VB.net2010 窗体中文本框以及图片框中内容保存为pdf文件
我一般都用aspose.word.dll来完成
先把文本框类容和图片存到word里面,然后把word专程pdf
这种方法很灵活也很生动,比直接生成pdf好多了
给你的附件有vb.net的例子还有aspose.word的dll档案
例子是从官网下的,我就是用这些例子学的,很简单。现在我很多项目需要生成pdf都是用这个完成的。
VB.NET 如何实现图片转PDF呢?
你说的不太满意是什么意思,你莫非是希望图片转换成的pdf能被选中文字并复制粘贴?
vb.net 导出PDF
利用DataWindow.net在 vb.net 下导出PDF格式文件
利用datawindow.net,导出PDF文件,实现前提:
1.安装Acrobat Distiller虚拟打印机,注意要用datawindow.net提供的打印驱动,在c:\program files\sybase\datawindow.net2.0\driver中,在文章最后,我会提供一个静态安装虚拟打印机的批处理文件,方便安装。
2.安装Ghostscript 7.05 ,在网上找,免费的。
3.导出PDF文件前,一要指定虚拟打印机名,其次导出格式为PDF(Export.PDF.Method=Distill!),另外还要指定 PDF.Distill.CustomPostScript=Yes。
具体代码如下:
''' summary
''' 导出文件
''' /summary
''' param name="sender"/param
''' param name="e"/param
''' remarks/remarks
Private Sub btnExport_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnExport.Click
Try
Dim strFilename, strPrinter As String
Dim saveDg As New SaveFileDialog
strPrinter = Me.dwPrint.Describe("DataWindow.Print.PrinterName")
saveDg.FileName = Me.dwPrint.Tag.ToString
saveDg.Filter = "Pdf文件|*.pdf|Excel文件|*.xls|所有文件|*.*"
If saveDg.ShowDialog = Windows.Forms.DialogResult.OK Then
strFilename = saveDg.FileName
If strFilename.IndexOf(".pdf") 0 Then
Me.dwPrint.Modify("DataWindow.Print.PrinterName='Acrobat Distiller'")
Me.dwPrint.Modify("DataWindow.Export.PDF.Method=Distill!")
Me.dwPrint.Modify("DataWindow.Export.PDF.Distill.CustomPostScript=Yes")
Me.dwPrint.SaveAs(strFilename, Sybase.DataWindow.FileSaveAsType.Pdf, True)
ElseIf strFilename.IndexOf(".xls") 0 Then
Me.dwPrint.SaveAs(strFilename, Sybase.DataWindow.FileSaveAsType.Excel, True)
End If
Me.dwPrint.Modify("DataWindow.Print.PrinterName='" + strPrinter + "'")
MessageBox.Show("导出成功!", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information)
End If
Catch ex As Exception
MessageBox.Show(ex.Message, "提示", MessageBoxButtons.OK, MessageBoxIcon.Error)
End Try
End Sub
