFormatType.WordForWindows;
dOpt.DiskFileName=strPath;
break;
case "XLS":
cr.ExportOptions.ExportFormatType=ExportFormatType.Excel;
dOpt.DiskFileName=strPath;
break;
default;
break;
}
cr.ExportOptions.DestinationOptions=dOpt;
cr.Export();
}
10 B/S下水晶报表的打印
priavte void PrintCRV(CrystalReport cr)
{
string strPrinterName=@"printName";
PageMargins margins=cr.PrintOptions.PageMargins;
margins.bottomMargin = 250;
margins.leftMargin = 350;
margins.rightMargin = 350;
margins.topMargin = 450;

xpdf
public OpenFileDialog ofdlg = new OpenFileDialog();//打开文件对话框
public string filename;
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
ofdlg.Filter = "pdf文件(*.pdf)|*.pdf";//选择pdf文件
if (ofdlg.ShowDialog() == DialogResult.OK)
{
filename = string.Format("{0}", ofdlg.FileName);
}
}
//传送打开文件对话框中得到的filename来做为外部程序的参数来做转化
private void button2_Click(object sender, EventArgs e)
{
Process p = new Process();
string path = "pdftotext.exe"; //进程启用外部程序
//这个exe我放在debug文件夹下面
p.StartInfo.FileName = path;
p.StartInfo.Arguments = string.Format( filename + " -");//很怪异的一行
//参数“－”表示可以得到输出流
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardInput = true;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.RedirectStandardError = true;
p.StartInfo.CreateNoWindow = true;
p.Start();
string s = p.StandardOutput.ReadToEnd();//得到pdf文档中的文本内容
textBox1.Text = s;
p.Close();
}
}
上面的程序运行后，如果是在Debug文件夹下的pdf文件就可以得到输出，可是如果在打开文件对话框中打开我桌面上的一个pdf如：@"d:\我的文档\test.pdf"，输出就会是空，但是如果把上面那怪异的一行改为：
C# code
p.StartInfo.Arguments = string.Format( @"d:\我的文档\test.pdf" + " -");
程序就又会得到输出。
呵呵，谢谢楼上的兄台，下载的xpdf中xpdftotext.exe用到的配置文件xpdfrc需要手动配置，我如果把那些字体啊，什么的映射成绝对路径下的文件，就不会出现上面的问题，但是我把配置文件中的路径改成了相对路径，于是就出现了上面的问题了，看兄台能够很轻易的就运行成功，一定是做过很多代码的，这里还得劳烦兄台再给看一下，帮下忙，能遇到一个大神不容易，大神可不能吝啬啊，先谢过了哈

95.报表相关
/*
using CrystalDecisions.CrystalReports.Engine;
using CrystalDecisions.Shared;
*/
2、水晶报表的两种格式
1）pull模式,不利用DataSet,直接从数据库中取出数据
2) push模式,使用DataSet,利用它进行数据的加载和处理等
3. 水晶报表使用的库
1)水晶报表的引擎(CREnging.dll),作用:合并数据,装换格式
2)水晶报表设计器(CRDesigner.dll),作用：设计标题，插入数据等
3）水晶报表查看控件（CRWebFormViewer.DLL）
4)需要引入的命名空间
using CrystalDecisions.CrystalReports.Engine;
using CrystalDecisions.Shared;
4、Pull模式下使用水晶报表
1）创建rpt文件
2）拖放CrystalReportViewer
3）绑定
5、读取水晶报表文件
private void ReadCRV(cryatalReportViewer crv)
{
openFileDialog dlg=new OpenFileDialog();
dlg.Title="打开水晶报表文件";
dlg.Filter="水晶报表文件(*.rpt)|*.rpt|所有文件|*.*";
if(dlg.showDialog()==DialogResult.OK)
{
crv.ReportSource=dlg.FileName;
}
}
6. B/S下读取报表的文件
private void ReadCRV(cryatalReportViewer crv,File file)
{
string strName=file.PostedFile.FileName;
if(strName.Trim()!="")
{
crv.ReportSource=strName
Session["fileName"]=strName;
}
}
在B/S中要防止数据源的丢失
priavte void Page_Load(object sender,System.EventArgs e)
{
if(Session["fileName"]!=null)
{
crv.ReportSource=Session["fileName"].ToString();
}
}
7. 假如直接从数据库中读取数据，采用PULL模式可能出现错误（登录的用户名和密码不对）
private void ReadCRV(CrystalReportViewer crv,CrystalReport cr)
{
ReportDocument reportDoc=new ReportDocument();
reportDoc.Load(Server.MapPath(cr));//要加载的rpt文件的名字
//解决登录的问题
TableLogOnInfo logonInfo = new TableLogOnInfo();
foreach(Table tb in ReportDoc.Database.Tables)
{
logonInfo=tb.LogOnInfo;
logonInfo.ConnectionInfo.ServerName="(loacl)";
logonInfo.ConnectionInfo.DatabaseName="Pubs";
logonInfo.ConnectionInfo.UserId="sa";
logonInfo.ConnectionInfo.Password="";
tb.ApplyLogOnInfo(logonInfo);
}
crv.ReportSource=reportDoc;
}
8. 采用Push模式，直接在数据源读取
private void BindReport(CrystalReportViewer crv)
{
string strProvider="Server=(local);DataBase=pubs;uid=sa;pwd=";
CrystalReport cr=new CrystalReport();
DataSet ds=new DataSet();
SqlConnection conn=new SqlConnection(strProvider);
conn.open();
string strSql="select * from jobs";
SqlDataAdapter dap=new SqlDataAdapter(strSql,conn);
adp.Fill(ds,"jobs");
cr.SetDataSource(ds);
crv.ReportSource=cr;
}
9. 导出水晶报表的文件
private void ExportCrv(CrystalReport cr)
{
DiskFileDestionOptions dOpt=new DiskFileDestionOptions();
cr.ExportOptions.ExportDestinationType=ExportDestinationType.DiskFile();
cr.ExportOptions.ExportFormatType= ExportFormatType.PortableDocFormat;
dOpt.DiskFileName="C:\output.pdf";
cr.ExportOptions.DestinationOptions=dOpt;
cr.Export();
}
private void ExportCrv(CrystalReport cr,string strType,string strPath)
{
DiskFileDestionOptions dOpt=new DiskFileDestionOptions();
cr.ExportOptions.ExportDestinationType=ExportDestinationType.DiskFile();
switch(strType)
{
case "RTF":
cr.ExportOptions.ExportFormatType=ExportFormatType.RichText;
dOpt.DiskFileName=strPath;
break;
case "PDF":

break;
case "DOC":

break;
case "XLS":
cr.ExportOptions.ExportFormatType=ExportFormatType.Excel;
dOpt.DiskFileName=strPath;
break;
default;
break;
}
cr.ExportOptions.DestinationOptions=dOpt;
cr.Export();
}
10 B/S下水晶报表的打印
priavte void PrintCRV(CrystalReport cr)
{
string strPrinterName=@"printName";
PageMargins margins=cr.PrintOptions.PageMargins;
margins.bottomMargin = 250;
margins.leftMargin = 350;
margins.rightMargin = 350;
margins.topMargin = 450;
