Unable to save documents to file stream

[chavas]

Hi,

In my project, we store files in SQL filestream. We read the byte array from file stream and using your IStreamWrapper class open the pdf file in PDF Editor. After editing, we save the file to memory stream (using Istreamwrapper) and store it back in SQL. This works fine for some pdfs. However for pdfs with fillable forms, the file does not save properly. I have some samples of PDF files which fail. I have created a a sample project to reproduce this issue. We work on Visual Studio 2013 and vb.net. The sample project is too big to upload on forum. Can you give me an email to send it to you?
Here is the code-
Step1- Select file and convert to byte array-Dim fStream As New FileStream(FileName, FileMode.Open, FileAccess.Read)
Dim br As New BinaryReader(fStream)
Data = br.ReadBytes(CInt(numBytes))

Step2- Open pdf in editor- Dim srcstream As New MemoryStream
srcstream.Write(data, 0, data.Length)
Dim srcIStream As IStreamWrapper = New IStreamWrapper(srcstream)
pdfctrl.OpenDocFrom(srcIStream)

Step3- Save pdf to memory stream and then to disk- Dim fs As New MemoryStream()
Dim srcIStream As IStreamWrapper = New IStreamWrapper(fs)
pdfctrl.Doc.Save(srcIStream, 1)
pdfctrl.Doc.Close()
srcIStream = Nothing
Dim docBytes As Byte()
docBytes = fs.ToArray()
File.WriteAllBytes("C:\123.pdf", docBytes)

In the sample, Click on 'Viewer' button to open the PDF Editor. Here click on 'Step1' to select a file and convert to byte array. Then click on step2 to open pdf in editor. Edit the pdf, then click on 'Save' to save the document at 'C:\123.pdf'. The new file gets corrupted.
We are using PDF-XChange Editor V6.0.322.4

Appreciate your help on this..

Hi Alex,

I have emailed you the project. To run the project, place the -PDFXEditCore.x86.dll , pluginsX86 folder in bin\debug folder of the project.

Hello Chavas,

Do let us know how it goes once you've had the chance to test!
As for the official release of build 323 - it's still a few weeks away - and there's no specific date set up for it yet.

Regards,
Stefan

Hi Alex,

We have verified, the issue is fixed in the development build. Now we are waiting for the final build. We use PDFXEditor in our software and our final release is stuck because of this issue.
Hence we request you to give us final build at the earliest.

Hi Chavas,

Thanks for the post and the info. - We do not provide builds earlier than their intended release date. All users will have access to the build at the same time. We don't release builds early to ensure that all features and fixes are up to 'par' and that there are no major issues.

Thanks,
