I am building an app that modifies a word 2010 document and it should be downloaded as pdf.I write a code to convert word to pdf but it is converting the document I upload not the modified word. How can I convert modified word to PDF.Below is the function which is not converting modified word. protected void btnUpload_Click(object sender, EventArgs e) {
if (FileUploadControl.HasFile)
{
string fileNameFromUser = FileUploadControl.FileName;
var fiFileName = new System.IO.FileInfo(fileNameFromUser);
using (MemoryStream ms = new MemoryStream())
{
ms.Write(FileUploadControl.FileBytes, 0, FileUploadControl.FileBytes.Length);
using (WordprocessingDocument sDoc = WordprocessingDocument.Open(ms, true))
{
}
lblMessage.Text = "Dokumenti u ngarkua me sukses!";
Session["ByteArray"] = FileUploadControl.FileBytes;
Session["fileNameFromUser"] = fileNameFromUser;
}
}
byte[] byteArray = (byte[])(Session["ByteArray"]);
if (byteArray != null)
{
try
{
using (MemoryStream ms = new MemoryStream())
{
ms.Write(byteArray, 0, byteArray.Length);
using (WordprocessingDocument wDoc = WordprocessingDocument.Open(ms, true))
{
var body = wDoc.MainDocumentPart.Document.Body;
var lastParagraf = body.Elements<Paragraph>().LastOrDefault();
var newParagraf = new Paragraph(
new Run(
new Text("Perdoruesi:" + " " + User.Identity.Name)));
var newParagraf2 = new Paragraph(
new Run(
new Text("Data dhe ora:" + " " + DateTime.Now.ToString())));
var newParagraf3 = new Paragraph(
new Run(
new Text("Kodi unik:" + " " + randomstring(14))));
var newParagraf4 = new Paragraph(
new Run(
new Text("Shifra:" )));
lastParagraf.InsertAfterSelf(newParagraf);
lastParagraf.InsertAfterSelf(newParagraf2);
lastParagraf.InsertAfterSelf(newParagraf3);
lastParagraf.InsertAfterSelf(newParagraf4);
}
Session["ByteArray"] = ms.ToArray();
lblMessage.Text = "U ngarkua dhe u vulos dokumenti!";
Guid pdfFileGuid = Guid.NewGuid();
var filePath = Path.GetTempFileName();
FileUploadControl.SaveAs(filePath);
var appWord = new Microsoft.Office.Interop.Word.Application();
var wordDoc = appWord.Documents.Open(filePath);
var convertedFilePath = Path.GetTempFileName();
wordDoc.ExportAsFixedFormat(convertedFilePath, Microsoft.Office.Interop.Word.WdExportFormat.wdExportFormatPDF);
Response.Clear();
Response.AddHeader("content-disposition", "attachment; filename=Converted.Pdf");
Response.AddHeader("content-type", "application/pdf");
Response.TransmitFile(convertedFilePath);
File.Delete(filePath);
File.Delete(convertedFilePath);
}
}
catch (Exception ex)
{
lblMessage.Text = "ERROR:" + ex.Message.ToString();
}
}
else
{
lblMessage.Text = "Nuk e keni zgjedhur dokumentin apo formati i dokumentit nuk pershtatet!";
}
}
Currently, here you load the data from the FileUploadControl
into session:
Session["ByteArray"] = FileUploadControl.FileBytes;
You then load the data from session into a MemoryStream
that you use to open the document for editing:
byte[] byteArray = (byte[])(Session["ByteArray"]);
if (byteArray != null)
{
try
{
using (MemoryStream ms = new MemoryStream())
{
ms.Write(byteArray, 0, byteArray.Length);
using (WordprocessingDocument wDoc = WordprocessingDocument.Open(ms, true))
At the end of this, after your edits, you copy the updated content back to session:
lastParagraf.InsertAfterSelf(newParagraf3);
lastParagraf.InsertAfterSelf(newParagraf4);
}
Session["ByteArray"] = ms.ToArray();
but; that's the last time we see session used; you then write the uploaded file to a temporary file, and use that to perform Word automation:
var filePath = Path.GetTempFileName();
FileUploadControl.SaveAs(filePath);
var appWord = new Microsoft.Office.Interop.Word.Application();
var wordDoc = appWord.Documents.Open(filePath);
So yes: this will convert the original file as uploaded, because FileUploadControl
is unrelated to the changes you made. Instead, perhaps try:
var filePath = Path.GetTempFileName();
File.WriteAllBytes(filePath, (byte[])Session["ByteArray"]);
var appWord = new Microsoft.Office.Interop.Word.Application();
var wordDoc = appWord.Documents.Open(filePath);
This should then include the changes.
Additional side observations:
appWord
, wordDoc
, filePath
, convertedFilePath
etc - all probably need some finally
love)Session
) probably isn't a good or necessary idea; I would recommend just using a local byte[]
or similar throughout in this method, and remove Session["ByteArray"]
