Hi Adeel,

This is my function to save the doc to pdf. I am currently using the evaluation copy of your current Aspose pdf version. We have the licence for an older version and want to update to the newer version.

public void SendToBrowserAsPdf(Document doc, string filterKeyset, Page page,bool publicFlag)//publicFlag added for hidden price, and address on the public site

{

// Modified for Feature sheet enhancements.

string includeKeys="";

//Save the document in Aspose.Pdf.Xml format into a memory stream.

MemoryStream stream = new MemoryStream();

Document mergedDoc=null;

////

//doc.Save(stream, SaveFormat.FormatAsposePdf);

Aspose.Pdf.Pdf pdf = new Aspose.Pdf.Pdf();

if (filterKeyset==null || filterKeyset.Length==0)

{

includeKeys = "INSERT #IncludeKeys VALUES('"+Guid.Empty.ToString("B")+"')"; //just give the proc something to execute

}

else

{

includeKeys = "INSERT #IncludeKeys VALUES('"+filterKeyset+"')";

}

doc.MailMerge.RemoveEmptyParagraphs = true;

mergedDoc = MergeListing(doc, includeKeys,publicFlag);

mergedDoc.MailMerge.DeleteFields();

//test send as word: mergedDoc.Save(string.Format("{0}.doc", doc.CustomDocumentProperties["TemplateName"]), SaveFormat.FormatDocument, SaveType.OpenInBrowser, page.Response);

mergedDoc.Save(stream, SaveFormat.FormatAsposePdf);

//Seek to the beginning so it can be read by XmlDocument.

stream.Seek(0, SeekOrigin.Begin);

//// //Load the document into an XmlDocument

XmlDocument xmlDoc = new XmlDocument();

xmlDoc.Load(stream);

//Make sure the images that were saved by Aspose.Word into Windows temporary

//// //folder are automatically deleted by Aspose.Pdf when they are no longer needed.

pdf.IsImagesInXmlDeleteNeeded = true;

pdf.BindXML(xmlDoc, null);

page.Response.Clear(); //prepare for binary pdf content

MemoryStream outStream = new MemoryStream();

pdf.Save(outStream); //save pdf to stream

page.Response.ClearHeaders(); //clear headers to prepare for application form at and stream of pdf direct to browser

page.Response.ContentType = "application/pdf"; //set content type for pdf

page.Response.AppendHeader("Content-Disposition","inline;filename=Document1.pdf"); // disposition to open directly in browser

page.Response.BinaryWrite(outStream.ToArray()); //write the pdf data to the browser

try

{

stream.Close();

}

catch{}

try

{

outStream.Close();

}

catch{}

mergedDoc = null;

pdf = null;

}

Thanks

Hi,

you have send me the Word template file and using that I am unable to reproduce this error. Please make sure that you are using Aspose.Words and Aspose.Pdf Latest version. I need Word or XML file. Please change this line to :

mergedDoc.Save(“C:/Aspose.XML” SaveFormat.FormatAsposePdf);

and then send me this XML file and let us investigate this issue.

Thanks.
