Exception converting Office files to PDF using ABCpdf.NET onWindows Server 2008

Question

Has anyone delt with this exception from ABCpdf? We're running on Server 2008 and only have issues converting Office files (Word and Excel). This all worked well on Server 2003. Because we're only having issues with Office files I wonder if it's related to the XPS support on Server 2008? The code that calls into this function is running as a Windows Service.

Private Overloads Function ConvertMicrosoftOfficeDocToPdf(ByVal inputFile As Byte(), ByVal fileExt As String) As Byte()
    Dim abcDoc As WebSupergoo.ABCpdf7.Doc = Nothing

    Try
        abcDoc = New WebSupergoo.ABCpdf7.Doc()

        Dim xro As New WebSupergoo.ABCpdf7.XReadOptions()
        xro.FileExtension = fileExt

        Try
            abcDoc.Read(inputFile, xro)
        Catch ex As Exception
            System.Diagnostics.Trace.Write(ex.ToString())
            Throw ex
        End Try

        Dim fileBytes As Byte() = abcDoc.GetData()
        Return fileBytes
    Finally
        If Not abcDoc Is Nothing Then
            abcDoc.Clear()
            abcDoc.Dispose()
        End If
    End Try
End Function

Hi,

I am facing a bit different error but very similar to the above mentioned error. ERROR

Following error is thrown by wcfService when reading document on line dd.Read()…

WebSupergoo.ABCpdf7.Internal.PDFException was caught

   InnerException

My Code is

byte[] officeDoc = System.IO.File.ReadAllBytes(s);                                    
WebSupergoo.ABCpdf7.XReadOptions xr = new XReadOptions();
xr.FileExtension = GetFileExtension(s);
Doc dd = new Doc();
dd.Read(officeDoc, xr);
dd.Dispose();
dd = null;

My system configuration

1) Windows Vista

2) IIS-7

3) AbcPdf 7.0.0.8 (also tried using 7.0.1.9)

4) Visual studo 2008 with SP1

5) OpenOffice.org installed

My code works fine, if I use it with a new sample web application. BUT if I use same code with WCF service and deploy it on my local machine IIS (IIS-7) then it fails to load openOffice.Org documents (but merges txt, html etc)

Thanks Surjit

Hi,

This code has resolved my above mentioned problem.

Doc pdf = new Doc();
                try
                {
                    pdf.Read(s);
                }
                catch
                {
                    //for txt files
                    WebSupergoo.ABCpdf7.Operations.XpsImportOperation import = new WebSupergoo.ABCpdf7.Operations.XpsImportOperation();
                    import.ImportAny(pdf, s, 10000);
                }

Actual problem is that the folder where you are trying write the file, give the write permission to IIS_IUSR. Then it should work.
