netpdf_net如何将页面生成pdf

❶ .net怎样在网页中打开pdf格式文件，不允许下载，只能在网页中浏览，求大神

page.Response.AddHeader("Content-Disposition", "attachment;filename=" + downLoad + ".xls");
while (dataLength > 0 && page.Response.IsClientConnected)
{
int lengthRead = fs.Read(buffer, 0, Convert.ToInt32(ChunkSize));
page.Response.OutputStream.Write(buffer, 0, lengthRead);
page.Response.Flush();
dataLength = dataLength - lengthRead;
}
page.Response.Close();

这是导出xls的 "attachment;filename=" + downLoad + ".xls" 这是以附件的形式所以代开的时候是以下载流打开的
你不要用附件的形式，那么它就不会允许下载
PDF document

<% response.ContentType ="application/pdf" %>
 这是网页显示pdf的网页内容头
还有以后问问题请上代码

❷ net中怎么打开指定路径下的PDF文件

需要安装adobereader

<objectclassid="clsid:CA8A9780-280D-11CF-A24D-444553540000"height="700px"width="755px">

</object>

❸ 如何用.NET将DWG文件打印为PDF

执行步骤：打开一个dwg文件，用netload加载下面代码所在的.dll文件，再输入命令plottest，就得到输出结果（一个.pdf文件）。

要用到的参考：

AcDbMgd.dll;AcMgd.dll;AutoCAD 2010 Type Library;System.Windows.Forms; AutoCAD/ObjectDBX Common 18.0 Type Library.

VB.NET:

Imports System

Imports Autodesk.AutoCAD.Runtime

Imports Autodesk.AutoCAD.Interop

Imports Autodesk.AutoCAD.Interop.Common

Imports Autodesk.AutoCAD.ApplicationServices

Imports Autodesk.AutoCAD.DatabaseServices

Imports Autodesk.AutoCAD.EditorInput

<Autodesk.AutoCAD.Runtime.CommandMethod("Plottest")> _

Public Sub PlotToPDF()

Dim activeDoc As Document = Application.DocumentManager.MdiActiveDocument

Dim ThisDrawing As AcadDocument = CType(activeDoc.AcadDocument, AcadDocument)

Dim layout As AcadLayout = ThisDrawing.ActiveLayout

Dim MediaName As String = layout.CanonicalMediaName

If MediaName.Equals("") Then

activeDoc.Editor.WriteMessage("There is no media set for the active layout.")

Return

Else

activeDoc.Editor.WriteMessage(("The media for the active layout is: " + MediaName))

End If

Try

Dim oplot As AcadPlotConfiguration = ThisDrawing.PlotConfigurations.Add("PDF", layout.ModelType)

oplot.PaperUnits = AcPlotPaperUnits.acMillimeters

oplot.StyleSheet = "monochrome.ctb"

oplot.PlotWithPlotStyles = True

oplot.ConfigName = "DWG To PDF.pc3"

oplot.UseStandardScale = True

oplot.StandardScale = AcPlotScale.acScaleToFit

oplot.PlotType = AcPlotType.acExtents

oplot.CenterPlot = True

Dim oMediaNames As Object = layout.GetCanonicalMediaNames

Dim mediaNames As ArrayList = New ArrayList(CType(oMediaNames, String()))

For Each sName As String In mediaNames

If sName.Contains(MediaName) Then

oplot.CanonicalMediaName = sName

layout.CopyFrom(oplot)

layout.PlotRotation = AcPlotRotation.ac0degrees

layout.RefreshPlotDeviceInfo()

ThisDrawing.SetVariable("BACKGROUNDPLOT", 0)

ThisDrawing.Plot.QuietErrorMode = True

ThisDrawing.Plot.PlotToFile("c:/temp/d1.pdf", "DWG To PDF.pc3")

oplot.Delete()

oplot = Nothing

Return

End If

Next

Catch es As System.Exception

System.Windows.Forms.MessageBox.Show(es.ToString)

End Try

End Sub

xRefs.Add(mPDF.Length);
strPDFMessage="1 0 obj\n";
ConvertToByteAndAddtoStream(strPDFMessage);
strPDFMessage="<< /Length 2 0 R >>\n";
ConvertToByteAndAddtoStream(strPDFMessage);
strPDFMessage="stream\n";
ConvertToByteAndAddtoStream(strPDFMessage);
////////PDF文档描述
streamStart=mPDF.Length;
//字体
strPDFMessage="BT\n/F0 " + fontSize +" Tf\n";
ConvertToByteAndAddtoStream(strPDFMessage);
//PDF文档实体高度
yPos = pageDepth - pageMargin;
strPDFMessage=pageMargin + " " + yPos +" Td\n" ;
ConvertToByteAndAddtoStream(strPDFMessage);

for(int i=0;i<xRefs.Count;i++)
{

}
ConvertToByteAndAddtoStream(strPDFMessage);
strPDFMessage="trailer\n<<\n/Size "+ (xRefs.Count+1)+"\n/Root 6 0 R\n>>\n";
ConvertToByteAndAddtoStream(strPDFMessage);

strPDFMessage="startxref\n" + streamStart+"\n%%EOF\n";
ConvertToByteAndAddtoStream(strPDFMessage);
mPDF.WriteTo(pPDF.BaseStream);

mPDF.Close();
pPDF.Close();
}
}

另外：C#中生成PDF文件的方法挺多，可以使用iTextSharp控件，还有aspose的控件也可以。这些控件的功能都很强大，所以控件的大小也会很大

❺ 在.net下如何提取PDF的文字并检索相关数据

FileStream ReadPdf = new FileStream(@"d:\books\vb.net\test.pdf", FileMode.Open);
long FileSize;
FileSize = ReadPdf.Length;
byte[] Buffer = new byte[(int)FileSize];
ReadPdf.Read(Buffer, 0, (int)ReadPdf.Length);
ReadPdf.Close();

写
FileStream CreatePdf = new FileStream(@"d:\books\vb.net\test1.pdf", FileMode.Create);
CreatePdf.Write(Buffer,0,Buffer.Length);
CreatePdf.Close();

希望能帮带你的忙~告一段落~谢谢~

❻ 如何使用.net编程给pdf文件加水印（急）

我说错了我用的itextsharp 是用于.net的现在的情况是找到了库函数的写法但老是报错希望大侠们帮看一下：

PdfReader reader = new PdfReader("C:/Documents and Settings/zeng/桌面/test1.pdf");
PdfStamper stamp = new PdfStamper(reader, new FileStream("C:/Documents and Settings/zeng/桌面/test1.pdf", FileMode.Create));
int n = reader.NumberOfPages;
int i = 0;
PdfContentByte under;
iTextSharp.text.Image im = iTextSharp.text.Image.GetInstance("C:/Documents and Settings/zeng/桌面/logo.jpg");
im.SetAbsolutePosition(440, 730);
im.ScaleAbsolute(160, 60);

while (i < n)
{
i++;
under = stamp.GetOverContent(i);
under.AddImage(im);
}
-----以上都正确
stamp.Close(); ---此处报异常说文件在被另一个程序使用。
reader.Close();

看了半天没发现哪里有打开文件没有关闭的真不知道该怎么办

❼ 在.NET中如何将pdf文件转换成我word或者html。

这个基本上没法做，要从程序上来说的话你得了解pdf和word的文件格式，太难。而且现在的商业软件都很难解决这个问题。
不过有个简单的方法就是利用online的service，网上有很多在线pdf转word的，你可以在程序里面与它们通信，提交pdf，下载word

❽ .net生成PDF文件的一个问题..

table.Padding = 0;
table.Spacing = 2; //设置这个值的大小可以解决这个问题

❾ 怎样把.net页面中的表格转换成pdf

安装Adobe
Acrobat软件，安装成功后网页有个“将网页转换为PDF”的插件功能，能将任何网页及文档转成PDF文档。
