Lots of Issues with SaveToStream

[keithn]

I have a document with 40 items to be merged, all are pretty simple fields. I am opening the template from a stream and have the following problems when executing the following code:

using (memStr = new MemoryStream())
{
document.SaveToStream(memStr, FileFormat.Doc);
}

1) For PDF I get a stack overflow exception
2) For docx every merge field gets replaced with the value twice.
3) For doc everything looks fine though Word throws errors opening the doc.

I have the latest version of the software and the hot fix. Are these known issues and is there any fix date?

ps. I can't post my template here due to it's sensitive nature but could mail it if need be.

Thanks

Downloading your latest hotfix fixed the issues with PDF getting a stack overflow.

I was able to generate the error with each item appearing twice using the Fax template sample that you include when using SaveToStream.

Hi keithn,

Thanks for your feedback.
We are sorry for the delay response for weekends here.
We are happy to hear that our latest hotfix fixed #1.
For #2 and #3, we use Fax template sample to do some tests. But we don't reproduce #2 when generate a .docx file. Could you please provide us your code? So that we can quickly reproduce your problem, and work out a solution for you soon. We get a security alert error when open the generated .doc file. Could you please tell us what was the error you encountered when opened the generated .doc file? Is also it the security alert error? Thank you!

Hello. I recently purchased and upgraded to Spire.Doc 4.6 (+ 4.6.9 hot fix) for Developer Pro Edition. I have a doc/docx stored as a varbinary(max) in an SQL2005/SQL2008 database table column. I can get the data from the column and load to a Spire.Doc.Document in some cases but in others I receive a "A disk error occurred during a write operation. (Exception from HRESULT:0X8003001D (STG_E_WRITEFAULT)) error. I have attached code I am using. It seems that small doc/docx files work correctly but not larger ones (>99KB). Please advise asap. Here is code being used.

If thisDocument._FileContent IsNot Nothing Then
Dim tempFileNamePDF As String
Dim spireFormat As FileFormat
If thisDocument._DiskFileName.Contains(".docx") Then
tempFileNamePDF = thisDocument._DiskFileName.Replace(".docx", ".pdf")
spireFormat = FileFormat.Docx
Else
tempFileNamePDF = thisDocument._DiskFileName.Replace(".doc", ".pdf")
spireFormat = FileFormat.Doc
End If

Dim ms As New MemoryStream()
Dim bw As New BinaryWriter(ms)
bw.Write(thisDocument._FileContent)
bw.Flush()

'Load the temp file into a Word Document object
Dim doc As Document = New Document(ms, spireFormat) <---- Exception occurs here !!!

'Create a new memorystream to hold the pdf and populate it (convert word to pdf here)
Dim pdfMS As New MemoryStream()
doc.SaveToStream(pdfMS, FileFormat.PDF)
doc.Close()

'Write pdf memory stream to byte array for delivery in the response
Dim pdfBytes As Byte()
pdfBytes = pdfMS.ToArray()
pdfMS.Close()

'Clear the content of the response
Response.ClearContent()
Response.ClearHeaders()
'Add the file name and attachment, which will force the open/cancel/save dialog box to show, to the header
'Response.AddHeader("Content-Disposition", "attachment; filename=" + tempFileNamePDF.Replace(userNameMashUp, ""))
Response.AddHeader("Content-Disposition", "attachment; filename=" + tempFileNamePDF)
'Add the file size into the response header
Response.AddHeader("Content-Length", pdfBytes.Length.ToString())
'Set the ContentType as saved in database
Response.ContentType = "application/pdf"
'Write the file into the response
Response.BinaryWrite(pdfBytes)
'End the response
Response.End()
Else
Session("ErrorMessage") = "Error from DocumentList: The document " & fileName & " could not be retrieved from the database."
Throw New Exception("Error from DocumentList: The document " & fileName & " could not be retrieved from the database.")
End If

Hi Gary,

We are sorry for the delay response for the weekends here.
You need to reset the position of the object MemeryStream before using, please try:

Code: Select all

bw.Write(thisDocument._FileContent)
bw.Flush()

'reset the position
ms.Position = 0

'Load the temp file into a Word Document object
Dim doc As Document = New Document(ms, spireFormat)    <--- Exception occurs here…………………………………………...


If you still has this question, please tell us.

Thanks and Regards,

The suggested fix worked like a charm...

You need to reset the position of the object MemeryStream, please try:
bw.Write(thisDocument._FileContent)
bw.Flush()

'reset the position
ms.Position = 0

'Load the temp file into a Word Document object
Dim doc As Document = New Document(ms, spireFormat) <--- Exception occurs here…………………………………………...
